Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning equipment, and specifically relates to an energy-saving plate-tube indirect evaporative cooling water chiller. Background Art

[0002] The energy-saving plate-tube indirect evaporative cooling water chiller is an energy-saving and environment-friendly device that uses the principle of evaporative cooling for refrigeration. Its basic principle is: by utilizing the characteristic that water absorbs heat when evaporating, heat is transferred from the working fluid (such as water) to the air through a plate-tube heat exchanger, so that the air temperature is reduced, while the temperature of the working fluid rises, and finally the heat is discharged from the system through the condensation process. Since air and water do not directly contact during the heat exchange process, the humidity of the air remains unchanged, achieving the effect of constant-humidity cooling.

[0003] The patent document that has been publicly disclosed is CN207350632U, which provides an energy-saving plate-tube indirect evaporative cooling water chiller, "including: a housing, on which a primary air inlet and an air outlet are respectively arranged, and inside the housing, a filtering device, an indirect evaporative cooling section, and a packing tower section are sequentially arranged according to the air flow direction; the packing tower section is located in the center of the housing, and a group of indirect evaporative cooling sections are symmetrically arranged on both sides of the packing tower section. The packing tower section specifically includes packing b, and on top of packing b, packing a, a water distributor a, a water baffle, and an axial flow fan are sequentially arranged, and at the bottom of packing b, a cold water tank is arranged, and the cold water tank and the water distributor a are connected by a return pipe", which can effectively achieve evaporation heat exchange treatment.

[0004] However, in the actual evaporation refrigeration process, the plate-tube indirect evaporation cooling core body remains stationary, and each group of ventilation heat exchange plates is arranged in an array. The actual heat exchange ability with water is poor, and the heat exchange part only conducts heat exchange treatment on the side and top surfaces. The actual heat exchange treatment effect is average, and the packing therein is fixedly filled inside the device. Affected by corrosion, it needs to be replaced regularly. However, the actual replacement operation is inconvenient, and the ability of the static packing to increase the contact area between air and water and improve the heat exchange efficiency is limited, resulting in poor comprehensive heat exchange effect and unsatisfactory use effect.

[0012] Preferably, the spraying assembly includes a water distribution sleeve and an inlet pipe. The water distribution sleeve is fixedly connected inside the evaporation tank.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. By utilizing the power of the power assembly, the plate-type indirect evaporation cooling assemblies on both sides are driven to rotate simultaneously. During the actual refrigeration process, by using the continuously rotating plate-type indirect evaporation cooling assemblies and the surrounding heat exchange plates, during the rotation process, each group of heat exchange plates can fully contact the water sprayed above, avoiding the situation of uneven local heat exchange of the heat exchange plates with hot gas inside, greatly improving the actual heat exchange effect. And in cooperation with the surrounding heat exchange plates, by using the filling parts between adjacent heat exchange plates, the spraying water area near the heat exchange plates is further expanded, further increasing the water film area and improving the heat exchange effect, and the use effect is good.

[0018] 2. The present invention utilizes an elastic filling component sleeved between the heat exchange plates distributed in a surrounding manner. By using the V-shaped plates in the elastic filling component and the elastic material effect of the V-shaped plates, elastic tension fixation is maintained between two adjacent heat exchange plates. During rotation, the protruding front end of the V-shaped plate contacts and presses against the arc-shaped inner wall of the evaporation tank, thereby pushing the V-shaped plate to slide between two adjacent groups of heat exchange plates. At the same time, the V-shaped plate itself undergoes adaptive extrusion. On the one hand, the moving effect is used to frictionally slide the outer side of the heat exchange plate to clean the surface dirt. On the other hand, the two sides of the V-shaped plate are compressed and brought closer, driving the installed filling part to move and be extruded, and elastically resetting when the elastic filling component rotates to the upper side, realizing the extrusion jitter of the filling part and the reciprocating friction of the heat exchange plate, achieving self-cleaning and self-jitter of the micro-motion effect, and further improving the heat exchange effect.

