Description

Technical Field

[0001] The present invention relates to the technical field of air coolers, and in particular to a spray cooling device for an air cooler. Background Art

[0002] An air cooler is a closed, indirect contact cooling device widely used in the chemical industry. An axial flow fan blows the air below the cooler upwards, exchanging heat with the tube bundle and cooling the process medium in the tube bundle. The heat exchange effect of the air cooler depends largely on the ambient air temperature.

[0003] When the ambient air temperature is high in summer, the heat exchange effect of the air cooler is poor. In order to make the process medium reach the specified temperature, it is often necessary to start multiple spare air coolers, which not only increases the power load but also does not significantly improve the heat exchange effect.

[0004] Chinese patent application number CN202322917170.3 discloses a spray cooling device for an air cooler. The key technical features of the device are as follows: it comprises a main body and a water tank, with multiple sets of parallel heat sinks fixedly mounted on two opposing inner walls of the main body. Spray pipes are fixedly mounted between the inner walls of the main body, spaced apart from the heat sinks. A pump is provided on the surface of the water tank, connected to the spray pipes via a conduit. The inner cavity of the main body is provided with a cooling mechanism that cooperates with the heat sinks. The cooling mechanism comprises a fixed frame, a blower unit, a circulating humidifier unit, and a lifting unit. The fixed frame is an inverted U-shaped structure, with multiple sets of fixed frames disposed on either side of the heat sinks. The fixed frames are vertically slidably connected to the inner wall of the main body. This device solves the problem of poor heat exchange performance in existing air coolers, which often requires the use of multiple spare air coolers, increasing power load while not significantly improving heat exchange performance.

[0005] However, when the air cooler disclosed in the above patent uses a spray cooling device to spray cool the air cooler, the air flow direction is always the same, and the air entering the inner cavity of the air cooler cannot be guided in different states according to the ambient temperature, thereby being unable to adjust the time for cooling the air. When the external ambient temperature is high, the time for cooling the air through the inner cavity of the air cooler remains unchanged, resulting in insignificant air cooling, affecting the use effect of the air cooler.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0023] As Figures 1 to 11 shown, a spray cooling device for an air cooler according to the present invention includes: an air cooler body 1; an axial flow fan 3 fixedly installed on the top of the air cooler body 1; a radiator 4 fixedly installed inside the air cooler body 1; and a spray mechanism 2 for spray cooling the air cooler body 1.

[0024] The radiator 4 is composed of heat conducting plates and circulating pipes. A circulating water tank is externally connected to the circulating pipes, so that water can flow through the circulating pipes in a cycle. The heat conducting plates absorb the heat in the air inside the air cooler body 1 and exchange heat with the water flow in the circulating pipes, thereby cooling the inside of the air cooler body 1.

[0025] At the same time, start the axial flow fan 3 to discharge the cooled air inside the air cooler body 1.

[0026] Through the action of the radiator 4, the air inside the air cooler body 1 can be preliminarily cooled.

[0027] The spray mechanism 2 includes: a water pump 21 fixedly installed outside the air cooler body 1; a water inlet pipe 22 connecting the water inlet end of the water pump 21 to the air cooler body 1; a water outlet pipe 23 communicating with the water outlet end of the water pump 21; a shunt pipe 24 communicating with the water outlet pipe 23; an atomizing nozzle 25 communicating with the shunt pipe 24; and the shunt pipe 24 is rotatably connected to the water outlet pipe 23.

[0028] A plurality of shunt pipes 24 are provided, and a plurality of atomizing nozzles 25 are connected to each shunt pipe 24, thereby expanding the spraying range of the atomizing nozzles 25.

[0029] A water storage cavity is provided at the bottom of the inner cavity of the air cooler body 1, and clear water is stored in the water storage cavity.

[0030] Since the cooling effect of the radiator 4 is limited, the radiator 4 is further cooled by the spraying mechanism 2, thereby improving the cooling effect on the air inside the air cooler body 1.

[0031] The water pump 21 is started, and the clear water in the water storage cavity is sucked out through the water inlet pipe 22 and conveyed into the shunt pipe 24 through the water outlet pipe 23, and then atomized and sprayed out through the atomizing nozzle 25. The sprayed water mist adheres to the radiator 4. Through the evaporation heat absorption of the water mist, the radiator 4 can be quickly cooled and dissipated, thereby improving the cooling effect on the air inside the air cooler body 1.

