Description

Technical Field

[0001] The present application relates to the field of liquid cooling technology, and in particular to a liquid supply module, a cooling system and an electronic device. Background Art

[0002] At present, liquid cooling is widely used in electronic devices. Liquid cooling systems are usually installed in electronic devices such as servers and switches to cool and dissipate heat from chips or other electronic components inside the electronic devices.

[0003] Liquid cooling usually involves installing a cold plate and a coolant circulation pipeline connected to the cold plate in an electronic device. The cold plate is placed in contact with the hot chip or electronic device, and the coolant is driven to circulate to remove the heat from the chip or electronic device. However, the liquid cooling method has the problem of loss of coolant during the circulation process, which reduces the cooling effect. Summary of the invention

[0004] In view of this, the present application provides a liquid supply module that is conducive to replenishing cooling liquid.

[0005] Some embodiments of the present application provide a liquid supply module, which includes a liquid storage mechanism, a power mechanism and a one-way valve. The liquid storage mechanism is separated by a first cavity and a second cavity, and the first cavity and the second cavity are both used to contain coolant. The power mechanism is connected to the second cavity, and the power mechanism provides power for the coolant to flow out of the second cavity and flow back into the second cavity. The one-way valve is provided in the liquid storage mechanism, and the one-way valve connects the first cavity with the second cavity in one direction. The one-way valve is configured to close when the power mechanism drives the coolant in the second cavity, and allows the coolant in the first cavity to flow to the second cavity in one direction when the power mechanism stops working.

[0006] In the above embodiment, the first cavity is used to replenish the coolant in the second cavity, and the one-way valve is configured to close when the power mechanism drives the coolant in the second cavity, so that the first cavity and the second cavity are isolated when the power mechanism drives the coolant in the second cavity to circulate, which is conducive to reducing the impact of the circulation system on the coolant in the first cavity. The one-way valve is configured to allow the coolant in the first cavity to be replenished into the second cavity when the power mechanism stops working, which is conducive to the liquid supply module replenishing the circulating coolant, solving the problem of reduced cooling effect caused by loss of coolant during the circulation process.

[0007] In some embodiments, the first cavity and the second cavity are arranged in sequence along the direction of gravity. When the one-way valve is opened, the coolant in the first cavity enters the second cavity through the one-way valve due to the action of gravity.

[0008] In the above embodiment, the first cavity and the second cavity are arranged in sequence along the direction of gravity, which is conducive to replenishing the liquid in the first cavity into the second cavity. There is no need to provide other liquid driving devices, which is conducive to reducing the overall space occupied by the liquid storage mechanism and saving costs.

[0009] In some embodiments, along the direction of gravity, the power mechanism is disposed on a side of the first cavity facing away from the second cavity.

[0010] In the above embodiment, the power mechanism is arranged on the side of the first cavity away from the second cavity, which is beneficial to reducing the space occupied by the power mechanism in the direction perpendicular to the direction of gravity, and is also beneficial to connecting the power mechanism with the coolant at the bottom of the second cavity, thereby reducing the risk of the power mechanism having difficulty in driving the coolant to circulate after the coolant level drops due to the connection position between the power mechanism and the second cavity being too high.

[0011] In some embodiments, the liquid storage mechanism is provided with a liquid discharge port connected to the second cavity, the power mechanism has a first liquid passing end and a second liquid passing end, the first liquid passing end extends into the liquid discharge port and is fixed to the liquid storage mechanism, and the second liquid passing end is connected to an external pipeline.

[0012] In the above embodiment, the first liquid-passing end of the power mechanism is directly fixed and connected to the discharge port of the liquid storage mechanism, so that the liquid storage mechanism and the power mechanism are integrated, which saves the pipeline between the liquid storage mechanism and the power mechanism and reduces the number of pipeline connections, thereby helping to reduce the risk of coolant loss from the pipeline connections.

[0013] In some embodiments, the liquid supply module further includes a liquid level detector, which is connected to the liquid storage mechanism and is at least partially located in the first cavity.

[0014] In the above embodiment, the liquid level detector is used to detect the liquid level of the coolant in the first cavity. In the embodiment with an automatic refilling mechanism, it is helpful to send refilling information to allow the automatic refilling mechanism to refill the liquid. In the embodiment of manual refilling, it is helpful to remind the manual refilling in time, which is beneficial to further improve the service life of the liquid supply module.

