Examples of the disclosure relate to vapour chambers. Examples of the disclosure can provide an apparatus comprising: at least a first vapour chamber portion and a second vapour chamber portion wherein the vapour chamber portions comprise walls housing an internal volume where the internal volume is configured to enable vapour flow; at least one hinge formed from walls of the first vapour chamber portion and walls of the second vapour chamber portion and configured to enable the first vapour chamber portion to be moved relative to the second vapour chamber portion; and wherein the hinge is thermally conductive and configured to enable heat to be transferred from the first vapour chamber portion to the second vapour chamber portion.

A heat exchanger includes flat tubes spaced apart from each other and located in parallel, a header that connects end portions of the flat tubes, and a fin joined between the flat tubes adjacent to each other. The fin is provided with a break line that breaks the fin when bending is performed. A cut is provided at both ends of the break line on the fin including a first end and a second end, and extends parallel to the airflow direction from the first end to the second end.

An automotive heat exchanger (10) has a heat exchanger core (12) including a header part (16) with a plurality of heat transfer tubes (38) and a head tank (20) with an opening receives end portions of the heat transfer tubes (38). A plastic header plate (18) is secured with the header tank (20) and header part (16). The header plate (18) includes a plurality of apertures (24) extending through the plate (18) that enable fluid passage. Each aperture (24) includes a cutout portion (28) that receives an end of a heat transfer tube (38). The cutout portion (28) has a complimentary shape to mate with the end of the heat transfer tube (30). A seal (50), in the cutout portion (28), seals the end of the heat transfer tube (28) with the header plate (18).

Provided is a heat exchanger which includes: a flat pipe as a heat transfer pipe in which refrigerant flows; and multiple fins having openings for inserting the flat pipe and arranged at a predetermined interval in a length direction of the flat pipe. At the flat pipe, multiple linear cutouts used for positioning the multiple fins are formed at the predetermined interval in the length direction of the flat pipe, and at least part of an edge of each opening contacts a corresponding one of the cutouts.

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 heat exchange system includes cooling tubes that carry coolant and are placed on an external surface of a storage tank, which may be spherical, cylindrical, or other shape. The storage tank may be a cryogenic rocket fuel tank. The cooling tubes are bent to particular radius of curvatures that correspond to the varying curvatures of the storage tank. A network of spacers and bridge brackets with adjustable setscrews are used to precisely place the cooling tubes in correct positions on the external surface of the storage tank. Once placed in the desired position, the setscrews are adjusted to maximize the surface area contact between the cooling tubes and the exterior surface of the storage tank, resulting in optimal heat transfer without overstressing the materials of the tubing or the storage tank. The precisely positioned tubes may then be permanently affixed to the exterior surface of the storage tank using a cryogenic adhesive.
