Claims

[Scope of utility model registration request]

In a laminated heat exchanger in which a tank section is provided on one side of the heat exchange section by alternately stacking tube elements and corrugated fins and divided into two in the direction of flow of heat exchange air, the tank section The first stage tank part to which the refrigerant inlet pipe is connected and the final stage tank part to which the refrigerant outlet pipe is connected are respectively divided into two compartments in the stacking direction of the tube element and the fins, and the first stage tank part is connected to the first stage tank part. 1st and 2nd
A refrigerant inlet pipe is connected to the compartment and a refrigerant outlet pipe is connected to the first and second compartments of the final stage tank, respectively, and the refrigerant inlet pipe of one of the first and second compartments of the first stage tank is connected to the compartment. and the first part of the final tank section.
An on-off valve is interposed in the refrigerant outlet pipe of either one of the second compartments, and heat exchange air corresponding to each compartment is connected to the refrigerant inlet pipe and the refrigerant outlet pipe equipped with the on-off valves. A laminated heat exchanger characterized in that each passage portion is provided with a door for opening and closing the passage portion.
