As a core heat dissipation component that is in direct contact with the heat source, the performance of liquid cooling plates directly determines the working stability and service life of heat-generating components, and has become a key research direction in the current heat dissipation technology field.

[0003] Liquid cooling pipes and heat exchange plates are the core heat exchange elements. When the liquid cooling pipes and heat exchange plates become clogged, aged, or damaged due to long-term use, they need to be repaired or replaced. In existing liquid cooling plates, the liquid cooling pipes and heat exchange plates are usually fixedly connected to the mounting frame, which makes it inconvenient to quickly replace the liquid cooling pipes and heat exchange plates, thus affecting the cooling efficiency.

[0004] To address this, a high-strength thin-walled stamped liquid cooling plate is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength, thin-walled, stamped liquid cooling plate that can solve the problem that when existing liquid cooling pipes and heat exchange plates, which are the core heat exchange elements, become clogged, aged, or damaged due to long-term use, they need to be repaired or replaced. In existing liquid cooling plates, the liquid cooling pipes and heat exchange plates are usually fixedly connected to the mounting frame, which makes it inconvenient to quickly replace the liquid cooling pipes and heat exchange plates, thus affecting the cooling efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength thin-walled stamped liquid-cooled plate, comprising a liquid-cooling assembly, wherein a heat exchange plate is provided on the top of the liquid-cooling assembly, and a quick-release assembly is provided between the heat exchange plate and the liquid-cooling assembly; the liquid-cooling assembly includes a mounting frame made of high-strength steel, and a serpentine tube is provided inside the mounting frame, with external connecting pipes fixedly connected to both ends of the serpentine tube; a first arc-shaped groove is provided on both sides of the top of the mounting frame, and the external connecting pipe is disposed inside the first arc-shaped groove and tightly fitted with the first arc-shaped groove; a fixing plate is bolted to both sides of the top of the mounting frame, and a second arc-shaped groove is provided at the bottom of the fixing plate, and the second arc-shaped groove cooperates with the first arc-shaped groove.

[0015] 1. This application sets up a liquid cooling component, and the mounting frame is made of high-strength steel. Compared with traditional aluminum alloy or plastic frames, it significantly improves the structural strength and deformation resistance while ensuring the thin-walled and lightweight characteristics. It can withstand the cooling fluid circulation pressure, equipment vibration and installation load for a long time, and avoid the displacement of liquid cooling pipes caused by frame deformation. At the same time, the first arc groove and the second arc groove cooperate to form a wrap-around fixation for the outer pipes at both ends of the serpentine tube, thereby preventing the serpentine tube from vibrating and shifting. In addition, the serpentine tube can be quickly removed by disassembling the fixing plate, thus taking into account both the fixation reliability and maintenance convenience.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A high-strength thin-walled stamped liquid-cooled plate includes a liquid-cooling assembly 1, a heat exchange plate 2 on the top of the liquid-cooling assembly 1, and a quick-release assembly 3 between the heat exchange plate 2 and the liquid-cooling assembly 1. The liquid-cooling assembly 1 includes a mounting frame 101 made of high-strength steel. A serpentine tube 102 is provided inside the mounting frame 101, and external pipes 103 are fixedly connected to both ends of the serpentine tube 102. A first arc-shaped groove 104 is provided on both sides of the top of the mounting frame 101. The external pipes 103 are located inside the first arc-shaped grooves 104 and are tightly fitted with the first arc-shaped grooves 104. Fixing plates 105 are bolted to both sides of the top of the mounting frame 101. A second arc-shaped groove 106 is provided at the bottom of the fixing plate 105 and is used in conjunction with the first arc-shaped groove 104.

