Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. The following examples are presented to enable those skilled in the art to more fully understand the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1 and fig. 2, the following technical solutions are adopted in the present embodiment: the device comprises a fan system 1, a static pressure cavity 2, an air quantity splitter plate 3 and an air outlet 4; the fan system 1, the static pressure cavity 2, the air flow rate plate 3 and the air outlet 4 are all arranged on the side edge of an evaporator on the top of the display cabinet body, the evaporator of the display cabinet body is arranged on the top, an insulating layer is arranged on the outer side of the body of the display cabinet body, a glass cabinet door is arranged at the opening of the front side of the display cabinet body, a food placing area of the display cabinet body is provided with a plurality of layers of supports, and grid plates are arranged on the supports;
the fan system 1 is provided with a plurality of fans 11 which are arranged in parallel, and the fan system 1 is integrally and obliquely arranged at the top in the showcase body; the bottom of the fan system 1 is inclined to form a static pressure cavity 2 which is arranged upwards in an inclined mode, cold air blown out by the fan system 1 enters the static pressure cavity 2, an outlet of the static pressure cavity 2 is communicated with an air outlet 4, and the cold air coming out of the static pressure cavity 2 flows to the air outlet 4; the air outlet 4 is arranged at the outer side of the top of the display cabinet body, the air outlet 4 is obliquely arranged at the outer side, and the air outlet 4 is provided with a plurality of air outlet holes 43 which are uniformly distributed in parallel; the air flow distribution plate 3 is longitudinally arranged at the top of the air outlet 4, the air outlet 4 is divided into an inner air outlet branch port I41 and an outer air outlet branch port II 42 by the air flow distribution plate 3, the air flow distribution plate 3 is provided with a plurality of vent holes 31 which are uniformly distributed in parallel, most of cold air flowing out of the static pressure cavity 2 flows out through an air outlet 43 on the air outlet branch port I41 and enters an area for placing food, and a small part of cold air flowing out of the static pressure cavity 2 enters the air outlet branch port II 42 through the vent holes on the air flow distribution plate 3 and flows out of the air outlet 43 at the air outlet branch port II 42.
The cross-sectional area of the first air outlet branch port 41 is larger than that of the second air outlet branch port 42, so that most of cold air coming out of the static pressure cavity 2 flows out of the first air outlet branch port 41, a small part of cold air flows out of the second air outlet branch port 42, the cold air coming out of the second air outlet branch port 42 still passes through the air vent 31 of the air flow splitter plate 3, and the air flow is smaller.
