Description

Technical Field

[0001] The invention relates to the technical field of heat exchange devices, and in particular to a high-efficiency heat exchanger. Background Art

[0002] Heat exchanger, also known as heat exchanger, is a device that transfers part of the heat of hot fluid to cold fluid. In chemical, petroleum, power, food and many other industrial production, heat exchanger plays a vital role, such as heater, cooler, condenser, evaporator and reboiler, etc., to achieve heat transfer and recovery.

[0003] In the process of heat exchange by cooling water in the existing heat exchanger, when the gas enters the flow channel, due to the low temperature of the channel and the temperature difference, the moisture contained in the incoming air will condense in the channel. The device has a poor effect on cleaning the condensed water. The condensed water will reduce the cooling effect of the channel in the heat exchanger and affect the humidity of the flowing gas in the channel.

[0004] For example, in an indirect evaporative cooler provided by authorization announcement No. CN119063514B, after condensed water adheres to the heat exchange plate, the humidity of the air discharged from the primary air outlet will increase, and the humidity in the dry channel is monitored by a humidity monitoring module. When the humidity reaches a preset value, the driving module drives the linkage module and the condensed water elimination module to move, thereby scraping off the condensed water adhered to the heat exchange plate, and guiding the scraped and remaining condensed water into the receiving box through the flow groove through the inclined plate member, and discharging the collected water through the drainage pipe fitting, thereby preventing the condensed water adhered to the heat exchange plate from affecting the cooling effect of the dry channel in the heat exchanger.

[0005] It has major disadvantages: the rear end scraper plate and the front end scraper plate are in an inclined state during the descent process, and the front end scraper plate is located at the bottom and at the primary air outlet. During the descent process, the scraped condensed water will gather at the end of the front end scraper plate away from the rear end scraper plate, and because there is always gas flowing between the primary air inlet and the primary air outlet, the condensed water gathered at one end of the front end scraper plate is easily blown off during the flow of gas, resulting in scraping and collection failure. Summary of the invention

[0006] The embodiment of the present application solves the problem in the prior art that the rear end scraper plate and the front end scraper plate are in an inclined state during the descent process, and the front end scraper plate is located at the bottom and at the primary air outlet. During the descent process, the scraped condensed water will gather at the end of the front end scraper plate away from the rear end scraper plate, and because there is always gas flowing between the primary air inlet and the primary air outlet, the gas is likely to blow off the condensed water gathered at one end of the front end scraper plate during the flow, resulting in scraping and collection failure, thereby realizing the V-shape of the lower side of the scraper, which can more conveniently collect more condensed water. During the descent of the scraper, the scraper is close to the side where the wind enters, and the condensed water is blown to the lower tip of the scraper, and dripped by the gravity of the condensed water itself; the scraper itself can intercept the side away from the wind entrance to avoid the condensed water being blown out and splashing on all sides due to the action of wind, so that it can drip by its own gravity or the drainage of the scraper, and gather in the middle of the lower end of the scraper and drip, thereby improving the collection efficiency and ensuring the cooling effect of the gas in the air outlet.

