Abstract
A fluid heater comprises a first elongated cylindrical housing having a first diameter, a first end for heated fluid exit, a second end for fluid entrance, and a longitudinal axis. An elongated cylindrical airflow member is fixedly positioned within the housing and coaxial therewith. The airflow member has a second diameter and has a length less than the length of the housing and terminates before the first end. A heating element has a third diameter and is positioned coaxially within the airflow member and is fixed therein. A baffle tube is fixed to the first end in a fluid-tight manner, this baffle tube having a diameter greater than the third diameter of the heating element and less than the diameter of the airflow member. The baffle tube surrounds the forward portion of the heating element.
