Intelligentized heat management system of propulsion plant

Abstract

The invention discloses an intelligent heat management system for a power equipment, which comprises a plurality of cooling units, an electronic control unit ECU, a fan and a motorized pump, and is characterized in that the ECU can make judgment depending upon the feedback signal of the temperature of the cooling media, adjust the speed of the fan and the motorized pump, so as to control the operation temperature of the thermal media of each cooling unit to be optimal. The invention realizes the most economic oil consumption by the ECU, guarantees that the engine is always under the optimal operation state under different environments. The advantages with the invention are: 1. The invention can guarantee that the engine is always under the optimal operation condition. 2. The invention can save energy, reduce emission of pollutant, is environmental friendly. 3. Each heat exchanging unit can cool as necessary, no overhot or over cold condition will happen. 4. The intelligent heat management system for power equipments is realized completely depending upon the feedback temperature signal by the ECU.

Description

technical field [0001] The invention relates to an intelligent thermal management system of a power device. It can be widely used in road vehicles powered by internal combustion engines and non-road vehicles such as construction machinery and mining machinery, and can also be used in generator sets, air compressors and other devices. The intelligent thermal management system can include all cooling units in the intercooler, water radiator, oil cooler, torque converter oil cooler, hydraulic oil cooler, EGR cooler and air conditioning condenser, or only a few of them cooling unit. Background technique [0002] In the design of the thermal management systems of various power plants at present, the goal is usually to meet the heat dissipation under the limit state. However, the extreme high temperature environment occurs for a relatively short time, so in most of the working hours, the heat dissipated by each unit of the engine thermal management system usually exceeds the nor...

Problems solved by technology

However, the extreme high temperature environment occurs for a relatively short time, so in most of the working hours, the heat dissipated by each unit of the engine thermal management system usually exceeds the normal demand, resulting in energy waste and greatly increased fuel consumption, which is less beneficial to the normal operation of the engine many disadvantages
