Abstract

The invention discloses an engine cooling system with a sand trap. The engine cooling system comprises a cylinder body water jacket, a cylinder cover water jacket and a water pump. The cylinder body water jacket and the cylinder cover water jacket are connected. A water outlet of the cylinder cover water jacket is connected with a water inlet of a radiator through a thermostat. A water outlet of the radiator is connected with the cylinder body water jacket through a water pump. The sand trap is arranged between a pipeline between the water outlet of the cylinder cover water jacket and the water inlet of the thermostat. The upper end of the sand trap is communicated with the pipeline. When cooling liquid enters the pipeline, the cooling liquid containing cylinder cover type sand granule impurities enters the thermostat after passing through the sand trap, and vortex produced through the sand trap enables the cylinder cover type sand granule impurities in the cooling liquid to be deposited at the bottom of the sand trap; then, when an engine is maintained, the bottom of the sand trap is detached to be cleaned, and after cleaning is finished, the bottom of the sand trap is installed, and cooling liquid is added into the engine. The engine cooling system is low in energy consumption, easy and convenient to disassemble and maintain, simple in structure, low in cost and easy to maintain.

Description

technical field [0001] The invention relates to a vehicle engine cooling system, in particular to an engine cooling system with a grit chamber and a control method thereof, which is mainly suitable for reducing particle impurities in the vehicle engine cooling system and protecting the components of the cooling system. Background technique [0002] With the rapid development of the economy, the number of vehicles is increasing. The residual molding sand in the engine cylinder head has a great impact on the reliability and service life of the cooling system components. However, at present, there are few special methods used in the engine cooling system to solve the problem of excessive particulate impurities in the system. Even for a few engines with filter devices, most of them directly use traditional filter media for filtration. The method not only has complicated process and high cost, but also is difficult to arrange so that the particulate impurities can be removed at ...
