Embodiment approach
[0028] As an embodiment of the present invention, a group of uniformly distributed and ring-shaped storage grooves 12 are opened on the outer wall of the protective ring 11, and a layer of diaphragm 13 is attached to the inner wall of the storage groove 12. The storage groove 12 The interior is filled with a water-absorbing ring 14 made of water-absorbing material; during work, the water-absorbing material for making the water-absorbing ring 14 can be cotton material, and the diaphragm 13 can separate the storage tank 12 from the protective ring 11, so that rainwater can flow into the storage tank. The inside of the tank 12 can be effectively preserved without being absorbed by the protective ring 11. When the rain is over and the sky is fine, the rainwater inside the storage tank 12 can absorb the surrounding heat when it evaporates, and at the same time, the cold air flows on the fan blades. Driven by 8, it can effectively flow into the interior of the housing 1, thereby enab...

The invention belongs to the technical field of heat dissipation devices, and specifically relates to a heat dissipation device for wind power generation. A connecting head is connected to the outer wall of the connecting head with a group of evenly distributed blades fixedly connected, a group of retaining nets are provided at the outer end of the housing, and a rotating plate and fan blades are connected to the side wall of the rotating shaft. The end of the rotating plate close to the retaining net is provided with a brush that fits the retaining net; the retaining net is composed of a group of staggered retaining rods, and the outer surface of the retaining rods is wrapped with water-swellable water-stop strip material. An annular protective ring; the present invention can effectively prevent external rainwater from flowing into the housing from the screen, and in the process of expansion and contraction of the protective ring, the protective ring can also act against dust and impurities located between the mesh openings of the screen. The effect of squeezing and pushing down greatly improves the cleanliness and use effect of the inside of the screen.
Description
technical field [0001] The invention belongs to the technical field of cooling devices, in particular to cooling devices for wind power generation. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. A wind turbine generally includes a wind wheel, a generator (including devices), a steering device (tail), a tower, and a limiter. The working principle of the wind turbine is relatively simple. The wind rotor rotates under the action of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates under the drive of the wind rotor shaft. To generate electricity, when the fan heat device of the wind power generator is in use, it cannot meet the fan heat inside the casing, and it cannot clean the baffle installed on the casing, which affects the use effect of the heat dissipation ...
