Liquid-cooled server

A liquid-cooled server provided by the present invention comprises a chassis and a liquid-cooled heat dissipation system, the chassis is provided with an accommodating cavity, the accommodating cavity is internally provided with a main control board, a central processing unit, a memory bank and a graphic processing unit, and the central processing unit, the memory bank and the graphic processing unit are electrically connected with the main control board; at least part of the liquid cooling heat dissipation system is located in the containing cavity, the liquid cooling heat dissipation system comprises a liquid cooling link, and cooling liquid in the liquid cooling link flows through a liquid cooling plate at the position of the central processing unit, a liquid cooling assembly at the position of the memory bank and the graphic processing unit so as to take away heat generated by the central processing unit through the liquid cooling plate. Heat generated by the memory bank is taken away through the liquid c
