Abstract

The utility model discloses a cooling device for a wind generating set. A plurality of heat radiating fins are paved on an integral bracket; water pipes are distributed on the heat radiating fins; cooling liquid flows into a water inlet pipe and flows out of a water outlet pipe; and the water inlet pipe is connected with a part to be subjected to heat radiating. The heat radiating fins include heat radiating fins for a generator and heat radiating fins for a frequency converter; and the water pipes are divided into a plurality of groups so as to respectively transmit heat of the generator and the frequency converter to the heat radiating fins for the generator and the heat radiating fins for the frequency converter. The water pipes are connected in parallel. Each heat radiating unit provided by the utility model is small in size and weight and convenient to maintain; the cooling device can be used for cooling by utilizing natural wind and is lower in cost and free of maintaining a fan motor as comparison with a forced cooling heat radiator; and each heat radiating unit is connected in a way that the water pipes are connected in parallel, so that cooling liquid is high in circulating speed to ensure that the heat radiating efficiency is high.

Description

The wind-powered electricity generation assembly cooling device
Technical field
The utility model belongs to wind-powered electricity generation unit cooling system technical field.
Background technology
Wind turbine generator is when work, and the heat that generator and frequency converter partly produce is bigger, needs the design cooling system that it is cooled off.Existing wind-powered electricity generation unit cooling system adopts dual mode more: air blast cooling is mode and natural wind cooling mode but.
When adopting natural wind cooling mode, fin is placed on the engine room cover top, utilizes the nature wind action to accomplish the exchange heat process of cooling liquid and outside air.Because the particularity of wind-powered electricity generation set engine room device operational environment of living in adopts natural wind cooling mode owing to can directly utilizing high aerial wind-resources to have special advantages.Continuous increase along with fan design power; The area of dissipation that need continue to increase fin guarantees radiating efficiency; This has also caused the volume of fin, weight all to continue to increase; So be difficult to finish the work smoothly by 1 staff when need dismantle, carry and installing when it is safeguarded.
Summary of the invention
The utility model provides a kind of wind-powered electricity generation assembly cooling device, to solve the technical problem that exists in the background technology.
For this reason; A kind of wind-powered electricity generation assembly cooling device of the utility model comprises that a plurality of fin are tiled on the integral support, and water pipe is laid on the said fin; Formation has the heat radiation wall of cooling effect; Cooling fluid flows into from the water inlet pipe of said water pipe, flows out from outlet pipe, and said water inlet pipe connects the parts of desire heat radiation.
Wherein, said fin is divided into generator and uses fin with fin and frequency converter, and said water pipe is divided into many groups, uses fin so that the heat of generator and frequency converter is guided to said generator respectively with fin and frequency converter.
Wherein, be parallel connection between said many group water pipes.
Use above cooling device to have following advantage:
1, the volume and weight of each heat-sink unit is less, is convenient to safeguard;
2, can utilize natural wind cooling, to compare cost lower with the air blast cooling radiator, and need not safeguard fan electromotor;
3, because each heat-sink unit adopts the mode of parallelly connected water pipe to connect, make that the cooling liquid circulation rate is faster, thereby make radiating efficiency higher.

Embodiment
Can be understood better for the shape, structure and the characteristics that make the utility model, below will enumerate preferred embodiment and combine accompanying drawing to be elaborated.
The cooling device of the utility model is made up of the less fin of a plurality of areas, according to the effect difference can be divided into generator with fin 1 and frequency converter with fin 2, be used for cooled electric generator and frequency converter respectively.Under the prerequisite that satisfies the heat radiation requirement; According to engine room cover superjacent air space size; In conjunction with their position relation of the size reasonable Arrangement of fin and be tiled on the integral support 5, water pipe is laid in fin inside, forms the heat radiation wall (as shown in Figure 1) with cooling effect.Cooling fluid flows into from the water inlet pipe 3 of water pipe, flows out from outlet pipe 4.Water inlet pipe 3 connects the parts of desire heat radiation, and the heat transferred that produces in the work is arrived the cooling device place.
A plurality of independently fin 1 connect through the mode that adopts the water pipe parallel connection.In the work, cooling liquid advances into a water inlet manifold 3 formally entering into cooling system, enters into cooling system then and accomplishes exchange heat, flows out via outlet pipe, gets back to respectively in the band thermal component, forms a complete cooling circuit.
The utility model makes the volume and weight of each fin all greatly reduce, and can be easily accomplishes dismounting, carrying and installment work to fin by 1 staff, for the maintenance work of wind-powered electricity generation unit cooling system brings great convenience.And owing to adopt the mode of parallel connection to connect, the cycle period of cooling liquid is also corresponding to be reduced; When making gap between each heat-sink unit reasonable, can make full use of the exchange that high aerial wind-resources is accomplished heat, improve radiating efficiency.
Use above cooling device to have following advantage:
1, the volume and weight of each heat-sink unit is less, is convenient to safeguard;
2, can utilize natural wind cooling, to compare cost lower with the air blast cooling radiator, and need not safeguard fan electromotor;
3, because each heat-sink unit adopts the mode of parallelly connected water pipe to connect, make that the cooling liquid circulation rate is faster, thereby make radiating efficiency higher.
More than be illustrative to the description of the utility model; And it is nonrestrictive; Those skilled in the art is understood, and within spirit that claim limits and scope, can carry out many modifications, variation or equivalence to it, but they will fall in the protection range of the utility model all.
