Abstract
A pump assembly such as a centrifugal pump assembly includes a lantern arranged between a pump housing and a motor housing. Surface enlarging elements are arranged at the lantern for increasing heat dissipation and/or enhancing cooling air flow.
Claims12
A pump arrangement, comprising:
- a pump casing;
- a fan impeller;
- a motor casing;
- and
- a lantern having a first part that contacts the pump casing and a second part that contacts the motor casing;
- wherein
- the lantern has heat dissipating surface-enlarging elements that extend farther along a radially-outward direction of the lantern than the first and second parts, wherein
- the motor casing has cooling ribs which cooperate with the heat dissipating surface-enlarging elements of the lantern in such a way that:
- i) both the cooling ribs and the heat dissipating surface-enlarging elements each comprise portions that extend at least partially in the same direction, and ii) a stream of cooling air generated by the fan impeller flows successively over the cooling ribs of the motor casing and the heat dissipating surface-enlarging elements of the lantern.
