Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology, and specifically relates to a cooling device for perovskite components. Background Technology

[0002] Perovskite materials, due to their unique physicochemical properties, have shown great application potential in many high-tech industries such as solar cells, light-emitting diodes, and sensors, becoming one of the research hotspots. The perovskite preparation process is complex and delicate, with each step having stringent temperature requirements, among which the cooling stage plays a crucial role.

[0003] Currently, perovskite is typically cooled using direct air cooling or water cooling during its preparation. However, direct air cooling relies on natural airflow or simple fans, which inherently have low heat exchange efficiency. In large-scale, continuous perovskite preparation, achieving ideal cooling requires prolonged and intensive fan operation, resulting in significant energy consumption and waste. Water cooling, on the other hand, carries the risk of moisture intrusion into the perovskite material. Once moisture enters, it affects the quality of the perovskite material, leading to a high rate of damage to perovskite components. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cooling device for perovskite components, which can reduce energy consumption and isolate water vapor during the preparation of perovskite components to improve the preparation quality of perovskite components.

[0005] This invention is implemented as follows: a cooling device for perovskite modules is provided, including a wafer rack, a primary cooling furnace connected to the outlet of the wafer rack, and a low-temperature cooling furnace connected to the outlet of the primary cooling furnace. The wafer rack includes: a wafer rack outer frame, and a conveying assembly disposed within the wafer rack outer frame for storing and conveying the perovskite modules to the primary cooling furnace. The primary cooling furnace includes: a first upper furnace chamber, a first lower furnace chamber, and a plurality of first cooling conveying rollers disposed between the first upper furnace chamber and the first lower furnace chamber.

[0006] Furthermore, the cryogenic cooling furnace also includes: lifting doors respectively installed at the inlet and outlet of the cryogenic cooling furnace, wherein the lifting doors are used to transfer perovskite components when open and to seal the cryogenic cooling furnace when closed.

[0007] Furthermore, the air outlet direction of the air knife device is at a 135-degree angle to the transport direction of the perovskite assembly.

[0008] Furthermore, the conveying assembly includes: two driven shafts disposed inside the upper part of the outer frame of the wafer rack; two drive shafts disposed at the bottom inside the wafer rack and corresponding to the two driven shafts; two conveyor belts respectively sleeved between the drive shafts and driven shafts; clamping points respectively disposed inside the two conveyor belts for storing perovskite components; multiple rolling wheels disposed at the outlet of the outer frame of the wafer rack; a rolling wheel motor; and a drive shaft motor. The drive shaft motor is used to drive the drive shafts to move inward, thereby rotating the conveyor belts and transferring the perovskite components at the clamping points from above the wafer rack to the rolling wheels. The rolling wheel motor is used to drive the rolling wheels to transport the perovskite components into the primary cooling furnace.

[0009] Furthermore, the first cooling conveyor roller and the second cooling conveyor roller each include: a hollow round steel roller, a rubber protective layer covering the outside of the hollow round steel roller, an inlet pipe at one end of the hollow round steel roller, and an outlet pipe at the other end.

[0014] Furthermore, the ventilation filter is a high-efficiency filter or a sub-high-efficiency filter.

[0015] Compared with existing technologies, the cooling equipment for perovskite modules of this invention rapidly cools the perovskite modules by utilizing the temperature difference between the perovskite modules and the first cooling conveyor roller, the second cooling conveyor roller, the cooling pipe, and the cooling gas.

[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Please refer to the following at the same time Figures 1-3 As shown, this utility model provides a preferred embodiment of a cooling device for perovskite modules, including a wafer rack, a primary cooling furnace 2 connected to the outlet of the wafer rack, and a low-temperature cooling furnace 3 connected to the outlet of the primary cooling furnace 2. The wafer rack includes: a wafer rack outer frame 1, and a conveying component disposed within the wafer rack outer frame 1 for storing and conveying perovskite modules to the primary cooling furnace 2.

[0024] The primary cooling furnace 2 includes: a first upper furnace chamber 4, a first lower furnace chamber 5, and a plurality of first cooling conveying rollers 6 disposed between the first upper furnace chamber 4 and the first lower furnace chamber 5. The first cooling conveying rollers 6 are used to initially cool the perovskite assembly and convey it to the cryogenic cooling furnace 3.

[0025] The cryogenic cooling furnace 3 includes: a second upper furnace chamber 7, a second lower furnace chamber 8, multiple air knife devices 9 disposed on the second upper furnace chamber 7 for supplying gas into the cryogenic cooling furnace 3, a cooling pipe 10 disposed below the multiple air knife devices 9 and connected to an external water tank for cooling the gas, and multiple second cooling conveyor rollers 11 disposed below the cooling pipes 10 and above the second lower furnace chamber 8 for transporting and cooling the perovskite components.

[0026] One end of the cooling pipe 10 is connected to a water inlet pipe, and the other end is connected to a water outlet pipe. The other ends of the water inlet pipe and the water outlet pipe are set in a water tank, so that the cooling water forms a loop between the water tank and the cooling pipe 10 to cool the gas supplied by the air knife device 9.

[0027] The first cooling conveyor roller 6, located in the primary cooling furnace 2, performs preliminary cooling of the perovskite component. The air knife device 9 delivers dry air or nitrogen to contact the cooling pipe 10, which reduces the overall temperature of the gas, increases the temperature difference between the cooling gas and the perovskite component, and improves the heat exchange efficiency.

