Abstract

The invention discloses a hydraulic oil temperature control device and an engineering device and relates to the technical field of engineering machinery. The technical problem that a hydraulic execution component is low in operation efficiency when a hydraulic system is in a low-temperature environment in the prior art is solved. The hydraulic oil temperature control device comprises a thermal energy transmitting device and a thermal energy exchange device, the thermal energy transmitting device is respectively connected with the thermal energy exchange device and a heat source, and the heat source enables thermal energy released by the heat source to be transmitted to the thermal energy exchange device through the thermal energy transmitting device, the thermal energy exchange device is connected with a hydraulic oil tank, and the thermal energy exchange device can transmit the thermal energy to the hydraulic oil tank. The engineering device comprises an oil pump, the hydraulic execution component, the hydraulic oil tank and the hydraulic oil temperature control device. The hydraulic oil temperature control device is used for improving operation efficiency of the hydraulic execution component in the low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a hydraulic oil temperature control device and a construction machine equipped with the hydraulic oil temperature control device. Background technique [0002] Construction machinery is a general term for construction machinery used in engineering construction. The hydraulic system is one of the important components of most construction machinery. The hydraulic system refers to a transmission system that uses liquid as the working medium to transmit and control energy. [0003] At present, with the advancement of modernization in my country and even the world, most countries and regions are carrying out engineering construction throughout the year. This requires that the hydraulic system of the construction machinery complete machine (the complete machine refers to a complete set or a single, single-unit form of electromechanical products, hereinafter referred to...
