High-density fin water-cooling radiator

The invention relates to a high-density fin water-cooling radiator which comprises a radiating bottom plate and at least one cover plate. A plurality of grooves are formed in the heat dissipation bottom plate, a plurality of fin plates are fixedly inserted in each groove, a plurality of heat dissipation flow channels are formed between the fin plates or between the fin plates and the side walls of the grooves, the heat dissipation flow channels of the adjacent grooves are communicated, and the fin plates are arranged in the grooves. The fin plate is provided with a plurality of protruding blocks which are arranged in a staggered mode and protrude towards the two sides. And the cover plate is fixedly connected with the heat dissipation bottom plate, a closed cavity is formed between the cover plate and the groove, and the heat dissipation flow channel is located in the cavity. The high-density fins are used for increasing the radiating area of the radiator and improving the radiating efficiency. The protruding