[0032] The spraying mechanism 2 further includes: a swinging assembly 26 that drives the atomizing nozzle 25 to swing; the swinging assembly 26 includes: a first reciprocating lead screw 262 rotatably installed inside the air cooler body 1; a first power source 261 that drives the first reciprocating lead screw 262 to rotate, and the first power source 261 is fixedly installed outside the air cooler body 1 through a mounting bracket; a moving plate 263 threadedly connected to the first reciprocating lead screw 262; a limiting rod 264 that limits the moving plate 263, the limiting rod 264 penetrates the side wall of the moving plate 263, and both ends of the limiting rod 264 are fixedly installed inside the air cooler body 1; a rack 265 fixedly installed at the bottom of the moving plate 263; a linkage gear 266 fixedly sleeved on the shunt pipe 24; the linkage gear 266 meshes with the rack 265.

[0033] When the water pump 21 is started, the first power source 261 is started at the same time. The first power source 261 drives the first reciprocating lead screw 262 to rotate, and the first reciprocating lead screw 262 drives the moving plate 263 to move. Through the limiting action of the limiting rod 264, the limiting rod 264 makes a reciprocating movement along the axial direction of the first reciprocating lead screw 262.

[0034] The moving plate 263 drives the rack 265 to reciprocate, and the rack 265 drives the linkage gear 266 to reciprocate, thereby driving the shunt pipe 24 to rotate reciprocally, and further driving the atomizing nozzle 25 to swing reciprocally.

[0035] Through the reciprocating swing of the atomizing nozzle 25, the spraying range of the atomizing nozzle 25 can be further expanded, so that the spraying range of the atomizing nozzle 25 fully covers the radiator 4, improving the cooling effect on the radiator 4, and further improving the cooling effect on the air in the inner cavity of the air cooler body 1.

[0036] It is supplemented here that the first power source 261 is preferably a motor.

[0037] The spraying mechanism 2 further includes: a stirring assembly 27 for stirring clear water; the stirring assembly 27 includes: a cylinder 271 rotatably installed in the air cooler body 1; stirring blades 272 fixedly installed on the cylinder 271, there are multiple stirring blades 272, and the multiple stirring blades 272 are evenly distributed along the circumferential direction of the cylinder 271; a round rod 273 rotatably installed on the cylinder 271; a linkage frame 274 slidably connected to the round rod 273, a guiding groove is formed on the linkage frame 274, the round rod 273 is slidably installed in the guiding groove, a sliding strip is fixedly installed on the linkage frame 274, a sliding groove is formed in the air cooler body 1, and the sliding strip is slidably installed in the sliding groove; a linkage plate 275 fixedly connected to the linkage frame 274; a driven bevel gear 277 coaxially connected to the cylinder 271; a driving bevel gear 276 meshingly connected to the driven bevel gear 277, the driving bevel gear 276 is rotatably installed on the air cooler body 1; a linkage member 278 of the first linkage power source 261 and the driving bevel gear 276, the linkage member 278 is preferably a synchronous pulley and a synchronous belt, there are two synchronous pulleys, one synchronous pulley is fixedly sleeved on the first reciprocating lead screw 262, the other synchronous pulley is coaxially connected to the driving bevel gear 276, and the two synchronous pulleys are driven by the synchronous belt.

[0038] The water storage cavity is externally connected with a cold source, which can refrigerate the clear water in the water storage cavity, thereby ensuring the cooling effect after the clear water is atomized; the cold source preferably has a refrigeration unit.

[0039] When the first power source 261 is started, it can drive the first reciprocating lead screw 262 to rotate, thereby driving the linkage member 278 to operate, the linkage member 278 drives the driving bevel gear 276 to rotate, the driving bevel gear 276 drives the driven bevel gear 277 to rotate, the driven bevel gear 277 drives the cylinder 271 to rotate, and the cylinder 271 drives the stirring blades 272 to rotate, so as to realize the circumferential stirring of the clear water.

