An expansion kettle and its processing method

Abstract

The invention relates to an expansion tank and a treatment method. The expansion tank comprises an expansion tank casing and a tank end cap, wherein the inside of the expansion tank casing is divided into a first cavity and a second cavity by a partition board; an injection port, a pressure cap, a cooler exhaust water pipe connector, an engine exhaust water pipe connector, an engine water-replenishing pipe connector, a pressure relief guide pipe, an exhaust guide pipe and an embedded core are arranged on the tank end cap. According to the technical scheme, the two cavities and one embedded core are arranged in the expansion tank casing, so that iron rust, water scale and bubbles produced during working of a cooling system are absorbed under the action of primary physical absorption and isolation and secondary and tertiary chemical functions, potential threats such as calcium, magnesium and iron ions, acid ions and the like are treated through reactions, the pH value of a cooling liquid is kept constant, the clean and safe cooling liquid is output to the system, the cooling system can operate safely, lastingly and efficiently, and the fault rate and the use cost of a whole vehicle 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 ...
