Heat pipe and base fixing structure

technical field

The invention relates to a heat pipe and base fixing structure, in particular to a heat pipe and base fixing structure which can greatly reduce production costs.

Background technique

With the development of electronic product technology, the volume of various chips (such as central processing units) is gradually reduced. Relatively, in order to enable various chips to process more data, chips with the same volume can accommodate several more chips than before. When the number of components in the chip is more and more, the heat energy generated by the components is also increasing. Taking a common central processing unit as an example, the heat generated during its operation is enough to make the entire central processing unit Therefore, heat dissipation devices for various chips have become an important issue.

Please refer to Figures 1A and 1B, which are cross-sectional views of the existing heat pipe and base fixing structure, including a base 10 and a heat pipe 11, the base 10 forms a concave at the center of the base 10 by aluminum extrusion processing The groove 101 has a continuous protruding portion 104 protruding upward from the two side walls 102 of the groove 101 , and the protruding portion 104 protrudes from the surface of the base 10 by a predetermined height. When the heat pipe 11 (which can be a round tube or a D-shaped tube or a flat tube) is placed into the groove 101, and the flattening process is performed to press the protrusion 104 toward the center of the groove, the protrusion 104 will It is pressed onto the top surface of the heat pipe 11 , and fills the width difference between the groove 101 and the heat pipe 11 to avoid gaps, so that the heat pipe 11 is firmly combined with the base 10 . However, a problem arises. In the planarization process, since the protrusions 104 are formed by vertically protruding upwards from the two side walls 102 of the groove 101, not all materials of the protrusions will Both will be deformed toward the opening of the groove 101, and some materials will still accumulate on the surface of the base 10 to form a raised platform. Due to the existence of the platform, it will affect the close contact with the heat source, resulting in reduced heat conduction effect.

In addition, the protruding part 104 is vertically extended upwards from the two side walls 102 of the groove 101, that is to say, the protruding part 104 is an additional material used, and this structure will lead to an increase in the manufacturing process. Disadvantages of production costs.
