Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, specifically a cartridge-type thermal reactor body. Background Technology

[0002] In the manufacturing process of photovoltaic cells, after screen printing, the paste is placed on the surface of the cell. A drying oven is then used to dry the cell to solidify the paste. Generally, two types of drying ovens are used: flat-lay type and snap-fit ​​type. The snap-fit ​​type drying oven has a cavity in which the cell moves. During this movement, the paste on the cell is dried and solidified by hot air from the oven. An exhaust unit is located on the side of the cavity to expel hot air. In existing technology, the exhaust unit has a receiving groove on the base plate, where a heating rod is locked. The heating rod heats the surrounding base plate, thus heating the gas passing through it. However, in actual production, it has been found that there is a large temperature difference between the base plate and the heating rod, as well as uneven temperature distribution. This results in low thermal efficiency, ultimately making it difficult to meet the required temperature for the high-temperature gas entering the cavity through the base plate, and causing significant temperature differences in different areas, leading to poor drying and solidification of the cell. Utility Model Content

[0003] In order to overcome the defects in the prior art, this utility model provides a cartridge-type thermal reactor body, which is used to solve one or more of the above-mentioned problems.

[0004] This application discloses a cartridge-type thermal reactor body, including a first chamber and a second chamber disposed correspondingly, forming a furnace cavity between the first chamber and the second chamber. The furnace cavity has an exhaust unit and an intake unit located on the first chamber on both sides. The exhaust unit has an exhaust chamber and an exhaust heating assembly located between the furnace cavity and the exhaust chamber. The exhaust heating assembly includes: a base plate located between the furnace cavity and the exhaust chamber, with first through holes distributed on the base plate; a receiving groove on the side of the base plate adjacent to the exhaust heating assembly, the receiving groove being used to house a heating rod; and thermally conductive silicone grease disposed inside the receiving groove, the thermally conductive silicone grease covering the outside of the heating rod and filling the inside of the receiving groove; and a cover plate located on the side of the base plate adjacent to the exhaust chamber, with second through holes distributed on the cover plate, the cover plate abutting against the top wall of the receiving groove away from the furnace cavity.

[0005] Furthermore, the exhaust heating assembly also includes a flow equalization plate, which is located on the side of the bottom plate adjacent to the furnace cavity. The relative position of the flow equalization plate and the bottom plate is adjustable. A third through hole is distributed on the flow equalization plate, and the size of the third through hole corresponds to that of the first through hole.

[0006] Furthermore, the base plate and the cover plate are fixedly connected, the first through hole and the second through hole are correspondingly arranged, and multiple flow equalization plates are arranged sequentially along the extension direction of the base plate. The base plate, the cover plate and the flow equalization plates are all made of the same material.

[0007] Furthermore, it also includes a temperature sensing unit, which includes a temperature sensor passing through the third through hole and a temperature controller electrically connected to the temperature sensing unit. The end of the temperature sensing unit away from the flow equalizer is located inside the furnace cavity, and the temperature controller can be used to adjust the temperature of the heating rod.

[0008] Furthermore, the flow equalization plate has an oval adjustment part, and the base plate and the flow equalization plate can be fixed at different positions in the oval adjustment part to change the corresponding positions of the first through hole and the third through hole.

[0009] Furthermore, the oval adjustment part is an oval through groove that passes through the flow equalization plate, and the bottom plate is provided with a threaded groove corresponding to the width of the oval adjustment part. The threaded groove and different positions of the oval adjustment part are detachably connected by screws.

[0010] Furthermore, the exhaust unit also includes a preheating component located on the side of the exhaust chamber away from the exhaust heating component. The preheating component includes: a preheating chamber having a preheating section for preheating gas; and a gas guiding section for guiding gas in the preheating chamber to the exhaust chamber.

[0011] Furthermore, the air intake unit has an air intake chamber and an air intake mesh plate located between the furnace cavity and the air intake chamber. The air intake chamber extends from the side of the furnace cavity to the lower part of the furnace cavity, and the preheating chamber communicates with the air intake chamber located in the lower part of the furnace cavity.

[0012] Furthermore, the second housing is located at the upper end of the first housing, the edges of the first housing and the second housing are hinged together, and the first housing and the second housing together form the furnace cavity. The top of the second housing has a plurality of spaced exhaust ports in the extending direction of the furnace cavity, and the exhaust ports are used to discharge the exhaust gas in the furnace cavity.

