A three-dimensional heat conducting structure includes a vapor chamber that has a casing with at least one through hole and is in fluid communication with an interior of the casing. At least one heat pipe having an open end that is inserted into the through hole and is in fluid communication with the interior of the casing. Further, a rim that is disposed on an outer surface of the vapor chamber, wherein gaps between the rim and the heat pipe are sealed by laser welding, and a welding ring is soldered to further secure the connection between the heat pipe and the vapor chamber.

The present application relates to a manufacturing method of a vapor chamber, including processing an upper cover and a lower cover into predetermined shapes; fixing a capillary structure on a surface of an inner chamber of the lower cover; injecting a working liquid into the capillary structure; and fixing the upper cover and the lower cover in a vacuum environment. The present application has an effect of more accurately control of a quality of the working liquid.

The present invention relates to a device for controlling the temperature of a component and a method of production thereof. The device includes an elongate basic profile that defines a plurality of fluid flow channels in its interior. The fluid flow channels are arranged in series and separated by webs. The elongate basic profile extrudes from a plastic material. The device includes a connection unit connected to the basic profile and designed to direct fluid into the basic profile or out of the basic profile. The connection unit is formed partially or completely from a transparent plastic material.
