Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1-3, the embodiment provides a high-efficiency aluminum alloy heat sink for a fire-fighting power supply, which includes a box body 1, a circuit board 2, an electronic component 3 and a heat sink 4, wherein a heat dissipation cavity 101 is formed in the box body 1, the circuit board 2 is fixedly arranged on the bottom wall of the heat dissipation cavity 101 through a first fastening screw 5, more than two electronic components 3 are welded on the top of the circuit board 2, the heat sink 4 is arranged on one side of the circuit board 2, two ends of the heat sink 4 are abutted to the top wall and the bottom wall of the heat dissipation cavity 101, and the heat sink 4 is fixedly connected with the electronic component 3 through a second fastening screw 6. Through fixing fin 4 in the outside of circuit board 2, do not occupy the extra space of circuit board 2, reduced the manufacturing cost of circuit board 4, the during operation, the heat that electronic component 3 produced is absorbed by fin 4, then fin 4 conducts the heat that absorbs to box 1 surface to increase heat radiating area improves the radiating effect.

Specifically, the bottom of the heat sink 4 is fixedly provided with more than two pins 11, and the circuit board 2 is provided with a plugging groove 12 matched with the pins 11. When the heat sink 4 is installed, the pins 11 are aligned with the insertion grooves 12, and then the pins 11 are inserted into the insertion grooves 12, so that the heat sink 4 is prevented from sliding left and right in the heat dissipation cavity 101, and the electronic component 3 and the heat sink 4 are conveniently and fixedly connected.

Specifically, the box body 1 includes a box body 102, an end cover 103 and a front panel 104, wherein the end cover 103 is fixedly arranged on the top of the box body 102 through a fourth fastening screw 8, and the front panel 104 is fixedly arranged on one side of the box body 102 through a fifth fastening screw 9.
