When in use, the heat exchange medium in the circulation channel is used to take away the heat to achieve the heat dissipation of the heating element. Since the water source inlet is located on one side of the heat dissipation cold plate, in order to achieve a faster heat dissipation effect and ensure uniform heat dissipation at various positions of the heating element, a branch channel structure is adopted in the prior art, including a direct flow channel and multiple water outlets arranged along the extension direction of the direct flow channel, and all the water outlets are connected to the circulation channel.

[0003] The applicant has found that the prior art has at least the following technical problems:

[0004] One end of the direct flow channel in the existing branch channel structure is connected to the water source. After the heat exchange medium enters through one end of the direct flow channel, it flows out through the water outlet in sequence and enters the circulating flow channel. This structure makes the process of the heat exchange medium entering the circulating flow channel longer and the flow rate is slow. Moreover, it cannot be quickly transported to different positions of the heating element, and can only slowly exchange heat from one side of the heating element to the other side, resulting in uneven heat exchange and affecting the heat dissipation effect.
