Cooling system for a prime mover

A prime mover, said prime mover comprising:

• a housing;
• at least one mechanical component positioned within said housing of said prime mover, said at least one mechanical component converts one of energy to useful work and useful work to energy;
• and
• at least one cooling jacket defined within said housing of said prime mover and defined around said at least one mechanical component, the at least one cooling jacket comprises an inlet and an outlet, the inlet of the at least one cooling jacket receives refrigerant in a substantially liquid state at a low temperature, wherein the refrigerant in the substantially liquid state at the low temperature that is received through the inlet of the at least one cooling jacket flows past said at least one mechanical component positioned within the at least one cooling jacket to cool said at least one mechanical component positioned within the at least one cooling jacket, wherein the refrigerant is therein delivered through the outlet of the at least one cooling jacket in a substantially gaseous state at a high temperature due to absorption of heat by the refrigerant from said at least one mechanical component positioned within the at least one cooling jacket.

A method of assembling a prime mover, the method comprising:

• positioning at least one mechanical component within a housing of the prime mover, wherein the at least one mechanical component converts one of energy to useful work and useful work to energy;
• defining at least one cooling jacket within the housing of the prime mover and defined around the at least one mechanical component, the at least one cooling jacket comprising an inlet and an outlet;
• channeling refrigerant in a substantially liquid state at a low temperature through the inlet of the at least one cooling jacket such that the refrigerant that is channeled in the substantially liquid state at the low temperature through the inlet of the at least one cooling jacket flows past the at least one mechanical component positioned within the at least one cooling jacket to cool the at least one mechanical component positioned within the at least one cooling jacket;
• and
• delivering refrigerant that flows past the at least one mechanical component positioned within the at least one cooling jacket to cool the at least one mechanical component positioned within the at least one cooling jacket through the outlet of the at least one cooling jacket in a substantially gaseous state at a high temperature due to absorption of heat by the refrigerant from the at least one mechanical component positioned within the at least one cooling jacket.
