Description
Technical field
The utility model relates to a kind of wind generating technology, particularly relates to a kind of land straight drive blower.
Background technique
Wind-power electricity generation is closest to one of business-like renewable energy technologies, is the emphasis of Renewable Energy Development.The development trend of world today's wind generating technology shows as single-machine capacity increase, tower height rises and the progress of control technique.The wherein progressively increase of single-machine capacity, will directly cause the heat dissipating capacity of each parts in blower fan greatly to increase, natural ventilation cannot meet the cooling requirement of unit.The wind power generating set of current operation generally adopts the type of cooling of forced air cooling or liquid cooling, wherein lower-powered generator set many employings forced air cooling mode, and for medium-and-large-sized Wind turbines, then often adopts the mode of circulation liquid cooling could meet cooling requirement.But the complicated and somewhat expensive of single liquid cooling design, and single air cooling had both reduced the efficiency of generator, is difficult to again to reach the equipment cooling requirement that capacity increases day by day.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model will design one can meet the requirement of high-power land straight drive blower cooling heat dissipation, can raise the efficiency again and reduce the land straight drive blower of blower fan cost.
To achieve these goals, the technical solution of the utility model is as follows: a kind of land straight drive blower, comprises blade, cowling, generator, tower cylinder, cabin, generator air cooling pipeline, current transformer, transformer and external heat sink;
Described tower cylinder is middle void tower cylinder, and cabin is arranged on the top of tower cylinder, has vent hole between tower cylinder and cabin; Described cowling is installed on generator side, leaves blades installation hole; The side of described generator air cooling pipeline is connected with generator, opposite side is communicated to nacelle exterior, and fan is equipped with in end; Described external heat sink is connected with current transformer with generator respectively by two cooling liquid branch roads; In position steel checkerboard is laid, as vent hole bottom described cabin; Described transformer is lifted on bottom, cabin.
Working principle of the present utility model is as follows: by joint gap and the rational vent hole of each parts, make full use of the convection heat exchange of natural wind at blower interior, carry out air cooling heat exchange to whole blower fan.The generator amature that heat dissipating capacity is larger then passes through generator air cooling pipeline, and the heat produced is discharged to nacelle exterior; Generator unit stator and current transformer then utilize external heat sink to cool it, cooling liquid takes away heat through generator unit stator and current transformer internal heat pipeline under constant pressure and flow velocity, the cooling liquid absorbed after heat relies on forced air cooling to carry out heat exchange when flowing through external heat sink, and the cooling liquid after heat release flows back into generator unit stator and current transformer internal heat pipeline.
Compared with prior art, the utility model has following beneficial effect:
1, the utility model utilizes the assemblage gap of each parts and suitably offers vent hole, carries out air cooling heat exchange to blower fan.The utility model not only takes full advantage of the convection heat exchange of natural wind, decreases the complicated liquid cooling involved great expense of design, and without supplementary equipment, takes up an area few, and alleviate nacelle weight, significantly reduce cost.
2, the utility model adopts forced air cooling heat exchange to the larger generator of heat dissipating capacity and current transformer, utilize cooling liquid to flow through its internal heat pipeline and take away heat, the cooling liquid absorbed after heat relies on forced air cooling to carry out heat exchange when flowing through external heat sink, and the cooling liquid after heat release flows back into generator and current transformer internal heat pipeline.Make it work in normal temperature range, it is overheated to prevent, guard block.Main advantage is easy for installation, easy maintenance and inspection, by the working state of each cooling system of inspection that supervisory system can be very fast.
3, for making generator fully dispel the heat, by coupled for generator air cooling pipeline, pipeline opposite side is equipped with fan, and heat is discharged to nacelle exterior.Ventilation duct is light, easily install, and can better solve the problem of temperature rise that generator amature is in operation.
4, transformer is lifted on the bottom in cabin by the utility model, carries out heat exchange by air cooling.This not only reduces the loss of transmission current when transformer is placed in ground, effectively solve again the cooling problem of generator.And this transformer installing/dismounting is simple, allowing when not using ground crane, by the maintenance crane in cabin, transformer being down to ground and changing.

Fig. 1 is land straight drive blower air cooling system schematic diagram of the present utility model;
In figure: 1, blade, 2, cowling, 3, generator, 4, generator air cooling pipeline, 5, fan, 6, cabin, 7, current transformer, 8, external heat sink, 9, transformer, 10, tower cylinder.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.Be a kind of air cooling system of land straight drive blower as shown in Figure 1, natural wind enters blower fan by the gap of blade 1 and cowling 2, flows out from cowling 2 and generator 3 gap, has taken away the heat of cowling 2 inside and part generate electricity machine 3; The heat of another part generator 3 rotor is by generator air cooling pipeline 4, and the fan 5 in end is discharged to blower fan outside under acting on; Heat is taken away by the cooling liquid of its internal heat pipeline by stator and the current transformer 7 of generator 3, and final cooling liquid flows back into generator 3 and current transformer 7 after external heat sink 8 carries out forced air cooling heat radiation, completes a circulation; Transformer 9 is lifted on the bottom of cabin 6 bottom bracket, carries out air cooling by natural wind to it; In cabin 6, other assembly all carries out air cooling by natural wind convection heat exchange therein, natural wind by around tower cylinder 10, transformer 9 and suitable cabin 6 bottom vents enter cabin, flowed out by external heat sink 8 after heat exchange is carried out to its inside, and then complete the heat exchange of whole blower fan.
The utility model is not limited to above-mentioned mode of execution, any the utility model disclose technical scope in equivalent concepts or change, be all classified as protection domain of the present utility model.
