Description

A frame fresh water cooler structure

technical field

The invention relates to the field of marine heat exchange equipment, in particular to a frame fresh water cooler structure.

Background technique

At present, many heat exchangers are used on ships to exchange heat from seawater to freshwater circulation. The conventional seawater circulation cooling scheme installs all cooling systems inside the cabin. Although it has certain convenience in maintenance, the larger exchange Equipment such as heaters and circulating water pumps will occupy the interior cabin space. This relatively extensive method occupies a large amount of cabin pipeline space, which is not conducive to the space layout of the ship and is more cumbersome to operate.

Secondly, at present, most marine heat exchangers use plate heat exchangers, and commonly used fresh water coolers usually use plate coolers. Because the equipment requires a certain amount of heat dissipation, maintenance space, and occupies a large location, the process of plate heat exchangers is complicated. The resistance of seawater flowing through the plate is relatively high, and the ability to withstand high pressure is not strong, so leakage is prone to occur. Moreover, the heat dissipation effect depends on the number of plate-cooled titanium plates. Titanium plates are expensive, and the equipment itself dissipates a certain amount of heat, which is not energy-saving and environmentally friendly.
