Detailed ways

The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

In the prior art, various chips and boards on electronic processing equipment such as notebook computers generate a large amount of heat during operation. Generally, the heat generated by the main heat sources inside the equipment (such as components that generate heat during work, such as the CPU, North Bridge, and graphics card) is discharged through the fan and the cooling grille, and the heat dissipation of the electronic processing equipment is completed.

In a low-temperature environment (such as a temperature between 0 degrees and 10 degrees), although the heat generated by the heat source in the device will slowly change the temperature of the battery in electronic processing devices such as notebook computers, the heat is mainly discharged to the computer through the fan. The outside of the device, so temperatures suitable for operation such as batteries take a long time to reach. In view of this, the present invention proposes that when electronic processing equipment such as notebook computers work in a low-temperature environment or even an extremely low temperature (below 0 degrees) environment, the heat generated by the components that can generate heat, that is, the heat source, is conducted to the low-temperature environment such as batteries and drivers. Sensitive devices, in order to increase the temperature of these low-temperature sensitive devices to a suitable working range as soon as possible.

Figure 1 shows a schematic diagram of the positional relationship of some components in the first embodiment of the electronic processing device of the present invention, wherein the first embodiment of the electronic processing device includes a housing 110, a low temperature sensitive device 120, a heat dissipation grid 130, and a temperature detection device 140 , the control device 150 and the first heat generating device 160 and the second heat generating device 170, wherein:

A low temperature sensitive device 120 is arranged on the casing 110;

The heat dissipation fence 130 is arranged on the casing 110 and has a plurality of grilles;

A temperature detection device 140, configured to detect the temperature of the low temperature sensitive device 120 when the electronic processing device is turned on, to obtain a temperature value;

The control device 150 is used to control the plurality of grids so that the heat dissipation grid 130 is in a closed state when the temperature value is lower than a threshold value (such as 10 degrees Celsius); when the temperature value is higher than or equal to the threshold value, control the plurality of grids. A plurality of grids make the heat dissipation barrier 130 in an open state, wherein, when the heat dissipation barrier 130 is in a closed state, the heat generated by the heat generating device of the electronic processing device is retained inside the housing 110 to heat the low temperature sensitive device 120 , wherein the heat generating device includes at least one of the first heat generating device 160 not affected by low temperature, the low temperature sensitive device 120 and the second heat generating device 170 affected by high temperature.

Wherein, in this first embodiment, the electronic processing device is a notebook computer, the low temperature sensitive device 120 is the battery of the notebook computer, the first heat generating device 160 is the CPU of the notebook computer, and the second heat generating device 170 For the capacitor on the motherboard of the laptop and so on. When the notebook computer is just started, due to the low ambient temperature (such as lower than 10 degrees Celsius), the temperature at this time has a great impact on the battery life and work efficiency of the notebook computer. The heat of the battery is heated to increase the temperature of the battery as soon as possible, which can better protect the battery and improve the working efficiency and working life of the battery.

The low-temperature sensitive device 120 may also be a hard disk drive or an optical disk drive of the notebook computer. At this time, the electronic processing device also includes a mainboard, and the hard disk drive or optical disk drive is arranged on the mainboard.

Fig. 2 shows a schematic diagram of the positional relationship of some components in the second embodiment of the electronic processing device of the present invention, wherein the embodiment of the electronic processing device is a notebook computer, and the low temperature sensitive device is a battery. As shown in Figure 2, the notebook computer includes a motherboard (not shown), a casing (not shown), a battery (not shown), a battery cover 1, a battery cover grid 8, a microprocessor (CPU) (not shown in the figure), CPU cooling fin (not shown in the figure) and CPU fan 5, also comprise the first cooling grille 3, the second cooling grille 4, the first grille switch (in the figure not shown), the second grille switch (not shown in the figure), heat insulation ribs 2 and temperature detection device (not shown in the figure), wherein:

The first cooling grid 3 is arranged around the CPU fan 5 (or around the CPU to conduct the heat generated by the CPU work well), and each grid is provided with a rotatable grille; the CPU fan 5 is used to accelerate Heat conduction, conduct the heat generated by the CPU through the CPU heat sink to speed up the heat dissipation of the CPU;

The second cooling grille 4 is arranged around the CPU fan 5, and each grille is provided with a rotatable grille;

The first grille switch is used to control the rotation of the grilles on the first cooling grille 3 to open or close the first grille;

The second grille switch is used to control the rotation of the grilles on the second cooling grille 4 to open or close the second grille; wherein the first grille switch and the second grille switch, namely A control device for controlling the opening or closing of the radiator grille;

