Heat pipe fixing structure

A heat pipe fixing structure, in particular, a heat pipe fixing structure capable of fixing a heat pipe and a heat dissipating component thereof without welding.

The heat pipe is a tubular body made of copper or aluminum. Since copper or aluminum is a good conductor for heat conduction, it is widely used as a heat conduction element that directly contacts the heat source to conduct heat, and most heat pipes It is combined with other heat dissipating components through the stringing or stringing, but it will still be loosened and decomposed due to vibration during the handling process. Therefore, the prior art additionally uses heat paste and thermal paste to heat the tube and other The heat dissipating component is bonded, or the heat pipe is combined with other heat dissipating components by welding. Since the heat pipe is made of copper or aluminum, the material properties of the heat pipe are bonded or soldered through the solder paste, and the heat pipe and other heat dissipation are still not possible. Thermal resistance and environmental problems are caused by the combination of components or soldering.

In addition, there are also known techniques for combining a heat pipe with other heat dissipating components in a tightly fitting manner. Although the two methods can be used to fix the two, a part of the tight fitting structure needs to exert pressure on the heat pipe to deform it. When the pressure is applied to the heat pipe, the capillary structure inside the heat pipe is destroyed, so that the heat transfer efficiency of the heat pipe is greatly reduced or even dissipated, thereby losing the heat transfer effect of the heat pipe. Therefore, the lack of the prior art is a desire of those skilled in the art. The primary goal of improvement.

Accordingly, in order to effectively solve the above problems, the main object of the present invention is to provide a heat pipe fixing structure capable of providing a heat pipe to be firmly fixed.

In order to achieve the above object, the present invention provides a heat pipe fixing structure, comprising: a heat pipe, a carrier, and a first fixing member; the heat pipe has a body, and the body has a first side and a second a side surface; the carrier has a groove, the groove has an open side and a closed side, the heat pipe is disposed in the groove, and the first side and the second side of the heat pipe respectively correspond to the open side and the closed side The first fixing member is disposed above the heat pipe and the carrier, and one end of the first fixing member is in contact with the first side of the heat pipe.

The heat pipe fixing structure of the present invention can solve the shortcomings of the conventional welding and tight fitting, and effectively arrange the heat pipe and other heat dissipating components.