[0026] In this embodiment: By setting up the liquid cooling assembly 1, the mounting frame 101 is made of high-strength steel, possessing high rigidity and deformation resistance. Its function is to provide stable frame support for the entire liquid cooling assembly 1, fix the position of internal components such as the serpentine tube 102 and the base plate 7, and resist coolant circulation pressure, equipment vibration, and external installation loads, preventing displacement or leakage of the serpentine tube 102 due to frame deformation, thus ensuring structural stability for long-term use. The serpentine tube 102 is the core heat exchange element of the liquid cooling assembly 1. The curved serpentine structure increases the contact area with the heat exchange zone, and its function is to circulate coolant. When the coolant flows inside the tube, it exchanges heat with the external heat exchange plate 2 and the thermally conductive silicone pad 6 through the tube wall, efficiently carrying away the heat from the heat-generating components, achieving heat dissipation and cooling. The serpentine design slows down the coolant flow rate and extends the cooling range. The extended heat exchange time and improved heat dissipation efficiency are achieved through the external pipe 103, which serves as the connection interface between the liquid cooling plate and the external cooling system (such as a water tank, water pump, or radiator). Its function is to establish a circulation path for the coolant and, through compatibility with external pipes, ensure stable coolant flow and continuity of the heat dissipation system. The first arc groove 104 and the second arc groove 106 can initially position and fix the external pipe 103, limiting its displacement in the horizontal and vertical directions and preventing loosening of the connection between the external pipe 103 and the serpentine pipe 102 due to vibration. This provides a reference for the subsequent secondary fixing of the fixing plate 105. The fixing plate 105 is fixed to the top two sides of the mounting frame 101 by bolting. Its function is to form a wrap-around clamp on the external pipe 103, further strengthening the fixing effect of the external pipe 103 and preventing it from vibrating, shifting, or falling off.

[0027] Specifically, such as Figure 5 As shown, the quick-release assembly 3 includes a connecting block 301, which is fixedly connected to both sides of the bottom of the heat exchange plate 2. The top of the fixing plate 105 is provided with a connecting groove 4, and the connecting block 301 is used in conjunction with the connecting groove 4.

[0028] Specifically, such as Figure 5 As shown, an installation groove 5 is provided on the inner side of the connecting groove 4. A first inclined block 302 is provided inside the installation groove 5. A second inclined block 303 is fixedly connected to the surface of the connecting block 301 and the second inclined block 303 cooperates with the first inclined block 302.

[0029] Specifically, such as Figure 5 As shown, movable rods 304 extend through the interior of both sides of the fixed plate 105, and the movable rods 304 extend into the interior of the mounting groove 5 and are fixedly connected to the first inclined block 302.

[0030] Specifically, such as Figure 5 As shown, a return spring 305 is sleeved on one end of the moving rod 304 located inside the mounting groove 5. The two ends of the return spring 305 are fixedly connected to the inner wall of the mounting groove 5 and the first inclined block 302, respectively.

[0031] In this embodiment: by setting the quick-release assembly 3, the connecting block 301 can be inserted into the connecting groove 4 at the top of the fixing plate 105, so that the heat exchange plate 2 and the liquid cooling assembly 1 are initially positioned, ensuring that the heat exchange plate 2 can be accurately installed above the liquid cooling assembly 1, and ensuring the accuracy of their positions. The mounting groove 5 is used to install the first inclined block 302, providing the first inclined block 302 with room to move within the groove, thereby achieving engagement with the second inclined block 303. The first inclined block 302 is set inside the mounting groove 5 and can engage with the second inclined block 303 on the connecting block 301. When the connecting block 301 is inserted into the connecting groove... At time 4, the first inclined block 302 can move into the mounting groove 5 under the action of the second inclined block 303. The reset spring 305 can provide a reset force for the first inclined block 302. When the connecting block 301 is inserted into place, the first inclined block 302 will be reset under the elastic force of the reset spring 305, thereby blocking and limiting the second inclined block 303. The moving rod 304 is fixedly connected to the first inclined block 302. By pulling the moving rod 304, the first inclined block 302 can be moved in the mounting groove 5, thereby releasing the locking state between the first inclined block 302 and the second inclined block 303, thus facilitating the disassembly of the heat exchange plate 2.

[0032] Specifically, such as Figure 2 As shown, a thermally conductive silicone pad 6 is fixedly bonded to the bottom of the heat exchange plate 2, and the bottom of the thermally conductive silicone pad 6 is in close contact with the surface of the serpentine tube 102.

[0033] Specifically, such as Figure 2 As shown, a base plate 7 is fixedly connected to the bottom of the mounting frame 101. The top of the base plate 7 is in contact with the top of the serpentine tube 102. The base plate 7 is made of aerogel material.

