Problems solved by technology
Previous tests on the heat dissipation capacity of the vehicle cooling system only tested the temperature and flow rate of a single test piece, or used multiple heat sources to test a single target parameter for different test pieces. Such tests completely ignored the differences between each test piece. The mutual coupling effect of the heat source, the measured results cannot truly reflect the heat dissipation capacity of the vehicle

The road test channel includes a heat exchange oil circuit and a circulation test medium circuit; the oil inlet of the heat exchange oil circuit is connected to the oil inlet main pipe, and the oil outlet of the heat exchange oil circuit is connected to the oil return main pipe; the test medium inlet and outlet of the circulation test medium circuit They are respectively connected to the heat exchange oil circuit; a valve is set on the heat exchange oil circuit to control whether the oil in the oil inlet main pipe is passed into the heat exchange oil circuit. The present invention can carry out integrated control of multi-target parameters for multi-channel test pieces and different working fluids in the thermal model identification process of the special vehicle cooling system under a unified heat source, and can precisely regulate the multi-channel target flow and temperature to meet the simulation requirements. The thermal test purpose of various test conditions of cooling systems with different configurations has strong engineering application performance.
Description
technical field [0001] The invention belongs to the field of vehicle engineering, and in particular relates to a multi-parameter target simulation test device under a unified heat source. Background technique [0002] The thermal model test of the cooling system of special vehicles is to simulate the heat of heat-generating components such as the powertrain of special vehicles, install the actual heat dissipation system in the simulated compact power cabin space, and study whether it can effectively take away the heat required by the powertrain. Whether the heat dissipation amount and heat dissipation distribution are reasonable can achieve the purpose of optimizing the layout of the power cabin and improving the ability of the special vehicle heat dissipation system, thereby verifying the designed heat dissipation system and shortening the design cycle. [0003] Due to the high power of special vehicles, the resulting compact structure and large heat dissipation, while the ...