[0019] 3. The present invention utilizes the elastic effect of the elastic filling component, which has an extrusion effect when rotating to the arc-shaped inner wall of the evaporation tank. In cooperation with the outlet opened at the bottom of the evaporation tank and the corresponding socketed sealing cover, when the elastic filling component rotates to the corresponding position of the sealing cover, by opening the sealing cover, the elastically restored elastic filling component directly makes the outer end of the elastic filling component automatically push into the bottom outlet, and the removal operation can be completed directly by pulling from the bottom. The actual operation is simple and the material replacement is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 to 9 shown, the embodiment of the present invention provides an energy-saving plate-tube indirect evaporative cooling water chiller, including an air guide frame 1, a spraying component 7, a water tank 6, and an axial flow fan 2 fixed on the top of the air guide frame 1. Evaporator boxes 3 are fixedly arranged on both sides of the air guide frame 1. A plate-tube indirect evaporative cooling component 4 is rotatably installed inside the evaporator box 3. The air outlet end of the plate-tube indirect evaporative cooling component 4 is communicated with the air guide frame 1. A power component 5 is fixedly arranged inside the air guide frame 1. The two air inlet ends of the power component 5 are fixedly connected and communicated with the plate-tube indirect evaporative cooling components 4 on both sides. The power component 5 controls the rotation of the plate-tube indirect evaporative cooling component 4.

[0032] The plate-tube indirect evaporative cooling component 4 includes a rotating tube 41, a heat exchange plate 42, an air guide frame 43, an intermediate plug 44, a first hole 45, and a second hole 46. The heat exchange plates 42 are fixedly connected around the outer surface of the rotating tube 41 and communicated with the rotating tube 41.

[0033] An elastic filling component 9 is elastically sleeved between adjacent heat exchange plates 42.

[0034] Embodiment 1: During use, start the axial flow fan 2 at the top of the air guide frame 1. As the air inside the air guide frame 1 is sucked out, the internal air pressure decreases, and the hot air volume in the outside ambient air is inhaled into the rotating tube 41 of the plate-type indirect evaporative cooling assembly 4 and enters the interior of the heat exchange plate 42 through the first hole 45. The incoming hot air fills the interior of the slow heat exchange plate 42 along the air guide frame 43, is inhaled through the second hole 46 to the other side of the intermediate plug 44 in the rotating tube 41, and is inhaled into the air guide frame 1 through the rotating tube 41. At the same time, start the water pump 63 in the water tank 6, so that the water pump 63 sucks the circulating water from the box body 61 and transports it to the spraying assembly 7, so that the sprayed water is sprayed onto the surface of the plate-type indirect evaporative cooling assembly 4 and adheres to the elastic filling assembly 9. The gaps of the filling parts 93 in the elastic filling assembly 9 are filled with water. During the rotation process, each heat exchange plate 42 performs rapid heat exchange, and during the rotation process, the elastic filling assembly 9 located between two adjacent groups of heat exchange plates 42 contacts and is squeezed on the arc-shaped inner wall of the evaporation box 3, so that the V-shaped plate 91 is compressed and slides along the gap between the adjacent heat exchange plates 42. On the one hand, the sliding V-shaped plate 91 slides along the inner wall to clean the dirt on the surface of the heat exchange plate 42, and the symmetrically distributed filling parts 93 approach and squeeze, and when rotating to the upper part, the V-shaped plate 91 elastically resets, forming sliding and self-vibration between the heat exchange plates 42; when replacement is needed, rotate the corresponding elastic filling assembly 9 to the lower part and above the sealing cover 11. At this time, the elastic filling assembly 9 is elastically compressed, rotate the locking ring in the sealing cover 11, and open the sealing cover 11. The elastic filling assembly 9 elastically resets and automatically slides out from the bottom to complete the removal. As it rotates gradually, the automatic discharging of each group of elastic filling assemblies 9 is completed in sequence for replacement.

