A heat sink cooling apparatus of the present invention includes a thickened Phase Change Material (PCM) and an aluminum profile container for superior cold storage, heat transfer and efficiency of defrost. The PCM is a composition including a brine solution and a thickening agent resulting in increased holdover capacity in a no-leak, safe food grade PCM, and a tubular aluminum profile manufactured with a highly conductive aluminum alloy, which can be triangular, with optional internal and/or external fin-tube configurations maximizing surface area for heat transfer. The heat sink cooling apparatus is capable of removing heat from (but not limited to) a transport cargo area (truck body) through the processes of conductive and convection heat transfer via the aluminum profile filled with a PCM, either in a passive form of cooling via free convection (hanging mount) or in a forced air plenum chamber.

A diffuser plate for a thermal transfer device can include a body having a number of first apertures and a second aperture that traverse therethrough, where the first apertures are asymmetrically arranged with respect to the second aperture. The first apertures can have a first shape and a first size, and where the first apertures are configured to receive a plurality of tubes. The second aperture has a second size, where the second size is larger than the first size.

A heat exchanger includes plural heat exchange units arranged in series in a flowing direction of external fluid. A tube of the heat exchange units has a tube body and a protrusion. A dimension of the protrusion in a tube stacking direction is smaller than a dimension of the tube body in the tube stacking direction. A dimension of the protrusion in an air flowing direction is larger than a thickness of the tube body. An outer fin is joined to both the upstream tube and the downstream tube arranged in the air flowing direction. The protrusion of the upstream tube is connected to an upstream end of the tube body in the air flowing direction. The protrusion of the downstream tube is connected to a downstream end of the tube body in the air flowing direction.

A connection between one end of a Multi Port Extrusion (MPE) tube (1) of aluminium or an aluminium alloy and one header (2), the connection comprises an adapter (3) with a seal ring (4) fixed between the MPE tube and the header. The invention also relates to a method for connecting said parts.

A cooling element and a method of manufacturing a cooling element. The cooling element includes a body having a surface adapted to receive a heat source, wherein the body is formed of extrusion profile having open ends. The cooling element further includes plugs attached to the open ends of the body to close the body, and a port for filling working fluid inside the closed body.

A tank for a heat exchanger includes an extruded tank section having a generally constant extrusion profile extending in a longitudinal direction from a first tank end to a second tank end. A first planar end cap is joined to the extruded tank section near the first tank end, and a second planar end cap is joined to the extruded tank section near the second tank end. Together, the extruded tank section and first and second end caps can at least partially define an internal tank volume. The first and second planar end caps are both arranged at non-perpendicular angles to the longitudinal direction.

A heat exchange assembly (1) for a heat exchanger, a heat exchanger comprising the heat exchange assembly (1), and a mold forming the heat exchange assembly (1) are provided. The heat exchange assembly (1) comprises: multiple heat exchange tubes (11) through which a heat exchange medium flows; a connecting plate (12) connected between adjacent heat exchange tubes (11); and a heat exchange plate (121) formed by at least one part of the connecting plate (12). The mold comprises: a first mold, the first mold forming holes (110) in the multiple heat exchange tubes (11); and a second mold (2), the second mold having a mold cavity (20) forming a main body of the heat exchange assembly (1), the mold cavity (20) having an opening (21), the heat exchange assembly (1) being extruded from the opening (21) of the mold cavity (20) of the second mold (2), and the opening (21) being strip-shaped and extending along a curved line.

The present invention relates to a boiler with a heating blower, the boiler being able to improve heat exchange efficiency without an additional boiler. According to the present invention, there is provided a heating blower that supplies high-temperature hot wind to a flame guide tube outside a storage tub, so it is possible to improve heat exchange efficiency of the flame guide tube and flue tube without an additional boiler.

A method of forming a component includes depositing a ceramic material within an open-cell void of a polymer body. The ceramic material deposited around the periphery of the open-cell void structure forms a thermally-conductive path through the polymer body. The ceramic material circumscribes an open volume extending the entire length of the thermally-conductive path that is filled with a sealant such that fluids are incommunicable from the first surface to the second surface via the thermally-conductive path. A method of forming a heat exchanger includes forming a plurality of plates, each plate formed as a thermally-conductive polymer body. The method of forming the heat exchanger further includes arranging the plurality of plates within a housing to form a plate and frame heat exchanger configured to place a first flowpath in a heat exchange relationship with a second flowpath.

A coaxial heat exchanger is provided. Embodiments of the present disclosure relate to a coaxial heat exchanger for use in water source heat pumps or other applications involving fluid to fluid heat transfer. Embodiments of the present disclosure allow for the use of pre-existing engineered tubing with a textured or riffled interior surface and a folded fin intermediate member. Some methods of the present disclosure involve annealing and hydrostatically expanding the engineered tubing to increase contact and thermal transfer between the inner tube and the intermediate member. Additional systems, devices, and methods are also disclosed.
