| 20100200569 | CONTROLLED FORCE PTC HEATER - A self-regulating heater assembly comprises a positive temperature coefficient (PTC) heating element and a pair of spaced electrodes. Each electrode includes a first surface. The first surfaces of the pair of electrodes are spaced from one another. The PTC element is located between and supported by the first surfaces of the pair of electrodes and is energized by the pair of electrodes. Means for limiting a compressive force on the PTC element is provided. The means includes an electrically insulative spacer member positioned between the first surfaces of the pair of electrodes. A first pair of power leads, one power lead being connected to each of the pair of electrodes, energizes the pair of electrodes. | 08-12-2010 |
| 20110220638 | FINNED CERAMIC HEATER - A finned ceramic heater includes a ceramic heating assembly, a pair of electrode plates, a plurality of insulating pieces, an insulating adhesive, and a pair of fins. The pair of electrode plates is adhered to both side surfaces of the ceramic heating assembly respectively. The insulating pieces are connected in series and adhered to an outer surface of each electrode plate respectively. A seam is formed between two adjacent insulating pieces. The width of the insulating piece is larger than that of the electrode plate. The insulating adhesive is filled in the seam. Each of the fins is disposed on the insulating pieces and the insulating adhesive. With this arrangement, a larger tolerance in the thickness of each insulating piece can be obtained, thereby preventing the insulating pieces from cracking due to their inconsistent flatness and enhancing the insulating property of the heater. | 09-15-2011 |
