Abstract
An internal heat exchanger for an automotive air conditioner which is capable of securing length of the internal heat exchanger necessary for heat exchange by a double pipe even when an evaporator and an expansion valve are disposed where the distance to a partition wall is short. Between an expansion valve and evaporator, and a partition wall, a first double pipe is disposed which is formed by surrounding an inner pipe connected to an inlet port of the expansion valve with an outer pipe connected to an outlet port of the evaporator, and a second double pipe is disposed within an engine room which is formed by surrounding an inner pipe with an outer pipe, in a manner extended from the first double pipe. The first double pipe and the second double pipe are connected by a pipe connecting member such that the connecting portions of the pipes are prevented from disconnection.
