Each of the heat dissipating vanes 11 is provided with a lower bending piece 12 bent in one direction at a lower end thereof,

Each of the lower bending pieces 12 is provided with a lower engaging projection 12a extending from one end and a lower engaging groove 12b formed in the other bending portion.

Here, the lower bent piece 12 is bent in one direction is formed not only in the form in which the upper surface of the flat base plate 21 is bent, but also in the case where the adhesive application surface 23 of the base plate is inclined at a predetermined angle It means that the upper bending piece 14 is bent at an angle corresponding thereto, and the upper bending piece 14 to be described later also has to be interpreted in the same sense.

The lower bending piece 12 is formed so as to have intensified external light that widens from left to right in the lateral direction in consideration of the angle at which the heat radiating blades 11 are radially arranged, The same can be applied to the upper bending pieces 14 described later.

The lower engaging protrusions 12a and the lower engaging recesses 12b of the lower bending pieces 12 are engaged with the adjacent heat dissipating wings 15a and 15b as in the inner engaging protrusions 15a and the inner engaging recesses 15b of the inner bending piece 15, 11 to each other to function as coupling means for allowing the heat radiating vanes 11 to be arranged radially spaced apart at a predetermined distance.

The lower engaging protrusion 12a and the lower engaging groove 12b and the upper engaging protrusion 14a and the upper engaging groove 14b to be described later are provided with a fastening protrusion (not shown) There is a difference.

First, the adhesives for steps A) and C) are steel adhesives having good heat resistance and corrosion resistance. In step A), the adhesive is applied to the base plate 21 in a ring shape .

The method of applying the adhesive in the step A) is the same as the method of applying the adhesive to the base plate 21 at the center of the bottom surface of the receiving groove 121 An application plate 120 including a sealing part 122 corresponding to a non-application area and a screen part 123 formed along an outer periphery of the sealing part 122; And a plunger 139 for allowing the adhesive to be applied to the adhesive-coated surface 23 of the base plate 21 by passing the adhesive through the screen portion 123 can be used.

A through hole 122a is formed at the center of the sealing part 122 so that the support member 25 of the mounting member 20 is inserted into the through hole 122a, The adhesive is not applied to the central portion of the base plate 21, that is, the portion overlapping with the sealing portion 122, and the adhesive agent is not applied to the base portion 21, An adhesive is applied only to the outer circumferential portion of the plate 21, that is, the portion overlapping with the screen portion 123, and the application plate 120 and the mounting member 20 are separated from each other, The adhesive application surface is formed only in a predetermined area.

When the mounting member 20 and the heat dissipating member 10 are coupled while the support rod 25 of the mounting member 20 is inserted into the hollow portion 16 of the heat dissipating member 10 in the step B) 21 are attached and fixed to the lower attachment surface 18 of the heat dissipating member 10, that is, the surface portions connected to the lower bending pieces 12.

Then, in step C), the adhesive is applied to one surface (the lower surface in the figure) of the stationary ring 30.

The adhesive applied to the stationary ring 30 in step C) is preferably a general nozzle coating method other than the screen coating method as in step A).

When the fixing ring 30 is fitted into the fitting groove 13 formed by the first cutout 13A and the second cutout 13B of the heat dissipating member 10 in the step D) ), That is, the upper bending piece 14 is formed in the first cutout portion 13A.

Therefore, in step C), after the adhesive is applied to a part of one side of the fixing ring 30, the adhesive application surface of the fixing ring 30 is inserted into the fitting groove 13 of the heat dissipating member 10, The fixing process of the mounting member 20 and the heat dissipating member 10 is completed.

In this case, when the cap member 29 using the bonding adhesive method is introduced, an adhesive is applied to the step portion 25a of the support member 25, and then the cap member 29 is fitted on the support member 25, 29 and the mounting member 20 can be engaged with each other.

Also in the adhesive application operation of the support rod 25, since the width of the step portion 25a is narrow, an adhesive application method using a general nozzle is preferable.

The application and attachment of the adhesive for the bonding bonding of the cap member 29 and the mounting member 20 may be performed before or after any of the steps A) to D), but before the step B) It is more preferable that the cap member 29 is applied before and after any of the steps B) to D) after the adhesive is applied to the step portion 25a of the step 25,

In the manufacturing method according to the present invention, the steps A) and B) and the steps C) and D) may be different from each other.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And substitutions are to be construed as falling within the scope of protection of the present invention.
