Description

Sealing door structure and constant temperature and humidity equipment Technical Field The invention relates to the technical field of constant temperature and humidity, and particularly provides a sealing door structure and constant temperature and humidity equipment. Background The constant temperature and humidity box is used as key ring test equipment, is widely applied to the fields of electronic components, biological products, material science, medicine research and development and the like, and has the core function of maintaining the accurate stability of the temperature and humidity in the box body within a set time range, thereby ensuring the reliability and reproducibility of test conditions. Therefore, uniformity and stability of environmental parameters in the box are key indicators for measuring the performance of the equipment. In the actual use process, the sealing performance of the box door directly influences the control precision of the internal environment. At present, a common constant temperature and humidity box is mostly sealed by adopting a rubber sealing strip matched with a mechanical pressing device. However, after long-term use, the structure is easy to deform due to aging of sealing materials, elastic attenuation or repeated opening and closing of the box body, so that partial gaps or uneven attaching pressure between the sealing strip and the door frame are caused. In addition, the heat pressure difference generated by the temperature difference between the inside and the outside of the box body can aggravate the convection exchange of air through the tiny gaps, and the fluctuation of the temperature and the humidity in the box body is caused. Especially when high-precision constant temperature experiments are carried out, even tiny heat leakage or moisture leakage is enough to cause frequent adjustment of a control system, so that not only are temperature uniformity and fluctuation indexes influenced, but also energy consumption is possibly increased, and the service life of core refrigerating and heating elements is possibly shortened. Accordingly, there is a need in the art for a new solution to the above-mentioned problems.
