Abstract

An expansion tank of an automobile comprises a tank body (17). The tank body (17) is provided with two air removing pipe ports (1), an injection port, a liquid-level sensor connector (5) and a water returning pipe port (6). The two air removing pipe ports (1) are formed in the bottom of the tank body (17) side by side. A reinforcing rib separation portion (9) is vertically arranged in a tank body cavity (8) and is close to the outer wall of the edges, except for the sides with the two air removing pipe ports (1), of the tank body (17). The tank body cavity (8) is divided into a pressure-releasing cavity (10) and a working cavity (18) through the reinforcing rib separation portion (9). An upper pressure-releasing hole (12) and a lower pressure-releasing hole (19) are respectively formed in the upper end of the reinforcing rib separation portion (9) and are vertically distributed. The pressure-releasing cavity (10) is communicated with the two air-removing pipe ports (1). The cooling liquid overflowing and water-returning phenomenon caused by overlarge internal pressure of the tank body (17) is avoided.

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...
