Abstract

The invention discloses a thermal management system for an engine and an engineering machine. The thermal management system comprises a heat radiator, a fan, a sealed engine compartment, a first temperature detecting device and / or a second temperature detecting device, an opening regulating mechanism and a control unit, wherein the engine and the fan are arranged in the engine compartment; the engine compartment is provided with a controllable air outlet; the control unit is used for controlling the rotation speed state of the fan according to first temperature information output by the first temperature detecting device and the second temperature information output by the second temperature detecting device and / or controlling the opening state of the controllable air outlet by virtue of the opening regulating mechanism so as to enable the engine to be in a preset temperature range. A closed loop mode is adopted for combining heat dissipation of the fan and heat dissipation of an internal flow field of the engine compartment to manage the heat dissipation of the engine, so as to adapt to heat dissipation or heat engine demands of various engine operating conditions in different climatic environments, and power loss can be reduced while the engine can be in the preset temperature range.

Description

technical field [0001] The invention relates to the technical field of engine thermal management, in particular to a thermal management system for an engine and engineering machinery. Background technique [0002] At present, construction machinery is widely used in roads, bridges, urban construction, wind turbine shipment, and petrochemical infrastructure. Since construction machinery often works in harsh environments, the market has higher and higher requirements for the environmental adaptability of construction machinery. Among them, the adaptability of construction machinery engines to various temperature environments is an important aspect. At present, it is generally required that construction machinery engines can still work normally in working environments above 40°C above zero and below 20°C below zero. [0003] In the prior art, the engine heat dissipation system on construction machinery generally includes radiators, fans, thermostats, circulation pumps, etc. Dur...
