Abstract

A waterproof and dustproof self-radiating type motor-driven automobile direct current voltage changer comprises a radiating shell, a radiating cover plate, side sealing plates, a circuit board, a transformer, a coil, a Schottky diode and a field effect tube, wherein the circuit board is arranged in the radiating shell, the transformer, the coil, the Schottky diode and the field effect tube are respectively fixed on the inner side surface of the radiating shell, the radiating cover plate is fixed on the radiating shell in a sealing way, the side sealing plates are fixed at two ends of the radiating shell in the sealing way, and input-output lead bundles pass through a cable diminishing head and are led from the side sealing plates. As the changer adopts a completely-sealed structure, aluminum plates are coated on three surfaces of the transformer, and then the transformer coated by the aluminum plates are arranged on the radiating shell, motor-driven automobile direct current voltage changer with the structure not only solves the problem that the original automobile-mounted storage battery high voltage is converted to the 12V direct voltage, also can solve the problem of radiating of circuit elements and devices, and simultaneously is waterproof and dustproof; and the service life of the motor-driven automobile direct current voltage changer is prolonged.

Description

【Technical field】 [0001] The invention relates to a DC voltage converter for an electric vehicle, which belongs to a DC power voltage conversion device. 【Background technique】 [0002] Electric vehicle DC voltage converter is also called electric vehicle DC-DC voltage converter. It is a DC voltage converter that can convert the original high DC voltage of the electric vehicle battery into 12V. Due to the vehicle accessories such as headlights, wipers, fans, radios, airbags, electric windows and the interior of the car The power supply used by various instruments and other equipment is 12V standard DC voltage, and the battery voltage of electric vehicles is relatively high, generally 48V~90V. Therefore, a DC voltage converter must be equipped to convert the higher DC voltage of the battery. 12V DC voltage output to meet the standard DC voltage supply requirements of vehicle accessories. Since the output power of the DC-DC voltage converter of the electric vehicle is relativ...