[0013] Furthermore, the second housing includes a housing frame and a housing body covering the housing frame. A through groove is provided on the bottom wall of the housing frame near the furnace cavity, and the housing body covers the through groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By placing thermally conductive silicone grease inside the accommodating groove, the heating rod can first exchange heat with the thermally conductive silicone grease, and then the thermally conductive silicone grease heats the base plate through heat exchange, so that the temperature of the base plate is close to that of the heating rod, and the temperature of the base plate is relatively uniform. This improves the thermal efficiency of the heating rod in the heating process of the base plate, so that the high-temperature gas entering the furnace cavity through the first through hole can reach a higher temperature, and the temperature of the high-temperature gas in different areas of the furnace cavity remains the same, thereby eliminating the temperature difference in different areas of the furnace cavity, and thus achieving a better drying and curing effect on the battery cells in the furnace cavity.

[0016] 2. By adjusting the relative position of the flow equalization plate and the bottom plate, the corresponding areas of the first through hole and the second through hole can be changed, thereby changing the gas flow rate from the third through hole to the furnace cavity, and thus changing the gas flow rate of the high-temperature gas in the furnace cavity. This achieves the effect of changing the high-temperature gas flow rate in the furnace cavity, resulting in better control over the temperature and air volume in the furnace cavity.

[0017] 3. This enables the temperature controller to adjust the temperature of the heating rod based on the temperature signal from the temperature sensor, thereby changing the temperature of the base plate and consequently changing the temperature of the high-temperature gas flowing through the first through hole, thus achieving dynamic temperature regulation inside the furnace cavity.

[0018] 4. By changing the connection position between the base plate and the waist-shaped adjustment part, the corresponding areas of the first through hole and the third through hole change, thereby changing the gas flow rate entering the third through hole through the first through hole, so as to achieve the effect of adjusting the air volume of the third through hole.

[0019] 5. By setting a preheating component, the preheating component can preheat the air before it enters the exhaust chamber, thereby increasing the temperature of the gas in the exhaust chamber. Through the preheating effect of the preheating component combined with the secondary heating effect of the exhaust heating component, the gas entering the furnace chamber can maintain a high temperature.

[0020] 6. A unidirectional gas flow channel is formed, from the furnace cavity to the air inlet chamber, then to the preheating chamber, then to the exhaust chamber, and then back into the furnace cavity via the exhaust heating component, finally exiting the furnace cavity through the waste outlet. This allows the high-temperature gas used to dry the battery cells in the furnace cavity to be discharged from the furnace cavity through the waste outlet, while the air entering the furnace cavity from both sides enters the air inlet chamber again and is finally heated into high-temperature gas and transported into the furnace cavity. This achieves unidirectional gas circulation, resulting in high purity of the high-temperature gas used to dry the battery cells, and avoiding the situation where too many impurities in the high-temperature gas reduce the drying effect.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1 to 9 The illustration shows a cartridge-type thermal reactor body, comprising a first housing 1 and a second housing 2 arranged correspondingly, forming a furnace cavity 3 between the first housing 1 and the second housing 2. The first housing 1 and the second housing 2 can be closed to form the furnace cavity 3, thereby providing space for the drying and curing of battery cells. The furnace cavity 3 has an exhaust unit 4 and an air inlet unit 5 located on the first housing 1 on both sides. The exhaust unit 4 is used to exhaust heated high-temperature gas into the furnace cavity 3, and the air inlet unit 5 is used to draw in air from the furnace cavity 3 and ultimately deliver it to the exhaust unit 4. The exhaust unit 4 has an exhaust chamber 41 and an exhaust heating assembly 42 located between the furnace cavity 3 and the exhaust chamber 41. The exhaust heating assembly 42 includes:

[0035] A base plate 421 is located between the furnace cavity 3 and the exhaust chamber 41. The base plate 421 has first through holes 4211 distributed on it, allowing high-temperature gas from the exhaust chamber 41 to flow into the furnace cavity 3 via the first through holes 4211. The base plate 421 has a receiving groove 4212 on the side adjacent to the exhaust heating assembly 42. A heating rod 4213 is placed inside the receiving groove 4212. The heating rod 4213 is located within the receiving groove 4212, allowing it to heat the gas flowing from the exhaust chamber 41 to the furnace cavity 3. This ensures that the gas entering the furnace cavity 3 is heated to a high temperature by the heating rod 4213 as it flows through the exhaust heating assembly 42, allowing the battery cells to be dried and cured by the high-temperature gas in the furnace cavity 3.

