    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： Disclosed is a method for producing a heat exchanger. The heat exchanger comprises heat exchange tubes extending along a first direction and arranged along a second direction perpendicular to the first direction, and a fin. The fin is provided with fin grooves for mounting the heat exchange tubes, and each fin groove is provided with an opening on one side in a third direction perpendicular to the first direction and the second direction. The method comprises: providing a heat exchange tube preform, the heat exchange tube preform having a maximum size in a second direction; providing a fin preform, a fin groove of the fin preform having a minimum size in the second direction, and the maximum size being greater than the minimum size; inserting the heat exchange tube preform into the fin groove of the fin preform, so as to generate a predetermined contact pressure between the heat exchange tube preform and the fin preform by means of the elastic deformation of at least one of the heat exchange tube preform and the fin preform, and welding the heat exchange tube preform and the fin preform together.

    摘要： There is a need for better cooling solutions for the ever-increasing thermal density of computing systems. This is solved by providing a radiator (100) for a liquid cooling system for cooling a computing unit, the radiator comprising:
    - a first manifold (101) and a second manifold (102) having among them two liquid openings (103, 104) for connecting the radiator in a liquid loop,
    - channels (110) extending between the first manifold (101) and the second manifold (102) and providing parallel liquid paths between the manifolds (101, 102),
    - fin layers (130) sandwiched between sets of neighbouring channels (110) and extending between the first manifold (101) and the second manifold (102),
    - fastening means (120) for attaching a fan (10) to the radiator (100) in a predetermined position, determining a ring-shaped high-pressure zone (142) corresponding to an outer area of a fan radius (122) of an attached fan, where
    - at least one fin layer has a low-density section placed away from the high-pressure zone, and a high-density section being located in the high-pressure zone and having a higher fin density than the low-density section.

    摘要： Provided are a heat exchanger that makes it possible to supply air of an appropriate temperature to a plurality of blowing ports of an air-conditioning unit, an air-conditioning unit that comprises the heat exchanger, and an air conditioner. This air-conditioning unit 10 comprises a heat exchanger 20 that exchanges heat between air and a coolant, a blower 11, and an air outflow part 12. The heat exchanger 20 comprises a plurality of tubes 21 in which the coolant flows, an inlet header 23, an outlet header 24, and a fin 22. The inlet header 23 includes: a low-temperature-side coolant inflow part 231 into which coolant that has a relatively low temperature can flow; and a high-temperature-side coolant inflow part 232 into which coolant that has a relatively high temperature can flow. The low-temperature-side coolant inflow part 231 and the high-temperature-side coolant inflow part 232 are offset from each other in the direction D1 of the flow of air that passes through the heat exchanger and in an intersecting direction D2 that intersects the direction D1 of the flow of air.
