Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, and more specifically, to a novel temperature sensor for refrigeration equipment. Background Art

[0002] The temperature sensors used in existing refrigeration equipment on the market all have pure metal shells. Due to the good electrical conductivity of the metal material, the surface of the shell cannot be completely insulated, and it cannot be installed in a space with high current and voltage. Since the metal material has a fast heat conduction performance, when the temperature drops rapidly, water vapor adheres to the surface of the shell, and the saturation of the water vapor begins to increase, resulting in frosting on the surface of the shell during use, thereby affecting the performance of the thermistor and it cannot be widely used in equipment for rapid refrigeration and precise refrigeration. Therefore, a novel temperature sensor for refrigeration equipment is proposed to solve the above problems. Summary of the Utility Model
