摘要： Examples of the disclosure relate to heat exchangers. The heat exchangers could be evaporators or condensers. The heat exchangers can comprise a plurality of structures extending from a base plate where adjacent structures are separated by at least a first distance. The heat exchangers can also comprise at least one cover plate positioned over ends of the plurality of structures so that the at least one cover plate is spaced from the ends of the plurality of structures by a second distance where the second distance is smaller than the first distance. The at least one cover plate is brazed to the plurality of structures by brazing material provided between the ends of the plurality of structures and the at least one cover plate. The brazing material is provided in a discontinuous configuration so that gaps are provided between portions of brazing material so that a brazing join is formed from brazing materials that has flowed into spacing between the at least one cover plate and the ends of the plurality of structures.

摘要： Examples of the disclosure relate to heat exchangers. The heat exchangers can comprise a plurality of channels configured for flow of working fluid. The plurality of channels can be configured to move between a non-expanded configuration and an expanded configuration such that, in the non-expanded configuration the plurality of channels are sized so as to allow for movement of the heat exchanger relative to one or more heat sources and in the expanded configuration the plurality of channels are sized so as to restrict movement of the heat exchanger relative to the one or more heat sources. The plurality of channels are configured so that changes in internal pressure of the working fluid causes the plurality of channels to move between the non-expanded configuration and the expanded configuration.

摘要： Examples of the disclosure relate to an oscillating heat pipe comprising for cooling components within a bendable electronic device. The oscillating heat pipe comprises at least one condenser region to be positioned in a first portion of the bendable electronic device and at least one evaporator region to be positioned in a second portion of the bendable electronic device. The oscillating heat pipe also comprises at least one bendable region provided between the condenser region and the evaporator region and configured to extend across a hinge of a bendable electronic device wherein at least one bendable region comprises a polymer tubing supported by a flexible helical support structure.
