Liquid-cooling heat radiation structure

The utility model provides a liquid-cooling heat radiation structure comprising a single heat conduction module and a combined water supply module. The single heat conduction module comprises a heat conduction substrate in contact with a heating source, a plurality of heat conduction fins fixedly arranged on the heat conduction substrate, a heat conduction splitter plate fixedly arranged on the heat conduction substrate and covering the plurality of heat conduction fins, and a heat conduction flow deflector fixedly arranged on the heat conduction splitter plate. The combined water supply module comprises an outer cover detachably arranged on the heat conduction substrate, and a rotating member detachably arranged between the outer cover and the heat conduction flow deflector. The plurality of heat conduction fins, the heat conduction splitter plate and the heat conduction flow deflector are disposed inside the outer cover. According to the utility model, cooling liquid enters into the outer cover from an liquid inlet under the driving of the rotating member, and the cooling liquid is in direct contact with the single heat conduction module, so that the heat transmitted from the heating source to the single heat conduction module can be absorbed by the cooling liquid.
