A heat dissipation mechanism of a helicopter power supply box

Abstract

A heat dissipation mechanism for a helicopter power box disclosed, the mechanism includes two splints, slots are arranged in the inner walls of the opposite sides of the bottoms of the two splints, pull rods are inserted into the inner walls of the slots, the same connecting plate is slidably connected with outer walls of opposite sides of the two pull rods, that the outer wall of the top of the connecting plate is provided with a groove, the inner walls of both sides of the groove are fixedly provided with the same spring hinge through screws, two fixing blocks are welded on both sides of theouter walls of the bottom of the splint, and screw holes are formed on the outer walls of the fixing blocks, and the inner walls of the screw holes are connected with locking screws through screws. The splints cooperate with the upper pull rods and the spring hinge, the heat dissipation device can be clamped on the outer wall of different power supply boxes, the application range is relatively wide, and the dust-proof screen plate can be used for dust-proof treatment, the heat storage cabinet and the exhaust fan can quickly suck out the heat, and the temperature sensor can be matched for heatdissipation when the temperature is too high, and the heat dissipation grille and the semiconductor heat dissipation plate can convert the heat discharged from the power supply box into warm air to be blown out, and recycles the heat.

Description

technical field [0001] The invention relates to the technical field of helicopter power box machines, in particular to a heat dissipation mechanism for a helicopter power box. Background technique [0002] The power box is mainly to provide operating power for vacuum circuit breakers and other high-voltage switches. The power box adopts an input voltage of 220V or 380V through silicon controlled rectification and rectification, and outputs DC. It has the characteristics of output DC voltage with multiple levels of adjustable current or AC Voltage, the function of single-point and single-close operation, they all have their own radiators, but because the radiator is installed inside the shell, the heat dissipation effect is not ideal, especially for thin and light power boxes, when used in summer, the heat on the bottom plate is particularly high High, needs to be improved urgently. The main heating equipment of the power box is the battery. The heat dissipation device for th...

[0002] The power box is mainly to provide operating power for vacuum circuit breakers and other high-voltage switches. The power box adopts an input voltage of 220V or 380V through silicon controlled rectification and rectification, and outputs DC. It has the characteristics of output DC voltage with multiple levels of adjustable current or AC Voltage, the function of single-point and single-close operation, they all have their own radiators, but because the radiator is installed inside the shell, the heat dissipation effect is not ideal, especially for thin and light power boxes, when used in summer, the heat on the bottom plate is particularly high High, needs to be improved urgently. The main heating equipment of the power box is the battery. The heat dissipation device for the power box is assisted by a small table fan in the market. Effect
