The lamp heat dissipation generally adopts a mode of arranging heat dissipation fins on the shell, and heat exchange is carried out between the heat dissipation fins and outside air so as to accelerate heat dissipation. When it is necessary to improve the heat dissipation effect, the heat dissipation area is generally increased by increasing the number of the heat dissipation fins on the housing, so as to improve the heat exchange rate with the outside air through the heat dissipation fins. However, the conventional heat dissipation fin structure has low heat dissipation efficiency, which is specifically indicated that the utilization rate of the heat dissipation fins is low due to the maximization of the surface area of the heat dissipation fins, for example, the heat dissipation is affected by large heat radiation due to too small space between adjacent heat dissipation fins, or the ventilation effect is poor due to too large height of the heat dissipation fins, thereby causing the problem of non-ideal heat dissipation effect.
Referring to fig. 1 and fig. 2, in order to solve the above technical problems, in a first aspect, the present application provides a heat dissipation structure 100 for dissipating heat of a lamp, where the heat dissipation structure 100 includes a housing 10 and a plurality of long fins 20 disposed on the housing 10, each of the long fins 20 has a first inward end 201, each of the long fins 20 is distributed around a center of the housing 10, each of the first inward ends 201 faces the center of the housing 10, and a distance between adjacent first inward ends 201 is not less than 6 mm. The first inward end 201 refers to an end portion close to the center of the housing 10 when the long fin 20 is disposed on the housing 10; the distance between the adjacent first inward ends 201 is a straight line distance between the end points of the two adjacent first inward ends 201 which are on the same height and closest to the center of the housing 10. It is understood that the first inward ends 201 are the portions of the long fins 20 closest to the center of the housing 10, and each long fin 20 is distributed around the center of the housing 10, i.e., the distance between each adjacent first inward ends 201 is the minimum distance between each adjacent long fins 20.
During the heat dissipation operation, the housing 10 absorbs the heat dissipated during the operation of the lamp, and at the same time, the housing 10 conducts the heat to each long fin 20, and the heat is exchanged with the outside air through the outer surface of each long fin 20 to dissipate the heat efficiently. The first inward ends 201 of the long fins 20 face the inside of the housing 10, and each long fin 20 is distributed around the center of the housing 10, so that a certain distance is formed between each long fin 20 to ensure the heat exchange efficiency between each long fin 20 and the outside air. Meanwhile, the distance between the adjacent first inward ends 201 is set to be not less than 6mm, that is, the minimum distance between the adjacent long fins 20 is controlled to be 6mm, so as to ensure the heat dissipation effect. The above-mentioned manner that each long fin 20 is distributed around the center of the housing 10 may be that the long fins 20 are distributed around the center of the housing 10 evenly, so that each long fin 20 is distributed radially and outwardly at the center of the housing 10, that is, the distance between each adjacent long fins 20 is gradually increased along the direction far from the center of the housing 10, the gap between the long fins 20 at the edge of the housing 10 is larger, the heat exchange effect between the long fins 20 and the outside air is better, and the heat dissipation effect is good. It is understood that the distances from the first inward ends 201 of the long fins 20 to the center of the housing 10 may be the same, different or partially different, and only the distance between the adjacent first inward ends 201 is not less than 6 mm. In the present embodiment, the first inward ends 201 of the long fins 20 are arranged at the same distance from the center of the housing 10, that is, the first inward ends 201 of the long fins 20 are all located on the same concentric circle of the housing 10. By controlling the arrangement of the long fins 20 and the minimum distance between the inward ends of the adjacent long fins 20, the heat dissipation efficiency of the long fins 20 is high, and the heat dissipation effect is better.
Referring to fig. 1 and 2, in one embodiment, the long fin 20 has a first outward end 202 opposite to the first inward end 201, and the first outward end 202 is away from the center of the housing 10 and faces the outside of the housing 10. The first outward end 202 is an end opposite to the first inward end 201 and far from the center of the housing 10 when the long fin 20 is disposed on the housing 10. By arranging the first inward end 201 to face the center of the casing 10 and the first outward end 202 to be away from the center of the casing 10 and face the outside, when the plurality of long fins 20 are arranged on the housing, a channel is formed between the long fins 20, the channel is communicated from the center of the casing 10 to the channel outside the casing 10, and the channel is used for ventilation and heat dissipation, so that the heat in the center of the casing 10 is dissipated outwards. In one embodiment of the present embodiment, the long fins 20 may be heat dissipation fins having a straight plate structure, so that a straight channel from the center of the housing 10 to the outside may be formed to improve the ventilation and heat dissipation effects. In another embodiment of this embodiment, the long fins 20 may be arc-shaped fins, so that the heat dissipation area of the fins is larger and the heat exchange speed is faster.
