If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0035] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0036] Refer to Figures 1 to 7 , embodiments of the present utility model provide a radiator, which includes a plurality of first fins 120 and a plurality of second fins 130. The first fins 120 and the second fins 130 are fixedly combined together by snap connection and jointly enclose a radially-shaped heat dissipation structure. It is easy to understand that the snap connection structure is simple and convenient for installation, and this snap connection structure also greatly improves the stability of the overall structure. Moreover, the snap connection parts are closely attached, and each connection point supports each other, and can form a stable whole.

[0037] Specifically, the first fins 120 have a plurality of buckles 121, and the plurality of buckles 121 are respectively located at different positions of the first fins 120. The second fins 130 have a plurality of slots 131, and the positions of the buckles 121 and the slots 131 correspond one by one and are snap-connected to each other. It should be noted that the relative position of the first fins 120 fixed to the second fins 130 is determined by the snap connection between the buckles 121 and the slots 131, and the purpose of restricting the movement of the first fins 120 relative to the second fins 130 is achieved.

[0038] Specifically, in some embodiments of the present utility model, such asFigures 2 to 6 As shown, the first fin 120 and the second fin 130 each have an extension portion, which are respectively the first extension portion 125 and the second extension portion 135. The first extension portions 125 are respectively distributed on the upper and lower sides of the first fin 120 and extend in the thickness direction of the first fin 120. For the connection structure between the second extension portion 135 and the second fin 130, reference can be made to the connection structure between the first extension portion 125 and the first fin 120, which will not be described in detail here. A number of first buckles 1211 are provided on the extension portion 125, and the plurality of first buckles 1211 are spaced apart from each other. After the first buckle 1211 extends flatly, it then bends and extends towards the middle of the second fin 130. The second fin 130 is provided with a card slot 131, and the card slot 131 includes a first card slot 1311. The first buckle 1211 corresponds to the first card slot 1311 and abuts against the second extension portion 135 of the second fin 130, thereby restricting the movement of the second fin 130 relative to the first fin 120.

[0039] In some embodiments of the present invention, as Figures 2 to 6 shown, a second buckle 1212 is provided in the middle of the first fin 120. The second buckle 1212 extends towards the side of the second fin 130, and the second buckle 1212 has a stepped convex structure. Its stepped convex structure is used to keep a distance between the first fin 120 and the second fin 130, so as to ensure that there is a space between the end faces of the first fin 120 and the second fin 130. Thus, it can contact the external environment, improving the heat dissipation efficiency of the heat dissipation structure.

[0040] Furthermore, as Figures 2 to 6 shown, the second fin 130 has a limiting card slot 1311. The position of the limiting card slot 1311 corresponds to the position of the second buckle 1212. The second buckle 1212 is located inside the first fin 120 and extends towards the center of the first fin 120. The second buckle 1212 is inserted into the limiting card slot 1311, and the upper and lower sides of the second buckle 1212 respectively abut against the upper wall surface and the lower wall surface of the limiting card slot 1311, thereby restricting the up and down movement of the second fin 130 relative to the first fin 120 in the inner position.

[0041] As Figures 2 to 6As shown, inside the first fin 120 there is a third buckle 1213. The third buckle 1213 has a first alignment inclined surface 12131 which extends towards the center side of the first fin 120. The second fin 130 has an alignment slot 1312. The third buckle 1213 is inserted into the alignment slot 1312. The third buckle 1213 has an abutting plane. When inserted, the first alignment inclined surface 12131 guides the abutting plane to abut against the end face of the second fin 130, thereby restricting the first fin 120 from moving in the direction deviating from the center. And there are two third buckles 1213 and alignment slots 1312, and the two alignment slots 1312 are symmetrically arranged. After the third buckles 1213 are inserted into the alignment slots 1312 one by one, it can restrict the first fin 120 from moving towards the second fin 130. And the first fin 120 can be adjusted along the inclined surface direction. During installation, the first fin 120 can be moved towards the center side for adjustment, which is convenient for installation.

[0042] Furthermore, as Figures 2 to 6 shown, a certain distance is maintained between the first fin 120 and the second fin 130. The existence of the distance enables heat to be more evenly distributed between the first fin 120 and the second fin 130. When heat is transferred from the heat source to the first fin 120 and the second fin 130, the distance helps the heat to spread between the first fin 120 and the second fin 130, avoiding local overheating, thereby improving the heat transfer efficiency of the entire radiator.

[0043] Specifically, there are heat dissipation ring fins 129 on the outer edges of the first fin 120 and the second fin 130 respectively. The heat dissipation ring fins 129 corresponding to the first fin 120 and the second fin 130 are respectively raised and arranged on the end faces of the first fin 120 and the second fin 130. During the operation of the lamp, a large amount of heat can be generated. Based on the large-area heat dissipation ring fins 129 attached to the outer edges, it can better exchange heat with the air flow outside the radiator and can effectively dissipate the working heat of the lamp.

[0044] Specifically, there are heat dissipation ring fins 129 on the outer edges of the first fin 120 and the second fin 130 respectively. The heat dissipation ring fins 129 corresponding to the first fin 120 and the second fin 130 are respectively raised and arranged on the end faces of the first fin 120 and the second fin 130. During the operation of the lamp, a large amount of heat can be generated. Based on the large-area heat dissipation ring fins 129 attached to the outer edges, it can better exchange heat with the air flow outside the radiator and can effectively dissipate the working heat of the lamp.

