Abstract
A fluid heater system for a pumping system comprises a core, a heating element and a sleeve. The core comprises a body made of thermally conductive material, and a plurality of channels formed on an outer periphery of the body. The heating element is disposed within the core. The sleeve surrounds the core adjacent the plurality of channels. The sleeve is formed of a material having a higher strength than the thermally conductive material of the core. In another embodiment, the plurality of channels is chamfered to form a portion of a common outlet plenum and the core includes a temperature sensor bore located proximate the common outlet plenum.
Claims21
A fluid heater system comprising:
- a core comprising:
- a body made of thermally conductive material;
- and
- a plurality of channels formed on an outer periphery of the body;
- a heating element disposed within the core;
- and
- a sleeve surrounding the core adjacent the plurality of channels;
- wherein the sleeve is formed of a material having a higher strength than the thermally conductive material of the core.
A fluid heater core comprising:
- an elongate flow section extending from an inlet end to an outlet end;
- a plurality of parallel, spiral flow channels disposed in the elongate flow section extending between the inlet end and the outlet end;
- a first chamfer of the plurality of parallel, spiral flow channels at the inlet end;
- and
- a second chamfer of the plurality of parallel, spiral flow channels at the outlet end;
- wherein the fluid heater core is fabricated from an aluminum alloy.
