Immersion liquid cooling is a typical direct contact liquid cooling in which heat-generating electronic components are immersed in a cooling liquid and the heat is removed by means of a liquid flow cycle. The immersed liquid cooling is higher in heat dissipation efficiency compared with the traditional air cooling heat dissipation mode due to the fact that the heating element is in omnibearing direct contact with the cooling liquid.

Energy saving and carbon reduction are currently the mainstream trend, and single-phase submerged liquid cooling is an emerging technology and effective solution for reducing energy consumption of data centers. In single-phase immersion liquid cooling, the cooling liquid remains in a liquid state. In general, the electronic component is directly immersed in the cooling liquid, and the cooling liquid is placed in a sealed but easily accessible container, heat is transferred from the electronic component to the cooling liquid during operation, and the cooling liquid as a heat transfer medium only undergoes temperature change during heat transfer, has no phase transition, and transfers heat completely depending on sensible heat change of a substance.

The existing single-phase immersed liquid cooling scheme mainly comprises a machine case (for example, a TANK machine case), a liquid cooling distribution unit (Cooling Distribution unit, CDU) and a cooling tower, wherein the machine case is used for accommodating equipment to be cooled, cooling liquid circulates between the machine case and the cooling tower through the liquid cooling distribution unit so as to realize a cooling function, the whole system is complex, the cost is high, and the requirement on a deployed site is high, so that the equipment with simplicity, low cost and low deployment requirement is designed, and the equipment is used for testing a server and the cooling liquid and cooling the edge type server with low power density requirement to cool, and is the main direction of the scheme design of the liquid cooling server and the cooling liquid.

However, in the single-phase immersed liquid cooling scheme of the existing single-tank design, after the cooling liquid of the immersed server absorbs the heat of the server, the temperature of the cooling liquid is increased and expanded, so that the density of the cooling liquid is reduced, and accordingly the cooling liquid flows upwards, namely, the cooling liquid with high temperature flows upwards, finally, the cooling liquid with high temperature is distributed at the middle upper part of the case, and the temperature of the cooling liquid is gradually decreased from top to bottom.

In view of the above problems, the present inventors have found that a water pump can increase the flow rate of the cooling liquid in the casing and increase the heat transfer rate between the cooling liquids by absorbing and supplying water, so that the situation that a part of servers exceeds a preset temperature due to uneven temperature distribution of the cooling liquid can be avoided, and the cooling liquid with a relatively high temperature in the middle and upper part of the casing is transported to the bottom of the casing by the water pump, so that the cooling liquid with a relatively high temperature and the cooling liquid with a relatively low temperature can perform sufficient heat transfer, and the heat of the cooling liquid in the casing is more uniform. Through the mode, the cooling liquid can circularly flow up and down in the case, so that the heat of the cooling liquid is distributed more uniformly, the heat dissipation requirement of a server is met, further, the circulating flow of the cooling liquid can further enable the cooling liquid at the bottom of the case to be fully utilized, and the utilization rate of the whole cooling liquid is improved.

The liquid cooling device provided in the embodiment of the utility model includes, but is not limited to, cooling and radiating heat generating devices such as a computer server, a board card, a high-voltage transformer, a battery and the like.

Referring to fig. 1 and 2, fig. 1 shows a schematic perspective structure of a liquid cooling apparatus according to an embodiment of the present utility model, fig. 2 shows a schematic side perspective structure of a liquid cooling apparatus according to an embodiment of the present utility model, and an arrow in fig. 1 indicates a flow direction of a cooling liquid. As shown in the drawing, the liquid cooling apparatus 10 includes: the water inlet pipe 200, the water outlet pipe 300, and the driving assembly 400 are connected to the cabinet 100.