[0015] In some embodiments, the liquid supply module also includes a temperature detector and a heater, the temperature detector is connected to the liquid storage mechanism and is at least partially located in the second cavity, and the heater is connected to the liquid storage mechanism and is at least partially located in the second cavity.

[0016] In the above embodiment, the temperature detector is used to detect the temperature in the second cavity. When the temperature detector detects that the temperature of the coolant in the second cavity is too low, it can be judged that the ambient temperature is low, there are phenomena such as pipe icing, and the power mechanism is difficult to drive the coolant in the second cavity. The temperature detector outputs a heating signal when it detects that the temperature of the coolant in the second cavity is too low. After receiving the heating signal, the heater heats the coolant in the second cavity, which is conducive to the power mechanism driving the coolant.

[0017] In some embodiments, the liquid storage mechanism is further provided with a first exhaust valve and a second exhaust valve. When the first exhaust valve is opened, the first cavity is connected to the outside of the liquid storage mechanism. When the second exhaust valve is opened, the second cavity is connected to the outside of the liquid storage mechanism.

[0018] In the above embodiment, the first exhaust valve and the second exhaust valve are helpful for balancing the pressure between the first cavity and the external environment, and the pressure between the second cavity and the external environment when the power mechanism stops, thereby facilitating the coolant in the first cavity to enter the second cavity through gravity.

[0019] In some embodiments, the liquid storage mechanism is further provided with a liquid replenishing valve, which connects the first cavity with the outside when the liquid replenishing valve is opened.

[0020] In the above embodiment, external coolant can be replenished into the first cavity through the liquid replenishing valve. The provided liquid replenishing valve is conducive to manually or automatically replenishing the coolant to the first cavity after the liquid in the first cavity is consumed, which is conducive to further improving the service life of the liquid supply module.

[0021] In addition, the present application also provides a cooling system that is beneficial for improving service life.

[0022] Some embodiments of the present application provide a cooling system, which includes a cold plate, a refrigeration mechanism, and a liquid supply module as in any of the above embodiments, wherein the liquid supply module is connected to the cold plate and the refrigeration mechanism, the cold plate is connected to the refrigeration mechanism, and a power mechanism provides power for the coolant in the first cavity to flow into the cold plate and the refrigeration mechanism in sequence and flow back to the first cavity.

[0023] In the above embodiment, the liquid supply module can replenish the coolant in the coolant circulation system, which is beneficial to prolonging the service life of the cooling system.

[0024] In addition, the present application also provides an electronic device that is beneficial for improving reliability and service life.

[0025] An electronic device comprises a housing, a chip and a cooling system as in the above embodiment, wherein the chip and the cooling system are mounted on the housing, and the chip is in contact with a cold plate.

[0026] In the above embodiment, the liquid supply module can replenish the coolant in the coolant circulation system in a timely manner, which is beneficial to prolonging the service life of the cooling system, reducing the failure rate of the cooling system, and thus improving the reliability and service life of the electronic device.

[0027] The liquid supply module in the present application includes a liquid storage mechanism, a power mechanism and a one-way valve. The liquid storage mechanism is separated by a first cavity and a second cavity, the first cavity is used to replenish the second cavity with coolant, and the one-way valve is configured to be closed when the power mechanism drives the coolant in the second cavity, so that the first cavity and the second cavity are isolated when the power mechanism drives the coolant in the second cavity to circulate, which is beneficial to reduce the impact of the circulation system on the coolant in the first cavity. The one-way valve is configured to allow the coolant in the first cavity to be replenished into the second cavity when the power mechanism stops working, which is beneficial to the liquid supply module to replenish the circulating coolant, solving the problem of reduced cooling effect caused by loss of coolant during the circulation process.

[0074] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0075] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time.

From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0080] It should be recognized that the sizes and thicknesses of the components shown in the drawings are arbitrarily given for better understanding and more convenient description, and the present application is not limited to the sizes and thicknesses shown in the drawings.

