[0025] 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.
[0026] like Figures 1 to 4 As shown, the utility model provides a specific embodiment of a liquid cooling heat dissipation device.
[0027] A liquid cooling device, reference Figure 1 and Figure 2 The liquid cooling device includes a cooling and cooling unit 1 and a liquid pipe 2. The cooling and cooling unit 1 is connected to an external pad through the liquid pipe 2. The cooling and cooling unit 1 includes a shell 11, a fan 12, a liquid tank 13, a cooling sheet 14, a first cooling fin 15 and a second cooling fin 16. The fan 12 and the liquid tank 13 are arranged side by side in the shell 11, the cooling sheet 14 is arranged on the liquid tank 13, the first cooling fin 15 is arranged on the fan 12, and the second cooling fin 16 is arranged on the cooling sheet 14.
[0028] Specifically, refer to Figure 1 and Figure 2 The refrigeration and heat dissipation unit 1 includes a refrigeration fin 14 and a liquid tank 13, which are used for refrigeration. After the liquid in the liquid tank 13 is refrigerated by the refrigeration fin 14, the low-temperature liquid is output through the liquid pipe 2. In this way, when the refrigeration and heat dissipation unit 1 is connected to the external cushion body through the liquid pipe 2, the liquid can be input into the external cushion body through the liquid pipe 2 to absorb the heat on the component to be cooled, thereby reducing the temperature of the component to be cooled; the external cushion body can be a seat cushion, a back cushion, or a cushion body that contacts the back of electronic devices such as mobile phones and tablets.
[0029] Further, refer to Figure 1 and Figure 2The refrigeration and heat dissipation unit 1 also includes a fan 12, a first heat dissipation fin 15 and a second heat dissipation fin 16. The fan 12, the first heat dissipation fin 15 and the second heat dissipation fin 16 are used for heat dissipation. The surface area of the first heat dissipation fin 15 and the second heat dissipation fin 16 is large and porous, so that they have a large contact area with the external air. When the refrigerated liquid enters the external pad through the liquid pipe 2 and absorbs the heat on the component to be cooled, the hot liquid with heat is input back to the liquid tank 13 through the liquid pipe 2. The first heat dissipation fin 15 and the second heat dissipation fin 16 can absorb the heat in the hot liquid input back to the liquid tank 13, and the fan 12 can generate airflow, so that the external air blows through the first heat dissipation fin 15 or the second heat dissipation fin 16, and takes away the heat on the surface of the first heat dissipation fin 15 and the second heat dissipation fin 16, so as to reduce the surface temperature of the first heat dissipation fin 15 and the second heat dissipation fin 16, thereby achieving a heat dissipation effect.
[0030] Among them, reference Figure 1 and Figure 2 By arranging the fan 12 and the liquid tank 13 side by side in the shell 11, and arranging the cooling fin 14 on the liquid tank 13, it is possible to avoid multi-layer stacking of devices, thereby reducing the overall thickness of the liquid-cooled heat dissipation device, making the liquid-cooled heat dissipation device thinner and more portable; by arranging the first heat dissipation fin 15 and the second heat dissipation fin 16, and arranging the first heat dissipation fin 15 and the second heat dissipation fin 16 on the fan 12 and the cooling fin 14 respectively, not only the structural hierarchy can be reduced, but also the heat dissipation area can be increased to accelerate the heat dissipation speed, thereby achieving a better heat dissipation effect.
[0031] In one embodiment, reference Figure 3 A heat pipe 17 is disposed between the first heat dissipation fin 15 and the second heat dissipation fin 16 , and the first heat dissipation fin 15 and the second heat dissipation fin 16 are connected through the heat pipe 17 .
[0032] Specifically, refer to Figure 3 The heat pipe 17 is used to accelerate the heat transfer between the first heat dissipation fin 15 and the second heat dissipation fin 16. When one of the first heat dissipation fin 15 or the second heat dissipation fin 16 absorbs the heat in the hot liquid input back into the liquid tank 13, the heat can be quickly transferred to the other of the first heat dissipation fin 15 or the second heat dissipation fin 16 through the heat pipe 17. Finally, the fan 12 generates airflow so that the external air takes away the heat.
[0033] Among them, reference Figure 3 In order to transfer heat more quickly, multiple heat pipes 17 can be provided to increase the contact area between the first heat sink fins 15 and the second heat sink fins 16; further, the heat pipes 17 can be made of metal with strong thermal conductivity, such as copper pipes, to improve the heat dissipation effect.
[0034] In one embodiment, reference Figure 2 and Figure 3 A cooling cover plate 18 is disposed between the liquid tank 13 and the cooling fins 14 . The cooling cover plate 18 covers the liquid tank 13 , and the cooling fins 14 are disposed on the cooling cover plate 18 .