Specifically, the box body 100 (the above case) is mainly used for containing a cooling liquid and the device to be cooled 110, wherein the device to be cooled 110 is immersed in the cooling liquid, and the cooling liquid absorbs heat generated by the device to be cooled 110, so as to achieve the effect of cooling the device to be cooled. Specifically, the box 100 has a plurality of positions for inserting the device 110 to be cooled, and the device 110 to be cooled may be, but not limited to, a server, a board card or other IT devices, for example, the box 100 may place 4 1U servers or board cards, or may place 2U servers or 1 4U servers. The cooling liquid is a liquid having a high boiling point, such as an electron-chlorinated liquid and a synthetic oil.

It should be noted that, after the cooling liquid absorbs the heat of the device to be cooled 110, the cooling liquid with high temperature flows upward, so that the temperature of the cooling liquid decreases from top to bottom along the height direction, and therefore, in order to ensure the cooling effect of the device to be cooled 110, the device to be cooled 110 is generally immersed in the cooling liquid at the middle position of the box 100, and therefore, the temperature of the cooling liquid at the middle position of the box 100 is higher than that of the edge of the box 100.

In this embodiment, in order to increase the flow rate of the cooling liquid, so that the heat of the cooling liquid in the tank 100 is more uniform, the driving assembly 400 is disposed in the tank 100, and both ends of the driving assembly 400 are respectively communicated with the water inlet pipe 200 and the water outlet pipe 300.

The relatively higher temperature coolant sucked by the inlet pipe 200 may be inputted into the outlet pipe 300 by the driving assembly 400. The water outlet pipe 300 may be provided in a strip shape or a ring shape, and the water outlet pipe 300 is provided at the bottom of the tank body 100, so that the water outlet pipe 300 can output the cooling liquid with higher relative temperature to the bottom of the tank body 100 under the driving of the driving assembly 400, and the cooling liquid with higher relative temperature can be ensured to sufficiently perform heat transfer with the cooling liquid with lower relative temperature.

In this embodiment, the driving assembly 400 may use a magnetic pump, a submerged pump, a pipeline pump, and other water pumps, after the driving assembly is powered on to run, the cooling liquid with higher relative temperature at the middle and upper parts in the box body 100 can be driven to be input into the water inlet pipe 200 through the water inlet hole 210, and be output to the bottom of the box body 100 through the water outlet hole 310 on the water outlet pipe 300, so that the cooling liquid with higher relative temperature can exchange heat with the cooling liquid with lower relative temperature in the bottom and rising process, so that the heat of the cooling liquid in the box body 100 is more uniform, and further, the flow speed of the cooling liquid at the bottom of the box body 100 can be enhanced, so that the cooling liquid at the bottom of the box body 100 can be fully utilized, and the utilization rate of the cooling liquid in the box body 100 is improved.

In this process, the driving assembly 400 can realize the absorption of the cooling liquid by the water inlet pipe 200 and the output of the cooling liquid by the water outlet pipe 300, so that the cooling liquid at the bottom of the box body 100 flows upwards and towards the center, and simultaneously, the cooling liquid at the middle upper part in the box body 100 flows towards the center to form a circulation, thus realizing the circulation flow of the cooling liquid in the box body 100, and enabling the cooling liquid with high relative temperature to exchange heat with the cooling liquid with low relative temperature more quickly, thereby improving the heat transfer speed of the cooling liquid. Further, the circulating cooling liquid can transfer heat to the inner wall of the box body 100, the inner wall can absorb the heat of the cooling liquid, and the heat is transferred to the external environment through the box body 100, so that the cooling liquid in the box body 100 is cooled rapidly.

Further, a sealing ring may be provided on the via 105 to prevent the coolant from leaking out of the tank 100 through the via 105.

In order to increase the circulation speed of the cooling liquid in the tank 100 to make the heat of the cooling liquid more uniform, the present utility model further proposes an embodiment, please continue to refer to fig. 1, in which the number of the water inlets 210 is plural, and the apertures of the water inlets 210 gradually decrease from top to bottom along the height direction.

