Abstract
This article presents an analysis of the cooling system for water jacket electrical machined using seawater as a refrigerant. In this system, the water circulates through channels inside the machine transferring the heat generated by the active part to the external environment. Water-cooled electrical machined have been developed for use in space-constrained installations, with a compact design is commonly used in boats. The use of seawater as refrigerant in this case is an interesting alternative, eliminating the use of cooling towers and treatment of water in the boat. Therefore, it is possible to reduce the water storage, increase the space available and reducing the investments considerably. However, the use of seawater for cooling is always critical, due to the problems related to increase of corrosion and incrustation. This work will present the study of two protection alternatives that will reduce the effects of corrosion and incrustation in a cooling system of electrical machined cooled with seawater. For this, two prototypes were prepared and those submitted to the test that simulates the operation condition of the water jacket electrical machined. After the test, the samples were analyzed to understand the effects of corrosion and incrustation in the different protection alternatives.
