Two-chamber expansion tank for armored vehicle cooling system

Abstract

The invention belongs to the technical field of water cooling, and relates to an expansion water tank for an armored vehicle cooling system. The water tank is divided into two chambers, the steam chamber and the cooling liquid chamber, by a sealed partition. The two chambers are independent and sealed, and communicate with each other through a connecting pipe. The volume of the steam chamber is 1% of the total volume of the entire expansion tank. / 3; The steam air valve is installed on the top of the steam chamber, the coolant filling screw plug is installed on the top of the cooling chamber, two reinforcement plates are respectively installed on the coolant chamber and the steam chamber, the drain plug is installed on the bottom of the steam chamber, and the coolant filling plug is installed on the top of the cooling chamber. The connection pipe is located at the bottom of the coolant chamber, and the steam connection pipe is located on the upper part of the side plate of the coolant chamber. The invention has the advantages of reducing the requirements on the layout of the entire vehicle under the premise of satisfying the normal operation of the expansion tank, and providing a technical basis and guarantee for the military armored vehicle to realize high power density.

Description

technical field [0001] The invention belongs to the technical field of water cooling, and relates to an expansion water tank for an armored vehicle cooling system. Background technique [0002] The structure of the expansion tank commonly used in various modern vehicles is composed of an inner cavity, and the cooling water and the steam generated during the system work live together in the same room; the cooling system of tracked armored vehicles such as Type 59, Type 69, and Type 80 and general civilian vehicles There is no independent water expansion tank in the design, and the expansion space of the entire cooling system is formed by using a certain space on the upper part of the water radiator. [0003] The power and transmission of the vehicle will generate a certain amount of heat under normal working conditions. The heat is mainly dissipated through the coolant in the cooling system. As the temperature of the coolant rises, the system must be accompanied by high-tempe...
