Description

Technical Field

[0001] The invention belongs to the technical field of evaporative condensers, and in particular relates to a self-watering compact evaporative condenser. Background Art

[0002] The evaporative condenser is a heat exchange device commonly used in medium and large refrigeration and air-conditioning systems. In the prior art, the evaporative condenser mainly uses spray water as the cooling medium. The water forms a water film on the outside of the coil and exchanges heat with the process fluid in the coil. In this heat exchange process, the water that absorbs heat partially evaporates into water vapor, which is sucked away by the fan and discharged into the atmosphere. In this process, the evaporation of water takes away a large amount of heat, and the unevaporated water is collected in the water collection tank and recycled again through the circulating water pump and the return pipe. The fan of the system is arranged above the water collection tank, and the circulating water pump is located below the water collection tank, while the spray device, the cooling medium flow pipe and the packing layer are all arranged inside the water collection tank, and the static pressure tank is connected to the circulating water pump and the spray device through a water pipe;

[0003] Although the existing evaporative condensers perform well in medium and large systems, during the spray cooling process, if there is a problem with the nozzle or the design is improper, it may cause uneven distribution of the water film or even dry spots, thereby reducing the heat exchange efficiency. At the same time, because the thickness of the water film needs to be maintained at a certain thickness, it is convenient to maintain a high heat exchange efficiency, so the water pump needs to run continuously, which is not conducive to energy conservation. In addition, the nozzle water distribution, PVC water retaining filler and the setting of the circulating water tank are not conducive to controlling the overall volume of the evaporative condenser, and are not suitable for use in cooling systems with small cooling capacity.

[0046] like Figures 1 to 11 As shown, the end of the isolation shell 103 is fixedly connected with a bevel gear 1 214, wherein the surface of one round rod 1 209 is fixedly connected with a bevel gear 215, and the bevel gear 215 is meshingly connected with the bevel gear 1 214, and the surfaces of the two round rods 1 209 and the two round rods 226 are fixedly connected with a transmission wheel 1 216, and a transmission belt 1 217 is transmission-connected between two adjacent transmission wheels 1 216, and the surfaces of the round rods 1 209 are fixedly connected with a friction wheel 1 212, wherein the surfaces of two adjacent connecting plates 206 are respectively fixedly connected with friction wheels 213, and the two friction wheels 213 are transmission-connected, and the adjacent friction wheels 1 212 and friction wheels 2 213 are transmission-connected.

[0047] like Figures 1 to 11As shown, the inner bottom surface of the outer shell 101 is fixedly connected to a water baffle 219, and water guide grooves 220 are equidistantly provided on the surface of the water baffle 219. A ventilation groove 221 is provided on the upper surface of the water baffle 219 between any two adjacent water guide grooves 220. Water baffle plates 222 are symmetrically provided on both sides of the ventilation groove 221. The water baffle plates 222 are hinged on the surface of the water baffle 219.

The surface of the water baffle 224 is symmetrically fixedly connected to the surface of the water baffle 219. A wind shield arc plate 225 is provided between the two wind shield plates 224. The wind shield arc plate 225 is located directly above the two groups of outer ring cooling pipes 205, and the wind shield arc plate 225 is fixedly connected to the outer shell 101.

[0048] like Figures 1 to 11 As shown, the water storage area includes the area sandwiched between the interior of the shell 101 and the water barrier 219 , and a water level 237 is set inside the shell 101 .

[0049] like Figures 1 to 11 As shown, it should be noted that: rectangular vents are provided on the upper surface and the bottom surface of the housing 101, and the air inlet of the fan 102 is connected to the inside of the rectangular vent on the upper surface of the housing 101, so as to facilitate the air extraction work of the fan 102;

[0050] The surface of the housing 101 is provided with a liquid filling port (not shown in the figure) to facilitate the replenishment of water in the water storage area;

[0051] When the device is in cooling operation, the fluid to be cooled enters through one of the inlet and outlet pipes 201 and is discharged from the other inlet and outlet pipe 201 after being cooled by the device;

[0052] The round rod 1 209, the liquid inlet and outlet pipe 201 and the round rod 226 rotatably connected to the outer shell 101 are connected by means of an oil seal arranged on the side close to the inside of the outer shell 101 and a bearing arranged on the outside of the outer shell 101 to prevent the gas and liquid inside the outer shell 101 from leaking out. The rotational connection between the liquid inlet and outlet pipe 201 and the inner connecting disk 202 and the connection between the connecting disk 206 and the outer connecting disk 207 are also connected by the cooperation of the oil seal and the bearing to prevent the fluid introduced into the liquid inlet and outlet pipe 201 from leaking out.

