Built-in self-cooling distribution box for outdoor high temperature in summer

Abstract

The invention provides a built-in self-cooling distribution box for outdoor high temperature in summer. The distribution box comprises a supporting mechanism, a liquid cooling mechanism, an air cooling mechanism and a starting mechanism, and is characterized in that the liquid cooling mechanism, the air cooling mechanism and the starting mechanism are arranged in an inner cavity of the supporting mechanism, and the starting mechanism is fixedly connected to the middle part of the inner wall of the inner side of the supporting mechanism; the air cooling mechanism is fixedly connected to the outer side of the starting mechanism, the liquid cooling mechanism is fixedly connected to the outer side of the air cooling mechanism, the supporting mechanism comprises a box body, a ventilation pipe is inserted in the middle of the upper surface of the box body through a hole groove, and a fixing plate is fixedly connected to the inner side of the inner wall of the box body. According to the built-in self-cooling distribution box for the outdoor high temperature in summer, a special structure which combines liquid cooling and air cooling and automatically reacts to the high temperature is designed according to the situation that an existing distribution box cannot continuously work in a high-temperature environment; therefore, the problem that a common distribution box cannot be cooled and cannot respond to high temperature in an extremely high-temperature working environment in summer is effectively solved.

Description

Technical field[0001]The present invention relates to the technical field of distribution tabs, in particular a built-in self-cooling electric cartridge with an outdoor high temperature in summer.Background technique[0002]The low-voltage electrical appliance in the distribution box is composed of a fuse, an alternating contactor, a residual current motion protector, a capacitor, and a metering table. The upper limit of the surrounding air temperature does not exceed 40 ° C; the average value of the surrounding air temperature is not more than 35 ° C; the lower limit of the surrounding air temperature is not less than -5 ° C or -25 ° C, when the distribution box is run outdoors, it is not only sunny Direct illumination produces a high temperature, and it will generate heat in operation, so in the high temperature season in the summer, the temperature in the box will reach 60 ° C, and the temperature is much higher than the ambient temperature specified in these appliances.[0003]Nowad...
