Embodiment Construction

[0026] The cooling packaging method of the vehicle-mounted liquid-cooled power electronic controller of the present invention can be combined with Figure 5 , Figure 6 described as follows:

[0027] a. Build an integrated case 1 that can integrate the DC / DC converter 2 and the DC / AC inverter 3, and set two closely adjacent DC / DC converters and DC inverters 3 in the case. The water tanks 11 and 12 of the / AC inverter; the upper mouth of the two water tanks is made to be suitable for installing the broadside of the DC / DC converter and the DC / AC inverter. If serial water cooling is used, a pair of water inlet and outlet ports shall be provided for the two water tanks, and a communication port for cooling water shall be provided on the partition between the two water tanks; For the water inlet and outlet.

[0028] b. Install radiators 4 on the lower parts of the DC / DC converter 2 and the DC / AC inverter 3 respectively to form independent DC / DC cooling modules and DC / AC cooling ...

Abstract

The invention provides a method for cooling and packaging a vehicle-mounted liquid-cooled power electronic controller. In the method, a DC / DC converter and a DC / AC inverter are respectively made into mutually independent DC / DC cooling modules and DC / AC cooling modules. , and integrated and installed in the integrated chassis to form an integrated integrated power electronic controller. Realized the integrated use of DC / DC converter and DC / AC inverter modular cooling package and power electronic controller, greatly saving the layout space of the power electronic controller in the car, and achieved the purpose of reducing volume and cost , improved cooling efficiency.

Description

technical field [0001] The invention relates to an automobile with all or part of the power energy provided by a fuel cell or a power battery, in particular to a cooling and packaging method for a vehicle-mounted liquid-cooled power electronic controller. Background technique [0002] Fuel cell vehicles generate high-voltage (above 200 volts) direct current through the fuel cell, and then convert it into variable-frequency alternating current required by the traction motor through the power electronic control system. Figure 1a Shown is a block diagram of the hybrid power system commonly used in fuel cell vehicles. [0003] Current fuel cell vehicles start relatively slowly and cannot reliably deliver fast dynamics. To make up for this defect, a power battery module (nickel metal hydride battery or lithium ion battery) is usually added. However, the output voltage of the fuel cell varies widely, and the voltage can usually reach more than 400 volts at no-load, while the vol...
