Claims

[Claims for Utility Model Registration] A tube having an outgoing and incoming path for refrigerant separated by a partition, and having an inlet and an outlet for the refrigerant at one end, is alternately stacked with fins and communicates with the inlet. In a heat exchanger in which a tank having an inlet tank part and an outlet tank part communicating with the outlet is connected to one end side of the stacked tubes, one end side of each of the tubes is inserted through the tank. an end plate having an insertion hole that abuts an end surface of the inlet or the outlet including at least the end surface of the partition wall on one end side of each tube inserted into the insertion hole; a sub-plate having a communication hole that communicates with the end plate; a tank that is joined to the end plate and defines a tank section together with the end plate; an inlet tank section that communicates the tank with the inlet of the tube; A heat exchanger comprising: a partition plate that partitions the tank into an outlet tank portion that communicates with an outlet of the heat exchanger;