[0081] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0082] The present application discloses a liquid supply module, which includes a liquid storage mechanism, a power mechanism and a one-way valve. The liquid storage mechanism is provided with a first cavity and a second cavity, and both the first cavity and the second cavity are used to contain coolant. The power mechanism is connected to the second cavity, and the power mechanism provides power for the coolant to flow out of the second cavity and flow back into the second cavity. The one-way valve is provided in the liquid storage mechanism, and the one-way valve connects the first cavity with the second cavity in one direction. The one-way valve is configured to close when the power mechanism drives the coolant in the second cavity, and allows the coolant in the first cavity to flow to the second cavity in one direction when the power mechanism stops working.

[0083] The first cavity is used to replenish the coolant in the second cavity, and the one-way valve is configured to close when the power mechanism drives the coolant in the second cavity, so that the first cavity and the second cavity are isolated when the power mechanism drives the coolant in the second cavity to circulate, which is conducive to reducing the impact of the circulation system on the coolant in the first cavity. The one-way valve is configured to allow the coolant in the first cavity to be replenished into the second cavity when the power mechanism stops working, which is conducive to the liquid supply module replenishing the circulating coolant, solving the problem of reduced cooling effect caused by loss of coolant during the circulation process.

[0084] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0085] See also Figure 1 and Figure 2An embodiment of the present application provides an electronic device 1, which includes a cooling system 1000, a housing 2000 and a chip 3000 (not shown). The chip 3000 and the cooling system 1000 are both installed in the housing 2000, and the cooling system 1000 is used to cool the chip 3000.

[0086] In some embodiments, the electronic device 1 includes a plurality of chips 3000 and a carrier for mounting the plurality of chips 3000. The carrier and the plurality of chips 3000 form a chip group 3000, and the cooling system 1000 can cool the chip group 3000. In other embodiments, the cooling system 1000 can also be used to cool other electronic components of the electronic device 1, which is not specifically limited here.

[0087] In some embodiments, the electronic device 1 may be a device such as a server, a switch, or a computer host, which are not listed here one by one.

[0088] In some embodiments, see Figure 2 and Figure 3 The cooling system 1000 is a liquid cooling type, so that the coolant can take away the heat generated by the chip 3000 during the circulation process. The cooling system 1000 includes a liquid supply module 100, a cold plate 200 and a refrigeration mechanism 300. The liquid supply module 100 is connected to the cold plate 200 and the refrigeration mechanism 300, and the cold plate 200 is connected to the refrigeration mechanism 300. The liquid supply module 100 also provides power for the coolant to flow from the liquid supply module 100 to the cold plate 200 and the refrigeration mechanism 300 in sequence and flow back to the liquid supply module 100.

[0089] In some embodiments, the cold plate 200 is in contact with the chip 3000 to exchange heat with the chip 3000 and take away the heat generated by the chip 3000, thereby realizing the cooling effect of the cooling system 1000 on the chip 3000.

[0090] It is understandable that the liquid supply module 100 is used to contain and provide cooling liquid for cooling circulation, and the cold plate 200 is provided with a pipeline for circulating the cooling liquid. The liquid supply module 100 drives the cooling liquid therein to flow into the pipeline of the cold plate 200, and the cold plate 200 contacts the chip 3000 and takes away the heat generated by the chip 3000. The cooling liquid in the pipeline of the cold plate 200 heats up after heat exchange with the chip 3000, and the heated cooling liquid flows to the refrigeration mechanism 300, and the refrigeration mechanism 300 is used to reduce the temperature of the heated cooling liquid, and the cooled cooling liquid flows back to the liquid supply module 100.

[0091] In some embodiments, the refrigeration mechanism 300 may be provided with fins for exchanging heat with air, and the refrigeration mechanism 300 may also be provided with a fan to dissipate heat from the fins, thereby reducing the temperature of the coolant in the refrigeration mechanism 300 .

[0092] In some embodiments, see Figure 4 The liquid supply module 100 includes a liquid storage mechanism 10, a power mechanism 20 and a one-way valve 30. The liquid storage mechanism 10 is provided with a first cavity 10a and a second cavity 10b, and the first cavity 10a and the second cavity 10b are both used to contain cooling liquid. The power mechanism 20 is connected to the second cavity 10b, and is used to provide power to drive the cooling liquid in the second cavity 10b to flow out of the second cavity 10b and flow back into the second cavity 10b. The one-way valve 30 is provided in the liquid storage mechanism 10, and the one-way valve 30 connects the first cavity 10a and the second cavity 10b in one direction. The one-way valve 30 is configured to close when the power mechanism 20 drives the cooling liquid in the second cavity 10b, and open when the power mechanism 20 stops working. When the one-way valve 30 is opened, the cooling liquid in the first cavity 10a is allowed to flow into the second cavity 10b, so that the cooling liquid in the second cavity 10b is replenished.

