[0002] The electronic control unit (ECU) of an automotive electric power steering system is the core of the EPS, primarily consisting of a motor and an ECU. Testing, verification, and calibration on a test bench are essential components of the development process. However, the heat generated and accumulated during continuous operation can overheat the ECU, significantly impacting its performance. Waiting for natural cooling reduces development efficiency, making reliable and effective cooling measures essential.

[0003] Existing cooling measures include using independent standing or table fans and temperature and humidity chambers outside the test rack. Independent fans require an external power source and suitable location, but the test racks were not originally designed with suitable space for fans. Temperature and humidity chambers are also very limited and are not suitable for every test rack.

[0004] Therefore, existing cooling measures have disadvantages such as low cooling efficiency, poor universality of use and certain risks of use.

[0005] Therefore, it is necessary to design an air-cooled heat dissipation device integrated on the EPS electronic control unit test bench to improve the heat dissipation efficiency and reliability of the test bench and avoid possible safety hazards. Summary of the Invention

A fan bracket is installed on one side of the fixed bracket, and a fan is installed in the center of the fan bracket, with the air outlet of the fan facing the motor.

[0008] The fixed base and the stand flange are connected by fastener one, which passes through a through hole one on the surface of the fixed base and is connected to a threaded hole one on the stand flange. The fixed base and the fixed bracket are connected by fastener two, which passes through a through hole two on the surface of the fixed bracket and is connected to a threaded hole two on the fixed base. The fan bracket and the fixed bracket are connected by fastener three, which passes through a through groove on the surface of the fan bracket and is connected to a threaded hole three on the fixed bracket. The fan and the fan bracket are connected by fastener four, which passes through a through hole three on the surface of the fan and is connected to a threaded hole four on the fan bracket.

[0009] The fastener 1 is an M10 bolt, and the fastener 2, fastener 3, and fastener 4 are M4 bolts.

[0010] There are three threaded holes three, and the line connecting the three threaded holes three is inclined relative to the edge of the fixing bracket.

[0011] The central angle between two adjacent fixed brackets and the center of the platform flange is 60 degrees.

[0012] The fixed bracket includes a connecting surface and a columnar structure. A hollow columnar structure is provided in the center of the connecting surface. One side of the columnar structure is a fan bracket mounting plane. The fan bracket mounting plane is provided with a wire harness mounting groove.
