SPECIAL PATTERN OF PATHS DIAGRAM OF THE HEATER THAT COVERS A THIN HEATING PLATE FOR HIGH TEMPERATURE UNIFORMITY Russian patent published in 2018 - IPC H05B3/26 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and characterizes the pattern drawing of the heater circuit, designed to cover heating plate (100) to achieve a highly uniform heat distribution and rapid heating, low power consumption and prevent current compression by means of a high duty ratio, heating plate (100) comprising: substrate layer (101) which is electrically insulating, highly heat conducting, substrate with a low heat capacity, which is covered by the pattern drawing of the heater circuit, having conductive layer (102) and resistive layer (103), conductive layer (102) having conductive parts, such as power contact pads (201), main power lines (202) contact playgrounds (203) split conductor lines (204), formed by a highly conductive material for uniform distribution of power across resistive layer (103), resistive layer (103), having resistive portions containing resistive parts, formed by a resistive paste, for heating heating plate (100).

EFFECT: highly homogeneous heat distribution.
