Cooling fan device for LED streetlamp

Abstract

The invention relates to a cooling fan device for an LED streetlamp. The cooling fan device comprises an outer shell, a large motor, a photothermic sensor and a plurality of multi-head fans. The multi-head fans are arranged in the outer shell and are separated through gratings, the lower portion of each grating is provided with a fixing plate, the two sides of each fixing plate are fixed to the inner wall of the outer shell through dismountable reinforcing strips, the large motor is arranged on the upper portions of the multi-head fans, the photothermic sensor is further arranged on the front upper portion of the large motor and is further provided with a temperature gauge, an LED streetlamp installation tank is arranged in the lower portions of the multi-head fans, and the two sides of the LED streetlamp installation tank are respectively provided with a drain outlet. Through the improvements, the cooling fan device has the advantages that adjustment is carried out to achieve cooling according to the internal temperature of the outer shell, the internal structure is firm, protective measures are taken among the multi-head fans so that the multi-head fans do not interfere with one another, the cooling fan device can be used under high-temperature and low-temperature environments and other severe environments and is high in strength, resistant to corrosion, excellent in fire resistance and good in venting practice, and pollution and blocking caused by dirt cannot be caused.

[0002] With the concept of energy saving, emission reduction and low-carbon environmental protection deeply rooted in the hearts of the people, LED lighting is more and more widely used, especially in the use of street lights in large public places. Although LED lighting equipment has the characteristics of energy saving and environmental protection, but in its lighting In the process, a large amount of heat energy will be generated, resulting in an excessively high internal junction temperature. If things go on like this, the internal chips will easily be burned out due to excessive temperature, especially for high-power LED street lights. Most of the existing technologies focus on LED street lights. The internal heat dissipation is improved, and then the external cooling is achieved by relying on the airflow of natural wind. However, this is very dependent on changes in the natural environment. In the prior art, fans are also used to cool down, but most of the fans are single-fan structures, and the wind power is limited. In some designs, because the temperature cannot be well controlled, the fan will continue to start regardless of whether it needs to cool down, which consumes unnecessary energy and does not meet the requirements of energy conservation and environmental protection. Moreover, the existing fan design lacks external protection, which is not suitable for use in harsh environments
