Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold storage agent freezing cabinet, in particular to a drawer type cold storage agent freezing cabinet. BACKGROUND

[0002] The cold storage agent can absorb and store a large amount of cold at low temperature, and release a large amount of cold at higher temperature, so as to maintain the low temperature environment of itself and the surrounding small range for a relatively long time. The cold storage agent has the advantages of simple device and small size, and can be widely used for cold preservation and distribution of fruits, river and sea foods, foods and other goods that need to be frozen and transported. The premise of using the cold storage agent for cold preservation is to freeze the cold storage agent at low temperature, and the cold storage agent freezing cabinet is usually used for freezing the cold storage agent at low temperature.

[0003] At present, the existing cold storage agent freezing cabinet generally makes the cold air flow from the top of the cabinet to the bottom of the cabinet along the air duct, realizes the temperature reduction of the goods by energy exchange between the cold air and the air in the cabinet, and then absorbs the cold air into the return air inlet through the fan of the return air inlet at the top of the cabinet, so as to realize the circulation of the cold air. However, because the cold air flows from top to bottom, the cold quantity is consumed from top to bottom during the temperature reduction process, so that the temperature of the cold air at the top of the air duct is lower, and the temperature of the cold air near the bottom of the freezing cabinet is higher, thereby causing the temperature difference between each layer of drawers, the different preservation temperatures of the goods in the cabinet, and the influence on the use of the freezing cabinet.
