Description

Technical Field

[0001] The present invention relates to the technical field of cooling electronic equipment, and in particular to a cooling device for electronic equipment. Background Art

[0002] As the performance of electronic equipment continues to improve, the assembly density of internal components is also gradually increasing. This high-density design significantly increases the total heat consumption and local heat flux density generated by electronic equipment during operation. At present, traditional heat dissipation methods, such as natural heat dissipation and air cooling, can no longer effectively meet the heat dissipation needs of modern high-performance electronic equipment. Therefore, liquid cooling technology has gradually become a feasible and effective heat dissipation solution. Liquid cooling technology can transfer heat from heating elements to heat dissipation devices through the high thermal conductivity and good heat conduction ability of liquid, thereby achieving thermal management. Compared with traditional heat dissipation methods, liquid cooling systems can handle higher heat flux densities and ensure system stability and reliability.

[0003] The liquid cooling plate and electronic equipment disclosed in the existing publication number CN115297693A include a cooling body, a leak-proof shell, a liquid inlet pipe and a liquid outlet pipe; the cooling body includes a base plate and a cover plate arranged on the base plate, a flow channel is provided in an area on the base plate corresponding to the cover plate, the flow channel and the cover plate form a cooling space for the flow of coolant, and a liquid inlet and a liquid outlet communicating with the cooling space are provided on the cover plate; at least a part of the area of ​​the base plate and the leak-proof shell form a leak-proof cavity, and the cover plate and the cooling space are both located in the leak-proof cavity; one end of the liquid inlet pipe is connected to the liquid inlet, one end of the liquid outlet pipe is connected to the liquid outlet, and the other end of the liquid inlet pipe and the other end of the liquid outlet pipe both pass through the leak-proof shell and are located outside the leak-proof shell.

[0004] Although the above technical solution can reduce the probability of coolant falling on electronic devices near the liquid cooling plate and has the advantage of improving the anti-leakage performance of the liquid cooling plate, in the prior art, although the liquid cooling system quickly removes heat from the heat source by circulating the coolant in the heat dissipation channel, when the coolant passes through the channel, the coolant in the front half of the channel has already undergone a certain degree of heat exchange with the heat source and removed part of the heat. As the coolant continues to flow, its temperature gradually increases. Therefore, when flowing through the second half of the channel, its heat dissipation capacity is significantly reduced compared to the first half, resulting in the coolant in the second half being unable to remove the remaining heat as effectively as in the first half, thereby reducing the overall heat dissipation efficiency. In addition, due to the reduction in temperature difference, the heat exchange efficiency between the coolant in the second half and the channel wall will also be reduced accordingly, further limiting the improvement in the heat dissipation effect. Therefore, a new type of cooling device for electronic equipment is needed to solve the above problems. Summary of the invention

[0040] Reference Figure 2-Figure 8 The housing 1 is provided with a compensating cooling mechanism 2 having the same number as the coolant pipes 11 and corresponding to each other. The compensating cooling mechanism 2 is used to store the coolant and to supplement the coolant to the middle part of the middle pipe 112;

[0041] Specifically, the compensating cooling mechanism 2 includes a liquid storage tank 21 arranged in the shell 1, a branch pipe 22 connected to the liquid inlet pipe 14, a connecting pipe 23 for connecting the liquid storage tank 21 and the branch pipe 22, a liquid discharge pipe 24 connected to the liquid storage tank 21, and an arc-shaped connecting plate 25 connected to the liquid discharge pipe 24. At least three groups of nozzles 26 are arranged on the arc-shaped connecting plate 25. The middle sealing sleeve of the middle section pipe 112 is provided with a sealing ring 27. The nozzle 26 penetrates the sealing ring 27 and is inserted into the middle section pipe 112. By replenishing the coolant in the middle part of the middle section pipe 112, the new coolant in the middle can effectively reduce the temperature of the coolant in the rear half without heat exchange with the heat source, so that it maintains a high heat exchange capacity, thereby improving the overall heat dissipation efficiency.

[0042] Among them, the inner wall of the liquid storage tank 21 is made of stainless steel, which can enhance the thermal insulation performance of the coolant.

