Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic ribbon production, and particularly to an air-cooling mechanism for channel-divided cooling of copper wires of photovoltaic ribbons. Background Art

[0002] Photovoltaic ribbons are an important component of photovoltaic modules. They are mainly composed of a copper substrate and a surface coating, and are used to lead out the electrical energy converted on the silicon wafers by light energy and transport it to electrical equipment. The production of photovoltaic ribbons can be divided into multiple processes, each with its specific functions and quality control requirements. The main processes include: material preparation, cleaning treatment, tin plating process, rough hot pressing, stretching and quenching, annealing treatment, quality inspection, surface anti-oxidation treatment, packaging and storage.

[0003] The main material of photovoltaic ribbons is copper, which is a material that expands and contracts with heat. At high temperatures, the copper wires will expand; after cooling, the copper wires will shrink back to their original size. Therefore, during the above production process of photovoltaic ribbons, it is necessary to strictly control the temperature of the copper wires of photovoltaic ribbons, especially during the annealing and tin plating processes. Excessive or too low temperature will affect the performance of the ribbons.

[0004] After searching the prior art for "a multi-channel step-by-step wire drawing production line for copper wires", the publication number is "CN112246895B". This device winds the copper wires around the outside of the first transmission wheel and the second transmission wheel and then places them into the wire drawing die, ensuring that each wire drawing die can draw wires normally at the same time and without interference from each other to ensure the smooth progress of each wire drawing. This device is provided with a fan to cool the copper wires being drawn, but when the moisture in the air comes into contact with the metal surface, condensate droplets will be generated on the cooled metal surface, affecting the metal quality. Summary of the Invention

[0005] Based on this, in view of the problem that when the moisture in the air comes into contact with the metal surface, condensate droplets will be generated on the cooled metal surface, affecting the copper wires of photovoltaic ribbons, it is necessary to provide an air-cooling mechanism for channel-divided cooling of copper wires of photovoltaic ribbons.

[0006] An air-cooling mechanism for channel-divided cooling of copper wires of photovoltaic ribbons includes: a low-temperature liquid tank, the lower end of the low-temperature liquid tank is fixedly connected with a vortex tube; a temperature reduction mechanism, the temperature reduction mechanism is installed inside the low-temperature liquid tank, the surface of the temperature reduction mechanism extends to the outside of the low-temperature liquid tank, and the surface of the temperature reduction mechanism is communicated with the air outlet end of the vortex tube; wherein, the temperature reduction mechanism includes a low-temperature component arranged inside the low-temperature liquid tank, the low-temperature component is installed inside the low-temperature liquid tank, the surface of the low-temperature component extends to the outside of the low-temperature liquid tank, a dehumidification component is arranged on the surface of the low-temperature component, the dehumidification component extends below the low-temperature liquid tank, and a moisture removal component is arranged at the lower end of the low-temperature component, and the moisture removal component is installed at one end of the low-temperature liquid tank.

[0007] In one embodiment, the dehumidification component includes an air inlet duct fixedly connected to one side of the low-temperature liquid tank. One end of the air inlet duct penetrates into the interior of the low-temperature liquid tank and communicates with the surface of the low-temperature component. The other end of the air inlet duct extends below the low-temperature liquid tank. A fixing sleeve is fixedly connected to the surface of the air inlet duct, and a spiral tube is embedded in the surface of the fixing sleeve. The upper end of the spiral tube is fixedly connected to a low-temperature outlet pipe communicating with the spiral tube, and the other end of the low-temperature outlet pipe communicates with the cold air end of the vortex tube. A high-pressure air inlet pipe is provided on one side of the vortex tube, which can introduce gas into the vortex tube. Then, part of the gas is introduced into the low-temperature outlet pipe through the cold air end of the vortex tube. The temperature value of the cold air end can be appropriately adjusted according to the processing material and the processing season environment. It is best to keep the temperature at four degrees Celsius, plus or minus three degrees Celsius. As long as the cooling effect of the photovoltaic solder strip copper wire is ensured, the specific temperature value can be appropriately adjusted according to the actual situation. The cold air inside the low-temperature outlet pipe is introduced into the spiral tube, and the temperature of the air inlet duct is reduced through the spiral tube, so that the moisture carried by the gas to be introduced into the air inlet duct can be quickly condensed. Then, the outside gas is introduced into the low-temperature component through the air inlet duct to air-cool the split copper wire, and at the same time, the moisture during the air-cooling process can be reduced, ensuring that during the later stranding process of the solder strip, the generation of condensed liquid on the surface of the photovoltaic solder strip copper wire is reduced.

