Title:
HEAT EXCHANGER AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2009222237
Kind Code:
A
Abstract:

To suppress increase of man-hour in a manufacturing process of a radiator 1.

With respect to the radiator 1, sidewall sections 53, 54 of core plates 5a (5b) are supported by supporting members 42a, of side plates 4a, 4b, when the core plates 5a, 5b, tubes 2, fins 3 and the side plates 4a, 4b are integrally joined by brazing in a furnace. Thus the sidewall sections 53, 54 are prevented from being opened due to heat in brazing. Accordingly, it becomes unnecessary to bend the sidewall sections 53, 54 to a bottom wall section 50 again after the brazing.
