The present invention relates to a support heat dissipation device, and more particularly, to a support heat dissipation device using a pressing member having a cam cross section for supporting and dissipating an electronic device.

In general, an electronic device, such as a radio repeater that emits radio waves or relays radio waves, generates a lot of heat because a plurality of components are integrated inside the electronic device.

Heat generated from the electronic device should be discharged to the outside through a predetermined cooling device, etc. If the heat inside the electronic device is not properly released, the temperature of the electronic device itself will rise, causing the electronic device to fail or malfunction to the electronic device. This happens.

As shown in FIG. 2, the crimping member 300 is rotatably supported by the support hole 211 of the support main body 210 and is located in the space S.

The crimping member 300 includes a first end 300a and a second end (not shown) rotatably supported by the support body 210, and between the first end 300a and the second end (not shown). A cam shaft portion 300b including a cam cross section is provided. The cam shaft portion 300b has a rod shape and has a cam cross section having a long axis P. As shown in FIG.

The first end 300a of the crimping member 300 protrudes through the support hole 211, and the rotating ring 500 which is coupled to the first end 300a by the first end 300a protrudes. Are combined.

The elastic member 400 is positioned between the crimping member 300 and the iron portion 210a of the support body 210, and the elastic member 400 is pressed against the elastic member 400 when pressed by the elastic member 400. The cam cross section is formed in a plane.

The elastic member 400 includes a push pin 410, a stop ring 420 and a compression spring 430.

The pressing pin 410 facing the pressing member 300 is in surface contact with the pressing member 300, and the stop ring 420 fixes the pressing pin 410 to the support body 210. One side of the compression spring 430 is supported by the convex portion 210a of the support body 210 to apply pressure in the direction of the pressing member 300 so that the pressing pin 410 fixes the pressing member 300.

The elastic member 400 is elastic by the compression spring 430, and applies pressure in the direction of the pressing member 300 in a state supported by the convex portion 210a of the support body 210.

The elastic member 400 and the crimping member 300 are in surface contact.

The rotary ring 500 is in shape coupling with the first end 300a of the crimping member 300.

In this way, the cam cross section can be driven by transmitting a rotational force to the cam shaft part 300b by the operation of the rotary ring 500.

An operation of mounting the electronic device 5 to the supporting heat dissipation device 1 configured as described above will be described with reference to FIGS. 3 and 4.

3 is a view in which the cam shaft part 300b is rotated after the electronic device 5 is inserted into the supporting heat dissipation device 1 according to the exemplary embodiment of FIG. 2, and FIG. 4 is IV-IV of FIG. 3. A cross section along the.

First, as shown in FIG. 3, the electronic device 5 is inserted into a space S formed by the heat sink 100 and the support cover 200.

Holding the device handle 52 of the electronic device 5, the electronic device 5 is inserted into the separation space S through the guide rail 230 corresponding to the guide protrusion 51 of the electronic device 5.

At this time, since the width of the guide rail 230 is larger than the width of the guide protrusion 51, the width of the guide rail 230 is supported by the electronic device 5 without interference between the electronic device 5 and the supporting heat dissipation device 1. It is inserted into the space (S) of the heat dissipation device (1).

Next, the cam shaft part 300b of the crimping member 300 is rotated through the rotation ring 500 while the electronic device 5 is inserted.

Rotating the rotary ring 500, which is coupled to the first end 300a of the crimping member 300, causes the first end 300a supported by the support hole 221 to rotate. As a result, the cam shaft 300b of the crimping member 300 rotates, and the long axis P of the crimping member 300 faces the electronic device 5. That is, the pressing member 300 compresses the electronic device 5 in the direction of the heat sink 100.

As shown in FIG. 4, when the long axis P of the crimping member 300 faces the electronic device 5, the electronic device 5 moves in the direction of the heat sink 100 by one height h so that the heat sink ( 100). At this time, the elastic member 400 makes a surface contact with the crimping member 300 to apply pressure in the direction of the electronic device 5. As a result, the elastic member 400 fixes the crimping member 300. As the crimping member 300 is fixed, the electronic device 5 is fixed to the heat sink 100 to make surface contact with the heat sink 100.

In this way, the electronic device 5 is firmly fastened to the supporting heat dissipation device 1.

When the electronic device 5 is separated from the support heat dissipation device 1, the compression member 300 is rotated through the rotation ring 500 to relax the electronic device 5 from the heat sink 100, and then in the reverse order of the above-described order. The electronic device 5 is easily detached from the supporting heat dissipation device 1 when performed.

On the other hand, when the electronic device 5 having a thick thickness t is inserted into the space S of the supporting heat dissipation device 1, when the pressing member 300 is rotated through the rotation ring 500, the supporting body part is supported. Since the support hole 211 of the 210 is formed in an elliptical shape extending vertically, the first end 300a and the second end (not shown) of the crimping member 300 are connected to the ellipse of the support hole 211. Guided to move upward. In other words, it moves in the upward direction over the entire cam shaft portion 300b.

Since the cam shaft portion 300b is moved upward, the pressing pin 410 of the elastic member 400 is also moved upward, and the stop ring 420 is pressed to fix the pressing pin 410. Fasten to the pin 410.

As described above, since the support hole 211 is formed in an elliptical shape, even if the electronic device 5 having a different thickness t is inserted into the separation space S, the height of the crimping member 300 supporting the electronic device 5 is increased. Since the heat treatment is controlled, the support heat dissipation device 1 according to an embodiment of the present invention can be used for the electronic devices 5 having different thicknesses.

As a result, a supporting heat dissipation device having improved efficiency of fastening and detachment with respect to the electronic device 5 is provided.

Hereinafter, the heat dissipation effect of the supporting heat dissipation device 1 with respect to the electronic device 5 will be described with reference to FIG. 4.

Since the electronic device 5 is in close contact with the second surface 100b of the heat sink 100 due to the elastic member 400 and the pressing member 300, the electronic device 5 has a large contact area. Therefore, heat generated in the electronic device 5 quickly moves to the heat sink 100 through the large contact area.

Heat moved to the heat sink 100 is radiated to the outside of the heat sink 100 through the heat radiation member 110 of the heat sink 100 is formed in the concave-convex shape to increase the surface area.

Heat radiated to the outside of the heat sink 100 is exchanged with cold air of the heat sink 100.

As described above, heat generated in the electronic device 5 is rapidly radiated through the heat sink 100.

Thereby, the support heat radiation device 1 with which the heat radiation efficiency with respect to the electronic device 5 was improved is provided.