[0008] In one embodiment, the low-temperature component includes a cooling middle pipe fixedly connected to the inner wall of the low-temperature liquid tank. Both ends of the cooling middle pipe penetrate to the outside of the low-temperature liquid tank. Temperature guiding connectors are fixedly connected to both sides of the cooling middle pipe, and the other ends of the temperature guiding connectors are fixedly connected to the inner wall of the low-temperature liquid tank. A low-temperature sleeve is sleeved on the surface of the cooling middle pipe, and the surface of the low-temperature sleeve is embedded in the interior of the temperature guiding connector. The low-temperature sleeve communicates with the end of the dehumidification component. A temperature guiding liquid is stored inside the low-temperature liquid tank. By the cooling middle pipe being inside the low-temperature liquid tank, the cooling middle pipe is maintained at a low temperature, assisting the dehumidification component to have a good air-cooling effect on the copper wire. By setting the low-temperature sleeve sleeved on the surface of the cooling middle pipe, the effect of the temperature guiding liquid assisting in cooling the cooling middle pipe is improved. And while the temperature guiding connector cooperates with the low-temperature liquid tank to enhance the positioning effect on the cooling middle pipe, it can also assist in positioning the low-temperature sleeve. At the same time, the temperature guiding connector can conduct the low temperature on the surface of the low-temperature sleeve to the cooling middle pipe, so that the cooling middle pipe maintains a relatively low temperature. The air inlet duct communicates with the cooling middle pipe, and when the cooling gas is introduced into the cooling middle pipe through the air inlet duct, since the cooling middle pipe maintains a low-temperature state, the air-cooling effect of the low-temperature gas on the photovoltaic solder strip copper wire is ensured.

[0009] In one embodiment, the moisture-removing component includes two connecting frames fixedly connected to the end of the low-temperature liquid tank. The other ends of the two connecting frames are fixedly connected with an air chamber. The surface of the air chamber is communicated with a high-temperature air outlet pipe, and the high-temperature air outlet pipe is communicated with the hot gas end of the vortex tube. The inner wall of the air chamber is rotatably connected with a sprocket wheel, and the upper end of the air chamber extends above the sprocket wheel. The temperature value at the hot gas end can be appropriately adjusted according to the processing material and the processing season environment. The temperature is preferably maintained at 23 degrees Celsius, plus or minus 3 degrees Celsius. It is only necessary to ensure that the copper wire of the photovoltaic solder ribbon has a cooling effect. The specific temperature value is appropriately adjusted according to the actual situation. The copper wire of the photovoltaic solder ribbon in the cooling middle pipe is led out and passes through the sprocket wheel. At this time, since the sprocket wheel is installed inside the air chamber, and gas is introduced into the air chamber through the high-temperature air outlet pipe, the copper wire of the photovoltaic solder ribbon is cooled and the air flow is guided to the sprocket wheel groove through the air chamber through the high-temperature air outlet pipe, so that the temperature of the copper wire of the photovoltaic solder ribbon is closer to normal temperature, ensuring good metal properties.

[0010] In one embodiment, the lower end of the spiral tube is communicated with a middle low-temperature tube. The surface of the middle low-temperature tube close to the spiral tube penetrates into the interior of the air inlet channel. The other end of the middle low-temperature tube extends above the spiral tube and is fixedly connected with a low-temperature outlet tube. The other end of the low-temperature outlet tube penetrates into the interior of the low-temperature liquid tank. Through the setting of the middle low-temperature tube, the middle low-temperature tube is located on the central axis of the air inlet channel, and the condensation effect of the gas inside the air inlet channel is improved through the middle low-temperature tube, and the low-temperature gas is guided into the cooling middle tube through the low-temperature outlet tube.

