Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold water machine, and particularly relates to an energy-saving industrial cold water machine. BACKGROUND

[0002] The cold water machine is a water cooling equipment capable of providing constant temperature, constant flow and constant pressure, and the industrial cold water machine is generally composed of a condenser, an expansion valve, an evaporator and a compressor, wherein the refrigerant liquid in the cold water machine is evaporated by absorbing heat from the liquid to be cooled through the evaporator, so as to achieve the effect of cooling the liquid.

[0003] At present, in the use of the cold water machine, in the long-term hot water circulation process, the impurities in the water are easy to adhere to the outer wall of the heat exchange pipe, forming a dirt layer that hinders heat transfer, not only reducing the already low heat exchange efficiency, but also forcing the equipment to consume more energy to maintain the cooling demand. At the same time, in the heat exchange link between the refrigerant liquid and the heat exchange pipe in the evaporator, the refrigerant liquid cannot fully and uniformly contact the heat exchange pipe, and part of the refrigerant liquid directly settles at the bottom of the heat exchange pipe without contacting the heat exchange pipe, which not only affects the heat exchange efficiency, but also causes waste of the refrigerant liquid. SUMMARY

[0006] To solve the above technical problems, the application provides the following technical scheme: an energy-saving industrial water chiller, comprising a fixed part, wherein the fixed part further comprises an evaporator unit, a centrifugal compressor, a condenser, a control part and an oil separation part; the evaporator unit is fixedly installed on the fixed part, the centrifugal compressor is fixedly installed on the top of the evaporator unit, the condenser is fixedly installed on the other end of the centrifugal compressor, the condenser is fixedly connected with the fixed part, the control part is fixedly installed on the top of the condenser, and the oil separation part is fixedly installed on the top of the condenser; the evaporator unit comprises an evaporator assembly fixedly installed on the fixed part, an adjusting assembly fixedly installed on the evaporator unit, a first fixed plate fixedly installed on the inner wall of the evaporator assembly, a second fixed plate fixedly installed on the inner wall of the evaporator assembly, a heat exchange pipe fixedly installed on the second fixed plate, and the heat exchange pipe is slidably connected with the adjusting assembly and the first fixed plate.

[0007] As a preferred scheme of the energy-saving industrial water chiller, the evaporator assembly comprises an evaporator body fixedly installed on the fixed part and a rotating groove arranged on the inner wall of the evaporator body.

[0008] As a preferred scheme of the energy-saving industrial water chiller, the adjusting assembly comprises a push rod fixedly installed on the evaporator body, a moving piece fixedly installed on the output end of the push rod, a rotating piece rotatably installed on the outer wall of the moving piece, and a sliding block fixedly installed on the outer wall of the rotating piece, and the sliding block slides in the rotating groove.

[0009] As a preferred scheme of the energy-saving industrial water chiller, the rotating piece is fixedly installed with a sealing ring on one side, the moving piece is fixedly installed with a scraping ring on the inner wall, and the scraping ring is slidably connected with the heat exchange pipe.

[0010] As a preferred scheme of the energy-saving industrial water chiller, the rotating piece is fixedly installed with a connecting piece, the connecting piece is fixedly installed with a turnover piece, and the inner wall of the turnover piece is fixedly installed with a guide block.

[0011] As a preferred scheme of the energy-saving industrial water chiller, the spraying assembly comprises a spraying piece fixedly installed on the evaporator body, a guide piece fixedly installed on the output end of the spraying piece, a first rotating spray pipe rotatably installed on the inner wall of the guide piece, and a second rotating spray pipe rotatably installed in the first rotating spray pipe, and the second rotating spray pipe is rotatably connected with the moving piece.

[0012] As a preferred embodiment of the energy-saving industrial chiller of the present invention, a spiral guide plate is fixedly installed on the inner wall of the rotating nozzle, and multiple sets of nozzles are provided on the inner wall of the rotating nozzle.

[0013] As a preferred embodiment of the energy-saving industrial chiller of the present invention, a conical pressure member is fixedly installed on the inner wall of the rotating nozzle, and the conical pressure member is rotatably connected to the guide member.

