[0025] Example 2

[0026] Based on the basis of example 1, the scheme in example 1 is further refined in combination with the specific working mode as follows: Figures 1 to 4 As shown in the following description:

[0027] In a preferred embodiment, the humidification mechanism 2 includes a water tank 10, a water inlet 11, and an atomizing nozzle 12. The water inlet 11 is located on one side of the water tank 10, and the atomizing nozzle 12 is located at the bottom of the water tank 10.

[0028] In a preferred embodiment, a door 13 is provided on one side of the working chamber 3, and a hinge 14 is provided on one side of the door 13.

[0029] In a preferred embodiment, the clamping mechanism 4 includes a fixed plate 16 and ball bearings 17. Two sets of fixed plates 16 are provided, and the two sets of fixed plates 16 are symmetrically arranged along the horizontal direction of the working cavity 3. A ball bearing 17 is provided on one side of the fixed plate 16. Several sets of ball bearings 17 are provided, and each set of ball bearings 17 is evenly distributed along the horizontal direction of the fixed plate 16. Furthermore, the fixed plate 16 is made of metal or hard plastic to ensure sufficient strength and stability, and can maintain the stable position of the cold storage panel during the test, avoiding the impact of vibration or external force on the test accuracy.

[0032] The working process of the utility model is as follows: first, the operator ensures that the water tank 10 is filled with water, and checks whether the atomizing nozzle 12 is unobstructed, then the operator places the cold storage plate between the two sets of fixed plates 16, once the cold storage plate is in place, the door 13 is closed to ensure that the working cavity 3 is sealed, and then the console 8 is used to set the test parameters, the cold air fan 5 and the warm air fan 7 start working according to the set parameters, respectively responsible for reducing and raising the temperature on both sides of the cold storage plate in the working cavity 3, and the humidifying mechanism 2 starts to work, the atomizing nozzle 12 sprays water mist to increase the humidity in the working cavity 3, and the console 8 adjusts the working state of the cold air fan 5, the warm air fan 7 and the humidifying mechanism 2 according to the monitoring data to ensure that the test environment meets the preset conditions. During the test process, various indicators of the thermal insulation performance can be observed in real time, and processed and recorded through a data analysis system. The above is the working principle of the thermal insulation performance test equipment for cold storage plate.