[0011] In one embodiment, a heat-insulating sleeve is fixedly connected to the surface of the fixed sleeve. The inner wall of the heat-insulating sleeve is in contact with the surface of the spiral tube. A plurality of spiral heat-conducting plates are fixedly connected to the inner wall of the fixed sleeve. The end of the spiral heat-conducting plate away from the fixed sleeve is fixedly connected to the surface of the middle low-temperature tube. The plurality of spiral heat-conducting plates are annularly distributed along the inner wall of the fixed sleeve. The surface of the middle low-temperature tube is fixedly connected to the surface of the spiral heat-conducting plate. The spiral heat-conducting plate is arranged in a spiral shape. When the gas enters the interior of the air inlet channel, it comes into full contact with the surface of the spiral heat-conducting plate in a spiral shape. And since the fixed sleeve can conduct the low temperature of the spiral tube to the spiral heat-conducting plate, and the overall temperature of the spiral heat-conducting plate is kept balanced through the middle low-temperature tube, the moisture in the cooling gas can be better condensed when the gas entering the interior of the air inlet channel passes through the spiral heat-conducting plate, reducing the occurrence of the situation where condensed liquid is generated on the surface of the copper wire during cooling.

[0012] In one embodiment, two first colloidal spiral plates are fixedly connected to the inner wall of the cooling middle pipe near the end. The first colloidal spiral plates are spiral-shaped, and the two first colloidal spiral plates are arranged mirror-symmetrically. One end of one first colloidal spiral plate is fixedly connected to one side of the other first colloidal spiral plate, and the second colloidal spiral plate is fixedly connected to the inner wall of the cooling middle pipe. Uniform intake slots are formed in the inner edge of the second colloidal spiral plate. The gas is introduced into the cooling middle pipe through the intake duct and discharged from both ends of the cooling middle pipe. At this time, due to the cooperation of the first colloidal spiral plate and the second colloidal spiral plate, the airflow is blocked, increasing the gas flow rate and improving the air-cooling effect on the copper wire. At the same time, the materials of the first colloidal spiral plate and the second colloidal spiral plate can be colloidal components, which can reduce the vibration of the copper wire driven by the airflow. The first colloidal spiral plate and the second colloidal spiral plate can relieve the amplitude of the copper wire while contacting the copper wire. Moreover, the first colloidal spiral plate is spirally arranged, which can extend the contact path of part of the gas with the copper wire and improve the air-cooling effect. In addition, the first colloidal spiral plate and the second colloidal spiral plate cooperate with the inner wall of the cooling middle pipe to form an air duct. Through the arranged intake slots, part of the low-temperature airflow can be assisted to be discharged in time after heat exchange, so that the subsequent low-temperature gas can be replenished in time to ensure the cooling effect of the gas on the copper wire.

[0013] In one embodiment, the other end of the low-temperature sleeve is communicated with a cooling coil. The other end of the cooling coil is fixedly connected to an injection pipe, and the other end of the injection pipe penetrates into the interior of the intake duct. The cooling coil is arranged in an S shape. The low-temperature sleeve guides the low-temperature gas into the cooling coil. Since the shape of the cooling coil improves the cooling effect on the liquid in the low-temperature liquid tank, it can assist in ensuring the relatively low-temperature effect of the cooling middle pipe, reducing the excessive heat loss generated when the gas in the intake duct enters the cooling middle pipe, and assisting the dehumidification component to air-cool the photovoltaic solder ribbon copper wire.

[0014] In one embodiment, two fixed seats are fixedly connected between the two connecting frames, and a sponge cone sleeve is fixedly connected to the inner wall of the fixed seat. The sponge cone sleeve is conical. The arranged sponge cone sleeve can assist in wiping and adsorbing the coolant drops on the surface of the copper wire, reducing the residual liquid on the surface of the photovoltaic solder ribbon copper wire and reducing the corrosion of the metal material.

[0015] In one embodiment, a gas guide cavity is formed inside the gas chamber, and two groups of flow guide plates are fixedly connected to the inner wall of the gas guide cavity. The two groups of flow guide plates are arranged staggeredly. The high-temperature gas outlet pipe introduces the gas into the gas chamber. At this time, the gas blows towards the flow guide plates. Under the guidance of the two groups of staggeredly distributed flow guide plates, the airflow can converge towards the copper wire to ensure the blowing effect on the surface of the copper wire.

