As a non-limiting embodiment, the heater preferably includes most or all of the following components: an outer casing or housing, at least one air intake vent, a magnetron, a microwave emitter, a wave scatterer, at least one fluid holder, fluid, a capacitor, a transformer, a microwave containment casing, and a perforated microwave guard. As another non-limiting embodiment, the heater preferably includes most or all of following components: an outer casing or housing, a cooling fan, a magnetron, a microwave emitter, a wave scatterer, at least one non-freeze liquid holder, non-freeze liquid, a capacitor, a transformer, a microwave containment casing, a glass tube, a metal tube, a fan coil, a pump, a reservoir and expansion tank, and a fill plug.

A heater device includes a heat generating portion formed so as to be adjacent to one surface of an insulating substrate and configured to generate heat, and a heat equalizing portion arranged between adjacent heat generating portions and configured to diffuse the heat of the heat generating portion. The heat generating portion has a linear shape, and at least one of a distance between one of the adjacent heat generating portions and the heat equalizing portion and a distance between the other of the adjacent heat generating portions and the heat equalizing portion is equal to or less than a line width of the heat generating portion. In the heat equalizing portion, a distance between one end of one of the adjacent heat generating portions and the other end of the other of the adjacent heat generating portions is longer than the line width of the heat generating portion.

A heating system for a vehicle is provided. In order to permit provision of efficient heating of a vehicle window pane of an electric vehicle, the system has two at least mainly transparent panes, wherein an outer pane is arranged on the outside of the vehicle and an inner pane is arranged on the inside of the outer pane to form an intermediate space, and at least one controllable infrared source is configured to irradiate infrared radiation into the intermediate space so that the infrared radiation at least partially irradiates the outer pane.

A vehicle includes a steering column, a radiant heater arranged in the steering column and configured to radiate radiant heat toward an area below the steering column, an instrument panel that defines part of an opening where the steering column passes and that extends in a lateral direction of the vehicle, an inside air sensor adjoining the opening in the instrument panel and configured to detect an indoor temperature of the vehicle, and a lower cover arranged below the steering column and defining the opening together with the instrument panel. At least the instrument panel or the lower cover includes a shielding wall positioned between the radiant heater and the inside air sensor.

A heater control device controls an electric heater which includes a plurality of heat generating portions. The heater control device determines whether a total energization current value, which is a current value to be supplied to the electric heater when all of the plurality of heat generating portions are energizable, exceeds a predetermined current limit value. The heater control device is configured to, when it is determined that the total energization current value exceeds the current limit value, energize the electric heater while switching, among any or all of the plurality of heat generating portions, those to be turned to a non-energizable off state.

Systems and methods for operating a hybrid vehicle are presented. In one example, electric current may be supplied to or withheld from a positive temperature coefficient (PTC) heater and an electrically heated catalyst. In particular, electric current may be delivered to the PTC heater and withheld from the electrically heated catalyst, or vice-versa, in response to a catalyst temperature and battery state of charge.

A heating apparatus has a heater body and a heater case. The heater body has a heat generator and emits heat supplied from the heat generator: The heat generator generates the heat when being energized. The heater case houses the heater body and is arranged on a side of an air-bag device for a vehicle adjacent to a vehicle compartment. The heater case is attached to an interior member located in the vehicle compartment or is a part of the interior member. The heater case has an expansion permissive portion that permits the air-bag device to expand into the vehicle compartment. The heat generator includes a portion located at a position corresponding to the expansion permissive portion. The heater body has a low strength portion that has a low strength as compared to the portion of the heat generator and that is located outside the expansion permissive portion.

An embodiment provides a vehicle heating device for heating a vehicle interior through heat radiation or heat convection using a heating unit connected to an air-conditioning casing. Accordingly, the vehicle heating device may improve the performance, efficiency, and quality in heating the vehicle interior through at least any one of heat convection and heat radiation using the heating unit.
