Abstract: As the core power component of the refrigerator system, during the operation of the refrigerator compressor, the internal pump body core will generate obvious vibration, and the inner exhaust pipe is one of the main paths for this vibration to be transmitted outward. Focuses on the problem of excessive vibration that occurs when a certain compressor is matched with a customer's refrigerator system. Starting from the optimization of the vibration transmission path, the structure of the inner exhaust pipe is improved to enhance its flexibility, thereby reducing vibration transmission. To ensure the reliability of the optimization plan, a technical approach combining theoretical simulation and experimental testing was adopted to systematically verify the feasibility of the new plan. Ultimately, the vibration problem of the refrigerator system was effectively resolved, providing technical support for enhancing the product's market competitiveness and expanding market share.
