Box Cooler

Box cooler is to achieve the aim to save fresh water by setting up fresh water apparatus outside (or inside)

the shell plate below the shipping waterline, carrying off the heat quantity of the hot fresh water in the

apparatus, due to the difference in temperature between hot cooling water and water outside the

shipboard, and the relative velocity between the water outside the ship and the ship while the ship is on

the way.

Box cooler utilizes the water outside the shipboard for cooling directly, saving water pump (or sea water

pump), and also saving the power consumption of the driving water pump and the inlet valve bilge and

some relative cleaner, simplifying cooling system, lowing making cost.
