Description
The coolant is pumped through the engine, then after absorbing the
heat of combustion is circulated to the radiator where the heat is
transferred to the atmosphere. The cooled liquid is then
transferred back into the engine to repeat the process.
This Cooling system has four types of systems:
Direct Or Non-Return System
Thermo - Syphone System
Hopper System
Pump / Forced Circulation System
Direct or Non-Return Water Cooling System:
This is suitable for large installations and where plenty of water
is available. The water from a storage tank is directly supplied to
the engine cylinder. The hot water is not cooled for reuse but
simply discharges. The low H.P. engine, coupled with the irrigation
pump is an example.
Thermo-Syphone Water Cooling System:
This system works on the principle that hot water being lighter
rises up and the cold water being heavier goes down. In this system
the radiator is placed at a higher level than the engine for the
easy flow of water towards the engine. Heat is conducted to the
water jackets from where it is taken away due to convection by the
circulating water. As the water jacket becomes hot, it rises to the
top of the radiator. Cold water from the radiator takes the place
of the rising hot water and in this way a circulation of water is
set up m the system. This helps in keeping the engine at working
temperature.
Hopper Water Cooling System:
This also works on the same principle as the thermo-syphone system.
In this there is a hopper on a jacket containing water, which
surrounds the engine cylinder.
In this system, as soon as water starts boiling, it is replaced by
cold water. An engine fitted with this system cannot run for
several hours without it being refilled with water.
