Abstract
A heater is provided with a heater core having a source of thermal energy in a heat exchange relationship with a heat exchanger. A fan moves air through the heater core from an air inlet to an air outlet. The heater core is thermally insulated by an air jacket from an exterior case.
Claims20
A heater, comprising:
- an exterior case comprising an air inlet and an air outlet;
- a heater core within the exterior case and being in communication with the air inlet and the air outlet;
- a fan communicating with the air inlet and the air outlet for moving air through the heater core;
- said heater core comprising a source of thermal energy and a heat exchanger, the heat exchanger comprising an inner cylinder and an outer cylinder, the inner cylinder being disposed adjacent and surrounding the source of thermal energy and the outer cylinder surrounding the inner cylinder to define an intermediate chamber between the inner and outer cylinders;
- and
- said inner and outer cylinders of said heat exchanger each oriented along a longitudinal axis extending between walls of said exterior case wherein said air inlet and air outlet are disposed.

A heater, comprising:
- an exterior case comprising an air inlet and an air outlet;
- a heater core within the exterior case and being in communication with the air inlet and the air outlet;
- a fan communicating with the air inlet and the air outlet for moving air through the heater core;
- said heater core comprising a source of thermal energy and a heat exchanger, the heat exchanger being disposed within the heater core and extending along a longitudinal axis extending between walls of said exterior case wherein said air inlet and air outlet are disposed, the heat exchanger comprising an inner cylinder surrounding the source of thermal energy and an outer cylinder surrounding the inner cylinder;
- and
- an air pathway defining a path of air movement progressing from the air inlet, through the heat exchanger, and out the air outlet, wherein the air pathway progresses through the heater in a direction substantially parallel to the longitudinal axis.

A heater, comprising:
- an exterior case comprising an air inlet and an air outlet;
- a heater core within the exterior case and being in communication with the air inlet and the air outlet;
- a dividing wall separating the heater core into a first portion adjacent the air inlet and a second portion adjacent the air outlet, the dividing wall inhibiting fluid communication between the air inlet and air outlet, the dividing wall further comprising an opening extending therethrough;
- a fan communicating with the air inlet and the air outlet for moving air through the heater core;
- said heater core comprising a source of thermal energy and a heat exchanger, the heat exchanger being disposed within the heater core and comprising an inner cylinder surrounding the at least one source of thermal energy and an outer cylinder surrounding the inner cylinder,
- wherein the heat exchanger is in fluid communication with the opening, such that air moving through the heater core from the first portion to the second portion is forced to proceed through the heat exchanger prior to being discharged through said opening and thereafter through the air outlet.
