AI Technical Summary
When traditional parallel flow heat exchangers replace multi-row tube-fin heat exchangers, multiple individual heat exchangers need to be arranged side by side, which increases production costs and complexity, and makes flow control complicated, affecting product qualification rate.
The heat exchanger adopts a multi-row structure, with each row containing multiple heat exchanger cores. A refrigerant passage is formed through connecting sections. The heat exchange tubes are arranged alternately between the heat exchanger cores to avoid liquid distributors and gas collection manifolds. The heat exchange efficiency is improved by utilizing the incoming air. The multi-row bending design mixes the air temperature and refrigerant state, optimizing the heat exchange effect.
It improves heat exchange efficiency, avoids condensate buildup and blowout problems, enhances the end-customer experience, reduces production costs, and increases product qualification rate.
