Cooling and Heating

Expansion Tank

An expansion tank or reservoir tank is a component commonly used in a vehicle's cooling system that regulates the water level and pressure to keep the engine running at optimum temperature.

1. Material: Reservoir tanks are usually made of plastic (such as polyethylene, polypropylene) or metal (such as aluminum). Plastic tanks are lightweight and corrosion resistant, while metal tanks can be durable and have high thermal conductivity.

2. Size and capacity: The size of the reservoir varies depending on the vehicle's cooling system and engine specifications. The capacity of the tank can vary, typically ranging from a few liters to tens of liters.

3. Shape and design: Reservoir water tanks are usually cylindrical or rectangular in shape and designed to fit around the engine area. The design of these tanks ensures proper placement and installation in the engine area of the vehicle.

4. Pressure Capacity: The tank should be designed to withstand the water pressure within the cooling system.

5. Inlet and outlet points: The reservoir has inlet and outlet points that are integrated with the cooling system. These points provide connections from the tank to the cooling system and radiator.

6. Level Gauge: Some tanks may have a level indicator to show the water level inside. This allows the operator to easily check the water level.

7. Ease of Installation: The reservoir tank should be easy to install in the cooling system. Designs that simplify installation can facilitate service and maintenance.

8. Durability and Corrosion Resistance: Because the reservoir is exposed to a mixture of water and antifreeze, it must be durable and corrosion resistant.
