HEATER BOARD (VARIANTS) Russian patent published in 2023 - IPC H05B1/00 H05B3/10 H05B3/12 H05B3/16 H05B3/20 H05B3/26 

FIELD: temperature control devices.

SUBSTANCE: invention relates to temperature control devices for heating or cooling. The technical result is achieved in that the heater board contains an electrically insulating base with a heater and a temperature sensor, each of which is made in the form of a conductor track. The length and width of the track of the temperature sensor conductor at a certain thickness are sufficient to fix a given change in resistance at the ends of this track, and the ends of each of the tracks are located on the surface of the board. A foil material with at least one copper conductive layer is used as an electrically insulating base. The tracks of the printed conductors of the heater and the temperature sensor are printed and located either on the same copper conductive layer, when the main part of the track of the printed conductor of the temperature sensor is made practically along the track of the printed conductor of the heater, or on different conductive layers opposite each other. The ends of the tracks can be located in the same area of the board, and the main parts of the tracks can be made in the form of "meanders" or "spirals".

EFFECT: ensuring maximum thermal connection between the heater and the temperature sensor, increasing the manufacturability, significantly reducing the cost of the product, simplifying the design.
