AI Technical Summary

Technical Problem

Existing heat exchangers cannot achieve optimal performance in both cooling and heating modes because the flow path design cannot be optimized under different operating conditions, resulting in insufficient overall efficiency.

Method used

Design a heat exchanger that employs multiple heat exchange flow paths and flow splitting components, including first and second flow paths. By controlling the unidirectional flow of fluid between different flow paths through a Tesla valve, flow path switching between cooling and heating modes can be achieved, thereby improving overall efficiency.

Benefits of technology

By flexibly switching the flow path, the performance of the heat exchanger under different operating conditions is improved, the cooling and heating efficiency of the air conditioner is increased, and the pressure drop loss and maintenance costs of the system are reduced.
