Airflow dehumidification module for refrigerating and freezing device and refrigerating and freezing device

Abstract

The invention relates to an airflow dehumidification module for a refrigerating and freezing device and the refrigerating and freezing device. The refrigerating and freezing device is provided with astorage chamber. One end of the airflow dehumidification module communicates with the storage chamber, and the other end of the airflow dehumidification module communicates with the external environment. A fin assembly is arranged in the airflow dehumidification module, so that moisture in airflow flowing through the airflow dehumidification module is allowed to be condensed on the fin assembly, the airflow flowing to the storage chamber from the external environment is condensed and dehumidified, the airflow flowing to the storage chamber is dry airflow with very low humidity, a large amountof frost is prevented from being generated in the storage chamber, the frosting amount is reduced, and the user experience is improved. The fin assembly comprises a plurality of fin channels formed byseparating a plurality of condensation fins arranged at intervals, and a first flow guide mechanism used for guiding and distributing the airflow flowing to the fin assembly is arranged at an airflowinlet of the fin assembly, so that the airflow passing through all the fin channels is the same in flow, and the airflow can be condensed and dehumidified more sufficiently.

Description

technical field [0001] The invention relates to refrigerating and freezing technology, in particular to an airflow dehumidification module used for a refrigerating and freezing device and the refrigerating and freezing device. Background technique [0002] Refrigeration and freezing devices, such as refrigerators, freezers and freezers, are common electrical equipment used to store various items that need to be refrigerated or frozen, and are widely used in households, supermarkets and other industries. After being used for a period of time, the refrigerator and freezer will form frost on its inner wall (especially the freezer, the amount of frost produced by it is more obvious). An important reason for frosting is that when the compressor is turned on and off, the pressure inside the refrigerating and freezing device changes, and the humid air from the external environment enters the inside of the refrigerating and freezing device through the door gap, and then the moisture...

Problems solved by technology

However, the problem with this method is that the desiccant in the ventilation pipe has a short service life and needs to be replaced regularly, which is difficult to operate and increases the user's use cost; in addition, the hot air is directly introduced into the refrigerating and freezing device, which increases the cost of refrigerating and freezing. device energy consumption
