[0002] As we all know, heat dissipation from high-heat generating components like CPUs, GPUs, and chips is primarily achieved through conduction. This involves the heat sink, a medium in direct contact with the processor. After absorbing heat, the heat sink dissipates it through convection. During convection cooling, the heat dissipation area is primarily determined by the surface area of the heat sink fins. The larger the surface area, the better the heat dissipation effect; the smaller the surface area, the worse the heat dissipation effect. To improve heat dissipation, the industry uses water cooling, which uses a heat transfer medium to flow through the fins to remove heat, thereby achieving rapid cooling.
[0003] The existing water-cooled heat dissipation cold plate includes a shell, fins and a cover; a water inlet and a water outlet are set on the cover, and fins are set inside the shell. The heat exchange medium enters through the water inlet, then flows through the fins and finally flows out through the water outlet, thereby realizing heat exchange and heat dissipation in a cycle.
[0004] The applicant has discovered that the prior art has at least the following technical problems: the flow channel structure provided in the existing heat dissipation cold plate is unreasonable, resulting in not only a slow flow rate but also insufficient pressure bearing capacity of the heat dissipation cold plate.

[0008] As a further improvement of the present invention, the two flow channels include a first flow channel and a second flow channel; wherein the first flow channel and the second flow channel are arranged in a cross shape with the two supports.

[0023] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0024] like Figures 1-6 As shown, the present invention provides a two-channel 4 heat dissipation housing for a water-cooled cold plate, comprising a base housing 1 with a receiving cavity and a cover 2 covering the open portion of the base housing 1. Heat dissipating fins 3 are positioned in the center of the receiving cavity, spaced apart from the four edges of the cavity. Solid supports 7 are provided on opposite sides of the spaced-apart housing, forming two flow channels 4 between the opposing edges of the heat dissipating fins 3 and the inner wall of the cavity. It should be noted that the opposing edges of the heat dissipating fins 3 referred to herein are the edges without the supports 7.
[0025] The support frame 7 is provided to improve the pressure bearing capacity of the heat dissipation housing, and can also improve the pressure bearing capacity of the heat dissipation fins.
[0026] As a further improvement of the present invention, the two flow channels 4 include a first flow channel and a second flow channel, wherein the first flow channel and the second flow channel are arranged opposite to each other, and the first flow channel and the second flow channel are arranged in a cross shape with the two supports 7. The heat exchange medium in the first flow channel enters the heat dissipation fins 3, and then finally flows into the second flow channel and flows out from the water outlet 6.
[0027] The cover 2 is provided with a water inlet 5 and a water outlet 6; the water outlet 6 corresponds to the second flow channel, and the water inlet 5 corresponds to the first flow channel. Of course, the number of water inlets and outlets can also be set to multiple, but the water inlet must correspond to the first flow channel, and the water outlet must correspond to the second flow channel.
[0028] As a further improvement of the present invention, in this embodiment, the water outlet 6 is located in the middle of the second flow channel, the water inlet 5 is located in the middle of the first flow channel, and the centers of the water outlet 6 and the water inlet 5 are on the same straight line. This structural arrangement shortens the heat exchange medium flow path, improves heat exchange effect, and increases flow rate.
[0029] As a further improvement of the present invention, the top of the support frame is connected to the cover 2 via a fixing pin 8 .

[0031] It should be noted here that in order to save costs and reduce weight, the support frame 7 may not be made into a solid structure, but its four sides or the surfaces opposite to the first flow channel and the second flow channel should be closed surfaces, so that the gap in which it is located can be blocked and no heat exchange medium can flow in.
[0032] As a further improvement of the present invention, the length of the fixing pin 8 is equal to the thickness of the cover 2 ; or, the length of the fixing pin 8 is greater than the thickness of the cover 2 .
[0033] The utility model provides a water-cooled heat dissipation cold plate with two flow channels 4 heat dissipation shell, by arranging the heat dissipation fins 3 in the middle position of the heat dissipation shell, and forming flow channels 4 at the three sides of the heat dissipation fins 3 and the heat dissipation shell, so that the heat exchange medium will flow into the flow channels 4 on both sides after passing through the heat dissipation fins 3, and the flow channels 4 on both sides are connected with the flow channel on the third side, so that the heat exchange medium can quickly reflux, with high speed and good heat exchange effect; by arranging the support frame 7, the pressure bearing capacity of the heat dissipation shell is improved.
