Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plates, and in particular to a liquid cooling plate with a double-sided heat dissipation structure. Background Technology

[0002] Liquid cooling plates are a widely used cooling technology for high-power electronic devices such as battery packs, electric vehicles, and data centers. Their main function is to use flowing coolant to remove heat generated inside the device, maintaining the system temperature within a safe operating range and preventing overheating that could lead to performance degradation or damage.

[0003] Existing technologies, such as the invention with publication number CN116231216A, disclose a liquid cooling plate for automotive power batteries. This patent uses a heat sink with a serpentine flow channel inside. Both ends of the serpentine flow channel extend to the outside of the heat sink, and each end of the serpentine flow channel has a connector. Both connectors are fixedly connected to the sides of the heat sink. A positioning component is provided on the outside of the heat sink, and connecting components are provided on the outside of the two connectors. The positioning component includes a fixed post located inside the heat sink, and a movable post sleeved on the outer wall of the fixed post. The movable post extends to the outside of the heat sink, and a first abutment block is fixedly connected to one side of the outer wall of the movable post. An mounting piece is fixedly connected to the side of the movable post away from the first abutment block. This automotive power battery liquid cooling plate can be installed and fixed without the need for external tools. The installation steps are simple, achieving tool-free installation, making operation more convenient and highly practical.

[0004] The inventors discovered in daily use that existing liquid cooling plates can only dissipate heat from one side of the battery pack. This prevents effective heat dissipation from the other side, causing heat to accumulate inside the battery pack and leading to overheating. This affects battery performance and lifespan. The inability to dissipate heat from both sides results in uneven temperature distribution within the battery pack, with some batteries potentially overheating while others remain cool. This leads to a decline in overall battery pack performance, especially under high power or fast charging conditions. Overheated batteries may experience capacity decay or damage. A single-sided cooling design is insufficient to effectively manage the battery pack temperature, necessitating additional active cooling measures (such as air cooling or an additional liquid cooling system) to assist in heat dissipation. This increases the complexity, cost, and weight of the system.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies.

[0007] To solve the above-mentioned technical problems, this utility model provides a liquid cooling plate with a double-sided heat dissipation structure, comprising: a liquid cooling plate body, a liquid cooling pipe installed inside the liquid cooling plate body, auxiliary structures on both sides of the liquid cooling plate body, the auxiliary structures including two sliding grooves, both of which are formed in the liquid cooling plate body, a plurality of sliders slidably connected to the inner wall of the sliding grooves, fixing plates fixedly connected to the upper and lower sides of the sliders, a limiting plate fixedly connected to the end of the fixing plate away from the slider, a plurality of heat dissipation strips fixedly connected to both sides of the limiting plate, and a screw threadedly connected to the inner wall of the fixing plate, the screw abutting against the liquid cooling plate body.

[0008] The effect achieved by the above components is as follows: when it is necessary to fix the battery pack, the screw is rotated to loosen it and separate the screw from the liquid cooling plate body. Then the slider is pulled to move it. The slider slides on the inner wall of the groove. The slider drives the fixing plate to move. The fixing plate drives the screw to move. The fixing plate drives the limiting plate to move. Then the limiting plate squeezes the battery pack. The heat dissipation strip can also increase the friction between the battery pack and the limiting plate.

[0009] Preferably, a plurality of handles are fixedly connected to the arc surface of the screw, and the plurality of handles are evenly distributed on the screw.

[0010] The effect achieved by the above components is that when it is necessary to rotate the screw, the handle can be rotated directly, and the handle drives the screw to rotate, making it more convenient to rotate the screw.

[0011] Preferably, a limiting rod is fixedly connected inside the groove, and the limiting rod is slidably connected to the slider.

[0012] The effect achieved by the above components is that the limiting rod can limit the slider, preventing the slider from deviating when sliding on the inner wall of the slide rail, thus improving the stability of the slider sliding.

[0013] Preferably, the heat dissipation strip is an aluminum strip, and several heat dissipation strips are evenly distributed on the limiting plate.

[0014] The effects achieved by the above components are: aluminum material can increase heat dissipation efficiency, and aluminum material has strong thermal conductivity.

