Patent attributes
An evaporation cycle heat exchange system for a vehicle is provided. The evaporation cycle heat exchange system is a new type of cooling system that cools vehicle electronic components, a fuel cell stack, an internal combustion engine, an automatic transmission, a turbocharger, etc. using an evaporative heat exchanger, thus improving cooling efficiency and reducing the size of components such as a radiator. The evaporation cycle heat exchange system cools coolant circulating through a vehicle cooling system by employing an evaporative heat exchanger in which a working fluid flows by a pressure difference caused by volume expansion and capillary phenomenon. Accordingly, it is possible to improve the cooling efficiency of the entire cooling system, reduce the size of components to comply with pedestrian protection regulations, improve fuel efficiency, and ensure the stability of the system. Moreover, the present invention provides an evaporation cycle heat exchange system for a vehicle, in which a product-integrated or line-integrated evaporative heat exchanger capable of being mounted in various vehicle components such as an inverter, a fuel cell stack, an oil fan of an internal combustion engine, a turbocharger, an automatic transmission oil fan, etc. is employed. Accordingly, it is possible to easily apply the evaporative heat exchanger to various vehicle components and various vehicle models, and thus it is possible to increase the degree of freedom of the design of the cooling system.
