A thermal management system for an engineering vehicle and an articulated dump truck

Abstract

A thermal management system for an engineering vehicle and an articulated dump truck. The thermal management system includes a heating element, a cooling element, a heating element, and a monitoring element; the heating element includes an engine, a gearbox, a transfer case, a front axle, a middle axle, and a rear axle. Bridge; cooling elements include a first radiator, a first fan, a second radiator, a second fan, a first heat exchanger, a second heat exchanger, a cooler and an expansion tank; heating elements include a cab and a urea tank; The monitoring components include temperature sensor Ⅰ, temperature sensor Ⅱ, temperature sensor Ⅲ and temperature sensor Ⅳ; among them, the heating element, heating element, and heat dissipation element are connected with multiple interrelated circuits through pipelines, and cooling water or oil flows in the pipeline to form a Multiple cooling circuits, and adjust the heat dissipation capacity of the system through the temperature signals monitored by the monitoring components, so as to form the thermal management system of the whole machine and realize unified management, which can effectively reduce energy consumption, reduce noise, and improve cooling efficiency.

Description

technical field [0001] The invention relates to a thermal management system for a whole machine of an engineering vehicle, which belongs to the technical field of engineering machinery. Background technique [0002] The articulated dump truck has two front and rear frames. The front frame is equipped with power source and control center, and the rear frame is equipped with cargo components. The front and rear frames are connected by hinges, and the front and rear frames can realize relative Turning and tilting greatly reduces the torsional bending deformation of the frame and reduces the turning radius. Articulated dump trucks are widely used in small mining areas with limited space, rainy, muddy and rugged roads. [0003] The engine, gearbox, transfer case, cab, hydraulic system, electrical system and other components of the articulated dump truck are all installed on the front frame, resulting in a particularly compact layout of the front vehicle, which affects the heat d...

AI Technical Summary

Problems solved by technology

[0003] The engine, gearbox, transfer case, cab, hydraulic system, electrical system and other components of the articulated dump truck are all installed on the front frame, resulting in a particularly compact layout of the front vehicle, which affects the heat dissipation effect. Prone to high temperature alarm, affecting the normal operation of the vehicle

In addition, the existing heat dissipation of each component is independent heat dissipation, and each heating unit is equipped with a set of heat dissipation system. The heat dissipation unit is making noise, and the whole machine is noisy
