A condenser for a refrigerator according the present invention includes a heat exchange unit configured to receive at one side thereof refrigerant, which has been compressed in a compressor, to perform heat exchange between the refrigerant and air and to discharge the refrigerant, which has exchanged heat with the air, to an evaporator, wherein the heat exchange unit includes a flat tube, through one end of which the refrigerant is introduced and through a remaining end of which the refrigerant is discharged, thereby performing heat exchange between the refrigerant and the air, wherein the flat tube includes at least one bent tube portion defining plural rows of tubes, which are spaced apart from each other in an up-and-down direction, and wherein the plural rows of tubes define an intersection bent surface, which has a predetermined curvature and intersects the up-and-down direction.

Condenser for refrigerator

A heat exchanger may include flat tubes formed of a microchannel type, and first and second fins positioned at a top and bottom of the flat tubes so as to conduct the heat of the flat tubes. The first and second fins may be respectively provided with first and second condensate water discharge fins at a top and bottom. The second condensate water discharge fins of the first fins and the first condensate water discharge fins of the second fins may come into contact, and the second condensate water discharge fins of the first fins and the first condensate water discharge fins of the second fins may be disposed in a line with respect to a vertical direction, thereby having an advantage of quickly transferring condensate water formed at the top to the bottom.

Heat exchanger

Provided is a heat exchanger. The heat exchanger includes a plurality of refrigerant tubes in which a refrigerant flows, a heatsink fin coupled to the plurality of refrigerant tubes to heat-exchange the refrigerant with a fluid, a header disposed on at least one side of the plurality of refrigerant tubes to define a flow space of the refrigerant and a guide device disposed in the header to partition the flow space, the guide device guiding the refrigerant from the header to the refrigerant tubes. The guide device includes a movable cover part.

A microchannel type heat exchanger may include a first heat exchanger and a second heat exchanger, in which a plurality of flat tube may be provided, a first path defined in flat tubes provided in the first heat exchanger, in which refrigerant flows in a first direction, a second path defined in flat tubes provided in the first heat exchanger, in which refrigerant, from the first path, flows in a second direction opposite to the first direction, a third path defined in the flat tubes provided in the first heat exchanger and a portion of the flat tubes provided in the second heat exchanger, in which refrigerant, from the second path, flows in a third direction opposite to the second direction, and a fourth path defined in the flat tubes provided in the second heat exchanger, in which refrigerant, from the third path, flows in a fourth direction opposite to the third direction.

Provided is a heat exchanger. The heat exchanger includes a plurality of refrigerant tubes in which a refrigerant flows, a heat dissipation-fin in which the plurality of refrigerant tubes are inserted and through which the refrigerant and a fluid are heat-exchanged with each other, a header coupled to at least one side of the plurality of refrigerant tubes to define a refrigerant flow space, and a guide device disposed within the header to branch the refrigerant into a plurality of passages corresponding to the plurality of refrigerant tubes.

Provided is a heat exchanger, which includes a plurality of tubes and a plurality of fins. The tubes accommodate respective refrigerant passages through which refrigerant flows. The fins having a plate shape are spaced apart from each other, and include a plurality of through holes through which the tubes pass, respectively. The fin is provided with a condensate water guide part guiding discharge of condensate water generated during heat exchange between air and the refrigerant flowing through the tube. Accordingly, adhesion of the tube and the fin is facilitated, the distance between neighboring fins is maintained, and condensate water is efficiently discharged.

A heat exchanger is provided. The heat exchanger may include a plurality of refrigerant tubes extending in a horizontal direction, at least one fin coupled to the plurality of refrigerant tubes, a vertically oriented header coupled to corresponding ends of the plurality of refrigerant tubes, the header distributing refrigerant into the plurality of refrigerant tubes, and a partition device that partitions an inner space of the header, the partition device including at least two through holes that guide refrigerant into the plurality of refrigerant tubes.
