[0002] Generally, a radiator for an LED lamp basically consists of a main heat dissipation plate and a plurality of heat dissipation fins. Although the heat dissipation area can be increased, the ventilation design is usually not considered, so that the effect of heat convection is not significant.

[0003] In addition, in order to increase the heat dissipation area, as well as reduce the weight and cost, it is usually necessary to process thinner and more heat dissipation fins. However, due to the thinning of the thickness of the heat dissipation fins, the fin strength is poor, and deformation and breakage are likely to occur. Summary of the Utility Model

The plurality of enclosing sections can be sequentially arranged on the peripheries of multiple groups of two adjacent heat dissipation fins arranged at intervals.

[0009] For a radiator as described above, the connection section is connected between the sides of adjacent mounting sections away from the enclosing section, and connection sections are arranged between the upper and lower sides of adjacent mounting sections. A heat dissipation window is formed between the two connection sections.

[0010] A radiator as described above, the distance between two adjacent heat dissipation fins gradually increases from the center of the bottom plate to the circumferential side, and the distance between the two mounting sections gradually decreases from the connection with the surrounding section to the center of the bottom plate.

Detailed implementation manners

[0025] As Figures 1-5 shown, a radiator includes a bottom plate 1 and a plurality of heat dissipation fins 2 arranged in an annular array on the bottom plate 1. It further includes a flow guide member 3 connected between two adjacent heat dissipation fins 2. A convection chamber 4 is formed between the flow guide member 3 and the two heat dissipation fins 2 it is connected to. Convection holes 10 communicating with the convection chamber 4 are formed on the bottom plate 1. By providing the flow guide member 3 in the present application, a convection chamber 4 can be formed between the flow guide member 3 and the heat dissipation fins 2, and convection holes 10 are formed on the bottom plate 1. A convection channel can be formed between the convection holes 10 and the convection chamber 4, improving the effect of heat convection and enhancing the heat dissipation capacity. Moreover, the flow guide member 3 is connected between two adjacent heat dissipation fins 2, which can improve the structural strength.

[0026] Furthermore, as Figure 1 shown, in a specific embodiment of the present application, the flow guide member 3 is arranged on the peripheries of two adjacent heat dissipation fins 2, so that a vertically hollow convection chamber 4 is enclosed between the flow guide member 3 and the two adjacent heat dissipation fins 2. Through this design, a convection channel can be formed, improving the effect of heat convection and enhancing the heat dissipation capacity.

[0027] Even further, as Figure 4 shown, in a specific embodiment of the present application, the flow guide member 3 includes an enclosing section 31 arranged between the peripheries of two adjacent heat dissipation fins 2 and mounting sections 32 arranged on both sides of the enclosing section 31 and extending towards the center of the bottom plate 1. The two mounting sections 32 are respectively attached to the sides of two adjacent heat dissipation fins 2 away from each other. During assembly and use, the mounting sections 32 on both sides of the enclosing section 31 are respectively attached to the sides of the two heat dissipation fins 2, and the enclosing section 31 encloses between the two heat dissipation fins 2, so that a vertically hollow convection chamber 4 is formed between the enclosing section 31 and the two heat dissipation fins 2. A convection channel can be formed between the convection holes and the convection chamber, improving the effect of heat convection and enhancing the heat dissipation capacity. Moreover, the mounting sections 32 on both sides are connected between two adjacent heat dissipation fins 2, which can improve the structural strength.

[0028] Still further, as Figure 4As shown, in the specific implementation manner of the present application, a plurality of the surrounding segments 31 are provided on the flow guide member 3 at intervals, and the plurality of the surrounding segments 31 are connected into one body through the connecting segments 33. The plurality of the surrounding segments 31 can be sequentially arranged on the peripheries of multiple groups of adjacent two heat dissipation fins 2 arranged at intervals. A plurality of the surrounding segments 31 are provided on the flow guide member 3 of the present application and can respectively surround the peripheries of multiple groups of adjacent two heat dissipation fins 2 to form a plurality of convection chambers, and convection holes corresponding to and communicating with each convection chamber are formed in the bottom plate.

[0029] As a further limitation, the connecting segment 33 is connected between the adjacent mounting segments 32 on the side away from the surrounding segment 31, and the connecting segments 33 are provided between the upper and lower sides of the adjacent mounting segments 32. A heat dissipation window 30 is formed between the two connecting segments 33. The surrounding segment 31, the mounting segment 32 and the connecting segment 33 of the present application are integrally formed, which is convenient for production and assembly, and the heat dissipation window 30 can further improve the effect of heat convection and enhance the heat dissipation capacity.

[0030] Further, as Figure 2 and 3 shown, the distance between two adjacent heat dissipation fins 2 gradually increases from the center of the bottom plate 1 to the circumferential direction, and the distance between the two mounting segments 32 gradually decreases from the connection part with the surrounding segment 31 to the center of the bottom plate 1. This design can form a snap-fit assembly effect, which is convenient for assembly and improves the assembly stability effect, and avoids deformation of the heat dissipation fins 2.

[0031] Still further, in the specific implementation manner of the present application, a plurality of the flow guide members 3 are provided on the radiator, and a detachable structure 34 for detachable connection is provided between the plurality of the flow guide members 3. More specifically, the plurality of the flow guide members 3 are connected to each other and surround the periphery of the heat dissipation fins 2. By providing a plurality of mutually detachable flow guide members, an annular flow guide and stabilizing structure can be formed on the periphery of the radiator, which can enhance the heat dissipation capacity and improve the structural strength. Specifically, as Figure 3 and 4 shown, the detachable structure 34 is a cooperation of a card slot and a protrusion, which is convenient for assembly and improves the stable connection effect between the flow guide members.

[0032] Further, as Figure 5 shown, communication holes 20 connecting the convection chambers 4 are formed in the heat dissipation fins 2. This design can further improve the effect of heat convection and enhance the heat dissipation capacity.

[0033] The present application also provides a lighting fixture, as Figure 6As shown, it includes a radiator as described above. When in use, the lamp shade is installed on the bottom plate, and the light source is arranged closely against the bottom plate, so that the heat source can be timely conducted through the bottom plate to the heat dissipation fins for heat dissipation. By providing convection holes on the bottom plate, the convection chamber can be communicated with the inside of the lamp shade to form a convection channel, improving the effect of heat convection and enhancing the heat dissipation capacity.
