Abstract
The utility model relates to a heat-radiating fixing clamp which is an electric element in a U-shaped structure and is used for fixing a heat-emitting electron device and a heat-transmitting or heat-radiating fin. The heat-emitting electron device is fixed on the heat-radiating fin through clamping arms at two sides. After the scheme is adopted, mounting holes as well as screws and nuts need not be punched on the heat-emitting electron device and the heat-radiating fin, therefore, the problem of counterpoint between the mounting hole of the heat-radiating fin and the mounting hole of the heat-emitting electron device is solved; and after products are upgraded, the heat-emitting electron device is also tightly arranged on the heat-radiating fin if shifting.
Description
Technical field
The utility model belongs to the heat radiation field of electronic device, relates to a kind of heat radiation geometrical clamp specifically, and fixing between electronic device and the biography/fin is used to generate heat.
Background technology
Present electronic device all is to adopt the screw electronic device (triode that encapsulates such as TO220) that will generate heat to be locked on the installing hole of fin at the fixing means on the fin, and its shortcoming mainly contains:
1, after model change, displacement has taken place in the position of the heater members on the circuit board, and the installing hole on the electronic device can't align with the installing hole on the fin, and the fin before making is scrapped, if fin and shell are one, whole casing is scrapped;
2, owing to adopt screw that electronic device is locked on the fin, this just need stamp installing hole on electronic device and fin, and trouble is installed.
Summary of the invention
For overcoming above-mentioned defective, main purpose of the present utility model is to provide a kind of heat radiation geometrical clamp, the heating electronic device closely can be clipped on the fin, and quick for installation, easy to adjust.
In order to reach above-mentioned purpose, solution of the present utility model is: a kind of heat radiation geometrical clamp, and it is an elastic component, is " U " font structure, the electronic device that will generate heat of the clamping limb by both sides is fixed on the fin.
The material employing of heat radiation geometrical clamp has Memorability and flexible material forms.
Further improvement of the utility model is:
For guaranteeing that after temperature rises the heat radiation geometrical clamp can also keep stronger elasticity, is provided with some strengthening grooves at the top curved place.
In order to improve radiating effect, fixedly connected auxiliary heat dissipation sheet on a clamping limb of heat radiation geometrical clamp, and auxiliary heat dissipation sheet two ends further can being improved: be die-cut into the pinniform structure that staggers.The space can be adopted Heat Conduction Material to do and fill and be improved thermal conductivity between while auxiliary heat dissipation sheet and the clamping limb.
For make the heat radiation geometrical clamp can on the heatsink transverse sheet, arbitrarily move installation, can on a clamping limb, have mounting groove, and not with the auxiliary heat dissipation sheet on same clamping limb.
The easiness of installing for the geometrical clamp that guarantees to dispel the heat can be further flips to the outside, is bent into hook formation with the clamping limb end of both sides.
Description of drawings
Fig. 1 is the three-dimensional structure diagram of heat radiation geometrical clamp;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is that the B of Fig. 1 is to view;
Fig. 4 is user mode figure of the present utility model.
Wherein: 1. strengthening groove, 2. clamping limb, 3. pad, 4. auxiliary heat dissipation sheet, 5. hook-shaped bending section, 6. mounting groove, 7. heating electronic device.
Embodiment
To closing the drawings and specific embodiments the utility model is further described below.
To shown in Figure 3, the utility model adopts the elastomeric material with Memorability to make formation, as iron-based alloy, and is " U " structure referring to accompanying drawing 1, and the electronic device 7 that will generate heat of the clamping limb 2 by both sides closely is fixed on the fin; Top curved place at the heat radiation geometrical clamp adds corrugated strengthening groove 1, can strengthen the elastic force of geometrical clamp like this, and after temperature raise, can continue guarantees to dispel the heat fixedly accompanied enough elastic force; Insert at the heat radiation geometrical clamp on the clamping limb 2 of fin inboard and increase mounting groove 6, so not only convenient heat radiation geometrical clamp can insert fin, can also make the heat radiation geometrical clamp in position that the fin up conversion is inserted; Increase on another clamping limb 2 that auxiliary heat dissipation sheet 4 is welded to the heat radiation geometrical clamp, pad is unrestricted, can be 4 points, etc. at 3, and its position is also unrestricted.The heat energy on the heat radiation geometrical clamp is added with Heat Conduction Material in the slit between auxiliary heat dissipation sheet 4 and the heat radiation geometrical clamp and does filling, so that can successfully be delivered on the auxiliary heat dissipation sheet 4.
The utility model adds man-hour, section strikes out corrugated strengthening groove 1 therebetween earlier, offer mounting groove 6 on one side, then it is bent to " U " shape and structure described in the accompanying drawing 1, the outside of an end at the Hair Fixer hot-electron device 7 of heat radiation geometrical clamp, auxiliary heat dissipation sheet 4 in the welding adds silicone grease between auxiliary heat dissipation sheet 4 and the heat radiation geometrical clamp and does filling, and hook-shaped bending section 5 at last flips to the outside at two ends.As shown in Figure 4: the utility model can be coated Heat Conduction Materials such as silicone grease in the both sides of the inboard of heat radiation geometrical clamp and heating electronic device 7 when in use, utilizes clamping limb 2 will generate heat electronic device 7 crampings to fin then.
After adopting such scheme, electronic heating element 7 does not need to beat installing hole with fin, does not need screw and nut certainly yet, has so not only solved the contraposition problem of installing hole with the installing hole of heating electronic device 7 of fin; And after model change, if heating electronic device 7 displacement problems, heating electronic device 7 still can closely be installed on the fin.
