Background

The heat sink can rapidly dissipate the waste heat generated by the electronic component, and increase the stability and life of the electronic component, and is widely used, and an air cooling system such as a fan or a water cooling system using a fluid for heat exchange may be additionally installed to increase the heat dissipation efficiency of the heat sink.

The core of the water cooling system using fluid for heat exchange is a water cooling radiator, which has a better heat dissipation effect and is the best solution for the application requirement of high load, and the traditional water cooling radiator, such as taiwan publication No. M464724, discloses a water cooling radiator, which allows an upper heat exchange fin set and a lower heat exchange fin set to be alternately arranged in an opposite insertion manner to form a water flow channel, so that the cooling fluid flowing through the water flow channel can contact the upper heat exchange fin set and the lower heat exchange fin set in a large area, thereby increasing the heat exchange efficiency and meeting the requirement of rapid heat dissipation.

However, the water flow channel of the conventional heat sink has no flow guiding design or design that is not suitable for heat flow phenomenon, which results in poor flow or even stagnation area in partial area of the water flow channel. For example, the area far away from the inlet and outlet, such as the side edge area, has a low flow velocity due to the small water pressure, and even forms a stagnant area, which causes the accumulation of heat source and reduces the heat dissipation effect.

Referring to fig. 2, the chamber 11 has an opening 115, and a partition plate 14 and a partition wall 15 are disposed in the chamber 11, wherein the partition plate 14 divides the chamber 11 into an upper region 111 and a lower region 112. As shown in fig. 1B, the partition plate 14 has a central through hole 141 and a peripheral gap 142, the central through hole 141 connects the upper region 111 and the lower region 112, and the peripheral gap 142 also connects the upper region 111 and the lower region 112. In one embodiment, as shown in fig. 1C, the peripheral notches 142 are disposed along four edges 143 of the partition 14, and four corners 144 of the partition 14 abut against the cavity 10, so as to increase the structural stability of the partition 14.

Referring to fig. 1B and 1C, the upper region 111 is divided by the partition wall 15 to have a water inlet channel 113 and a water outlet channel 114, the water inlet channel 113 is connected to the inlet pipe 12 and the central through hole 141, and the water outlet channel 114 is connected to the outlet pipe 13 and the peripheral gap 142. In one embodiment, the chamber 10 has an inlet hole 16, the inlet hole 16 communicates with the inlet channel 113, and the inlet pipe 12 joins the inlet hole 16. Similarly, the chamber 10 has an outlet hole 17, the outlet hole 17 is connected to the outlet flow passage 114, and the outlet pipe 13 is connected to the outlet hole 17.

The heat sink fins 20 are disposed on the temperature-uniforming plate 30, and the temperature-uniforming plate 30 is inserted into the cavity 11 and is sealed and fixed in the opening 115 to allow the heat sink fins 20 to be located in the lower region 112. The radiator fins 20 may have various shapes in practical implementation, for example, the radiator fins 20 may be cylindrical or square as drawn in fig. 3, and so on.
