Description

Technical Field

It utilizes the good heat conduction performance and high-temperature resistance characteristics of graphite materials to generate heat through power supply, providing a uniform and stable heating environment for various samples, reagents, etc. in experiments.

[0003] The Chinese patent discloses a graphite electric heating plate with uniform heating (publication number CN218550218U). This patented technology can compare with the first temperature sensor by adding a second temperature sensor, monitor the temperature difference between the temperature around the placement plate and the temperature in the middle of the placement plate, and regulate the electric heating devices around the placement plate to make the temperature around the placement plate consistent with the temperature in the middle of the placement plate. An insulation device is also added outside the electric heating device to reduce the heat dissipation of the electric heating device.

[0004] However, most of the existing heating methods for the placement plate only use the electric heating plate for heating. When heating, it cannot evenly transfer the heat to the placement plate, resulting in poor heating effect and low practicability. For example, in the above-mentioned comparative document, it adopts the heating method of the electric heating plate. In actual application, when heating through the electric heating plate, it cannot evenly transfer its heat to the placement plate, and the practicability is low. Therefore, those skilled in the art provide a graphite electric heating plate with uniform heating to solve the problems raised in the above background technique. Content of the Utility Model