[0093] During the circulation of the coolant, the coolant in the closed pipeline vaporizes, liquefies, expands or contracts due to the effect of temperature, resulting in a small amount of coolant being lost at the connection of the pipeline, resulting in a problem of reduced cooling effect. The first cavity 10a in the present application is used to replenish the coolant for the second cavity 10b, and the one-way valve 30 is configured to be closed when the power mechanism 20 drives the coolant in the second cavity 10b to circulate, so that the first cavity 10a and the second cavity 10b are isolated when the power mechanism 20 drives the coolant in the second cavity 10b to circulate. When the coolant in the first cavity 10a does not enter the circulation system, it will not be lost at the connection of the pipeline due to the effect of temperature during the process of vaporization, liquefaction, expansion or contraction, so that it is not affected by the circulation system on the coolant in the first cavity 10a. The one-way valve 30 is configured to allow the coolant in the first cavity 10a to be replenished into the second cavity 10b when the power mechanism 20 stops working, which is beneficial for the liquid supply module 100 to replenish the circulating coolant, solving the problem of reduced cooling effect caused by loss of coolant during the circulation process.

[0094] It can be understood that the liquid storage mechanism 10 is used to contain the coolant in the cooling cycle, and the power mechanism 20 is connected to the liquid storage mechanism 10. Through the cooperation between the liquid storage mechanism 10 and the power mechanism 20, the coolant circulates in the circulation system.

[0095] In some embodiments, see Figure 4 The liquid storage mechanism 10 includes a box body 11, a cover plate 12 and a partition plate 13. The box body 11 is connected to the cover plate 12 and encloses a space for accommodating the cooling liquid. The partition plate 13 is connected to the box body 11 and is used to separate the space for accommodating the cooling liquid into a first cavity 10a and a second cavity 10b.

[0096] It can be understood that the partition 13 isolates the first cavity 10a and the second cavity 10b, so that the coolant in the second cavity 10b participates in the circulation, and the coolant in the first cavity 10a does not participate in the circulation. The coolant in the first cavity 10a is used to supplement the coolant in the second cavity 10b.

[0097] In some embodiments, please participate Figure 4 , the cover plate 12 is arranged substantially parallel to the partition plate 13. In some other embodiments, the cover body and the partition plate 13 are arranged substantially perpendicularly.

[0098] In other embodiments, the liquid storage mechanism 10 may also be a liquid storage barrel, a liquid storage bag, or the like having a first cavity 10a and a second cavity 10b, which is not specifically limited herein.

[0099] In some embodiments, see Figure 4 The first cavity 10a and the second cavity 10b are sequentially arranged along the gravity direction G. When the one-way valve 30 is opened, the coolant in the first cavity 10a enters the second cavity 10b through the one-way valve 30 due to gravity. The first cavity 10a and the second cavity 10b are sequentially arranged along the gravity direction G, which is conducive to replenishing the liquid in the first cavity 10a into the second cavity 10b, and it is not necessary to provide other liquid driving devices, which is conducive to reducing the overall occupied space of the liquid storage mechanism 10 and saving costs.

[0100] In some embodiments, see Figure 4 , along the gravity direction G, the power mechanism 20 is arranged on the side of the first cavity 10a away from the second cavity 10b, which is conducive to reducing the space occupied by the power mechanism 20 in the direction perpendicular to the gravity direction G. In addition, in extreme cases, when the coolant is lost during the circulation process and is not replenished in time, the liquid level in the second cavity 10b drops. The power mechanism 20 in the second cavity 10b is arranged on the side of the first cavity 10a away from the second cavity 10b, which is conducive to connecting the power mechanism 20 with the coolant at the bottom of the second cavity 10b, reducing the risk that the power mechanism 20 is difficult to drive the coolant to circulate after the coolant level drops due to the excessively high communication position between the power mechanism 20 and the second cavity 10b.

