Abstract
An example axial pump for delivering liquid coolant to cool an electronic device comprises a conduit defining a flow path from an inlet of the conduit to an outlet of the conduit and an impeller in the conduit. The impeller is rotatable about an axis of rotation parallel to the flow path. The pump also has a motor stator configured to drive rotation of the impeller body about the axis of rotation. In addition, the pump comprises an adjustment mechanism coupling the impeller to the conduit. The adjustment mechanism is actuatable to cause translation of the impeller relative to the conduit. This may allow for adjustment of a clearance between a blade tip of a blade of the impeller and a wall of the conduit.
Claims21
An axial pump for delivering liquid coolant to cool an electronic device, comprising:
- a conduit defining a flow path from an inlet of the conduit to an outlet of the conduit;
- an impeller in the conduit, the impeller comprising:
- a shaft extending parallel to the flow path;
- an impeller body rotatably coupled to the shaft, wherein the impeller body is rotatable relative to the shaft and the conduit about an axis of rotation parallel to the flow path;
- a motor stator configured to drive rotation of the impeller body about the axis of rotation;
- and
- an adjustment mechanism coupling the shaft to the conduit, wherein the adjustment mechanism is actuatable to cause translation of the impeller shaft and the impeller body relative to the conduit.