[0045] Furthermore, as Figures 2 to 6As shown, the heat dissipation ring fins 129 outside the first fin 120 are the first ring fin 122 and the second ring fin 123. The first ring fin 122 and the second ring fin 123 are arranged along the edge direction of the first fin 120 on the first fin 120. The heat dissipation ring fins 129 outside the second fin 130 are the third ring fin 133 and the fourth ring fin 134. The first ring fin 122 is inclined toward the center side of the first fin 120, and the third ring fin 133 is inclined toward the center side of the second fin 130. The first ring fin 122 and the third ring fin 133 have the same inclination angle, and the first ring fin 122 and the third ring fin 133 are alternately arranged to form a hollow structure. The existence of the hollow part enables heat to be transferred from the inside of the radiator to the outside air more quickly. The second ring fin 123 and the fourth ring fin 134 are alternately arranged to form a surrounding structure, increasing the heat dissipation area and improving the heat transfer efficiency.

[0046] Specifically, as Figures 2 to 6 shown, a positioning groove 124 is provided outside the second ring fin 123 of the first fin 120. The opening of the positioning groove 124 is arranged toward the center direction. The second fin 130 is provided with a positioning protrusion 132. The positioning protrusion 132 has a second positioning inclined surface 1321. Among them, the second positioning inclined surface 1321 is inclined toward the positioning groove 124, and the positioning protrusion 132 is inserted into the second positioning inclined surface 1321. It should be noted that the first positioning inclined surface 12131 enables the first fin 120 to move and adjust toward the center direction, and the second positioning inclined surface 1321 enables the first fin 120 to adjust along a direction deviating from the center. In some embodiments, the inclination directions of the second positioning inclined surface 1321 and the first positioning inclined surface 12131 are opposite, which has the effect of mutually restricting movement, thereby restricting the movement of the first fin 120 relative to the second fin 130 in the horizontal direction, aligning the first fin 120 and the second fin 130 in the center, and making the structure firm and convenient for installation.

[0047] Specifically, the first fin 120 is provided with ventilation holes, and the second fin 130 is also provided with ventilation holes at the same positions. Taking the first fin 120 as an example, the ventilation holes are divided into a first ventilation hole 126 and a second ventilation hole 127. The first fin 120 includes an integrally connected body 128 and an extension part 125. The extension part 125 is arranged at the bottom of the body 128 and extends in the thickness direction of the body 128. The first ventilation hole 126 is penetrated through the body 128 to communicate with the adjacent second fin 130, and the second ventilation hole 127 is penetrated through the extension part 125 to communicate the inside and the outside of the first fin 120. These ventilation holes can allow air to form better convection inside the radiator, transfer the heat transmitted from the lamp cover or other external connectors, thereby improving the heat dissipation efficiency.

[0048] Specifically, as Figure 7As shown in the figure, the radiator further includes an auxiliary ring 140. When the first fins 120 and the second fins 130 are installed, they can be inserted into the auxiliary ring 140 one by one, and a plurality of first fins 120 and a plurality of second fins 130 are enclosed together. Optionally, there are several clamping grooves 141 on the periphery of the auxiliary ring 140. The first fins 120 are inserted into the clamping grooves 141 to fix a part of them thereon. The auxiliary ring 140 can provide positioning for the radial installation of a plurality of first fins 120 and a plurality of second fins 130, facilitating the installation.

[0049] It should be noted that the structures of the first fins 120 and the second fins 130 are similar, or the structures of the first fins 120 and the second fins 130 are exactly the same. It is easy to understand that the connection structure between the second fin 130 and the next adjacent first fin 120 can refer to the connection structure between the previous first fin 120 and this second fin 130, and will not be described in detail here.

[0050] In summary, the above radiator has a simple structure and is convenient to install. The connection method between the fins of the radiator through the buckle 121 not only shows excellent stability. In the traditional connection method, welding or screw connection requires a lot of time for fine operation, and professional tools and technicians are required to ensure the connection quality, which undoubtedly increases the production cost and time cost. The first fins 120 and the second fins 130 are installed by snap-fit, which greatly facilitates the assembly of the first fins 120 and the second fins 130 and improves the structural stability.

[0051] The present utility model proposes a lamp, including the above radiator. The radiator has the characteristics of being convenient to assemble. The lamp also utilizes the excellent heat dissipation performance of the radiator to improve the service life and stability of the lamp.

[0052] By optimizing the structure of the radiator and increasing the heat dissipation area of the first fins 120 and the second fins 130, the heat dissipation performance of the lamp is significantly improved, which enables the light-emitting element to work at a relatively low temperature. The lower working temperature not only prolongs the service life of the light-emitting element, but also reduces the light decay phenomenon caused by high temperature, so that the bulb lamp can maintain a stable brightness and good lighting effect during long-term use.

[0053] In addition, the above radiator and lamp provided by the embodiments of the present utility model have been introduced in detail. In this article, specific examples have been used to elaborate the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