[0015] Preferably, the arc surface of the liquid cooling pipe is provided with a heat dissipation structure, the heat dissipation structure includes a fixed pipe, the fixed pipe is fixedly connected to the liquid cooling pipe, four connecting rings are fixedly connected to the arc surface of the fixed pipe, a connecting pipe is slidably connected to the inner wall of the connecting ring, a retaining ring is fixedly connected to the arc surface of the connecting pipe, a retaining groove is opened on the inner wall of the connecting ring, the retaining groove engages with the retaining ring, heat dissipation pipes are installed inside the plurality of limiting plates, and two flexible hoses are fixedly connected between two adjacent heat dissipation pipes, the flexible hoses are fixedly connected to the connecting pipe.

[0016] The effect achieved by the above components is as follows: when the battery pack needs to be cooled, the liquid cooling pipe delivers coolant to the fixed pipe, then the fixed pipe delivers coolant to the connecting pipe, then the connecting pipe delivers coolant to the hose, then the coolant enters the heat dissipation pipe for circulation, then the limiting plate can dissipate heat from the battery pack, and then after the cooling pipe has flowed once, it enters the connecting pipe and then enters the fixed pipe for return.

[0017] Preferably, the hose has a circular cross-section and is made of plastic.

[0018] The effect achieved by the above components is that the plastic tubing material is relatively soft, has strong plasticity, and is also cheaper, which can reduce the manufacturing cost of the hose.

[0019] Preferably, a sealing sleeve is fixedly connected inside the connecting ring, and the sealing sleeve is a rubber sleeve.

[0020] The effect achieved by the above components is that the sealing sleeve can increase the sealing between the connecting ring and the connecting pipe, and prevent leakage when the connecting ring and the connecting pipe are connected.

[0021] Compared with related technologies, the liquid cooling plate with a double-sided heat dissipation structure provided by this utility model has the following beneficial effects:

[0022] This invention provides a liquid cooling plate with a double-sided heat dissipation structure. By incorporating an auxiliary structure, it addresses the limitation of existing liquid cooling plates that can only dissipate heat from one side of the battery pack. This prevents effective heat release from the other side, leading to heat accumulation within the battery pack and overheating, impacting battery performance and lifespan. The inability to dissipate heat from both sides also results in uneven internal temperatures, with some batteries potentially overheating while others remain cool. This leads to a decline in overall battery pack performance, especially under high power or fast charging conditions, where overheated batteries may experience capacity decay or damage. Single-sided heat dissipation is insufficient for effective temperature management, necessitating additional active cooling measures (such as air cooling or an additional liquid cooling system) to assist in heat dissipation. This increases system complexity, cost, and weight. This device achieves convenient double-sided heat dissipation and fixation of the battery pack, significantly reducing the possibility of heat accumulation and improving battery pack lifespan.

[0023] By setting up a heat dissipation structure, the heat dissipation efficiency of the battery pack can be easily increased, and the battery pack can be cooled from multiple directions. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 5 The present invention provides a liquid cooling plate with a double-sided heat dissipation structure, comprising: a liquid cooling plate body 1, a liquid cooling pipe 2 installed inside the liquid cooling plate body 1, auxiliary structures 3 on both sides of the liquid cooling plate body 1, and a heat dissipation structure 4 on the arc surface of the liquid cooling pipe 2.

[0033] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The auxiliary structure 3 includes two sliding grooves 31, both of which are formed on the liquid cooling plate body 1. Several sliders 35 are slidably connected to the inner wall of the sliding grooves 31. Fixing plates 34 are fixedly connected to the upper and lower sides of the sliders 35. A limiting plate 32 is fixedly connected to the end of the fixing plate 34 away from the sliders 35. Several heat dissipation strips 33 are fixedly connected to both sides of the limiting plate 32. A screw 37 is threadedly connected to the inner wall of the fixing plate 34. The screw 37 abuts against the liquid cooling plate body 1. When the battery pack needs to be secured, the screw 37 is loosened by rotating it, separating the screw 37 from the liquid cooling plate body 1. Then, the slider 35 is pulled to move, sliding on the inner wall of the groove 31. The slider 35 drives the fixing plate 34 to move, which in turn drives the screw 37 to move. The fixing plate 34 then drives the limiting plate 32 to move, and the limiting plate 32 presses against the battery pack. The heat dissipation strip 33 also increases the friction between the battery pack and the limiting plate 32. Several levers 38 are fixedly connected to the arc surface of the screw 37, and these levers 38 are evenly distributed on the screw 37. When the screw 37 needs to be rotated, the levers 38 can be rotated directly, causing the screw 37 to rotate. The levers 38 make rotating the screw 37 more convenient. A limiting rod 36 is fixedly connected inside the groove 31, and the limiting rod 36 is slidably connected to the slider 35. The limiting rod 36 can limit the slider 35, preventing it from shifting when sliding on the inner wall of the slide rail, thus improving the stability of the slider 35's sliding. The heat dissipation strips 33 are made of aluminum, and several heat dissipation strips 33 are evenly distributed on the limiting plate 32. Aluminum material can increase heat dissipation efficiency, and aluminum material has strong thermal conductivity.

