AI Technical Summary

Technical Problem

The existing temperature controller is installed at the water inlet of the radiator. Due to the heat from the heat sink, the temperature control accuracy is inaccurate. Moreover, the installation is complicated and easy to cause burns. In addition, the traditional installation method is inconvenient.

Method used

The design incorporates an external, quick-connect temperature control head with the sensor and regulator separate. The sensor is located away from the heat source and connected to a bellows via a capillary tube. The temperature-sensing liquid controls the valve stem opening, and the device is quickly installed using a custom-shaped platform and a torsion spring.

Benefits of technology

It improves temperature control accuracy, avoids the risk of burns from high temperatures, and enables a fast and reliable installation process.

Abstract

A quick-connect temperature controller with an external temperature sensor includes a separate temperature sensor and a regulator. The regulator includes a housing connected to a temperature control valve, with a bellows inside the housing. The upper end of the bellows contacts a fixed component. A sleeve is provided at the bottom of the housing, with a first through-hole on the sleeve and a second through-hole at the bottom of the housing. The housing is connected to the valve body of the temperature control valve via a connecting cap. This invention, on the one hand, places the temperature regulator externally to keep it away from heat sources, ensuring the ambient temperature sensed by the thermometer is maintained. It also connects to the bellows via a capillary tube, thereby controlling the opening degree of the temperature control valve to achieve a proportional opening or closing effect. On the other hand, the rotating connecting cap allows for quick installation onto the valve body of the temperature control valve, preventing burns from contact with the valve body during operation.
