In this embodiment, the cooling device further includes a water pump 80, and the water pump 80 is communicated with the water inlet pipeline 31.
Specifically, the cooling device in this embodiment further includes a water tank 70 and a housing 60, the housing 60 is disposed outside the water tank 70, the water inlet pipeline 31 and the overflow pipeline 33 are both communicated with the water tank 70, the water tank 70 is disposed at the bottom of the wet curtain 10, and the water tank 70 is provided with a water receiving opening disposed opposite to the wet curtain 10.
The three-way valve is controlled to be started and stopped at regular intervals when the cold fan normally operates, and the starting and stopping time is comprehensively set according to the dry and wet state of the wet curtain 10, the air inlet speed, the flow of the water pump 80, the liquid distribution area and other factors, so that a liquid film on the surface of the wet curtain 10 can cover the exposed surface of the wet curtain 10 structure, and meanwhile, the thickness of the liquid film is moderate, and the wet curtain 10 is guaranteed to have the best evaporation efficiency.
The water pump 80 start-stop control logic: after the humidifying function of the cooling fan is started, the direction of the water outlet 51 of the three-way valve (or similar element) is in a conduction state, the water pump 80 is always in an opening state, and after the cooling fan runs for X minutes (the wet curtain 10 is ensured to be in a humidification state), the three-way valve (or similar element) enters a regular conduction and closing control program (mainboard program control). The three-way valve is opened for m seconds, closed for n seconds and opened for m seconds, and then opened and closed according to the regularity. The three-way valve is divided into a plurality of sections to be regularly started and stopped, and the three-way valve also belongs to the category of the patent. For example, the three-way valve is opened for m seconds, closed for n seconds, opened for a seconds, closed for b seconds, opened for m seconds, turned 8230, turned 8230
The three-way valve overflow 52 functions to return excess water provided by the water pump 80 to the water tank 70 when the three-way valve is closed, cooperating with the overflow; because the amount of water required by the wet curtain 10 is small, most of the water supplied by the water pump 80 is returned to the water tank 70 for recycling through the three-way valve overflow 52 and the overflow pipe. The three-way valve is arranged above the water outlet 51 of the three-way valve and used for controlling the amount of water flowing to the wet curtain 10, namely, the water amount is controlled by controlling the opening and closing time of the three-way valve, so that the wet curtain 10 is always in a wet state, and the thickness of a liquid film on the surface of the wet curtain 10 is moderate, so that the wet curtain 10 has the best evaporation efficiency.
The detailed working process comprises the following steps: after the cooling fan is turned on and humidification is turned on, the water pump 80 draws water from the water tank 70 and enters the three-way valve through the water inlet pipe, and then most of the water flows back to the water tank 70 for recycling from the overflow port 52 and the overflow pipe of the three-way valve. After running for X minutes to ensure that the wet curtain 10 is wet, the main board controls the three-way valve to enter a regular conduction and closing program. When the three-way valve is switched on, water enters the water diversion box (the water diversion piece 20 in this embodiment can be the water diversion box), and water is dispersed and flows onto the wet curtain 10 through the water diversion hole 21, so that the water supply amount of the wet curtain 10 is controlled, and the optimal evaporation cooling effect is realized. When the three-way valve is closed, no water is discharged from the water distribution box, namely, the water supply is stopped at the position of the wet curtain 10.
As shown in the flow chart of fig. 1. When the cooling fan is started and started, the three-way valves are consistently in an open state 3 minutes (or a certain time) before the whole machine is started to ensure that the wet curtain 10 is in a wet state, then the three-way valves are opened for m seconds, closed for n seconds and opened for m seconds, a regular start-stop control scheme supplies water to the wet curtain 10 to ensure that the wet curtain 10 is always in the wet state, and the thickness of a liquid film on the surface of the wet curtain 10 is moderate, so that the wet curtain 10 has the optimal evaporation efficiency.
Practical test verifies that the three-way valve is opened and closed according to the rule of opening 10 seconds and closing 60 seconds and is opened and closed according to the rule of opening 20 seconds and closing 60 seconds, and the evaporation cooling effect of two examples is compared with the universal scheme of the industry for supplying water to the wet curtain 10 consistently, and is improved by 13 percent and 18 percent respectively. Specific data are compared as shown in the following table.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: through the time control to the supply and the disconnection of supplying water, and then control the discharge on the wet curtain 10, make the evaporation efficiency that the wet curtain is in the preferred, can effectively promote thermantidote evaporation cooling effect. Compared with the conventional scheme, the temperature difference between the air inlet and the air outlet of the cooling fan can be 18%, and the effect is obvious.
