Surface Condenser(Water Cooled Condenser):

A surface condenser is a type of heat exchanger used in power plants, industrial processes, and refrigeration systems to condense steam or other vapours into a liquid. It is called a "surface" condenser because the condensation process takes place on the external surfaces of tubes or plates, as opposed to an internal condenser where the condensation occurs inside the tubes or passages.

In a surface condenser, steam or vapor is brought into contact with a series of tubes or plates that are cooled by a separate cooling medium, water. The cooling medium absorbs the heat from the steam or vapor, causing it to condense into a liquid. The condensed liquid is then collected and typically returned to the boiler or used for other purposes, such as for industrial processes or as a water source.
