Abstract
Example pump systems having dual-function annular heat exchangers are disclosed. An example pump system to pressurize a fluid within a closed loop transport bus includes a pump to move the fluid, a conduit in fluid connection with the pump, a heat exchanger positioned around at least a portion of the conduit, the heat exchanger to receive a first electrical signal transmitted in a first direction at a first time and a second electrical signal transmitted in a second direction at a second time different from the first time, the second direction opposite the first direction.

1-20. (canceled)
A pump system comprising:
- a pump to move a fluid;
- a conduit in fluid connection with the pump;
- and
- a heat exchanger positioned around a portion of the conduit, the heat exchanger to receive a first electrical signal transmitted in a first direction at a first time and a second electrical signal transmitted in a second direction at a second time different from the first time, the second direction opposite the first direction, wherein the heat exchanger includes an inner annular housing and inner fins extending centripetally from the inner annular housing, wherein the inner annular housing is in contact with an exterior surface of the conduit, the inner fins to extend past an outer perimeter defined by a portion of the exterior surface of the conduit.
A pump system comprising:
- a pump to move a fluid;
- a conduit in fluid connection with the pump;
- and
- a thermoelectric module including an inner annular housing and an outer annular housing, wherein the inner annular housing is in contact with an exterior surface of the conduit, and wherein the thermoelectric module includes outer fins extending radially outward from the outer annular housing.
An apparatus to exchange heat with a fluid, the apparatus comprising:
- an inner annular housing to contact an outer surface of a fluid conduit;
- an outer annular housing positioned around the inner annular housing;
- junctions positioned between the inner annular housing and the outer annular housing, the junctions including metal plates to couple N-type semiconductors to P-type semiconductors, the metal plates to separate the N-type semiconductors and the P-type semiconductors from the inner annular housing and the outer annular housing;
- and
- inner fins extending centripetally from the inner annular housing.
