Oil Cooler Water Cooling
Tube Heat Exchanger for Industrial Refrigeration
The oil cooler is a heat exchanger that uses air to cool the hot
fluid. And other coolers, there will be rust,
rust occurs mainly because the cooling water contains a lot of
calcium, magnesium ions and acid
carbonate, when the cooling water flows through the metal surface,
it will produce carbonate; Oxygen in
the cooling water also causes the metal to rust to form rust.
When it produces rust after the heat transfer effect will decline,
serious will block the tube so that the heat
loss effect, want to achieve the cooling effect in the shell spray
And as the sediment continues to increase, it will also increase
the cost of energy, because as long as a
thin layer of scale will increase the fouling part of the equipment
operating costs of more than 40%, so the
impact of scaling on heat transfer is huge of.
First, the characteristics:
1, water-cooled oil cooler using water as a medium and oil for heat
exchange, the advantage is better
cooling effect, to meet the relatively low oil temperature
requirements (the oil temperature can be reduced
to about 40 ℃, the disadvantage is that there must be in the water
Of the place to use.
2, air-cooled oil cooler using air as a medium and oil for heat
exchange, the advantage is to air as a
cooling source, basically not limited to the use of places, and
environmental protection, the disadvantage
is due to the impact of ambient temperature, the higher the
temperature , The oil temperature can not be
reduced to the desired temperature (air cooling is generally
difficult to reduce the oil temperature only
higher than the ambient temperature of 5 ~ 10 ℃).
