Heat dissipation device with good heat dissipation effect

The utility model relates to the technical field of heat dissipation devices, in particular to a heat dissipation device with a good heat dissipation effect, which is characterized in that the upper end of a base is fixedly connected with a fixed rod, and the center position of the upper end of the base is fixedly connected with a base heat conduction paste; the center of the bottom face of the pressing plate is fixedly connected with a pressing plate heat conduction paste, and a through hole is formed in a plate body of the pressing plate and is in sliding connection with the fixing rod. The heat conduction copper pipe is fixedly connected to the end, away from the pressing plate heat conduction paste, of the pressing plate, and heat dissipation fins are fixedly connected to a pipe body of the heat conduction copper pipe. The heat dissipation device has the advantages that the pressing plate and the base are fixed through threaded connection of the four fixing rods and the locking nuts, heat dissipation is c
