Air-cooled electric vehicle controller

Abstract

The invention discloses an air-cooled electric vehicle controller, which comprises a hollow shell, a turbo fan, a front gasket, a front baffle, a rear gasket, a rear baffle, a screw, spring, and eighteen power tubes welded to circuit board. The invention is characterized in that an outer surface of the hollow shell is distributed with striped heat radiating fins; each heat radiating fins is added with two rows of bumps; a bottom of the hollow shell is square; a heat dissipation boss is arranged on the middle side of the hollow shell; and the heat dissipation boss is provided with a convex rib for mounting the spring piece. The air-cooled electric vehicle controller has the advantage that the spring is assembled to the ribs of the heat radiating shell to deform to produce elastic force, the elastic force is applied to a power tube body through pins of the spring piece to ensure that a power tube is tightly fitted with an inner surface of the hollow shell, and a heat conduction path is shortest. At the same time, the turbo fan in time takes away the heat generated by the power tube to ensure timely and effective heat conduction.

Description

technical field [0001] The invention relates to an electric vehicle controller, in particular to an air-cooled electric vehicle controller. Background technique [0002] With the development of society and the continuous increase of fuel vehicles, the shortage of natural resources such as petroleum fuels and the global warming caused by fuel emissions have become increasingly prominent. Therefore, in this context, hybrid or pure power vehicles have gradually entered people's lives, and electric vehicles have emerged as the times require. The controller is the core component of the electric vehicle. It controls the electric current of the motor to ensure the power required for the vehicle to run, and plays a vital role in ensuring the normal running and safety of the vehicle. Most electric vehicle controllers in the state of the art are power tubes arranged in a row, which are fixed on the side wall of the hollow housing through the transfer of aluminum bars, and one end of ...

AI Technical Summary

Problems solved by technology

[0003] The power tubes are distributed in a single row, and the heat generated by the power tubes is too concentrated during operation. In addition, the heat conduction path is too long when the heat is transmitted to the aluminum heat dissipation shell through the heat conduction aluminum strip, and the heat dissipation effect is poor. The power tube is burnt out and fails, and the controller function is lost

[0004] Affected by the quality of the thread on the heat-conducting aluminum strip, the locking force of individual power tubes and heat-conducting aluminum strips is small when the screws are locked or the wires are slippery, resulting in poor fit of some power tubes, and the heat of the power tubes cannot be effectively conducted out, causing some The power is burned out and the controller function is lost
