ABSTRACT:
An electric heater adapted to be extended through an aperture in a tank wall for immersion in a fluid to be heated includes an elongated heater block structure formed by a metal core cast in a tubular metal shell. The core has a plurality of axially extending cavities, each removably receiving an individual elongated electric heating element having a terminal end extending from an open end of the cavity. An end plate secured to the shell of the heater provides a radially projecting flange for use in connecting the heater to the tank. The terminal end of each heating element projects through the end plate and the wall of a terminal box. Packing devices are provided around the heating elements to seal apertures in the end plate and terminal box wall through which the heating elements extend. The terminal box is spaced from the end plate to isolate the box from the heater block and the tank in order to minimize the possibility of leakage of liquid into the box. The heater further includes a temperature responsive device positioned in an elongated cavity in the core and extending through the end plate to a control unit regulating the current supply to the heating elements. A plurality of axially extending perforated fins may be provided on the external surface of the shell for enhancing heat transfer to the fluid to be heated. A tubular sleeve connected at one end to the end plate may be provided in spaced relation to the shell to define a tubular chamber surrounding the heater for axial flow of the fluid to be heated.
