Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, specifically a dual-circulation liquid cooling heat dissipation device. Background Technology

[0002] Dual-circulation liquid cooling is a technology that uses two independent or coupled liquid circulation loops to achieve efficient heat dissipation. The flow of liquid in different loops separately handles the tasks of absorbing and releasing heat. Compared to single-circulation liquid cooling systems, dual-circulation liquid cooling devices are highly efficient heat dissipation systems that achieve heat transfer and dissipation through dual-circulation liquid flow. Utilizing two independent or coupled liquid circulation loops to absorb and release heat from the heat source respectively, it offers higher heat dissipation efficiency, temperature control accuracy, and system reliability compared to single-circulation liquid cooling systems. It is mainly used in high-power-density electronic devices, new energy power systems, industrial machinery, and other scenarios requiring efficient heat dissipation.

[0003] When using a dual-circulation liquid cooling heat dissipation device, its internal heat exchanger needs to be cleaned regularly. Although existing heat exchangers can be disassembled for cleaning, the bolts need to be removed. Over time, the bolts will rust, making it inconvenient to disassemble the heat exchanger. Therefore, we propose a dual-circulation liquid cooling heat dissipation device that allows for quick disassembly and assembly of the heat exchanger, making cleaning more convenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a dual-circulation liquid cooling heat dissipation device, which solves the problem of convenient disassembly and cleaning of the heat exchanger in the dual-circulation liquid cooling heat dissipation device.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a dual-circulation liquid cooling heat dissipation device, including a dual-circulation liquid cooling heat dissipation tank, a first heat dissipation pipe is connected to the outer wall of the dual-circulation liquid cooling heat dissipation tank, a second heat dissipation pipe is provided at the end of the dual-circulation liquid cooling heat dissipation tank, and a processing component is provided outside the first heat dissipation pipe. The processing component includes a disassembly and assembly component provided below the first heat dissipation pipe, and a sealing component is provided on the side of the disassembly and assembly component.

[0008] Preferably, the disassembly and assembly assembly includes a base plate disposed below the dual-circulation liquid-cooled heat sink, a vertical plate fixedly installed on the top surface of the base plate, a counter-threaded rod rotatably connected inside the vertical plate, a U-shaped frame sleeved on the outer wall of the counter-threaded rod, a tank cover fixedly installed at the end of the U-shaped frame, a rod frame slidably disposed inside the U-shaped frame, a fixing block fixedly installed on the outer wall of the dual-circulation liquid-cooled heat sink, a telescopic rod fixedly installed at the bottom of the fixing block, a heat exchanger snapped into the inside of the dual-circulation liquid-cooled heat sink, an elastic ball fixedly installed on the outer wall of the heat exchanger, and a ball groove opened inside the dual-circulation liquid-cooled heat sink.

[0009] Preferably, the sealing assembly includes a fixed plate fixedly installed on the top surface of the base plate, a sliding column fixedly installed on the side wall of the fixed plate, an inclined frame slidably provided on the outer wall of the sliding column, a sealing ring fixedly installed at the end of the inclined frame, and a limit frame slidably provided inside the sealing ring.

[0010] Preferably, the heat exchanger end is connected to the tank cover, and the elastic ball is made of elastic material and is engaged with the ball groove. Under the restriction of the connection between the heat exchanger and the tank cover, the heat exchange fluid entering the second heat dissipation pipe can exchange heat with the heat exchanger to achieve the heat dissipation effect.

[0011] Preferably, there are two U-shaped frames, symmetrically distributed around the center line of the top surface of the base plate. The two U-shaped frames moving in opposite directions can open the end of the dual-circulation liquid-cooled heat exchange tank for cleaning the heat exchanger.

[0012] Preferably, the inclined frame is inclined, and the end of the limiting frame is fixedly installed at the bottom of the dual-circulation liquid cooling tank. Under the sliding restriction of the limiting frame and the sealing ring, when the sliding column squeezes the inside of the inclined frame, it can ensure that the sealing ring is stably fitted on the outer wall of the dual-circulation liquid cooling tank.

