[0025] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0026] Referring to Figures 1 - 5 , the present invention provides a fin-tube type direct water-cooled evaporative heat exchanger with intelligent adaptive multi-condition high-efficiency heat transfer, including a housing 1, a fin tube 4 is installed in the housing 1, a flow meter 42 is installed at the liquid inlet end of the fin tube 4, the flow meter 42 is electrically connected to a controller, the liquid inlet end of the housing 1 is connected to a water transfer pump 11, a spray assembly, and a cleaning assembly through a four-way pipe 12, the liquid outlet end of the housing 1 is connected to a drainage pump 5, the liquid outlet end of the drainage pump 5 is connected to the liquid inlet end of the water transfer pump 11, and the controller is used to control the drainage pump 5, the water transfer pump 11, the spray assembly, and the cleaning assembly to work.

[0027] The water transfer pump 11 is used to transport the liquid into the housing 1, and the drainage pump 5 is used to drain the water in the housing 1. The liquid outlet end of the housing 1 is connected to the drainage pump 5 through a fourth pipeline 51.

[0028] The present invention controls the drainage pump 5, the water delivery pump 11, the spray assembly, and the cleaning assembly through a controller, and can intelligently and adaptively make the drainage pump 5, the water delivery pump 11, the spray assembly, and the cleaning assembly work respectively under different working conditions, so that the present invention can effectively adjust the heat exchange efficiency in real time and reduce energy consumption when the load changes or the ambient temperature fluctuates.

[0029] In a further optimized solution, the liquid outlet end of the flowmeter 42 is connected to the finned tube 4 through the water inlet pipe 41. The flowmeter 42 can monitor the flow rate entering the finned tube 4 in real time; and the monitored flow rate data is fed back to the controller in real time.

[0030] In a further optimized solution, the liquid outlet end of the finned tube 4 is connected to a water outlet pipe 43, and a first temperature detector is installed in the water outlet pipe 43. The first temperature detector is electrically connected to the controller. Through the first temperature detector, the temperature of the liquid flowing out of the finned tube 4 can be monitored in real time, and the monitored temperature data is fed back to the controller in real time.

[0031] A plurality of second temperature detectors are installed in the housing 1. The second temperature detectors are electrically connected to the controller, and the second temperature detectors are used to monitor the temperature inside the housing 1.

[0032] In a further optimized solution, the liquid inlet end of the housing 1 is connected to the four-way pipe 12 through the first pipe 13, and a first solenoid valve 14 is installed in the first pipe 13. The first solenoid valve 14 is electrically connected to the controller. The controller can open or close the first pipe 13 through the first solenoid valve 14.

[0033] In a further optimized solution, the spray assembly includes a second pipe 15 connected to the four-way pipe 12. A second solenoid valve 16 is installed in the second pipe 15. One end of the second pipe 15 extending into the housing 1 is connected to a plurality of atomizing parts through a plurality of branch pipes respectively. The plurality of atomizing parts are arranged along the axial direction of the finned tube 4, and the branch pipes are fixedly connected to the inner wall of the housing 1.

[0034] The plurality of atomizing parts are arranged at equal intervals along the axial direction of the finned tube 4, so that the plurality of atomizing parts can effectively spray water mist to fully cover the finned tube 4.

[0035] In a further optimized solution, the atomizing part includes a plurality of atomizing nozzles 17, and the nozzles of the atomizing nozzles 17 face the finned tube 4. The water mist sprayed by the atomizing nozzles 17 can be effectively sprayed on the finned tube 4.

[0036] In a further optimized solution, the second solenoid valve 16 is electrically connected to the controller. The controller can open or close the second pipe 15 through the second solenoid valve 16.

[0037] Further optimized solution. The cleaning component includes a water pipe reel 2 fixedly installed at a corner inside the housing 1. A hose 33 is wound around the water pipe reel 2. One end of the hose 33 is connected to a third pipe 21, and the end of the third pipe 21 extending outside the housing 1 is connected to a four-way pipe 12. The other end of the hose 33 is connected to a ring 31. A number of spray nozzles 32 are embedded on the inner wall of the ring 31. All the spray nozzles 32 are connected to the third pipe 21 through the ring 31. A third solenoid valve 22 is installed in the third pipe 21, and the third solenoid valve 22 is electrically connected to the controller. The water pipe reel 2 can automatically wind up the hose 33, enabling the ring 31 to move effectively.

[0038] The ring 31 is sleeved on the fin tube 4, enabling the ring 31 to effectively drive the spray nozzles 32 to move along the fin tube 4.

