Abstract
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.
Claims17
A three-dimensional heat conducting structure, comprising:
- a vapor chamber having a casing and at least one through hole that is formed on the casing 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;
- and
- 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.
A manufacturing method of a three-dimensional heat conducting structure, comprising:
- forming a vapor chamber that includes a casing with at least one through hole;
- forming at least one heat pipe that has an open end, and inserting the open end into the through hole so that the heat pipe and vapor chamber are in fluid communication;
- applying laser welding process to gaps between the heat pipe and a rim;
- placing a welding ring on a joint position of the heat pipe and the vapor chamber so that the welding ring can enclose the rim;
- and
- applying a welding process to solder the welding ring to secure the connection between the heat pipe and the vapor chamber.
