Problems solved by technology

[0003] The cooling of the traditional LED lamp housing is usually achieved by free air cooling or blowing by a cooling fan. The latter cooling fan is more difficult to prevent rain, and so far no electric axial fan with a turbine-type waterproof cover has been installed on the top of the lamp housing to prevent The lamp housing is cooled by external airflow and has the function of preventing rainwater

Embodiment Construction

[0084] The cooling of the traditional LED lamp housing is usually achieved by free air cooling or blowing by a cooling fan. The latter cooling fan is more difficult to prevent rain, and so far no electric axial fan with a turbine-type waterproof cover has been installed on the top of the lamp housing to prevent The lamp housing is cooled by external airflow and has the function of preventing rainwater.

[0085] A turbine-type axial fan actuated by wind force or heat flow has a closed top and is surrounded by a plurality of radial discharge blades with gaps and stacked at the same oblique angle, with a shaft downward in the middle. When there is no wind, if the electric axial flow fan pumps airflow to the axial airflow inlet to the inside of the turbine waterproof cover, the turbine formed by the discharge blades can be rotated and the axial airflow inlet will be sent to the airflow inlet. The incoming air is discharged to the surroundings.

[0086] At present, the heating dev...

Abstract

The invention is to install an electric axial flow fan with a turbine-type waterproof cover that can prevent rainwater on the top of the closed heat dissipation lamp shell of a high-power lamp. When the electric axial flow fan is powered on and operates, the top airflow flows through the closed heat dissipation lamp shell. The hot air flows around the top of the lamp shell toward the middle, and upwards into the axial airflow inlet on the lower side of the turbine waterproof cover, and is discharged to the surroundings through the radial discharge blades. When using high-power lamps, the hotter lamp shell can be The top creates an external airflow cooling effect without hindering its waterproof sealing effect.

Description

technical field [0001] A turbine-type axial fan actuated by wind force or heat flow has a closed top and is surrounded by a plurality of radial discharge blades with gaps and stacked at the same oblique angle, with a shaft downward in the middle. When there is no wind, if the electric axial flow fan pumps airflow to the axial airflow inlet to the inside of the turbine waterproof cover, the turbine formed by the discharge blades can be rotated and the axial airflow inlet will be sent to the airflow inlet. The incoming air is discharged to the surrounding; [0002] At present, the heating devices installed inside the enclosed space, such as high-power lamps, are usually made of heat-conducting materials with a closed top as a heat-dissipating casing to facilitate the upward divergence of heat energy and prevent rainwater from entering. An electric axial flow fan driven by electric energy is set to send the airflow into the turbine type waterproof cover. When the electric axial ...
