By adopting the immersion type server cooling cabinet, the cross section of the server accommodating cavity 2 is set to be of the right trapezoid structure with the inclined waist face opened upwards, the server 3 is obliquely arranged in the cabinet body 1, part of the server 3 is located in the immersion area 21 and part of the server is located in the drying area 22, the immersion area 21 can be divided into two independent parts through the structure and the position of the server accommodating cavity 2, the refrigerant in one part of the area can flow randomly, the refrigerant in the other part of the area cannot flow randomly between the servers due to the blocking of the server 3, the refrigerant can only flow directionally, the heat dissipation effect of the servers with different performances in each area is prevented from being influenced by the liquid level channeling, the heat dissipation effect of the server cooling cabinet is further improved, the workload of server installation and maintenance is greatly reduced, other parts for blocking the refrigerant in the server to flow outside are not required, and the cabinet structure is simpler.
The cross-sectional shape of the server 3 in the drying area 22 may be changed according to the amount of the refrigerant supplied from the refrigerant pipe into the server accommodating chamber 2.
In particular, the cross section of the servers 3 located in said drying zone 22 may be triangular. By the triangular cross section of the server 3 in the drying area 22, the height of the server 3 exposing the refrigerant liquid surface 23 is relatively smaller under the condition that the refrigerant amount conveyed into the server accommodating cavity 2 is fixed, and the performance requirement of the server is met.