Heat insulating ribs 2, made of heat insulating material, are arranged on the main board (or on the housing), extend along the plane of the main board (or housing) to the low-temperature sensitive device, and are used to connect the battery to the main board Other second heating devices affected by high temperature, such as capacitors, are isolated. When the first heat dissipation grid 3 and the second heat dissipation grid 4 are closed, by means of the conduction of the CPU fan 5, the heat generated by the CPU will be carried during work. The air of the heat is guided to the surface of the battery through the battery cover grid 8; and

The temperature detection device is connected with the first grille switch and the second grille switch, and is used to detect the temperature of the battery matched with the electronic processing device when the device is turned on. If the temperature of the battery is lower than the preset first threshold T1 (such as 10 degrees Celsius), send a closing signal to the first grille switch and the second grille switch, if the first cooling grille and the second cooling grille are in the open state at this time, the first grille switch and the second grille switch The grid switch closes the first cooling grid and the second cooling grid according to the closing signal; if the temperature of the battery is higher than the preset second threshold T2 and the first cooling grid and the second cooling grid are in the closed state, Then send an opening signal to the first grille switch and the second grille switch, and the first grille switch and the second grille switch open the first cooling grille and the second cooling grille according to the opening signal, wherein the first cooling grille The second threshold T2 is greater than or equal to the first threshold T1, and in this embodiment, the second threshold T2 is equal to the first threshold T1.

The function of the above-mentioned isolation rib 2 is to conduct the heat generated by the capacitors on the CPU and the main board to the battery surface to heat the battery when the notebook computer is just started, and at the same time isolate the second heat generated by the capacitors on the main board. The device 170 (not shown in the figure) prevents the temperature of the second heat generating device 170 from rapidly increasing under the action of heat generated by the CPU and the like, thereby affecting the working efficiency and service life.

When the first heat dissipation grill 3 and the second heat dissipation grill 4 are closed, the CPU fan 5 accelerates the air flow, accelerates the heat dissipation of the CPU, and also accelerates the temperature rise of the battery.

As shown in Fig. 2, the battery of the notebook computer is arranged on the main board, and the battery cover 1 covers the surface of the battery. When the notebook computer is working in a common environment such as room temperature, the heat generated by the battery is released from the battery cover through the battery cover grid 8, so as to avoid the accumulation of heat generated by the battery and accelerate battery aging.

When the first heat dissipation grill 3 and the second heat dissipation grill 4 are in an open state, when the notebook computer is working, the CPU fan 5 drives the air to flow, so that the driven air exchanges heat with the fins on the CPU heat sink. , the air carrying heat is exchanged to the outside of the notebook computer through the second heat dissipation grid 4 of the first heat dissipation grill 3 (the arrow in the figure indicates the direction of air flow), and the external air enters the notebook computer in a compensating manner to realize The purpose of lowering the CPU temperature.

When the first heat dissipation grill 3 and the second heat dissipation grill 4 are in the closed state, the heat generated by the operation of components such as the CPU when the notebook computer is in operation, is aided by the air flow caused by the CPU fan 5 and the heat insulation ribs. The guiding effect on the air is delivered to the surface of the battery through the battery cover grid 8, so that the temperature of the battery rises as soon as possible.

When in use, after the notebook computer is turned on in a low-temperature environment, the temperature detection device detects that the temperature of the battery is lower than the first threshold T1. The grid switch and the second grid switch send a closing signal. According to the closing signal, the first grill switch and the second grill switch close the first cooling grill 3 and the second cooling grill 4 .

The heat generated by heat sources such as the CPU cannot be dissipated through the first heat dissipation grill 3 and the second heat dissipation grill 4 driven by the flowing air caused by the CPU fan 5 . Coupled with the existence of the heat-insulating ribs 2, the heat-insulating ribs 2 have to guide the flow to the battery through the battery cover grid 8, so as to increase the temperature of the battery.

Of course, in practical applications, closing or opening the first heat dissipation grill 3 and the second heat dissipation grill 4 may also be done manually by the user according to the ambient temperature before the notebook computer is turned on.

After the notebook computer has been running for a period of time, due to the heat generated by the battery itself and the heat generated by the CPU work conducted by the CPU fan 5 and the heat insulating rib 2, the temperature of the battery is rapidly raised to the normal operating range (25 degrees to 45 degrees ), in order to avoid the temperature of the battery from continuing to rise, one should try to maintain or reduce the temperature of the battery, so as to avoid the negative impact of excessive temperature on the battery.

After the temperature detection device detects that the temperature of the battery is higher than the preset second threshold T2, it indicates that the temperature of the battery has risen to the normal operating range, and there is no need to conduct the heat generated by the CPU and other components to the battery, so these The heat escapes. The temperature detection device sends an opening signal to the first grille switch and the second grille switch, and the first grille switch and the second grille switch open the first cooling grille 3 and the second cooling grille 4 according to the opening signal . Since the first heat dissipation grill 3 and the second heat dissipation grill 4 are in the open state at this time, the heat generated by components such as the CPU, under the action of the flowing air caused by the CPU fan, passes through the open first heat dissipation grill. 3 and the second heat dissipation grill 4 to radiate to the outside of the processing equipment.

