Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example (b): referring to fig. 1-2, a cross-flow open cooling tower using non-combustible cooling fins comprises a tower body 1 and a transmission system 2 located at the upper part of the tower body 1, wherein the tower body 1 comprises heat exchange cavities 11 at two sides and a middle air chamber 12 located in the two heat exchange cavities 11, a water inlet device 3 and a water outlet device 4 are respectively arranged at the upper end and the lower end of each heat exchange cavity 11, cooling fins 5 are fixed in the heat exchange cavities 11, and a plurality of cooling fins 5 are suspended in the heat exchange cavities 11. The cooling liquid flows into the heat exchange cavity 11 from the water inlet device 3 and then uniformly scatters on the radiating fins 5, at the moment, the transmission system 2 starts to work, so that the middle air chamber 12 forms negative pressure, external low-temperature air enters the heat exchange cavity 11 from two sides to exchange heat with the cooling liquid, and the air after absorbing heat enters the middle air chamber 12 and is discharged by the transmission system 2. The cooled cooling liquid is continuously put into use through the water outlet device 4.

Referring to fig. 1-2, since the heat sink 5 is made of PVC, the ignition point is low, and open fire is likely to occur. Since the heat dissipation fins 5 are very thin, one of the heat dissipation fins will be completely spread out in a short time after being ignited, resulting in damage to the entire cooling tower. Therefore, the radiating fins made of PVC materials are changed into stainless steel materials, the ignition point of the radiating fins 5 is improved and is far greater than the highest temperature of the cooling liquid. Thereby avoiding the possibility of fire.

Referring to fig. 1-2, the moving system comprises a motor, a reducer and a fan 21 positioned at the top of the tower body 1, wherein the fan 21 is aligned in the middle air chamber 12; the motor and the speed reducer drive the fan 21 to rotate, and further the hot air in the middle air chamber 12 is finally discharged out of the tower body 1. The water inlet device 3 comprises a water dispersion tank and water dispersion heads positioned at the bottom of the water dispersion tank, and the water dispersion heads are uniformly distributed in an array manner. The water outlet device 4 comprises a cold water tray 41 for receiving cooling water and a water outlet pipe. The water inlet device 3 conveys cooling water in other equipment to the heat exchange chamber, and the water outlet device 4 conveys the cooled cooling water to other equipment for cooling, so that a closed loop is formed.

Referring to fig. 1 to 3, the heat sink 5 includes an air inlet section 51 and an air outlet section 52 in sequence from the outside to the center, the air inlet section 51 facilitates air to enter a gap between the heat sink 5 and the heat sink 5, and the air outlet section 52 is used for preventing cooling water from losing and allowing air to pass through. Adjacent fin is mutually supported, and the air inlet section forms array air intake, and the air-out section forms intensive air outlet that cuts the clearance very little, has so both guaranteed that the air can get into inside, can not take away a large amount of water simultaneously. This greatly reduces the cooling water loss. A steel pipe 54 is arranged in the tower body 1, the radiating fins 5 are hung on the steel pipe 54, and protrusions used for controlling the distance between every two adjacent radiating fins 5 are arranged on the radiating fins 5. The radiating fins 5 are distributed at equal intervals, so that the cooling liquid can be uniformly dispersed, and the problem that in the falling process of the cooling liquid, the radiating effect is poor due to large wind resistance and small ventilation at the place with large density of the cooling liquid is avoided.

Referring to fig. 1-6, baffles are detachably arranged at the two sides of the tower body 1 corresponding to the heat exchange cavity, the baffles are fixed on the tower body 1 through bolts, and when the radiating fins need to be cleaned or replaced, the radiating fins 5 are directly cleaned or replaced by detaching the baffles.

Referring to fig. 2, a ladder stand 6 is vertically arranged on the tower body 1. The ladder 6 is used for people to enter the top to maintain the fan 21.

Referring to fig. 4-6, since the fan 21 generates vibration when working, and the vibration makes the bolt loosen, the anti-loosening device 7 for preventing the bolt from loosening is disposed on the bolt of the tower body 1, the anti-loosening device 7 includes a limiting sleeve 71 sleeved on the bolt, four limiting rods 72 connected to the limiting sleeve 71 in a circumferential array manner by screw threads, and an expansion link for connecting two limiting sleeves 71, the expansion link includes screw sleeves 74 respectively fixed to the limiting sleeves 71 and screw rods 73 connected between the two screw sleeves 74 by screw threads, and the screw threads at the two ends of the screw rods 73 are opposite screw threads. When the telescopic rod is used, firstly the telescopic rod is adjusted, two adjacent limiting sleeves 71 can be sleeved on the bolt head, and then the limiting rod 72 is screwed, so that the limiting rod 72 abuts against the bolt head.

Referring to fig. 4-6, two telescoping rods can also be connected for the same stop collar 71.

The implementation principle of the above embodiment is as follows: the radiating fins 5 are very thin, have complex structural curves, and are made of plastic in most cases because the radiating fins of metal products cannot resist rusting; the plastic has lower ignition point, so the PVC radiating fin is changed into the stainless steel radiating fin, the ignition point of the radiating fin is improved and is far higher than the highest temperature of the cooling liquid, and the possibility of fire is further avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
