Airflow dehumidification module for refrigerating and freezing devices and refrigerating and freezing devices

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 has a storage compartment for storing articles. One end of the airflow dehumidification module communicates with the storage compartment, and the other end communicates with the external environment. The airflow dehumidification module is provided with a fin assembly to allow the moisture in the airflow flowing through the airflow dehumidification module to condense on the fin assembly, so as to condense and dehumidify the airflow flowing from the external environment to the storage compartment, so that it flows to the storage room The airflow in the storage compartment is a dry airflow with very low humidity, which prevents a large amount of frosting caused by the high-humidity airflow in the storage compartment, reduces the amount of frosting, and improves the user experience. The fin assembly includes a plurality of fin channels separated by a plurality of condensing fins arranged at intervals, and the plurality of condensing fins are arranged so that the air flow through each fin channel is the same, so as to more fully The branch airflow is fully condensed and dehumidified.

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
