[Technical field to which the device belongs]

  The present invention relates to a radiation fin positioning structure, which has a particularly high density, Engagement positioning structure for heat radiation fins formed by stacking and connecting several metal pieces It is a device related to construction.

[0002]

[Prior art]

  With the rapid development of the computer industry, microprocessor chips The heating value of any electronic heating element is getting higher and the size is getting smaller. And efficiently dissipate those dense thermal energy to the outside of the system. In order to operate at a temperature that is acceptable for blocking electronic heat generation, Attaching heat radiation fins having a threshold area to the surface of the electronic heating element Thereby assisting in dissipating heat energy to the electronic heating element. That's it With such a method, it is possible to effectively grasp the execution life and service life of the electronic heating element. To

[0003]   Aluminum extruded type and die There are three types, such as cast molding type and folding type. Arminiu Machining capability for manufacturing heat radiating fins of extrusion molding type and die casting type Since the force is limited, its density (total heat dissipation area per unit volume) has a limit. Therefore, when they are used in electronic heating elements that generate even more heat, The volume or weight of the radiating fins also increases. In some cases it has the higher density, so the aluminum extrusion type And there is a tendency to overwhelm the die-cast type heat dissipation fins.

[0004]   Fig. 1 shows a conventional folding type heat radiation fin. The heat radiation fin 10a is made up of a plurality of metal pieces 11a by a mechanical press working method. Are pressed to a predetermined size, and the metal pieces 11a are made of copper or It is manufactured and molded from a metal material with favorable thermal conductivity such as aluminum. , The metal pieces 11a are formed in a "U" shape (or "L" shape), Each of them has a main body 12a, and the bent side portions 13 are parallel to each other on the upper and lower sides of the main body 12a. a are connected, and the metal pieces 11a are bent side portions 13a on the lower side of the body 12a. Is bonded to the heat dissipation base 20a by a method such as adhesion or welding. 20a is also made of a metal material having good thermal conductivity such as copper or aluminum Therefore, the heat dissipation base 20a can be easily attached to the surface of the electronic heating element, It assists in heat dissipation of the electronic heating element.

[0005]   In order to make the metal pieces 11a easily positioned relative to each other, Protruding pieces corresponding to the bent side portions 13a on the upper and lower sides of the metal pieces 11a. 14a and a concave hole 15a are formed, and the metal pieces 11a are formed by the protruding piece 14a and the concave hole 1a. The effect of positioning is achieved by mutual matching with 5a. However , The protruding pieces 14a of the metal pieces 11a and the recessed holes 15a cannot be joined gently, In addition, the closeness is not preferable, and therefore the metal pieces 11a are not easily loosened. If the metal pieces 11a collide with each other or fall unexpectedly, it is easy for those metal pieces 11a to The result is that it loosens or separates.

[0006]   FIG. 2 shows another conventional folding type heat radiation fin (Taiwan Patent Publication No. 4). No. 07753), and the heat radiation fins 30a are located at the upper and lower ends of the metal piece 31a. Protrusions are formed so that one or more sets of locking portions 32a extend vertically near both sides. All of the locking portions 32a are in the same direction and have a locking hook and a locking tank, Due to their structure, each metal piece 31a can be engaged and locked with each other. Become so. There is a predetermined distance when the locking hook and the locking tank are combined. Forming a gap and forming a groove-shaped airflow heat dissipation area, and the middle stage of the bottom end of the metal piece 31a. Elongated heat-conducting fins 33a are formed by bending so that they are oriented in the same direction on the locking portion and the locking portion. , Thereby forming a larger heat dissipation contact area during assembly.

[0007]   The metal pieces 31a of the heat radiation fin 30a are engaged with each other by the locking portions 32a. Can achieve the excellent positioning effect, but the locking portion 32a of those metal pieces 31a Still can not bond gently and the density is unfavorable. The piece 31a still slackens or decomposes.

[0008]   In the case of Taiwan Patent Publication No. 460110, "computer central processing unit" Proposal of "placed heat dissipation structure", mainly for assembling the heat dissipation piece (ie, metal piece) to the front and back Therefore, a plurality of heat dissipation fin sets can be formed, which is characterized by the upper and lower ends of the heat dissipation piece. The locking tank and the locking hook are formed to extend horizontally and heat is transferred in the direction orthogonal to the lower end. The fins are formed by bending. Among them, the locking tank is two from the heat dissipating body The legs are extended to form an almost "U" shape. It is homologous to the above, and the locking hook extends forward from the central part in the locking tank. The locking hook is formed on the projecting piece, and the dent is bent into a wave shape. The locking hook has a width that is slightly smaller than the width of the locking hole in the locking tank. The heat dissipation fins can be engaged with the tank holes, the heat dissipation fins can be engaged with each other in the front-rear direction, and the flow-guiding heat dissipation area in a groove-like arrangement And the heat conducting fins on the bottom side It forms a heat-conducting contact surface and contacts the entire heat absorption area of the bottom plate heat source.

[0009]   The radiating fins may be engaged with each other by a locking hook and a locking tub. Can achieve a better positioning effect, but the locking hooks and And the locking tank still cannot be joined gently, and the density is not favorable. These heat sinks may still loosen or decompose. .

[0010]   Therefore, as can be seen from the above description, in the case of the above-mentioned conventional heat radiation fin, Immediately improved due to obvious inconvenience and drawbacks in actual use There is a need.

[0011]
