[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to the attached Figures 1-5 description, the present utility model provides a high-power radiator for a spotlight, which is installed on a spotlight for use, including a copper base 1. Aluminum bases 2 are fixedly welded on both sides of the copper base 1. A plurality of aluminum fins 3 are fixedly welded on the tops of the copper base 1 and the two aluminum bases 2. Specifically, the number of aluminum fins 3 is 60. The plurality of aluminum fins 3 are linearly arrayed on the tops of the copper base 1 and the two aluminum bases 2 to improve the heat dissipation effect. A plurality of heat pipes 4 are fixedly arranged among the plurality of aluminum fins 3. Specifically, the number of heat pipes 4 is 26, and the heat pipes 4 are 10 mm thick. A plurality of fixing holes 10 are formed in each aluminum fin 3, and the plurality of heat pipes 4 respectively penetrate through the plurality of fixing holes 10 to improve the stability between the heat pipes 4 and the aluminum fins 3;

[0025] Both sides of the copper base 1 are provided with slots 5. On one side of each of the two aluminum bases 2 close to the copper base 1, there are fixed insertion blocks 6 inserted into the slots 5. In front of multiple aluminum fins 3, there are two intake fans 7 on each side, and behind multiple aluminum fins 3, there are two exhaust fans 8 on each side, which are used to accelerate the heat dissipation speed of multiple aluminum fins 3. On both the front and rear sides of multiple aluminum fins 3, there are fixed components 9 for installing two intake fans 7 and two exhaust fans 8.

[0026] Among them, the two intake fans 7 and the two exhaust fans 8 both adopt NF-F123 low-noise, high-air volume and high-air pressure 12025 fans, with a rotation speed of 2000 RPM, a noise of 29.7 dBA, a static pressure of 3.94 mmH2O, and an air volume of 121.8 M3 / H, which can both accelerate heat dissipation and meet the low-noise requirement.

[0027] Moreover, a thermal grease layer 11 is applied to the bottom end of the copper base 1, and a release film 12 is fixedly adhered to the bottom end of the copper base 1. The release film 12 is arranged outside the thermal grease layer 11 to protect the thermal grease layer 11 from being contaminated by the release film 12.

The two intake fans 7 can be detachably fixed on the frame 901 in front of the aluminum fins 3, and the two exhaust fans 8 can be detachably fixed on the frame 901 behind the aluminum fins 3, which is convenient for the staff to quickly install the intake fans 7 and the exhaust fans 8.

[0030] Moreover, on each fixing plate 902, there are two positioning rods 903 fixed. On the outermost aluminum fins 3 of the two aluminum bases 2, there are two positioning slots 904 opened. The positioning rods 903 are inserted into the positioning slots 904, and the cooperation between the positioning rods 903 and the positioning slots 904 is used to facilitate the staff to quickly install the fixing plates 902.

[0031] Two intake fans 7 and two exhaust fans 8 are respectively supported by two frames 901. The staff can remove the intake fans 7 and the exhaust fans 8 by disassembling the frames 901 for cleaning and replacement. The structure is simple and very convenient to use. Moreover, by using the cooperation of the positioning rods 903 on the fixing plate 902 and the positioning grooves 904, it is convenient for the staff to quickly install the frames 901.

[0032] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
