Specifically, the storage chamber of the horizontal air-cooled freezer in the present embodiment is divided into a freezing chamber 101 and a variable temperature chamber 102 that are independent of each other through a thermal insulation partition 10, so as to store items in multiple temperature zones. The freezing chamber 101 needs more cooling capacity, therefore, along the cold air flow direction of the side outlet duct 12, the evaporation chamber, the freezing chamber 101 and the temperature-changing chamber 102 are arranged in sequence , so that the cold air output from the evaporation chamber first enters the freezing chamber 101 to meet the cold capacity requirement of the freezing chamber 101 . Wherein, one end of the horizontal cabinet 1 is provided with an end air outlet 11 and the side air outlets 12 of the two side walls are located in the freezing cavity 101 to realize three-sided air supply, wherein the air outlet of the end air outlet 11 The direction is toward the other end of the horizontal cabinet body 1, so that the cold air output from the air outlet of the end air outlet duct 11 can cover the entire cross section of the freezing chamber 101, while the air outlet direction of the side air outlet duct 12 is consistent with the end The air outlet directions of the part air outlet ducts 11 are staggered, and the wind output from the side air outlet ducts 12 impacts the wind output from the end air outlet ducts 11, thereby forming a vortex airflow inside the freezing chamber 101, and the vortex The air flow can ensure that the longitudinal section of the horizontal cabinet body 1 maintains a uniform distribution of cooling capacity, so that the temperature in the freezing cavity 101 is kept uniform on the whole to improve the cooling effect; The air outlet channel 14 introduces the cold air transported in the corresponding side air outlet channel 12 into the variable temperature cavity 102, and in order to make the temperature distribution in the variable temperature cavity 102 uniform, the auxiliary air channel 14 is arranged in the horizontal cabinet On the corresponding side wall and the other end of the body 1 , the auxiliary air outlet 14 has an L-shaped structure as a whole, so that cold air can be delivered from two directions, and the uniformity of temperature distribution in the variable temperature cavity 102 can be improved.
