- the projection formed on the brazing material supply member is bent to be locked on the tank side and the connector side, so that the tank and brazing material supply can be performed before brazing. Since the members and the connectors can be stably fitted, there is no danger that the brazing material supply member will fall off before brazing, and the work can be simplified.
- the fitting state between the brazing material supply member and the tank and the connector becomes stronger, so that the tank, the brazing material supply member and the connector can be more stably fitted. It is possible to be in the state of being combined.
- the protrusion formed on the outer peripheral edge portion of the tank is engaged with the groove formed on the brazing material supply member, and further, is engaged with the groove formed on the connector.
- the tank, the brazing material supply member and the connector can be stably fitted even before brazing, so that there is no possibility that the brazing material supply member will fall off before brazing, thus simplifying the work.
- Can be planned A hole extending toward the center is formed in the groove of the connector, and the tip of the protrusion may be bent inward to fit into the hole.
- the second projection formed on the partition portion of the tank is inserted into the hole formed on the brazing material supply member, and the second projection is further inserted into the hole. It is possible to prevent the connection between the different openings and the connection holes due to displacement at the time of brazing by crushing in the inside, so that the fitting between the tank and the brazing material supply member can be further appropriately and reliably performed. can do.
- the brazing material is clad on the surface of the heat exchanger tank in which only one of the entrance and exit portions is provided on one end face in the stacking direction of the heat exchanger tank.
- the brazing material can be supplied from the plate section between the tank and the pipe section of the connector even if it is not necessary, so that the connector formed by extrusion and the pipe section of the connector formed by cutting can be supplied. Is practically possible. Further, since the brazing material can be supplied from the plate portion of the connector, the brazing material cladding member and the brazing material supply member as the brazing material sheet can be dispensed with.
