A condenser (100), comprising a shell (112), an inlet pipe (120), and an anti-impact plate (204). The shell (112) has an accommodating cavity (202). The inlet pipe (120) is a circular pipe having a gradually increasing inner diameter from the inlet to the outlet. The inlet pipe (120) is arranged to pass through the upper end of the shell (112), the outlet of the inlet pipe (120) being accommodated in the accommodating cavity (202). The anti-impact plate (204) is accommodated in the accommodating cavity (202), and the anti-impact plate (204) is positioned below the outlet of the inlet pipe (120). There is a gap between the anti-impact plate (204) and the outlet through which fluid flowing from the outlet can flow. The condenser (100) can reduce the friction loss and local resistance of the refrigerant gas flowing into the inlet pipe (120), such that the dynamic pressure of the refrigerant gas entering the condenser (100) is partially converted into static pressure, and reduce the static pressure loss of the refrigerant gas entering the cylinder from the inlet, thereby increasing the condensing pressure of the refrigerant gas in the condenser (100) to enhance the heat exchange performance.

The invention relates to an apparatus for desubliming, condensing or evaporating a fluid. The apparatus includes a chamber and at least one tubular member for desubliming, condensing or evaporating the fluid on the outer surface of the at least one tubular member. The chamber is provided with at least one inlet for the fluid and at least one outlet for the condensate and/or evaporate, and at least one supply and at least one discharge for a cooling and/or heating fluid. The tubular member includes an outer member and an inner member enclosed within the outer member. The inner member is in communication with the supply at a first end. The outer member is in communication with the discharge at a first end. The outer member is closed at a second end. The inner member is open and mouths into the outer member at a second end.

The group of inventions relates to heat exchange apparatus, and more particularly to condenser devices. The technological result of the group of inventions is that of reducing the risk of an increase in thermal resistance between the tube-side and shell-side heat transfer fluids of a shell and tube condenser. A condenser comprises a housing with tubes that have grooves on the outer surface thereof, baffles, and inlet and outlet manifolds for tube-side and shell-side heat transfer fluids. In contrast to the prior art, the tubes are coated on the outside with a material having a low wetting coefficient, and the distance between the baffles decreases from the shell-side heat transfer fluid inlet manifold to the shell-side heat transfer fluid outlet manifold. The condenser further differs from the prior art in that the tubes have protuberances on the inner surface thereof and are coated on the inside with a material having a high adhesion resistance coefficient.

An air thermal conditioning system, for at least one of heating air and cooling air, which includes a cross-flow heat exchanger array. The cross-flow heat exchanger array includes a plurality of planar membrane heat exchangers disposed in parallel with a space separating adjacent planar membrane heat exchangers. Each of the planar membrane heat exchangers include a first sheet; a second sheet coupled to the first sheet; and at least one fluid chamber defined by the first and second sheets, with the at least one fluid chamber extending between first and second ends of the planar membrane heat exchangers and opening to a first and second port at the first and second ends respectively.

A volatilized substance is condensed using a vapor-liquid interface. The volatilized substance is diffused into a condenser vessel containing a cooling liquid via a diffusion device. When the volatilized substance comes into contact with the cooling liquid it is condensed. The large vapor-liquid surface area created by the diffusion device enhances the rate of condensation. The cooling liquid is circulated through a heat exchanger to remove heat introduced by the condensing vapor. The temperatures of the cooling liquid leaving and entering the condenser vessel are monitored.

A projector includes first and second cooling targets and a cooling device. The cooling device includes a first compressor, a condenser, a first expander, a first evaporator configured to change the working fluid into a working fluid in a gas phase by using heat of the first cooling target, a heat exchanger including a first flow path through which the working fluid from the first expander flows and a second flow path, a second expander configured to decompress the working fluid from the first flow path, a second evaporator configured to change the working fluid flowing into the second flow path into the working fluid in a gas phase by using heat of the second cooling target, and a second compressor. The heat exchanger cools the working fluid flowing through the first flow path by the working fluid flowing through the second flow path.

Disclosed is a shell-and-tube heat exchanger type with a tube bundle and has a redistribution chamber connected to tubes of the tube bundle and to a duct. The duct extends between the redistribution chamber and the shell.

A heat exchanger tube with a tube axis, a tube wall and with ribs extending around on the tube outer side. The ribs have a rib foot, rib flanks and a rib tip, wherein the rib foot projects substantially radially from the tube wall. The rib flanks are provided with additional structural elements which are arranged laterally on the rib flank. First material projections, which extend substantially in the axial and radial direction, adjoin second material projections which extend substantially in the axial and circumferential direction of the tube, wherein the first and second material projections have a common boundary line. The axial extent of the first material projections along this boundary line is less than the axial extent of the second material projections.

Disclosed is an installation for generating electricity from a heat source, for disconnecting the production of electricity from the source of heat. The main characteristic of such installation is that it includes a thermochemical storage device coupled to a power cycle, the storage device consisting of a reactor in which produces a reversible sorption process and an evaporator and a condenser, at least one of the components of the thermochemical device being coupled mass and/or thermal to at least one element of the power cycle.

A plate for a heat exchanger between a first medium and a second medium, with a main plane of extension and a main longitudinal direction includes a first heat transfer surface, parallel to said main plane and in contact with the first medium; and a second heat transfer surface, parallel to said main plane and in contact with the second medium. The first surface includes a first medium inlet region, a first medium transfer region and a first medium outlet region including a first medium outlet port. The second surface includes a second medium inlet region, a second medium transfer region and a second medium outlet region, which second medium inlet region overlaps with the first medium outlet region and includes a second medium inlet port not overlapping, with the first medium outlet port. The first medium outlet region includes a protruding ridge extending from a respective edge of the first surface and perpendicularly to the longitudinal direction, and the protruding ridges form a barrier system for the first medium and define a channel along which the first medium is forced to travel, which channel runs first towards, then around and thereafter away from the second medium inlet port.