[0036] The receiving groove 4212 is also provided with thermally conductive silicone grease 424. The thermally conductive silicone grease 424 covers the outside of the heating rod 4213 and fills the inside of the receiving groove 4212, so that the thermally conductive silicone grease 424 is between the heating rod 4213 and the base plate 421 and the cover plate 422. Thus, the thermally conductive silicone grease 424 can fill the inside of the receiving groove 4212. During the heating process of the heating rod 4213, the temperature in the heating rod 4213 is conducted to the thermally conductive silicone grease 424, and then the thermally conductive silicone grease 424 transfers the heat to the base plate 421, so that the temperature of the base plate 421 can be kept stable. As a result, the gas in the exhaust chamber 41 enters the furnace cavity 3 through the exhaust heating assembly 42 and is in a high-temperature state with uniform temperature.

[0037] A cover plate 422 is located on the side of the base plate 421 adjacent to the exhaust chamber 41. The cover plate 422 has second through holes 4221 distributed on it, which allow gas in the exhaust chamber 41 to pass through the cover plate 422 and flow to the first through hole 4211 in the base plate 421. The cover plate 422 abuts against the top wall of the receiving groove 4212 away from the furnace cavity 3, thereby allowing the cover plate 422 to fix the heating rod 4213 and the thermal grease 424 located in the receiving groove 4212. This makes the structure of the entire exhaust heating assembly 42 more stable and avoids instability of the thermal grease 424 or the heating rod 4213 during operation.

[0038] In this embodiment, the silicon wafer basket carrying multiple layers of solar cells moves from one end to the other in the furnace cavity 3. During this process, air continuously enters from the outside into the furnace cavity 3 from both ends. The air intake unit 5 draws in the air from the furnace cavity 3 and finally delivers it to the exhaust unit 4. The air enters the exhaust chamber 41 and then flows through the second through hole 4221 to the first through hole 4211. During this process, the heating rod 4213 heats the air to conduct heat to the thermally conductive silicone grease 424, which in turn conducts heat to the base plate 421. This makes the temperature of the base plate 421 uniform, thereby ensuring that the air flowing through the first through hole 4211 can be heated evenly, so that the temperature of the air entering the furnace cavity 3 through the first through hole 4211 can be kept high and more stable. It is worth noting that the gas in this embodiment is air entering from both ends of the furnace cavity. Of course, in other embodiments, it can also be replaced with gases such as nitrogen to prevent oxidation of the solar cells during the drying process.

[0039] With the above structure, by providing thermally conductive silicone grease 424 inside the receiving groove 4212, the heating rod 4213 can first exchange heat with the thermally conductive silicone grease 424, and then the thermally conductive silicone grease 424 heats the base plate 421 through heat exchange, so that the temperature of the base plate 421 is close to that of the heating rod 4213, and the temperature of the base plate 421 is relatively uniform. This improves the thermal efficiency of the heating rod 4213 in heating the base plate 421, so that the high-temperature gas entering the furnace cavity 3 through the first through hole 4211 can reach a higher temperature, and the temperature of the high-temperature gas in different areas of the furnace cavity 3 remains the same, thereby eliminating the temperature difference in different areas of the furnace cavity 3, and thus achieving a better drying and curing effect on the battery cells in the furnace cavity 3.

[0040] Specifically, such as Figure 5 , Figure 7 and Figure 9 As shown, the exhaust heating assembly 42 also includes a flow equalization plate 423. The flow equalization plate 423 is located on the side of the bottom plate 421 adjacent to the furnace cavity 3. The relative position of the flow equalization plate 423 and the bottom plate 421 is adjustable. The flow equalization plate 423 is provided with a third through hole 4231. The size of the third through hole 4231 corresponds to that of the first through hole 4211, so that the high-temperature gas flowing out of the first through hole 4211 can flow to the third through hole 4231 and then flow into the furnace cavity 3 through the third through hole 4231.

[0041] By adjusting the relative positions of the flow equalization plate 423 and the bottom plate 421, the corresponding areas of the first through hole 4211 and the second through hole 4221 can be changed, thereby altering the gas flow rate from the third through hole 4231 to the furnace cavity 3, and consequently changing the gas flow rate of the high-temperature gas in the furnace cavity 3. This achieves the effect of changing the high-temperature gas flow rate in the furnace cavity 3, resulting in better control over the temperature and air volume in the furnace cavity 3.

