Description

  The present invention relates to a heat radiating device having a heat conducting tube, particularly a heat radiating device that can be applied to a CPU or an electronic component, where the heat conducting tube is firmly positioned, and the heat radiating piece is fixed to the seat by a molding die press. At the same time, the heat conducting tube is firmly positioned between the heat radiating piece and the seat, and the positioning effect and the heat conducting effect are high. .

  As shown in FIG. 1, the conventional heat conducting tube and radiator are mainly joined by soldering the heat conducting tube 50 above the seat body 51 and penetrating a plurality of heat radiating pieces 52 into the heat conducting tube 50 for pressing. A single heat dissipation device is formed. According to this method, first, the seat body 51 and the heat conducting tube 50 are soldered, and the operation of penetrating the plurality of heat radiating pieces 52 through the heat conducting tube 50 is performed many times, and pressing is performed one by one to reach completion. However, in the soldering procedure, solder is applied to the joint surface between the heat-conducting tube 50 and the seat body 51, heated at a high temperature in a vacuum heating furnace, melted into the joint surface, further cooled, and then joined. This welding process is redundant, temperature and timing control is complicated, and toxic substances harmful to human body and environment are generated in the manufacturing process and contained in solder High concentrations of lead and other heavy metals are no longer used in the industry because they are harmful to the human body and the environment. Further, the procedure of pressing the heat-dissipating piece 52 and the heat-conducting tube 50 in combination is not only time-consuming and low in production efficiency, but also the coupling between the heat-dissipating piece 52 and the heat-conducting tube 50 is completely positioned due to the vibration of the press. It is difficult to obtain a bonding effect that is close together, and the defect rate is also quite high.

  In view of the above-described drawbacks, as shown in FIG. 2, a method of coupling the heat-conducting tube and the radiator by an insertion method is adopted. The heat conducting tube 60 is pierced from one side of the heat radiating piece 61, the heat conducting tube 60 is installed on the upper surface of the bottom plate 62 on the CPU (not shown in the figure), and the pressing piece 63 is bent. The heat generated by the CPU is held on the bottom plate 62 and conducted from the bottom plate 62 to the heat-conducting tube 60 and the heat radiating piece 61, and is released from the heat radiating piece 61 to the outside. However, since the heat conducting tube 60 is held on the bottom plate 62 by an insertion method, there is a considerable gap between the heat dissipating piece 61 or the bottom plate 62 and it is not tightly coupled, so that the heat resistance is high. The heat conductivity is low, the heat dissipation effect is low, and the heat conducting tube 60 is not closely installed, so that the effect itself cannot be exerted and needs to be improved.

  The main purpose of the present invention is a heat radiating device with a heat-conducting tube, of which a heat sink is composed of a combination of heat radiating pieces, and the molding and assembly of the heat radiating pieces are completed by independent fitting or pressing work.
