Detailed Description
Referring to fig. 1 to 3, the present invention is a lamp radiator, comprising a radiator body 1 and a fan 2, wherein the radiator body 1 comprises a base 11 and two fin groups 12, the bottom of the fin group 12 is connected with the top of the base 11, and the fan 2 is located between the two fin groups 12. When the lamp is used, the base 11 is in contact with a heat source, heat generated when the lamp generates heat is conducted to the radiating fin group 12 through the base 11, and air flow generated when the fan 2 rotates passes through the radiating fin group 12, so that the heat on the radiating fin group 12 is rapidly emitted into the air.
Through the structure, the radiator main body 1 can utilize the air flows at two sides of the fan 2, and the fan 2 can make the air flow pass through the radiating fin group 12 only by blowing the air for a short distance, thereby being beneficial to rapidly blowing heat, achieving the purpose of rapid cooling, and reducing the power and the load of the fan 2. In addition, the fan 2 is located between the two fin groups 12, so that the distance between the radiator body 1 and the mounting surface can be reduced, the mounting space of the radiator body 1 is reduced, the mounting arrangement of the invention is facilitated, and the back pressure of the fan 2 can be prevented from being increased due to the fact that the distance between the radiator body 1 and the mounting surface is too small.
Specifically, the fin group 12 includes a plurality of fins, and the fins of the two fin groups 12 are disposed opposite to each other, which is beneficial to air flow and reduces air flow resistance.
Two locating sheet seats 3 are arranged on the base 11, a space is reserved between the two locating sheet seats 3, a clamping groove 31 matched with the fan 2 is formed in the locating sheet seats 3, and the side part of the fan 2 is clamped in the clamping groove 31 so as to facilitate the disassembly and assembly of the fan 2. The locating plate seat 3 is sheet-shaped, heat on the base 11 can be conducted to the locating plate seat 3, and then the heat is emitted to the outside through the locating plate seat 3, so that the heat dissipation effect of the invention is improved. In addition, the fan 2 may be connected to the base 11 or the spacer 3 by means of screw locking.
The space is arranged between the two locating plate seats 3, so that an air duct 5 is formed between the two locating plate seats 3, the fan 2 is positioned in the air duct 5, and air flow generated during rotation of the fan 2 is concentrated, so that the working efficiency of the fan 2 is improved.
The spacer 3 and the heat sink 12 have a space therebetween such that the ventilation channel 4 is formed between the spacer 3 and the heat sink 12. When the fan 2 rotates, air flows through gaps between the fins into the ventilation flow passage 4, then through the fan 2, and through the fan 2 into the other ventilation flow passage 4, and finally through the other fin group 12. The ventilation flow passage 4 can reduce the resistance of air flow, so that more air flows through the radiating fins far away from the fan 2, and the radiating effect is optimized. In addition, the air flow contacts with the side wall of the locating piece seat 3 when passing through the ventilation flow channel 4, and takes away the heat on the locating piece seat 3.
Further, the spacer seat 3 has a flange 32, and the flange 32 is located at the end of the ventilation channel 4. The folds 32 are able to change the direction of the air flow, prevent the air flow from passing directly through the ends of the ventilation channels 4, force the air flow to pass through the gaps between the cooling fins and take away the heat on the cooling fins, so as to improve the cooling efficiency.
In the invention, the radiating fin group 12 and the base 11 are of an integrated structure, so that the thermal resistance between the radiating fin group 12 and the base 11 can be reduced, and the heat conduction efficiency can be improved. Similarly, the spacer seat 3 and the base 11 may be integrally formed. Of course, the fin group 12 and the fin base 3 may also be embedded on the base 11.
The invention also comprises a top cover 6, wherein the top cover 6 is connected to the radiator main body 1 and shields the upper end face of the radiator main body 1, namely, the top cover 6 shields the upper end openings of the air duct 5 and the ventilation flow channel 4 at the same time and shields the upper end face of the radiating fin group 12. The top cover 6 can limit the air flow direction, so that more air flows pass through the radiating fin group 12 and fully contact with the side walls of the radiating fins to take away more heat, and the radiating efficiency is further improved. When the radiator is installed and used, the top of the radiator main body 1 can be close to or clung to the installation surface, so that the installation space required by the radiator main body 1 is further reduced, and the radiator can efficiently radiate heat even in a narrow installation space. In addition, the top cover 6 contacts the fan 2 to restrict the fan 2 from sliding out of the clamping groove 31.
The above examples are only preferred embodiments of the application, and other embodiments of the application are possible. Equivalent modifications and substitutions can be made by those skilled in the art without departing from the spirit of the application, and these equivalent modifications or substitutions are intended to be included within the scope of the present application as set forth in the following claims.