[0017] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: First, the lower side of the scraper is changed into a V-shape, which can make it easier to collect more condensed water. When the scraper descends, the scraper is close to the side where the wind enters, and the condensed water is blown to the lower tip of the scraper, and drips by the gravity of the condensed water itself; the scraper itself can intercept the side away from the wind to prevent the condensed water from being blown out and splashing on all sides due to the action of wind, so that it can drip by its own gravity or the drainage of the scraper, and gather in the middle of the lower end of the scraper to drip, thereby improving the collection efficiency and ensuring the cooling effect of the gas in the tuyere; Secondly, air bags are fixed on both sides of the scraper to prevent condensed water from reattaching. When the scraper rises, the air bags retract and do not directly contact the inner wall of the air outlet, effectively preventing the scraped condensed water from reattaching to the inner wall of the air outlet due to the movement of the scraper, and preventing the upper side from scraping off the condensed water during the scraper's rise, thereby improving the cleaning effect; the air bag can fit tightly against the inner wall of the air outlet in the expanded state, thereby improving the thoroughness and uniformity of wiping; the air bag will generate a certain vibration during the expansion and retraction process, shaking off the condensed water remaining on the surface of the air bag and the lower side of the scraper, thereby preventing the condensed water from dripping onto the inner wall of the air outlet due to the effect of wind force during the rising process, thereby ensuring the cooling effect on the gas in the air outlet; Third, the effect of shedding condensed water is enhanced. When the electromagnet is energized to absorb the iron block, the airbag is deformed. Then the electromagnet is de-energized, and the iron block is reset under the elastic force of the airbag. Vibration is generated in this process, which effectively shakes off the condensed water accumulated under the scraper, on the lower side of the airbag and on the inner wall of the tuyere, improving the cleaning and collection effect, thereby further ensuring the cooling effect of the gas in the tuyere; the airbag hits the inner wall of the tuyere during the vibration process, causing the cooling water sprayed in the water inlet to vibrate as well. This vibration breaks the thermal boundary layer between the cooling water and the inner wall, enhancing the heat transfer efficiency; thereby improving the cooling efficiency of the entire device and the heat exchange effect; when the scraper moves to the lowest end, the electromagnet is intermittently energized to cause the airbag to deform and vibrate, further improving the vibration effect and shaking off the condensed water on the surface; Fourthly, through the intermittent rapid contraction and expansion of different positions of the cavity in the airbag, the gas in the inflatable cavity formed by the airbag, the wiping bag and the air outlet is ejected, and the gas is ejected downward from the inside. The gas acts on the accumulated condensed water, and the condensed water is blown downward quickly, thereby improving the collection and cleaning effect of the condensed water; when the wiping bag contracts intermittently, the blown gas can dry the inner wall of the air outlet; and in the process of descending and rising, the remaining water stains are wiped by the fluff on the surface of the wiping bag, thereby further improving the cleaning effect; in the inflatable cavity formed by the airbag, the wiping bag and the air outlet, the gas is continuously injected, which can dry the remaining water stains inside, further ensuring the cooling effect of the gas in the air outlet.

