When the energy converter is used in engineering, water permeates into energy converter components through the polyurethane coating layer to cause the failure of the energy converter generally through two paths, wherein the first path is direct permeation, the second path is permeation through the joint of the polyurethane coating layer and the metal flange, and the probability of permeation of the energy converter through the joint of the polyurethane coating layer and the metal flange in a seawater high-pressure environment is far greater than that of the direct permeation. Research and demonstration show that under the actual working condition of seawater, a packaging interface is under the action of high hydrostatic pressure, materials on two sides generate certain shearing force due to different deformation, hydrolysis or other actions can cause the failure or degradation of a coupling agent between a polyurethane coating layer and a metal flange, and when the bonding strength of a material on the interface is reduced to be insufficient to resist the shearing force, packaging leakage failure can occur. The invention adds the polyurethane coating layer at the compression joint to achieve the aim of improving the reliability.
