Description
Technical Field
The invention relates to the technical field of cabin heat dissipation of wind generating sets, in particular to a movable natural air cooling heat dissipation system of a wind generating set.
Background
In order to meet the increasing environmental protection requirements of people, how to reduce the noise of a wind generating set is a major technical problem faced by manufacturers of wind power generation complete machines in China. Researches show that mechanical noise of the unit can be greatly reduced if the heat exchange mode of cooling liquid or cooling oil outside the cabin and air is changed from the currently common forced air cooling mode to natural air cooling mode.
In order to avoid the wake flow influence area in the rotation process of the wind wheel so as to obtain an ideal heat dissipation effect, the natural air cooling radiating fins are usually fixed at the tail part of the engine room, so that the following two problems are brought: firstly, because the top of the wind generating set has limited space, the area behind the natural air cooling radiator is difficult to maintain; secondly, the speed of natural wind cannot be controlled and is often suddenly high and suddenly low, and practice proves that after the wind generating set runs at full power for a long time, if the wind speed suddenly drops, the heat dissipation effect of the cooling fins is greatly reduced, so that the cooling liquid or cooling oil is over-heated, and the machine set stops.

The invention aims to overcome the defects of the prior art and provides a movable natural air cooling heat dissipation system of a wind generating set.
In order to achieve the purpose, the technical scheme provided by the invention is as follows: a movable natural air cooling heat dissipation system of a wind generating set comprises a bracket, a telescopic rod, a natural air cooling radiator and a power device; the support mounting is on wind generating set's cabin, the one end and the support detachable connection of telescopic link, its other end transversely extend and with the detachable connection of nature forced air cooling radiator, power device installs on the support and is located the below of telescopic link for drive nature forced air cooling radiator is with the reciprocating motion of predetermined speed, thereby increase the decline of incoming flow wind speed in order to avoid the heat-sinking capability.
Furthermore, the power device has a self-locking function, and the natural air-cooled radiator can be fixed through self-locking of the power device.
Furthermore, the power device is a hydraulic cylinder, a piston rod of the power device is detachably connected with the natural air-cooled radiator, and the natural air-cooled radiator is fixed at a preset position by utilizing the principle that liquid cannot be compressed.
Compared with the prior art, the invention has the following advantages and beneficial effects:
the natural air-cooled heat dissipation system increases the incoming flow air speed by driving the natural air-cooled radiator to move, and avoids the reduction of the heat dissipation capacity of the natural air-cooled radiator caused by uncontrollable natural air speed, thereby maintaining the normal operation of the unit and improving the availability of the wind generating set; meanwhile, the radiator can be moved, so that the radiator can be moved forwards when the radiator needs to be maintained, and the problem that the original natural air-cooled radiator is difficult to maintain is solved.
