As shown in fig. 1, the present invention provides a vacuum moisture regaining anti-freezing cooling tower, which comprises a cooling heat dissipation box, a water storage tank 100 and a water pump 300; wherein, a sewer pipeline 241 used for connecting with external equipment is arranged on the cooling water heat radiation box body 200; the water storage tank 100 is connected with the cooling water heat dissipation tank body 200, and a heater is arranged on the water storage tank 100; the water inlet pipe 320 of the water pump 300 is connected with the water storage tank 100, the water outlet pipe 310 of the water pump 300 is connected with the cooling water heat dissipation tank 200, and the water outlet pipe 310 of the water pump 300 is provided with a heat insulation layer 311 with a set length.
In operation, the water pump 300 pumps the cooling water in the water storage tank 100 into the cooling water heat sink body 200 through the water outlet pipe 310, and outputs the cooling water to the external device through the drain pipe 241 after being cooled by the cooling water heat sink body 200. The heater arranged in the water storage tank 100 can prevent the cooling water in the water storage tank 100 from freezing or can be quickly thawed when the cooling water in the water storage tank 100 is frozen, and meanwhile, the insulating layer 311 arranged on the water outlet pipeline 310 can prevent the cooling water in the water outlet pipeline 310 from freezing, so that the cooling tower can be normally started and operated in cold winter.
The "external equipment" is equipment that uses the cooling water output from the cooling tower.
Further, the cooling tower further comprises a first water level detector 110, a second water level detector 120, a water replenishing pipeline 130 and a controller; wherein, the first water level detector 110 and the second water level detector 120 are both arranged on the inner side wall of the water storage tank 100, and the first water level detector 110 is higher than the second water level detector 120; the water replenishing pipeline 130 is communicated with the water storage tank 100; the controller is connected with the first water level detector 110 and the second water level detector 120, and when the water level in the water storage tank 100 is lower than the first water level detector 110 and higher than the second water level detector 120, the controller controls the water replenishing pipeline 130 to be opened for replenishing water; when the water level in the water storage tank 100 is higher than the first water level detector 110, the controller controls the water replenishing pipe 130 to be closed; when the water level in the storage tank 100 is lower than the second water level detector 120, the controller issues a stop command.
It is understood that the water replenishing pipe 130 may be connected to an existing water source, and the water replenishing pipe 130 may be provided with a valve so that the controller can control the opening or closing, and of course, the controller may directly control the water source to supply or cut off water. Wherein, the stability of water supply of the water storage tank 100 is ensured by monitoring the water levels through the first water level detector 110 and the second water level detector 120,
it should be noted that the water storage tank 100 is further provided with an alarm device, the alarm device is connected to the controller, and when the water level is lower than the second water level detector 120, the controller can control the alarm device to give out an alarm and send out a shutdown instruction, so as to shutdown the cooling tower.
Further, the cooling water heat dissipation tank 200 includes a water distribution tank 210, the water distribution tank 210 is communicated with a water outlet pipeline 310 of the water pump 300, and the water distribution tank 210 is provided with a first water leakage hole 211.
Wherein, the cooling water heat dissipation tank 200 is a cylindrical structure, and the inside thereof has a heat dissipation space, and the water distribution tank 210 is an annular structure and is disposed at the inner side of the cooling water heat dissipation tank 200; the cooling water in the water outlet pipeline 310 can be output to the water distribution tank 210 and leak out through the first water leakage hole 211 on the water distribution tank 210. Among them, the first water leakage holes 211 are uniformly and densely distributed on the water distribution groove 210, so that the cooling water can uniformly leak from the water distribution groove 210.
Further, the cooling water heat dissipation box 200 further includes a plurality of sets of fins 220, the plurality of sets of fins 220 are disposed below the water distribution tank 210, the plurality of sets of fins 220 are stacked, each of the plurality of fins 220 is provided with a plurality of second water leakage holes 221, and the positions of the second water leakage holes 221 on two adjacent fins 220 are staggered. The staggered position means that the projections of the second water leakage holes 221 of the two adjacent heat dissipation fins 220 in the vertical direction are not overlapped, so that the water leaked from the upper heat dissipation fin 220 firstly falls to the solid part of the lower heat dissipation fin 220 for heat dissipation, and then flows to the second water leakage holes 221 of the lower heat dissipation fin 220 for falling, thereby realizing the layer-by-layer heat dissipation and improving the heat dissipation effect.
Further, the cooling water heat-dissipating case 200 further includes a fan 230, and the fan 230 is disposed at the top of the cooling chamber heat-dissipating case. The fan 230 can generate induced draft during operation, and the cooling water dropped uniformly can be cooled after the air passes through each layer of the radiating fins 220, so that the cooling purpose is achieved.
Further, the cooling water heat-dissipating case 200 further includes a water collecting tank 240, the water collecting tank 240 is disposed below the heat-dissipating fins 220, and the drain line 241 is connected to the water collecting tank 240.
The cooling water dropped from the heat radiating fins 220 is finally collected in the water collecting tank 240, and is outputted to an external device through a drain line 241 connected to the water collecting tank 240.
The cooling water heat sink 200 is disposed above the water storage tank 100. Therefore, the cooling water heat dissipation box body 200 can form a three-dimensional layout, and the occupied space is saved.
Wherein, the water storage tank 100 may also be a cylinder structure, and the cooling water heat dissipation tank 200 and the water storage tank 100 are an integrated structure. That is, the cooling water radiator tank 200 and the storage tank 100 may have a common tank, and the header tank 240 may partition the common tank into two parts, such that the upper part forms the cooling water radiator tank 200 and the lower part forms the storage tank 100, thereby facilitating the design and manufacture of the cooling tower and simplifying the molding process.
Further, a drain valve 400 is further provided at the bottom of the water storage tank 100. When the water storage tank 100 needs to be cleaned, the drain valve 400 can be opened, so that the cooling water in the water storage tank 100 can be quickly discharged through the drain valve 400, and the operation is convenient.
Further, the water outlet pipe 310 is provided with a water outlet pipe 330, and at the end of production, the cooling water in the water outlet pipe 310 can be discharged through the water outlet pipe 330, so as to avoid freezing in the pipe in winter.
