Abstract: A cylindrical hole is formed between peripheral belt portions of two container constituent plates of a thermal storage material container of an evaporator with a cool storage function. A cylindrical portion of a thermal storage material charging member having a thermal storage material charging passage is disposed in the cylindrical hole and brazed to the two container constituent plates. That portion of the thermal storage material charging member which protrudes from the cylindrical hole includes a crushed portion and a cylindrical uncrushed portion. The crushed portion seals the thermal storage material passage. The cylindrical portion of the thermal storage material charging member is smaller in outside diameter than the uncrushed portion, and the cylindrical portion and the uncrushed portion have the same inside diameter. The cylindrical portion has an inward protrusion protruding into a thermal storage material containing space, and the inward protrusion has a radially expanding engagement portion.

Abstract: A cool storage material container is formed by brazing together peripheral edge portions of two aluminum plates. A cool storage material for storing cool is charged into a cool storage material accommodation space. The cool storage material container has a seal portion provided by closing a thermal storage material charging inlet which is formed at the peripheral edge portions of the two aluminum plates and is used to charge the cool storage material into the cool storage material accommodation space. The seal portion includes two outward protrusions which are formed by pressing and collapsing the thermal storage material charging inlet such that they project outward from the two aluminum plates and are brought into close contact with each other. The outward protrusions are bonded together by an anaerobic adhesive and are bent in the thickness direction of the aluminum plates such that their bent portions have a V-shaped cross section.

A flow prevention member is provided below the baffle plate so as to prevent flow of refrigerant from the second section into the third section. These two sections communicate with each other in a region above the baffle plate.

Abstract: A receiver-tank for use in a refrigeration cycle of this invention is provided with a filtering layer 435 formed so that an upper space 402 is formed above the filtering layer 435 in a tank main body 401. An upper end of a refrigerant outlet 441 in a tank bottom wall 421 is opened toward the upper space 402. The refrigerant flowed into the tank main body 401 from the refrigerant inlet 431 passes through the filtering layer 435 upwardly, and forms liquid-stagnation R in the upper space 402. The liquefied refrigerant of liquid-stagnation R flows out of the refrigerant outlet 441. Thereby, only the stable liquefied refrigerant can be extracted more assuredly.
