1. Introduction to Finned Heat ExchangersFinned heat exchangers are widely utilized in various applications, characterized by the addition of fins to traditional heat exchange tubes. These fins significantly increase the surface area for contact with external fluids, thereby improving heat transfer

With the continuous rise in prices of materials like copper, the call for "aluminum replacing copper" is once again heard in the Chinese household appliance industry. Among these, the use of all-aluminum microchannel heat exchangers in household air conditioners to replace copper tube fin heat exchangers has garnered attention.

Heat transfer performance is one of the crucial performance indicators of threaded inner tubes, and the tooth shape of threaded inner tubes has a significant impact on their heat transfer performance. Generally speaking, the larger the tooth shape of the threaded inner tube, the better its heat tran

In finned heat exchangers, the fins are typically made of copper, stainless steel, or aluminum alloy, with most heat exchangers utilizing aluminum alloy as the material for fins, referred to as "aluminum foil". The thickness of aluminum foil varies depending on different operating conditions of the