Specifically, the provision of a plurality of water inlet holes 210 can increase the speed of the cooling liquid absorbed in the middle upper portion of the water inlet pipe 200. Further, the apertures of the plurality of water inlet holes 210 are gradually decreased from top to bottom along the height direction, so that the water inlet holes 210 with larger apertures are closer to the cooling liquid with higher temperature, and the cooling liquid sucked by the water inlet holes 210 with larger apertures is more and the temperature of the cooling liquid is higher, and the flow rate of the cooling liquid sucked by the water inlet pipe 200 is ensured to be gradually decreased from top to bottom, so that the upward flow speed of the cooling liquid is increased, the transverse flow speed of the cooling liquid from the peripheral edge to the center is increased, the upward flow speed of the cooling liquid at the bottom of the box 100, the center and the circulating flow speed of the cooling liquid at the middle upper part to the center are increased, and further, more cooling liquid with higher relative temperature can be circulated to the bottom in the box 100 to exchange with the cooling liquid with lower relative temperature.

In some embodiments, the plurality of water inlet holes 210 may be uniformly arranged at the middle upper part of the water inlet pipe 200, the apertures of the plurality of water inlet holes 210 may be set to be the same, and the distance between two adjacent water inlet holes 210 is gradually decreased from top to bottom along the height direction, which may also enable the water inlet pipe 200 to suck more cooling liquid with higher relative temperature.

Through the aperture that sets up a plurality of inlet holes 210 from top to bottom along the direction of height, can make the circulation flow rate of coolant liquid in the box 100 faster for heat transfer between the coolant liquid is faster, more even, and further, the speed that coolant liquid circulation flows improves can also further improve the efficiency that box 100 carries out heat exchange with the coolant liquid.

In order to make the heat of the cooling liquid in the tank 100 more uniform, the present utility model further proposes an embodiment, please continue to refer to fig. 1, in which the number of the water outlets 310 is plural, and the distance between the water outlets 310 and the driving assembly 400 is proportional to the pore size thereof.

Specifically, the provision of a plurality of water outlet holes 310 increases the speed at which the water outlet pipe 300 outputs the cooling liquid to the bottom of the tank 100, thereby increasing the heat transfer speed between the cooling liquids. Further, since the internal liquid pressure of the outlet pipe 300 is smaller as the distance from the driving unit 400 is further, the distance between the plurality of outlet holes 310 and the driving unit 400 is set in proportion to the size of the apertures of the plurality of outlet holes 310, that is, the closer the distance between the outlet holes 310 and the driving unit 400 is, the smaller the aperture of the outlet holes 310 is, and the farther the distance between the outlet holes 310 and the driving unit 400 is, the larger the aperture of the outlet holes 310 is. In this case, due to the effect of the internal pressure of the water outlet pipe 300, the flow rate of the cooling liquid output by the water outlet hole 310 with a large aperture and the flow rate of the cooling liquid output by the water outlet hole 310 with a small aperture can be kept basically the same, so that the heat exchange efficiency between the cooling liquids is the same, and the heat between the cooling liquids in the tank 100 is more uniform.

In some embodiments, the plurality of water outlet holes 310 may be uniformly disposed on the water outlet pipe 300, and the diameters of the plurality of water outlet holes 310 may be set to be the same, and the distance between two adjacent water inlet holes 210 farther from the driving assembly 400 may be set to be smaller, which may also keep the flow rate of the cooling liquid outputted from the water outlet pipe 300 through the water outlet holes 310 substantially the same.

In order to improve the heat exchange efficiency between the cooling liquid and the inner wall of the tank 100, the present utility model further proposes an embodiment, please continue to refer to fig. 1, in which the water outlet pipe 300 is annular and is disposed around the bottom of the tank 100.

Specifically, since one end of the water outlet pipe 300 is communicated with the driving assembly 400, when the water outlet pipe 300 is in a ring shape, under the driving action of the driving assembly 400, the cooling liquid can flow to two annular circles respectively, and is output to the bottom of the periphery of the box body 100 from different positions of the water outlet pipe 300, so that the contact between the cooling liquid is more sufficient. The water outlet pipe 300 is annular and surrounds the bottom in the box 100, and may be that the water outlet pipe 300 is arranged close to the bottom of the inner wall of the box 100 to form the annular water outlet pipe 300, so that the cooling liquid output by the water outlet pipe 300 under the driving action of the driving assembly 400 can flow upwards fully along the inner wall of the box 100.