[0043] It is worth mentioning that a channel 251 is opened in the arc-shaped connecting plate 25, and three groups of nozzles 26 are connected to the channel 251. Under the transportation of the pump 12, the coolant passes through the branch pipe 22, the connecting pipe 23, the liquid storage tank 21 and the discharge pipe 24 in sequence, and enters the channel 251 and is sprayed into the middle part of the middle section pipe 112 through the nozzle 26, thereby entering the middle section pipe 112 to replenish the coolant. The coolant can be quickly dispersed into the middle section pipe 112 by spraying, so that the coolant can evenly cover the rear half of the middle section pipe 112 and the rear section pipe 113, thereby improving the efficiency of flow and heat exchange.

[0044] Reference Figure 6-Figure 7 The liquid storage tank 21 includes a liquid storage section 211, a liquid inlet section 212 and a tapered section 213;

[0045] Specifically, one end of the liquid storage section 211 is threadedly connected to the liquid inlet section 212, and the other end of the liquid storage section 211 is threadedly connected to the conical section 213. A spiral groove 2132 is provided in the conical section 213. The design of the spiral groove 2132 enables the coolant to generate a rotational motion during the flow process, thereby helping to increase the flow speed of the coolant and improve the heat exchange efficiency.

[0046] Among them, a liquid inlet 2121 is provided at one end of the liquid inlet section 212 away from the liquid storage section 211, and the liquid inlet 2121 is connected to the connecting pipe 23. A liquid outlet 2131 is provided at one end of the conical section 213 away from the liquid storage section 211, and the liquid outlet 2131 is connected to the drain pipe 24. The coolant enters the liquid storage section 211 through the liquid inlet 2121 for storage, and is transported to the drain pipe 24 through the liquid outlet 2131.

[0047] Reference Fig.12 , a supporting component 4 is provided outside the liquid storage section 211;

[0048] Specifically, the support component 4 includes a support rod 41 fixed in the shell 1 and a clamp 42 arranged on the support rod 41. The clamp 42 is sleeved outside the liquid storage section 211. The support rod 41 and the clamp 42 are used to support the entire liquid storage tank 21 by utilizing the cooperation of the support rod 41 and the clamp 42.

[0049] Further, see Figure 6 as well as Figure 9-12 , a temperature control mechanism 3 is provided in the liquid storage section 211;

[0050] Specifically, the temperature control mechanism 3 includes an inclined plate 31 fixed in the liquid storage section 211, an opening 311 provided on the inclined plate 31, a baffle 32 rotatably arranged in the opening 311, a hinge block 34 movably arranged on the baffle 32, a connecting rod 35 rotatably connected to the hinge block 34, a piston block 36 fixedly connected to the connecting rod 35, and a sleeve rod 37 fixed at the bottom of the liquid storage section 211, the piston block 36 is slidably arranged in the sleeve rod 37, the connecting rod 35 penetrates the liquid storage section 211 and is inserted in the sleeve rod 37, and the end of the sleeve rod 37 away from the liquid storage section 211 is connected with an air pipe 38, and the air pipe 38 is filled with a gaseous refrigerant, and the gaseous refrigerant can be carbon dioxide, and the end of the air pipe 38 away from the liquid storage section 211 penetrates to the outside of the shell 1 , and a heat-conducting copper block 39 is fixed. When the temperature of the electronic equipment is high, the temperature of the local area of ​​the electronic equipment is conducted by using the heat-conducting copper block 39. When the temperature of the local area of ​​the electronic equipment is high, the corresponding heat-conducting copper block 39 conducts the high temperature, so that the gaseous refrigerant in the corresponding air pipe 38 is heated. As the temperature rises, the pressure of the gaseous refrigerant increases, thereby pushing the piston block 36 to move upward in the sleeve rod 37, and through the cooperation of the connecting rod 35 and the hinge block 34, the baffle 32 is pushed to rotate, and the opening 311 is opened to release the coolant, so that the coolant passes through the tapered section 213, the drain pipe 24, the arc-shaped connecting plate 25 and the nozzle 26 into the middle part of the middle section pipe 112 for compensatory cooling.

[0051] Among them, a slider 341 is fixed on the hinge block 34, and a sliding groove 342 is provided on the baffle 32 for the slider 341 to slide in a limited position. When the connecting rod 35 is pushed upward, the hinge block 34 can control the rotation of the baffle 32 under the sliding cooperation of the slider 341 and the sliding groove 342.