[0013] (III) Beneficial Effects

[0014] This invention provides a dual-circulation liquid cooling heat dissipation device. It has the following beneficial effects:

[0015] (I) This dual-circulation liquid cooling heat dissipation device, when the dual-circulation liquid cooling heat dissipation tank is in use, injects hot water into the second heat dissipation pipe connected to the outer wall of the tank cover. The hot water enters the heat exchanger and flows out through another second heat dissipation pipe, achieving primary liquid cooling. Then, hot water is added to the dual-circulation liquid cooling heat dissipation tank through the first heat dissipation pipe. The cooling water surrounds the heat exchanger and exchanges heat with it, achieving secondary liquid cooling, thus achieving the dual-circulation liquid cooling heat dissipation effect. When the dual-circulation liquid cooling heat dissipation tank is in use, the heat exchanger inside needs to be cleaned regularly to improve the heat dissipation effect. At this time, rotating the opposing threaded rod causes the U-shaped frame, which is fixedly installed on the top surface of the base plate, to slide within the U-shaped frame. Under its constraint, the rotating opposing threaded rod drives the U-shaped frame fitted on its outer wall to move. The two U-shaped frames move in opposite directions, causing the tank cover fixedly installed at its end to move. When the tank lid is no longer in contact with the end of the dual-circulation liquid-cooled heat sink, the telescopic rod is activated, which pushes the fixing block upward. The fixing block drives the dual-circulation liquid-cooled heat sink upward, lifting the heat exchanger. At this time, the operator pulls the heat exchanger, causing the elastic ball to deform. The elastic ball is no longer stuck with the ball groove, and the heat exchanger can be removed from the inside of the dual-circulation liquid-cooled heat sink. The scale adhering to its outer wall and the inner wall of the dual-circulation liquid-cooled heat sink can be cleaned to ensure better heat dissipation effect of the dual-circulation liquid cooling. This structure can clean the heat exchanger and the dual-circulation liquid-cooled heat sink to improve the heat dissipation effect (the dual-circulation liquid-cooled heat sink, the first heat dissipation pipe, the second heat dissipation pipe and the heat exchanger are existing public technologies, so their principles are not fully described. Also, the equipment connection parts adapted to the dual-circulation liquid-cooled heat sink are existing public technologies, so their structure is not described).

[0016] (II) In this dual-circulation liquid cooling heat dissipation device, when the tank cover comes into contact with the dual-circulation liquid cooling heat dissipation tank, in order to avoid gaps at the connection, it is necessary to seal it. At this time, the telescopic rod is activated, which pulls the entire dual-circulation liquid cooling heat dissipation tank downward. The dual-circulation liquid cooling heat dissipation tank drives the limiting frame fixedly installed at its bottom downward. Since the inclined frame is set at an inclination and the outer wall of the sliding column slides with the inside of the inclined frame, under its restriction, the inclined frame drives the sealing ring to move away from the first heat dissipation pipe. At this time, the opposing threaded rod is rotated, so that the tank cover moves towards the dual-circulation liquid cooling heat dissipation tank and is fitted inside the sealing ring. Under the restriction of the sealing ring, the connection between the dual-circulation liquid cooling heat dissipation tank and the tank cover can be sealed. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a technical solution: a dual-circulation liquid cooling heat dissipation device, including a dual-circulation liquid cooling heat dissipation tank 1, a first heat dissipation pipe 2 connected to the outer wall of the dual-circulation liquid cooling heat dissipation tank 1, a second heat dissipation pipe 3 at the end of the dual-circulation liquid cooling heat dissipation tank 1, and a processing component 4 disposed outside the first heat dissipation pipe 2. The processing component 4 includes a disassembly and assembly component 41 disposed below the first heat dissipation pipe 2, a sealing component 43 disposed on the side of the disassembly and assembly component 41, and a base plate 416 disposed below the dual-circulation liquid cooling heat dissipation tank 1. A sealing component 43 is fixedly installed on the top surface of the base plate 416. A vertical plate 411 has a rotatably connected opposing threaded rods 412 inside. A U-shaped frame 413 is fitted on the outer wall of the opposing threaded rods 412. A tank cover 414 is fixedly installed at the end of the U-shaped frame 413. A rod frame 415 is slidably installed inside the U-shaped frame 413. A fixing block 418 is fixedly installed on the outer wall of the dual-circulation liquid-cooled heat sink 1. A telescopic rod 417 is fixedly installed at the bottom of the fixing block 418. A heat exchanger 419 is snapped into the inside of the dual-circulation liquid-cooled heat sink 1. An elastic ball 420 is fixedly installed on the outer wall of the heat exchanger 419. A ball groove 420 is opened inside the dual-circulation liquid-cooled heat sink 1. 21. The sealing assembly 43 includes a fixing plate 431 fixedly installed on the top surface of the base plate 416. A sliding column 432 is fixedly installed on the side wall of the fixing plate 431. An inclined frame 433 is slidably provided on the outer wall of the sliding column 432. A sealing ring 434 is fixedly installed at the end of the inclined frame 433. A limit bracket 435 is slidably provided inside the sealing ring 434. The end of the heat exchanger 419 is connected to the tank cover 414. The elastic ball 420 is made of elastic material and is engaged with the ball groove 421. Under the restriction of the connection between the heat exchanger 419 and the tank cover 414, the heat exchange fluid entering the second heat dissipation pipe 3 can make the heat exchanger... 419 heat exchange is used to achieve heat dissipation. There are two U-shaped frames 413, which are symmetrically distributed around the center line of the top surface of the base plate 416. The two U-shaped frames 413 moving in opposite directions can open the end of the double-circulation liquid-cooled heat sink 1 to clean the heat exchanger 419. The inclined frame 433 is set at an inclination. The end of the limiting frame 435 is fixedly installed at the bottom of the double-circulation liquid-cooled heat sink 1. Under the sliding restriction of the limiting frame 435 and the sealing ring 434, when the sliding column 432 squeezes the inside of the inclined frame 433, it can ensure that the sealing ring 434 is stably fitted on the outer wall of the double-circulation liquid-cooled heat sink 1.

