A plate-type heat exchanger and a method for manufacturing same are provided. A plate-type heat exchanger includes a first plate and a second plate which have flange parts vertically adhered by an adhesive, respectively. The flange parts are formed in a stepped shape and may thus increase an area adhered to the first plate and the second plate.

Plate-type heat exchanger and a method for manufacturing same

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.

Heat exchanger

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.

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.
