Abstract
Description
Technical Field
[0001] The utility model relates to the field of heating equipment, in particular to a SiC electric heating plate. Background Art
[0002] The heating plate is a device that converts electrical energy into thermal energy to heat objects. It is widely used in production, scientific research, and testing. Existing heating plates generally have a heating wire on the base, and the upper surface of the heating wire is covered with a thermal conductive material. Currently, the more commonly used materials are thermal conductive materials such as graphite and stainless steel. Although the thermal conductivity is good, the graphite material is soft and slags off. If the heating surface is contaminated, it is not easy to clean. Stainless steel is not resistant to strong acid corrosion, which can easily cause equipment damage and aging. The SiC material has a high thermal conductivity and high hardness. It is also acid and alkali resistant and easy to clean. Therefore, the heating surface of the heating plate can heat up quickly and be heated more evenly. Therefore, it is necessary to improve the structure of conventional electric heating plates. Utility Model Content
