The Plate Cooler is the most simple structure heat exchanger, it consists of the thin plate with attached rubber gasket and it enables heat exchanger in a short time by using two fluid let flows between narrow gaps because the corrugation of the thin plate easily forms turbulent flow in the very low Reynolds number, the heat transfer coefficient of two kinds of liquid is generally 2~4 times larger than the heat exchanger of tubular type and heat exchange is efficient due to counter flow. Furthermore, plate cooler is very ideal heat exchanger even in the temperature higher than 1¡É contrary to tubular type whose temperature approach is over 4¡É. In addition, it is one of the most important machines in the ship because it makes Main Engine, Generator Engine and other auxiliary machine exchange heat as only one plate cooler.
DongHwa-LHE advantages
[Plate Design]
We have various plate & thermal length.
So, we can design more compact.
The heat plate forms corrugation to maximize the heat transfer efficiency and chevrons to create turbulence flow also designed to make countercurrent flow which enables to diminish the quantity of fluid remaining in the heat exchanger and eliminate the dead-zone. The plate heat exchanger can obtain five times heat transfer efficiency compared with shell and tube heat exchange.
Even Fluid Distribution
Plate Inside Velocity
V1 = V2 = V3 = V4
¡à Minimized Dead Zone
¡à Minimized Fouling
¡à Increased Durability
Improved Wave Pattern
¡à Minimized Dead Zone
¡à Minimized Fatigue Stress
¡à Increased Strength of Structure
¡à Increased Durability & Anti-Corrosion
Outstanding Sealing for Performance
The gasket can be fixed tightly and quickly on the heat plate in the optimum condition with the dual fixing device(snap on type), and is designed and manufactured to have the glue and non-glue type so that it can be selected according to the usage.