[0053] Working principle: In this embodiment, when the device is cooling, the fan 102 and the motor 104 are powered on and run. The operation of the motor 104 drives one of the round rods 1 209 to rotate through the transmission of the bevel gear 1 214 and the bevel gear 2 215. The rotation of the round rod 1 209 is driven by a group of transmission wheels 1 216 and a transmission belt 1 217 arranged on the surface of the round rod 1 209, so that the corresponding round rod 226 rotates. The rotation of the round rod 226 drives the driving block 1 227 on its surface to rotate, and the hemispherical groove on the surface of the driving block 1 227 is meshed with the water transport cup 229, so that the connecting rope 228 moves along the surface of the driving block 1 227, and the water transport cup 229 on the surface of the connecting rope 228 is connected. When the water transport cup 229 moves to the lower position, the direction of the water storage tank on its surface rotates from downward to upward. During this process, under the constraint of the J-shaped channel of the constraint block 230, the water transport cup 229 puts water into the water storage tank on the surface of the water transport cup 229. When the water transport cup 229 storing water in the water storage tank moves to the surface of the driving block 1 227, the direction of the notch of the water storage tank gradually rotates from vertically upward to downward, and the water therein flows along the surface of the driving block 1 227 into the water receiving tank 234 provided on the surface of the water receiving platform 232. Because the water transport cup 229 is in sealing contact with the water receiving platform 232, the water flowing into the water receiving tank 234 flows into the flow equalizing box 233 through the connecting groove 236, and flows to the surface of the water guide rope 211 through the drain groove 235 on the surface of the flow equalizing box 233.

[0054] In this embodiment, another group of driving wheels 216 and driving belts 217 are driven to rotate another group of driving blocks 227, thereby another group of outer ring cooling tubes 205 and inner ring cooling tubes 203 are replenished with water.

[0055] In this embodiment, the round rod 1 209 rotates through the friction cylinder 210 on its surface to drive the water guide rope 211 to slide along the surface of the outer ring cooling tube 205, and the rotation of the round rod 1 209 is driven by the two sets of friction wheels 1 212 and friction wheels 2 213, so that the connecting disk 206 drives the outer ring cooling tube 205 to rotate around the central axis of the connecting disk 206, that is, the inner ring cooling tube 203 is driven by the connecting tube 204 to rotate along with the rotation of the outer ring cooling tube 205. In this process, the water flowing into the water guide rope 211 through the drainage groove 235 excessively adheres to the water guide rope 211, and as the water guide rope 211 slides on the surface of the outer ring cooling tube 205, it accelerates the replenishment of moisture on the surface of the moisture-conducting fibers of the outer ring cooling tube 205 and the inner ring cooling tube 203, thereby maintaining the stability of the water film on the surface of the outer ring cooling tube 205 and the inner ring cooling tube 203, thereby improving the cooling efficiency of the device;

[0056] In this embodiment, when the water guide rope 211 slides along the surface of the outer ring cooling tube 205, the restraining rope 2112 remains tight so that the water guide material 2113 remains loose during the sliding process, thereby storing more water;

[0057] In this embodiment, when the fan 102 is running, the gas enters the interior of the water baffle 219 from the rectangular vent at the bottom of the housing 101, and blows open the two water baffles 222 leaning against each other, so that the limit blocks 223 on the surface of the water baffle 222 abut against the corresponding limit blocks 223, so that the angle between the water baffle 222 and the notch plane of the ventilation groove 221 below it is less than 90 degrees, so that after the fan 102 stops running, the two water baffles 222 abut against each other under the action of gravity, so that the water dripping from the top of the water baffle 219 is not easy to drip out of the device from the ventilation groove 221, but flows back to the water storage area from the water guide groove 220, thereby reducing water waste;

[0058] In this embodiment, the gas blown out from the ventilation groove 221 is constrained by the wind shield plate 224 so that it blows toward the outer ring cooling tube 205 and the inner ring cooling tube 203 as much as possible. The gas located between the two sets of wind shield arc plates 225 is constrained by the wind shield arc plates 225 and turned to blow toward the outer ring cooling tube 205, thereby improving the heat exchange efficiency of the gas.

[0059] Embodiment 2, on the basis of embodiment 1, when the device is cooling, if the cooling power is small, it is not necessary to start the motor 104, and the water in the water storage area is guided to the water guide rope 211 in contact with the isolation plate 231 by the capillary phenomenon only through the self-absorption of water by the water-conducting fiber attached to the surface of the isolation plate 231, and a stable water film is formed on the surface of the outer ring cooling tube 205 and the inner ring cooling tube 203 through the water-conducting fiber on the surface of the inner ring cooling tube 203, the connecting tube 204, the outer ring cooling tube 205, the inner connecting disk 202 and the connecting disk 206, and the water vapor evaporated in the shell 101 is taken away by the operation of the fan 102, which is conducive to saving energy consumption of the device;

[0060] Embodiment 3, on the basis of embodiment 1, in order to further reduce the volume of the device, the round rod 226, the driving block 227, the connecting rope 228, the water transport cup 229, the restraining block 230, the water receiving platform 232, the flow equalizing box 233, the water receiving trough 234, the isolation shell 103, the motor 104, the bevel gear 214, the bevel gear 215, the transmission wheel 1 216 and the transmission belt 1 217 structures can be omitted, and only the isolation plate 231, the outer ring cooling tube 205, the inner connecting disk 202, the inner ring cooling tube 203 and the water-conducting fiber on the surface of the connecting disk 206 and the water-conducting rope 211 are used for self-absorption of water, so as to stably form a water film on the surface of the outer ring cooling tube 205 and the inner ring cooling tube 203 to cooperate with air cooling for cooling.