[0040] While the cylinder 271 drives the stirring blades 272 to rotate, it can synchronously drive the round rod 273 to rotate, the round rod 273 drives the linkage frame 274 to move, the linkage frame 274 drives the sliding strip to slide in the adjacent sliding groove, and through the limiting effect of the sliding strip and the sliding groove, the linkage frame 274 makes a linear reciprocating movement driven by the round rod 273.

[0041] The linkage frame 274 drives the linkage plate 275 to make a linear reciprocating movement, so as to realize the axial stirring of the clear water.

[0042] Through the arrangement of the stirring assembly 27, both the circumferential stirring of the clear water and the axial stirring of the clear water are realized, so that when the clear water is cooled, the cooling is more uniform, and the cooling effect of the clear water on the radiator 4 is ensured.

[0043] The spraying mechanism 2 further includes: a flow guiding component 28 for guiding air; the flow guiding component 28 includes: an installation opening formed on the air cooler body 1, and a filter net 281 fixedly installed in the installation opening; an installation frame 282 fixedly installed on the air cooler body 1; a flow guiding plate 283 rotatably installed in the installation frame 282, the flow guiding plate 283 is rotatably installed in the installation frame 282 through a rotating shaft, there are multiple flow guiding plates 283, and the multiple flow guiding plates 283 are driven through a transmission member 285; a second power source 284 for driving the flow guiding plate 283 to rotate, the second power source 284 is fixedly installed on the outer side of the installation frame 282, and the output end of the second power source 284 is fixedly connected to the rotating shaft of any one flow guiding plate 283.

[0044] When the air cooler body 1 is not in use, the multiple flow guiding plates 283 are all arranged vertically, and adjacent flow guiding plates 283 are arranged in mutual contact, and the two flow guiding plates 283 at the top and bottom are both in mutual contact with the inner wall of the installation frame 282.

[0045] At this time, the multiple flow guiding plates 283 can close the installation frame 282. On the one hand, it reduces the dust adhering to the filter net 281, thereby reducing the maintenance of the filter net 281. On the other hand, it reduces the evaporation of clear water and avoids frequent water addition.

[0046] When starting the axial flow fan 3, start the second power source 284 to drive the adjacent rotating shaft to rotate, thereby driving the adjacent flow guiding plates 283 to rotate. Through the setting of the transmission member 285, multiple flow guiding plates 283 can be synchronously driven to rotate.

[0047] The transmission member 285 is preferably a chain and a sprocket, which ensures the synchronous rotation of the multiple flow guiding plates 283, and a tensioning mechanism can be arranged on the chain to make the chain and the sprocket always mesh, thereby further ensuring the synchronous rotation of the multiple flow guiding plates 283.

[0048] Through the setting of the filter net 281, the air entering the inside of the air cooler body 1 can be filtered, avoiding dust from entering the inside of the air cooler body 1 and polluting the clear water.

[0049] A temperature sensor is installed on the air cooler body 1, which can sense the annular temperature and set three threshold ranges, namely T1, T2, and T3, and T1 < T2 < T3.

[0050] When the outside air temperature is within the range of T1, at this time, there is no need to start the radiator 4 and the spraying mechanism 2. When starting the axial flow fan 3, start the second power source 284, thereby driving the flow guiding plate 283 to rotate to the first state, as Figure 10 shown.

[0051] At this time, the outside air flows obliquely upward along the deflector 283, reducing the time for the air to stay in the air cooler body 1 and improving the air flow efficiency.

[0052] When the outside air temperature is within the range of T2, it is necessary to start the radiator 4 at this time. While starting the axial flow fan 3, start the second power source 284, so as to drive the deflector 283 to rotate to the second state, as Figure 10 shown.

[0053] At this time, the outside air flows horizontally along the deflector 283, increasing the time for the air to stay in the air cooler body 1, so that the radiator 4 can effectively cool the air.

[0054] When the outside air temperature is within the range of T3, it is necessary to start the radiator 4 and the spraying mechanism 2 at this time. While starting the axial flow fan 3, start the second power source 284, so as to drive the deflector 283 to rotate to the third state, as Figure 10 shown.

[0055] At this time, the outside air flows obliquely downward along the deflector 283, further increasing the time for the air to stay in the air cooler body 1. Moreover, the air flowing obliquely downward contacts the water surface of the water storage cavity, thereby realizing further cooling of the air and improving the air cooling effect.

