[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
[0083] The cooling of traditional LED lamp housings is often achieved by free air cooling or by cooling fans. The latter’s cooling fan is difficult to prevent rainwater. So far, no electric axial fan with a turbine-type waterproof cover is installed on the top of the lamp housing. The lamp shell is used for external cooling airflow cooling, and has the function of rainproof.
[0084] A turbine-type axial flow fan actuated by wind or heat flow has a closed top and is surrounded by a plurality of radial discharge blades superimposed at the same oblique angle with gaps between each other, with a shaft downward in the middle When there is no wind, if the electric axial fan pumps the air to the axial air inlet to the inside of the turbine-type waterproof cover, the turbine formed by the exhaust blades can rotate and send the axial air inlet The incoming air flow is discharged to the surroundings.
[0085] At present, heating devices installed in enclosed spaces, such as high-power lamp...

The present invention provides an electric axial-flow fan (202)having turbine type waterproof enclosure, which is rainproof and installed at the top portion of sealed heat dissipation housing (101)of a high power lamp, so when the electric axial-flow fan (202) is operated, the airflow passes through the top portion of lamp housing, which is relatively hotter, of the sealed heat dissipation housing and is concentrated towards the center, then leaded to upwardly enter an axial airflow inlet port formed at the bottom of the turbine type waterproof enclosure, thereby being exhausted to the surroundings through radially-arranged exhaust blades (207), thus when the present invention being applied in a high power lamp, an air cooling effect by external airflow can be provided to the top portion, which is relatively hotter, of the lamp housing, without influencing the waterproof sealing effect.
Description
Technical field [0001] A turbine-type axial flow fan actuated by wind or heat flow has a closed top and is surrounded by a plurality of radial discharge vanes superimposed at the same oblique angle with gaps between each other, with a shaft downward in the middle When there is no wind, if the electric axial flow fan pumps the air flow to the axial air inlet to the inside of the turbine-type waterproof cover, the turbine formed by the exhaust blades can rotate and send the axial air inlet Incoming air flow is discharged to the surrounding; [0002] Current heating devices, such as high-power lamps and lanterns, installed in enclosed spaces are usually made of heat-conducting materials and have a closed top as a heat sink to facilitate the upward dissipation of heat and prevent rainwater from entering. The present invention is on the top of the heat sink of the lamp. An electric axial fan driven by electricity is installed to send the airflow into the turbine-type waterproof cover....
