Referring to fig. 1, the heat dissipating apparatus includes a heat dissipating case 1 and a cooling system. The heat dissipation box body 1 comprises a cold channel 101, a storage space 102 and a hot channel 103 which are sequentially communicated along the horizontal direction and are used for storing the communication cabinet.

Optionally, in this embodiment, the heat dissipation device is an integrated structure, that is, the evaporation cavity 104 and the condensation cavity 105 are both located in the heat dissipation box 1; optionally, the evaporation cavity 104 is located at an end face of the cold channel 101, the storage space 102, and the hot channel 103, and the condensation cavity 105 is located at a side of the evaporation cavity 104 away from the storage space 102.

In some other embodiments, the heat dissipation device may also be a split structure, for example, the evaporation cavity 104 and/or the condensation cavity 105 are located outside the heat dissipation case 1.

The cooling system is used for driving the air in the evaporation cavity 104 to flow through the cold channel 101, the storage space 102 and the hot channel 103 in sequence and then return to the evaporation cavity 104.

Optionally, the cold aisle 101 is located at the rear side of the storage space 102, and the hot aisle 103 is located at the front side of the storage space 102. The air outlet of the cold channel 101 is located on the side surface of the cold channel 101 close to the storage space 102, the air inlet of the storage space 102 is located on the side surface of the storage space 102 close to the cold channel 101, and the air outlet of the cold channel 101 is communicated with the air inlet of the storage space 102. The air outlet of the storage space 102 is located on the side of the storage space 102 close to the hot channel 103, the air inlet of the hot channel 103 is located on the side of the hot channel 103 close to the storage space 102, and the air outlet of the storage space 102 is communicated with the air inlet of the hot channel 103.

After a large number of experiments, the transverse airflow flowing mode with the back inlet and the front outlet is simpler in structure, less in air flowing dead angle and more uniform in temperature field compared with the traditional vertical airflow flowing mode with the bottom inlet and the top outlet.

Of course, in some other embodiments, the positions of the cold aisle 101 and the hot aisle 103 may be interchanged to form a front-to-back and front-to-back transverse airflow flow pattern, which has the same beneficial effects as the back-to-front and front-to-back transverse airflow flow pattern, and therefore, the description thereof is omitted.

Wherein the power unit assembly, the condensing assembly 301 and the condensing fan 302 are positioned in the condensing cavity 105; the throttling assembly, the evaporation assembly and the evaporation fan 403 are positioned in the evaporation cavity 104.

It can be understood that after the power unit, the condensing fan 302 and the evaporating fan 403 are started, fresh air in the external environment enters the condensing cavity 105 through the air inlet of the condensing cavity 105 to exchange heat with the condensing assembly 301, and after the heat of the condensing assembly 301 is absorbed, the temperature rises, and then the fresh air returns to the external environment through the air outlet of the condensing cavity 105. After absorbing the cold energy of the evaporation assembly, the air in the evaporation cavity 104 becomes cold air flow, under the driving of the evaporation fan 403, the cold air flows through the cold channel 101 and horizontally enters the storage space 102, after absorbing the heat of the server in the communication cabinet, the cold air becomes hot air flow, the hot air flow continuously horizontally enters the hot channel 103, and then returns to the evaporation cavity 104 through the air outlet of the hot channel 103, the hot air flow has higher temperature, and continuously provides heat energy for the evaporation assembly in the evaporation cavity 104, so that the heat exchange efficiency of the evaporation assembly can be effectively improved, and the energy consumption of the unit can be further reduced.

It can be understood that, the air current flow mode that this embodiment provided, the hot gas flow after absorbing communication rack heat continues to participate in the heat transfer circulation of evaporation subassembly, and the heat in the hot gas flow obtains abundant recycle, so can effectively reduce the unit energy consumption.

In this embodiment, a communication channel for communicating the evaporation cavity 104 and the condensation cavity 105 is arranged between the evaporation cavity 104 and the condensation cavity 105; and a switch device for controlling the opening size of the communication channel is arranged at the communication channel. Optionally, the switch device includes a first motor and a first rotating plate 501 having a shape and a size matched with the communication channel and located in the communication channel, and further, the first rotating plate 501 can rotate around a vertical rotating shaft under the driving of the first motor so as to open or close the communication channel.

It can be understood that, referring to fig. 1, at the beginning, the first rotating plate 501 is in the 0 ° state, and the communication channel is just completely blocked by the first rotating plate 501, so the evaporation cavity 104 and the condensation cavity 105 are completely isolated, and the airflow in the evaporation cavity 104 repeatedly participates in the heat dissipation cycle of the communication cabinet, at this time, the heat dissipation device executes the circulating air heat dissipation mode.

