Abstract
An inter-axial inline fluid heater is presented. The inter-axial inline fluid heater includes an outer retaining sheath defining a first area, and an interior flow tube disposed within the outer sheath and capable of having fluid flow therethrough. Further, the interaxial inline fluid heater includes a resistance wire disposed between the interior flow tube and the outer retaining sheath, the resistance wire capable of producing heat for heating a fluid passing through the interior flow tube when power is applied to the resistance wire. Also includes is a dielectric heat transfer material disposed between the interior flow tube and the outer retaining sheath and surrounding at least a portion of the resistance wire.
Claims20
A fast response fluid heater comprising:
- a flow body having an inner surface, a proximal end and a distal end defining an area therein;
- an inlet tube having a first end, a second end, an inner surface and an outer surface, disposed within said flow body and defining a first area, where said first area is the area defined by the interior of said inlet tube;
- a second area defined by the area disposed between the outer surface of said inlet tube and the inner surface of said flow body, where fluid at the distal end of the inlet tube in said first area can freely communicate with fluid at the distal end of the flow body in said second area;
- an inlet orifice disposed within a surface of said flow body, said inlet orifice for allowing fluid communication between the exterior of said flow body and said second area;
- and
- an outlet tube having a first end extending outside said flow body and a second end disposed within said flow body for allowing fluid communication between the exterior of said flow body and said first area;
- and
- a heater element disposed between said inlet tube and said flow body and capable of producing heat for heating a fluid passing in said first area and said second area.
A fast response fluid heater comprising:
- a flow body having a proximal end and a distal and defining an area therein;
- a generally tubular element, having a proximal end and a distal end, disposed within said flow body, defining an exterior flow path having a proximal end and a distal end, and an interior flow path having a proximal end and a distal end, such that a fluid passes singularly along one of said interior flow path and said exterior flow path prior to entering an other one of said interior flow path and said exterior flow path;
- where said exterior flow path is the area disposed between the outside surface of said tubular element and the inner surface of said flow body;
- where said interior flow path is the area defined by the inner surface of said tubular element;
- a heater element disposed in the area disposed between the outside surface of said tubular element and the inner surface of said flow body;
- where said tubular element is inserted through said flow body such that the proximal end of said tubular element is isolated from the flow path and the tubular element has an interior flow section capable of carrying all of a volumetric flow;
- and
- where a fluid near the distal end of the exterior flow path and a fluid near the distal end of the interior flow path can freely communicate.
A method of heating a fluid, which comprises:
- providing a fluid heater with a proximal end and a distal end and with at least a first flow path and a second flow path;
- where said first flow path and said second flow path are each capable of carrying all of a volumetric flow;
- where said first flow path is circumferentially located about said second flow path;
- providing a heater element disposed within said fluid heater that is capable of heating fluid in the first flow path and second flow path;
- and
- causing a fluid to pass singularly along one of said first flow path and said second flow path prior to entering an other one of said first flow path and said second flow path.
