Module Calculations
width=16 DT:    - Temperature difference, Thot - Tcold.
width=16
 DT/DTmax:    - Ratio of the module's operating temperature difference to the DTmax of the module.
width=16
 l/lmax for lowest power:    - Ratio of the module's suggested operating current to the Imax of the module.
width=16
 Q/Qmax for lowest power:    - Ratio of Q to Qmax of a module that's been optimized for minimum power consumption.
width=16
 Qmax for lowest power:  - Qmax of a module that's been optimized for minimum power consumption.
width=16
 Q/Qmax for smallest size:    - Ratio of Q to the minimum Qmax capable of meeting the cooling requirements.
width=16
 Qmax for smallest size:  - Minimum Qmax of a module that will meet the cooling requirement. This generally translates to a module that is as physically small as possible.
