The plate fin heat exchanger includes a plurality of plates arranged in parallel to define a plurality of flow passages there between, and a set of closure bars arranged at a first side of the plurality of plates to seal a first set of the flow passages against ingress of the hot flow, thereby directing the hot flow into a second set of the flow passages. Each respective closure bar includes an inner core formed of a first material having a first coefficient of thermal expansion and an outer cladding arranged about the inner core, the outer cladding formed of a second material having a second coefficient of thermal expansion. The first coefficient of thermal expansion is less than the second coefficient of thermal expansion.

A heat transfer apparatus includes an outer shell, an internal core body, and a flexible diaphragm extending from the core body to an interior surface of the outer shell. The shell includes a first inlet that receives a first fluid, a second inlet that receives a second fluid, a first outlet through which the first fluid exits the shell, and a second outlet through which the second fluid exits the shell. The core body forms first interior passageways that fluidly couple the first inlet with the first outlet and second interior passageways that fluidly couple the second inlet with the second outlet. The flexible diaphragm forms a flexible transition between each of the first inlet and the second inlet of the shell and the core body, and forms a seal that prevents the first fluid in the first interior passageways from flowing into the second interior passageways.

A system for power generation from renewable energy, comprising a heat exchanger within a subterranean formation. The heat exchanger comprises a casing at an upper portion of the wellbore, a tubular member extending through the casing to a lower portion of the wellbore, and fins in fluid communication with the casing and with the tubular member, the fins each comprising a volume defined by surfaces of the subterranean formation and configured to receive a fluid from the casing.

The cool storage material container includes a container main body portion joined to the refrigerant flow tubes. The outward projecting portion extends from an upper end of the leeward edge or windward edge of the container main body portion. The outward projecting portion has an expansion portion projecting from the container main body portion and projecting thickness of the expansion portion is greater than a thickness of the container main body portion. The expansion portion is located outward of the fins. At least one of left and right side walls of the expansion portion is so constructed to deform when an internal pressure in the cool storage material container increases beyond a predetermined pressure.

A fluidic thermal exchange element adapted to cool a heat generating component includes a thermal conductive element having a first surface that thermally contacts the heat generating component and a second surface having fins in a cell configuration. A cover is fluidically sealed relative to the thermal conductive element to form a cavity and has first and second fluid access points arranged relative to the fins such that cooled fluid flowing from the first access point to the second access point in the cavity interacts with the fins and acquires thermal energy therefrom to create heated fluid at the second access point. A modular radiator receives the heated fluid from the second access point and cools the fluid to create the cooled fluid for recirculation to the first access point. The modular radiator has a plurality of fluid-fluid thermal coupling elements (FFTCEs), each including first and second fluid thermal interface elements disposed in a frame. A plurality of the FFTCEs are stacked upon each other between top and bottom plates to mechanically restrain the FFTCEs, and the top plate comprises a first fluid access port for accepting the heated fluid and directing the heated fluid to flow through access channels in the respective frames of the FFTCEs to provide heat exchange with the respective FFTCEs to provide the cooled fluid at a second fluid access port that is connected to the first fluid access point.

A heat exchanger for an aircraft engine includes: a body including a plate-like first member and a plate-like second member that are stacked in a thickness direction of the first and second members and joined together, and a channel which is defined in the body and in which the cooling target fluid flows; and a corrugated fin plate disposed in the channel in the body. The body is bent along a curved surface to which the heat exchanger is attached. A plurality of heat dissipation fins stand on an outer surface of at least one of the first member or the second member.

Disclosed is a concrete box beam using a refrigeration stirrup, which may include a box beam, an evaporation pipe, a water inlet pipe, and a water removal assembly; the box beam is provided with a plurality of steel bars in a circumferential direction; the n evaporation pipe surrounds and is connected to an outer side of the plurality of steel bars and an input end of the evaporation pipe is higher than an output end of the evaporation pipe; an output end of the water inlet pipe is connected to the input end of the evaporation pipe, and the water inlet pipe is connected to a three-way valve; and the water removal assembly includes a water sealing cavity, the output end of the evaporation pipe is connected to the water sealing cavity by means of a recovery pipe, the water sealing cavity is connected to a first pipeline.

A tube used in a heat exchanger, wherein a tube body includes a curved end portion, a pair of parallel portions, a pair of inclination portions, and a fixed portion in which a long end part extending from one of the pair of inclination portions is bent to hold therebetween a short end part extending from the other of the pair of inclination portions, and the tube is a pipe member having a flattened shape in cross-section. Poor brazing is reduced by making the inclination angle of at least part of the other inclination portion with respect to the flat plate portion larger than that of the one inclination portion.

A refrigerator may include a cabinet defining a low-temperature storage space and a machine chamber in which a compressor and a condenser are disposed; and an evaporator disposed in rear of the storage space, wherein air flows upwards along the evaporator and thus cools down to lower a temperature of the storage space. The evaporator may include a cooling pipe in and along which refrigerant flows; and a plurality of cooling fins surrounding an outer face of the cooling pipe. The cooling pipe may be constructed so that the refrigerant flows downward along and in the cooling pipe.