[0023] Embodiment 1: Figure 1-Figure 8As shown, the present application provides a high-efficiency heat exchanger, including a cooling component 100 and a power component 300; The cooling assembly 100 is used to exchange heat with air, and the cooling assembly 100 includes a heat exchange shell 110 and an air outlet 111; The heat exchange shell 110 has an air port 111 on one side, and the air port 111 is used for air intake, and the air port 111 runs through the heat exchange shell 110; The power assembly 300 is disposed on one side of the heat exchange shell 110; Also included is a cleaning assembly 200, wherein the cleaning assembly 200 includes a scraper 210; The scraper 210 is disposed on the power assembly 300. The scraper 210 is located in the air outlet 111. The scraper 210 is in the shape of a triangular prism. The cross section of the scraper 210 is an isosceles triangle. The intersection of the two waists of the isosceles triangle of the cross section of the scraper 210 faces downward. In the initial state, the upper side of the scraper 210 is in close contact with the upper side of the air outlet 111; The lower side of the air outlet 111 passes through the heat exchange shell 110, and both sides of the scraper 210 extend out of the air outlet 111; There are multiple air outlets 111, which are evenly spaced, and the number of scrapers 210 is consistent with the number of air outlets 111, and they correspond one to one; The cooling assembly 100 further includes a water inlet 112, a water tank 120, a fan 130, a fixing frame 140, a water spray frame 150, a bottom plate 160, a limiting groove 161, a drain port 162, a humidity sensor 170 and a water pump 180; The upper side of the heat exchange shell 110 is provided with a water inlet 112, and the water inlet 112 passes through the heat exchange shell 110. The number of the water inlets 112 is consistent with the number of intervals between the plurality of air vents 111, and they correspond one to one. The water inlet 112 is used to flow cooling water to cool the side wall of the air outlet 111; The upper side of the heat exchange shell 110 is fixed with a fixing frame 140, and the lower side of the fixing frame 140 is provided with a water spraying frame 150. The number of the water spraying frames 150 is consistent with the number of the water inlets 112, and they correspond one to one. The output end of the water spraying frame 150 faces the water inlet 112. The water pump 180 is fixed on the fixing frame 140, the output end of the water pump 180 is connected to the water spray frame 150, and the input end of the water pump 180 is connected to the water source; When the water pump 180 is working, water is sprayed from the water spray rack 150 toward the water inlet 112 to cool the side of the air outlet 111; The upper side of the bottom plate 160 is fixed to the lower side of the heat exchange shell 110. The bottom plate 160 has a limiting groove 161. The lower ends of the air outlet 111 and the water inlet 112 are both connected to the upper end opening of the limiting groove 161. The lower openings of the air outlet 111 and the water inlet 112 are completely located above the limiting groove 161; The limiting groove 161 is in the shape of a triangular prism, and the cross section of the limiting groove 161 is an isosceles triangle, and the intersection of the two sides of the isosceles triangle of the cross section of the limiting groove 161 faces downward; After the scraper 210 descends, it is completely fitted with the limiting groove 161; A drain port 162 is provided under the limiting groove 161, a water tank 120 is fixed on the lower side of the bottom plate 160, a lower end of the drain port 162 is communicated with the water tank 120, and a drain valve is provided on one side of the water tank 120; After the scraper 210 scrapes off the condensed water, the condensed water slides into the limiting groove 161 and flows into the water tank 120 through the drain port 162 for storage, and the cooling water flowing in the water inlet 112 slides into the limiting groove 161 and flows into the water tank 120 through the drain port 162 for storage; The fan 130 is fixed on the water tank 120 and is located on one side of the heat exchange shell 110. The fan 130 is located on one side of the air outlet 111. The humidity sensor 170 is fixed on the output end of the fan 130. The humidity sensor 170 is used to detect the humidity of the output wind; The power assembly 300 is located between the fan 130 and the heat exchange shell 110; The power assembly 300 includes a mounting plate 1 310, an electric slide 320, a slider 330, a connecting plate 340 and a mounting plate 2 350; The first mounting plate 310 is fixed to a side of the heat exchange shell 110 close to the fan 130, and the second mounting plate 350 is fixed to a side of the bottom plate 160 close to the fan 130; The mounting plate 1 310 is located above the air outlet 111; There are two electric slides 320 and two sliders 330, respectively, and they correspond one to one. The two electric slides 320 are symmetrically fixed between the first mounting plate 310 and the second mounting plate 350, the slider 330 is slidably arranged on the electric slide 320, and the two ends of the connecting plate 340 are respectively fixed on the sides of the two sliders 330 close to each other; One end of the scraper 210 is fixed to the lower side of the connecting plate 340; When the electric slide 320 is working, it drives the scraper 210 to rise or fall in the air outlet 111; The length direction of the electric slide 320 is perpendicular to the ground, and the sliding direction of the slider 330 is the sliding direction of the electric slide 320; The humidity sensor 170 , the electric slide 320 and the fan 130 are all existing technologies and will not be described in detail here.

[0024] During use, the fan 130 is started, and the external air is sucked into the air outlet 111 and discharged. In this process, heat exchange is performed through the side wall of the air outlet 111; during the start-up of the fan 130, the water spray rack 150 works, and the cooling water is sprayed into the water inlet 112 to cool the side wall of the air outlet 111. The cooling water flows into the limit groove 161 and flows into the water tank 120 through the drain port 162 for storage. The stored water can be used again after being cooled and discharged through the drain valve on one side. Due to the effect of temperature difference, a large amount of heat will accumulate in the air outlet 111 after long-term use. Condensed water, after the humidity sensor 170 detects the increase in the humidity of the output air, the fan 130 is turned off, and the electric slide 320 is started, driving the scraper 210 to move from top to bottom, and the condensed water on the side wall of the air outlet 111 is scraped off. A large amount of condensed water is gathered at the lower end of the middle part through the inclined bottom side of the scraper 210, and drips into the limiting groove 161. The condensed water can drip from top to bottom in the limiting groove 161 and enter the water tank 120 for storage; the scraper 210 moved to the bottom side is moved and reset to the upper end after scraping once, which is convenient for the next side to scrape the condensed water, and then the fan 130 is started again to exchange heat with the air.