When the first rotating plate 501 rotates a certain angle, for example, when the first rotating plate 501 is in a state of 10 °, 20 °, or 30 °, the communicating channel is divided by the first rotating plate 501 into a rear channel 602 behind the first rotating plate 501 and a front channel 601 in front of the first rotating plate 501, the evaporation cavity 104 is communicated with the condensation cavity 105, a fresh air portion entering the condensation cavity 105 enters the evaporation cavity 104 through the rear channel 602 to participate in heat dissipation of the communication cabinet, a hot air portion entering the evaporation cavity 104 enters the condensation cavity 105 through the front channel 601 to be discharged to the external environment by the condensing fan 302, and at this time, the heat dissipation device executes a mixed air heat dissipation mode. It is understood that by controlling the angle of the first rotating plate 501, the wind mixing ratio can be controlled.

Referring to fig. 2, when the first rotating plate 501 rotates to the end of one end and aligns with the end of the condensing assembly 301, the shielding effect of the first rotating plate 501 is most obvious, the amount of the fresh air entering the evaporating chamber 104 is the largest, at this time, most of the cold air entering the cold air channel 101 comes from the condensing chamber 105 and the rear channel 602, and most of the hot air entering the evaporating chamber 104 from the hot air channel 103 flows through the front channel 601 and the condensing chamber 105 and is discharged to the outside environment. At this time, the heat dissipation device can be considered to be executing a fresh air heat dissipation mode.

The refrigerants in the two refrigeration cycles are independent and do not interfere with each other. In some other embodiments, the cooling system may be a single-cycle structure including only the compressor 201 refrigeration cycle or only the fluorine pump 202 refrigeration cycle. Or a first installation space for storing the evaporation fan 403 is arranged at the air outlet of the evaporation cavity 104, a second installation space for storing the condensation fan 302 is arranged at the air outlet of the condensation cavity 105, the cooling system only comprises the evaporation fan 403 and the condensation fan 302, a power unit assembly, the condensation assembly 301, the throttling assembly and the evaporation assembly are not needed, and natural air is used for achieving heat dissipation of an object to be cooled. In some other embodiments, the compressor 201 and the fluorine pump 202 share the same condenser pipeline, and from the perspective of system pipeline connection, the gaseous refrigerant is condensed into a liquid refrigerant after passing through the condensing assembly 301, and then is depressurized by the expansion valve to liquefy the refrigerant more fully; or the gaseous refrigerant is condensed into the liquid refrigerant after passing through the condensing assembly 301, and the liquid refrigerant is firstly stored in a liquid storage tank of the fluorine pump circulation loop, is pressurized by the fluorine pump 202, and is reduced in pressure by the pump throttle valve so that the refrigerant is more fully liquefied. Further, in some other embodiments, the evaporation line may be shared.

Further, the evaporation fan 403 is located in the evaporation cavity 104 near the air inlet of the cold passageway 101, so as to facilitate sending the cold air flow into the cold passageway 101 and enhance the air pressure of the inlet air of the cold passageway 101. The evaporation assembly is of a split structure, the pump evaporation pipeline 402 is located in the evaporation cavity 104 and close to the air outlet of the hot channel 103, and the press evaporation pipeline 401 is located between the evaporation fan 403 and the pump evaporation pipeline 402.

The power unit assembly is located in the condensation chamber 105 near the evaporation fan 403. Optionally, the compressor condensation pipeline and the pump condensation pipeline are packaged into an integral structure, so that the structural compactness of the unit is improved, and the equipment volume is reduced. Specifically, the condensing fan 302 is located in the condensing chamber 105 at a position close to the pump evaporation line 402; the condensing assembly 301 is located between the power unit assembly and a condensing fan 302.

The working modes of the heat dissipation device provided by the embodiment are as follows:

(1) when the outside environment temperature is high, the refrigeration cycle system of the compressor 201 is started.

Referring to fig. 1, the hot air flow in the hot channel 103 is driven by the evaporation fan 403 to perform indirect heat exchange with the low-temperature refrigerant in the fin gaps of the evaporation assembly, and the cooled air flow is discharged into the cold channel 101; then, the heat exchange is performed between the heat exchange device and heat generating equipment such as a server in the communication cabinet, the heat exchange device becomes hot air after the temperature is raised, and the hot air returns to the hot channel 103 again, so that the heat exchange of the air flow organization in the container type data center system is completed.

Meanwhile, air in the external environment is subjected to indirect heat exchange with a high-temperature refrigerant in the fin gaps of the condensation assembly 301 under the driving action of the condensation fan 302, becomes low-heat airflow after being heated, and is discharged to the external environment again through the air outlet of the condensation cavity 105, so that the heat exchange of the external airflow organization of the container type data center system is completed.

In this mode, the refrigerant is used as an intermediate medium to carry the heat exchange between the inside and the outside of the container type data center system, the high-pressure exhaust port of the compressor 201 discharges high-temperature and high-pressure gaseous refrigerant, the high-temperature and high-pressure gaseous refrigerant enters the condensation pipeline of the compressor to release heat and then becomes medium-temperature and high-pressure gaseous refrigerant, the medium-temperature and high-pressure gaseous refrigerant is reduced in pressure by the throttle valve of the compressor to become low-temperature and low-pressure liquid or gas-liquid mixed refrigerant, the low-temperature and low-pressure gaseous refrigerant flows into the evaporation pipeline 401 of the compressor to absorb heat and finally returns to the low-pressure air suction port of the compressor 201, and the compressor cooling-heating cycle of the refrigerant is completed.