[0042] Specifically, such as Figure 5 and Figure 6 As shown, the base plate 421 and the cover plate 422 are fixedly connected, thereby providing a good connection between the cover plate 422 and the base plate 421, and ensuring good stability for the heating rod 4213 and the thermal grease 424 located in the receiving groove 4212. The first through hole 4211 and the second through hole 4221 are correspondingly arranged. Preferably, the first through hole 4211 and the second through hole 4221 have the same shape, making the gas flow smoother. Of course, in other optional embodiments, the shapes of the first through hole 4211 and the second through hole 4221 can be adjusted according to actual needs. Multiple flow equalization plates 423 are arranged sequentially along the extension direction of the base plate 421, allowing for position adjustment of different flow equalization plates 423 to change the corresponding area of ​​the third through hole 4231 on different flow equalization plates 423 and the first through hole 4211 on the base plate 421, achieving precise control of gas flow rate. The base plate 421, the cover plate 422, and the flow equalization plate 423 can all be made of the same material, thus having the same coefficient of thermal expansion. In this embodiment, the base plate 421, the cover plate 422, and the flow equalization plate 423 are all aluminum plates, which gives them good thermal conductivity. Of course, in other optional embodiments, the materials of the base plate 421, the cover plate 422, and the flow equalization plate 423 can be adjusted according to actual needs.

[0043] Specifically, such as Figure 3As shown, it also includes a temperature sensing unit 6, which includes a temperature sensor passing through the third through hole 4231 and a temperature controller electrically connected to the temperature sensing unit 6. The end of the temperature sensing unit 6 away from the flow equalization plate 423 is located inside the furnace cavity 3, so that the temperature sensor can be used to sense the temperature inside the furnace cavity 3. Then, the temperature sensor unit transmits an electrical signal to the temperature controller, which can be used to adjust the temperature of the heating rod 4213. Thus, the temperature controller can adjust the temperature of the heating rod 4213 according to the temperature signal of the temperature sensor, thereby changing the temperature of the bottom plate 421, and further changing the temperature of the high-temperature gas flowing through the first through hole 4211, realizing the dynamic adjustment effect of the internal temperature of the furnace cavity 3.

[0044] Specifically, such as Figure 8 and Figure 9 As shown, the flow equalization plate 423 has an oval adjustment part 4232. The base plate 421 and the flow equalization plate 423 can be fixed at different positions in the oval adjustment part 4232, so that the connection position between the base plate 421 and the flow equalization plate 423 can be changed, so that the corresponding positions of the first through hole 4211 and the third through hole 4231 can be adjusted.

[0045] Preferably, the oblong adjustment part 4232 is an oblong through groove that passes through the flow equalization plate 423. The bottom plate 421 has a threaded groove 4214 corresponding to the width of the oblong adjustment part 4232. The threaded groove 4214 and the oblong adjustment part 4232 are detachably connected by screws at different positions. This allows the relative position of the flow equalization plate 423 and the bottom plate 421 to be changed by changing the relative position of the threaded groove 4214 and the oblong adjustment part 4232, so that the bottom plate 421 and the flow equalization plate 423 can change between a first state and a second state.

[0046] In the first state, the first through hole 4211 and the third through hole 4231 are completely corresponding, thereby maximizing the gas flow rate from the first through hole 4211 to the third through hole 4231; in the second state, the third through hole 4231 is misaligned with the first through hole 4211, thereby preventing the gas flowing out of the first through hole 4211 from being discharged through the third through hole 4231, thus minimizing the gas flow rate.

[0047] By using the above structure, by changing the connection position between the base plate 421 and the waist-shaped adjustment part 4232, the corresponding areas of the first through hole 4211 and the third through hole 4231 are changed, thereby changing the gas flow rate entering the third through hole 4231 through the first through hole 4211, so as to achieve the effect of adjusting the air volume of the third through hole 4231.

