Background

The heat source is usually arranged near the center of the electronic equipment, and it is difficult to lead out the heat generated by the heat source, so that a practitioner can clear heat by arranging a heat conducting and radiating element above the heat source, the heat conducting element is usually a heat pipe, a temperature equalizing plate, etc., the radiating element is a radiator, a radiating fin group, etc., and the heat conducting element is contacted with the heat source to absorb the heat generated by the heat source and then conducts the heat to the radiating element such as the radiator, etc., so as to clear heat.

Referring to fig. 5 and 6, a heat pipe 8 used for absorbing heat in the conventional heat dissipation module of the present invention must be fixed to a heat source by a joint with a base 9; however, for example, if the diameter of the heat pipe 8 is 10mm, the distance or width of the space or area for installing the heat pipe on the base 9 is about 30-60mm, and at most about 3-5 heat pipes can be installed on the base, and the joint portion between the two heat pipes is only one point or line contact, so as to increase the contact area between the heat pipe 8 and the base 9, the heat pipe 8 is pressed to be flat, and the flat heat pipe is laterally attached to the surface of the base 9, thereby increasing the contact area between the two heat pipes, but since the distance or width of the heat pipes that can be installed on the base is fixed or limited, the number of the heat pipes 8 is less than the number of round pipes before being flattened, and the obtained thermal efficiency may be the same or worse.

Therefore, how to increase the heat transfer efficiency of the heat dissipation module in a limited space and maintain a good thermal contact area to prevent the occurrence of thermal resistance is the first important objective of those skilled in the art.
