Manufacturing process of cooling and cooling equipment
Dec 13, 2024| The manufacturing process of cooling equipment mainly includes the following key steps:
Material preparation: Choose suitable semiconductor materials, such as bismuth telluride (Bi ₂ Te ∝), which are key to generating thermoelectric effects. At the same time, prepare metal wires, insulation materials, cooling media, packaging materials, and possible ceramic sheets (for support and packaging)
Chip cutting and preparation: Cutting semiconductor materials into chips of the desired shape and size in a clean environment, and surface treating the chips to improve their performance and stability
Component assembly: P-type and N-type semiconductor chips are assembled into thermocouples through specific processes, usually by sandwiching them between ceramic plates and sealing and fixing them with silicone sealant. During the assembly process, it is important to ensure good contact between components to achieve efficient heat transfer
Circuit connection: Use metal wires to connect the thermocouple to the power supply and control circuit, ensuring smooth current flow and generating cooling effect
Design of heat dissipation and refrigeration system: Design and install radiators and cooling fins to ensure that heat can be effectively transferred from the cooling fins to the radiators and dissipated into the environment
Performance testing: Conduct performance testing on the assembled semiconductor refrigeration device, including indicators such as refrigeration efficiency, stability, durability, etc. Use advanced testing equipment and methods, such as ultrasonic scanning field mirrors, to conduct detailed testing and analysis of the device
Debugging and optimization: Debug and optimize the device based on test results to ensure its performance meets design requirements. Repair or scrap non-conforming products to ensure product quality
Encapsulation and packaging: Encapsulate the tested semiconductor refrigeration device to protect its internal components from external environmental influences. Use appropriate packaging materials for transportation and sales
Maintenance and upkeep: After production is completed, it is recommended to perform regular maintenance on the semiconductor refrigeration unit to extend its service life and maintain good performance. Provide detailed maintenance and upkeep manuals to users, guiding them in the correct use and maintenance of equipment