[0048] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the exhaust unit 4 further includes a preheating component 43 located on the side of the exhaust chamber 41 away from the exhaust heating component 42, the preheating component 43 comprising:

[0049] The preheating chamber 431 has a preheating section 432 inside for preheating gas. In this embodiment, the preheating section 432 is a heating fin that passes through the preheating chamber 431, thereby improving the heat conversion efficiency of the air in the preheating chamber 431. Of course, in other optional embodiments, the actual structure of the preheating section 432 can be adjusted according to actual needs.

[0050] The gas guide section 433 is used to guide the gas in the preheating chamber 431 to the exhaust chamber 41. In this embodiment, the gas guide section 433 is an exhaust fan between the preheating chamber 431 and the exhaust chamber 41, thereby achieving the effect of guiding the gas from the preheating chamber 431 to the exhaust chamber 41. In addition, it is worth noting that the gas guide section 433 can serve as the power source for the entire air duct, so as to achieve the effect of air flowing from the furnace cavity 3 to the air intake unit 5 and from the air intake unit 5 to the preheating chamber 431.

[0051] With the above structure, by setting the preheating component 43, the preheating component 43 can preheat the air before it enters the exhaust chamber 41, thereby increasing the temperature of the gas in the exhaust chamber 41. Through the preheating effect of the preheating component 43 combined with the secondary heating effect of the exhaust heating component 42, the gas entering the furnace chamber 3 can maintain a high temperature.

[0052] Specifically, such as Figures 1 to 4 As shown, the air intake unit 5 has an air intake chamber 51 and an air intake mesh plate 52 located between the furnace cavity 3 and the air intake chamber 51. The air intake mesh plate 52 is used to allow air to circulate in the furnace cavity 3 and enter the air intake chamber 51, and can also filter impurities in the furnace cavity 3 to prevent impurities in the furnace cavity 3 from entering the air intake chamber 51. The air intake chamber 51 extends from the side of the furnace cavity 3 to the lower part of the furnace cavity 3, and the preheating chamber 431 communicates with the air intake chamber 51 located in the lower part of the furnace cavity 3.

[0053] With the above structure, fresh air in the furnace cavity 3 can enter the preheating cavity 431 through the air inlet chamber 51 and finally enter the exhaust chamber 41, so that the high-temperature gas that finally enters the furnace cavity 3 can have a smooth and space-saving gas flow channel, improving the space utilization of the entire structure.

[0054] Specifically, such as Figures 1 to 4 As shown, the second housing 2 is located at the upper end of the first housing 1. The edges of the first housing 1 and the second housing 2 are hinged, allowing the first housing 1 and the second housing 2 to be separated or closed, thus providing a good connection between them. The first housing 1 and the second housing 2 together form the furnace cavity 3. The top of the second housing 2 has multiple spaced exhaust ports in the extending direction of the furnace cavity 3, which are used to discharge waste gas from the furnace cavity 3.

[0055] With the above structure, a one-way gas flow channel is formed, from the furnace cavity 3 to the air inlet chamber 51, then to the preheating chamber 431, then to the exhaust chamber 41, and then into the furnace cavity 3 via the exhaust heating component 42, and finally discharged from the furnace cavity 3 through the exhaust port. This allows the high-temperature gas after drying the battery cells in the furnace cavity 3 to be discharged from the furnace cavity 3 through the exhaust port, while the air entering the furnace cavity 3 from both sides enters the air inlet chamber 51 again and is finally heated into high-temperature gas and transported into the furnace cavity 3. This achieves one-way gas circulation, resulting in high purity of the high-temperature gas used to dry the battery cells, and avoiding the situation where too many impurities in the high-temperature gas reduce the drying effect.

[0056] Specifically, such as Figure 4 As shown, the second box 2 includes a box frame 21 and a box body 22 covering the box frame 21. A through groove 211 is provided on the bottom wall of the box frame 21 near the furnace cavity 3. The box body 22 covers the through groove 211. Through repeated research by the inventors, it has been found that if the second box 2 is a single piece of frame, deformation of the second box 2 will occur during the high-temperature drying process. This is because the deformation of the box body under high temperature causes excessive local stress. By providing the through groove 211 on the box frame 21, the entire frame can be divided into multiple small areas. The stress of the frame in each small area under high temperature is limited, thereby avoiding excessive stress on the entire frame. Then, covering the box body 22 on the box frame 21 can increase the strength of the entire second box 2, so that the box frame 21 still has good structural stability under high-temperature drying, avoiding the problem of deformation of the second box 2 under high-temperature drying, and making the structure of the entire second box 2 more stable.

At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model.
