The invention relates to a frame (3) for an electric heating device (1), comprising at least one housing (7) intended to receive a heating element (5), said housing being defined by a plurality of longitudinal walls (23, 25) forming an insertion path for a heating element, and said insertion path being defined longitudinally by a back wall extending opposite an opening through which the heating element can be inserted into the housing. According to the invention, at least one of the longitudinal walls comprises a displacement reducing element (10) projecting from the wall. The displacement reducing element (10) comprises a ramp (11) that slopes gradually into the housing, towards the opposite longitudinal wall, said displacement reducing element (10) being arranged such that the downstream end (14, 15) thereof extends at a distance from the back wall (21).

A multi-zone climate control system for vehicles includes a front HVAC unit and one or more additional units that can be configured to provide conditioned air to one or more rear climate zones. The front HVAC unit is adapted to condition air provided to at least one front climate zone. The front HVAC unit may include a cold air outlet that supplies cold air to an electrically-powered heater positioned in a console of the vehicle. The electrically-powered heater includes an electricity-to-air heat exchanger to control a temperature of conditioned air supplied to at least one rear zone of the passenger compartment. The system may include an auxiliary climate control system having an auxiliary heater core and an auxiliary evaporator positioned in a rear portion of the vehicle to provide conditioned air to one or more rear climate zones.

A heat generator includes an electrode terminal, a heating element, an electrically conductive housing, and an insulator. The electrode terminal is stacked on the heating element in a stacking direction. The housing houses a stacked body formed of the heating element and the electrode terminal. The stacked body includes a pair of side wall surfaces each extending in the stacking direction, an element side end surface, and a terminal side end surface. The element side end surface is in close contact with the case inner wall surface. Both the terminal side end surface and the pair of side wall surfaces are entirely in close contact with the case inner wall through the insulator. The housing includes a pair of facing walls facing and extending along the pair of side wall surfaces to serve as a positioning member that restricts the heating element from moving in the intersecting direction.

The present invention relates to a high-voltage heater that generates heat by using a heating effect of an electric current, and more particularly, to a high-voltage heater including a disconnection detection unit, which is capable of detecting disconnection of a heating unit by checking a voltage between the heating unit and a switching unit when a high voltage is applied even in a state in which a heater does not operate, and a disconnection detection method using the same.

The heater device has a sheet shaped main body having a heat generating portion heated by energization and a radiating surface for radiating radiant heat toward a heating object by using heat in the heat generating portion, a plate shaped member arranged on an opposite side with respect to the radiating surface of the main body, and an air layer forming member for forming an air layer between the main body and the plate shaped member arranged on a side opposite to the radiating surface of the main body.

The present disclosure describes a heating element for, e.g., an electrically drivable motor vehicle. The heating element includes a heating body having large heating areas oriented opposite one another, at least one insulating body for electrical insulation, and at least one functional body for providing an electrical conducting function and a bonding function. The at least one functional body includes a pair of fiction bodies having large functional body areas oriented opposite to one another. The pair of functional bodies are arranged on the heating body such that at least one large heating area lies substantially with its full surface area against a respective large functional body area of the respective functional body. The at least one functional body is of a two-part or multi-part structure.

A heater element for vehicle compartment heating in a vehicle, including a pillar-shaped honeycomb structure portion having: an outer peripheral side wall; and partition walls disposed inside the outer peripheral side wall, the partition walls defining a plurality of cells which form flow paths from a first end face to a second end face;
wherein the partition walls have PTC characteristics; an average thickness of the partition walls is 0.13 mm or less; and an open frontal area on the first and second end faces is 0.81 or more.

A heating, ventilation, and air conditioning (HVAC) system for a vehicle may include: a casing having an inlet and a plurality of outlets; an evaporator disposed within the casing; a heater core disposed behind the evaporator within the casing; and an air mixing door disposed between the evaporator and the heater core. In particular, the heater core and a rear wall of the casing are spaced apart from each other by a first distance, the evaporator and the heater core are spaced apart from each other by a second distance, and the first distance is greater than the second distance.

The present disclosure describes a PTC heating device for, e.g., an air-conditioning system of a motor vehicle. The PTC heating device includes first and second PTC thermistors each having a first and second electrical contacting surface that lie opposite one another. The PTC thermistors are arranged sandwiched between a first and a second electrical insulation. A first electrical line path is arranged between the first PTC thermistors and the first electrical insulation. The first electrical line path is electrically connected to the first contacting surface of the first PTC thermistors. A second electrical line path is arranged between the second PTC thermistors and the first electrical insulation. The second electrical line path is electrically isolated from the first line path and electrically connected to the first contacting surface of the second electric PTC thermistors.

The present disclosure generally relates to providing climate control within a vehicle. More particularly, the present disclosure relates to using an infrared (IR) heating module having one or more IR panels installed within a roof of a passenger cabin, the IR panel(s) configured to radiate heat to passengers within the vehicle at a low power. Vehicles having the IR heating module installed with various IR panel configurations within the roof are also provided. In addition, programs and instructions embodied within a computer or software program stored on a non-transitory machine-readable medium and executed by the controller of the IR heating module are provided.
