초록 ▼

A heater system is provided that comprises a plurality of layered heater modules, each module comprising a plurality of resistive zones. The layered heater modules are disposed adjacent one another to form the heater system, which can be adapted for a multitude of different sizes of heating targets. Preferably, the resistive zones comprise a plurality of resistive traces arranged in a parallel circuit and oriented approximately perpendicular to a primary heating direction, wherein the resistive traces comprise a positive temperature coefficient material having a relatively high TCR. The resistive traces are responsive to the heating target power gradient such that the resistive traces output additional power proximate a higher heat sink and less power proximate a lower heat sink along the primary heating direction.

1. A heater system comprising: a plurality of layered heater modules, each module comprising a plurality of resistive zones,wherein the layered heater modules are disposed adjacent one another to form the heater system, and the resistive zones comprise a plurality of resistive traces arranged in a parallel circuit and oriented perpendicular to a primary heating direction, the resistive traces comprising a positive temperature coefficient material having a temperature coefficient of resistance (TCR),wherein when heat loss along the primary heating direction is different, the resistance of one or more of the resistive traces decreases due to a higher heat loss to an adjacent heat sink, causing the one or more of the resistive traces to have a lower temperature, and the one or more of the resistive traces generate more heat to compensate for the higher heat loss to the adjacent heat sink due to the decreased resistance and increased power of the one or more of the resistive traces. 2. The heater system according to claim 1, wherein the resistive traces of at least one resistive zone are arranged in a linear configuration and the resistive traces of at least another resistive zone are arranged in an arcuate configuration. 3. The heater system according to claim 1 further comprising at least one aperture formed in each of the layered heater modules for mounting the layered heater modules to a heating target. 4. The heater system according to claim 1 further comprising at least one provision for the mounting of a sensing device. 5. The heater system according to claim 1, wherein the resistive zones are adapted for independent control. 6. The heater system according to claim 1, wherein the layered heater modules further include a plurality of dielectric layers and protective layers, the dielectric layers providing electrical isolation, the protective layers being one selected from the group of an insulator, an electrically conductive material, and a thermally conductive material. 7. The heater system according to claim 6, wherein the layered heater modules further comprise electrical leads in contact with terminal pads disposed on the dielectric layers; the leads connecting the resistive traces to a power source. 8. The heater system according to claim 4, wherein the provision is one selected from the group of an opening and a groove. 9. The heater system according to claim 1, wherein the layered heater modules are arranged adjacent to one another such that the heater system formed substantially matches the size of a heating target. 10. The heater system according to claim 1, wherein the layered heater modules are disposed adjacent to one another such that their resulting geometry is one selected from the group of flat, cylindrical, and curved. 11. The heater system according to claim 1, wherein upon responding to the heating target power gradient, the voltage applied across the resistive traces remains constant. 12. A heater system comprising: a plurality of layered heater modules placed adjacent to one another along their edges to form the heater system; the heater system sized for a specific size of a heating target;wherein each layered heater module includes a plurality of resistive traces connected to power buses and a pair of terminals that are connected to the power buses, such that each resistive trace within each module represents an independently controlled resistive circuit,wherein the resistive traces are arranged in a parallel circuit configuration and are oriented perpendicular to a primary heating direction.
