A flow-through fluid heater comprises: a high thermal conductivity conduit-defining body shaped to provide a conduit that extends between an inlet port and an outlet port; one or more heating elements connected to the body for providing heat to the body, thereby permitting the body to provide heat to fluid flowing through the conduit; a temperature sensor connected to sense a measured temperature indicative of a temperature of the fluid in a vicinity of the temperature sensor; one or more flow rate sensors for sensing a measured flow rate of the fluid through the conduit; and a controller connected to receive signals from the temperature sensor and the flow rate sensors, the controller configured to control an amount of heat energy imparted to the fluid during a period that the fluid is resident in the conduit between the inlet port and the outlet port based at least in part on the measured temperature and the measured flow rate.

High thermal transfer flow-through heat exchanger

A flow-through heater for heating a fluid comprises: a high thermal conductivity conduit-defining body shaped to provide, within the conduit-defining body, a helical-shaped or spiral-shaped conduit that extends between an inlet port and an outlet port; and one or more heating elements operatively connected to an exterior of the conduit-defining body for providing heat to the conduit-defining body and to any fluid flowing through the conduit. Because of the high thermal conductivity of the conduit-defining body, all of the surfaces of the conduit-defining body that actually define the conduit contribute significantly to heating the fluid in the conduit. Each conduit-defining surface may contribute to heating the fluid in approximately equal proportion to its conduit-defining surface area.
