[Industrial applications]

 The present invention relates to a type of heat radiator, and more particularly, to a type of heat radiator used for a microprocessor.

[0002]

[Prior art]

 The heat generated by the high-speed operation of the microprocessor must be dissipated by a heat dissipation device that has a stable and highly efficient heat dissipation effect. There are known techniques related thereto, such as those described in, for example, Japanese Patent Application Nos. 86206479 and 86209903, which are registered as a utility application in Taiwan.

As shown in FIG. 1, the conventional heat radiating device 5 includes a radiator 7 and a fastening mechanism 6, and the radiator 7 is provided at a plurality of heat radiating plates 71 and a central portion of the radiator 7. It has a fixing portion 72, and the fastening mechanism 6 is used for fixing the radiator 7 above the microprocessor 8. The fastening mechanism 6 includes a fixing tab 61 and a screw 62 for fastening the radiator 7 onto the microprocessor 8; A stop portion 612 is formed, and the lock portion 612 is locked to an edge of the microprocessor 8.

When mounting, the radiator 7 is first installed above the microprocessor 8, and then the fixing tab 61 is mounted on the fixing portion 72 of the radiator 7, and both ends of the fixing tab 61 are pressed to lock the locking portion 612. Then, the screw 62 is screwed into the support hole 613 and brought into contact with the fixing portion 72. As the screw 62 rotates downward, the screw 62 increases the elastic pressure acting on the fixing portion 72, so that the radiator 7 of the heat dissipation device 5 is maintained at a fixed position by the microprocessor 8.

[0005]

However, in the heat dissipation device 5, the radiator 7 is fixed above the microprocessor 8 only by the acting force between the screw 62 and the radiator 7, and between the locking portion 612 and the microprocessor 8. You. When the heat radiating device 5 is vibrated, the radiator 7 is loosened from above the microprocessor 8 and affects the heat radiating effect. Therefore, it is considered that the heat radiating device 5 is not fixed to a fixed position and needs to be further improved.

An object of the present invention is to provide a heat radiating device that can be fixed to a fixed size, so that the heat radiating device can be maintained at a constant level on a microprocessor, and a better heat radiating effect can be achieved.

The fixing base 31 is provided with a fastening plate 312 facing the both sides and a connection plate 311 for connecting the fastening plates 312, and a storage space 310 for housing the heat radiation plate 21 by the fastening plate 312 and the connection plate 311. It is the one that surrounds. The connecting plate 311 extends outward from both ends and bends downward to form a curved portion 314. The curved portion extends rearward by a predetermined distance and is further bent outward to form a protruding portion 315, and a storage groove 3150 is formed in the protruding portion 315. Further, the connection plate 311 has a pressing portion 3110 further extending outward and a fixed groove 3111 installed on the bottom wall at the center (see FIG. 7). At a central portion of the tightening plate 312, a locking portion 316 for locking with the concave tank 24 of the radiator 2 is installed, and further extends outward from both ends of the tightening plate 312 to form a fixed body 317. A convex portion 318 is provided outside the fixed body 317, and a pressing portion 319 for pressing the fixed portion 23 is further provided on the fastening plate 312. Further, the substrate 33 has a fastening portion 331 provided therein.

When the control rod 322 is positioned in the horizontal direction, the protrusion 323 is housed in the fixed groove 3111 to prevent the contact rod 32 from rotating.

As shown in FIGS. 3 and 4, in the assembling process, after the microprocessor 4 is fixed to the printed board 5, the printed board 5 is positioned on the substrate 33, and the fixing section 331 is connected to the corresponding printed board. The control rod 322 is vertically positioned when the base rod 321 is located in the storage portion 22 while being penetrated through the narrow groove 51 of the fifth member 5 and protruding above the printed board 5. Next, the fixing base 31 is attached to the radiator, and after the heat radiation plate 21 is stored in the storage space 310, the locking portion 316 is locked in the concave groove 24 of the radiator 2 so that the fixing base 31 and the fixing base 31 are fixed. When the contact rod 32 is tightened on the radiator 2, the pressing portion 319 presses against the fixing portion 23 of the radiator 2, so that the effect of tightening the radiator 2 and the fixing base 31 is improved. When the radiator 2, the fixed base 31 and the contact rod 32 are moved by a predetermined distance from one side of the board 33 to the left in parallel with the printed board 5, the fixed body 317 is inserted into the recess 332.

You. At this time, the pressing portion 3110 is positioned on the control rod 322 to prevent the control rod 322 from moving upward, and the over-rotation in the downward direction is prevented by the protrusion 315 being positioned below the control portion. Can be prevented. The projections 323 in both radial directions of the base rod 321 abut on the fixing portion 23 of the radiator 2 and the connection plate 311 of the fixing base 31 and are housed in the fixing groove 3111, thereby tightening the radiator 2. The effect can be improved and the rotation of the control rod 322 can be prevented. In addition, the protrusion 323 raises the connection plate 311 so that the fixed body 317 of the fixed base 31 is positioned above the recess 332 of the substrate 33. By the protrusion 318 being locked to the upper edge of the recess 332, the vertical movement of the radiator 2 is limited, and the protrusion 333 is locked to the upper edge of the fixed body 317 on the back side, and the radiator 2 is locked. Limit lateral movement. Therefore, the fixed body 317 of the fixed base 31 and the fastening portion 331 of the substrate 33 are combined to limit the vertical and horizontal movement of the radiator 2. As described above, the radiator 2 is stably fastened on the microprocessor 4, and a good heat radiation effect can be achieved.
