Study of Heat Transfer Plates - Radiantec

The aluminum heat transfer plates have a unique and generally unappreciated property. Aluminum has what is called “low emissivity”. The emissivity of aluminum is .05 vs. .95 for ordinary materials. That means that when aluminum is warm, it emits radiant energy at a much lower rate than most other materials (only 5% as much).

Emissivity Table What is Emissivity? Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermally black surface (a black body). A black body is a material that is a perfect emitter of heat energy and has an emissivity value of 1.