[0014] As a preferred embodiment of the energy-saving industrial chiller of the present invention, a spiral guide plate is fixedly installed on the inner wall of the rotating nozzle two, and a nozzle two is provided on the inner wall of the rotating nozzle two.

[0015] As a preferred embodiment of the energy-saving industrial chiller of the present invention, the partition component includes a cooling water inlet fixedly installed on the evaporator body, a cooling water outlet fixedly installed on the evaporator body, and a partition plate fixedly installed on the inner wall of the evaporator body, wherein the partition plate is fixedly connected to the fixed plate.

[0016] The beneficial effects of this invention are as follows: This invention enhances the contact area between the condensate and the heat exchange tubes through the matrix rotating spray design of the spray assembly, fundamentally improving the heat exchange efficiency of both. At the same time, with the cooperation of the adjustment assembly and the evaporator assembly, the condensate that falls to the bottom of the evaporator assembly is rotated and sprayed back onto the heat exchange tubes, solving the waste problem caused by the traditional refrigerant settling at the bottom and not being able to contact the heat exchange tubes, thus maximizing the utilization of the condensate's heat exchange potential.

This effectively prevents impurities from affecting the heat exchange efficiency between the heat exchange tube and the condensate, reduces energy consumption increases caused by scaling, and extends the maintenance cycle of the heat exchange tube. Furthermore, by flexibly adjusting the component's movement range within the evaporator assembly, the heat exchange space can be dynamically switched. When the heat exchange load is low, the adjusting component moves to the middle, using only half of the heat exchange space to achieve energy-saving operation. When the heat exchange load is high, the adjusting component moves to one end, fully opening the heat exchange space to meet the high-efficiency cooling requirements, achieving automatic adaptation of heat exchange power and enhancing energy-saving effects. After the condensate is vaporized through heat exchange and absorption, it is returned to the condenser by the centrifugal compressor for re-liquefaction, and then circulated back to the evaporator assembly through the spray component, forming a highly efficient closed-loop cycle to ensure continuous and stable cooling.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Example 1, referring to Figure 1 - Figure 3 The first embodiment of the present invention provides an energy-saving industrial chiller, which includes: a fixing part 1, an evaporator unit 2, a centrifugal compressor 3, a condenser 4, a control part 5, and an oil-liquid separator 6; An evaporator unit 2 is fixedly installed on the fixed part 1 for evaporation and heat exchange. A centrifugal compressor 3 is fixedly installed through the top of the evaporator unit 2 for reabsorbing the condensate after evaporation. A condenser 4 is fixedly installed through the other end of the centrifugal compressor 3 for recondensing the evaporated condensate back into liquid. The condenser 4 is fixedly connected to the fixed part 1. A control part 5 is fixedly installed on the top of the condenser 4 for controlling the overall equipment. An oil-liquid separator 6 is fixedly installed on the top of the condenser 4 for separating the condensate from the liquid.

[0034] The evaporator unit 2 includes an evaporator assembly 21 fixedly mounted on a fixed part 1 for heat exchange, an adjustment assembly 22 fixedly mounted on the evaporator assembly 21 for adjusting heat exchange efficiency, a first fixed plate 23 fixedly mounted on the inner wall of the evaporator assembly 21 for sealing, a second fixed plate 25 fixedly mounted on the inner wall of the evaporator assembly 21 for density adjustment in conjunction with the first fixed plate 23, and a heat exchange tube 24 fixedly mounted on the second fixed plate 25 for contact heat exchange with the condensate. The other end of the heat exchange tube 24 is connected to the first fixed plate 23, and the heat exchange tube 24 is slidably connected to the adjustment assembly 22 for circulating cooling water. Furthermore, a drain port 29 is fixedly installed at the bottom of the evaporator assembly 21 for discharging impurities. A dividing assembly 28 is fixedly installed through one side of the evaporator assembly 21 for transporting and dividing cooling water. A spray assembly 26 is fixedly installed on the inner wall of the evaporator assembly 21, and the output end of the spray assembly 26 is connected to the fixed plate 25 and the adjusting assembly 22. At the same time, the input end of the spray assembly 26 is fixedly connected through the condenser 4 for spraying condensate inside the evaporator assembly 21.

