Hydraulic excavator heat dissipation control method and system and hydraulic excavator

Abstract

The invention provides a hydraulic excavator heat dissipation control method and system and a hydraulic excavator. The heat dissipation control method comprises the steps that S1, a plurality of independent heat dissipation modules are arranged for a plurality of heating elements of the hydraulic excavator in a one-to-one correspondence mode; S2, a front-end temperature value and a rear-end temperature value of the heating elements and a target temperature value of the heating elements are acquired; and S3, according to the front-end temperature value, the rear-end temperature value and the target temperature value, the heat dissipation power of a heat dissipation mechanism of the heat dissipation module is adjusted, so that the rear-end temperature value of the heating elements is within a target temperature range. The independent heat dissipation modules are combined with the front end temperature values, the rear end temperature values and the target temperature values of all the heating elements, dynamic and accurate heat dissipation control over the heating elements can be achieved, unnecessary heat dissipation consumption can be avoided, it can be guaranteed that all the heating elements are at the optimal working temperature, and the hydraulic excavator can be reliably operated for a long time.

Description

technical field

[0001] The invention belongs to the technical field of earthwork engineering machinery, and in particular relates to a heat dissipation control method and system of a hydraulic excavator and the hydraulic excavator. Background technique

[0002] Pure battery-driven hydraulic excavators have the advantages of low noise, fast action response, and low cost of use, and have become an important research direction for many manufacturers. But the current difficulty lies in how to ensure that the battery power is used as much as possible and the continuous working time is extended under the premise of limited installation space and limited battery capacity. To solve this problem, we can start from many directions, one of which is to optimize the cooling system. A good heat dissipation system can not only ensure the stable operation of each electrical module, but also prolong its service life. However, the existing heat dissipation system solutions usually use one r...
