AI Technical Summary

Technical Problem

In existing power machinery, radiators are at risk of overpressure when faced with changes in oil temperature and pressure peaks. Furthermore, traditional overpressure bypass valves are complex in structure, occupy a large space, and are difficult to optimize oil flow and heat exchange efficiency.

Method used

The heat exchange equipment includes a pilot-operated valve and an electronic control module. Temperature and pressure sensors monitor the flow in real time, and the electronic control module manages the fluid flow, enabling flexible distribution of the fluid between the heat dissipation path and the discharge path, reducing the risk of overpressure and optimizing heat exchange.

Benefits of technology

Effective management of radiator heat power and temperature reduces overpressure risk, optimizes heat exchange efficiency, reduces radiator thickness and external valve space requirements, and improves system reliability and flexibility.
