The present disclosure generally relates to a heat exchanger (50) and a heat exchange unit (100) for the heat exchanger (50). The heat exchange unit (100) comprises: a plurality of plain fins (102) stacked perpendicularly to a first plane, such that a first fluid (104) is communicable through the first plane between the fins (102); and a plurality of tubes (112) for communicating a second fluid (110) therethrough for heat exchange with the first fluid (104), the tubes (112) extending perpendicularly through the fins (102), each tube (112) comprising an oblique cross-section (114) having a pair of opposing first sides (114a) and a pair of opposing second sides (114b). For each oblique cross-section (114), the first sides (114a) are perpendicular to the first plane and the second sides (114b) are angled approximately 60° to the first plane, the first sides (114a) being longer than the second sides (114b).

Disclosed is a receptor for receiving condensate from a v-coil heat exchanger (v-coil), the receptor having: a first channel having a first length defined between first opposing ends, the first channel configured to receive the v-coil; a second channel having a second length defined between second opposing ends, the second channel including: a first orifice intermediate the second opposing ends for receiving condensate from the first channel, the first orifice being fluidly connected to one end of the first opposing ends at a junction; and a fluid drain port at one or both of the second opposing ends.

A vapor/liquid condensation system includes a condensation unit and an evaporation unit. The condensation unit is connected with the evaporation unit via conduits. The evaporation unit has a liquid inlet, a vapor outlet and an evaporation chamber in communication with each other. The evaporation unit converts liquid-phase working fluid into vapor-phase working fluid, which spreads to the condensation unit. The condensation unit cools and condenses the vapor-phase working fluid into liquid-phase working fluid, which goes back the evaporation unit. After the vapor-phase working fluid enters the condensation unit, the vapor-phase working fluid is distributed and condensed into liquid-phase working fluid. Then the liquid-phase working fluid is collected and then goes back to the evaporation unit. The length of the pipeline is shortened and the pipeline pressure is lowered to avoid interruption of heat dissipation circulation and failure in heat dissipation.

A vapor-phase/liquid-phase fluid heat exchange unit includes: a first cover body having a first and a second side, a vapor outlet and a liquid inlet, the vapor outlet and the liquid inlet being in communication with the first and second sides; and a second cover body having a third and a fourth side, the first and second cover bodies being correspondingly mated with each other to together define a heat exchange space. A working fluid and a fluid separation unit are disposed in the heat exchange space. The fluid separation unit partitions the heat exchange space into an evaporation section corresponding to the vapor outlet and a backflow section corresponding to the liquid inlet. In the present invention, the conventional motor is replaced with the vapor-liquid circulation principle as the driving source of the working fluid so that the total volume is minified and the manufacturing cost is lowered.

A heat exchanger includes plate-shaped fins and a plurality of heat transfer pipes attached to the fins so as to intersect the fins. The heat transfer pipes are disposed at intervals in a long-edge direction of the fins. The fins have a wave shape at at least a portion thereof and are capable of expanding and contracting in the long-edge direction.

Hybrid additive featured plates used to form an overall microchannel heat exchanger and corresponding method of manufacture are disclosed. Various additive manufacturing (AM) techniques may be used to form walls defining microchannel features on a plate substrate. The manufacturing method is a hybrid process in that leverages both additive and conventional manufacturing techniques to minimize both cost and fabrication time.

An air conditioner includes a heat exchanger that is arranged in a ventilation flue inside a housing, wherein the heat exchanger includes a plurality of flat tubes, and a fin that includes a plurality of notch portions arranged side by side in a vertical direction, to which the plurality of flat tubes are inserted, and includes intermediate regions each formed between two of the notch portions adjacent to each other in a vertical direction, and a connection region connecting the intermediate regions to each other, first bulging portions that are at least partly positioned on the intermediate regions, and a second bulging portion that overlaps with a gap generated between the first bulging portions and the flat tubes.

A heat exchanger includes heat transfer tubes and a header that forms a refrigerant flow path. The header includes: a first member that includes a first plate-shaped portion; a second member that includes a second plate-shaped portion; a third member that includes a third plate-shaped portion positioned between the first plate-shaped portion and the second plate-shaped portion in a first direction that is a direction in which the first plate-shaped portion and the second plate-shaped portion are arranged; a fourth member that includes a fourth plate-shaped portion positioned between the first plate-shaped portion and the second plate-shaped portion in the first direction and a second opening that constitutes a part of the refrigerant flow path, where a second is along a longitudinal direction of the second opening; and a fifth member.

A heat exchanger is connected to a first pipe through which a refrigerant flows. The heat exchanger includes: heat transfer tubes; and a header connected to the heat transfer tubes. The header includes: a first plate-shaped portion connected to the first pipe; a second plate-shaped portion connected to the heat transfer tubes; a third plate-shaped portion disposed between the first plate-shaped portion and the second plate-shaped portion; and a fourth plate-shaped portion that is disposed between the third plate-shaped portion and the second plate-shaped portion and that has communication openings for the heat transfer tubes. The first plate-shaped portion, the third plate-shaped portion, the fourth plate-shaped portion, and the second plate-shaped portion are stacked and overlap in a stacking direction. The third plate-shaped portion has a refrigerant flow path formation opening including: a first region through which the refrigerant flows in a first direction perpendicular to the stacking direction.

The present disclosure relates to a heat exchanger. The heat exchanger includes: a plurality of tube panels including a tube elongated in one direction; a pair of header modules coupled to both ends of the plurality of tube panels; and a pair of header cases having an open side, providing a space therein, and having the header module inserted in the space such that the tube panels communicate with the spaces, in which the header modules is composed of a plurality of header blocks stacked and coupled to each other, and an insertion hole in which the tube panel is inserted is formed at each of the plurality of header blocks. Accordingly, it is possible to increase the efficiency of manufacturing a heat exchanger, manufacture a heat exchanger flexibly in a custom-made type in accordance with the size of a product having the heat exchanger, reduce tolerance due to brazing, and improve stability of a product.