[0034] Specifically, such as Figure 5 As shown, a pull plate 8 is fixedly connected to the outside of the moving rod 304, and the surface of the pull plate 8 is coated with an anti-slip material.

[0035] In this embodiment: With the above settings, the thermally conductive silicone pad 6 is located between the bottom of the heat exchange plate 2 and the serpentine tube 102. It can fill the microscopic gap between the two contact surfaces through its own elasticity, eliminate the air insulation layer, significantly reduce thermal resistance, and improve the heat transfer efficiency from the heat exchange plate 2 to the serpentine tube 102. The base plate 7 acts as a thermal insulation barrier. It can use the extremely low thermal conductivity of aerogel to block the heat loss from outside the mounting frame 101 into the serpentine tube 102, ensuring that the coolant only absorbs the heat of the target heat-generating component. At the same time, the lightweight properties of aerogel material can provide structural support without increasing the overall weight of the liquid cooling plate, which meets the requirements of thin-wall design. The anti-slip pull plate 8 can increase the operating contact area of ​​the moving rod 304, allowing the operator to pull the moving rod 304 with less effort, and facilitate the quick release of the locking state of the quick-release assembly 3.

[0036] Working principle: First, the serpentine tube 102 is placed inside the high-strength steel mounting frame 101, so that the outer connecting pipes 103 at both ends of the serpentine tube 102 are correspondingly embedded in the first arc-shaped grooves 104, ensuring that the outer connecting pipes 103 and the first arc-shaped grooves 104 are tightly fitted. Then, the fixing plate 105 is bolted to the top of the mounting frame 101, so that the second arc-shaped groove 106 at the bottom of the fixing plate 105 is aligned with the first arc-shaped groove 104, and the outer connecting pipes 103 are clamped in opposite directions, completing the fixing of the serpentine tube 102. The aerogel base plate 7 at the bottom of the inner side of the mounting frame 101 will naturally contact the bottom of the serpentine tube 102, forming a support and heat insulation barrier. Then, align the heat exchange plate 2 with the fixing plate 105, aligning the connecting blocks 301 on both sides of the bottom of the heat exchange plate 2 with the connecting groove 4 on the top of the fixing plate 105. Press the heat exchange plate 2 down. During the insertion of the connecting blocks 301 into the connecting groove 4, the second inclined block 303 on the surface of the connecting block 301 will press the first inclined block 302 in the mounting groove 5, forcing the first inclined block 302 to compress the return spring 305 and move into the mounting groove 5. When the connecting block 301 is fully inserted into the connecting groove 4, the return spring 305 will push the first inclined block 302 back to its original position, causing the first inclined block 302 to engage with the inclined surface of the second inclined block 303, thereby... Lock the connecting block 301 into the connecting groove 4 to complete the installation of the heat exchange plate 2. At this time, the thermally conductive silicone pad 6 will be tightly adhered to the surface of the serpentine tube 102 due to pressure. Finally, connect the outer pipe 103 to the external coolant circulation system (water tank, water pump, etc.) to form a closed loop. Then, fix the top of the heat exchange plate 2 to the heating element to complete the overall installation. During use, the heat generated by the heating element will be transferred to the heat exchange plate 2, and then conducted to the thermally conductive silicone pad 6 at the bottom. The thermally conductive silicone pad 6 eliminates contact gaps and efficiently transfers heat to the surface of the serpentine tube 102, avoiding the heat caused by air insulation. Due to thermal resistance loss, the coolant flowing inside the serpentine tube 102 absorbs heat and then flows into the external cooling system through the outer tube 103 to dissipate heat. The cooled coolant flows back to the serpentine tube 102, forming a continuous heat dissipation cycle. If the heat exchange plate 2 needs to be replaced, pull the anti-slip pull plate 8 to move the moving rod 304 outward. The moving rod 304 will simultaneously pull the first inclined block 302 to compress the reset spring 305, causing the first inclined block 302 to separate from the second inclined block 303 and release the lock. Then, lift the heat exchange plate 2 upward, and the connecting block 301 will come out of the connecting groove 4. The old heat exchange plate 2 can then be removed, and the new heat exchange plate 2 can be installed.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
