Title: Heat exchanger and its manufacture
Inventor: MARUKASA SHIGEO
IPC: F28F1/32
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger which can be easily manufactured by improving the heat exchange efficiency and a method for manufacturing the exchanger. SOLUTION: This heat exchanger 100 comprises many refrigerant pipes 3 arranged in a zigzag shape in a staggered state with respect to the air supplying direction in such a manner that the fin pitch windward in the air supplying direction is wider than that leeward. Accordingly, since the pipes 3 are arranged in the zigzag shape in the staggered state with respect to the air supplying direction, the supplied air is disordered in the flow in contact with the refrigerant piped, and hence the heat exchange efficiency is improved. Since the internal of the fins arranged windward side is wider than that of the fins arranged leeward, frost is scarcely formed in bridge among the fins at the windward side, thereby making it possible to provided the efficient heat exchanger.
