Description

  The present invention relates to a combination structure of radiators of an electronic device, and more particularly to a combination structure used for a heat dissipation unit.

  The periphery of a general electronic equipment body is covered with a case, and the inside is a sealed space. Electronic components and the like operate inside the sealed space. When the electronic equipment is in use, the electronic component emits thermal energy by executing its operation. Therefore, it is necessary to dissipate the thermal energy using a component having a heat radiation function such as a radiator for cooling separately. . Most of the prior art radiators are made of a metal material having a high thermal conductivity, and large radiators are usually made by a method such as casting or pressing. However, when producing a large radiator using the above-described production method, it is necessary to prepare a large mold. Since the cost of these molds and molds is very high and heavy, it is very inconvenient and uneconomical during production and transportation, so the following has been devised.

European patent EP0867937 “Sectional modular lamellar heat dissipator for electroic circuits” proposes a molding method by aluminum extrusion as shown in FIGS. A plurality of heat dissipating parts 11 are manufactured by using the heat dissipator 1 as a module unit, and the heat dissipating parts 11 are provided with parallel fins 1111 extending on a plane 111. A V-shaped depression 1112 is provided at a position corresponding to the opposite side of the fin 1111. When combining, the parallel fins 1111 of the heat dissipation component 11 are pressed against the V-shaped recess 1112 of the upper heat dissipation component 11 so that the parallel fin 1111 enters the groove of the V-shaped recess 1112 and deforms. The heat dissipating parts 11 are coupled to each other to form a stable coupling structure. However, there are still problems in actual use. The fin is pressed and deformed in the above assembly process, and is fixed inside the V-shaped recess. However, the stress concentrates on the neck where the fin stands up from the plane, and the V-shaped recess coupled to the fin Both are separated by tearing. In addition, the fin cannot be completely pushed into the V-shaped recess, and the gap between the two is not completely brought into close contact, resulting in insufficient heat conduction. Furthermore, it cannot deform | transform by applying external force to this fin, and an assembly operation cannot be performed again. Disadvantages of the prior art are: 1. Disengagement when the assembly structure ruptures. 2. After assembly, it does not adhere tightly and heat resistance occurs. 3. Stress tends to concentrate on the deformed part. 4. Lack of structural strength. 5. Rework work is not possible. In view of the above, further improvements were necessary.

  The main object of the present invention is to provide a combination structure of a radiator that saves costs and is fast and continuously coupled.

  In order to solve the above-described object, the present invention provides a combined structure of radiators, and is configured by combining a plurality of module radiating units with each other. Convex arm strips are provided on one end face of the heat radiating unit, and the convex arm strips are extended and installed in a pair of vertically oriented directions or a pair of diagonally upward directions. A tenon convex end is provided at the end of the convex arm strip, and a groove is provided at a corresponding position on the opposite side of the convex arm strip. A tenon groove is provided at the end of the groove. Since the tenon end is slid into the tenon groove and joined by fitting the convex arm strip into the groove, the heat dissipating unit is continuously and quickly coupled stably. To reach.

  The advantages of the present invention are as follows: 1. Simple structure and easy processing. 2. After assembling, they have the best bondability because they are firmly bonded to each other. 3. Quick assembly. 4. The structure is dense and the strength is high. 5. Low cost and high production efficiency.

  In order to clearly show the combined structure of the radiator according to the present invention, a detailed description will be given with reference to the drawings. As shown in FIGS. 3-6, the heat radiator 2 is configured by combining a plurality of module heat radiating units 2a with each other. A convex arm strip 211 is provided on one side 21 of the heat radiating unit 2a so as to extend, and the convex arm strip 211 extends in a pair of upward and outward vertical or inclined shapes. A tenon projecting end 2111 is provided at the end of the projecting arm strip 211 toward the inside or the outside of the projecting arm strip 211. A groove 221 is provided at a position corresponding to the opposite side surface 22 of the heat radiating unit provided with the convex arm strip 211, and a tenon groove 2211 is provided at the end of the groove 221. When connecting the heat radiating unit 2a to another heat radiating unit 2a, the convex arm strip 211 is fitted and combined in the groove 221 of another heat radiating unit, and the tenon convex end 2111 is further connected to the tenon groove 2211. By sliding in and joining, the heat radiating unit 2a can obtain a quick and stable coupling effect continuously with the other heat radiating unit 2a. Solves the problem caused by the combination of the prior art by the combined structure of the convex arm strip 211 on the heat radiation unit 2a, the groove 221 and the tenon convex end 2111 at the end of the convex arm strip 211 and the tenon groove 2211 at the end of the groove 221. As a result, the coupling effect between the heat dissipating units 2a can be more firmly stabilized.

  7 and 8 are structural sectional views of the third and fourth embodiments of the present invention. The tenon projecting end 2111 at the end of the projecting arm strip 211 extends in the inner direction of the projecting arm strip 211, and the same effect can be obtained.

A convex bar 212 is provided on the other side of the convex arm strip 211 of the heat radiating unit 2a, and a groove 222 is provided at a corresponding position on the opposite side surface 22 of the heat radiating unit provided with the convex bar 212. By combining the heat radiating unit 2a and another heat radiating unit 2a to fit the convex bar 212 into the groove 222 of another heat radiating unit 2a, it serves to fix the position.

  The detailed description of the present invention according to the above embodiments does not limit the scope of the present invention. Those skilled in the art can change, modify, and apply the shape and arrangement of the present invention. Even if these changes and adjustments are made, the significance of the present invention is not lost, and the scope of the present invention is not lost. include.