[0016] The above-mentioned air-cooling mechanism for channel-by-channel cooling of copper wires in photovoltaic soldering tapes can cool the copper wires through the provided cooling mechanism. Among them, the provided dehumidification component can condense the moisture inside the air flow while guiding the air flow for cooling the copper wires, reducing the surface humidity of the photovoltaic soldering tape copper wires. At the same time, the dehumidification component cooperating with the low-temperature component can keep the surrounding temperature relatively low during the copper wire cooling operation, reducing the heat loss of the low-temperature gas cooling operation, achieving the purpose of cooling the photovoltaic soldering tape copper wires while reducing the condensation of moisture in the gas on the surface of the photovoltaic soldering tape copper wires, and reducing the corrosion of the photovoltaic soldering tape copper wires, thus ensuring the quality after metal processing;

[0017] In this device, through the provided low-temperature component, under the action of the low-temperature component, the photovoltaic soldering tape copper wires are cooled to a relatively low temperature environment. And with the cooperation of the first colloid spiral plate and the second colloid spiral plate, the local gas flow rate in the middle cooling tube increases, improving the cooling effect on the photovoltaic soldering tape copper wires. And with the cooperation of the temperature conduction connecting piece, it ensures the function of maintaining a relatively low-temperature cooling environment in the middle cooling tube, ensuring the quality after metal processing;

[0018] This device uses the provided moisture-removing component to assist in wiping the possible remaining condensate droplets on the surface of the cooled photovoltaic soldering tape copper wires. At the same time, the air chamber cooperating with the grooved wheel can assist in drying the wet area on the surface of the copper wires, reducing the surface wetness of the photovoltaic soldering tape copper wires and preventing the occurrence of corrosion to the metal, ensuring the quality after metal processing.

[0039] The following combination with Figures 1-12An air-cooling mechanism for channel-divided cooling of copper wires in a photovoltaic solder tape according to the present invention includes: a low-temperature liquid tank 100, and an eddy current tube 200 is fixedly connected to the lower end of the low-temperature liquid tank 100; a temperature reduction mechanism 300, the temperature reduction mechanism 300 is installed inside the low-temperature liquid tank 100, the surface of the temperature reduction mechanism 300 extends to the outside of the low-temperature liquid tank 100, and the surface of the temperature reduction mechanism 300 is communicated with the air outlet end of the eddy current tube 200; wherein, the temperature reduction mechanism 300 includes a low-temperature component 320 arranged inside the low-temperature liquid tank 100, the low-temperature component 320 is installed inside the low-temperature liquid tank 100, the surface of the low-temperature component 320 extends to the outside of the low-temperature liquid tank 100, a dehumidification component 310 is arranged on the surface of the low-temperature component 320, the dehumidification component 310 extends below the low-temperature liquid tank 100, a moisture-removing component 330 is arranged at the lower end of the low-temperature component 320, and the moisture-removing component 330 is installed at one end of the low-temperature liquid tank 100;

[0040] As Figures 1-8 shown, the dehumidification component 310 includes an air inlet duct 311 fixedly connected to one side of the low-temperature liquid tank 100, one end of the air inlet duct 311 penetrates into the low-temperature liquid tank 100 and is communicated with the surface of the low-temperature component 320, the other end of the air inlet duct 311 extends below the low-temperature liquid tank 100, a fixing sleeve 314 is fixedly connected to the surface of the air inlet duct 311, a spiral tube 313 is embedded in the surface of the fixing sleeve 314, a low-temperature air outlet pipe 312 communicated with the spiral tube 313 is fixedly connected to the upper end of the spiral tube 313, the other end of the low-temperature air outlet pipe 312 is communicated with the cold air end of the eddy current tube 200, a middle low-temperature tube 317 is communicated with the lower end of the spiral tube 313, the surface of the middle low-temperature tube 317 close to the spiral tube 313 penetrates into the air inlet duct 311, the other end of the middle low-temperature tube 317 extends above the spiral tube 313 and is fixedly connected to a low-temperature lead-out pipe 318, the other end of the low-temperature lead-out pipe 318 penetrates into the low-temperature liquid tank 100, a heat-insulating sleeve 316 is fixedly connected to the surface of the fixing sleeve 314, the inner wall of the heat-insulating sleeve 316 is in contact with the surface of the spiral tube 313, a plurality of spiral heat-conducting plates 315 are fixedly connected to the inner wall of the fixing sleeve 314, one end of the spiral heat-conducting plates 315 away from the fixing sleeve 314 is fixedly connected to the surface of the middle low-temperature tube 317, and the plurality of spiral heat-conducting plates 315 are annularly distributed along the inner wall of the fixing sleeve 314;

