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.

The embodiment is as follows: referring to fig. 1-2, a partitioned fireproof cross-flow open cooling tower comprises a tower body 1 and a transmission system 2 located on the upper portion of the tower body 1, wherein the tower body 1 comprises heat exchange cavities 11 on 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, radiating fins 5 are fixed in the heat exchange cavities 11, and a plurality of radiating fins 5 are suspended in the heat exchange cavities 11. Cooling water 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 water, and the air after absorbing heat enters the middle air chamber 12 and is discharged by the transmission system 2. The cooled cooling water 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 framework 13 is arranged, the framework 13 divides the heat exchange cavity 11 into a plurality of areas, fireproof partition plates 14 are fixed on two sides of the framework 13, and the fireproof partition plates 14 enable the radiating fins 5 of all the areas not to contact. When the heat sink 5 is ignited, the heat sink 5 can be kept in a small area, ensuring that the entire cooling tower is not damaged.

Referring to fig. 1-3, the heat sink 5 is made of PVC material with flame-retardant rating, and fire-retardant paint can be added to further submit the fire-retardant rating, which effectively increases the ignition temperature of the heat sink 5, and further reduces the risk of fire. The fire barrier 14 is in particular a non-asbestos fibre cement.

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, the heat dissipation fins 5 on both sides are arranged in an inverted-v shape. When the cooling water falls, the cooling water is not vertically dropped under the influence of horizontal wind power, and the cooling fins 5 are distributed in an inverted splayed shape at the moment, so that all the cooling water can pass through the cooling fins 5, and the heat dissipation effect is improved.

Referring to fig. 1 to 3, the heat sink 5 includes an air inlet 51 and an air outlet 52 in order from the outside to the center, the air inlet 51 facilitates air to enter a gap between the heat sink 5 and the heat sink 5, and the air outlet 52 prevents cooling water from being lost and allows air to pass through. The adjacent radiating fins are mutually matched, the air inlets form array air inlets, and the air outlets form dense air outlets with small cutting gaps, so that air can enter the interior of the radiator, and a large amount of water cannot be taken away. This greatly reduces 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 53 used for controlling the distance between the adjacent radiating fins 5 are arranged on the radiating fins 5. The 5 equidistance distributions of fin ensure that the cooling water can evenly disperse, prevent that the cooling water from falling the in-process under, the place that cooling water density is big receives the big, the ventilation of resistance of wind and the radiating effect that causes is poor.

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. 4-5, a baffle plate 10 is detachably connected to a position, corresponding to a heat sink, on the tower body 1, a plurality of lock bars 15 penetrating through the baffle plate 10 are welded in an aligned manner, a locking member 16 is slidably arranged on the baffle plate 10, a triangular limiting groove is formed in the head of each lock bar 15, and a plurality of wedge blocks 17 inserted into the limiting grooves are welded on the locking member 16; a fixed block 19 is fixed at the lower end of a locking piece 16 on the tower body 1, a screw 18 penetrating through the fixed block 19 is fixed on the locking piece 16, and a locking nut is connected on the screw 18 in a threaded manner. The nut is rotated, the nut pulls the screw rod 18 and the locking piece 16 to move downwards, so that the wedge 17 is inserted into the limiting groove, meanwhile, the inclined surface on the wedge 17 enables the baffle 10 to be tightly attached to the tower body 1, and the phenomenon that the baffle 10 has a gap with the tower body 1 to cause noise during the operation of equipment is avoided.

The implementation principle of the above embodiment is as follows: because the radiating fin 5 is very thin and has a complex structural curve, and the radiating fin 5 of a metal product is not rusty, the radiating fin is a PVC product in most cases; the PVC has lower ignition point, and the heat radiating fins 5 are divided into nine areas by the framework 13 and the fireproof partition plates 14, so that even if a part of the heat radiating fins 5 catch fire, only the local position of the heat radiating fins is damaged, the whole cooling tower is not influenced, and other parts of the cooling tower are not damaged.

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.