[0034] In the embodiments of this utility model, please refer to Figure 4 and Figure 5The heat dissipation structure 4 includes a fixed pipe 48, which is fixedly connected to the liquid cooling pipe 2. Four connecting rings 44 are fixedly connected to the arc surface of the fixed pipe 48. A connecting pipe 43 is slidably connected to the inner wall of the connecting ring 44. A retaining ring 47 is fixedly connected to the arc surface of the connecting pipe 43. A retaining groove 46 is opened on the inner wall of the connecting ring 44. The retaining groove 46 and the retaining ring 47 are engaged. Heat dissipation pipes 41 are installed inside several limiting plates 32. Two flexible hoses 42 are fixedly connected between two adjacent heat dissipation pipes 41. The flexible hoses 42 are fixedly connected to the connecting pipes 43. When cooling of the battery pack is required, the liquid cooling pipe 2 delivers coolant to the fixed pipe 48, then the fixed pipe 48 delivers coolant to the connecting pipe 43, then the connecting pipe 43 delivers coolant to the hose 42, and then the coolant enters the heat dissipation pipe 41 for circulation. The limiting plate 32 then dissipates heat from the battery pack. After one cycle, the coolant flows back into the connecting pipe 43 and then into the fixed pipe 48. The hose 42 has a circular cross-section and is made of plastic. The plastic material is soft, highly malleable, and inexpensive, reducing the manufacturing cost of the hose 42. A sealing sleeve 45, made of rubber, is fixedly connected inside the connecting ring 44. The sealing sleeve 45 increases the seal between the connecting ring 44 and the connecting pipe 43, preventing leakage when they are connected.

[0035] The working principle of the liquid cooling plate with a double-sided heat dissipation structure provided by this utility model is as follows: When it is necessary to fix the battery pack, the screw 37 is rotated to loosen it and separate the screw 37 from the liquid cooling plate body 1. Then, the slider 35 is pulled to move. The slider 35 slides on the inner wall of the slide groove 31. The slider 35 drives the fixing plate 34 to move. The fixing plate 34 drives the screw 37 to move. The fixing plate 34 drives the limiting plate 32 to move. Then, the limiting plate 32 squeezes the battery plate. The heat dissipation strip 33 can also increase the friction between the battery pack and the limiting plate 32. When it is necessary to rotate the screw 37, the handle 38 can be rotated directly. The handle 38 drives the screw 37 to rotate. The handle 38 makes it easier to rotate the screw 37. The limiting rod 36 can limit the slider 35 to prevent the slider 35 from deviating when sliding on the inner wall of the slide rail, thus improving the stability of the slider 35 sliding. The aluminum material can increase the heat dissipation efficiency, and the aluminum material has strong thermal conductivity.

[0036] When the battery pack needs to be cooled, the liquid cooling pipe 2 delivers coolant to the fixed pipe 48, then the fixed pipe 48 delivers coolant to the connecting pipe 43, then the connecting pipe 43 delivers coolant to the hose 42, and then the coolant enters the heat dissipation pipe 41 for circulation. The limiting plate 32 can then cool the battery pack. After the cooling pipe has flowed once, it enters the connecting pipe 43 and then enters the fixed pipe 48 for return. The plastic pipe material is soft, has strong plasticity, and is inexpensive, which can reduce the manufacturing cost of the hose 42. The sealing sleeve 45 can increase the sealing between the connecting ring 44 and the connecting pipe 43 and prevent leakage when the connecting ring 44 and the connecting pipe 43 are connected.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
