Effect of the invention is that:
1, by setting conductive fluid and heating wire in heat conducting pipe, by electric-heating-wire-heating conductive fluid, and the specific heat phase of conductive fluid To larger, a large amount of heat can be renewed, therefore blade is transferred heat to by conductive fluid again, temperature can be reached and transmit effect The effect that rate is higher and the retention time is longer.
It is set by the arrangement to heat conducting pipe so that conductive fluid Temperature Distribution in heat conducting pipe is substantially equal It is even.Since wind electricity blade is to want rotary work, when rotation, due to centrifugal force, conductive fluid will be to outside(Blade point Portion)It is mobile, and for the influence of the factors to heat conducting pipe such as exclude to expand with heat and contract with cold, complete 100% it can't be full of heat conduction in heat conducting pipe Liquid, therefore the conductive fluid meeting phase tip after heating is concentrated, so as to cause tip temperature and end region temperature uneven, so as to not only can The waste of heat is caused, can also cause portion that can form icing when serious.Therefore by by heat conducting pipe lower end Position is set as snakelike, so as to which when blade rotates, the portion tangent with rotation direction can be in part in snakelike It forms liquid to disconnect, so as to retain fluid within end so that the temperature of conductive fluid is substantially uniformly distributed.When blade temporarily stops After rotation stop is moved, partly flow to the conductive fluid of tip and can flow back into heat conducting pipe again and be uniformly distributed.By by the heat conduction of serpentine portion The length of pipe is set longer(It is the summation of other length of tube)So that it is maximum in the conductive fluid total amount of the section store, so as to Tip conductive fluid proportion shared in total amount is further reduced, further such that conductive fluid temperature in blade rotation process is equal Even distribution.(The heat conducting pipe of blade interior can not be integrally both configured to it is snakelike because if doing so since conductive fluid has Weight can cause the rotation of blade to be affected, while also blade interior stress distribution can be produced bigger effect, so as to It can cause the shortening of leaf longevity).
2, by being provided with rubber strip and by the specific setting to rubber strip in blade exterior so that while noise reduction So that blade surface generates heat, reduce the generation of icing phenomenon.
It realizes that the noise reduction in blade rotation process is existing known technology in the densely covered rubber strip of blade surface setting, grinds Study carefully how specifically being absorbed in for personnel to set every rubber strip to reach maximized noise reduction, but the inventors discovered that, if Two adjacent rubber strips are arranged in a crossed manner, this two rubber strips can be collided mutually in blade rotation process, and this collision Frictional heat can be generated, so as to which these rubber strips are while noise reduction is realized, can also be reached in blade by the setting of ad hoc fashion Contribute the effect of heat in surface.By setting adjacent two rubber strips one thick one thin, and the two diameter proportion is set, is made It obtains in blade rotation process, thinner rubber strip chattering frequency is higher(Wind-force is blown deformation, then due to rubber Characteristic and spring back), so as to higher with the collision frequency of a thicker rubber strip, and a thicker rubber strip chattering frequency is relatively It is low, the problem of being shaken in the same direction so as to avoid two rubber strips and collision frequency is caused to reduce, so as to generate opposite rub The heat is simultaneously transmitted on wind electricity blade surface by chafing according to the principle that even heat conducts.So as to be realized while noise reduction Noise-reducing components generate the purpose of heats, reach more preferably deicing effect.
3, exist in heat conducting pipe since the conductive fluid needs in heat conducting pipe are long-term, for the ingredient of conductive fluid It needs to adapt to the specific structure, by being improved its constituent content, appropriate reduces the content of water wherein, simultaneously Temperature according to residing for blade and other components are changed so that the conductive fluid more adapts to the specific ring of the present invention Border.