Through setting up into the annular and encircle in the bottom of box 100 outlet pipe 300, can make the coolant liquid that relative temperature is higher carry out abundant heat transfer with the coolant liquid that relative temperature is lower of box 100 bottom all around to make outlet pipe 300 through the coolant liquid of apopore 310 output can flow along the inner wall of box 100 fully, carry out the heat exchange with the inner wall of box 100 fully, thereby improve the heat exchange efficiency of coolant liquid and the inner wall of box 100.

In order to improve the heat exchange efficiency of the inner and outer walls of the case 100, the present utility model further proposes an embodiment, please continue to refer to fig. 3, and fig. 4 is a schematic diagram of the outer wall structure of the case, wherein both the inner wall and the outer wall of the case 100 are provided with heat dissipation fins 120.

Specifically, in order to enhance the contact area of the inner wall of the case 100 with the coolant and the contact area of the outer wall with the external air, the heat dissipation fins 120 are disposed on all inner walls and all outer walls of the case 100, wherein the structure of the heat dissipation fins 120 may include, but is not limited to, a winding type, a serial type, a soldering type, or a rolling type.

In this case, when heat generated from the heat dissipating device 110 immersed in the case 100 is transferred to the case 100 through the cooling liquid, the heat dissipating fins 120 provided on the inner wall may effectively increase the heat exchanging area of the cooling liquid and the case 100, thereby enhancing the heat exchanging efficiency of the cooling liquid and the case 100. After the heat of the cooling liquid is absorbed by the box body 100, the heat exchange area of the box body 100 and the external air can be effectively increased by the heat dissipation fins 120 arranged on the outer wall, so that the heat exchange efficiency of the box body 100 and the external air is enhanced.

By providing the heat dissipation fins 120 on the inner and outer walls of the box 100, the contact area between the cooling liquid and the external gas and the inner and outer walls of the box 100 can be increased, so that the heat exchange efficiency of the inner and outer walls of the box is improved, and the heat dissipation efficiency of the liquid cooling device 10 to the heat dissipation device 110 is improved.

In some embodiments, to reduce the probability of the fins 120 scratching maintenance personnel during operation, the fins 120 on both the inner and outer walls of the box 100 are configured as beveled chamfer structures.

In order to improve the heat exchange efficiency of the heat dissipating fin 120, the present utility model further proposes an embodiment, please continue to refer to fig. 4, in which the heat dissipating fin 120 is disposed along the height direction (the direction shown by the z-axis in fig. 4).

The heat dissipation fins 120 are extended in the height direction, that is, passages in the up-down direction may be formed between the heat dissipation fins 120. Specifically, for the heat dissipation fins 120 on the inner wall of the case 100, when the cooling liquid in the case 100 absorbs the heat of the device 110 to be cooled, the cooling liquid expands to reduce the density of the cooling liquid and flow upwards, so that when the heat dissipation fins 120 form channels in the vertical direction, the cooling liquid is facilitated to form channels, thereby increasing the flow speed of the cooling liquid and further increasing the heat exchange efficiency of the heat dissipation fins 120 on the inner wall of the case 100 and the cooling liquid. For the heat dissipation fins 120 on the outer wall of the box 100, after the external air absorbs the heat of the heat dissipation fins 120, the external air also expands to reduce the density of the external air, so as to flow upwards, therefore, when each heat dissipation fin 120 forms a channel in the up-down direction, the external air is facilitated to form an air channel, so that the flow speed of the external air is increased, and the heat exchange efficiency of the heat dissipation fins 120 on the outer wall of the box 100 and the external air is further increased.

