A heat exchange tube (51) for a heat exchanger, heat exchanger and assembly method thereof. The heat exchange tube (51) is a combined heat exchange tube having a space (55) at its center, and the space (55) is configured to accommodate an insertion member (57), such that the combined heat exchange tube is expanded in and joined with a corresponding fin hole (53) in the heat exchanger. A heat exchange tube that is minute or has a small inner diameter can thus be expanded in a heat exchanger fin without employing a brazing process.

A bent pipe and a semiconductor refrigerator having the same are provided. The bent pipe for a fluid to flow therein includes a plurality of bent portions; a plurality of connecting pipe sections, each connecting two adjacent bent portions; and a retention member, which is successively fixed at different locations along the length thereof to the bent portions on the same side of the bent pipe. At least some of the pipe sections of the bent pipe can be kept in the bent shape by a retention member.

A counter-flow heat exchanger including a core region and a plenum region. The core region including a first set of heat exchanging passageways and a second set of heat exchanging passageways disposed at least partially therein. A plenum region is disposed adjacent opposed distal ends of the core region. Each of the plenum regions including a fluid inlet plenum, a fluid outlet plenum and a tube plate disposed therebetween. The first set of heat exchanging passageways is truncated and defines a first tube-side fluid flow path in a first direction. The second set of heat exchanging passageways defines a second tube-side fluid flow path in a second opposing direction. Each of the heat exchanging passageways extending from a fluid inlet plenum to a fluid outlet plenum. The tube plates and the core region include one of a cast metal formed thereabout each of the heat exchanging passageways or a braze bond formed between each of the heat exchanging passageways.

A case of a heat exchanging apparatus includes an opening section provided on the sidewall and a plate-like lid member for opening and closing the opening section. A heat exchange section of a heat transfer medium circulation pipe is fixed to the inner surface of a lid member via a frame body formed by combining bar-like members. When the lid member is at a position where the opening section is closed, the heat exchange section of the heat transfer medium circulation pipe is housed fixedly in the case, and when the lid member is at a position where the opening section is open, the heat exchange section of the heat transfer medium circulation pipe is withdrawn from the opening section out of the case. This can reduce labor for cleaning and maintenance of the apparatus effectively and improve efficiency of heat exchange of the apparatus.

Systems enhance stand pipe alignment and security with braces docking to the stand pipes. A link connects pairs of braces so the braces and stand pipes docked thereby cannot move relative to each other when fully secured. Partially securing braces allows adjustment of the braces and distance between the same and thus stand pipe position. Fully securing the braces makes the entire system rigid without need for a tie bar. Braces and links can be installed and secured to the stand pipes and among each other at an axial position from above the stand pipes, so that overhead, simple tooling may be used. A crimp nut or other resilient connector may be used to secure the systems from that single dimension with simple tooling. Any number of braces, joining to any number of other braces, may be used in the system, and several systems may be used at various levels.

The present disclosure relates to a heat exchanger. The heat exchanger includes: a plurality of tube panels including a tube elongated in one direction; a pair of header modules coupled to both ends of the plurality of tube panels; and a pair of header cases having an open side, providing a space therein, and having the header module inserted in the space such that the tube panels communicate with the spaces, in which the header modules is composed of a plurality of header blocks stacked and coupled to each other, and an insertion hole in which the tube panel is inserted is formed at each of the plurality of header blocks. Accordingly, it is possible to increase the efficiency of manufacturing a heat exchanger, manufacture a heat exchanger flexibly in a custom-made type in accordance with the size of a product having the heat exchanger, reduce tolerance due to brazing, and improve stability of a product.

The invention relates to a wound heat exchanger having a core tube extending along a longitudinal axis in an axial direction and having a tube bundle, which has a plurality of tubes for conducting a first fluid, wherein the tubes are wound about the core tube in a plurality of windings, the tubes being arranged in a radial direction perpendicular to the axial direction in a plurality of tube layers, adjacent windings of at least one tube layer having different axial distances in the axial direction and/or tube layers adjacent in the radial direction having different radial distances from each other in a cross-sectional plane perpendicular to the longitudinal axis. The invention further relates to a method for producing a wound heat exchanger and to a method for transferring heat between a first fluid and a second fluid by means of the heat exchanger.
