Problems solved by technology

As far as the current situation is concerned, in order to reduce the temperature inside the wind turbine, the main heat dissipation method is to install an air conditioning system, or introduce the external air from the lower platform space to the inner platform space, and then perform heat exchange and heat dissipation in the inner platform space. Single heating method with large limitations
However, there are certain defects in these technologies. For example, the cooling method of the air-conditioning system, the air-conditioning equipment is industrial air-conditioning, which is expensive and occupies a large space, and also requires other auxiliary equipment; and the way of heat exchange in the inner platform space, due to The space of the inner platform is small, and the gas has no time to fully exchange heat, so it enters the inside of the heating cabinet. Due to the low heat exchange efficiency, the temperature of the internal components of the cabinet will rise and the alarm will be triggered, which will affect the normal operation of the unit.

Embodiment 1

[0030] Such as figure 1 As shown, the present invention provides a wind cooling device, including a tower 1 and a nacelle 2; a support plate 24 is provided in the tower 1; a water cooling mechanism is provided on the support plate 24; Heat exchange mechanism; the cabin 2 is arranged on the top of the tower tube 1; the interior of the cabin 2 is provided with an arc-shaped deflector 6; the present invention can choose whether to use dual mechanisms to dissipate heat at the same time according to the external weather temperature during use. When the temperature of the outside air is low, the water cooling system can be turned off, and the outside air can be directly used to dissipate heat from the generator set 4. The present invention makes full use of the outside air flow to dissipate heat, and the heat dissipation effect is obvious and the heat dissipation efficiency is high.

Embodiment 2

[0032] refer to Figure 1~2 , the present embodiment 2 adopts the following preferred scheme on the basis of embodiment 1: the heat exchange mechanism includes a hot air bin 26; the upper end of the hot air bin 26 is communicated with an air intake pipe 12; Exchange chamber 27; the upper end of the heat exchange chamber 27 is communicated with an air outlet pipe 11; the air outlet pipe 11 extends along the inside of the air inlet pipe 12; the air outlet pipe 11 extends along the inside of the air inlet pipe 12, which is conducive to reducing the size of the device Occupies volume, saves space, and is easy to install and operate.

[0033] In this embodiment, the connection between the heat exchange chamber 27 and the air outlet pipe 11 is provided with a wind guide wheel 19; the bottom of the heat exchange chamber 27 is evenly spaced with air guide funnels 20; the air guide funnels 20 will The hot air chamber 26 communicates with the heat exchange chamber 27; the air guide fun...

Embodiment 3

[0036] Such as figure 1 As shown, the present embodiment 3 adopts the following preferred scheme on the basis of the above embodiments: the water cooling mechanism includes a water storage tank 23 fixed on the support plate 24; the side end of the water storage tank 23 is provided with a water outlet pipe 16; A water pump 15 is installed at the end of the water outlet pipe 16; the water outlet pipe 16 is connected to the water inlet of the water pump 15; a condenser 22 is installed above the water storage tank 23; a hot water pipe is arranged on the condenser 22 21 and cold water pipe 28; the cold water pipe 28 is connected with the water storage tank 23; under the effect of the condenser 22, the water is continuously pumped into the hot water pipe 21 by the water pump 15 to cool the outside air, so that the gas and the generator set 4 has a larger temperature difference, thereby improving the heat dissipation effect; one end of the hot water pipe 21 runs through the hot air c...

Abstract

The invention specifically discloses a wind cooling device, which is characterized in that: it includes a tower and a nacelle; a support plate is arranged inside the tower; a water cooling mechanism is arranged on the support plate; a heat exchange device is arranged above the water cooling mechanism Mechanism; the engine room is arranged on the top of the tower; the inside of the engine room is provided with an arc deflector. During the use of the present invention, it is possible to choose whether to use dual mechanisms to dissipate heat at the same time according to the external weather temperature. When the external air temperature is low, the water cooling system can be turned off, and the external air is directly used to dissipate heat from the generator set. The present invention makes full use of the external air flow for heat dissipation , the heat dissipation effect is obvious, and the heat dissipation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a wind cooling device and a generator set. Background technique [0002] As a safe and clean renewable energy, wind energy has been paid more and more attention by people. Wind power generation equipment is a power generation equipment that relies on capturing wind energy and converting kinetic energy into electrical energy. In modern large-scale wind turbines, with the increase of the power generated by a single machine, the heat generated by the internal components of the wind turbine is increasing. Therefore, it is necessary to design a new type of cooling device for the wind turbine to dissipate the heat in the wind turbine, so as to ensure the safe and trouble-free operation of the wind turbine. [0003] Generator set cooling device is a device installed on the generator set to dissipate the heat of the generator set, so as to effectively reduce the heat generate...