[0041] One side of the vortex tube 200 is provided with a high-pressure air inlet pipe, which can introduce gas into the vortex tube 200. Then, part of the gas is introduced into the internal of the low-temperature outlet pipe 312 through the cold air end of the vortex tube 200. The temperature value of the cold air end can be appropriately adjusted according to the processing material and the processing season environment. It is optimal to keep the temperature at four degrees Celsius, plus or minus three degrees Celsius. It is only necessary to ensure that the copper wire has a cooling effect. The specific temperature value is appropriately adjusted according to the actual situation. The cold air inside the low-temperature outlet pipe 312 is introduced into the spiral tube 313. Through the spiral tube 313, the temperature of the air inlet channel 311 is reduced, so that the moisture carried by the gas to be introduced into the air inlet channel 311 can be quickly condensed. Then, the external gas is introduced into the low-temperature component 320 through the air inlet channel 311 to air-cool the split copper wire. At the same time, the moisture during the air-cooling process can also be reduced, and the generation of condensed liquid on the surface of the photovoltaic solder tape copper wire is reduced;

[0042] Through the setting of the middle low-temperature tube 317, the middle low-temperature tube 317 is located on the central axis of the air inlet channel 311. And through the middle low-temperature tube 317, the condensation effect on the gas inside the air inlet channel 311 is improved, and the low-temperature gas is guided to the cooling middle tube 321 through the low-temperature outlet tube 318; The surface of the middle low-temperature tube 317 is fixedly connected to the surface of the spiral temperature guide plate 315. The spiral temperature guide plate 315 is set in a spiral shape. When the gas enters the inside of the air inlet channel 311, it fully contacts the surface of the spiral temperature guide plate 315 in a spiral shape. And because the fixed sleeve 314 can conduct the low temperature of the spiral tube 313 to the spiral temperature guide plate 315, and through the middle low-temperature tube 317, the overall temperature of the spiral temperature guide plate 315 is kept balanced, so that the moisture in the cooling gas can get a better condensation effect when the gas entering the inside of the air inlet channel 311 passes through the spiral temperature guide plate 315, reducing the occurrence of the situation that condensed liquid is generated on the surface of the photovoltaic solder tape copper wire during cooling;

[0043] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10As shown in the figure, the low-temperature component 320 includes a cooling middle tube 321 fixedly connected to the inner wall of the low-temperature liquid tank 100. Both ends of the cooling middle tube 321 penetrate to the outside of the low-temperature liquid tank 100. Temperature conduction connectors 322 are fixedly connected to both sides of the cooling middle tube 321. The other ends of the temperature conduction connectors 322 are fixedly connected to the inner wall of the low-temperature liquid tank 100. A low-temperature sleeve 323 is sleeved on the surface of the cooling middle tube 321. The surface of the low-temperature sleeve 323 is embedded in the interior of the temperature conduction connector 322. The low-temperature sleeve 323 communicates with the end of the dehumidification component 310. Two first colloid spiral plates 326 are fixedly connected to the inner wall of the cooling middle tube 321 near the end. The first colloid spiral plates 326 are spiral-shaped. The two first colloid spiral plates 326 are arranged in a mirror image. A second colloid spiral plate 327 is fixedly connected to the side of one first colloid spiral plate 326 close to the other first colloid spiral plate 326. The second colloid spiral plate 327 is fixedly connected to the inner wall of the cooling middle tube 321. Air inlet notches 328 are evenly arranged on the inner edge of the second colloid spiral plate 327. The other end of the low-temperature sleeve 323 communicates with a cooling coil 324. The other end of the cooling coil 324 is fixedly connected to an injection gas pipe 325. The other end of the injection gas pipe 325 penetrates into the interior of the air inlet channel 311. The cooling coil 324 is arranged in an S shape.

