The application relates to a heat exchanger having a block with ribs and rectangular tubes. The block is arranged between a first collecting box and a second collecting box. Each collecting box is closed off by a base which has eyelets for receiving the tubes, and a trough-shaped circulating section for receiving the collecting box extends along the edge of the base. The base has an elevated contact region on at least one end face for the tube which lies directly opposite the end face in order to allow a stable structure of the heat exchanger, collecting boxes, and block.

A cooling apparatus includes a cold plate including a lower surface to be in contact with a heat-radiating component, and a first coolant passage in which a coolant flows, a radiator including fins to perform cooling and pipes each defining a second coolant passage in communication with the first coolant passage, a pump to circulate the coolant, a first tank joined to one end of each of the pipes, and a second tank to join another end of each of the pipes to the pump. The radiator is provided on the cold plate, and the pump is adjacent to the second tank.

A heat exchanger includes: a header that extends in a first direction; and a plurality of heat transfer tubes that extend in a second direction crossing the first direction, each of which has one end connected to the header, and that are arranged in the first direction at intervals. The header includes: a header body having a tubular shape, a first member through which the one end of each of the heat transfer tubes extends, and a second member positioned between the header body and the first member in the second direction. The second member includes: a base portion that extends in the first direction, and a plurality of protruding portions that extend from the base portion toward the first member in the second direction.

Provided is a heat exchanger, including a plurality of heat exchange members arranged in a first direction so as to be spaced apart from each other. Each of the plurality of heat exchange members includes: a heat transfer pipe extending in a second direction intersecting with the first direction; and a heat transfer plate provided to the heat transfer pipe along the second direction. The heat transfer plate includes extending portions extending away from the heat transfer pipe in a third direction intersecting with each of the first direction and the second direction. The heat transfer plate is formed separately from the heat transfer pipe.

A heat exchanger is disclosed and includes a plate portion including a plurality of internal passages extending between an inlet and an outlet and at least one means for providing fluid communication between at least two of the plurality of internal passages.

A heat exchanger (1) includes a fluid collector (2) for receiving fluid, a multiphase distributor (3) for distributing fluid, a first flow path (4), and a plurality of multi-duct tubes (6), which each have a duct tube longitudinal axis (7) and which each lead into the multiphase distributor (3) and into the fluid collector (2) by forming an orifice (8, 9). A second flow path (5) leads respectively through the multi-duct tubes (6), the fluid collector (2), and the multiphase distributor (3), wherein the multi-duct tubes (6) extend through the first flow path (4) for the first fluid, so that the first fluid can flow around and the second fluid can flow through the multi-duct tubes (6).

A heat exchanger includes fins each housed in a respective one of tubes. Each of the fins includes a connecting portion that corrugated for a predetermined fin pitch and that has peaks joined to an inner surface of a wall of each of the tubes and a non-connecting portion that is not joined to the inner surface of the wall of the each of the tubes. The non-connecting portion has a length longer than the predetermined fin pitch. The wall of the each of the tubes has a protrusion to face the non-connecting portion.

A microchannel evaporator includes a plurality of microchannels. Each of the plurality of microchannels includes a first end and a second end. A first end-tank is coupled to each first end of the plurality of microchannels and a second end-tank is coupled to each second end of the plurality of microchannels. A second-fluid inlet is coupled to either the first end-tank or the second end-tank and configured to receive a fluid into the microchannel evaporator and a second-fluid outlet is coupled to either the first end-tank or the second end-tank and configured to expel the fluid from the microchannel evaporator.
