Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary testing, in particular to a testing auxiliary device for liquid constant temperature testing equipment. Background Art

[0002] The liquid constant temperature test equipment consists of a tank, a heater / cooler and a temperature control system. It monitors and controls the temperature of the working medium through sensors to keep it at a constant temperature. It is suitable for a variety of media such as water and ethanol.

[0003] The technical indicators of temperature in liquid constant temperature test equipment include temperature deviation, temperature uniformity and temperature fluctuation. When conducting tests, the positions of the measurement points of the temperature sensors are adjusted according to the size of the liquid constant temperature test equipment. When the depth of the working space is less than 15cm, the temperature sensors are arranged on the central horizontal plane, including the center point and the four corners of the same horizontal plane, for a total of 5 test points. When the depth of the working space is greater than 15cm, the temperature sensors are arranged on the upper horizontal plane, the central horizontal plane and the lower horizontal plane, with one test point at the center of the central horizontal plane, one test point at each of the four corners corresponding to the upper horizontal plane, and one test point at each of the four corners of the lower horizontal plane corresponding to the upper horizontal plane, for a total of 9 points. The temperature technical indicators are calculated based on the measured temperature points.

[0004] During the testing process of the liquid constant temperature test equipment, the following problems exist without auxiliary devices. (1) When the selected temperature sensor is light in weight, it cannot be fixed to the appropriate test point in the liquid of the liquid constant temperature test equipment, resulting in reduced measurement accuracy. (2) The flow of liquid during the operation of the liquid constant temperature test equipment will change the position of the temperature sensor. When there is no auxiliary device to fix the temperature sensor, the offset of the measurement point makes the data unreliable. (3) The flow of liquid during the test will cause the temperature sensor to drift, which may cause the temperature sensor to become tangled or move to the control area of the liquid constant temperature test equipment, causing damage to the equipment.
