Abstract: A refrigerant evaporator includes: a first heat exchange part in which refrigerant flows to exchange heat with fluid to be cooled; a second heat exchange part arranged to oppose the first heat exchange part; a first tank arranged below the first heat exchange part to distribute the refrigerant to the first heat exchange part; a second tank arranged below the second heat exchange part to collect the refrigerant flowing through the second heat exchange part; and a third tank joined to the first tank and the second tank by brazing. A projection part is formed at one of joint portions between the first tank and the third tank. An insertion part is formed at the other of the joint portions between the first tank and the third tank, and the projection part is inserted in the insertion part.

Abstract: The disclosed method relates to manufacturing a heat exchanger which causes no brazing defects, and a heat exchanger manufactured by the method. The method relates to manufacturing a heat exchanger having an aluminum alloy tube defining a cooling-medium flowing passage and a copper alloy tube defining a water flowing passage, wherein a heat exchange is carried out between a cooling medium flowing through the cooling-medium flowing passage and water flowing through the water flowing passage. The aluminum alloy tube and the copper alloy tube are brazed to each other at a temperature of less than 548° C.

Abstract: A plurality of components of a refrigeration cycle are connected to a connection module. The connection module includes a body having a refrigerant flow path that constitutes a part of a refrigerant flow path in the refrigeration cycle. The refrigerant flow path includes a high-temperature-side flow path and a low-temperature-side flow path. The high-temperature-side flow path has a connection port to which a high-temperature-side component of the plurality of components, through which a high-pressure refrigerant of the refrigeration cycle flows, is connectable. The low-temperature-side flow path has a connection port to which a low-temperature-side component of the plurality of components, through which a refrigerant having a lower temperature than the high-pressure refrigerant flows, is connectable.
