A refrigerator includes: a cabinet for defining a storage space and a machine room; a compressor disposed in the machine room; a machine room cover for shielding a machine room opening; a base pan in the machine room; a condenser including: headers mounted on the base pan and extending to intersect the base pan; a plurality of tubes connecting the headers; and heat exchange fins disposed between adjacent tubes; and fixing parts protruding upward from the base pan and fixing the condenser by restraining a lower end of each header, wherein insertion holes opened toward the machine room opening are defined in the fixing parts, wherein the condenser is able to move to pass through the machine room opening, and wherein the lower end of each header is inserted and mounted into each insertion hole and is separated by exiting each insertion hole by the movement of the condenser.

A double-sided roll bond condenser has a main body, an interposition section, and a neck portion. The main body is an upright board and has two side surfaces. Two filling structures are respectively protruded from the two side surfaces of the main body. The interposition section is formed at a bottom portion of the double-side roll bond condenser, and is a U-shaped folded structure. The U-shaped folded structure protrudes from one of the two side surfaces of the main body. The neck portion is located between the main body and the interposition section.

A stacked plate heat exchanger for a motor vehicle may include a plurality of elongated plates stacked on one another between which a plurality of cavities are disposed alternately for two media. The plurality of cavities may be respectively delimited by a respective plate of the plurality of plates zonally by a plate surface and a surrounding wall. The respective plate may include two flow openings, two passage openings, and two domes respectively arranged around one of the two passage openings. At least of one of the plurality of plates may further include an elongated separation shaping arranged on the plate surface, projecting into the respective cavity, and extending from the first short side between the two flow openings in a direction of the second short side. The separation shaping may adjoin the first short side at an angle α of 45° to 90°.

The present invention relates to a water-cooling type condenser, and more specifically, to a water-cooling type condenser including a fixing plate for fixing a gas and liquid separator, wherein the fixing plate is formed to enable a refrigerant and cooling water to flow by means of coupling between first and second plate portions, and is integrally formed, by brazing, with remaining components (a plate, a first inlet pipe, a first outlet pipe, a second inlet pipe, and a second outlet pipe), so as to enhance assemblability and durability and enable size reduction.

A distributor includes at least: a first flow path through which refrigerant flowing in from a refrigerant inflow unit flows in a first direction toward a heat transfer tube disposed on the side of a refrigerant outflow unit; two second flow paths branched from the first flow path; two third flow paths, through each of which the refrigerant flows in a second direction opposite to the first direction; two fourth flow paths, each of which is formed to protrude from a main body toward the second direction and through each of which the refrigerant flows in a third direction intersecting the two third flow paths; and two fifth flow paths, through each of which the refrigerant flows in the first direction.

A refrigeration system includes a compressor for compressing a gaseous refrigerant, such that the temperature and pressure thereof increases; a four-way valve controlling whether the refrigeration system is in a heating mode or a cooling mode; a condenser, in which the gaseous refrigerant from the compressor exchanges heat with a high temperature heat carrier, said heat exchange resulting in the refrigerant condensing; an expansion valve reducing the pressure of liquid refrigerant from the condenser, hence reducing the boiling point of the refrigerant; an evaporator, in which the low boiling point refrigerant exchanges heat with a low temperature heat carrier, such that the refrigerant vaporizes; and a suction gas heat exchanger exchanging heat between high temperature liquid refrigerant from the condenser and low temperature gaseous refrigerant from the evaporator. A balance valve is arranged for controlling the amount of heat exchange between the high temperature liquid refrigerant and the low temperature gaseous refrigerant in the suction gas heat exchanger by directing a flow of high temperature liquid refrigerant directly from the condenser to the expansion valve. Disclosed is also a method for controlling such a system.

An evaporator includes an inlet in a lower manifold, an outlet in an upper manifold, and a multiport tube extending between the lower manifold and the upper manifold. The multiport tube provides a flow path between the lower manifold and the upper manifold. One of the outer side walls of the multiport tube is provided with a first evaporator section with a first heat receiving surface and a second evaporator section with a second heat receiving surface, the first and second evaporator sections passing a heat load received via the respective first and second heat receiving surfaces to a fluid in said multiport tube. The first and second heat receiving surfaces form an angle with each other to align with and contact different surfaces of an object to be cooled.

An absorption refrigeration and air conditioning device capable of controlling temperature and/or the humidity of enclosed spaces particularly useful in maritime applications and improving fuel economy of internal combustion engines is provided.

A heat exchanger includes an inner fin arranged in a refrigerant passage. The inner fin has side wall portions formed so as to extend in a predetermined direction and arranged parallel to each other. A gap formed between the side wall portions facing each other is a passage portion through which refrigerant flows. Each of the side wall portions has a plurality of openings arranged in the predetermined direction. An inclined surface inclined with respect to the predetermined direction is formed in a part of the side wall portion located between the openings adjacent to each other.
