Power.
Fig. 6 is the cabin atmosphere Temperature and Humidity Control schematic diagram of the wind power generating set of embodiment according to the present invention.Such as Fig. 6
Shown, the air circulation of the air-cooled circulatory system carries out in an enclosure space, which includes by one layer of cabin
108, the air flow channel around two layer 109 of cabin and the internal stator coil (not shown) and iron core of generator 102 (does not show
Out).Entire enclosure space is by closing base cover plate door 124 (see Fig. 2), detachable cabin top cover 125 (see Fig. 2), removable cover
Plate 126 (see Fig. 2), dismountable cover plate 122 (see Fig. 3) and removable cover 123 (see Fig. 3) are isolated from the outside world and are formed.It is air-cooled to follow
Loop system can be coupled by the machine heat exchanger 117 that generates electricity with liquid-cooling circulating system, be handed over the heat in the air-cooled circulatory system with realizing
Liquid-cooling circulating system is given, or extracts heat to the air-cooled circulatory system from liquid-cooling circulating system.In particular, air-cooled circulation
System includes power generation machine heat exchanger 117, and the air inside generator 102 is sucked into generator by pipeline 102a, 102b and changes
Hot device 117 exchanges heat with the coolant liquid for flowing through power generation machine heat exchanger 117, and the air after heat exchange is sent generator heat exchange
Device 117 is flowed through and is flowed into inside generator 102 inside cabin 103.In the present embodiment, air circulation from power generation machine heat exchanger 117
Air side outlet start, flow through the courtyard 113 of cabin two-layer platform 107, along cabin two-layer platform upper space flow to
Generator 102, after flowing through electricity generator stator coil and iron core and being exchanged with its heat, flow through generator upper hot air pipe 102a and
Lower hot air pipe 102b is aspirated into power generation machine heat exchanger 117 again and carries out heat with liquid-cooling circulating system and exchanges.
In addition, as shown in Figure 6 and Figure 8, in the present embodiment, two power generation machine heat exchangers 117 are disposed with left-right symmetry
On one layer of platform 112 of cabin, every power generation machine heat exchanger 117 may include collection wind section 1171, heat exchanger core body 1172 and be air-cooled
The frequency conversion fan 1173 of circulatory system offer power.About 1171 wind section of collection is provided with air inlet, collects the enterprising of wind section 1171
Air port connects the upper hot air pipe 102a of generator 102, the lower hot air pipe of the lower air inlet connection generator 102 of collection wind section 1171
102b.In addition, courtyard 113 may be provided with temperature sensor 113a and humidity sensor 113b close to the side of pedestal 104, due to
The position is both that cabin inner circulating air flows through path again far from cabin wall area, therefore can avoid cabin wall surface temperature pair
The temperature and humidity value of the influence of measurement result, measured machine indoor environment is more representative.
In addition, may be provided with dehumidifier 150 in the present embodiment, in wind power generating set, which removes for runner
Wet machine, rotary dehumidifier may include regeneration wind blast pipe 150a, regeneration wind discharge pipe 150b and dry air air hose (not shown).By
It is lighter in density of moist air, therefore dehumidifier 150 can be arranged in two layer 109 of cabin, it is preferable that in order to reduce to platform sky
Between occupancy, dehumidifier 150 can be arranged into cabin two-layer platform tail portion close to the position of detachable cabin top cover 125.Dehumidifying
The entrance of the regeneration wind blast pipe 150a of machine 150 may be provided at cabin tail portion, and the outlet of regeneration wind discharge pipe 150b may be provided at
Cabin bottom, humid air is discharged into outside cabin 103, using this arrangement, is hung down since regeneration wind discharge pipe is close
Directly, ponding is easy to be discharged under the effect of gravity, is not easy to gather in regeneration wind discharge pipe 150b.Due to when power generation machine heat exchanger
After frequency conversion fan starting in 117, the air circulation in entire cabin, but the area between machine heat exchanger 117 and case change 116 that generates electricity
The air flow property in domain is poor, therefore can be by the outlet setting of the dry air air hose of the discharge dry air of dehumidifier 150 to hair
Motor heat exchanger 117 and case become the region between 116.In addition, in addition to it is traditional by the way of dehumidifier other than, also can be used
Other various ways for example, the mode that heat carrys out heat cycles air can be extracted from liquid-cooling circulating system, or give generator
Making alive carrys out the mode of heat cycles air by electricity generator stator coil.
In addition, in order to filter the circulation air in cabin, the salt particle in removal air and dust and other impurities to reach net
Change the purpose of air in cabin, cabin two-layer platform courtyard is also provided with filter at 113 position, to reduce extraneous intrusion machine
Influence of the air to machine indoor environment in cabin.In addition, in the present embodiment, in order to ensure air is according to above-mentioned design path stream
It is dynamic, while reducing influence of the case change to generator intake air temperature, it can also be arranged in the region that case becomes between 116 and pedestal 104 empty
Air screen barrier.
Disclosure for a better understanding of the present invention, hereinafter will be described in detail embodiment according to the present invention
