Structure and Method for Connecting Pipes of Heat Exchanger

摘要

Second pipes ( 2 Ha to 2 Hf) for circulating a fluid are respectively connected to a plurality of first pipes ( 1 Ha to 1 Hd) formed in a heat exchanger (R) or to a plurality of first pipes ( 1 Ha to 1 Hf) formed in and around the heat exchanger (R) . Groups (A to C) formed by arranging the first pipes ( 1 Ha to 1 Hf) in units of specified quantities (including a single pipe) along a vertical direction are formed in the state of being not overlapped with each other in a lateral direction of a vehicle.
