Patent ID: 8137146

Claim:
A closed loop fluid cooling system for marine motors, comprising: a motor cooling circuit in fluidic communication with fluid cooling jackets proximate to a motor; a heat dissipation circuit; the motor cooling circuit in closed fluidic communication with the heat dissipation circuit; a cooling fluid that circulates between the motor cooling circuit and the heat dissipation circuit; a heat dissipation member in fluidic communication with the heat dissipation circuit to receive the circulating cooling fluid, and the heat dissipation member submerged in a body of water to transfer heat from the cooling fluid to the body of water; a temperature control valve in fluidic communication with the motor cooling circuit and the heat dissipation circuit; and the temperature control valve connects the motor cooling circuit and the heat dissipation circuit in response to a temperature change of the cooling fluid or the motor to provide for the circulation of the cooling fluid between the motor cooling circuit and the heat dissipation circuit.