[0025] Compared with the prior art, the lower side of the scraper 210 is made into a V-shape, which can more conveniently collect more condensed water. During the descent of the scraper 210, the scraper 210 is close to the side where the wind enters, and the condensed water is blown to the lower tip of the scraper 210, and drips by the gravity of the condensed water itself; the scraper 210 itself can intercept the side away from the wind entrance to prevent the condensed water from being blown out and splashing on all sides due to the action of the wind, so that it can drip through its own gravity or the drainage of the scraper 210, and gather in the middle of the lower end of the scraper 210 and drip, thereby improving the collection efficiency and ensuring the cooling effect on the gas in the air outlet 111.

[0026] Embodiment 2: When the embodiment 1 is in use, the condensed water in the air outlet 111 is scraped off by the up and down movement of the scraper 210. However, during use, when the side of the scraper 210 is rising, the condensed water remaining under the scraper 210 will re-attach to the inner wall of the air outlet 111, resulting in a poor cleaning effect; and because the air outlet 111 is in a connected state and is always ventilated, the condensed water will re-attach to the upper part after the scraper 210 scrapes it, and will re-attach to the upper end during the rising process of the scraper 210. Based on this, the solution of the embodiment 1 is improved, such as Figure 9-13 As shown: The cleaning assembly 200 further includes a fitting member, an air pump member 230 and a communication port 213; The number of the laminating parts is consistent with the number of the scrapers 210 and corresponds one to one; A gap is left between the scraper 210 and the inner wall of the air outlet 111; The fitting member includes an airbag 220, and the airbag 220 has two airbags 220, and the airbag 220 is V-shaped. The two airbags 220 are symmetrically fixed on both sides of the scraper 210 near the inner wall of the air outlet 111; The airbag 220 has air outlets 111 extending from both ends of the V-shaped opening; The scraper 210 is hollow inside, the air pump member 230 is fixed on the top side of the scraper 210, the air pump member 230 includes an expansion air pump, and the output end of the expansion air pump in the air pump member 230 is connected to the inside of the airbag 220; The upper side of the scraper 210 is provided with a communication port 213, and the communication port 213 is connected to the cavity of the scraper 210; The input end of the expansion air pump in the air pump member 230 is in communication with the internal cavity of the scraper 210; When the expansion air pump in the air pump member 230 is working, the airbag 220 is expanded or retracted.

[0027] When in use, when the scraper 210 is used to clean the inner wall of the air outlet 111, the airbag 220 expands and fits against the inner wall of the air outlet 111. When the scraper 210 is descending, the condensed water on the inner wall of the air outlet 111 is scraped off by the airbag 220. After the scraper 210 finishes scraping, the airbag 220 continues to expand and contract, generating vibration to shake off the condensed water on the surface; when the scraper 210 needs to rise, the airbag 220 deflates and does not contact the inner wall of the air outlet 111.

[0028] The airbags 220 are fixed on both sides of the scraper 210 to prevent the condensed water from reattaching. During the rising process of the scraper 210, the airbags 220 retract and do not directly contact the inner wall of the air outlet 111, which effectively prevents the scraped condensed water from reattaching to the inner wall of the air outlet 111 due to the movement of the scraper 210, and prevents the condensed water from being scraped off the upper side during the rising process of the scraper 210, thereby improving the cleaning effect; the airbags 220 can fit tightly against the inner wall of the air outlet 111 in the expanded state, thereby improving the thoroughness and uniformity of wiping; during the expansion and retraction process of the airbags 220, a certain vibration will be generated, which will shake off the condensed water remaining on the surface of the airbag 220 and the lower side of the scraper 210, thereby preventing the condensed water from dripping again on the inner wall of the air outlet 111 due to the action of wind force during the rising process, thereby ensuring the cooling effect on the gas in the air outlet 111.

