Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation equipment of a ground power system, and in particular to a separated power unit heat dissipation system. Background Art

[0002] The power unit cooling system consists of three parts: engine radiator, intercooler radiator and motor radiator. The current common cooling system of the power unit adopts an integrated installation form in which three radiators are stacked and installed on a bracket. When the cooling system is working, the flow path of the cold air passes through the first radiator (motor radiator and intercooler radiator) and the second radiator (engine radiator) in the order of stacking. The cooling gas entering the second radiator has passed through the first radiator and been heated. The intake temperature of the second radiator is higher than the ambient temperature, resulting in a decrease in the efficiency and effect of the second radiator. The heat dissipation efficiency of the second radiator cannot be fully utilized, resulting in a waste of resources, thereby reducing the output power of the power unit. This problem is particularly prominent in high temperature environments. Summary of the invention

[0003] The purpose of the present invention is to integrate and install multiple radiators in a stacked manner for the current common heat dissipation system of power units, so that the air intake temperature of subsequent radiators is higher than the ambient temperature, resulting in a decrease in the efficiency and effect of subsequent radiators, and the heat dissipation efficiency of subsequent radiators cannot be fully exerted, resulting in a waste of resources, thereby reducing the output power of the power unit. A separated power unit heat dissipation system is provided, in which each radiator is distributed at different positions of the cabin, and separated to ensure that the inlet and outlet air of each radiator is not affected by other systems, thereby achieving maximum heat dissipation efficiency to solve the above problems.
