In this embodiment, the heat sink includes a heat dissipation plate 400 and a sealing member. The heat sink 400 is provided with an inlet 401, an outlet 402, and a heat sink channel group formed on a side surface of the heat sink 400. The heat dissipation channel set comprises an inlet total flow straight channel 304, an outlet total flow straight channel 301 and a plurality of independent branch flow straight channels. The inlet total flow straight channel 304 is communicated with the inlet 401, the outlet total flow straight channel 301 is communicated with the outlet 402, and the flow dividing straight channel is communicated with the inlet total flow straight channel 304 and the outlet total flow straight channel 301. Since the holes are formed in the side surface of the heat dissipating plate 400 when the straight passages (the inlet total flow straight passage 304, the outlet total flow straight passage 301, and the flow dividing straight passage) are processed, the processing device is inserted into the heat dissipating plate 400 through the holes to form the straight passages, and the holes that do not have the function of use and are generated only when the straight passages are processed are processing holes. In order to avoid the fluid leakage in the heat dissipation channel group, the sealing piece is arranged at the processing opening in a sealing mode.

Preferably, in order to ensure the heat dissipation effect, the heat dissipation plate 400 has a plate structure, and the area of the heat dissipation surface is larger, so that the total length of the heat dissipation channel group processed from the side surface is larger, and the heat dissipation effect is further ensured.
To facilitate heat sink mounting, the inlet 401 and outlet 402 may not employ machined ports. In this embodiment, the inlet 401 is located on the heat radiation surface of the heat radiation plate 400, i.e., an opening is formed from the heat radiation surface of the heat radiation plate 400 so as to communicate with the inlet total flow through passage 304 as the inlet 401. And the outlet 402 is located on the side of the heat dissipation plate 400, that is, during the processing of the outlet total flow path 301, a processing port thereof on the side of the heat dissipation plate 400 is not sealed by a sealing member, but is used as the outlet 402. Of course, the inlet 401 may be located on the side surface of the heat dissipation plate 400, and the outlet 402 may be located on the heat dissipation surface of the heat dissipation plate 400; it is also possible to have the inlet 401 on the side of the heat dissipation plate 400 and the outlet 402 on the side of the heat dissipation plate 400; alternatively, the inlet 401 is located on the heat radiation surface of the heat radiation plate 400 and the outlet 402 is located on the heat radiation surface of the heat radiation plate 400.

Since the channels processed into the heat dissipation plate 400 are all straight channels, the heat dissipation channel group further includes an intermediate total flow straight channel. A portion of the plurality of straight flow-dividing channels communicates with the inlet straight flow-dividing channel 304 and the intermediate straight flow-dividing channel, and another portion thereof communicates with the intermediate straight flow-dividing channel and the outlet straight flow-dividing channel 301. The fluid entering the inlet total straight flow channel 304 from the inlet 401 enters the intermediate total straight flow channel through a part of the branched straight flow channels (the number is at least 1), then flows into another part of the branched straight flow channels (the number is at least 1) from the intermediate total straight flow channel, is gathered into the outlet total straight flow channel 301, and flows out from the outlet 402.
For the convenience of arrangement, the fluid channel formed by the heat dissipation channel group in the embodiment is an "S" shaped channel.

The three groups of the flow dividing straight channels are uniformly divided into three groups, so that the unit volumes of the fluid flowing in the three groups of the flow dividing straight channels are the same, the fluid is prevented from being detained in the flow dividing straight channels due to overlarge flow, the fluid is prevented from being left in the flow dividing straight channels due to undersize flow, and the flow stability is improved. Of course, the number of the branched straight channels and the intermediate total straight channels may be set to other numbers, which will not be described in detail herein.
Further, the diameter of the intermediate total flow straight channel is the same as the diameter of the inlet total flow straight channel 304 and the outlet total flow straight channel 301. Through the arrangement, the unit volumes of the fluid flowing in the intermediate total flow straight channel, the inlet total flow straight channel 304 and the outlet total flow straight channel 301 are the same, and the stability of fluid flowing is further improved.
Further, the diameter of the branched straight channels is smaller than the diameter of the inlet total straight channel 304 and the outlet total straight channel 301. By the above arrangement, the stability of the fluid flow is further ensured.
Preferably, the unit volume of the total fluid of the plurality of straight flow-dividing channels communicating with the total straight flow channel is the same as the unit volume of the fluid of the total straight flow channel. Taking this embodiment as an example, the unit volume of the total fluid in the first straight flow-dividing channel 107, the second straight flow-dividing channel 108 and the third straight flow-dividing channel 109 and the inlet total flow-dividing channel 304. Since the diameters of the intermediate total straight flow channel, the inlet total straight flow channel 304, and the outlet total straight flow channel 301 are the same, that is, in the present embodiment, the unit volume of the total fluid in the three divided straight flow channels is the same as the unit volume of the fluid in one total straight flow channel.