By extending the heat dissipation fins 120 along the height direction, the heat exchange efficiency between the heat dissipation fins 120 on the inner wall of the box body 100 and the cooling liquid and the heat exchange efficiency between the heat dissipation fins 120 on the outer wall and the external air can be effectively improved, so that the heat dissipation efficiency of the liquid cooling device 10 to the heat dissipation device 110 is effectively improved.

In order to enhance the heat dissipation capability of the liquid cooling apparatus 10, the present utility model further proposes an embodiment, and please continue to refer to fig. 4, the heat dissipation fins 120 disposed on the outer wall of the case 100 include a first fin portion 121 and a second fin portion 122, the first fin portion 121 and the second fin portion 122 are disposed at intervals along the height direction (the direction indicated by the z-axis in fig. 4), and a fan 130 is disposed between the first fin portion 121 and the second fin portion 122, and the fan 130 is used for blowing the gas from the first fin portion 121 to the second fin portion 122.

Since the heat generated by the main heating element of the device 110 to be cooled is increased correspondingly due to the long-time operation, in this case, if the liquid cooling device 10 only depends on the cooling fins 120 on the inner and outer walls of the box 100 to cool the cooling liquid, the cooling requirement of the device 110 to be cooled is not satisfied, so in order to avoid this situation, the fan 130 is added to the liquid cooling device 10, so as to realize the function of auxiliary heat dissipation of the liquid cooling device 10 when the heat dissipation capability of the cooling fins 120 cannot satisfy the requirement.

Specifically, the first fin portion 121 and the second fin portion 122 are disposed at intervals along the height direction, which means that the lower half portion of the heat dissipation fin 120 is the first fin portion 121, the upper half portion is the second fin portion 122, and the interval between the first fin portion 121 and the second fin portion 122 is large enough to accommodate the position where one fan 130 is mounted. The fans 130 may be installed on one of the outer walls of the case 100 or on all of the outer walls of the case 100, and the number of the fans 130 may be one or more according to different heat dissipation requirements, for example, in order to cope with the higher heat dissipation requirements, the fans 130 may be installed at spaced positions between the first fin portion 121 and the second fin portion 122 around the outer wall of the case 100. When the fan 130 is operated, the flow speed of the air is greatly increased, and the air is rapidly blown from the first fin portion 121 to the second fin portion 122, so that more air can rapidly absorb the heat of the heat dissipation fins 120, the temperature of the heat dissipation fins 120 is reduced, and the heat exchange efficiency of the heat dissipation fins 120 and the cooling liquid is improved, so as to achieve the effect of assisting heat dissipation.

By arranging the fans 130 at the interval positions between the first fin portions 121 and the second fin portions 122, the heat exchange efficiency of the gas and the heat dissipation fins 120 can be improved, so that the heat exchange capacity of the heat dissipation fins 120 and the cooling liquid can be improved, and the heat dissipation requirement of the equipment 110 to be dissipated can be further met.

In order to enhance the heat dissipation efficiency of the liquid cooling apparatus 10, the present utility model further proposes an embodiment, please continue to refer to fig. 2 and 4, in which the inner wall of the box 100 is provided with a temperature sensor 140, and the temperature sensor 140 is used for detecting the temperature information of the cooling liquid. The box 100 further includes a controller 150, where the controller 150 is electrically connected to the temperature sensor 140, and the controller 150 is configured to receive temperature information sent by the temperature sensor 140. The controller 150 is further electrically connected to the fan 130, and the controller 150 is further configured to control the fan 130 to operate when the temperature information is greater than a preset temperature threshold.

Specifically, since the cooling liquid with higher temperature has low density, it flows upward, and the cooling liquid with low temperature has higher density, it flows downward, and therefore, compared with the temperature of the cooling liquid at the top and bottom of the box 100, the temperature of the cooling liquid in the middle of the box 100 can more accurately reflect the temperature of the device 110 to be cooled, and therefore, the temperature sensor 140 can be disposed in the middle of the inner wall of the box 100 to detect the temperature information of the cooling liquid, so that the temperature of the device 110 to be cooled can be grasped in time.

