A plurality of openings in the first fluid conduit fluidly couples the first fluid conduit to at least a first portion of the plurality of tubes. A first end of a second fluid conduit is arranged generally centrally within and parallel to the first fluid conduit. Refrigerant vapor is configured to flow through the second fluid conduit. Liquid refrigerant is configured to flow between the first fluid conduit and the second fluid conduit to at least the first portion of the plurality of tubes.

A liquid receiver of a condenser has a liquid receiver main body and a plug removably fitted thereinto. The liquid receiver main body has a refrigerant inflow hole into which refrigerant flows from a condensation section and a refrigerant outflow hole from which refrigerant flows into a supercooling section. The liquid receiver has a first space formed above the upper end of the plug and communicating with the refrigerant inflow hole and a second space formed below the upper end of the plug and communicating with the refrigerant outflow hole. The plug has a flow passage which is open to the first space and the second space at opposite ends. The first-space-side opening of the flow passage is located below the refrigerant inflow hole. The flow passage has a throttle portion whose cross-sectional area is smaller than a hole area of the refrigerant inflow hole.

According to the present invention, a heat exchanger comprises a plurality of coolant tubes and a coolant guide having a coolant flow path through which the plurality of coolant tubes communicate with each other, wherein the coolant guide includes a plurality of plates facing each other, wherein the pair of plates, respectively, include coolant flow path units formed facing each other, the coolant flow path unit forming the coolant flow path, and wherein the pair of plates, respectively, further include joining parts that come in surface contact with each other. Accordingly, the number of parts of the coolant guide may be minimized, and the structure of the heat exchanger may be simplified.

A heat exchanger and a method for additively manufacturing the heat exchanger are provided. The heat exchanger includes a housing defining a heat exchange plenum having a first fluid inlet and a first fluid outlet separated along a transverse direction. A plurality of heat exchange banks pass through the heat exchange plenum between a top side and a bottom side of the housing substantially along a vertical direction, each of the heat exchange banks comprising a plurality of heat exchange tubes. A plurality of collector manifolds are positioned at the top side and the bottom side of the housing, each collector manifold defining one or more connecting ports providing fluid communication between adjacent heat exchange banks.
