[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.
[0027] like Figures 1 to 6 As shown, the utility model provides a specific embodiment of a liquid cooling heat dissipation device.
[0028] A liquid cooling device, reference Figure 1 The liquid cooling device includes a cooling and cooling unit 1, a liquid return pipe 2 and at least two liquid inlet pipes, one end of the liquid return pipe 2 is connected to the cooling and cooling unit 1, and the other end of the liquid return pipe 2 is used to connect to the external cushion body, one end of the at least two liquid inlet pipes are connected to the cooling and cooling unit 1, and the other end of the at least two liquid inlet pipes are used to connect to the external cushion body.
[0029] Specifically, refer to Figure 1 The liquid cooling device is connected to the external cushion body through a liquid inlet pipe and a liquid return pipe 2 to form a circulating liquid flow loop, thereby dissipating the heat of the external components to be cooled, wherein the liquid is cooled by the cooling and heat dissipation unit 1, and the cooled liquid is output to the external cushion body through the liquid inlet pipe. After the cooled liquid enters the external cushion body, it can absorb the heat on the external components that need to be cooled. The hot liquid after absorbing the heat will flow back to the cooling and heat dissipation unit 1 through the return pipe. After being cooled by the cooling and heat dissipation unit 1, the hot liquid is output to the external cushion body through the liquid inlet pipe again, and the heat on the external components that need to be cooled is absorbed again. This is repeated to achieve the effect of dissipating the heat of the external components that need to be cooled.
[0030] In this embodiment, reference Figure 1The liquid cooling device includes a first liquid inlet pipe 31 and a second liquid inlet pipe 32, one end of the first liquid inlet pipe 31 and one end of the second liquid inlet pipe 32 are both connected to the refrigeration and heat dissipation unit 1, and the other end of the first liquid inlet pipe 31 and the other end of the second liquid inlet pipe 32 are both used to connect to an external cushion body; when the external component that needs to be cooled is a cushion body with a large surface area such as a car seat cushion, the liquid cooling device can transport cold liquid to the cushion body from multiple directions and multiple positions through the first liquid inlet pipe 31 and the second liquid inlet pipe 32, thereby achieving rapid cooling of large-area components.
[0031] In one embodiment, reference Figure 2 The refrigeration and heat dissipation unit 1 includes a shell 11, a refrigeration module 12 and a heat dissipation module 13. The refrigeration module 12 and the heat dissipation module 13 are arranged in the shell 11. The refrigeration module 12 and the heat dissipation module 13 can be arranged side by side in the shell 11, or can be stacked in the shell 11, which is not limited in the embodiment.
[0032] Specifically, refer to Figure 2 The shell 11 includes a bottom plate 111 and a cover plate 112. The refrigeration module 12 and the heat dissipation module 13 are both fixedly arranged on the bottom plate 111, and the heat dissipation module 13 is arranged on one side of the refrigeration module 12. The cover plate 112 covers the refrigeration module 12 and the heat dissipation module 13 and is fixed to the bottom plate 111; wherein the heat dissipation module 13 and the refrigeration module 12 are arranged side by side, which can effectively reduce the occupied space of the refrigeration and heat dissipation unit 1, thereby reducing the overall volume of the liquid-cooled heat dissipation device, making the product more miniaturized and easier to carry.
[0033] In one embodiment, reference Figure 2 and Figure 3 The heat dissipation module 13 includes a fan 131 and heat dissipation fins 132 . The fan 131 and the refrigeration module 12 are arranged side by side, and the heat dissipation fins 132 cover the fan 131 and the refrigeration module 12 .
[0034] Specifically, refer to Figures 1 to 3 The heat dissipation fins 132 are used to increase the heat dissipation surface area. The heat dissipation fins 132 are usually composed of a plurality of thin and flat sheet structures, which can effectively increase the contact area with the surrounding air and promote the conduction and dissipation of heat. When the refrigerated liquid enters the external pad through the liquid inlet pipe and absorbs the heat on the component to be cooled, the liquid with heat is input back to the refrigeration and heat dissipation unit 1 through the return liquid pipe 2. The heat dissipation fins 132 can absorb the heat in the liquid input back to the refrigeration and heat dissipation unit 1; the fan 131 can generate airflow, so that the external air continuously blows through the heat dissipation fins 132 and takes away the problems on the surface of the heat dissipation fins 132, thereby achieving the heat dissipation effect.
[0035] Among them, reference Figures 1 to 3By arranging the fan 131 and the cooling module 12 side by side, stacking of multiple devices can be avoided, so as to effectively reduce the overall thickness of the cooling and heat dissipation unit 1. By covering the cooling fins 132 on the fan 131 and the cooling module 12, the heat of the hot liquid in the cooling module 12 can be absorbed, and ventilation with the outside can be performed through the fan 131 to dissipate the absorbed heat into the external air.
[0036] In one embodiment, reference Figure 2 and Figure 3 The cooling module 12 includes a liquid tank 121 , a cooling cover plate 122 and cooling fins 123 . The cover plate 112 is disposed on the liquid tank 121 , and the cooling fins 123 are disposed on the cooling cover plate 122 .
