Heat Exchanger replacement
Sorry for video quality, these were some of my first ones. Here we are replacing the heat exchanger on a northern lights generator. The heat exchanger is a raw water system (aka salt water). The sometimes rapid change of sea temperature can cause the cooper nickel piping to cause sudden leaks.
The heat exchanger is the sphere shaped object in the video. Inside there are about 20 tubes, looks like a honey combs from each end with the caps off. Every other tube has coolant and the other has salt water running through them. The cold sea water is used to cool the coolant enough to keep the engine from over heating.
This process is formed from causing the surface temperature of the saltwater pipes cooling the surface temperature of the coolant pipes.
The reason for replacement: We received a high bilge alarm while at anchor in the Caribbean at around 11pm. I quickly rushed to the engine room to find a massive leak in our heat changer on our port generator. Luckily we had two back up generators onboard that vessel.

A place to discuss boat’s and all their fabulous design flaws that us “engineers” get to fix and repair.