[0028] This invention rapidly cools the calcium iron ore component by utilizing the temperature difference between the calcium iron ore component and the first cooling conveyor roller 6, the second cooling conveyor roller 11, the cooling pipe 10, and the cooling gas, thereby reducing energy consumption during the calcium iron ore cooling process.

[0029] In embodiments of this disclosure, the cryogenic cooling furnace 3 further includes lifting doors 12 respectively disposed at the inlet and outlet of the cryogenic cooling furnace 3. When the lifting doors 12 are open, they are used to transfer the perovskite components; when closed, they are used to seal the cryogenic cooling furnace 3. This provides a relatively clean environment by isolating the ilmenite components from moisture during the cooling process.

[0030] In the embodiments of this disclosure, in order to cool the perovskite module more uniformly, the air outlet direction of the air knife device 9 is at 135 degrees to the transport direction of the perovskite module.

[0031] In embodiments of this disclosure, reference is made to Figure 4 The conveying assembly includes: two driven shafts 13 disposed inside the upper part of the outer frame 1 of the wafer rack; two drive shafts 14 disposed on the bottom inner side of the outer frame 1 of the wafer rack and corresponding to the two driven shafts 13; two conveyor belts 15 respectively sleeved between the drive shafts 14 and the driven shafts 13; clamping points 16 respectively disposed inside the two conveyor belts 15 for storing perovskite components; multiple rolling wheels 17 disposed at the outlet of the outer frame 1 of the wafer rack; a rolling wheel motor; and a drive shaft motor. The drive shaft motor is used to drive the drive shafts 14 to move inward, thereby rotating the conveyor belts 15, so that the perovskite components on the clamping points 16 are transferred from above the wafer rack to the rolling wheels 17. The rolling wheel motor is used to drive the rolling wheels 17 to transport the perovskite components into the primary cooling furnace 2.

[0032] Specifically, a driven shaft 13 is provided at each end of the outlet of the outer frame 1 of the wafer rack. The driven shaft 13 is rotatably connected to the outer frame 1 of the wafer rack and is located inside the upper part of the outer frame 1 of the wafer rack. A drive shaft 14 is provided directly below the driven shaft 13. A conveyor belt is fitted between the drive shaft 14 and the driven shaft 13 on the same side. A drive shaft motor is installed on each drive shaft 14. The drive shaft motor can be installed on the outer frame 1 of the wafer rack. A roller motor is installed on one or both sides of the roller 17. The two drive shafts 14 move inward and at the same speed, driving the belt to rotate. This causes the perovskite assembly placed on the horizontal locking point 16 inside the belt on both sides to descend horizontally at a uniform speed onto the roller 17. The roller 17 rotates under the drive of the roller motor, transporting the perovskite assembly into the primary cooling furnace 2.

[0033] In embodiments of this disclosure, reference is made to Figure 5 The first cooling conveyor roller 6 and the second cooling conveyor roller 11 each include: a hollow round steel roller, a rubber protective layer 18 covering the outside of the hollow round steel roller, an inlet pipe 19 at one end of the hollow round steel roller, and an outlet pipe 20 at the other end. The other ends of the inlet pipe 19 and the outlet pipe 20 are connected to a water tank, so that the cooling water forms a cooling loop between the water tank and the first cooling conveyor roller 6, cooling the perovskite assembly while the first cooling conveyor roller 6 and the second cooling conveyor roller 11 are conveying it.

[0034] In embodiments of this disclosure, to buffer the impact force between the perovskite assembly and the first cooling conveyor roller 6 and the second cooling conveyor roller 11 during transport and to prevent the perovskite assembly from breaking, the rubber protective layer 18 has a hardness range of 50 to 90 Shore hardness.

[0035] In the embodiments of this disclosure, in order to ensure heat exchange between the perovskite assembly and the first cooling conveyor roller 6 and the second cooling conveyor roller 11, the thickness of the rubber protective layer 18 ranges from 5 to 20 mm.

[0036] In the embodiments of this disclosure, to further accelerate the heat exchange between the interior and exterior of the primary cooling furnace 2 and the cryogenic cooling furnace 3, graphene coatings are respectively applied to the first upper furnace cavity 4, the first lower furnace cavity 5, the second upper furnace cavity 7, and the second lower furnace cavity 8. The excellent thermal conductivity of graphene material ensures the exchange of temperature between the primary cooling furnace 2 and the ambient temperature with the cryogenic cooling furnace 3, thereby rapidly reducing the temperature inside the furnace cavity.

[0037] In the embodiments of this disclosure, in order to ensure both the cleanliness and heat dissipation function of the storage rack, a ventilation filter 21 is provided on the top of the outer frame 1 of the storage rack.

[0038] Specifically, the ventilation filter 21 is a high-efficiency filter or a sub-high-efficiency filter.

[0039] Compared with the prior art, the cooling device for perovskite modules of this utility model achieves rapid and uniform cooling of the perovskite modules by utilizing the temperature difference between the perovskite modules and the first cooling conveyor roller 6, the second cooling conveyor roller 11, the cooling pipe 10, and the cooling gas. This reduces energy consumption during the cooling process, making it more energy-efficient. Furthermore, the perovskite modules are transported in a relatively sealed device during the cooling section, preventing contact with water vapor and ensuring a clean environment for the perovskite modules during the cooling process, thereby improving the quality of the perovskite modules produced.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
