[0019] Embodiment 1:

[0020] As Figs. 1-3 shown:

[0021] According to the utility model patent with the patent application number 202022375678.1, a wind guide mechanism applied to a plate-fin heat exchanger is disclosed; in the patent, a wind guide mechanism is arranged at the cold channel opening part of the plate-fin heat exchanger, that is, the cooler body. In order to avoid the front of the air inlet of the cooler body from being directly exposed to the wind, causing blockage, the utility model provides a pre-filtering type wind power cooler, which comprises a cooler body, a wind guide mechanism, a coarse filter part and a channel. The cooler body and the wind guide mechanism are both the existing technology disclosed in the utility model patent with the patent application number 202022375678.1.

[0022] In the utility model, the wind guide mechanism is installed at the opening part of the air cooling channel of the cooler body; the air outlet of the channel is sealingly communicated with the air inlet of the wind guide mechanism; the air outlet end of the coarse filter part 3 is sealingly communicated with the air inlet of the channel; the horizontal height of the air outlet end of the coarse filter part 3 is higher than that of the air inlet end of the coarse filter part 3; the air inlet end of the coarse filter part 3 is arranged downward and at the bottom of the coarse filter part 3; the air inlet end of the coarse filter part 3 is provided with a first air inlet grille plate 31 and a second air inlet grille plate 32; the first air inlet grille plate 31 and the second air inlet grille plate 32 are arranged in a V-shaped joint manner.

[0023] The pre-filtering type wind power cooler provided by the utility model sets the air inlet end of the coarse filter part 3 at the bottom and arranges it downward, so that the air inlet end of the coarse filter part 3 can take in air from the bottom, which can avoid direct contact between the air inlet surface and the horizontal wind, so that the impurities in the horizontal wind will not directly impact the air inlet surface of the coarse filter part 3, thereby reducing the likelihood of impurity accumulation causing air inlet blockage and reducing maintenance costs. In addition, due to the large wind power at high altitudes, impurities with large volume or mass, such as branches and stones, are often carried in the wind. In order to avoid such impurities from directly impacting the air inlet end of the coarse filter part 3 and causing damage or directly blocking the air inlet surface, the pre-filtering type wind power cooler provided by the utility model sets the first air inlet grille plate 31 and the second air inlet grille plate 32 in a V-shaped joint manner to protect the air inlet end of the coarse filter part 3. The V-shaped joint makes the first air inlet grille plate 31 and the second air inlet grille plate 32 form an inclined surface in the air inlet direction, which can reduce the impact force of impurities with large mass on the first air inlet grille plate 31 and the second air inlet grille plate 32, improve the structural strength of the first air inlet grille plate 31 and the second air inlet grille plate 32, and improve the protection effect of the air inlet end of the coarse filter part 3.

[0024] Due to the different components and volumes of impurities, if only a single layer of filter is provided, clogging is likely to occur, and the pre-filtering effect cannot be achieved. Therefore, the pre-filtering type wind power generation cooler provided by the utility model, preferably, the coarse filter part 3 comprises a first box body 33, a first sieve plate 34 and a second sieve plate 35, wherein: the first air inlet grille 31 and the second air inlet grille 32 are arranged at the bottom opening of the first box body 33; the upper part of the first box body 33 is provided with an air outlet of a communication channel; the first sieve plate 34 and the second sieve plate 35 are arranged inside the first box body 33; the first sieve plate 34 and the second sieve plate 35 are arranged between the air outlet of the first box body 33 and the bottom opening of the first box body 33; the first sieve plate 34 is located above the second sieve plate 35; and the screening size of the first sieve plate 34 is smaller than the screening size of the second sieve plate 35.

[0025] The pre-filtering type wind power generation cooler provided by the utility model is provided with the first sieve plate 34 with a smaller screening size at the upper part inside the first box body 33 and the second sieve plate 35 with a larger screening size at the lower part inside the first box body 33. In this way, the second sieve plate 35 can only intercept impurities with a larger volume, and pass impurities with a smaller volume, and the impurities with a smaller volume can be intercepted by the first sieve plate 34 above, and the impurities with a volume smaller than the screening size of the first sieve plate 34 can pass through to the next stage, thereby achieving the pre-filtering effect on the cooler body. By intercepting impurities of different sizes through the two sieve plates, all impurities can be prevented from being accumulated on the same filter layer, thereby avoiding clogging and reducing the maintenance cost. When the cooler stops working, the cooler body stops air intake, and since the first sieve plate 34 and the second sieve plate 35 are arranged in a stacked manner, the impurities adsorbed on the first sieve plate 34 by the wind force can freely fall and pass through the second sieve plate 35, and fall together with the impurities adsorbed on the second sieve plate 35, thereby further reducing the speed of impurity accumulation.

[0026] In order to facilitate the maintenance and cleaning and facilitate the removal of the sieve plates, the pre-filtering type wind power generation cooler provided by the utility model, preferably, the first sieve plate 34 and the second sieve plate 35 are inserted into the first box body 33 from the side surface of the first box body 33, and the side of the first sieve plate 34 and the second sieve plate 35 is provided with a pull handle 36. A limiting strip is arranged on the inner wall of the side surface of the first box body 33, the first sieve plate 34 and the second sieve plate 35 are inserted into the first box body 33, and the limiting strip is used for providing a mounting point for the first sieve plate 34 and the second sieve plate 35.

[0028] In order to further improve the pre-filtering effect, so as to reduce the impurity accumulation speed of the cooler body, the utility model provides a pre-filtering type wind power generation cooler, preferably, the inside of the channel is equipped with a dust filtering part 2; the dust filtering part 2 includes a second box 21, a ventilation grid plate 22 and filter cotton 23, wherein: the front and back of the second box 21 are provided with openings and correspond to the front and back ends of the channel respectively; the ventilation grid plate 22 is arranged in the second box 21; the ventilation grid plate 22 is in an arched structure, and the side of the arch top of the ventilation grid plate 22 faces the air inlet direction; the filter cotton 23 is attached to the arched surface of the ventilation grid plate 22.

[0029] When the pre-filtering type wind power generation cooler works, the gas filtered by the coarse filter part 3 enters the second box 21 from the gas outlet end of the coarse filter part 3 and passes through the ventilation grid plate 22, and the filter cotton 23 on the ventilation grid plate 22 further filters the gas. The pre-filtering type wind power generation cooler provided by the utility model increases the filtering area by arranging the ventilation grid plate 22 in an arched structure, improves the capacity of the ventilation grid plate 22 to accommodate impurities, prolongs the cleaning cycle, and can reduce the maintenance cost.
