AI Technical Summary

Technical Problem

Existing hydraulic oil tanks have limited heat exchange area in the cooler when the oil temperature is too high, resulting in slow heat dissipation and an inability to quickly reduce the oil temperature to a suitable range, affecting the normal operation of the hydraulic system. Furthermore, existing oil temperature regulation systems cannot accurately maintain the oil temperature within the optimal operating temperature range, leading to unstable system pressure and reduced equipment operating accuracy.

Method used

The hydraulic oil tank with integrated oil temperature regulation function achieves real-time monitoring and precise control of oil temperature by setting rectangular guide rails and positioning sliding blocks inside the oil tank, combined with infrared temperature zone sensors, phase change material contact parts and microchannel control components. By using components such as fuzzy controllers and microchannel coolers, cooling and heating strategies are dynamically adjusted to improve heat exchange efficiency and accuracy.

Benefits of technology

It enables rapid and precise adjustment of oil temperature, reduces the number of times the cooler and heater are started, lowers energy consumption, enhances the reliability and durability of the hydraulic system under complex working conditions, ensures that the oil temperature is stable within a suitable range, and improves the operating accuracy of the equipment.

Abstract

This invention discloses a hydraulic oil tank with integrated oil temperature regulation function, relating to the technical field of hydraulic systems for engineering machinery. It includes an oil tank body with a rectangular guide rail installed inside. A paraffin phase change material layer is installed on the inner wall surface of the oil tank body. With the cooperation of a positioning phase change temperature control component and a microchannel control component, an oil temperature sensor feeds back the oil temperature data of the affected area to a fuzzy controller, enabling real-time detection of local temperature differences. A front-end orientation adjustment structure drives the phase change material contact element and the oil temperature sensor to accurately locate abnormal areas, achieving targeted monitoring and regulation of abnormal oil temperatures. Simultaneously, the front-end orientation adjustment structure adjusts the contact state between the phase change material contact element and the paraffin phase change material layer, achieving intelligent collaborative regulation. This effectively reduces the number of times the cooler and heater are started, lowers energy consumption, and improves the adaptability of the oil temperature regulation system to complex working conditions, enhancing the reliability and durability of the hydraulic system.
