As is well known, the air conditioner 1 comprises a blower unit 10 and an air conditioner unit 20.
An air mix door 24 sucks the inside air or the outside air by the blower 14 inside and cools and heats the air cooled by the evaporator (heat exchanger for cooling) 22 and the heater (heat exchanger for heating) 23 in the air conditioning unit 20. It mixes in a predetermined ratio and is blown out into the passenger compartment. The evaporator 22 is one element that constitutes a refrigeration cycle (not shown) and is operated by a compressor (not shown) driven by the engine.

Next, the detailed structure of the cold storage heat storage heat exchanger 100 will be described with reference to FIGS. The cold storage heat storage heat exchanger 100 is a cold storage heat exchanger here, has a front surface area substantially the same as that of the evaporator 22, and as shown in FIG.
It is composed of a tube 120 that accommodates the cool storage material 110 inside, and an outer frame 200 that holds the tube 120.

As shown in FIG. 3, the tube 120 is formed of two thin resin film materials (hereinafter referred to as film materials) 130 and 140 each having a slender rectangular outer shape.
On the film material 130 side, a bulging portion 132 that bulges toward the anti-welding side (the side opposite to the film material 140) inside the outer peripheral portion 133 (a portion corresponding to the side wall 131 of the tube) is provided. The bulging portion 132 corresponds to the reinforcing means of the present invention, and is easily formed from a flat film material by heat vacuum, heat press, or the like.
The film materials 130 and 140 are welded to each other at the outer peripheral portions 133 and 143 so that the regenerator material 110 is enclosed in the space formed by the bulging portion 132.

Here, the film materials 130 and 140 are used.
Has two layers of polyethylene terephthalate and ethylene vinyl alcohol. In order to improve the weldability, ethylene vinyl alcohol is provided on the surfaces of the film materials 130 and 140 facing each other. The plate thickness is set to be about 50 to 100 μm, and a predetermined thermal performance, that is, a thermal conductivity that allows cooling of air for a predetermined time or more by the cold heat of the regenerator material 110 enclosed inside is ensured. There is.

Further, as a concrete material of the regenerator material 110, a melting point thereof is 6 to 8 in order to prevent frost of the evaporator 22.
Paraffin of about ℃ is used. Paraffin is superior to molten salts and other inorganic substances in terms of scientific stability, toxicity, cost and the like.
