Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is further illustrated, and the content that embodiment is mentioned not is limitation of the invention.See Fig. 1 to Fig. 5, below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1 to Figure 3, a kind of high-efficiency radiator provided by the present invention, comprise heat dissipation base 1, the center of described heat dissipation base 1 gives off some equally distributed radiating fins to surrounding, described radiating fin includes the first radiating fin 2 and the second radiating fin 3, is provided with second radiating fin 3 between every two adjacent the first radiating fins 2; The apical side height of described first radiating fin 2 and the second radiating fin 3 all has height change, the top of described first radiating fin 2 forms the first fin trough 21 by high step-down gradually from the center of heat dissipation base 1, then uprises step-down gradually from the first fin trough 21 again and forms the first fin crest 22; The top of described second radiating fin 3 forms the second fin trough 31 from the center of heat dissipation base 1 by high step-down, then uprises step-down gradually from the second fin trough 31 again and forms the second fin crest 32,
First radiating fin 2 of high-efficiency radiator of the present invention and the apical side height of the second radiating fin 3 all have height change, therefore irregular air-flow can be formed, the height of the heat sink of traditional heat sinks or radian change all consistent, make traditional heat sinks can only the radiating airflow of generation rule, the temperature difference is there is between fin trough of the present invention and fin crest, because air all flows to low-temperature region by high-temperature area, therefore top of the present invention easily forms propelling movement air-flow.As shown in Figure 2, when this high-efficiency radiator is in dynamic air current, the temperature of the first fin trough 21 and the temperature of the second fin trough 31 are all high than the temperature of the first fin crest 22, second fin crest 32, form the first radiating airflow ring and the second radiating airflow ring of rising above the first fin trough 21, second fin trough 31 respectively.Because light fixture heat gathers toward center, the central temperature of described heat dissipation base 1 is higher; Under dynamic air current condition, the heat radiation around heat dissipation base 1 is comparatively large, and the heat radiation that can form one rule pushes air-flow; In like manner, higher than the temperature of the first fin crest 22, second fin crest 32 at the heat at the first fin trough 21 and the second fin trough 31 place, heat radiation above the first radiating fin 21 and the second radiating fin 31 is larger than the heat radiation of the first fin crest 22, second fin crest 32, therefore also can produce the propelling movement air-flow of one rule above the first radiating fin 21 and the second radiating fin 31 respectively; Therefore, under same material characteristic and radiating condition, the radiating efficiency of this radiator is 3 times of the radiating efficiency of traditional rule radiator.Radiating efficiency of the present invention is high, effectively can improve the applied power of light fixture.