It should be noted that the heat-insulating ribs 2 not only have a flow-guiding effect, but also have a heat-insulating effect, so as to protect other components in the electronic processing equipment except the battery. Since most components in electronic processing equipment are sensitive to temperature, excessive temperature will affect the working performance and life of these components. Therefore, when conducting the heat generated by the CPU to the battery, it is necessary to Try to ensure that the heat does not affect the temperature of other components in the device. Under the heat insulation effect of the heat insulation rib plate 2, the heat generated by the heater will not be conducted to other components on the main board, and there will be no hidden dangers of failure or even safety problems of these components due to excessive temperature .

It should be noted that if the temperature detection device detects that the temperature of the battery is higher than the second threshold T2 when the device is just turned on, that is, it is already in a temperature range suitable for battery operation, it is not necessary to switch to the first grille and the second The grille switch sends an open signal. Generally, only after detecting that the temperature of the battery is lower than the first threshold T1 and first sending a shutdown signal to the first grille switch and the second grille switch, it is detected that the temperature of the battery has risen to the second threshold T2 Only when above is the case, an opening signal is sent to the first grille switch and the second grille switch, so as to turn on the first cooling grille and the second cooling grille to dissipate heat.

It should be noted that, in this embodiment, two cooling grilles are used as an example to describe the structure of the notebook computer, and the opening and closing actions of the two cooling grills are consistent. In fact, the opening and closing of the two cooling grills may also be asynchronous, that is, only controlling one of the cooling grills to open or close is also allowed. In addition, in some other embodiments, there may be one, three or more cooling grids, and the present invention does not limit the number of cooling grids.

It should be noted that the temperature of the battery can also be increased if only the heat insulation ribs 2 are provided to guide the heat generated by the CPU to the surface of the battery without closing the grid pieces of the heat dissipation grill.

FIG. 3 shows a schematic diagram of the positional relationship of some components in the third embodiment of the electronic processing device of the present invention, and the third embodiment is also a notebook computer. Compared with the second embodiment shown in FIG. 2 , the third embodiment further includes an electric heater and a heater switch. In conjunction with the second embodiment shown in Figure 2, in the third embodiment shown in Figure 3:

The temperature detection device is connected with the first grid switch, the second grid switch and the heater switch (not shown in the figure), and when it detects that the temperature of the battery is lower than a third threshold T3 (such as 0 degrees), it will send The first grid switch and the second grid switch send closing signals to close the first cooling grid 3 and the second cooling grid 4, and send a working signal to the heater switch; when the temperature of the battery is detected to be lower than When the first threshold T1 is higher than the third threshold T3, a closing signal is sent to the first grille switch and the second grille switch to close the first cooling grille 3 and the second cooling grille 4; A threshold T1 is greater than or equal to the third threshold T3. In this embodiment, the first threshold T1 is 10 degrees Celsius, and the third threshold T3 is 0 degrees Celsius; when it is detected that the temperature of the battery is higher than a fourth threshold T4, Send a stop signal to the heater 7 switch to control the electric heater 7 to stop working; wherein the fourth threshold T4 is greater than or equal to the third threshold T3, and in this embodiment the fourth threshold T4 is equal to the third threshold T3; When the temperature of the battery continues to increase and reaches higher than the second threshold T2, an opening signal is sent to the first grille switch 3 and the second grille switch 4;

The heater switch is connected with the temperature detection device and the electric heater 7, turns on the electric heater 7 for heating according to the working signal sent by the temperature detection device, and controls the electric heater 7 to stop working according to the stop signal sent by the temperature detection device;

The electric heater 7 is connected with the battery and the heater switch (connection relationship is not shown in the figure), is arranged between the CPU fan 5 and the battery, and is positioned on the same side of the heat insulation rib plate 2 as the battery, according to the position of the heater switch The control works to generate heat, and the battery or external power supply provides electric energy. The generated heat is also conducted to the battery by means of the CPU fan 5 and the heat insulating rib 2 to increase the temperature of the battery as soon as possible.

If the external power supply is selected to provide electric energy for the electric heater 7, the battery can be preheated when the electronic processing equipment is not working, that is, the external power supply can be used to provide electric energy for the electric heater 7 before the electronic processing equipment is turned on. The electric heater 7 provides heat for the components inside the electronic processing device and the matched battery, etc., so that the temperature of the electronic processing device and the battery is raised as a whole, and then the electronic processing device is turned on to run.

