Temperature adjusting and air guiding device and battery box with same

Abstract

The invention provides a temperature adjusting and air guiding device, comprising an air guiding board, a fan and a mounting base for mounting the air guiding board. The air guiding board consists of a heat conduction ceramic substrate with air guiding holes, and an electric heating device integrally arranged inside or on the outer surface of the heat conduction ceramic substrate. The mounting base comprises a platy substrate and a cylindrical fan fixing base; the fan fixing base is provided with an air blower mounting hole; the end parts at two ends of the platy substrate are provided with fixing boards for fixing the air guiding board; and clamping structures for clamping the air guiding board are arranged at the corresponding positions on the opposite surfaces of the two fixing boards. When the air guiding board provided by the invention is in use, the air guiding board is arranged in a battery box and does not emit heat in a need of heat radiation, so that the air guiding board only has an air guiding effect. The air guiding board not only can guide air but also can heat after being electrified in a cold environment, so that an air heater and a structure for fixing the air heater can be saved. The air guiding board and the fan are arranged on the fixing base, so that the internal valuable space in the battery box can be greatly saved, and the manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to a battery box of an electric vehicle, in particular to an air guiding device in the battery box. Background technique [0002] In order to ensure the safety and service life of the batteries in the battery box, the battery box is equipped with a temperature-adjusting air guide device, which includes a fan, an air guide plate, an air heater and a temperature controller. This device ensures that each single battery is fully charged. Heat dissipation, however, the air deflector in the prior art can only guide the air flow, the air deflector is set separately from the special air heater, and the fan is also installed on an independent mounting base, which not only occupies a limited space in the box, but is also not easy to control, and Increased costs. Contents of the invention [0003] The object of the present invention is to provide a temperature-regulating air-guiding device to solve the problem in the prior art that the te...