Referring to fig. 1 and 2, in one embodiment, each of the long fins 20 is a flat plate structure; alternatively, each long fin 20 is an arc-shaped plate structure. When the long fins 20 are of a flat plate structure, the first inward end 201 of the long fin 20 faces the center of the housing 10, and the first outward end 202 of the long fin 20 is far away from the center of the housing 10 and faces the outside of the housing 10, that is, a vertical outward channel is formed on the housing 10 between each two adjacent long fins 20, so as to improve the ventilation capability of the channel, accelerate the air flow rate on the heat dissipation surface of the long fin 20, and further improve the heat exchange rate of the long fins 20 to improve the heat dissipation capability. When the long fins 20 are of an arc-shaped plate structure, the first inward end 201 of the long fins 20 faces the center of the housing 10, and the first outward end 202 of the long fins 20 is far away from the center of the housing 10 and faces the outside of the housing 10, that is, a channel communicated with the center and the outside of the housing 10 is formed between every two adjacent long fins 20 on the housing 10, meanwhile, the long fins 20 are of an arc-shaped structure, the surface area of the long fins 20 is larger, the heat exchanged with the outside air in unit time is more, and the heat dissipation efficiency is effectively improved. It is understood that the arc structure of the long fin 20 may be an arc bent to one side, or may be a wave structure, depending on the actual requirement.
Referring to fig. 1 and 2, in one embodiment, the height of each long fin 20 is 50mm to 65 mm. The height of the long fins 20 is set to be between 50mm and 65mm, so that the long fins 20 have enough height to ensure enough heat dissipation area, and meanwhile, the long fins 20 are not too high to generate larger heat radiation to influence heat dissipation and waste materials.
Referring to fig. 1 and 2, in an embodiment, the heat dissipation structure further includes a plurality of middle fins 30 disposed on the housing 10 and distributed around the center of the housing 10, the length of the long fins 20 is greater than the length of the middle fins 30 along the radial direction of the housing 10, and the middle fins 30 are disposed between adjacent long fins 20. The length of the long fin 20 refers to the length of the intersection of the long fin 20 and the housing 10, and similarly, the length of the middle fin 30 refers to the length of the intersection of the middle fin 30 and the housing 10. By arranging the intermediate fins 30 between the adjacent long fins 20, the heat dissipation area is increased by the intermediate fins 30, thereby accelerating heat dissipation and improving the heat dissipation effect. It is understood that when the housing 10 is large enough, the adjacent middle fins 30 and the long fins 20 have a larger distance therebetween at a position far from the center of the housing 10, and at this time, the middle fins 30 may be further disposed between the adjacent middle fins 30 and the long fins 20; when the two middle fins 30 still have a larger distance from the center of the housing 10, the middle fin 30 may be further disposed between the two middle fins 30; by analogy, the long fins 20 and the sufficient middle fins 30 are arranged on the housing 10 to ensure the heat dissipation efficiency.
Referring to fig. 1 and 2, in one embodiment, the middle fin 30 has a second inward end 301, and a distance between the second inward end 301 and the adjacent long fin 20 or the middle fin 30 is not less than 6 mm. The distance between the middle fin 30 and the adjacent long fin 20 or the middle fin 30 refers to a distance between one of the end points of the second inward end 301 of the middle fin 30 closest to the center of the housing 10 and the adjacent long fin 20 or the middle fin 30, that is, a point-to-surface distance. The middle fin 30 may be understood as being formed by extending the outer edge portion of the housing 10 toward the center of the housing 10, and the distance between the second inward end 301 and the adjacent long fin 20 or the middle fin 30 is gradually reduced as the middle fin 30 extends toward the center of the housing 10. The distance between the second inward end 301 and the adjacent long fin 20 or the intermediate fin 30 is set to be not less than 6mm, so that a sufficient gap is effectively ensured between the intermediate fin 30 and the adjacent long fin 20 or the intermediate fin 30, and the influence of strong heat radiation on the heat dissipation effect due to the over-small distance is avoided.
