The described technology provides an electric heating apparatus with multiple heating lamps that can increase the heat emitted by a single heating apparatus, thereby allowing a minimal number of heating apparatus installations in the space where heating is needed, and can prevent fires by turning the power off immediately in the event of the heating apparatus falling off. According to the described technology, multiple heating lamps may be positioned within the reflector dish, and the heating lamps may have particular inclinations to allow a broader range of irradiation and increase efficiency in terms of installing, maintaining, and operating the electric heating apparatus; the heat of the reflector dish and the heating lamps themselves may be discharged by way of conduction at the upper portion of the reflector dish.

A heating system may include at least two different types of heating elements. The heating elements may include at least one infrared heating element and at least one halogen lamp. The heating elements may be positioned within a heating section of a duct through which air flows to be heated by the heating elements, which air flow may be driven by a fan. The heating system may be incorporated into a variety of heating devices, such as electric fireplaces and space heaters.

An electric radiator is provided using calculating processors as a heat source and includes a heating body where the heat transfer between the heat source and the ambient air takes place; a number of processors distributed over a number of printed circuit boards forming the heat source of the radiator and a power resource carrying out calculations by external computer systems; a man-machine interface enabling the control of the calculating and calorific power supplied by the radiator; a power source stabilized for the different electrical components; and a network interface for connecting the radiator to the external networks.

A hot gas generation device with which a gas flow, for example, an air flow, is heated. This device is used for heating an edge band or another coating material, in particular an adhesive layer provided on this coating material. In this way, the coating material is prepared for being applied to a (wooden) work piece, which may, for example, be plate-shaped.

A column-conditioning enclosure includes a column chamber adapted to hold one or more chromatography separation columns. A duct system provides an airflow path around the column chamber such that the one or more chromatography separation columns held within the column chamber are isolated from the airflow path. An air mover disposed in the airflow path generates a flow of air within the duct system. A heat exchanger system disposed in the airflow path near the air to exchange heat with the air as the air flows past the heat exchanger system. The air circulates through the duct system around the column chamber, convectively exchanging heat with the column chamber to produce a thermally conditioned environment for the one or more chromatography separation columns held within the column chamber.

An electric heating device includes at least two hollow profile elements which form a fluid channel for a fluid to be heated and, opposite the fluid channel, a heating chamber which is bounded by opposite contact surfaces against which at least one PTC element abuts in a heat-conducting manner. A scalable and easier to assemble electric heating device is achieved by connecting the hollow profile elements to one another by complementary form-fit segments.

An air conditioner may include a casing having an inner air flow space defined therein and an entrance defined in one of a first side plate or a second side plate, a heat exchanger and a fan disposed between an outdoor air inlet body and an air outlet body in an air flow direction of the casing, a heater module inserted through the entrance into the inner air flow space, a handle mounted on one side face among both side faces of the heater module, one side face of the both side faces being closer to the entrance than the other side face thereof, a pair of guide brackets installed in the casing to slidably guide the heater module, and a door module that opens and closes the entrance. The door module may be configured to contact the handle to press the handle in a direction away from the entrance.

A heat exchanger includes a temperature sensor for a vehicle heating device, a heat input surface, an electrical heating element arranged on the heat input surface, and a heat output surface. The temperature sensor is arranged in a depression on the heat output surface.
