Abstract
An ultra-thin pump of the present invention includes a ring-shaped impeller including many vanes arranged along its outer region and a rotor magnet at its inner region, a motor stator provided in a space encircled by an inner peripheral surface of the rotor magnet of the impeller, and a pump casing that includes a suction port, a discharge port and a cylinder disposed between the motor stator and the rotor magnet and houses the impeller. The impeller is rotatably supported by the cylinder. A cooling system of the present invention includes a cooling device for cooling a heat-producing device by heat exchange using coolant, a radiator for removing heat from the coolant, and the ultra-thin pump for circulating the coolant. The ultra-thin pump is simple in structure, operates efficiently and can be manufactured at low cost, and the cooling system is thin in structure and performs efficient cooling.