[0044] Among them, a temperature conduction liquid is stored inside the low-temperature liquid tank 100. Since the cooling middle tube 321 is located inside the low-temperature liquid tank 100, the cooling middle tube 321 is maintained at a low temperature, which assists the dehumidification component 310 to produce a good air-cooling effect on the copper wire. By arranging the low-temperature sleeve 323 sleeved on the surface of the cooling middle tube 321, the effect of the temperature conduction liquid assisting in cooling the cooling middle tube 321 is improved. And while the temperature conduction connector 322 cooperates with the low-temperature liquid tank 100 to enhance the positioning effect on the cooling middle tube 321, it can also assist in positioning the low-temperature sleeve 323. At the same time, the temperature conduction connector 322 can conduct the low temperature on the surface of the low-temperature sleeve 323 to the cooling middle tube 321, so that the cooling middle tube 321 maintains a relatively low temperature. The air inlet channel 311 communicates with the cooling middle tube 321. When the cooling gas is introduced into the cooling middle tube 321 through the air inlet channel 311, since the cooling middle tube 321 maintains a low-temperature state, the air-cooling effect of the low-temperature gas on the photovoltaic solder strip copper wire is ensured.

[0045] The gas is introduced into the middle cooling tube 321 through the air inlet channel 311, and the gas is discharged from both ends of the middle cooling tube 321. At this time, due to the cooperation of the first colloidal spiral plate 326 and the second colloidal spiral plate 327, which obstruct the air flow, the gas flow rate is increased, improving the air-cooling effect on the copper wire of the photovoltaic welding tape. At the same time, the materials of the first colloidal spiral plate 326 and the second colloidal spiral plate 327 can be colloidal components. While reducing the oscillation of the copper wire driven by the air flow, the first colloidal spiral plate 326 and the second colloidal spiral plate 327 can relieve the amplitude of the copper wire when contacting the copper wire. Moreover, the first colloidal spiral plate 326 is spirally arranged, which can extend the contact path of part of the gas and the copper wire, improving the air-cooling effect. And the first colloidal spiral plate 326 and the second colloidal spiral plate 327 cooperate with the inner wall of the middle cooling tube 321 to form an air duct. Through the provided air inlet notch 328, part of the low-temperature air flow can be assisted to be discharged in time after heat exchange, so that the subsequent low-temperature gas can be replenished in time, ensuring the cooling effect of the gas on the copper wire. The low-temperature sleeve 323 guides the low-temperature gas into the cooling coil 324. Since the shape of the cooling coil 324 improves the cooling effect on the liquid in the low-temperature liquid tank 100, it assists in ensuring the relatively low-temperature effect of the middle cooling tube 321, reducing the excessive heat loss generated when the gas in the air inlet channel 311 enters the middle cooling tube 321, and assisting the dehumidification component 310 to air-cool and cool the copper wire of the photovoltaic welding tape;

[0046] As Figure 1 , Figure 2 , Figure 3 , Figure 11 , Figure 12 As shown, the moisture removal component 330 includes two connecting frames 331 fixedly connected to the ends of the low-temperature liquid tank 100. The other ends of the two connecting frames 331 are fixedly connected with an air storage chamber 332. The surface of the air storage chamber 332 is communicated with a high-temperature air outlet pipe 334, and the high-temperature air outlet pipe 334 is communicated with the hot air end of the vortex tube 200. The inner wall of the air storage chamber 332 is rotatably connected with a sprocket 333, and the upper end of the air storage chamber 332 extends above the sprocket 333; Two fixing seats 335 are fixedly connected between the two connecting frames 331. The inner wall of the fixing seat 335 is fixedly connected with a sponge cone sleeve 336. The sponge cone sleeve 336 is conical. An air guide cavity 337 is opened inside the air storage chamber 332. The inner wall of the air guide cavity 337 is fixedly connected with two groups of guide plates 338, and the two groups of guide plates 338 are arranged staggeredly;