[0035] During operation, cooling water first enters the heat exchange tube 24 through the dividing assembly 28, while condensate from the condenser 4 enters the evaporator assembly 21 through the spray assembly 26. The matrix spraying of the spray assembly 26 brings the condensate into contact with the outer wall of the heat exchange tube 24, initiating heat exchange. During this process, some condensate fails to contact the heat exchange tube 24 and falls to its bottom. The adjusting assembly 22 then rotates along the evaporator assembly 21 towards the fixed plate 25, simultaneously re-spraying the condensate that fell to the bottom of the heat exchange tube 24 back onto its outer wall. This effectively prevents condensate waste. The adjusting assembly 22 also recovers residual condensate. While the condensate is being discharged, it can move along the outer wall of the heat exchange tube 24, scraping away impurities accumulated on the tube wall in real time and pushing them to the drain port 29 for centralized discharge, reducing energy consumption increases caused by scaling. Furthermore, by flexibly adjusting the movement range of the adjusting component 22 within the evaporator component 21, the heat exchange space can be dynamically switched. When the heat exchange load is low, the adjusting component 22 moves to the middle of the evaporator component 21, using only half of the heat exchange space to achieve energy-saving operation. When the heat exchange load is high, the adjusting component 22 moves to one end of the evaporator component 21, fully opening the heat exchange space to meet the high-efficiency cooling requirements, achieving automatic adaptation of heat exchange power and enhancing the energy-saving effect. At the same time, after the condensate is vaporized by heat exchange and heat absorption, it is returned to the condenser 4 by the centrifugal compressor 3 for re-liquefaction, and then circulated back into the evaporator component 21 through the spray component 26, forming a high-efficiency closed-loop cycle to ensure continuous and stable cooling.

[0036] Example 2, refer to Figure 1 - Figure 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the dividing component 28 includes a cooling water inlet 281 fixedly installed on the evaporator body 211 for the entry of cooling water, a cooling water outlet 282 fixedly installed on the evaporator body 211 for the output of cooling water, and a dividing plate 283 fixedly installed on the inner wall of the evaporator body 211. The dividing plate 283 is fixedly connected to the second fixing plate 25 and is used to divide the input and output of cooling water.

[0037] Compared to Embodiment 1, the spray assembly 26 further includes a spray element 261 fixedly installed on the evaporator body 211 for conveying condensate, a guide element 262 fixedly installed on the output end of the spray element 261 for pressurizing the condensate, a rotating nozzle 263 fixedly and rotatably installed on the inner wall of the guide element 262 for guiding the condensate, and a rotating nozzle 267 rotatably installed inside the rotating nozzle 263, wherein the rotating nozzle 267 is rotatably connected to the moving element 222 for extending and guiding the condensate.

[0038] Furthermore, a spiral guide plate 265 is fixedly installed on the inner wall of the rotary nozzle 263 to guide the flow of condensate. Multiple sets of nozzles 266 are provided on the inner wall of the rotary nozzle 263 to spray condensate. A conical pressurizing component 264 is fixedly installed on the inner wall of the rotary nozzle 263, and the conical pressurizing component 264 is rotatably connected to the guide component 262 to pressurize the condensate.

[0039] Furthermore, a spiral guide plate 268 is fixedly installed on the inner wall of the rotary nozzle 267 to guide the flow of condensate, and a nozzle 269 is provided on the inner wall of the rotary nozzle 267 to spray out condensate.

