A heat exchanger including a pair of end plates, a plurality of flow plates sandwiched between the pair of end plates, and a plurality of heat transfer films that are respectively positioned between adjacent flow plates, and between each of the end plates and an immediately adjacent flow plate.

A vapor chamber with a support structure is provided. The vapor chamber with the support structure includes a first plate, a second plate spaced apart from the first plate, and multiple support elements fixed between the first and second plates. On an outer surface of any of the first plate or the second plate, laser welding is performed on positions corresponding to the support elements so as to join the support elements to the first and second plates and to form weld ports on the outer surface of any of the plates. The invention solves the problem of fixing the support structure inside the thin vapor chamber, and therefore mass production can be realized.

A heat transfer plate includes a first bar engagement comprising a first recess and a first edge portion surrounding the first recess, and a second bar engagement portion comprising a second recess and a second edge portion surrounding the second recess. A part of the first edge portion extends from a first plane to a parallel third plane, and a part of the second edge portion extends from the first plane to a fourth plane. The second and third planes are on the same side of the first plane, the third and fourth planes are a distance from the first plane, and the at least a part of the first edge portion projects from a front of the plate. An edge of the first edge portion defines a first area and an edge of the second edge portion defines a second area, the first area fitting inside the second area.

A thermal regulation device, especially for cooling an electrical component likely to give off heat during operation, more especially for an electrical energy storage module, the device including an upper plate and a lower plate assembled with the upper plate so that, together, the plates form a plurality of channels for circulating a heat transfer fluid; the device being such that least some of the channels open into at least one bend chamber by virtue of which the fluid can pass round a bend; and such that at least one of the bend chamber and the channels includes a mechanical reinforcing member formed on a wall of the bend chamber or of one of the channels, the reinforcing member being configured so as to improve the mechanical strength of the chamber and/or the channel with regard to potential deformation under the effect of a high pressure.

A flat tube for a heat exchanger, with two open ends defining its longitudinal direction, may include a first wall and a second wall which are flat and parallel to each other, thereby delimiting the inner space of the tube. The flat tube may include an inner fin located between the first and the second walls. One of the lateral sides of the first wall may include a main fold running along the longitudinal direction, wherein arms of the main fold form a slit facing the inner space of the tube, and the lateral side of the second wall is bent to cover the main fold.

A protection element for vapor chamber includes a main body and a protection element. The main body is divided into a working zone and a sealing zone. The sealing zone is located around an outer periphery of the working zone and is provided with a notch area, to which a fluid-adding and air-evacuating pipe is connected. The protection element is correspondingly mounted to the notch area to contact with the sealing zone of the main body. With the arrangement of the protection element, the fluid-adding and air-evacuating pipe is protected against collision and impact and accordingly, the main body of the vapor chamber is protected against vacuum and working fluid leakage.

A heat exchange member includes: a honeycomb structure including: an outer peripheral wall; an inner peripheral wall; and partition walls arranged between the outer peripheral wall and the inner peripheral wall, the partition walls defining a plurality of cells, each of the cells extending from a first end face to a second end face to form a flow path for a first fluid; and a covering member for covering an outer peripheral surface of the outer peripheral wall. In a cross section of the honeycomb structure orthogonal to a flow path direction for the first fluid, the partition walls extend in a radial direction. Each of the cells is formed from the outer peripheral wall, the inner peripheral wall, and the partition walls.

A heat exchanger including a pair of end plates, a plurality of flow plates sandwiched between the pair of end plates, and a plurality of heat transfer films that are respectively positioned between adjacent flow plates, and between each of the end plates and an immediately adjacent flow plate.

A heat dissipation device includes an upper cover, a lower cover, an upper wick, a first wick, a plurality of second wicks, a third wick, and a gas-liquid separation structure. The lower cover and the upper cover together form a sealed vacuum chamber therebetween. The upper wick is attached on a first inner surface of the upper cover and is in fluid communication with the second wicks and the third wick. The first wick is attached on a second inner surface of the lower cover. The second wicks are attached on the lower cover. Third wick is attached on a third inner surface of the lower cover and is connected to and in fluid communication with the first wick. The gas-liquid separation structure is attached on a planar area of the third wick so as to separate a vapor from a liquid in the sealed vacuum chamber.

A heat conducting part is provided. The heat conducting part includes a shell, including an inner layer and an outer layer, where a cavity is enclosed by the inner layer, and the outer layer wraps a periphery of the inner layer; a capillary structure, disposed in the cavity and abutting against the shell; and cooling liquid, located in the cavity, where the inner layer and the outer layer are made of different materials, and a material density of the outer layer is lower than a material density of the inner layer. In the heat conducting part provided in this application, a material with a relatively large density and a stable chemical property may be selected for the inner layer to ensure durability of the heat conducting part.