[0035] First, through the power action of the power assembly 5, drive the plate-type indirect evaporative cooling assemblies 4 on both sides to rotate simultaneously. During the actual refrigeration process, by using the continuously rotating plate-type indirect evaporative cooling assemblies 4 and the surrounding-designed heat exchange plates 42, during the rotation process, each heat exchange plate 42 can be in full contact with the water sprayed above, avoiding the situation of uneven local heat exchange of the heat exchange plate 42 with hot air inside, greatly improving the actual heat exchange effect. And in cooperation with the surrounding-distributed heat exchange plates 42, by using the filling parts 93 between the adjacent heat exchange plates 42, the spraying water area near the heat exchange plates 42 is further expanded, further increasing the water film area and improving the heat exchange effect, with good use effect.

[0036] In addition, by sleeving an elastic filling component 9 between the heat exchange plates 42 distributed in a surrounding manner, using the V-shaped plate 91 in the elastic filling component 9, and utilizing the elastic material effect of the V-shaped plate 91, elastic tension fixation is maintained between two adjacent heat exchange plates 42. During rotation, the protruding front end of the V-shaped plate 91 contacts and presses against the arc-shaped inner wall of the evaporation tank 3, thereby pushing the V-shaped plate 91 to slide between two adjacent groups of heat exchange plates 42, and at the same time causing the V-shaped plate 91 to be adaptively squeezed itself. On the one hand, the outer side of the heat exchange plate 42 is frictionally slid using the moving effect to clean the surface dirt. On the other hand, the two sides of the V-shaped plate 91 are compressed and closed, driving the installed filling part 93 to move and be squeezed, and elastically resetting when the elastic filling component 9 rotates to the upper side, realizing the squeezing and jittering of the filling part 93 and the reciprocating friction of the heat exchange plate 42, achieving self-cleaning and self-jittering of the micro-movement effect, and further improving the heat exchange effect.

[0037] On the other hand, by utilizing the elastic effect of the elastic filling component 9, there is an extrusion effect when rotating to the arc-shaped inner wall of the evaporation tank 3. In cooperation with the outlet opened at the bottom of the evaporation tank 3 and the corresponding socketed sealing cover 11, when the elastic filling component 9 rotates to the corresponding position of the sealing cover 11, by opening the sealing cover 11, using the elastically restored elastic filling component 9, the outer end of the elastic filling component 9 is directly pushed to the bottom outlet automatically, and the extraction operation can be completed directly by pulling from the bottom. The actual operation is simple and the refueling is convenient.

[0038] Among them, the rotating tube 41 is rotatably sleeved inside the evaporation tank 3. Both ends of the rotating tube 41 penetrate through the evaporation tank 3, and one end is provided with a filtering part, and the other end is fixedly connected to the power component 5. An internal cavity is provided inside the heat exchange plate 42. The air guide frame 43 is in a "V" shape and is fixed in the internal cavity. The middle plug 44 is fixedly sleeved inside the rotating tube 41. The number of the first holes 45 and the second holes 46 is the same and corresponds to the heat exchange plates 42 one by one. The first holes 45 and the second holes 46 are located on both sides of the middle plug 44. Both the first holes 45 and the second holes 46 are communicated with the internal cavity inside the heat exchange plate 42. One end of the air guide frame 43 is provided with a notch, and the other end of the air guide frame 43 is fixedly connected to the outer side surface of the rotating tube 41 and is located between the first holes 45 and the second holes 46.

[0039] By using the plate-tube indirect evaporation cooling component 4 to achieve internal hot gas filling and exchange heat with external sprayed water, the middle plug 44 isolates the first holes 45 and the second holes 46, ensuring that the gas is fully filled into the heat exchange plate 42, and the design of the air guide frame 43 further guides the movement of the hot gas in the heat exchange plate 42, improving the filling effect, avoiding the rapid output of the hot gas, and increasing the heat exchange time.