The connection of the temperature sensor 140 to the controller 150 means that communication is possible between the temperature sensor 140 and the controller 150, and when the temperature sensor 140 detects the temperature information of the coolant, the temperature information is transmitted to the controller 150. Meanwhile, the controller 150 is connected with the fan 130, and the on-off and the operation power of the fan 130 can be controlled through the controller 150.

When the controller 150 analyzes that the temperature of the cooling liquid is higher than the preset temperature threshold, it indicates that the liquid cooling device 10 can not meet the heat dissipation requirement by only dissipating the heat through the heat dissipation fins 120, at this time, the controller 150 sends a running signal to the fan 130 to control the fan 130 to run, and blow the air from the first fin portion 121 to the second fin portion 122, so as to enhance the heat exchange efficiency of the heat dissipation fins 120 and the external air, and achieve the effect of assisting in heat dissipation. In this way, the heat radiation effect of the heat radiation fins 120 can be monitored, and the cooling liquid can be radiated in time.

In some embodiments, when the controller 150 analyzes that the temperature of the cooling liquid is still far above the preset temperature threshold, for example, 10 ℃, after the fan 130 is operated for a period of time, the controller 150 may send a signal to the fan 130 to increase the operation power of the fan 130, thereby increasing the flow rate of the gas and further enhancing the heat exchange efficiency of the heat dissipation fins 120 and the external gas.

By arranging the temperature sensor 140 on the inner wall of the box body 100 to detect the temperature information of the cooling liquid and transmitting the temperature information to the controller 150, the controller 150 can timely control the operation of the fan 130 when the temperature of the cooling liquid exceeds a preset temperature threshold value, so that the heat exchange efficiency of the heat dissipation fins 120 and the external gas is continuously enhanced, the temperature of the cooling liquid is continuously reduced, the temperature of heating components of the equipment 110 to be cooled is further reduced, and the equipment 110 to be cooled can work normally.

In order to monitor the temperature change of the cooling liquid in real time, the utility model further provides an embodiment, please continue to refer to fig. 4, wherein a display 160 is further disposed on the outer wall of the case 100, the display 160 is connected to the controller 150, and the display 160 is configured to receive and display the temperature information sent by the controller 150.

In order to monitor the temperature of the cooling liquid in real time, a display 160 is installed on the upper portion of the outer wall of the box body 100, the display 160 can use a touch display screen, and the display 160 is in communication connection with the controller 150, so that the display 160 can receive and display temperature information uploaded by the controller 150, in this way, the temperature change condition of the cooling liquid can be directly mastered by the display 160, and an operation and maintenance person can directly master the operation condition of the liquid cooling device 10 by the display 160.

In order to facilitate maintenance of the heat dissipating device 110 by operation staff, the present utility model further provides an embodiment, please continue to refer to fig. 4, in which an openable upper cover 170 is provided on top of the case 100.

Specifically, the upper cover 170 may be a reversible upper cover 170, one side of which is welded to the box 100, or may be an independent upper cover 170 that is not connected to the box 100, and by setting the openable upper cover 170, observation of the performance status of the cooling liquid and detection of the running state of the equipment 110 to be cooled can be achieved in the running process of the liquid cooling equipment 10, and meanwhile, the insertion, extraction and maintenance of the equipment 110 to be cooled in the box 100 by operation and maintenance personnel can be more convenient.

In the present embodiment, since the high boiling point cooling liquid is used to dissipate heat from the device 110 to be cooled, the cooling liquid is not gasified and volatilized when the upper cover 170 is opened, so that the loss of the cooling liquid can be avoided.

In some embodiments, a latch may be disposed on an outer wall of the case 100, and the latch is locked after the upper cover 170 is closed, so as to prevent the upper cover 170 from being opened when the liquid cooling apparatus 10 is carried, thereby preventing pollution to the cooling liquid. Further, the sealing rings 106 may be disposed on both the upper cover 170 and the tank 100, so as to enhance the sealing performance of the entire tank 100 and further reduce the pollution probability of the cooling liquid.
