    The present invention relates to an assembly structure of a fixed seat and a heat conducting tube used for heat dissipation of an electronic device.

  Currently, in the heat conduction of electronic devices that generate heat, the heat industry uses characteristics such as high heat conduction ability, light weight, simple structure, and various uses of heat transfer tubes. Since this heat conducting tube can conduct a large amount of heat, it can greatly satisfy the heat conducting demand of electronic products. In addition, although the heat conducting tube is usually combined with a fixed seat, since the contact area with the electronic device that generates heat can be effectively expanded, whether the assembly structure of the fixed seat and the heat conducting tube is good or bad can be reduced. It has a direct influence on the stable fixing force. Therefore, how to improve the stable fixing force and the close joint between the fixing seat and the heat conducting tube is an important issue.

  A conventional assembly structure of a fixed seat and a heat guide tube includes a fixed seat and a heat guide tube. The fixed seat has a plate body, and a rectangular opening groove is formed at the bottom of the plate body. On the other hand, the heat conducting tube has a heat receiving end portion and a heat radiating end portion, the heat receiving end portion is disposed in the opening groove, and the heat radiating end portion is disposed above the plate body. One of the heat receiving ends is in contact with the inner wall of the opening groove, and the other is aligned with the bottom surface of the fixed seat.

  However, the assembly structure of the conventional fixed seat and heat conducting tube has the following problems in actual use.

  The inner walls on the left and right of the opening groove of the fixed seat are vertical, and after they are compression-bonded to the heat-conducting tube, the fixing force between them is quite small. If it is received, a phenomenon that the heat conducting tube and the fixing seat are loosened and separated occurs, causing problems such as inferior heat conduction ability and fixing force, and improvement has been awaited.

  The present invention has been made in view of these circumstances, and one end of the heat conducting tube is housed in the opening groove of the fixed seat, and is in contact with the opening groove, the extended portion, and the inner wall of the stopper. An object of the present invention is to provide an assembly structure of a fixed seat and a heat guide tube that ensures a stable fixing force and a close joint between the fixed seat and the heat guide tube, and further improves the overall heat transfer capability.

  In order to achieve the above-described object, according to one aspect of the present invention, an assembly structure of a fixed seat and a heat transfer tube includes a plate body and a heat transfer tube, and the fixed seat includes an opening formed in the bottom portion of the plate body and the plate body. Has a groove. The opening groove has a vertical through-hole penetrating the plate body, and an extended portion is formed on the inner wall of the opening groove. The width of the extended portion is larger than the width of the groove of the opening groove, and a stopper is formed at the inlet of the opening groove. The heat conducting tube has a heat receiving end and a heat radiating end. The heat radiating end portion passes through the through hole of the fixed seat and exits to the outside, and the heat receiving end portion is accommodated in the opening groove. One of the heat receiving end portions is in contact with the opening groove, the extended portion, and the inner wall of the stopper, and the other is aligned with the bottom surface of the fixed seat.

  The assembly structure of the fixed seat and heat transfer tube of the present invention prevents the phenomenon that the heat transfer tube and the fixed seat loosen and come off when subjected to an impact, and the stable between the fixed seat and the heat transfer tube. Fixing force and intimate joining can be ensured, and the overall heat conducting ability can also be improved.
