A device for energy transfer and for energy storage in a liquid reservoir has a water heat exchanger arranged on a bottom and has an air heat exchanger arranged above the water heat exchanger, wherein the water heat exchanger is arranged in a liquid reservoir that is surrounded by an inner shell which delimits the device with respect to an outer shell covering the inner shell from the bottom, wherein the outer shell is at least partially inserted into an earth layer, and the device is closed upwardly by a lid in such a way as to make it possible to generate a flow of air from an air inlet to an air outlet of the air heat exchanger.

A heat exchanger including: rows of heat exchanging units that are superposed with one another in an air flow direction of the heat exchanger; and flat multi-hole tubes that extend from a first end toward a second of the heat exchanging units in a first direction in the heat exchanging units and that include gas-side flat multi-hole tubes. A refrigerant flows in the heat exchanging unit in the first direction. A number of the gas-side flat multi-hole tubes that are included in a front-most row heat exchanging unit on an airflow upstream side of the heat exchanger is less than a number of the gas-side flat multi-hole tubes included in a rear-most row heat exchanging unit on an airflow downstream side of the heat exchanger.

An interlaced heat exchanger is described. The interlaced heat exchanger includes a plurality of microchannel tubes configured to allow flow of a first fluid therethrough and a plurality of flat tubes configured to allow flow of a second fluid therethrough to exchange heat with the first fluid. The plurality of microchannel tubes and the plurality of flat tubes are stacked in an alternating arrangement along a longitudinal axis of the interlaced heat exchanger such that the plurality of microchannel tubes and the plurality of flat tubes are interlaced. The interlaced heat exchanger further includes a plurality of fin plates interspersed with the plurality of microchannel tubes and the plurality of flat tubes. The plurality of fin plates allows a flow of air across a width of the interlaced heat exchanger to exchange heat with at least one of the first fluid and the second fluid.

The present invention provides a finned heat-exchange system, comprising a heat dissipation chamber, a fin, an air guide element and a base, wherein the heat dissipation chamber is isolated from the outside, and both the fin and the air guide element are connected to the base; and the air guide element and the fin are in communication with the heat dissipation chamber through the base to dissipate heat from the inside of the heat dissipation chamber.

An exchanger system comprising two heat exchangers, a bypass line which extends between an inlet and an outlet, a line connected between the bypass line and a first orifice of each heat exchanger, a return line connected to two second orifices of the two heat exchangers and to the bypass line, three valves, and a controller which commands each valve alternately to open or to close. With such an arrangement, the intensities of the pressure peaks due to plugs are limited by distribution of the flow of the heat-transfer fluid in two parallel lines.

A refrigerator includes a storage space, an evaporator configured to cool air in the storage space based on heat exchange of a refrigerant, and a defroster configured to remove frost formed on the evaporator. The defroster incudes a pipe extended around the evaporator and including a circulation channel through which working fluid circulates, a fluid storage including a first opening and a second opening respectively communicating with opposite end portions of the pipe and configured to store the working fluid, and a pumping part disposed at a selected position on the circulation channel of the pipe between the evaporator and the fluid storage and configured to vaporize the working fluid to circulate the vaporized working fluid in the circulation channel.

A heat exchanger has: an inlet manifold having an inlet port; and an outlet manifold having an outlet port. A first gas flowpath passes from the inlet port to the outlet port. A plurality of plate banks are positioned end-to-end, each plate bank having a plurality of conduits with interiors along respective branches of the first gas flowpath, a second gas flowpath extending across exteriors of the plurality of conduits. One or more docks couple adjacent ends of the plurality of plate banks.

An exhaust gas recirculation heat exchanger assembly that includes a tube, a fin structure, and a clip. The tube has first and second walls extending between a first lateral end and a second lateral end. The fin structure is received in the tube to form a cooling tube assembly. The cooling tube assembly defines a first channel between the first lateral end and a first fin of the fin structure, a second channel between the second lateral end and a second fin of the fin structure disposed opposite the first fin, and a plurality of intermediate channels extending between the first and second channels. The clip is coupled to the cooling tube assembly. The clip has at least one flow impeding portion being configured to impede a fluid flow through at least one of the first channel, the second channel, and one or more of the intermediate channels.

A heat exchanger assembly includes a first internal flow path configured to channel a flow of fluid to be cooled from a first inlet to a first outlet. The heat exchanger assembly also includes a second internal flow path configured to channel a flow of a first coolant from a first inlet to a first outlet. The heat exchanger assembly further includes an external flow path configured to receive a flow of a second coolant proximate a surface of the external flow path.