[0040] Among them, the power component 5 includes an intermediate pipe 51, a first gear 52, a bypass port 53, and a rotating motor 54. The rotating motor 54 is fixed inside the air guide frame 1. The intermediate pipe 51 is fixedly connected between the rotating pipes 41 on both sides. The bypass port 53 is opened on the outer surface of the intermediate pipe 51. The first gear 52 is fixedly sleeved on the outer surface of the intermediate pipe 51. The rotating motor 54 drives the engaged first gear 52 to rotate through a second gear on the output shaft.

[0041] The power component 5 rotates the plate-tube indirect evaporative cooling component 4, and at the same time rotates the plate-tube indirect evaporative cooling components 4 on both sides, and cooperates with the bypass port 53 to export gas into the air guide frame 1. An insulating sleeve is provided outside the rotating motor 54, and the bottom of the insulating sleeve penetrates through the air guide frame 1 through a bottom pipe to avoid the influence of the heat of the rotating motor 54.

[0042] Among them, the water tank 6 includes a box body 61, a return pipe 62, and a water pump 63. The box body 61 is located below the evaporation box 3. One end of the return pipe 62 is fixedly sleeved on the top of the box body 61, and the other end is fixedly connected to the bottom of the evaporation box 3 and communicates with the inside of the evaporation box 3. The water pump 63 is fixedly installed on the top of the box body 61. The suction end of the water pump 63 is fixedly sleeved in the box body 61, and the pump-out end of the water pump 63 is fixedly connected and communicated with the spraying component 7.

[0043] The box body 61 in the water tank 6 is mainly a circulating water tank. The water pump 63 pumps water from the box body 61 and inputs it into the spraying component 7 to spray downward on the rotating heat exchange plate 42, and the remaining unevaporated water after spraying flows back to the box body 61 through the return pipe 62.

[0044] Among them, the spraying component 7 includes a water distribution sleeve 71 and an inlet pipe 72. The water distribution sleeve 71 is fixedly connected inside the evaporation box 3. Nozzles are also fixedly provided at the bottom of the water distribution sleeve 71. The nozzles are located above the plate-tube indirect evaporative cooling component 4. One end of the inlet pipe 72 is fixedly connected to the pump-out end of the water pump 63, and the other end is fixedly connected to the water distribution sleeve 71. The water pump 63 inputs water into the water distribution sleeve 71 through the inlet pipe 72. An air outlet 8 is opened at the top of the evaporation box 3.

[0045] The spraying component 7 is used for spraying, providing refined liquid beads, and forming a water film in the filling part 93 to increase the heat exchange area and improve the heat absorption and evaporation effect. The air outlet 8 is used to export the evaporated water vapor, and cooperate with an external condensation mechanism for condensation and re-divert it back to the box body 61.

[0046] Among them, the elastic filling component 9 includes a V-shaped plate 91, a support plate 92 and a filling part 93. The V-shaped plate 91 is an elastic plate, and the V-shaped plate 91 is movably sleeved between adjacent heat exchange plates 42. The side surface of the V-shaped plate 91 is provided with a friction surface, and an assembly groove is formed on the side surface. The support plate 92 is fixedly connected in the assembly groove. The filling parts 93 are symmetrically arranged inside the V-shaped plate 91 and fixedly connected to the support plate 92. There is a gap between the symmetrically distributed filling parts 93. During the rotation of the V-shaped plate 91, it intermittently presses and contacts the inner wall of the evaporation tank 3, and the V-shaped plate 91 is elastically compressed and slides along between adjacent heat exchange plates 42.

