Description

Technical Field

[0001] The utility model relates to temperature-resistant experimental equipment for sensors, belonging to the technical field of sensors. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. After the temperature sensor is produced, it needs to undergo a temperature resistance test, that is, one end of the temperature sensor is inserted into a heating box, and a heating resistor and a cooling plate electrically connected to an external power supply are installed in the heating box. After the heating resistor is heated, the electrical energy is converted into thermal energy. When the cooling plate works, the temperature in the heating box is lowered, which is convenient for the temperature sensor to undergo a temperature resistance test. When the temperature resistance test of a temperature sensor is completed and the next temperature sensor is subjected to a temperature resistance test, the heat remaining in the heating box will be wasted when the temperature inside the heating box is lowered, and when the temperature inside the heating box rises again, the consumed electrical energy increases. Therefore, it is necessary to design a sensor temperature resistance test equipment that utilizes the heat in the heating box. Utility Model Content

[0011] Beneficial effects of the utility model:

[0012] 1. When it is necessary to lower the temperature in the heating box from high to low, one electric push rod is controlled to contract, and the contracted electric push rod drives the water storage box connected thereto to move upward. At this time, one water storage box is higher than the heating box, and the other water storage box is lower than the heating box, so that the water in the water storage box higher than the heating box flows into the heat exchange tube in the heating box, and the water flowing into the heat exchange tube exchanges heat with the hot air in the heating box, and the water absorbing heat flows into the water storage box lower than the heating box, so that the temperature in the heating box is reduced, which is beneficial to shortening the working time of the refrigeration plate. When it is necessary to raise the temperature in the heating box from low to high, the other electric push rod is controlled to contract, so that the water storage box lower than the heating box is higher than the heating box, and the other water storage box is lower than the heating box. At this time, the water absorbing heat in the water storage box flows into the heat exchange tube, thereby heating the inside of the heating box, which is beneficial to shortening the working time of the heating resistance wire, realizing the utilization of the heat in the heating box, and reducing the consumption of electric energy.
