Abstract

In a three-dimensional heat conducting structure and its manufacturing method, the manufacturing method includes the steps of (a) providing a vapor chamber having at least one insert hole; (b) providing a heat pipe having an open end, and inserting the open end into the insert hole; (c) providing a support ring, and sheathing the support ring on a joint position of the heat pipe and the vapor chamber; and (d) providing a soldering means, and applying the soldering means between the support ring and the heat pipe.

First claim

What is claimed is:

1. A three-dimensional heat conducting structure, comprising:
a vapor chamber, including a casing, and at least one insert hole formed on a side of the casing and communicated with an interior of the casing;
at least one heat pipe comprising a cover and a capillary layer located inside the cover, the cover having an open end inserted into the at least one insert hole and communicated with the interior of the casing, a part of the cover being surrounded by the at least one insert hole of the vapor chamber;
a support ring, sheathed on the vapor chamber, the support ring and the casing of the vapor chamber being separate components, the support ring extending along an axial direction of the at least one heat pipe, the support ring having a contact surface facing toward an outer surface of the vapor chamber and a supporting surface opposite to the contact surface, and the contact surface of the support ring being in contact with the outer surface of the vapor chamber; and
a solder, disposed between the support ring and the at least one heat pipe, for combining the at least one heat pipe onto the vapor chamber, and a part of the solder being supported on the supporting surface,
wherein the vapor chamber has a rim formed around a periphery of the at least one insert hole and protruded from the outer surface of the vapor chamber, and an inner wall surface of the rim is in contact with an outer surface of the cover.

2. The three-dimensional heat conducting structure as claimed in claim 1 , wherein the support ring is sheathed on the rim of the vapor chamber, and an inner wall surface of the support ring is in contact with an outer wall surface of the rim.

3. The three-dimensional heat conducting structure as claimed in claim 1 , wherein the support ring is a ring made of a metal or heat-resistant non-metal material.

4. The three-dimensional heat conducting structure as claimed in claim 1 , wherein the support ring has a chamfer disposed on a side adjacent to the at least one heat pipe, and the solder stays between the chamfer and the outer surface of the cover without overflowing to the outer surface of the vapor chamber.

5. A three-dimensional heat conducting structure, comprising:
a vapor chamber, including a casing, at least one insert hole and a rim, the at least one insert hole formed on a side of the casing and communicated with an interior of the casing, the rim formed around a periphery of the at least one insert hole and protruded from an outer surface of the vapor chamber;
at least one heat pipe comprising a cover and a capillary layer located inside the cover, the cover having an open end inserted into the at least one insert hole and communicated with the interior of the casing, a part of the cover being surrounded by the at least one insert hole of the vapor chamber;
a support ring, sheathed on the rim of the vapor chamber, the support ring and the casing of the vapor chamber being separate components, the support ring extending along an axial direction of the at least one heat pipe, and a radial thickness of the support ring being larger than a radial thickness of the rim; and
a solder, disposed between the support ring and the at least one heat pipe, for combining the at least one heat pipe onto the vapor chamber,
wherein an inner wall surface of the rim is in contact with an outer surface of the cover.
