• Buffering effect: the expansion tank can play a buffering role when the pressure changes slightly.
• Using the physical characteristics of liquid expanding with heat and contracting with cold, the volume expansion phenomenon caused by the expansion of coolant is stored and released, and the normal working state of engine cooling system is maintained.
• The automobile expansion pot is connected with the cooling system through the introduction pipeline at its upper part. When the coolant level drops, new coolant will be pumped from the expansion pot to keep the coolant level in the system.
• It is used to store coolant. When the whole vehicle is started in a large cycle, the coolant in the cooling system will rise in temperature, expand and increase in pressure, and the coolant needs to be released. At this time, the coolant will enter the expansion tank through the overflow pipe for storage.
• Control the pressure of cooling system to avoid excessive pressure. When the coolant expands to a certain extent, the pressure regulating valve located in the coolant expansion tank cover will open, allowing part of the coolant to flow out of the cooling system, so as to achieve the purpose of pressure relief.