[0101] In some embodiments, see Figure 4The liquid storage mechanism 10 is provided with a liquid discharge port 15 connected to the second cavity 10b, and the power mechanism 20 has a first liquid end 21 and a second liquid end 22. The first liquid end 21 extends into the liquid discharge port 15 and is fixed to the liquid storage mechanism 10, and the second liquid end 22 is connected to the pipeline connected to the cold plate 200. The first liquid end 21 of the power mechanism 20 is directly fixed and connected to the liquid discharge port 15 of the liquid storage mechanism 10, and the liquid storage mechanism 10 and the power mechanism 20 are integrated, which saves the pipeline between the liquid storage mechanism 10 and the power mechanism 20, reduces the number of pipeline connections, and is conducive to reducing the risk of cooling liquid loss from the pipeline connection.

[0102] In some embodiments, the first liquid passing end 21 is an end where liquid enters, and the second liquid passing end 22 is an end where liquid exits.

[0103] In some other embodiments, the first liquid passing end 21 is a liquid outlet end, and the second liquid passing end 22 is a liquid inlet end, so that the flow directions of the entire cooling cycle are opposite.

[0104] In some embodiments, the number of the power mechanism 20 is one, which is beneficial to reducing the space occupied by the power mechanism 20, increasing the accommodation space of the liquid storage mechanism 10, and also beneficial to saving costs.

[0105] In some embodiments, there are multiple power mechanisms 20, which are connected in sequence and arranged in series, one of which is connected to the second cavity 10b of the liquid storage mechanism 10, and one of which is connected to the pipeline connected to the cold plate 200. This arrangement allows the other power mechanisms 20 to continue to operate and the circulation of the coolant to continue when one of the power mechanisms 20 fails, thereby improving the reliability of the liquid supply module 100.

[0106] In some other embodiments, there are multiple power mechanisms 20, each of which is connected to the second cavity 10b of the liquid storage mechanism 10, and each of which is connected to the pipeline connected to the cold plate 200, so that the multiple power mechanisms 20 are connected in parallel. This arrangement allows one of the power mechanisms 20 to fail while the other power mechanisms 20 can still continue to operate, and the circulation of the coolant can also continue, thereby improving the reliability of the liquid supply module 100.

[0107] In some embodiments, see Figure 5 The power mechanism 20 includes a pressure pump 23, which includes a motor 231, a wheel 232 and a partition channel 233. The motor 231 is connected to the wheel 232, and the motor 231 drives the wheel 232 to rotate in the partition channel 233 to change the pressure of the coolant in the pressure pump 23.

[0108] It can be understood that when the coolant in the second cavity 10b flows out and flows back, the pipeline and cavity of the entire cooling cycle are in a closed state, and the power mechanism 20 is connected to the second cavity 10b when driving, so the power mechanism 20 causes the pressure in the second cavity 10b to increase when starting. When the power mechanism 20 is started and the pressure in the second cavity 10b increases, a thrust is applied to the valve structure inside the one-way valve 30, so that the one-way valve 30 is closed, thereby isolating the first cavity 10a from the second cavity 10b; when the power mechanism 20 stops and the pressure in the second cavity 10b is reduced, the one-way valve 30 opens, allowing the coolant in the first cavity 10a to enter the second cavity 10b, playing the role of replenishing the coolant.

[0109] In some embodiments, see Figures 6 to 8 , a first through hole 131 is provided on the partition 13, and an annular column 14 surrounding the first through hole 131 is provided on the partition 13. The annular column 14 extends toward the second cavity 10b, and the center of the annular column 14 passes through along the gravity direction G to form a second through hole 141, and the second through hole 141 is connected with the first through hole 131. The second through hole 141 includes a first channel 1411 and a second channel 1412 sequentially arranged along the gravity direction. The one-way valve 30 includes a water stop ball 31 and a fixed cover 32. The fixed cover 32 limits the water stop ball 31 between the second channel 1412 of the annular column 14 and the fixed cover 32. The caliber of the second channel 1412 gradually decreases along the direction from the second cavity 10b to the first cavity 10a, and the water stop ball 31 cannot enter the first channel 1411 and enter the first cavity 10a through the second channel 1412. When the pressure in the second cavity 10b increases, the water stop ball 31 is pushed to block the opening of the first channel 1411 due to the pressure, and the one-way valve 30 is closed. When the pressure in the second cavity 10b decreases, the water stop ball 31 no longer blocks the opening of the first channel 1411, and the one-way valve 30 is opened.

