Description

Heat sink capable of automatic opening and closing, heat sink system and heat dissipation method thereof

technical field

The invention relates to a heat dissipation seat, in particular to a heat dissipation seat, a heat dissipation seat system with the heat dissipation seat and a heat dissipation method thereof.

Background technique

Since the computer was invented, it has become an indispensable part of the general public's life so far. In order to meet the various needs of users, various types of computer models have been derived, such as personal computers (Personal Computer, PC ), a notebook computer (Notebook, or called a laptop computer (Laptop)) or a barebone system, etc. Wherein, the notebook computer, because of its convenience of being portable, caused widespread repercussions as soon as it was launched, and is still one of the most popular computer models among users.

With the progress of the times and the development of the semiconductor industry, the operating capability of computer hardware is getting higher and higher, and the processing speed is getting faster and faster. However, because it is continuously in a high-speed operating environment, the heat energy generated also increases accordingly. A general personal computer has a relatively large casing, and the inside of the casing has a relatively wide accommodating space. In addition to a better heat dissipation effect, one or more cooling fans or heat sinks can also be added in the casing, so as to serve as the center. The processing unit (Central Process Unit, CPU), display card, memory and other hardware that is prone to heat are used for heat dissipation. In order to maintain its portability, general notebook computers usually limit the weight and volume within a certain range, so that there is no enough space to provide additional cooling fans or heat sinks. Therefore, after the notebook computer is used for a certain period of time, its fuselage (especially the bottom of the fuselage) will obviously heat up, even hot. In this case, if you ignore it and continue to use it, the operation of the computer hardware may start to slow down, and eventually it may even cause the hardware to burn out.

In view of this, many cooling pads that can dissipate heat for notebook computers have been proposed in the market, for example, as shown in FIG. 1 , which is a schematic diagram of a cooling pad in the prior art. The heat dissipation pad 10 shown in FIG. 1 is a base made of a heat dissipation material (such as aluminum). When a notebook computer (not shown) is placed on the heat dissipation pad 10, the bottom of the notebook computer In direct contact with the placing surface 11 of the heat dissipation pad 10 , the heat dissipation effect can be produced due to the material of the heat dissipation pad. Furthermore, the heat dissipation pad 10 has a switch 12, and one or more fans 13 are arranged at the bottom of the placement surface 11. When a power cord 14 of the heat dissipation pad 10 is connected to a power supply, power can be provided to the heat dissipation pad. 10, so as to turn on the fan 13 through the switch 12 to enhance the heat dissipation function of the heat dissipation pad 10.

For this reason, above-mentioned traditional cooling pad 10 at least has the following disadvantages:

1. The switch 12 needs to be switched manually to trigger the fan 13 to be turned on and off. If you forget to turn on the switch 12, then the cooling pad 10 cannot effectively dissipate heat, which is useless; and if you forget to turn off the switch 12 after it is turned on, the fan 13 will continue to run, which will cause unnecessary waste of power.

2. The fan 13 usually only has a fixed rotation speed, which cannot be adjusted according to the actual temperature change of the notebook computer, so the heat dissipation effect that can be achieved is quite limited.

The temperature detection device 22 is set on the hardware inside the computer 2 , such as the motherboard, the memory or the central processing unit 21 , so as to detect the temperature of the above-mentioned hardware. The central processing unit 21 is electrically connected to the temperature detection device 22, receives a detection data reported by the temperature detection device 22, and generates a control command C1.

The heat sink 3 has a body 30 , which is made of a material with good thermal conductivity such as aluminum or copper. The control unit 31 , the receiving end USB data transmission line 32 and the heat sink 33 are disposed in the body 30 . Wherein, the interface of the receiving end USB data transmission line 32 is exposed outside the base body 30 so as to be connected to the sending end USB data transmission line 23 through the USB transmission line L1.

If the sending end USB data transmission line 23 and the receiving end USB data transmission line 32 are complete USB transmission interfaces, then the heat sink 3 receives power from the computer 2 after the connection is established, and provides it to the control unit 31 and the Heat sink 33 is used.

For another example, when the cooling fan 332 starts and the temperature of the computer 2 is greater than a second threshold, the central processing unit 21 sends the control command C1 to increase the speed of the cooling fan 332; when the cooling fan 332 starts, And when the temperature of the computer 2 is less than a third threshold value, the central processing unit 21 sends the control command C1 to reduce the speed of the cooling fan 332; When the temperature of the computer 2 is lower than a fourth threshold, the central processing unit 21 sends the control command C1 to turn off the cooling component 331 or/and the cooling fan 332 . Wherein, the first threshold value is lower than the second threshold value, the fourth threshold value is lower than the third threshold value, and the first threshold value is approximately equal to the fourth threshold value, which is the refrigeration component 332 or/ And the reference temperature for starting/closing the cooling fan 332 , the second threshold value is approximately equal to the third threshold value, which is the reference temperature for increasing/decreasing the operating speed of the cooling fan 332 . The above descriptions are only preferred embodiments of the present invention and should not be limited thereto.

Finally, after the central processing unit 21 generates the control command C1 in the step S18, the computer 2 transmits the control command C1 to the outside through the USB data transmission line 23 at the sending end (step S20).

After the step S20, the heat sink 3 receives the control command C1 output by the computer 2 through the receiving end USB data transmission line 32 (step S30), and then the control unit 31 according to the content of the control command C1 Control the action of the cooling device 33 (step S32). Finally, the cooling component 331 is activated or deactivated under the control of the control unit 31 (step S34), and the cooling fan 332 is activated, deactivated or changes operating speed under the control of the control unit 31 (step S36).

Continue referring to FIG. 6 and FIG. 7 , which are block diagrams and connection schematic diagrams of another preferred embodiment of the present invention. It is worth mentioning that the receiving end USB data transmission line 32 in the heat sink 3 can also be realized through a Bluetooth transmission interface 32'. What's more, the receiving end USB data transmission line 32 and the Bluetooth transmission interface 32' can also exist at the same time, the user of the heat sink 3 can decide to connect the computer 2 and the computer 2 through the USB transmission interface or the Bluetooth transmission interface. Heat sink 3. The bluetooth transmission interface 32' is electrically connected to the control unit 31, and the computer 2 is connected to an external bluetooth transmission module 4 through the sending end USB data transmission line 23 (for example, the bluetooth transmission module 4 using the USB transmission interface in FIG. 7 ), is connected to the Bluetooth transmission interface 32' in the heat sink 3 through wireless transmission, so as to wirelessly transmit the control command C1.
