Heat exchanger i.e. refrigerant evaporator, for evaporating refrigerant in air-conditioning apparatus of motor car, has inflow pipe, and fluid gap interrupting connecting elements at inner and outer pipes that are bonded to each other

摘要

#CMT# #/CMT# The heat exchanger (1) has an inflow pipe (6) for introducing fluid into pipes (3) with an inner pipe (7) and an outer pipe (8). The inner pipe is arranged within the outer pipe such that a fluid gap is formed between the inner and outer pipes. An injection opening is formed on the inner pipe for directing the fluid from the inner pipe. An exhaust pipe (10) is provided for collecting flowing fluid from the pipes. The fluid gap interrupts connecting elements at the inner and outer pipes, which are mechanically bonded to each other. #CMT#USE : #/CMT# Heat exchanger i.e. refrigerant evaporator (claimed), for passing cooled or heated fluid, for evaporating refrigerant in an air-conditioning apparatus of a motor car. #CMT#ADVANTAGE : #/CMT# The heat exchanger enables maintaining the thickness of the gap containing the fluid, to remain unchanged irrespective of thermal and mechanical stresses of the inner and outer pipes, thus providing a uniform fluid gap with constant thickness during the operation of the heat exchanger, and hence improving cooling performance of the heat exchanger. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front perspective view of a heat exchanger. 1 : Heat exchanger 3 : Pipes 6 : Inflow pipe 7 : Inner pipe 8 : Outer pipe 10 : Exhaust pipe.