[0040] During operation, after cooling water enters the evaporator body 211 through cooling water inlet 281, it enters the heat exchange tube 24 under the separation and cooperation of fixed plate 25 and partition plate 283. Simultaneously, the condenser 4 delivers the internal condensate to the spray element 261, which in turn delivers the condensate to the guide element 262. The condensate entering the guide element 262, under the limiting and squeezing of the conical pressurizing element 264, impacts a large amount of the condensate into the spiral guide plate 265 inside the rotating nozzle 263. The condensate impacts the spiral guide plate 265 and is simultaneously sprayed out in a matrix pattern through nozzles 266, causing the rotating nozzle 263 to begin rotating and spraying inside the guide element 262. The condensate also impacts the spiral guide plate 268 in the second rotating nozzle 267, and with the inclined setting of the second nozzle 269, the condensate begins to spray out, causing the second rotating nozzle 267 to rotate in the first rotating nozzle 263. Because the spraying directions of the first nozzle 266 and the second nozzle 269 are set differently, different and opposite forces are generated when the condensate is sprayed out, so that the second rotating nozzle 267 and the first rotating nozzle 263 rotate and spray in opposite directions, thereby increasing the spraying range and spraying angle of the condensate, increasing the contact area between the condensate and the heat exchange tube 24, and improving the heat exchange efficiency between the condensate and the heat exchange tube 24. Then, the cooled water that has been cooled is transported from the other end of the heat exchange tube 24 to the cooling water outlet 282 and discharged.

[0041] The remaining structure is the same as that in Example 1.

[0042] Example 3, referring to Figure 1 - Figure 12 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the evaporator assembly 21 includes an evaporator body 211 fixedly mounted on the fixing part 1 for heat exchange evaporation, and a rotating groove 212 provided on the inner wall of the evaporator body 211 for cooperating with the adjustment assembly 22 to rotate.

[0043] Compared to Embodiment 2, the adjustment assembly 22 further includes a push rod 221 that passes through and is fixedly installed on the evaporator body 211 for pushing; a movable member 222 fixedly installed at the output end of the push rod 221 for restricting the heat exchange tube 24; a rotating member 224 rotatably installed on the outer wall of the movable member 222 for rotating; and a sliding block 226 fixedly installed on the outer wall of the rotating member 224, and the sliding block 226 slides inside the rotating groove 212 to drive the rotating member 224 to rotate.

[0044] Furthermore, a sealing ring 225 is fixedly installed on one side of the rotating part 224 for sealing purposes, and a scraper ring 223 is fixedly installed on the inner wall of the moving part 222. The scraper ring 223 is slidably connected to the heat exchange tube 24 for scraping impurities off the outer wall of the heat exchange tube 24.

[0045] Furthermore, a connector 227 is fixedly installed on the rotating part 224 for fixing purposes, and a flipping part 228 is fixedly installed on the connector 227 for collecting the condensate that falls to the bottom again. A guide block 229 is fixedly installed on the inner wall of the flipping part 228 for guiding the flow of the collected condensate.

[0046] During operation, when the spray assembly 26 sprays condensate and contacts the heat exchange tube 24 for heat exchange, some condensate does not contact the heat exchange tube 24 and falls to the bottom of the heat exchange tube 24. At this time, the push rod 221 extends, moving the moving part 222 and the rotating part 224 on the outer wall of the moving part 222 together inside the evaporator body 211. While the rotating part 224 moves, the sliding block 226 on the outer wall of the rotating part 224 moves inside the rotating groove 212. Guided and restricted by the rotating groove 212 and the sliding block 226, the rotating part 224 begins to rotate along the outer wall of the moving part 222 while moving with the moving part 222. The connecting part 227 and the flipping part 228 also rotate together with the rotating part 224. During the rotation of the flipping part 228, the condensate that has fallen to the bottom of the heat exchange tube 24 can be re-treated. The condensate is collected and then re-sprayed onto the outer wall of the heat exchange tube 24 by the rotation of the rotating component 224, enhancing the heat exchange efficiency between the condensate and the heat exchange tube 24. Simultaneously, the moving component 222 moves along the outer wall of the heat exchange tube 24. The scraping ring 223 inside the moving component 222 scrapes and cleans the outer wall of the heat exchange tube 24, preventing impurities from adhering to the outer wall and affecting heat exchange. When the heat exchange load is low, the push rod 221 drives the moving component 222 to move to the middle position of the evaporator body 211, using only half of the heat exchange space for energy-saving operation. When the heat exchange load is high, the moving component 222 moves back to one end of the evaporator body 211, fully opening the heat exchange space to meet high-efficiency cooling requirements, achieving automatic heat exchange power adaptation, enhancing energy-saving effects, increasing heat exchange efficiency, and avoiding condensate waste.

[0047] The remaining structure is the same as that in Example 2.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
