Process for increasing the heat flow density of heat exchangers working with at least one high-velocity gaseous medium, and a heat exchanger apparatus for undertaking the process

摘要: A method and apparatus are disclosed for increasing the heat flow density of exchangers having at least one gaseous fluid flowing therethrough a high velocity. In form method, which may be used in motor vehicles, energy acceleration is taken from exhaust gases an internal combustion engine. this respect, gas exchanger vehicle interior heating, or cooling engine coolant, used. order to increase content gas, undergoes pressure build-up. The waste thus low loads, with relatively need heating. While loads small heating energy, but cooling, radiator. Preferably, system includes selectively operable build-up unit path gas.
