The invention provides a cooling fan.
In an embodiment of the present invention, referring to fig. 1 to 4, the cooling fan includes a housing 100 having an air inlet and a wet curtain assembly detachably mounted on the air inlet; the wet curtain assembly comprises an upper wet curtain 200 and a lower wet curtain 201, the upper wet curtain 200 and the lower wet curtain 201 are installed on the air inlet from top to bottom, the cooling fan further comprises a water supply device for supplying water to the upper wet curtain 200 and a water receiving disc 203 installed on the shell 100 and located between the upper wet curtain 200 and the lower wet curtain 201, and a plurality of water distributing holes 204 distributed along the width direction of the lower wet curtain 201 are formed in the bottom of the water receiving disc 203.
The cooling fan utilizes liquid water to evaporate and refrigerates, and the effective surface area of the liquid water evaporation is increased by adopting a wet curtain. The water tank is arranged at the lower end of the cooling fan, the water supply device conveys water in the water tank to the upper end of the wet curtain, the water in the wet curtain flows from top to bottom, and redundant liquid water flows back into the water tank. Generally, the main body of the cooling fan is vertically arranged, the width of the air inlet and the air outlet is smaller, but the length of the air inlet and the air outlet is longer, and the length direction of the air inlet and the air outlet vertically extends. The wet curtain is usually arranged at the air inlet, and covers or fills the air inlet, so that the air inlet of the cooling fan must pass through the wet curtain. The wet curtain is longer rectangle, and when rivers flow to wet curtain bottom downwards from wet curtain top, the phenomenon of rivers uneven distribution appears easily in wet curtain's lower extreme, thereby causes wet curtain lower extreme partial lack of water to make effective evaporation area reduce, reduces the refrigeration effect of thermantidote.
In this embodiment, an upper wet curtain 200 and a lower wet curtain 201 are disposed at the air inlet and distributed vertically, and a water-receiving tray 203 is disposed between the upper wet curtain 200 and the lower wet curtain 201, where the water-receiving tray 203 is used for receiving water flowing down from the upper wet curtain 200, and the water flowing down from the upper wet curtain 200 is accumulated in the water-receiving tray 203 and is supplied to the lower wet curtain 201 through a water-distributing hole 204 formed at the bottom of the water-receiving tray 203. When the cooling fan works normally, the water supply flow of the water supply device to the upward wet curtain 200 is the sum of the evaporation capacity of the upward wet curtain 200 and the maximum water diversion flow of the water diversion holes 204 at the bottom of the water receiving disc 203, and a certain water level is kept in the water receiving disc 203, so that each water diversion hole 204 at the bottom of the water receiving disc 203 can supply water to the downward wet curtain 201 uniformly. The water supply device reduces the water supply amount to the upward wet curtain 200 when the water level in the water receiving tray 203 is high, and increases the water supply amount to the upward wet curtain 200 when the water level in the water receiving tray 203 is low; the water supply device can dynamically adjust the water supply amount according to the water level in the water receiving tray 203, so that the water level in the water receiving tray 203 is kept relatively fixed.
The water supply device comprises a diversion channel 202 which is arranged at the upper end of the upper wet curtain 200 and is provided with a plurality of diversion holes 204 at intervals along the width direction of the upper wet curtain 200. The bottom of the shunt groove 202 is provided with water diversion holes 204 which are arranged above the top end of the upper wet curtain 200 and are arranged at intervals along the width direction of the upper wet curtain 200. The bottom of the diversion trench 202 is also provided with an overflow hole 207, the side wall of the overflow hole 207 extends upwards, the water inlet of the overflow hole 207 is higher than the water inlet of the diversion trench 204, and the aperture of the overflow hole 207 is larger than the aperture of the diversion trench 204. Normally, the water level in the diversion channel 202 is lower than the water inlet of the overflow hole 207, the water supply at the top end of the upper wet curtain 200 is borne by the water diversion hole 204 of the diversion channel 202, and the overflow hole 207 does not supply water; when the water supply demand is large, the water supply flow of the water supply device is larger than the maximum water diversion flow of the water diversion holes 204 of the diversion trench 202, the water level in the diversion trench 202 rises, when the water level in the diversion trench 202 is higher than the water inlet height of the overflow holes 207, water flows to the top of the upper wet curtain 200 through the overflow holes 207, at this time, the diversion trench 202 supplies water to the upper wet curtain 200 through the overflow holes 207 and the water diversion holes 204, and the water flow of the upper wet curtain 200 increases. The evaporation amount of water in the wet curtain is related to the ambient temperature and the relative humidity, and the evaporation amount range of the upper wet curtain 200 is measured under the common environment, wherein the maximum water diversion flow of the water diversion holes 204 at the bottom of the diversion groove 202 is the sum of the minimum evaporation amount of the upper wet curtain 200 and the maximum water diversion flow of the water diversion holes 204 of the water receiving disc 203; the sum of the maximum water diversion flow of the water diversion holes 204 at the bottom of the diversion channel 202 and the maximum water diversion flow of the overflow holes 207 is larger than the sum of the maximum evaporation capacity of the upper wet curtain 200 and the maximum water diversion flow of the water diversion holes 204 of the water receiving tray 203. Meanwhile, the maximum water diversion flow rate of the water diversion holes 204 of the water receiving tray 203 is larger than the maximum evaporation amount of the lower wet curtain 201.
