[0040] A plurality of heat dissipation fins 40 are connected between adjacent two water passages 30, and / or the heat dissipation fins 40 are connected to the shell 10.

[0041] The technical scheme of the utility model discloses a liquid cooling structure including a shell 10, a water collecting cavity 21, a water distribution cavity 22, a plurality of water passages 30 and heat dissipation fins 40, the water collecting cavity 21 is installed on the shell 10, and a water collecting cavity is formed in the water collecting cavity 21. The water distribution cavity 22 is installed on the shell 10, and a partition plate is arranged in the water distribution cavity 22 to form a water inlet cavity and a water outlet cavity. The cavity wall of the water inlet cavity and the cavity wall of the water outlet cavity are respectively provided with a water inlet and a water outlet. Both ends of the plurality of water passages 30 are respectively connected to the water distribution cavity 22 and the water collecting cavity 21. Part of the plurality of water passages 30 are respectively connected to the water inlet cavity and the water collecting cavity 21. The other part of the plurality of water passages 30 are respectively connected to the water outlet cavity and the water collecting cavity 21. A plurality of heat dissipation fins 31 are arranged in the water passage 30. The heat dissipation fins 31 extend along the length direction of the water passage 30. The heat dissipation fins 40 are connected between adjacent two water passages 30, and / or the heat dissipation fins 40 are connected to the shell 10. In the technical scheme of the application, the heat dissipation fins 31 are arranged in the water passage 30 to destroy the thermal boundary layer and the flow boundary layer, increase the turbulent flow, increase the convective heat transfer, and improve the heat exchange and heat dissipation effect of the water passage 30. At the same time, the contact area between the cooling liquid and the pipe wall in the water passage 30 is increased, thereby further improving the heat dissipation effect of the water passage 30. Finally, the heat is transferred to the surrounding air and the heat dissipation fins 40 through the pipe wall of the water passage 30, and finally the heat is dissipated through the fan. At the same time, the heat dissipation fins 31 can also increase the structural strength of the water passage 30, thereby improving the stability, reliability and service life of the water passage 30.

[0042] In the technical scheme of the utility model, the flow sequence of the cooling liquid is: the cooling liquid first flows into the water inlet cavity from the water inlet, then flows into the plurality of water passages 30 connected to the water inlet cavity through the water inlet cavity, then the cooling liquid flows into the water collecting cavity 21, then flows into the plurality of water passages 30 connected to the water outlet cavity through the water collecting cavity 21, and finally flows into the water outlet cavity through the corresponding water passage 30, thereby completing the whole water cooling and heat dissipation process.

[0043] Referring to Figures 3 to 5 In the first embodiment, the heat dissipation fins 31 are arranged perpendicularly to the pipe wall of the water passage 30. Thus, the production and processing of the heat dissipation fins 31 are facilitated, and the material required for the heat dissipation fins 31 is reduced, thereby reducing the production and processing difficulty and the production cost of the water passage 30.

[0044] In the second embodiment, the heat dissipation fins 31 are arranged obliquely to the pipe wall of the water passage 30. By arranging the heat dissipation fins 31 obliquely, the area of the heat dissipation fins 31 is increased, thereby increasing the contact area between the cooling liquid and the heat dissipation fins 31 in the water passage 30, and further increasing the heat exchange and heat dissipation effect of the water passage 30.

[0045] Of course, in other embodiments, the heat dissipation fins 31 can also be arranged in a wave shape, an arc shape, etc., to increase the contact area between the cooling liquid and the heat dissipation fins 31.

[0046] Specifically, the heat dissipation fins 31 are integrally formed with the water passage 30. Thus, the connection strength between the heat dissipation fins 31 and the water passage 30 is increased, thereby improving the service life of the water passage 30. Of course, in other embodiments, the heat dissipation fins 31 and the water passage 30 can be integrally formed by welding, integrally formed by injection molding, integrally formed by casting, etc.

The two ends of the water passage 30 are respectively welded on the water distribution cavity 22 and the water collection cavity 21, so that the two ends of the water passage 30 are first limited by the limit through holes 23, and then the water passage 30 is welded after the limiting is completed, thereby avoiding the possibility of deviation and shaking of the water passage 30 during welding, and further reducing the processing difficulty of the water passage 30.

[0048] Further, the hole wall of the limit through hole 23 protrudes from the cavity wall of the corresponding water distribution cavity 22 and water collection cavity 21. Thus, the contact area between the limit through hole 23 and the water passage 30 is increased, thereby further increasing the stability and reliability of the water passage 30, and also increasing the welding area between the water passage 30 and the corresponding water distribution cavity 22 and water collection cavity 21, thereby further improving the stability and reliability of the water passage 30.

[0049] Referring to Figure 2In an embodiment, the shell 10 comprises a mounting plate 11, the heat dissipation fins 40 on both sides are connected to the mounting plate 11, and both ends of the mounting plate 11 are provided with a clamping plate 111, and the two clamping plates 111 are buckled at the openings of the water distribution cavity 22 and the water collecting cavity 21 respectively.

Meanwhile, the mounting mode of the clamping plate 111 is simple and reliable, thereby facilitating the installation of the mounting plate 11. The clamping plate 111 is used to preliminarily position the mounting plate 11 and the heat dissipation fins 40, and then the clamping plate 111 is welded and fixed with the water distribution cavity 22 and the water collecting cavity 21, thereby avoiding the possibility of deviation of the mounting plate 11 in the welding process, and further improving the stability and reliability of the liquid cooling row structure.

[0050] With reference to Figure 1 , Figure 2 , Figure 7 and Figure 8 , specifically, the shell 10 comprises a cover plate 12, both ends of the cover plate 12 are provided with a plugging protrusion 121, both ends of the cover plate 12 are covered at the openings of the water distribution cavity 22 and the water collecting cavity 21, and the plugging protrusion 121 is plugged into the water distribution cavity 22 and the water collecting cavity 21. After the welding of the water channel 30 with the water distribution cavity 22 and the water collecting cavity 21 is completed, the openings at both ends of the water distribution cavity 22 and the water collecting cavity 21 are plugged by the plugging protrusion 121 on the cover plate 12, thereby improving the sealing effect of the water distribution cavity 22 and the water collecting cavity 21, further improving the air tightness of the water distribution cavity 22 and the water collecting cavity 21, and further improving the service life of the liquid cooling row structure.

[0051] Specifically, the cover plate 12 is provided with a plurality of mounting holes 122. The mounting holes 122 are used to facilitate the mounting and fixing of the cover plate 12 with external equipment, thereby improving the installation efficiency of the liquid cooling row structure.
