Description

  The present invention relates to a radiator, and more particularly to an annular radiator.

  A conventional cylindrical radiator includes a tubular body and a plurality of radiating fins coupled to the outer peripheral surface of the tubular body. A conventional method for joining the heat dissipating fins and the outer peripheral surface of the tube is as follows.

  The radiating fin planting and coupling method for a cylindrical radiator disclosed in Patent Document 1 and its application device are driven by a power source, and have a jig, a tubular body, and a radiating fin unit that gradually turn. The tubular body is disposed on a jig, and a plurality of concave grooves are provided on the peripheral surface. The radiating fin unit includes a plurality of radiating fins. A heat radiating fin unit is disposed on one side of the jig, and the tube rotates at intervals. When the concave groove and the radiating fin come to the opposite positions, the radiating fin is sequentially pushed out by the pushing device and inserted into the concave groove. When the radiating fins are inserted into all the concave grooves, the concave grooves and the radiating fins are coupled in the subsequent coupling process, the radiating fins are positioned around the outer periphery of the tube body, and the radiator is formed.

  The radiator coupling method disclosed in Patent Document 2 includes a heat conductive bottom seat, a radiation fin unit, and a forming jig. The bottom seat is provided with a plurality of concave grooves on the surface. A guide groove is provided between the concave grooves. The radiating fin unit includes a plurality of radiating fins. The forming jig has an inner space and a compression end. In the coupling step, first, the forming jig and the radiator are coupled, and the radiator is fitted into the inner space of the molding jig. When the compression end portion is inserted into the guide groove in the axial direction, the concave groove is pressed and deformed, and the deformed concave groove firmly fixes the radiation fin. This provides a better method than conventional crimping, effectively reducing punch or die board damage and improving yield, accuracy, and quality. It can also be applied to different types of radiators.

  The radiator coupling method disclosed in Patent Document 3 is that a plurality of radiation fins are coupled by a heat pipe or the like to an introduction portion (shape selectable) formed at the end of the radiation fin of the radiator. Form. A fitting groove formed by press molding is provided so as to face the joint surface of the bottom seat. The radiating fin of the radiating fin unit fits the introduction part into the fitting groove and presses the long concave groove provided at a distance from the fitting groove, so that the bottom seat and the radiating fin introduction part are tightly caulked. Become. By using the introduction part, the area where the radiating fin and the bottom seat are in contact with each other is greatly increased, and the thermal conductivity is effectively improved. It is easy to assemble by caulking, and it takes a long time to obtain a firm bond. There is no need for soldering, adhesive, etc., and it can be said that it is excellent from the viewpoint of ecology.

  A radiator having a heat pipe disclosed in Patent Document 4 includes a heat radiation module, a bottom seat, and one or more heat pipes. An introduction portion is formed at the end of the heat radiating fin, and a plurality of fitting grooves formed by press molding are provided on the upper surface of the bottom seat. When the introduction portion is fitted into the fitting groove, the caulking is firmly performed. One or more fitting grooves are provided in the lower surface of the bottom seat, the heat pipes are arranged correspondingly, and fit tightly when pressed flat. At the same time, since the bottom surface of the heat pipe is flattened, the heat pipe is flattened in the same manner as the bottom surface of the bottom seat and sufficiently contacts the heat source. Therefore, heat can be quickly radiated by the heat pipe.

The method of combining the heat dissipating fins and the concave grooves disclosed in each of the above patent documents by caulking, pressing the guide grooves on both sides of the concave grooves to deform the concave grooves and integrating with the heat dissipating fins is as follows. There was a problem. 1. Caulking is to use a pressing process that mechanically joins two parts. When the heat dissipating fin and the concave groove are joined by caulking, the contact portion is deformed to form a gap, which adversely affects heat conduction. 2. In addition to providing a groove on the outer surface of the tube, not only must a guide groove be provided, but also a space between the groove and the guide groove, the number of grooves on the limited surface area. However, the number of radiating fins is reduced. 3. The method of compressing the guide grooves on both sides of the concave groove and deforming the concave groove so as to be integrated with the heat radiating fin tends to spread outside the edge of the concave groove, and the heat radiating fin may come off. 4. The manufacturing process is complicated and the manufacturing time is long.
The radiator of the present invention has been devised to solve the above disadvantages.

Taiwan Patent No. 098105429 Taiwan Patent No. 0971515576 Taiwan Patent No. 095213607 Taiwan Patent No. 097104163 JP 2011-101005 A

A first object of the present invention is to provide a radiator that couples a radiating fin and a main body without using press working.
A second object of the present invention is to provide a radiator that is firmly coupled by increasing the coupling friction between the radiation fin and the main body.
A third object of the present invention is to provide a heat radiator that increases the number of heat dissipating fins with the same surface area.
A fourth object of the present invention is to provide a heat radiator that increases heat radiation efficiency.

In order to achieve the above-mentioned object, the present invention provides a heat radiator that improves these points. The radiator of the present invention has a main body and a plurality of radiating fins. The body has a first end and a second end. An axial direction is defined between the first end and the second end. A plurality of coupling grooves are formed on the outer peripheral surface. The plurality of heat radiating fins are coupled to the surface of the tube body, and at least one fitting protrusion corresponding to the coupling groove is formed at the end. When an impact is applied to the main body at a high speed by a machining method, the fitting protrusion of the radiating fin moves to the second end along the axial direction, and is quickly coupled to the coupling groove to be integrated.

  The radiator of this invention can couple | bond a radiation fin and a main body without using press work by the fitting of an introducing | transducing part and a fitting protrusion. By providing unevenness on the surface of the coupling groove, it is possible to increase the coupling friction between the heat dissipating fin and the main body and to achieve a firm coupling. Regardless of the press work, since the fitting is used, the surface area is not wasted, and the number of heat radiation fins can be increased by fully utilizing the surface area. Since the radiating fin and the main body are tightly coupled, it has suitable heat conduction and can improve the radiating efficiency. Due to the coupling by fitting, the cost is low and the manufacturing time can be reduced.
