A heating element is attached to one surface 1a of one side, and an appropriate number of vertical plates 2, 2 and engaging grooves 3, 3 are equidistant from each other on the other side 1b of the substrate 1, and Install in parallel with each other. The cross-sectional shape of the thickened tip of the vertical plate 2 and the cross-sectional shape of the engaging groove are relatively matched.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat sink structural unit.

[0002]

[Prior art]

 In a conventional heat sink, for example, as disclosed in Japanese Patent Laid-Open No. 3-40460, a large number of fins are soldered on one surface of an aluminum base plate so as to be parallel to each other, and cut-and-raised parts provided on the fins are The structure is such that it abuts adjacent fins and maintains the space between the fins.

That is, after the base plate and the fins are obtained in a separate process, they are fixed to each other by solder plating by ultrasonic vibration to obtain a heat sink, which serves as a unit for constituting a heat sink. There is no.

[0004]

[Problems to be solved by the device]

 The heat sink of the above-mentioned conventional example has a heat generating element attached to one surface of the heat sink to achieve a heat radiating effect by fins. However, if the heat sink is formed of a cylinder and forced air is blown through the cylinder, the heat radiating effect is further improved. It is thought that it is possible to provide an excellent heat sink, and the present inventor has considered forming the tubular body from an aluminum extruded shape member and making it into a heat sink with an appropriate length. It has been found that the corresponding mold requires a corresponding cost, its size is limited, and an expensive mold must be prepared for various sizes.

The present inventor has paid attention to such a point and devised the present invention for the purpose of obtaining a cylindrical heat sink that can suppress the manufacturing cost as low as possible.

[0006]

[Means for Solving the Problems]

 An appropriate number of vertical plates and engaging grooves are provided at equal intervals and parallel to each other on the other surface of the substrate on which the heating element is mounted on one surface, and the thickness of the vertical plate is increased. The cross-sectional shape of the front end portion and the cross-sectional shape of the engaging groove are relatively matched, and one side end of the substrate is provided with a connecting plate or a connecting projection parallel to the engaging groove. A connecting groove that matches the sectional shape of the portion is provided at the other side end of the substrate at a position facing the connecting protrusion.

【Example】

 1 is a front view of the structural unit body, and FIG. 2 is a perspective view of the heat sink.

In the figure, A is a structural unit body, and the structural unit body A is a vertical plate having the same length on the other one surface 1b of the substrate 1 on which the heating element a is mounted on the one surface 1a. 2, and the engaging grooves 3, 3 are provided at a distance from each other and in parallel with each other at equal intervals, and one side end 1c of the substrate 1 is provided with a connecting protrusion 4 and the other side end thereof. The connecting groove 5 is formed in 1d at a position corresponding to the connecting protrusion 4.

Each of the vertical plates 2, 2 ... Is arranged in a direction perpendicular to the substrate 1, and has a cross-sectional shape relatively similar to that of the thickened tip portion 6 of the vertical plate 2. On the other hand, the engaging groove 3 is formed, while the connecting projection 4 and the connecting groove 5 have the same sectional shape relative to each other.

The structural unit A is made of aluminum extruded shape material, and is obtained by cutting the shape material to an appropriate length.

Then, as shown in FIG. 2, a pair of structural units A, A are prepared, and the vertical plates 2, 2 ... When the pair of structural units A, A are assembled by slidingly fitting the tip portions 6, 6 ... Of 2 into the engaging grooves 3, 3, ..., A heat sink as one unit is obtained. A large-sized heat sink can be obtained by connecting the required number of heat sinks to each other at the connecting protrusions 4 and the connecting grooves 6.

Then, the heating element a is attached to the one surface 1a side of the substrate 1, that is, the outer surface of the heat sink, and the fan is installed in the opening for use.

When the engagement groove 3 and the tip portion 6 of the vertical plate 2 are slidably fitted together, or when the coupling projection 4 and the coupling groove 5 are slidably fitted together, the constituent units are fixed to each other by using an adhesive material. be able to.

[0014]

[Effect of device]

 Since the present invention has the configuration as described above, a cylindrical heat sink can be easily obtained by combining a pair of structural units, and a heat dissipation fin (which is impossible even by aluminum extrusion molding). It is possible to reduce the cost of a heat sink with a high density (composed of a vertical plate).
