The induction heater and a method for controlling overheating of an induction heater, and to an induction heater in which overheating of a heating element may be prevented by allowing a coolant to be introduced from a lower side, flow upwardly while being in contact with the heating element, and be then discharged to an upper side to improve air bubble discharge performance of the coolant, in the induction heater heating a heating element in an induction heating manner. In addition, the present invention relates to an induction heater and a method for controlling overheating of an induction heater in which a fault of the induction heater or a fire due to overheating may be prevented by deciding whether or not a heating element is overheated using one or more of a current sensing means and a temperature sensing means capable of sensing overheating of the heating element and performing a control to supply power to an induction coil or block power supplied to the induction coil depending on a decision result.

The present invention relates to a vehicle radiation heater being configured to perform heating by directly emitting radiant heat toward a passenger at an early stage of starting of a vehicle in winter. The vehicle radiation heater according to the present invention can be simple in structure, thereby being easy to manufacture, can quickly emit high-temperature radiant heat over the entire area of the heater, thereby enhancing rapid and comforting heating effects, and can maintain a constant temperature, thereby preventing a risk of overheating.

Vehicle radiation heater

The present disclosure relates to an air conditioning device for a vehicle seat; can include a seat duct formed on a seat of a vehicle, a seat air conditioning unit formed on a lower frame on which the seat is mounted, and a separation space interposed between the seat and the lower frame; and can be formed so that the air is discharged from the air conditioning unit into the separation space, and the air of the separation space is supplied to the seat duct. As a result, it is possible to enhance the mobility of the seat, and to prevent noise and vibration due to driving parts from being delivered to a passenger.

Air conditioning device for vehicle seat

The present invention relates to a radiant heater for a vehicle, the radiant heater including: a base fabric; a heating member stacked on the base fabric; a fixing member fixing the heating member to the base fabric; and a laminated fabric stacked on an upper side of the fixing member and combined with the base fabric. Thus, the heater can be formed in a woven form and thus manufactured quickly and simply, and a heating temperature of the heater can be easily controlled according to a location by only controlling a resistance pattern, thereby provide a more uniform warmth to a passenger of the vehicle.

Radiant heater for vehicle

According to one aspect of the present invention, carbon nanotubes whose diameter, length, crystallinity, purity and the like are adjusted to predetermined ranges are added to a thermoplastic resin, and thus the thermoplastic resin can be provided with improved electrical conductivity.
