Spiral Microheaters

The objective of the use for free radiating devices is to maximize the radiative POWER transfer from the heating elements. If the heating element is covered with insulation, the objective of the user changes to obtain a certain temperature inside the insulated region. The control for temperature inside a chamber or power maximization in a free radiating mode can be made with MHI temperature and/or power controllers. For either objective, one cannot exceed the rated temperature of the heating element.

Description: MC-GAXP-485 (3)(Ceramic base provided with microheater does not have a lip. Picture for illustrative purposes only.)

Note that the maximum temperature is at the center of the spiral region unless asymmetric power delivery is required

In the diagram abve D1 and D2 are seperated by 0.1" T is 0.25" and H is 2.5"

For obtaining maximum temperature MHI controls are highly recommended. Large diameter GAXP® microheaters could develop some springiness from induced magnetic forces. Potting in ceramic paste is allowed as long as care is taken to factor-in the loss of any thermocouple response in the measured temperature. Note element temperature will be higher and maximum element temperature should not be exceeded. In the free radiation mode the power can be maximized.

The objective of the use for free radiating devices is to maximize the radiative POWER transfer from the heating elements. If the heating element is covered with insulation, the objective of the user changes to obtain a certain temperature inside the insulated region. The control of temperature inside a chamber, or power maximization in a free radiating mode can be made with MHI temperature and/or power controllers.

For either objective, one cannot exceed the rated temperature of the heating element. Power output will be lower in enclosed radiation mode with a temperature control feature as opposed to or in addition to the power control.
