AI Technical Summary
Dust and impurities easily adhere to the surface of the heat exchanger fins in existing cold storage refrigeration units, leading to reduced heat exchange efficiency.
It adopts a compact finless microtube heat exchanger, which increases the contact area of the coolant through the cooperation of the shell, microtubes and condenser tubes. It uses S-shaped microtubes for transfer cooling, avoids dust and impurities from affecting heat exchange, and achieves rapid installation and positioning through the installation components.
It improves heat exchange efficiency, ensures safe and reliable operation of equipment in cold storage, avoids dust and impurities covering the fin surface, and enhances the heat exchange capacity of the refrigerant.
