Title:
TANK FOR HEAT EXCHANGER, AND METHOD FOR MANUFACTURING TANK FOR HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2019/102763
Kind Code:
A1
Abstract:
This method for manufacturing a tank for a heat exchanger comprises: a mounting step in which the tank body is mounted to a die (5) in which cavities (510, 511) corresponding to packing are formed; and an injection step in which a material for the packing is injected into the cavities of the die to integrally form the packing on the bottom surface of a flange section. The die has formed therein an overflow passage (512) which is in communication with the cavities corresponding to the packing and into which an excess portion (342) of the material for the packing flows. In the injection step, in order that a gap formed around the overflow passage is closed, the packing is formed integrally on the bottom surface of the flange section while the die is pressed against a seal member (317) having lower rigidity than the die.
