Embodiment 1

[0051] like figure 2 As shown, the cooling system of the downflow server cabinet in this embodiment includes:

[0052] like figure 1 As shown, the cabinet 1 includes a front side panel 11, a rear side panel 12, a left side panel 13, a right side panel 14, a top side panel 15 and a bottom side panel 16 which are sealed and connected to each other, wherein the front side panel 11 and the bottom side panel The rear side panel 12 has an opening 17 for the insertion of servers and the intake and discharge of airflow;

[0053] The underground air duct 2 is arranged on the lower surface of the bottom side plate 16 for the underground transmission of the air flow, and the top of the underground air duct 2 has an air return port 22 and an air outlet 21;

[0054] The front door 3 is sealingly connected with the front side panel 11, and there is a hollow structure including a cavity between the front door 3 and the front side panel 11, and the cavity forms a front channel 31 for the f...

Embodiment 2

[0070] Such as image 3 As shown, the difference between this embodiment and the first embodiment is that the top side 32 of the front door 3 is set as an arc-shaped guide surface 32 , and the top side 42 of the rear door 4 is set as an arc-shaped guide surface 42 . combine image 3 and Figure 4 , the top side 32 of the front door 3 is set as an arc-shaped guide surface 32, and the top side 42 of the rear door 4 is set as an arc-shaped guide surface 42 so that the airflow in the refrigeration system can pass through the front door 3 and the back door The top of 4 has a smooth transition, so that the entire air circulation is smoother, so as to improve the air circulation efficiency of the refrigeration system and make the refrigeration efficiency more efficient.

[0071] To sum up, the server cabinet refrigeration system with downflow air of the present invention designs the entire refrigeration cycle as a closed type, so that the air flow inside the refrigeration system wi...