[0056] As can be seen from the above, through the setting of the diversion assembly 28, the deflector 283 can be rotated to different states according to different environmental temperatures, so as to realize the diversion of the air entering the inner cavity of the air cooler body 1 in different states, and further effectively improve the heat dissipation and cooling effect of the inner cavity of the air cooler body 1.

[0057] It is supplemented here that the second power source 284 is preferably a motor.

[0058] The spraying mechanism 2 further includes: a cleaning component 29 for cleaning the filter screen 281; the cleaning component 29 includes: a second reciprocating lead screw 292 rotatably installed in the installation frame 282, a driving member 291 drivingly installed between the second reciprocating lead screw and the deflector 283; a brush 293 threadedly connected to the second reciprocating lead screw 292; a fixing rod 294 for limiting the brush 293, both ends of the fixing rod 294 are fixedly installed in the installation frame 282; a collection box 296 for collecting dust on the filter screen 281, the collection box 296 is fixedly installed at the bottom of the installation frame 282, a collection opening one is opened at the bottom of the installation frame 282, a collection opening two is opened at the top of the collection box 296, and the collection opening one and the collection opening two are communicated with each other; an air pump 295 fixedly installed on the installation frame 282; an air outlet pipe 298 connecting the air outlet end of the air pump 295 and the deflector 28; an air inlet pipe 297 connecting the air inlet end of the air pump 295 and the collection box 296.

[0059] The rotating shaft is a hollow tube, the flow guide plate 283 is a rectangular plate with a cavity, and air outlet holes are formed in the flow guide plate 283 and are communicated with the cavity. Each rotating shaft is communicated with the adjacent flow guide plate 283, the air outlet pipe 298 is communicated with each rotating shaft, and the air outlet end of the air outlet pipe 298 is rotatably connected with the rotating shaft. A filter plate is installed in the collection box 296, so that the gas pumped by the air pump 295 is clean gas. A sealing door is installed on the collection box 296. When it is necessary to clean the dust collected in the collection box 296, the sealing door can be opened for cleaning.

[0060] When cleaning the filter net 281, the air pump 295 and the power source two 284 are started. The power source two 284 can drive a plurality of flow guide plates 283 to rotate synchronously, and drive the second reciprocating lead screw 292 to rotate through the driving member 291. Under the limiting action of the fixing rod 294, the brush 293 moves reciprocally along the axial direction of the second reciprocating lead screw 292. Through the reciprocating movement of the brush 293, the dust on the air inlet side of the filter net 281 can be cleaned, ensuring the filtering effect of the filter net 281.

[0061] The cleaned and fallen dust enters the collection box 296 through the collection opening one and the collection opening two. At the same time, the air pump 295 extracts the air in the collection box 296 through the air inlet pipe 297. At this time, a negative pressure is generated in the collection box 296, so that the outside air enters the collection box 296 through the collection opening one and the collection opening two, and the cleaned and fallen dust quickly enters the collection box 296 with the air flow, improving the collection efficiency of the dust.

[0062] Since a filter plate is installed in the collection box 296, the gas pumped by the air pump 29 is clean gas, and sequentially passes through the air outlet pipe 298 and the rotating shaft and enters the flow guide plate 283, and then is discharged through the air outlet holes. Since the flow guide plate 283 rotates circumferentially along the rotating shaft, the high-pressure gas discharged from the air outlet holes performs air outlet cleaning on the filter net 281, further improving the cleaning effect on the filter net 281.

[0063] In addition, the rotation of the flow guide plate 283 enables the high-pressure gas discharged from the air outlet holes to clean the inside of the installation frame 282 and the flow guide plate 283 itself.

[0064] It is supplemented here that the driving member 291 is preferably a synchronous pulley and a synchronous belt.

[0065] In the present invention, through the setting of the spraying mechanism 2, the radiator 4 can be comprehensively sprayed with water mist, and the clear water in the water storage cavity can be stirred to make its cooling uniform, and the air entering the inner cavity of the air cooler body 1 can be guided in different states according to the ambient temperature, thereby effectively improving the heat dissipation and cooling effect in the inner cavity of the air cooler body 1.

[0066] All standard parts used in the present invention can be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