Optionally, when the external environment temperature is ultrahigh (the relative humidity is low, and the wet bulb temperature is greatly lower than the dry bulb temperature), module devices such as spraying, wet film and the like can be selected and matched on the windward side of the condensation assembly 301, or the condensation assembly 301 directly adopts an evaporative condensation device (similar to a heat exchanger structure of a cooling tower), so that the external environment temperature is reduced to the wet bulb temperature from the dry bulb, and the heat exchange effect is enhanced in an auxiliary manner.

(2) When the outside environment temperature is low, the fluorine pump 202 refrigeration cycle system can be started.

The hot air flow of the hot channel 103 is driven by the evaporation fan 403 to perform indirect heat exchange with the low-temperature refrigerant in the fin gaps of the evaporation assembly, and is changed into cold air flow after being cooled to be discharged into the cold channel 101, and then is subjected to heat exchange with heating equipment such as a server and the like in the communication cabinet, and is changed into hot air flow after being heated to return to the hot channel 103 again, so that the heat exchange of the air flow organization in the container type data center system is completed.

Meanwhile, air in the external environment is subjected to indirect heat exchange with a high-temperature refrigerant in the fin gaps of the condensation assembly 301 under the driving action of the condensation fan 302, and is changed into low-heat airflow after being heated to be discharged to the external environment again, so that the heat and cold exchange of the external airflow organization of the container type data center system is completed.

In this mode, the refrigerant is used as an intermediate medium to carry the heat exchange between the inside and the outside of the container type data center system, under the circulating pressurization driving action of the fluorine pump 202, the high-pressure liquid refrigerant is throttled by the pump throttle valve and becomes a low-pressure liquid state or a gas-liquid mixed state, enters the pump evaporation pipeline 402 to absorb heat and then is evaporated into a gaseous refrigerant, then enters the pump condensation pipeline to be condensed and released heat and then becomes a low-temperature liquid refrigerant, and enters the fluorine pump 202 again to be pressurized, so that the pump cooling and heating cycle of the refrigerant is completed.

(3) When the external environment temperature is ultralow or the external air quality is better, fresh air is used for energy-saving refrigeration (the compressor 201 can be used for mechanical refrigeration or the fluorine pump 202 can be used for energy-saving refrigeration in an auxiliary mode).

Referring to fig. 2, when the switch device is turned on, the hot air flow in the hot channel 103 enters the condensation cavity 105 through the front channel 601 under the driving action of the condensation fan 302, and then is directly discharged to the external environment through the outlet of the condensation cavity 105; air in the external environment enters the evaporation cavity 104 through the condensation component 301 and the rear channel 602 under the driving action of the evaporation fan 403, and then passes through the evaporation component and is sent into the cold channel 101 through the air outlet of the evaporation cavity 104.

Simultaneously can be through the opening angle of control first revolving plate 501, realize the proportion mixture of external environment new trend and hot channel 103's hot gas flow, perhaps open fluorine pump 202, make indoor hot-blast earlier through pump evaporation pipeline 402 recovery heat, preheat the microthermal new trend of external environment with heat circulation to condensation subassembly 301 again, prevent that external environment temperature from crossing lowly, cold air causes cold shock to the equipment device in the communication rack.

Because external environment cold wind sets up the filter screen in the wind gap and filters through condensation subassembly 301 and evaporation subassembly from the dual filtration of taking, compares the conventionality, need not regularly change the filter screen and maintain, because the heat exchanger is dirty stifled, direct water wash can, compare in directly introducing external environment new trend and get into cleaner in the container, can filter some big particulate matters by oneself, if not high to the environmental requirement, need not to select even to join in marriage the filter screen, reduce and make and fortune dimension cost. Aiming at a data center system with higher requirements on indoor environment, the filter screen can be considered to be additionally arranged on the airflow path of fresh air in the external environment, and the optional matching performance is better.

Optionally, the evaporation fan 403 and the condensation fan 302 may be axial flow fans or cross flow fans, and the number of the fans may be one, two, three or more, and each fan may be arranged vertically or laterally. The centrifugal fan is preferred, and because the power is large, the rotating speed is high, the speed can be adjusted, the air quantity is large, the air pressure is large, and the air supply distance is long.

In this embodiment, the evaporation assembly and the condensation assembly 301 may be of a flat plate type, a V-shaped, a U-shaped, or an arc structure, and may be selected according to the air inlet and outlet direction and the matching combination with the fan.

It will be appreciated that the pump evaporation line may be a single heat exchanger; the evaporator can also be integrated with an evaporation pipeline of a press into a whole, and particularly can be a part formed by bending an evaporation assembly; or may be a heat exchanger in series with the press evaporator line 401.
