Abstract

The heat sink structure includes a vapor chamber, a heat pipe, and capillary elements. The vapor chamber includes a housing, a first capillary structure covering inside the housing, and a first working fluid filled inside the housing. The housing includes through holes and an inner top wall. Both ends of the heat pipe are inserted through the two through holes respectively and are exposed from the housing. The heat pipe includes a pipe body, a second capillary structure covering inside the pipe body, and a second working fluid filled inside the pipe body. Each of the capillary elements is connected to the inner top wall. One end of each of the capillary elements is in contact with the first capillary structure, and the other end of each of the capillary elements is in thermal contact with the heat pipe.

Claims (13)

1. A heat sink structure with a heat exchange mechanism, comprising:

a vapor chamber, the vapor chamber including a housing, a first capillary structure covering inside the housing, and a first working fluid filled inside the housing, the housing including at least a pair of through holes and an inner top wall;

at least one heat pipe disposed in the housing, two ends of the heat pipe being inserted through the two through holes respectively and exposed from the housing, the heat pipe including a pipe body, a second capillary structure covering inside the pipe body and a second working fluid filled inside the pipe body; and

a plurality of capillary elements connected to the inner top wall, one end of each of the capillary elements being in contact with the first capillary structure, the other end of each of the capillary elements being in thermal contact with the heat pipe.

2. The heat sink structure with the heat exchange mechanism of claim 1 , wherein each of the capillary elements includes an extending pillar extending downward from the inner top wall and includes a third capillary structure covering outside the extending pillar, and the first capillary structure and the third capillary structure are connected integrally with each other.

3. The heat sink structure with the heat exchange mechanism of claim 1 , wherein the housing includes an inner bottom wall, a plurality of support pillars extend from the housing and are disposed between the inner bottom wall and the heat pipe, and the first capillary structure covers outside each of the support pillars.

4. The heat sink structure with the heat exchange mechanism of claim 3 , wherein each of the support pillars is disposed corresponding to each of the capillary elements.

5. The heat sink structure with the heat exchange mechanism of claim 1 , wherein the housing includes an inner bottom wall, a plurality of support bodies extend from the housing and are disposed between the inner top wall and the inner bottom wall, and the first capillary structure covers outside each of the support bodies.

6. The heat sink structure with the heat exchange mechanism of claim 5 , wherein each of the support bodies includes a first protruding pillar extending downward from the inner top wall and includes a second protruding pillar extending upward from the inner bottom wall, and each of the first protruding pillars contacts against each of the second protruding pillars.

7. The heat sink structure with the heat exchange mechanism of claim 1 , wherein the two through holes are formed on two opposite side walls, two adjacent side walls, or the same one side wall of the housing.

8. The heat sink structure with the heat exchange mechanism of claim 1 , wherein the pipe body is in a linear shape, an L shape, a U shape, or a wave-like shape.

9. The heat sink structure with the heat exchange mechanism of claim 1 , wherein the two ends of the heat pipe exposed from the housing are inserted in a plurality of heat dissipation fins.

10. The heat sink structure with the heat exchange mechanism of claim 1 , wherein a plurality of heat dissipation fins formed by skiving the two ends of the heat pipe exposed from the housing.
