Tailored heat transfer layered heater system
Methods of assembling a high heat transfer and tailored heat transfer layered heater systems are provided. One method includes a step of pressing one of a target part and a layered heater into the other one of the target part and the layered heater to create an interference fit between the layered heater and the target part. When the target part is disposed within the layered heater, the layered heater includes a substrate defining an inner periphery less than or equal to an outer periphery of the target part. When the layered heater is disposed within the target part, the layered heater includes a substrate defining an outer periphery larger than or equal to an inner periphery of the target.