[0026] In use, when the dual-circulation liquid-cooled heat exchange tank 1 is in use, hot water is injected into the second heat exchange pipe 3 connected to the outer wall of the tank cover 414. The hot water enters the heat exchanger 419 and flows out to the other second heat exchange pipe 3, achieving primary liquid cooling. Then, hot water is added into the dual-circulation liquid-cooled heat exchange tank 1 through the first heat exchange pipe 2. The cooling water surrounds the heat exchanger 419 and exchanges heat with it, achieving secondary liquid cooling. This achieves the dual-circulation liquid cooling effect. When the dual-circulation liquid-cooled heat exchange tank 1 is in use, the heat exchanger 419 inside needs to be cleaned regularly to improve the heat dissipation effect. At this time, rotating the opposing threaded rod 412 causes the U-shaped frame 413 to connect with the top surface of the base plate 416. The fixedly installed rod 415 slides on its outer wall. Under its constraint, the rotating opposing threaded rod 412 drives the U-shaped frame 413 sleeved on its outer wall to move. The two U-shaped frames 413 move in opposite directions, driving the tank cover 414 fixedly installed at its end to move. The tank cover 414 no longer contacts the end of the double-circulation liquid-cooled heat sink 1. At this time, the telescopic rod 417 is activated, which pushes the fixing block 418 upward. The fixing block 418 drives the double-circulation liquid-cooled heat sink 1 to move upward, lifting the heat exchanger 419. At this time, the operator pulls the heat exchanger 419, causing the elastic ball 420 to deform. The elastic ball 420 is no longer engaged with the ball groove 421, and the heat exchanger 419 can be lifted. 9. Remove the heat exchanger 419 from the inside of the dual-circulation liquid-cooled heat sink 1 and clean the scale adhering to its outer wall and inner wall to ensure better heat dissipation of the dual-circulation liquid cooling system. This structure can clean the heat exchanger 419 and the dual-circulation liquid-cooled heat sink 1 to improve the heat dissipation effect (the dual-circulation liquid-cooled heat sink 1, the first heat dissipation pipe 2, the second heat dissipation pipe 3, and the heat exchanger 419 are existing known technologies, so their principles are not fully described. Similarly, the equipment connection components adapted to the dual-circulation liquid-cooled heat sink 1 are existing known technologies, so their structures are not described). When the tank cover 414 contacts the dual-circulation liquid-cooled heat sink 1, to avoid gaps at the connection point, it is necessary to... For sealing, the telescopic rod 417 is activated, which pulls the entire dual-circulation liquid-cooled heat sink 1 downward. The dual-circulation liquid-cooled heat sink 1 drives the limiting frame 435 fixed at its bottom downward. Since the inclined frame 433 is inclined and the outer wall of the sliding column 432 slides with the inside of the inclined frame 433, under its restriction, the inclined frame 433 drives the sealing ring 434 to move away from the first heat sink 2. At this time, the opposing threaded rod 412 is rotated, causing the can cover 414 to move towards the dual-circulation liquid-cooled heat sink 1 and be fitted inside the sealing ring 434. Under the restriction of the sealing ring 434, the connection between the dual-circulation liquid-cooled heat sink 1 and the can cover 414 can be sealed.
