Abstract: Refrigeration cycle intercooler with dual coil evaporator is a component in a refrigeration cycle that is installed in a vehicle with an internal combustion engine or motor. The refrigeration cycle operates by continuously cycling a refrigerant through a closed loop where refrigerant passes through an inner coil evaporator and an outer coil evaporator where the refrigerant changes from liquid to gas, thereby providing a cooling effect. During operation, fresh air or outside air continuously passes by the inner coil evaporator and the outer coil evaporator and then continues into the internal combustion engine or motor air intake. The inner coil evaporator and the outer coil evaporator function to cool and dry the intake air for the internal combustion engine or motor. The inner coil evaporator and an outer coil evaporator are specially designed to provide substantially more cooling and drying than any other intercooler design.
