Abstract

The invention relates to the technical field of engineering power machines, in particular to a thermostatic heat management power machine cooling system. An air intake intercooler and a cooling liquid cooler are mounted in series, and a cooling fan is mounted on one side, close to the air intake intercooler, of the an engineering power machine. Through the arrangement that the intercooler and the cooling liquid cooler are mounted in series in a front-back manner, the fan mounted at the front end of the intercooler blows air towards the intercooler and the cooling liquid cooler to cool the same. Temperature sensors mounted on a water inlet and a water outlet of the power machine are used for monitoring an intake air temperature value and an outlet water temperature value; when the temperature values are lower than a required lower temperature limit, temperature controllers control a temperature-control electronic proportional valve on a bypass air pipe to be turned on according to temperature departure states to raise the temperature; when one temperature value is over an upper limiter, the corresponding temperature controller controls an electronic clutch to enable the fan to run so as to increase cooling air volume. Through control on different working conditions, the cooling liquid temperature and the boosting air intake temperature are kept within a required temperature range constantly, and thermostatic heat management on the power machine cooling system is realized.

Description

technical field [0001] The invention relates to the technical field of engineering power machines, in particular to a cooling system capable of performing constant temperature heat management on the cooling system of engineering power machines. Background technique [0002] At present, the known engineering power machine cooling system, through the rotation of the fan connected to the engine pulley, forms a cooling wind, blows through the cooling water tank and the intercooler connected in series or in parallel, and radiates heat to the cooling liquid of the power machine and the supercharged air intake. . Because the temperature control requirements of the power engine coolant are contrary to the temperature control requirements for the supercharged intake air of the power engine: the temperature of the coolant is required to be controlled between 92-97 degrees, and the closer the temperature is to the upper limit, the performance of the engine and fuel economy will be affe...