[0110] In the embodiment where the first cavity 10a and the second cavity 10b are arranged sequentially along the gravity direction G, it is beneficial for the water stop ball 31 to fall down by gravity when the pressure in the second cavity 10b is reduced, and no longer block the opening of the annular column 14. It is also beneficial for the coolant in the first cavity 10a to enter the second cavity 10b by gravity.

[0111] In some embodiments, see Figure 4The liquid storage mechanism 10 is further provided with a first exhaust valve 16 and a second exhaust valve 17. When the first exhaust valve 16 is opened, the first cavity 10a is connected to the outside of the liquid storage mechanism 10, and when the second exhaust valve 17 is opened, the second cavity 10b is connected to the outside of the liquid storage mechanism 10. The first exhaust valve 16 and the second exhaust valve 17 are conducive to balancing the pressure of the first cavity 10a and the external environment, and the pressure of the second cavity 10b and the external environment when the power mechanism 20 stops, thereby facilitating the coolant in the first cavity 10a to enter the second cavity 10b through gravity.

[0112] In some embodiments, see Figure 4 The liquid storage mechanism 10 is also provided with a liquid replenishing valve 18. When the liquid replenishing valve 18 is opened, the first cavity 10a is connected to the outside. By providing the liquid replenishing valve 18, it is beneficial to replenish the first cavity 10a with coolant manually or automatically after the liquid in the first cavity 10a is consumed, which is beneficial to further improve the service life of the liquid supply module 100.

[0113] In some embodiments, see Figure 4 The liquid supply module 100 further includes a liquid level detector 40, which is connected to the liquid storage mechanism 10 and is at least partially located in the first cavity 10a. The liquid level detector 40 is used to detect the liquid level of the coolant in the first cavity 10a. In an embodiment with an automatic liquid replenishing mechanism, it is helpful to send liquid replenishing information to allow the automatic liquid replenishing mechanism to replenish liquid. In an embodiment of manual liquid replenishing, it is helpful to remind manual liquid replenishing in time, which is helpful to further improve the service life of the liquid supply module 100.

[0114] In some embodiments, see Fig. 9 The liquid supply module 100 also includes a temperature detector 50 and a heater 60. The temperature detector 50 is connected to the liquid storage mechanism 10 and is at least partially located in the second cavity 10b. The heater 60 is connected to the liquid storage mechanism 10 and is at least partially located in the second cavity 10b. The temperature detector 50 is used to detect the temperature in the second cavity 10b. When the temperature detector 50 detects that the temperature of the coolant in the second cavity 10b is too low, it can be judged that the ambient temperature is low, there are phenomena such as pipeline icing, and the power mechanism 20 is difficult to drive the coolant in the second cavity 10b. The temperature detector 50 outputs a heating signal when it detects that the temperature of the coolant in the second cavity 10b is too low. After receiving the heating signal, the heater 60 heats the coolant in the second cavity 10b, which is beneficial for the power mechanism 20 to drive the coolant.

[0115] In some embodiments, the cooling system 1000 further includes a controller (not shown), which is electrically connected to the power mechanism 20, the first exhaust valve 16, the second exhaust valve 17, the liquid level detector 40, the temperature detector 50, and the heater 60. The controller controls the start and stop of the power mechanism 20. When the power mechanism 20 is stopped, the controller can control the first exhaust valve 16 and the second exhaust valve 17 to open. The controller can control the liquid level detector 40 to detect the liquid level of the coolant in the first cavity 10a. The controller can control the temperature detector 50 to detect the temperature of the coolant in the second cavity 10b, and is used to receive the temperature increase signal output by the temperature detector 50. The controller transfers the received temperature increase signal to the heater 60 to control the heater 60 to heat the coolant.

[0116] In some embodiments, the controller may be a single chip microcomputer, a PLC, a control mainboard or a microcomputer, etc., which are not listed here one by one.

As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
