A kind of expansion kettle and processing method

Abstract

The invention relates to an expansion tank and a processing method. The expansion tank comprises an expansion tank shell which is divided into a first cavity and a second cavity by a partition plate. The expansion tank shell is provided with a filling port, a pressure cover, a radiator exhaust water pipe connector, an engine exhaust water pipe connector, an engine water supplementing pipe connector, a pressure relief guide pipe, an exhaust guide pipe and an internal core. According to the technical scheme, through the two cavities and the internal core in the expansion tank shell as well as first-stage physical absorption and isolation, and second-stage and third-stage chemical action, iron rust, water scale and bubbles generated during operation of a cooling system are absorbed, a reaction is carried out, potential threats including calcium and magnesium ions, iron ions and acid ions are handled, constancy of the PH value of a cooling solution is maintained, the clean and safe cooling solution is output to the system, therefore the effect that the cooling system operates safely, durably and efficiently is ensured, and the failure rate of a finished vehicle and the vehicle usage cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of engine cooling systems, in particular to an expansion kettle and a processing method. Background technique [0002] According to a survey, more than 50% of car engine failures in the world come from the cooling system. When the engine is working, it will generate a lot of heat. When the engine temperature is too high, its efficiency will be reduced, and even parts will fail. A car's cooling system circulates fluid through pipes and passages in the engine. When the fluid flows through the high-temperature engine, it will absorb heat, reduce the temperature of the engine, and provide an appropriate temperature to ensure that the engine is at a suitable operating temperature. After the liquid flows through the engine, it turns to the heat exchanger (radiator), through which the heat in the liquid is dissipated into the air. However, after the car has been used for a period of time, fuel consumption often ...