[0047] The elastic filling component 9 utilizes the compressed elastic effect and is alternately distributed in the heat exchange plates 42. On the one hand, it realizes the formation of a water film at a short distance and improves the evaporation effect. On the other hand, relative swinging and sliding are generated under repeated elastic actions. Under the swinging effect, the water film in the filling part 93 continuously bursts, and the heat absorption effect is improved by expanding the bursting area. Moreover, during the sliding, the heat exchange plates 42 are frictionally cleaned to remove scale, and by using the effect of elastic tension and clamping between the heat exchange plates 42, it can also be conveniently removed and replaced when the sealing cover 11 is opened at the bottom, and the damaged filling part 93 can be conveniently replaced.

[0048] Among them, a positioning ring 10 is fixedly arranged inside the evaporation tank 3. The positioning rings 10 are symmetrically distributed at both ends of the plate-type indirect evaporation cooling component 4. The bottom surface of the inner surface of the evaporation tank 3 is an arc surface, and a sealing cover 11 is movably installed at the bottom of the evaporation tank 3.

[0049] By using the positioning ring 10 to position both sides of the plate-type indirect evaporation cooling component 4 and simultaneously restricting the axial offset of the elastic filling component 9, when the sealing cover 11 is opened, the replacement process of the elastic filling component 9 can be realized from the bottom.

[0050] Among them, the sealing cover 11 includes a socket plug 111 and an arc plate 112. The socket plug 111 is movably sleeved at the bottom of the evaporation tank 3. The arc plate 112 is fixedly connected to the bottom of the socket plug 111. The sealing cover 11 further includes a fixing column and a locking ring. The fixing column is fixedly connected to the bottom of the evaporation tank 3 and is movably sleeved with the arc plate 112. The locking ring is threadedly sleeved on the outer surface of the fixing column and clamps and fixes the arc plate 112 upward.

[0051] By using the threaded reduction of the locking ring, the disassembly and assembly are convenient and the fixing is stable.

[0052] Working principle and usage process of the present invention: During use, start the axial flow fan 2 at the top of the air guide frame 1. As the air inside the air guide frame 1 is sucked out, the internal air pressure decreases, and the hot air volume in the outside ambient air is inhaled into the rotating tube 41 of the plate-type indirect evaporative cooling component 4 and enters the interior of the heat exchange plate 42 through the first hole 45. The incoming hot air fills the interior of the slow heat exchange plate 42 along the air guide frame 43, is inhaled through the second hole 46 to the other side of the intermediate plug 44 in the rotating tube 41, and is inhaled into the air guide frame 1 through the rotating tube 41. At the same time, start the water pump 63 in the water tank 6, so that the water pump 63 sucks the circulating water from the box body 61 and transports it to the spraying component 7, so that the sprayed water is sprayed onto the surface of the plate-type indirect evaporative cooling component 4 and adheres to the elastic filling component 9. The gaps of the filling part 93 in the elastic filling component 9 are filled with water. During the rotation process, each heat exchange plate 42 conducts rapid heat exchange, and during the rotation, the elastic filling component 9 located between adjacent two groups of heat exchange plates 42 contacts and is squeezed on the arc-shaped inner wall of the evaporation box 3, so that the V-shaped plate 91 is compressed and slides along the gap between adjacent heat exchange plates 42. On the one hand, the sliding V-shaped plate 91 slides along the inner wall to clean the dirt on the surface of the heat exchange plate 42, and the symmetrically distributed filling parts 93 approach and squeeze, and when rotated to the upper part, the V-shaped plate 91 elastically resets, forming sliding and its own jitter between the heat exchange plates 42; when replacement is needed, make the corresponding elastic filling component 9 rotate to the lower part and be located above the sealing cover 11. At this time, the elastic filling component 9 is elastically compressed, rotate the locking ring in the sealing cover 11, and open the sealing cover 11. The elastic filling component 9 elastically resets and automatically slides out from the bottom to complete the removal. As it rotates gradually, the automatic discharging of each group of elastic filling components 9 is completed in sequence, and replacement can be carried out.

The scope of the present invention is defined by the appended claims and their equivalents.
