Abstract

An automobile expansion water tank, comprising a tank body (17), on which two degassing pipe ports (1), a filling port, a liquid level sensor port (5) and a return pipe port (6) are arranged, two Two degassing pipe ports (1) are arranged side by side at the bottom of the box body (17), and a reinforcing rib partition (9) is vertically arranged in the box inner cavity (8), and the reinforcing rib partition (9) is close to the two degassing pipe ports (1 ) side of the outer wall of the box (17), and the rib partition (9) separates the box cavity (8) into two cavities, the pressure relief chamber (10) and the working chamber (18), and the rib partition (9) The upper end is respectively provided with an upper pressure relief hole (12) and a lower pressure relief hole (19). The upper pressure relief hole (12) and the lower pressure relief hole (19) are distributed along the vertical direction. (1) Connected. Have avoided the overflow of the cooling fluid that the internal pressure of casing (17) is excessively caused? "Backwater" phenomenon.

Description

technical field [0001] The invention relates to an expansion water tank, in particular to an automobile expansion water tank, and belongs to the technical field of components used in automobile engine cooling systems. Background technique [0002] The automobile expansion water tank is a part of the automobile cooling system. Its function is to ensure the normal operation of the engine cooling system under a certain working pressure, and prevent the residual air in the cooling system from participating in the cooling water circulation, causing cavitation damage to the engine water jacket and water pump; At the same time, the expansion tank can also reduce the loss of coolant. The automobile expansion water tank has the following three functions: 1. Fill and compensate the coolant for the engine; 2. Release pressure, condense and separate the high-temperature and high-pressure liquid-gas mixture; 3. Regulate the normal working pressure of the cooling system. [0003] At pres...