[0029] Embodiment 3: When the embodiment 2 is in use, the scraper 210 moves up and down, and the airbag 220 expands and fits, so as to clean the condensed water on the inner wall of the tuyere 111. However, during use, the cleaning effect of the condensed water by the airbag 220 alone is poor. Based on this, the embodiment 2 is improved, such as Figure 14-17 As shown: The cleaning assembly 200 further includes a mounting groove 211, an electromagnet 240 and a deformable member; The scraper 210 has mounting grooves 211 symmetrically disposed on both sides of the inner wall close to the air outlet 111. The mounting grooves 211 are V-shaped and are located in the V-shaped opening of the airbag 220. The number of the electromagnets 240 is consistent with the sum of the number of the mounting grooves 211 on the sides of the scrapers 210, and they correspond one to one; The electromagnet 240 has the same shape as the mounting groove 211, and the electromagnet 240 is fixed in the mounting groove 211; The number of the deformable parts is consistent with the sum of the number of the airbags 220 and corresponds one to one; The deformable member includes an iron block 250, and one deformable block includes a plurality of iron blocks 250; A plurality of iron blocks 250 are evenly spaced and fixed in the air bag 220, and the plurality of iron blocks 250 are distributed in a V shape; After the airbag 220 is inflated, the iron block 250 does not contact the inner wall of the air port 111, and the iron block 250 is located on the upper side of the airbag 220; When the electromagnet 240 is powered on, the iron block 250 is attracted to deform the airbag 220 . When the electromagnet 240 is powered off, the iron block 250 is reset by the elastic force of the airbag 220 , deforming the airbag 220 and hitting the inner wall of the air outlet 111 .

[0030] After the airbag 220 on the side of the scraper 210 expands, it is closely attached to the inner wall of the air outlet 111. During the process of the scraper 210 descending, the airbag 220 will be deformed upward due to the friction between the airbag 220 and the inner wall of the air outlet 111. At this time, the electromagnet 240 is energized to attract the iron block 250. When the electromagnet 240 attracts the iron block 250, the airbag 220 is deformed. After that, the electromagnet 240 is de-energized, and the iron block 250 is reset by the elastic force of the airbag 220, and the airbag 220 is deformed as a whole. The scraper 210 generates vibrations to shake off the condensed water accumulated on the surface below the scraper 210 and the airbag 220, causing the accumulated condensed water to drip or provide power to drain it gradually downward; and in the process of vibration, it can hit the inner wall of the air outlet 111, so that the cooling water sprayed in the water inlet 112 can vibrate, breaking the thermal boundary layer between the cooling water and the inner wall; when the scraper 210 moves to the lowermost end, the electromagnet 240 is intermittently energized to cause the airbag 220 to deform and vibrate, thereby shaking off the condensed water on the surface.

[0031] To enhance the effect of shedding condensed water, when the electromagnet 240 is energized to adsorb the iron block 250, the airbag 220 is deformed, and then the electromagnet 240 is de-energized, and the iron block 250 is reset under the elastic force of the airbag 220. Vibration is generated in this process, which effectively shakes off the condensed water accumulated under the scraper 210, on the lower side of the airbag 220 and on the inner wall of the air outlet 111, thereby improving the cleaning and collection effect, thereby further ensuring the cooling effect of the gas in the air outlet 111; the airbag 220 hits the inner wall of the air outlet 111 during the vibration process, so that the cooling water sprayed in the water inlet 112 also vibrates, and this vibration breaks the thermal boundary layer between the cooling water and the inner wall, thereby enhancing the heat transfer efficiency; thereby improving the cooling efficiency of the entire device and the heat exchange effect; when the scraper 210 moves to the lowermost end, the electromagnet 240 is intermittently energized to cause the airbag 220 to deform and vibrate, thereby further improving the vibration effect and shaking off the condensed water on the surface.

