In the present embodiment, wind-driven generator 5 comprises blade, wheel hub, rotating shaft and generator amature, and wherein, blade pass is crossed wheel hub and is fixed in the rotating shaft, and rotating shaft is connected with generator amature.
In the present embodiment, for example: cooling unit can carry out cooling processing to the hot air that wind-driven generator 5 generates and generate and be used for cooling air that wind-driven generator 5 is cooled off.And then cooling unit can export to wind-driven generator 5 so that wind-driven generator 5 is cooled off with the cooling air that generates.Blade rotates under the driving of wind-force, drives the rotating shaft rotation through wheel hub, and then the rotation of rotating shaft meeting drive generator amature, thereby realizes the power generation process of wind-driven generator 5.
In the present embodiment, cooling unit can comprise: compressor 1, condenser 2 and vaporizer 3, compressor 1 are connected with vaporizer 3 with condenser 2 respectively, and condenser 2 is connected with vaporizer 3, and compressor 1 is connected with wind-driven generator 5 through transmission part 4.Then transmission part 4 drives compressor 1 operation when wind-driven generator 5 operations.Fig. 4 be among Fig. 3 wind-driven generator and compressor be connected schematic representation; In conjunction with Fig. 3 and shown in Figure 4; Particularly; Rotating shaft can comprise wind-driven generator transmission shaft 51 and the driving gear 52 that is connected with a joggle with wind-driven generator transmission shaft 51, and compressor 1 comprises compressor transmission shaft 11, and then transmission part 4 is installed on driving gear 52 and the compressor transmission shaft 11 so that wind-driven generator 5 is connected with compressor 1.When wind-driven generator 5 operations, 51 rotations of wind-driven generator transmission shaft are rotated to drive driving gear 52, and driving gear 52 drives 11 rotations of compressor transmission shaft so that compressor 1 operation through transmission part 4.In the present embodiment, transmission part can be strip-shaped members, and preferably, this strip-shaped members is a belt.
Compressor 1 is used for that the refrigerant vapour that comes from vaporizer 3 is carried out processed compressed and generates compressed steam and compressed steam is exported to condenser 2.Particularly, vaporizer 3 exports to compressor 1 with the refrigerant vapour of low temperature, low pressure, and the refrigeration agent of 1 pair of low temperature of compressor, low pressure carries out the compressed steam that processed compressed generates high temperature, high pressure.In the present embodiment, can connect through pipeline between compressor 1 and the vaporizer 3, so vaporizer 3 can export to compressor 1 with refrigerant vapour through pipeline; Can connect through pipeline between compressor 1 and the condenser 2, so compressor 1 can export to condenser 2 with compressed steam through pipeline.Preferably, compressor 1 is an opened compressor.
Condenser 2 is used for compressed steam is carried out condensation process, generates refrigeration agent, and refrigeration agent is exported to vaporizer 3.Particularly, condenser 2 carries out forced refrigeration through the air that comes from the outside to compressed steam, to realize the condensation process to compressed steam.Wherein, refrigeration agent is the high pressure saturated liquids.The process of compressed steam being carried out forced refrigeration through the air that comes from the outside is the process that condenser 2 and extraneous air flowing are carried out exchange heat; Condenser 2 is realized the compressed steam in the condenser 2 is carried out condensation process through carrying out exchange heat with the air that comes from the outside.In said process, compressed steam is emitted heat, thereby temperature reduces; The absorption of air heat that comes from the outside, thus temperature raises.
