Abstract

The invention provides a high voltage distribution box, which relates to the field of automotive high voltage electrical systems. The high voltage distribution box comprises a box body, a fan bottom bin, a fan, a mounting plate, a heating device, a fan switch, and a temperature detection device, wherein the side surfaces of the box body are provided with air outlets; the fan bottom bin is fixedly connected with the box body; the box body and the fan bottom bin form accommodating space; the fan is arranged in the accommodating space and is fixedly arranged on the fan bottom bin; the mounting plate is arranged above the fan, and the mounting plate is fixedly connected with the box body; the heating device and the fan switch are fixed on the mounting plate; the temperature detection device is arranged in the accommodating space; and the temperature detection device and the fan switch are respectively connected with a battery management system. The temperature in the accommodating space is detected through the temperature detection device, the battery management system judges the temperature, if the temperature is higher than a preset value, the fan works, air enters from air inlets and air is exhausted from the air outlets in the side surfaces of the box body, or otherwise, the fan stops working. Thus, the fan can be prevented from being in a constant working state, the temperature in the high voltage distribution box can be effectively reduced, and the service life of an electrical device can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electrical systems of automobiles, and in particular relates to a high-voltage power distribution box. Background technique [0002] The high-voltage power distribution box in existing electric vehicles generally adopts a sealed structure, which cannot completely discharge the heat generated by the current and electrical components when the high-voltage power distribution box is working normally; The cooling effect of the box is average, and the temperature in the high-voltage power distribution box and the life of the electrical components cannot be guaranteed. In order to solve the above-mentioned heat dissipation problem, the patent of the present invention adopts an active heat dissipation method to reduce the temperature in the high-voltage power distribution box and prolong the life of the electrical components. Contents of the invention [0003] The purpose of the present invention ...
