[0002] With the development of refrigeration and freezing technology, various types of refrigeration cabinets and freezers have been widely used in commercial places, such as convenience stores, supermarkets, etc. These devices are used to store beverages, food or other items that need to be stored at low temperature to extend the shelf life and keep fresh. However, traditional refrigeration cabinets or freezers often use simple one-way refrigeration method, relying on natural convection to achieve the distribution of cold air, which can easily lead to uneven temperature distribution, especially when storing a large number of items, the temperature difference between different areas in the cabinet is large, which is not conducive to the preservation of goods. At the same time, the traditional equipment often lacks effective air circulation design, and the cold air is easy to stay in some areas due to poor convection, which affects the refrigeration efficiency and increases the energy consumption. In addition, although the top opening design of some refrigeration cabinets is convenient for taking and placing goods, it can easily lead to the escape of cold air, reducing the overall refrigeration effect. Therefore, how to improve the structural design of refrigeration cabinet or freezer to improve the refrigeration effect, reduce energy consumption and achieve good air circulation is one of the current technical problems to be solved.
