A bonded structure has a first bonded member with a first bonding surface, a second bonded member with a second bonding surface, and a bonding resin layer containing a polymer, disposed between the first bonding surface and the second bonding surface. The polymer in the bonding resin layer has polymer main chains oriented in an intersecting direction that intersects with the first bonding surface and the second bonding surface. The intersecting direction preferably extends along the thickness direction of the bonding resin layer. A heat exchanger has the bonded structure, and the first bonded member serves as a tubular member, and the second bonded member serves as a heat dissipation fin.

The invention relates to a manufacturing process for a heat dissipation heat sink composite having heat dissipation function and a manufacturing method for a finished product thereof. It comprises the steps of rolling a first heat conductive material and a substrate to adhere the first heat conductive material to the substrate for fixation; adhering a second heat conductive material to the substrate for combination; and rolling the second heat conductive material and the substrate for firmly combination and fixation to complete the manufacturing of a composite material.

A heat exchange element includes a countercurrent portion including a plurality of partition plates each having a planar shape and a plurality of spacer plates each having a corrugated shape in cross section. The partition plates and spacer plates are alternately stacked such that corrugation directions of the spacer plates are aligned. A side surface of the countercurrent portion is formed by end portions defined by bending portions in each of which the partition plate and the spacer plate are overlaid. Since the heat exchange element according to the embodiment of the present disclosure is configured as described above, the heat insulation between flow paths of the heat exchange element and the outside air is improved, and heat exchange between fluid in the flow paths of the heat exchange element and the outside air is reduced. Consequently, the heat exchange element achieves improved heat exchange efficiency.

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 sink for use in induction welding includes a number of tiles, wherein the tiles are electrically non-conductive and have a thermal diffusivity of greater than about 25 mm2/sec. A joint flexibly joins the tiles together.

Heat sinks containing polymeric protrusions on a base and optionally further including a foil or tape, as well as methods of making and using thereof, are described herein.

A heat transfer assembly includes a first plate, a second plate, and an engaging unit. The first plate has a first side and a second side, and the second plate has a third side and a fourth side. The third side is attached to the first side, which defines a sealed chamber between the first and second plates. The fourth side has an accommodating portion that is in thermal contact with at least a heat source. The engaging unit is disposed adjacent to the accommodating portion, and engaged with the heat source, thereby allowing the heat transfer assembly to be in direct contact with the heat source. Therefore, a lower thermal resistance can be achieved by the direct contact, and no penetration to the heat transfer assembly prevents the assembly from vacuum leaks.

Discussed is an adhesive containing a solid content, wherein the solid content can include cellulose, and carboxy methyl cellulose endowed with a carboxy methyl group.

A method provides a sealed connection of a connector to a heat exchanger of the coaxial tubular type is particularly suitable for a motor vehicle air-conditioning circuit. The method includes the steps of mounting a free end of an external tube of the exchanger in or on the connector. The external tube is directly secured with the connector, and an internal tube is inserted in the external tube until a free end of the internal tube is mounted in or on the connector. This mounting ensuring a sealing between the internal tube and the connector. The method further includes directly securing the internal and external tubes against one another to avoid relative displacements.

A thermal conductor includes a plurality of thermal conducting portions; and joint portions made of a material having flexibility and configured to join the respective thermal conducting portions with each other, having voids where neither the thermal conducting portion nor the joint portion is present, and satisfying a condition of 0.5[(S1S0)/S0]10020 when an area of the thermal conductor in a planar view in a first direction is expressed by S0 [cm.sup.2] and an area of the thermal conductor in the planar view in the first direction in a pressed state that the thermal conductor is pressed by 0.2 MPa in the first direction is expressed by S1 [cm.sup.2]. Accordingly, the thermal conductor satisfies both ensuring adhesiveness to a member in contact with the thermal conductor in use and suppressing excessive deformation of the thermal conductor in a compressed state.
