In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
The wet curtain liquid distributor is one of the core components of the air-conditioning fan, and the performance of the liquid distributor directly influences the evaporative cooling performance of the air-conditioning fan.
The uneven problem of current liquid distributor ubiquitous export cloth liquid causes wet curtain to correspond the position local dry or cross liquid stifled hole phenomenon, seriously influences the cooling ability of wet curtain evaporimeter. Analysis shows that the liquid distribution unevenness is mainly caused by two aspects: firstly, wet curtain structure itself, wet curtain is formed by the cementing of the corrugated sheet of many piece absorbent, so the mass transfer ability between the corrugated sheet is relatively weak. Secondly, due to the structure of the wet curtain liquid distributor, the existing liquid distributor is limited by the structure, a certain interval usually exists between two adjacent liquid distribution holes, and the interval distance is generally equal to the distance between the wet curtain corrugated sheets which is several times of the distance between the two adjacent liquid distribution holes, so that the wet curtain sheets positioned between the two liquid distribution holes cannot obtain direct liquid distribution, and finally the wet curtains are dried.
In order to wet the corrugated sheets of the wet curtain as uniformly as possible, it is common to arrange as many liquid distribution holes as possible on the liquid distributor, but this would result in an increase in the corresponding water pump flow rate and an increase in the cost.
For this, as shown in fig. 1 to 4, the present embodiment provides a wet curtain cloth dispenser capable of dispensing wet curtain cloth, and the wet curtain is made of absorbent paper. The wet curtain is made of absorbent paper and has certain water absorption, and after being soaked by the cloth fluid, the wet curtain can maintain a normal evaporation state for a period of time T1 under a working condition of certain air volume, so that the wet curtain does not need continuous water supply cloth fluid, the evaporation capacity and the temperature performance of the wet curtain are kept unchanged within T1 time after disposable cloth fluid is finished, and in the process, because the water supply quantity is zero, the wind resistance of the wet curtain is reduced, and the air volume is increased.
In one embodiment, the wet curtain liquid distributor comprises a tank body 1 and a siphon flow channel assembly arranged in the tank body 1, wherein the siphon flow channel assembly comprises a first flow channel structure 2 and a second flow channel structure 3. The first flow channel structure 2 is arranged in the box body 1 and penetrates through the bottom wall of the box body 1, and the upper end and the lower end of the first flow channel structure 2 are both provided with openings; the second flow channel structure 3 is arranged in the box body 1 and comprises a plate-shaped part 301 positioned above the first flow channel structure 2 and a cylindrical part 302 connected with the plate-shaped part 301 and surrounding the first flow channel structure 2, a first gap is formed between the plate-shaped part 301 and the top end of the first flow channel structure 2, a second gap is formed between the cylindrical part 302 and the first flow channel structure 2, and a third gap is formed between the bottom end of the cylindrical part 302 and the bottom wall of the box body 1.
In this embodiment, the height of the first flow channel structure 2 determines the highest water storage level of the tank 1, a third gap is formed between the bottom end of the cylindrical portion 302 of the second flow channel structure 3 and the bottom wall of the tank 1, the third gap forms a siphon flow channel inlet, the height of the inlet determines the liquid level height in the final siphon drain tank 1, a second gap is formed between the cylindrical portion 302 and the first flow channel structure 2, the second gap forms a siphon flow channel, and the space between the height of the first flow channel structure 2 in the tank 1 and the height of the siphon flow channel inlet is the effective water storage volume of the siphon tank 1. Since the wet curtain can maintain the performance unchanged in the time T1 after one liquid distribution, obviously, the water storage time of the box body 1 should be matched with the wet curtain. In order to adjust the water storage and discharge period of the tank 1, the height of the first flow channel structure 2 and the height of the siphon flow channel inlet formed by the second flow channel structure 3 and the bottom wall of the tank 1 can be adjusted during design, so that the water storage period of the tank 1 is consistent with T1.
The working process and principle of the wet curtain liquid distributor are shown in fig. 5 to 8, and the working process is roughly divided into 4 stages: firstly, as shown in fig. 5, a small flow of water is continuously pumped into the tank 1 from the water tank of the air conditioning fan or the cooling fan, at this time, the siphon flow channel assembly is substantially a communicating vessel structure, the liquid level in the siphon flow channel is consistent with the liquid level in the tank 1 and slowly rises, and the stage is a water storage stage; next, as shown in fig. 6, when the liquid level in the siphon flow channel reaches the top of the first flow channel structure 2, the water in the siphon flow channel is about to flow out through the first flow channel structure 2, and this point is a siphon critical point; after reaching the siphon critical point, as shown in fig. 7, the liquid level continues to rise, the water in the siphon flow channel flows out through the inside of the first flow channel structure 2, meanwhile, because the siphon flow channel is closed, the water in the tank body 1 is continuously discharged through the siphon flow channel under the action of siphon force, and the stage is a water discharging stage; with the rapid discharge of the feed water, the liquid level in the tank 1 is continuously decreased, as shown in fig. 8, when the liquid level in the tank 1 is lower than the lowest point of the second flow channel structure 3, the closure of the siphon flow channel is broken, so that the siphon force disappears, the water discharge stage is finished, and at the same time, the tank 1 enters the water storage stage again because the feed water is still continuous. The above is a complete water storage-drainage cycle. In the above-mentioned circulation, through setting up siphon runner assembly, make drainage flow be greater than the feedwater flow, thereby can realize under the prerequisite that does not increase water pump flow, promote instantaneous cloth liquid flow's purpose, when this wet curtain cloth liquid ware is connected in cloth liquid groove 4, can provide instantaneous great cloth liquid flow for cloth liquid groove 4, consequently, can satisfy every cloth liquid hole 401 and have great cloth liquid flow after increasing cloth liquid hole 401's in the cloth liquid groove 4 quantity, can be as even as far as possible soak each corrugated sheet on the wet curtain, avoid the wet curtain to take place the phenomenon of drying.