[0052] By setting the temperature control mechanism 3, when the overall temperature of the electronic device is normal, the coolant can be stored in the liquid storage section 211. When the temperature of the local area of ​​the electronic device rises, the baffle 32 is controlled to rotate, and the middle part of the middle section tube 112 is supplemented with coolant, thereby improving the heat dissipation efficiency of the coolant in the rear half of the middle section tube 112 and the rear section tube 113. By timely supplementing the coolant to lower the temperature of the electronic device, it is possible to effectively avoid performance degradation or hardware damage caused by overheating. In addition, the temperature of the local area of ​​the electronic device is detected and conducted by the heat-conducting copper block 39, and the coolant can be supplemented according to demand, thereby improving the utilization efficiency of resources.

[0053] Reference Fig.11 The baffle 32 is rotatably connected to the opening 311 through the rotating shaft 33. Both ends of the rotating shaft 33 are provided with torsion springs 331. The torsion springs 331 are wound around the two ends of the rotating shaft 33. The two ends of the torsion spring 331 are respectively welded to the opening 311 and the baffle 32. Through the setting of the torsion spring 331, the baffle 32 can be controlled to reset and close after the heat dissipation in the high-temperature area of ​​the electronic equipment is completed.

[0054] A limit strip 312 is fixed below one side of the inclined plate 31 close to the liquid inlet section 212 , and the limit strip 312 abuts against the baffle 32 . The limit strip 312 is used to limit the baffle 32 , so as to facilitate the resetting of the baffle 32 .

[0055] Reference Figure 9-10 The liquid storage section 211 is provided with a hole for the connecting rod 35 to be inserted, and two sets of sealing gaskets 351 for sealing the hole are fixed on the connecting rod 35. When the connecting rod 35 pushes the baffle 32 upward, the sealing gasket 351 located below the connecting rod 35 can seal the bottom of the hole, and when the connecting rod 35 is reset, the sealing gasket 351 located above the connecting rod 35 can seal the top of the hole.

[0056] Reference Fig.12 , a heat conducting mechanism 5 is provided at the bottom of the housing 1;

[0057] Specifically, the heat conducting mechanism 5 includes a plurality of fins 51 fixed to the bottom of the shell 1 and a heat conducting rod 52 passing through the plurality of fins 51. The fins 51 and the heat conducting rod 52 are in contact with the heat source of the electronic device, and the bottom of the heat conducting copper block 39 is flush with the bottom of the fins 51, so as to conduct heat of the electronic device.

[0058] The working principle of the cooling device of an electronic device of the present invention is as follows: firstly, the housing 1 is installed at the heat source of the electronic device, and the fins 51 and the heat-conducting copper block 39 are in contact with the heat source, and then the pump 12 is started to transmit the coolant in the external coolant tank, so that the coolant passes through the liquid inlet pipe 14 and the liquid delivery pipe 13 in sequence and enters the coolant pipe 11, and the coolant entering the coolant pipe 11 is cooled in sequence through the front section pipe 111, the middle section pipe 112 and the rear section pipe 113, and then discharged to the external radiator through the liquid outlet pipe 15, and finally enters the coolant tank through the pipeline to realize circulation;

[0059] During the process of the coolant being transmitted through the liquid inlet pipe 14, a part of the coolant is transmitted through the branch pipe 22, and enters the liquid storage section 211 through the connecting pipe 23, the liquid inlet 2121, and the liquid inlet section 212 in sequence. When the temperature of a local area of ​​the electronic equipment is high, the corresponding heat-conducting copper block 39 conducts the high temperature, and the gaseous refrigerant in the corresponding air pipe 38 is heated during the conduction process. As the temperature rises, the pressure of the gaseous refrigerant increases, thereby pushing the piston block 36 to move upward in the sleeve rod 37, and at the same time controlling The connecting rod 35 moves upward, and the baffle 32 rotates around the rotating shaft 33 by sliding cooperation of the hinge block 34, the slider 341 and the slide groove 342, thereby opening the opening 311 to release the coolant. At this time, the coolant enters the drain pipe 24 through the tapered section 213 and the liquid outlet 2131, and enters the channel 251 through the drain pipe 24, and is finally sprayed into the middle part of the middle section pipe 112 through the nozzle 26, and enters the middle section pipe 112 to replenish the coolant and achieve compensatory cooling.