The present embodiment is not limited thereto, and in other embodiments, the diversion trench 202 may be replaced by a water diversion pipe disposed transversely and attached to the top of the upper wet curtain 200, and the bottom of the water diversion pipe is provided with a water diversion hole 204 facing the top of the upper wet curtain 200.
The water diversion holes 204 of the water pan 203 comprise a main water diversion hole 205 and a secondary water diversion hole 206, wherein the main water diversion hole 205 and the secondary water diversion hole 206 are uniformly distributed at intervals in the width direction of the lower wet curtain 201 respectively, and the aperture of the main water diversion hole 205 is larger than the aperture of the secondary water diversion hole 206; the main water diversion holes 205 and the auxiliary water diversion holes 206 are alternately arranged in sequence. The diversion capacity of the main water diversion holes 205 is larger than that of the auxiliary water diversion holes 206, and the adjacent two main water diversion holes 205 are far apart, when the main water diversion holes 205 are diverted to the lower wet curtain 201, the diversion of the different main water diversion holes 205 are mutually independent and can not be combined, so that the uniform distribution of water flow in the lower wet curtain 201 can be better maintained; the auxiliary water diversion holes 206 with smaller apertures are arranged between two adjacent main water diversion holes 205, so that the problem that the water flow at the upper end of the lower wet curtain 201 is difficult to cover the whole surface caused by the fact that the main water diversion holes 205 are far apart can be solved, and the whole lower wet curtain 201 can be fully immersed in the water flow.
The water receiving disc 203 holds a certain amount of water, and certain water sound is generated when water in the upper wet curtain 200 flows to the water receiving disc 203, so that the lower end of the upper wet curtain 200 is provided with the guide plate, the lower side edge of the guide plate is downwards inclined to extend into the water receiving disc 203, water in the upper wet curtain 200 smoothly flows into the water receiving disc 203 through the drainage of the guide plate, and larger noise generated when the water in the upper wet curtain 200 directly drops into the water receiving disc 203 is avoided, so that the silencing effect is better when the cooling fan works.
According to the technical scheme, the wet curtain is divided into the upper wet curtain 200 and the lower wet curtain 201, so that the length of the wet curtain is shortened, the problem of uneven water distribution at the lower end of the wet curtain caused by overlong downward flow paths of water flow in the wet curtain is avoided, and the infiltration of the whole wet curtain is ensured. By providing the water receiving tray 203 between the upper wet curtain 200 and the lower wet curtain 201, the water receiving tray is used for receiving the water flowing down from the upper wet curtain 200, accumulating and reforming the water and uniformly supplying water to the lower wet curtain 201.
In addition, referring to fig. 10, in order to improve the uniformity of the water flow in the wet curtain, a rectifying plate 300 may be further disposed inside the upper wet curtain 200 and/or the lower wet curtain 201, the rectifying plate 300 is a rectangular plate, the length direction of the rectifying plate 300 extends along the length direction of the water receiving tray 203, and the width direction of the rectifying plate extends along the height direction of the air outlet. The ventilation holes 301 are formed in the rectifying plate 300, the air inlet flow can pass through the wet curtain through the ventilation holes 301, meanwhile, when the air inlet flow blows through the rectifying plate 300, the surface of the rectifying plate 300 generates disturbed air flow, and water in the wet curtain needs to flow into the surface of the rectifying plate 300, so that water flow on the surface of the rectifying plate 300 can be blown away by the air inlet flow, and the water flow on the surface of the rectifying plate 300 is continuously irregularly disturbed, so that partial water flow flowing through the rectifying plate 300 can be distributed more uniformly in the whole when flowing downwards.
In order to facilitate assembly of the upper wet curtain 200, the water pan 203 and the lower wet curtain 201, referring to fig. 5 to 9, in another embodiment of the present invention, the upper wet curtain 200, the lower wet curtain 201 and the water pan 203 are all clamped on the housing 100.
