Heat dissipation structure of direct-current brushless hammer-breaking motor

The utility model discloses a heat radiation structure of a direct current brushless hammer-breaking motor. The structure comprises a direct-current brushless hammer-breaking motor, a heat dissipation module is arranged outside the direct-current brushless hammer-breaking motor, the heat dissipation module is composed of a shell and an end fan fixing shell installed at one side end of the shell, and a secondary fan fixing shell is arranged on the side wall of the shell; a groove is formed in the outer side face of the direct-current brushless hammering motor, a dustproof net plate is clamped to the outer side of the end fan fixing shell, a connecting rod is connected into the end fan fixing shell, and fan blades are installed on the connecting rod. The structure dispels wind, can quickly suck cold air into the motor, and is dust-proof and dust-suppression, and the bell mouth connector can enable the wind to enter the narrow mouth from the wide mouth, thereby accelerating the flow speed and reducing the temper
