Air duct system of horizontal type freezer and freezer

Abstract

The invention discloses an air duct system of a horizontal type freezer and the freezer. The air duct system comprises an evaporator, a fan assembly, inlet air ducts, a return air duct, wherein the evaporator is located in an evaporator cavity; the evaporator cavity is located at one end of a box body in the length direction; the fan assembly is located above the evaporator; one end of each inlet air duct and one end of the return air duct respectively communicate with the upper part and the lower part of the evaporator cavity; the fan assembly is a centrifugal fan assembly with a volute structure; the inlet air ducts comprise two groups of inlet air ducts respectively arranged on two sides of a compartment; each group of inlet air ducts consist of a main inlet air duct and an auxiliary inlet air duct which are arranged in the vertical direction side by side; the main inlet air ducts and the auxiliary inlet air ducts extend to the other end of the box body in the length direction; and a plurality of air inlets communicating with the compartment are formed in the main inlet air ducts and the auxiliary inlet air ducts. The air duct system has the advantages that cold air is supplied to one end, away from the evaporator, of the horizontal type freezer through the inlet air ducts, and the refrigeration efficiency of the freezer is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air duct system of a horizontal freezer and the freezer. Background technique [0002] Air-cooled refrigeration is to force the air convection through the fan, and bring the cold generated by the evaporator into the storage compartment for cooling. Because of its fast cooling speed and no frost, it is more and more popular among consumers. [0003] There are already many vertical frost-free freezers in the existing products. The cooling method is basically the same as that of the freezer of the air-cooled refrigerator, that is, the wind blows from the back of the compartment to the compartment. When there is a lot of food, it is difficult for the air volume to circulate in the entire compartment, and it is difficult for the cooling capacity to reach the end far away from the evaporator, which is easy to form a dead angle in the circulation, resulting in a larg...

[0003] There are already many vertical frost-free freezers in the existing products. The cooling method is basically the same as that of the freezer of the air-cooled refrigerator, that is, the wind blows from the back of the compartment to the compartment. When there is a lot of food, it is difficult for the air volume to circulate in the entire compartment, and it is difficult for the cooling capacity to reach the end far away from the evaporator, and it is easy to form a dead angle of circulation, resulting in a large temperature difference inside the freezer and poor storage effect
