AI Technical Summary

Technical Problem

The cooling fan speed of mining dump trucks is linked to the engine speed in a fixed ratio, and cannot be dynamically adjusted to meet the cooling demand, resulting in insufficient heat dissipation under high temperature conditions and energy waste under low temperature conditions.

Method used

A hydraulic motor drives the cooling fan, and a temperature sensor and controller are used to dynamically adjust the displacement of the oil pump to regulate the speed of the cooling fan. The oil supply device and control components are used to detect and regulate the temperature of the engine coolant and hydraulic oil.

Benefits of technology

It improves heat dissipation efficiency, reduces energy consumption and noise, and enhances the stability and reliability of the heat dissipation system.

Abstract

This application discloses a cooling system for vehicles and a mining engineering vehicle. The cooling system for vehicles includes an oil supply device, a cooling device, and a control component. The oil supply device includes an oil tank and a drive oil pump. The oil inlet of the drive oil pump is connected to the oil tank, and the drive oil pump is also equipped with a displacement adjustment component. The cooling device includes a hydraulic motor and a cooling fan. The first and second working oil ports of the hydraulic motor are respectively connected to the oil outlet of the drive oil pump and the oil tank. The drive end of the hydraulic motor is connected to the cooling fan. The control component includes a controller and a first temperature sensor for detecting the engine coolant temperature. The controller is communicatively connected to the adjustment component and the first temperature sensor, and is used to adjust the adjustment component according to the detection data of the first temperature sensor to dynamically adjust the speed of the cooling fan.
