Abstract: A refrigerant evaporator includes: a first heat exchange part in which refrigerant flows; a second heat exchange part in which the refrigerant flows; 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 to introduce the refrigerant collected by the second tank to the first tank. A clearance is defined among the first tank, the second tank, and the third tank. At least one of a joint portion between the first tank and the third tank and a joint portion between the second tank and the third tank defines a drainage passage to discharge water trapped in the clearance.

Abstract: An attachment structure includes expansion valves used in a vehicle, and a housing to which the expansion valves are attached. The housing includes a flow path through which heat medium circulating in a heat pump cycle of an air conditioner of the vehicle flows, and the flow path is opened and closed by the expansion valves.

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.

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.