[0037] Specifically, refer to Figures 2 to 4 The liquid tank 121 includes a liquid inlet chamber 1211 and a liquid return chamber 1212. The liquid inlet chamber 1211 is used to store cold liquid after refrigeration. The liquid inlet chamber 1211 is connected to the external pad body through the first liquid inlet pipe 31 and the second liquid inlet pipe 32 to provide cold liquid for cooling. The liquid return chamber 1212 is used to store hot liquid that flows back to the refrigeration module 12 through the external pad body. The liquid return chamber 1212 is connected to the external pad body through the liquid return pipe 2; by storing cold liquid and hot liquid respectively through the liquid inlet chamber 1211 and the liquid return chamber 1212, the heat of the hot liquid can be effectively prevented from entering the cold liquid, so as to avoid the hot liquid being output to the external pad body through the liquid inlet pipe again, thereby ensuring the cooling effect.
[0038] Further, refer to Figure 3 The cold-conducting cover plate 122 is arranged on the liquid tank 121. On the one hand, the cold-conducting cover plate 122 can seal the liquid tank 121 to prevent the liquid in the liquid tank 121 from flowing out and damaging other devices. On the other hand, the cold-conducting cover plate 122 is made of a material with good thermal conductivity, which can conduct heat from the hot liquid more quickly, thereby accelerating the cooling of the liquid.
[0039] In one embodiment, reference Figure 3 and Figure 4 A sealing rubber ring 1213 is provided on the liquid box 121 .
[0040] Specifically, refer to Figure 3 and Figure 4A sealing rubber ring 1213 is arranged at the edge of the box opening of the liquid tank 121. Since it is difficult to completely seal the cold-conducting cover plate 122 and the edge of the box opening of the liquid tank 121, a gap is likely to exist. During use, the liquid in the liquid tank 121 is likely to flow out through the gap. In order to improve the working stability of the liquid-cooling heat dissipation device, a liquid-proof rubber ring is arranged at the edge of the box opening of the liquid tank 121 in this embodiment. When the cold-conducting cover plate 122 covers the liquid tank 121, the gap between the contact positions of the two will be blocked by the liquid-proof rubber ring, which can effectively improve the sealing of the liquid tank 121.
[0041] In one embodiment, reference Figures 1 to 3 The shell 11 is provided with an air outlet 113 , and the air outlet 113 is connected to the fan 131 .
[0042] Specifically, refer to Figure 2 and Figure 3 The rotation of the fan 131 can generate airflow, so that the air around the liquid cooling device continuously enters and exits the housing 11 through the air outlet 113, so as to continuously take away the heat on the cooling fins 132, thereby achieving a heat dissipation effect.
[0043] like Figure 5 As shown, the utility model provides a specific embodiment of a liquid cooling and heat dissipation system.
[0044] refer to Figure 5 The liquid cooling system includes a cooling pad 4 and the above-mentioned liquid cooling device. The cooling pad 4 is provided with a liquid return port 43 and at least two mutually connected cooling zones. Each cooling zone is provided with a corresponding liquid inlet. The liquid return port 43 is connected to the liquid return pipe 2, and each liquid inlet is connected to a liquid inlet pipe.
[0045] In this embodiment, reference Figure 5 The heat dissipation pad 4 includes two interconnected first heat dissipation areas 41 and second heat dissipation areas 42. The first heat dissipation area 41 is provided with a first liquid inlet 44, which is connected to the refrigeration and heat dissipation unit 1 through a first liquid inlet pipe 31. The second heat dissipation area 42 is provided with a second liquid inlet 45, which is connected to the refrigeration and heat dissipation unit 1 through a second liquid inlet pipe 32. A return liquid port 43 is provided on the first heat dissipation area 41 or the second heat dissipation area 42, and the return liquid port 43 is connected to the refrigeration and heat dissipation unit 1 through a return liquid pipe 2. The cold liquid in the refrigeration and heat dissipation unit 1 can enter the first heat dissipation area 41 through the first liquid inlet pipe 31, and can enter the second heat dissipation area 42 through the second liquid inlet pipe 32. The cold liquid is transported to different heat dissipation areas in the heat dissipation pad 4 from multiple directions through the first liquid inlet pipe 31 and the second liquid inlet pipe 32, which can accelerate the cooling speed of large-area components.
[0046] In one embodiment, reference Figure 6The liquid cooling and heat dissipation system also includes a shell 5 , the liquid cooling and heat dissipation device is arranged in the shell 5 , and the heat dissipation pad 4 is partially arranged in the shell 5 .
[0047] Specifically, refer to Figure 6 A through hole 51 is provided at the position of the shell 5 corresponding to the air outlet 113, the liquid cooling heat dissipation device is arranged in the shell 5, and the air outlet 113 passes through the through hole 51 and is exposed on the surface of the shell 5, and one side of the heat dissipation pad 4 provided with the liquid inlet and the liquid return port 43 is wrapped in the shell 5, and the other side of the heat dissipation pad 4 is exposed outside the shell 5, so as to improve the structural stability of the liquid cooling heat dissipation device while maintaining the heat dissipation effect.