Due to the heat generated by the electric heater 7 and the CPU, and the heating effect generated by the operation of the battery itself, the temperature of the battery can be continuously increased. When the temperature detection device detects that the temperature of the battery is higher than the fourth threshold T4, it can send a stop signal to the heater switch to control the electric heater 7 to stop working, so as to save the power in the battery. Of course, it is also possible not to send a stop signal to the electric heater switch, so that the electric heater 7 continues to work to provide heat, so that the temperature of the battery can be raised to a suitable working temperature range as soon as possible. When the temperature of the battery continues to rise above the second threshold T2, it means that the temperature of the battery is within the normal range suitable for battery operation. The switch 4 sends an opening signal to open the first heat dissipation grill 3 and the second heat dissipation grill 4 to dissipate heat.

When the external power supply is used to heat low-temperature sensitive components such as batteries through the heater 7, the temperature detection device simultaneously operates through the external power supply to detect the temperature of low-temperature sensitive components such as batteries. After detecting that the temperature rises to the fourth threshold T4, a stop signal is sent to the heater 7 to control the electric heater 7 to stop working, and an alarm to the outside world through a sound alarm device (not shown in the figure). The user prompts that the temperature of the low temperature sensitive device has risen to the suitable working temperature range.

It should be noted that if the temperature detection device detects that the temperature of the battery is lower than the first threshold T1 but higher than the third threshold T3 when the device is just started, the stop signal may not be sent to the heater switch. If the temperature detection device detects that the temperature of the battery is higher than the first threshold T1 when the device is just turned on, it may not send a start signal to the first grille switch and the second grille switch.

In an extremely low temperature environment (such as below minus 20 degrees Celsius), only relying on the heat generated by the CPU work may not be able to rapidly increase the temperature of the battery. At this time, the heat generated by the electric heater 7 is transmitted to the battery along with the energy generated by the CPU through the CPU fan 5 and the heat insulating rib 2, so that the temperature of the battery can rise as soon as possible.

In each of the above implementations, the present invention is described with the CPU of the notebook computer as the heat source. In fact, in a notebook computer, the heat generated during work is suitable for directing to and heating low-temperature sensitive components such as the battery, including the north bridge. Fig. 4 shows the fourth embodiment of the electronic processing equipment of the present invention. Compared with the third embodiment shown in Fig. 3, the heat insulating rib 2 is not only used to guide the heat generated by the CPU when it is working. On the battery, it is also used to guide the heat generated by the north bridge (shown by the heat sink 9 of the north bridge in the figure) to the battery to heat the battery.

The above embodiments are used to illustrate some implementations of the present invention by taking the battery that protects a notebook computer with an integrated graphics card as an example. FIG. 5 shows a fifth embodiment of an electronic processing device for protecting a battery equipped with a notebook computer with an independent graphics card. As shown in Figure 5, the heat source in this fifth embodiment not only includes CPU and North Bridge (shown with the cooling fin 9 of the North Bridge in the figure), but also includes an independent graphics card (shown with the cooling fin 10 of the independent graphics card among the figures) . The heat insulation rib 2 is not only used to guide the heat generated by the CPU and the north bridge to the battery, but also used to guide the heat generated by the independent graphics card to the battery to heat the battery.

When electronic processing equipment such as notebook computers work in a low temperature environment, in addition to having a bad effect on the battery, it will also have a bad effect on drives, such as hard disk drives (Hard Disk Drive, HDD) and optical disk drives (Optical Disk Drive, ODD). . When the drive works in a low-temperature environment, the motor, the read-write head swing arm and the mechanical parts start and run, and the noise is very loud, and the life of the drive will be shortened.

In some other embodiments of the present invention, the heat generated by the heat source and the electric heater is guided by the heat insulation rib to heat the temperature of the driver. In an extremely low temperature environment, the electric heater can be heated by an external power supply, and the heat generated by the electric heater is used to preheat the electronic processing equipment. When the temperature of the driver rises to a suitable level for the driver to work, the electronic processing equipment is then turned on for work. .

After the temperature detection device in the present invention detects that the temperature of the low-temperature sensitive device is within the temperature range suitable for the device to work, it controls the heat dissipation grid to export the heat of the CPU, etc., and will not cause disadvantages to the device due to continuous heating. Not to mention the occurrence of dangerous events such as battery explosion due to continuous heating.

The electric heater in the above embodiment can be powered by the battery of the electronic processing device, but it is a low-power heater, and the electric energy in the battery will not be consumed significantly due to the use of the electric heater. Generally, the heater preheats the low-temperature sensitive device when the electronic processing device is just turned on. After the electronic processing device has been working for a period of time, the temperature of the low-temperature sensitive device will generally rise rapidly to a temperature suitable for the electronic processing device to work, so There will be no security risks. Of course, when the electronic processing equipment is not started to work, it is powered by an external power supply, and the temperature of the low-temperature sensitive device can also be raised through the operation of the electric heater. In these embodiments of protecting the driver, the temperature detection device is used to detect the temperature of the driver, and send a signal to the heat dissipation grill etc. according to the detection result.
