ABSTRACT:
An active cooling circuit through which cooling liquid circulates, is connected to an evaporation heat exchanger for cooling said cooling liquid when it has begun to warm. For this purpose, a housing encloses an evaporation chamber into which an evaporation fluid, such as water, is sprayed whereby the heat needed for the evaporation cools the cooling liquid passing through a gap between an inner and an outer wall forming said housing. The active cooling circuit passes through the gap in which eddy bodies are arranged in such positions relative to the normal flow direction of the cooling liquid through the gap to cause eddy currents in the cooling liquid flowing through the gap for an improved heat exchange. The discharge for the evaporated fluid is located at the same housing end where the spray nozzles for the injection of the evaporation fluid are located.