Referring to fig. 1-3, in one embodiment, at least one long fin 20 is truncated to form a corresponding gap 40; alternatively, at least one of the intermediate fins 30 is truncated to form a corresponding notch 40; alternatively, the at least one long fin 20 and the at least one middle fin 30 are respectively truncated to form the corresponding notches 40. By cutting off the long fins 20 to form the notches 40, the heat radiation surfaces of the long fins 20 and the adjacent long fins 20 or the middle fins 30 are reduced, the heat radiation is effectively reduced, and the heat radiation effect is further improved. Meanwhile, the notches 40 formed by cutting the long fins 20 also increase the ventilation area, i.e., the heat dissipation efficiency. Alternatively, the intermediate fins 30 may be cut to form the corresponding notches 40, or the long fins 20 and the intermediate fins 30 may be cut to form the corresponding notches 40, respectively, to improve the heat dissipation efficiency.
Referring to fig. 1 and 2, in one embodiment, the height of the middle fin 30 is 50mm to 65mm, respectively. The height of the middle fin 30 is set to be 50mm-65mm, so that the middle fin 30 has enough height to ensure enough heat dissipation area, and meanwhile, the middle fin 30 is not too high to generate large heat radiation to affect heat dissipation and waste materials. The height of the middle fins 30 may be set to be the same as or different from the long fins 20, to be different to form a staggered design to improve the gout radiation effect, or to be the same to improve the radiation area.
Referring to fig. 1 to 3, in one embodiment, the long fins 20 and the middle fins 30 are rectangular. The long fins 20 and the middle fins 30 are arranged in the rectangular structures, so that the heat dissipation areas of the long fins 20 and the middle fins 30 are ensured, and the heat dissipation area reduction caused by the arc-shaped structure formed by chamfering is avoided, and further the heat dissipation efficiency is prevented from being influenced.
Specifically, the parameters of the long fins 20 and the middle fins 30 are controlled to compare and test the heat dissipation effect of the heat dissipation structure 100, so as to obtain the parameters with the optimal heat dissipation effect. Specific experimental data are as follows.
Figure BDA0003138933070000091
By analyzing the experimental data, comparing the data of the 1 st group with the data of the 2 nd group, when other conditions are the same, the distance between the adjacent first inward ends 201 is properly widened, the air is more circulated, the heat exchange effect is better, and the heat dissipation effect is better; comparing the data of the 5 th group with the data of the 6 th group, when other conditions are the same, the heights of the long fins 20 and the middle fins 30 are properly increased, the surface areas of the long fins 20 and the middle fins 30 are increased, and the heat dissipation effect is better; comparing the data of the 2 nd group with the data of the 3 rd group, the long fin 20 can be cut off to weaken the heat radiation phenomenon, thereby effectively improving the heat radiation effect; comparing the data of group 3 with the data of group 4, when other conditions are the same, the distance between the adjacent first inward ends 201 is properly widened, and the heights of the long fins 20 and the middle fins 30 are increased, so that the air is more circulated, the surface areas of the long fins 20 and the middle fins 30 are larger, and the heat dissipation effect is better; comparing the data of group 2 with the data of group 5, it can be seen that when other conditions are the same, the distance between the first inward ends 201 is too large, which will obviously reduce the number of the long fins 20, and the heat dissipation effect is worse. Meanwhile, as can be seen from the above experimental data, when the interval between the first inward ends 201 is 7.15mm, the heights of the long fins 20 and the middle fins 30 are 52.5 mm. And the four long fins 20 are cut off to form the notches 40, the heat dissipation effect of the heat dissipation structure 100 is the best, and the operating temperature of the lamp is 75.79 ℃.
In a second aspect, the present application further provides a lamp, which includes a light source and a driver connected to the light source, and further includes the heat dissipation structure 100 as described above, wherein the light source and the driver are mounted on the heat dissipation structure 100. Specifically, the light source is mounted on one side end of the housing 10 of the heat dissipation structure 100 away from the long fins 20, and is drivingly mounted on one side end of the housing 10 where the long fins 20 are disposed. The light source is externally provided with a transparent piece arranged on the shell 10 and is driven to penetrate through the shell 10 to be electrically connected with the light source. On the basis of the heat dissipation structure 100, the lamp provided by the invention has high heat dissipation efficiency and good heat dissipation effect.