[0039] The nozzles of the spray nozzles 32 face the fin tube 4. Through the spray nozzles 32, the fin tube 4 can be impacted with high pressure and large water volume, which can not only effectively exchange heat with the fin tube 4 but also effectively wash the debris on the fin tube 4, keeping the fin tube 4 in efficient heat exchange.

[0040] Further optimized solution. Lead screws 3 are symmetrically arranged inside the housing 1. The lead screws 3 are arranged along the axial direction of the fin tube 4 and are located between the atomizing spray nozzles 17 and the fin tube 4, so that the lead screws 3 will not affect the atomizing spray nozzles 17 spraying water mist on the fin tube 4.

[0041] To ensure that the lead screws 3 do not affect the atomizing spray nozzles 32 spraying water mist, the lead screws 3 are arranged between two adjacent branch pipes.

[0042] Further optimized solution. The ring 31 is threadedly connected to the lead screws 3. The end of the lead screws 3 extending outside the housing 1 is drivingly connected to a motor 34. The motor 34 is fixedly connected to the outer wall of the housing 1 and is electrically connected to the controller. The motor 34 drives the lead screws 3 to rotate. The lead screws 3 drive the ring 31 to move along the fin tube 4, and the ring 31 drives the spray nozzles 32 to move along the fin tube 4, enabling the water sprayed by the spray nozzles 32 to effectively contact the fin tube 4 for heat exchange. At the same time, the water sprayed by the spray nozzles 32 can also wash the surface of the fin tube 4, effectively keeping the surface of the fin tube 4 clean and maintaining the efficient heat exchange of the fin tube 4.

[0043] Working process: When the flow rate monitored by the flowmeter 42 is above 85% of the full-load state of the fin tube 4 and the temperature monitored by the first temperature detector is higher than the threshold value, the controller opens the first solenoid valve 14, closes the second solenoid valve 16 and the third solenoid valve 22, and controls the water pump 11 and the drain pump 5 to operate at full power.

[0044] When the flow rate monitored by the flowmeter 42 is above 85% of the full-load state of the finned tube 4 and the temperature monitored by the first temperature detector is lower than the threshold value, the first solenoid valve 14 is opened through the controller, the second solenoid valve 16 and the third solenoid valve 22 are closed, and the water supply pump 11 and the drainage pump 5 are controlled to operate at corresponding powers.

[0045] When the flow rate monitored by the flowmeter 42 is between 50% and 85% of the full-load state of the finned tube 4, the data of the first temperature detector is not required. Only the second solenoid valve 16 is opened through the controller, the first solenoid valve 14 and the third solenoid valve 22 are closed, and the water supply pump 11 and the drainage pump 5 are controlled to operate at a power that satisfies the water mist pressure and flow rate of all the atomizing nozzles 17.

[0046] When the flow rate monitored by the flowmeter 42 is below 50% of the full-load state of the finned tube 4 and the temperature monitored by the first temperature detector is lower than the threshold value, only the second solenoid valve 16 is opened through the controller, the first solenoid valve 14 and the third solenoid valve 22 are closed, and the water supply pump 11 and the drainage pump 5 are controlled to operate at the lowest power.

[0047] When the water supply pump 11 and the drainage pump 5 are operating at full power, the temperature monitored by the first temperature detector is higher than the threshold value and the temperature monitored by the second temperature detector is lower than the threshold value, indicating that there are a large number of stains on the surface of the finned tube 4, which affects the heat exchange efficiency of the finned tube 4. At this time, the third solenoid valve 22 is opened through the controller, the first solenoid valve 14 and the second solenoid valve 16 are closed, and the water supply pump 11 and the drainage pump 5 are controlled to operate at full power. The motor 34 is started, the motor 34 drives the lead screw 3 to rotate, the lead screw 3 drives the ring 31 to move along the finned tube 4, and the ring 31 drives the nozzle 32 to move along the finned tube 4, so that the water sprayed by the nozzle 32 can wash the finned tube 4 with high pressure and large flow rate, and at the same time, the sprayed water can effectively contact the finned tube 4 for heat exchange. At the same time, the surface of the finned tube 4 is washed by the water sprayed by the nozzle 32, and the stains are washed off from the finned tube 4, which can not only effectively keep the surface of the finned tube 4 clean, but also effectively improve the heat exchange efficiency of the finned tube 4.

[0048] When the ring 31 is not working, the ring 31 is close to the water inlet end or the water outlet end in the housing 1, so that the ring 31 does not affect the heat exchange work.