[0035] Specifically, refer to Figure 2 and Figure 3 The cooling cover plate 18 covers the liquid tank 13 and can seal the liquid tank 13 to prevent the liquid in the liquid tank 13 from overflowing; the cooling cover plate 18 can be made of a material with good thermal conductivity to more quickly conduct the heat in the hot liquid and accelerate the cooling of the liquid.
[0036] In one embodiment, reference Figure 4 A liquid-proof rubber ring 131 is provided at the edge of the box opening of the liquid box 13.
[0037] Specifically, refer to Figure 3 and Figure 4 When the cooling cover 18 covers the liquid tank 13, it is difficult to completely seal the cooling cover 18 with the edge of the box opening of the liquid tank 13, and a gap is likely to exist. During use, the liquid in the liquid tank 13 may overflow from the gap. In order to improve the working stability of the liquid cooling heat dissipation device, this embodiment will set a liquid-proof rubber ring 131 at the edge of the box opening of the liquid tank 13. When the cooling cover 18 covers the liquid tank 13, the gap between the contact positions of the two will be blocked by the liquid-proof rubber ring 131, which can effectively improve the sealing of the liquid tank 13.
[0038] In one embodiment, reference Figure 3 and Figure 4 The liquid box 13 includes a liquid inlet chamber 132 and a liquid return chamber 133, and the liquid inlet chamber 132 and the liquid return chamber 133 are partially isolated by a partition.
[0039] Specifically, refer to Figure 3 and Figure 4 The liquid inlet chamber 132 is used to store cold liquid after refrigeration, and the liquid return chamber 133 is used to store hot liquid returned through the external pad body; by storing the cold liquid and the hot liquid respectively in the liquid inlet chamber 132 and the liquid return chamber 133, it is possible to prevent the hot liquid from completely entering the cold liquid, thereby improving the refrigeration effect; the liquid inlet chamber 132 and the liquid return chamber 133 both use the same liquid tank 13, and by arranging a partition in the middle of the liquid tank 13 to achieve partial isolation, the number of tanks can be effectively reduced, thereby reducing the overall volume of the liquid-cooled heat dissipation device, making the liquid-cooled heat dissipation device thinner and more portable.
[0040] In one embodiment, reference Figure 3 and Figure 4The liquid pipe 2 includes a liquid inlet pipe 21 for connecting the external pad body and the liquid inlet chamber 132, and a liquid return pipe 22 for connecting the external pad body and the liquid return chamber 133.
[0041] Specifically, refer to Figure 3 and Figure 4 The liquid inlet pipe 21 is used to transport the cold liquid in the liquid inlet cavity 132 to the external cushion body, and the liquid return pipe 22 is used to transport the hot liquid that has absorbed heat in the external cushion body back to the liquid return cavity 133.
[0042] In one embodiment, reference Figure 2 An air outlet 111 is provided on the housing 11 at a position corresponding to the fan 12 .
[0043] Specifically, refer to Figure 2 The rotation of the fan 12 can generate airflow, so that the air around the liquid cooling device continuously enters and exits the shell 11 through the air outlet 111, so as to continuously take away the heat on the first cooling fins 15 or the second cooling fins 16, thereby achieving a heat dissipation effect.
[0044] like Figure 5 to Figure 6 As shown, the utility model also provides a specific embodiment of a liquid cooling and heat dissipation system.
[0045] refer to Figure 5 The liquid cooling system includes a heat dissipation pad 3, a refrigeration and heat dissipation unit 1 and a liquid pipe 2. The heat dissipation pad 3 is provided with a plurality of accommodating cavities and connecting channels, and the plurality of accommodating cavities are connected by connecting channels.
[0046] Specifically, refer to Figure 5 , multiple accommodating cavities are evenly distributed in the heat dissipation pad 3, and the multiple accommodating cavities are connected through connecting channels; when the refrigerated cold liquid enters the heat dissipation pad 3 through the liquid inlet pipe 21, it can enter each accommodating cavity through the connecting channel, so that the surface of the heat dissipation pad 3 can evenly absorb heat, thereby improving the heat dissipation effect.
[0047] In one embodiment, reference Figure 5 and Figure 6 The liquid cooling device also includes a shell 4 , the cooling and cooling unit 1 and the liquid pipe 2 are both arranged in the shell 4 , and the heat dissipation pad 3 is partially arranged in the shell 4 .
[0048] Specifically, refer to Figure 5 and Figure 6A through hole 41 is provided at the position of the shell 4 corresponding to the air outlet 111, the refrigeration and heat dissipation unit 1 and the liquid pipe 2 are both arranged in the shell 4, and the air outlet 111 passes through the through hole 41 and is exposed on the surface of the shell 4, and one side of the heat dissipation pad 3 connected to the liquid pipe 2 is wrapped in the shell 4, and the other side of the heat dissipation pad 3 is exposed outside the shell 4, so as to improve the structural stability of the liquid cooling device while maintaining the heat dissipation effect.
