A heat exchanger has a core plate connected to a tank member by clamping claws. The tank member has a waved outer surface including outer ridge portions and outer valley portions which are disposed alternately. The tank member also has a waved inner surface including inner ridge portions and inner valley portions which are disposed alternately. The outer valley portions are capable of receiving the claws. The inner ridge portion is positioned inside the outer valley portion in a width direction. The inner ridge portion is positioned between the adjacent tubes and/or between extensions of the tubes in a height direction. An inner width of the tank member regulated by the inner ridge portions is narrower than a width of the tube.

A heat exchanger assembly is provided which includes a coaxial heat exchanger that is formed, at least in part, of a more corrosion resistant material such as, but not limited to stainless steel, titanium and/or alloys thereof. The assembly further includes a condenser tee connected at each end of the coaxial conduit or tubing defining the heat exchanger. The assembly allows for a non-brazed connection of the condenser tee to an inner tube of the coaxial heat exchanger. In some embodiments, the compression fitting may be connected directly to the heat exchanger without the use of a tee.

Disclosed are a heat exchange tube, a processing method for same, and a heat exchanger having same. The heat exchange tube (10a, 10b, 10c, 10d, 10e) includes a body portion (11a, 11b, 11c, 11d, 11e) provided with a plurality of flow channels (111a, 111b, 111c, 111d, 111e) arranged in parallel and spaced apart with each other, the length direction of the flow channel (111a, 111b, 111c, 111d, 111e) being parallel to the length direction of the body portion (11a, 11b, 11c, 11d, 11e); at least one side of the body portion (11a, 11b, 11c, 11d, 11e) is provided with an extension portion (12a, 12b, 12c, 12d, 12e) along the width direction of the body portion (11a, 11b, 11c, 11d, 11e); and the extension portion (12a, 12b, 12c, 12d, 12e) and at least part of the body portion (11a, 11b, 11c, 11d, 11e) are formed by folding the same plate material.

A heat exchanger includes: a heat exchange core portion; and a tank portion connected to the heat exchange core portion. The heat exchange core portion has a connection plate that surrounds a part of the tank portion from an outer peripheral side. The connection plate has slit-shaped openings arranged along an edge of the connection plate in a first direction. A part of the connection plate between each of the openings and the edge is deformable into a concave shape toward the tank portion. A part of the openings has a widened portion at both ends in the first direction. A width dimension of the widened portion in a second direction from the opening to the edge is larger than that of the other portion of the opening.

A heat exchanger has a collecting pipe, a separator and a number of heat exchange tubes. The collecting pipe has a pipe wall and an inner cavity. The separator is provided in the inner cavity. The separator extends along a lengthwise direction of the collecting pipe. The separator divides the collecting pipe into a first cavity and a second cavity. The heat exchange tubes are arranged along the lengthwise direction. Each heat exchange tube has a first end and an inner cavity. The first end of the heat exchange tube sequentially passes through the pipe wall of the collecting pipe, the first cavity and the separator to be inserted into the second cavity. The inner cavity of the heat exchange tube is communicated with the second cavity. As a result, uniformity of refrigerant distribution in the heat exchanger is improved.

A pressing method and a finished product thereof are provided. The pressing method includes the steps of: providing a heat conductive base (1), and defining a pressed zone (10) on the heat conductive base (1); forming a plurality of penetrated holes (100) arranged with intervals in the pressed zone (10), and forming a pressed part (101) between any two of the adjacent penetrated holes (100); and processing a pressing and extruding operation to the pressed part (101) for allowing the pressed part (101) to be pressed and extruded so as to be extended and deformed towards the adjacent penetrated hole (100) for filling the penetrated hole (100).

Heat transfer between a fluid-bearing flexible tube and a heat-conducting surface is improved by fixing a flexible heat-conducting sheath to the flexible tube and by compressive fixing that distorts the tube and deforms the sheath and/or the surface. The tube can be made of cross-linked polythene (PEX). The sheath can be spirally wound high-purity aluminum wire. The sheath enables efficient heat transfer between the outer surface of the tube and the heat-conducting surface. Applications include radiant heating and cooling. Tube layout can be customized and variable tube spacing is possible, for example by using a castellated layer to support the tube.

A heat exchanger may include a plate, a seal and a cover. The plate may have at least two receiving grooves having a respective groove base, an intermediate region disposed in a plane between a plurality of rim holes, and a ramp extending between the intermediate region and the respective groove base of the at least two receiving grooves. The seal extends in the at least two receiving grooves. The ramp may be rounded at a transition to the receiving grooves with a first radius and at a transition to the intermediate region with a second radius, and the ramp may be inclined between 20<<65 relative to the intermediate region or has an S-shaped progression. An inflection point of the plate may be arranged in a region from 10% to 80% of a height difference between the intermediate region and the respective groove base.

A heat exchanger for cooling a flow of charge air includes a heat exchanger core that is inserted through an aperture of a housing. A leak-free seal is maintained along the periphery of the aperture by the compression of a gasket between a top plate of the heat exchanger core and a planar bearing surface of the housing. Compression of the gasket is maintained by one or more deformable retaining members that are disposed against the top plate.

A heating or air conditioning system with a housing and with a heat exchanger located therein, wherein the housing constitutes an upper housing part and a lower housing part in which the heat exchanger is positioned, and the upper housing part forms, in the region where the heat exchanger is positioned, a housing wall that the heat exchanger is in direct contact with. The housing wall is designed to be elastic, at least in sections, such that the housing wall elastically yields in the contact region of the heat exchanger to compensate for dimensional tolerances of the heat exchanger.
