Tube type heat exchanger with motor or generator housing

A cooling assembly for an electromechanical device, the assembly comprising:

• a housing having a wall portion;
• a magnetic field member disposed within said housing and arranged adjacent said wall portion;
• a shaft having windings located within said magnetic field member with an electrical current flowing through said windings coacting with said magnetic field member, wherein at least one of said magnetic field member and said windings produces heat;
• and
• a helical cooling coil defining a fluid conduit arranged adjacent said magnetic field member for removing said heat, wherein said wall portion is disposed between said coil and said windings with said coils secured to said wall portion.

A method of cooling an electromechanical device comprising the steps of:

• a) producing heat in the electromechanical device having a temperature;
• b) pumping fluid through a helical coil arranged about a portion of the electromechanical device;
• and
• c) absorbing the heat in the fluid to reduce the temperature.
