The invention discloses a multilayer even-temperature heating device for measuring the self surface temperature. The device sequentially comprises a temperature measurement resistor, a dielectric layer, a heating resistor and a thermal insulating layer from top to bottom. Wires of the heating resistor are arranged in an S shape, the two ends of the heating resistor and the two ends of the temperature measurement resistor are each externally connected with a constant current source to enable the heating resistor to radiate heat, wherein the temperature measurement resistor is coated with solder resist agents. The multilayer even-temperature heating device for measuring the self surface temperature can provide even temperature and also can measure temperature distributed on a plate conveniently; the thermal insulating layer allows the temperature to be transferred in the same direction; energy is saved, and the structure is simple.
Description
technical field [0001] The invention relates to a temperature-equalizing multi-layer heating device, in particular to a temperature-equalizing multi-layer heating device capable of identifying the temperature after external interference and measuring its own surface temperature. Background technique [0002] At present, the existing electric heating plate uses silicon rubber or glass fiber as an insulator on the outside of the heating layer, and is directly connected to a power supply for heating. When the surface is disturbed by the outside world, the temperature will change unevenly, and the temperature distribution cannot be measured. Generally, the uniform temperature heating plate cannot measure the surface temperature, which makes it difficult for experiments that need to detect changes in surface temperature distribution at all times. Contents of the invention [0003] In order to overcome the deficiency that the existing temperature chamber cannot measure the temp...