[0032] Embodiment 4: Embodiment 3 is to cut off the power after the electromagnet 240 adsorbs the iron block 250, so that the airbag 220 vibrates, thereby cleaning the condensed water accumulated under the scraper 210, on the lower side of the airbag 220 and on the inner wall of the air outlet 111; the device can also be further improved to improve the collection and cleaning effect of the condensed water, based on which the solution of embodiment 3 is improved, such as Figure 18-19 As shown: The cleaning assembly 200 further includes an air inlet 212, a separation membrane 221, a wiping bag 260, an expansion pump 270 and an air blowing pump 280; There are multiple separation membranes 221, which are evenly spaced and fixed in the airbag 220. The multiple separation membranes 221 separate the cavity of the airbag 220 into multiple cavities that are not connected to each other. The number of the wiping bags 260 is consistent with the number of the air bags 220 and corresponds one to one. The wiping bags 260 are located in the V-shaped opening of the air bags 220 and are fixed on the scraper 210. The two ends of the wiping bag 260 in the length direction are fixed on the air bag 220, and the surface of the wiping bag 260 is covered with fluff; The number of the inflation air pumps in the air pump member 230 is consistent with the number of the cavities separated by the separation membrane 221 in the airbag 220, and they correspond one to one; The expansion pump 270 and the blowing pump 280 are both fixed to the top side of the expansion pump 270; The output end of the expansion pump 270 is communicated with the interior of the wiping bag 260; The expansion pump 270 works to expand the wiping bag 260, and then the fluff on the surface of the wiping bag 260 absorbs the water stains remaining on the inner wall of the air outlet 111; After the airbag 220 and the wiping bag 260 expand and come into contact with the inner wall of the air outlet 111, an inflatable cavity is formed among the airbag 220, the wiping bag 260 and the air outlet 111. The scraper 210 has air inlets 212 on both sides, and the air inlets 212 are located in the air-filled cavity formed by the airbag 220, the wiping bag 260, and the air outlet 111. The air-filled cavity formed by the airbag 220, the wiping bag 260, and the air outlet 111 is located in the air outlet 111. The output end of the air pump 280 is connected to the air inlets 212 on both sides of the scraper 210; Input ends of the expansion pump 270 and the air blowing pump 280 are both connected to the inner cavity of the scraper 210 .

[0033] During use, the expansion air pump in the air pump member 230 works together with the expansion pump 270 to expand the airbag 220 and the wiping bag 260 together and press against the inner wall of the air outlet 111. During the descent of the scraper 210, the airbag 220 presses against the condensed water and presses against the condensed water on the inner wall of the air outlet 111, and the remaining water stains are absorbed by the fluff on the surface of the wiping bag 260. During the descent of the scraper 210, the blowing pump 280 works to blow air into the inflatable cavity formed by the airbag 220, the wiping bag 260 and the air outlet 111. During the blowing process, the cavities at different positions in the airbag 220 contract intermittently and rapidly. During the expansion and contraction process, gas is ejected downward from the inside, and the gas acts on the accumulated condensed water, blowing the condensed water downward quickly; and during the intermittent contraction of the wiping bag 260, the blown gas can dry the inner wall of the air outlet 111; during the rising process of the scraper 210, the airbag 220 retracts, and the wiping bag 260 does not retract, and the inner wall of the air outlet 111 is wiped again by the wiping bag 260; when the scraper 210 reaches the top, the wiping bag 260 continues to expand and retract, and the fluff on the surface of the wiping bag 260 is dried by the air flowing in the air outlet 111 and the air flow driven by its own expansion and contraction.

[0034] Through the intermittent rapid contraction and expansion of different positions of the cavity in the airbag 220, the gas in the inflatable cavity formed among the airbag 220, the wiping bag 260 and the air outlet 111 is ejected, and the gas is ejected downward from the inside. The gas acts on the accumulated condensed water, and the condensed water is blown downward quickly, thereby improving the collection and cleaning effect of the condensed water; when the wiping bag 260 contracts intermittently, the blown gas can dry the inner wall of the air outlet 111; and in the process of descending and ascending, the remaining water stains are wiped by the fluff on the surface of the wiping bag 260, thereby further improving the cleaning effect; in the inflatable cavity formed among the airbag 220, the wiping bag 260 and the air outlet 111, the gas is continuously injected, which can dry the remaining water stains inside, further ensuring the cooling effect of the gas in the air outlet 111.
