Abstract
The present invention provides a cooling pump, an electronic apparatus, and a cooling system in which positioning between a heat generating unit and a cooling pump can be achieved easily. The cooling pump according to the invention includes: a rotor having a disk-shaped member fixed to a revolving shaft, impellers for pressurizing liquid coolant provided on the disk-shaped member, a plurality of permanent magnets disposed into a ring shape disposed on and fixed to the disk-shaped member; a case including a pump chamber for rotatably accommodating rotor, an inlet port and a discharge port for the liquid coolant, and a heat receiving portion for the a heat generating unit which corresponds to part of the side wall of the pump chamber; a cover that closes the case in a liquid-tight manner and is formed with a recess, a stator stored in the recess of the cover for generating revolving magnetic field by a plurality of electromagnets and providing torque about the revolving shaft to the rotor; and a positioning member joined to the heat receiving portion for positioning with respect to the a heat generating unit.
