The invention relates to a heat dissipation device of a mobile cabinet level
server system. The heat dissipation device comprises a plurality of water-cooling hot
pipe heat dissipation modules, a pipeline
system, a rear door heat dissipation device and a
control system, wherein the plurality of water-cooling hot
pipe heat dissipation modules are arranged in a mobile cabinet, each
electronic equipment needed to be cooled in the mobile cabinet is corresponding to one of the water-cooling hot
pipe heat dissipation modules, accurate heat dissipation of a heating part can be achieved, and the heat dissipation efficiency is substantially improved; compared liquid cooling with traditional
air cooling, a medium of liquid cooling is relatively large in
specific heat capacity, more heat can be taken away, meanwhile, the heat dissipation device is relatively quite during running, and
noise can be reduced very well; a hot pipe is good hot conductor, is high in
safety coefficient and low in cost and is widely used in the field of heat dissipation, the problem of heat dissipation of a high-flux density component in the field of heat dissipation can be solved very well by combining
water cooling and the hot pipe, and the reliability of the component is improved; compared with
air cooling, the
noise of the hot pipe can be reduced; and a
liquid cooling system is low in power during normal working, and more energy is saved.