[0047] Among them, the temperature value at the hot gas end can be appropriately adjusted according to the processing material and the processing season environment. The temperature is optimally maintained at 23 degrees Celsius, with a tolerance of plus or minus 3 degrees Celsius. It is only necessary to ensure that the copper wire of the photovoltaic solder ribbon has a cooling effect. The specific temperature value can be appropriately adjusted according to the actual situation. The copper wire inside the cooling middle tube 321 is led out and passes through the sheave 333. At this time, since the sheave 333 is installed inside the air chamber 332, and the gas is introduced into the air chamber 332 through the high-temperature gas outlet pipe 334, the copper wire of the photovoltaic solder ribbon is cooled and then the air flow is guided through the air chamber 332 to the groove part of the sheave 333 through the high-temperature gas outlet pipe 334, making the temperature of the copper wire of the photovoltaic solder ribbon closer to room temperature and ensuring good metal properties. The sponge cone sleeve 336 can be used to assist in wiping and adsorbing the coolant droplets on the surface of the copper wire of the photovoltaic solder ribbon, reducing the residual liquid on the surface of the copper wire of the photovoltaic solder ribbon and reducing the corrosion of the metal material. The high-temperature gas outlet pipe 334 introduces the gas into the air chamber 332. At this time, the gas blows towards the flow guide plate 338. Under the guidance of the two groups of staggeredly distributed flow guide plates 338, the air flow can be converged towards the copper wire of the photovoltaic solder ribbon to ensure the blowing effect on the surface of the copper wire of the photovoltaic solder ribbon.

[0048] Working principle:

[0049] The gas is introduced into the vortex tube 200 through the high-pressure gas inlet pipe. Part of the gas is introduced into the internal part of the low-temperature outlet pipe 312 through the cold air end of the vortex tube 200. The cold air inside the low-temperature outlet pipe 312 is introduced into the spiral tube 313 and the temperature is reduced through the air inlet 311 of the spiral tube 313. The moisture carried by the gas to be introduced is quickly condensed through the air inlet 311. The external gas is introduced into the low-temperature component 320 through the air inlet 311 to air-cool the copper wire of the photovoltaic welding tape. Through the setting of the middle low-temperature pipe 317, the middle low-temperature pipe 317 is located on the central axis of the air inlet 311. The condensation effect of the gas inside the air inlet 311 is improved through the middle low-temperature pipe 317, and the low-temperature gas is guided to the cooling middle pipe 321 through the low-temperature outlet pipe 318; the spiral heat conduction plate 315 is set in a spiral shape. When the gas enters the inside of the air inlet 311, it fully contacts the surface of the spiral heat conduction plate 315 in a spiral shape. The fixing sleeve 314 conducts the low temperature of the spiral tube 313 to the spiral heat conduction plate 315, and the overall temperature of the spiral heat conduction plate 315 is kept balanced through the middle low-temperature pipe 317; a heat conduction liquid is stored inside the low-temperature liquid tank 100. The cooling middle pipe 321 is located inside the low-temperature liquid tank 100 to keep the cooling middle pipe 321 at a low temperature, assisting the dehumidification component 310 to produce a good air-cooling effect on the copper wire of the photovoltaic welding tape. The heat conduction connecting piece 322 cooperates with the low-temperature liquid tank 100 to enhance the positioning effect on the cooling middle pipe 321 and assist in positioning the low-temperature sleeve 323. The heat conduction connecting piece 322 conducts the low temperature on the surface of the low-temperature sleeve 323 to the cooling middle pipe 321. The cooling middle pipe 321 maintains a relatively low temperature. The air inlet 311 is communicated with the cooling middle pipe 321, and the cooling gas is introduced into the cooling middle pipe 321 through the air inlet 311; the gas is introduced into the cooling middle pipe 321 through the air inlet 311, and the gas is discharged to both ends of the cooling middle pipe 321. Due to the cooperation of the first colloid spiral plate 326 and the second colloid spiral plate 327, the gas flow rate increases. The first colloid spiral plate 326 is spirally arranged to extend the contact path of part of the gas with the copper wire of the photovoltaic welding tape. The low-temperature sleeve 323 guides the low-temperature gas to the cooling coil 324, and the dehumidification component 310 air-cools and cools the copper wire of the photovoltaic welding tape.
