The specific embodiment
Referring to accompanying drawing, a kind of high-powered LED lamp heat loss through convection device, this heat abstractor is made of heat radiation plate body 1, on a side of heat radiation plate body 1, is provided with the mounting groove 3 of LED lamp plate 2, on the another side of heat radiation plate body 1, is provided with one group of heat radiation projection 4.
During use, LED lamp group 8 is installed on the LED lamp plate 2, LED lamp plate 2 is installed in the mounting groove 3 of heat radiation plate body 1, the heat that LED lamp group 8 produces is transmitted on the heat radiation plate body 1, and heat radiation plate body 1 dispels the heat by heat radiation plate body 1 one group of heat radiation projection 4 and that be provided with on the another side of heat radiation plate body 1 own.Because heat radiation projection 4 has increased the area of dissipation of heat radiation plate body 1, the heat that LED lamp group 8 is transmitted on the heat radiation plate body 1 in time distributes.
For further increasing the area of dissipation of heat radiation plate body 1, in described both sides, be provided with auxiliary heat dissipation plate 5 at heat radiation plate body 1 mounting groove 3, auxiliary heat dissipation plate 5 is provided with one group of auxiliary heat dissipation projection 6.
The present invention produces cross-ventilation for making at auxiliary heat dissipation plate 5 positions, increases the radiating effect of auxiliary heat dissipation plate 5, is provided with cross-ventilation hole 7 between the auxiliary heat dissipation projection 6 that is provided with on the described auxiliary heat dissipation plate 5.Cross-ventilation hole 7 makes the up and down formation cross-ventilation of air at auxiliary heat dissipation plate 5, improves the radiating efficiency of auxiliary heat dissipation plate 5.Lower material consumption and heat sink weight simultaneously.
The present invention is for improving the radiating efficiency of heat radiation projection 4 and auxiliary heat dissipation projection 6, and described one group of heat radiation projection 4 is in the curved setting of short transverse.Described one group of auxiliary heat dissipation projection 6 is in the curved setting of short transverse.
The heat radiation plate body 1 that the present invention relates to, heat radiation projection 4, auxiliary heat dissipation plate 5 and auxiliary heat dissipation projection 6 adopt the aluminium alloy one-shot forming, guarantee the good looking appearance and the radiating efficiency of product, lower the manufacturing cost of product, owing to the windage that has reduced wandering hot plate that is provided with in cross-ventilation hole 7, improve wandering hot plate safety in utilization simultaneously.
