The heat exchanger comprises a first and a second stage (E1,E2), each having an inlet and an outlet of water, the second stage (E2) having an inlet and an outlet of oil, the first stage (E1) being provided with fuel inlet and outlet nozzles, selectively connected, in parallel, to the fuel supply to the engine (M). The inlet and outlet of water of the first stage (E1) are respectively connected to the outlet of the water radiator, by means of a cooling water circuit internal to the engine (M), and to the water inlet of the second stage (E2). The water outlet of the second stage (E2) is connected to the inlet of a water radiator, and the inlet and outlet of oil in the second stage (E2) are connected in series to a lubricant oil circuit internal to the engine (M).

A refrigeration circuit includes: a gas-liquid separator into which a gas-liquid two-phase refrigerant flowed out from a condenser flows, the gas-liquid separator being configured to separate the gas-liquid two-phase refrigerant into a vapor phase refrigerant and a liquid phase refrigerant; and a plate heat exchanger including a first heat exchanging part and a second heat exchanging part, the first heat exchanging part being a part where the vapor phase refrigerant flowed out from the gas-liquid separator and the liquid phase refrigerant flowed out from the gas-liquid separator exchange heat, the second heat exchanging part being a part where the vapor phase refrigerant flowed out from the first heat exchanging part and a returning refrigerant flowed out from an evaporator exchange heat.

A three-dimensional heat transfer device includes a vapor chamber and a plurality of flatten heat pipes. The flatten heat pipes are disposed on the vapor chamber and arranged along an extension direction of a short side of the vapor chamber. Major axes of cross-sections of the flatten heat pipes are parallel to a long side of the vapor chamber.

A heat exchanger is provided. The heat exchanger includes a target area that is a target for heat exchange; and a flow path structure. The flow path structure includes at least one inlet; at least one outlet; a first flow path connected to each of the at least one inlet and the at least one outlet, and extending along a first side of the target area; and a second flow path connected to each of the at least one inlet and the at least one outlet, and extending along a second side, different from the first side, of the target area.

Exemplary embodiments include an electronic display assembly for back to back electronic image assemblies. A first closed gaseous loop may encircle the first electronic image assembly while a second closed gaseous loop may encircle the second electronic image assembly. A heat exchanger is preferably positioned within the path of the first and second closed gaseous loop along with an open loop of ambient air. A circulating fan(s) may be used to force circulating gas around the closed gaseous loops. An open loop fan may be used to force ambient air through the heat exchanger and through an optional channel behind each electronic image assembly.

A heat exchanger in one aspect of the present disclosure comprises a plurality of plates and a fin. The fin comprises at least one first portion and at least one second portion. The at least one first portion is a wall surface that comprises at least one first opening. The at least one second portion, which is paired with the first portion, is a wall surface different from the first portion. The second portion comprises a second opening paired with a corresponding one of the at least one first opening. The fin comprises at least one opening pair, which is a pair of the first opening and the second opening. The at least one opening pair has a non-overlapping positional relationship in which the paired first opening and second opening are at least partially non-overlapping along a flow direction of a second fluid.

A heat exchanger in one aspect of the present disclosure comprises a plurality of plate parts. The plurality of plate parts is arranged such that respective outer surfaces of mutually-adjacent plate parts of the plurality of plate parts are in a non-contact state having a gap between the respective outer surfaces, and apexes, each of which is an apex of the at least one convex protruding from each of respective mutually-facing outer surfaces of the mutually-adjacent plate parts, do not face each other in an arrangement direction of the plurality of plate parts.

A structure for the end of pressure vessels, most applicably plate heat exchangers, for reducing the effects of movement changes and vibrations caused by variations in internal pressure and temperature. The end is made up of a heat transfer plate and an end part in such a way that the end part is connected by welding to the shell of the outer surface of the heat exchanger stack, forming an enclosed chamber on the end of the heat exchanger, into which chamber higher pressure than the external pressure level is brought and/or generated. The higher pressure receives and dampens, via a heat transfer plate, vibration and pressure shocks harmful to the heat exchanger structure in the medium circuits of the heat exchanger.

A heat exchanger plate for provides heat transfer between a first flow along a first flowpath and a second flow along a second flowpath. The heat exchanger plate comprised a body having: a first face and a second face opposite the first face; a leading edge along the second flowpath and a trailing edge along the second flowpath; a proximal edge having at least one inlet port along the first flowpath and at least one outlet port along the first flowpath; and at least one passageway along the first flowpath. Along a proximal portion, the first face and the second face converge at a first angle. Along a distal portion, the first face and the second face converge at a second angle less than the first angle.
