Heat exchanger for flammable refrigerants

摘要

The present invention relates to a heat exchanger for combustible refrigerants, the heat exchanger preferably for a railway vehicle, the heat exchanger having a hollow cuboidal housing, in which refrigerant lines are located, the refrigerant The lines are designed as tube-and-fin packs or tube-in-tube and fin packs. The hollow cuboidal housing is provided with pins on the inside of the closed side, at least part of the outside of the closed side being operatively connected to the passenger compartment. The problem addressed by the present invention is to create a heat exchanger of such a type that allows the existing safety risks of previous heat exchangers to be avoided, so that secondary circuits can be omitted and a direct system can be implemented instead. The hollow cuboidal housing is designed as a module which can be separated from the passenger compartment in an airtight manner, wherein only permanently sealed sections of the refrigerant lines are located inside the hollow cuboidal housing, and the connection points of the refrigerant lines are each completely, at least one sealing frame and/ Alternatively, at least two sealing plates are provided in the hollow cuboidal housing, the problem is solved.
