The invention discloses a data center immersed-type liquid-cooling cabinet based on the heat pipe technology. A plurality of added cooler cabinets are vertically arranged outside a first side wall ofthe liquid-cooling cabinet. A plurality of server groups are disposed in a length direction parallel to the first side wall at a staggered manner, and are closely attached to the first side wall and asecond side wall facing the first side wall at intervals so as to form a first flow channel. A first refrigerant circulation pipe is communicated with the first flow channel. The interior of each added cooler cabinet is vertically provided with a plurality of heat pipe groups, and each heat pipe group comprises a plurality of horizontal heat pipes. A part of heat pipes stretch into the liquid-cooling cabinet, and are fixedly connected to the added cooler cabinets in a sealed manner. The interior of each added cooler cabinet forms a second flow channel through the gaps between the heat pipes,and a second refrigerant circulation pipe is communicated with the second flow channel and is connected with a refrigerating machine. The liquid-cooling cabinet can quickly dissipate the heat of a server, reduces local hotspots of the cabinet, improves the overall heat dissipation efficiency of a machine room, and reduces the energy consumption of a data center heat dissipation system.
