The invention relates to the field of cameras, the gun type camera with the heat dissipation function comprises a mounting frame, a fixing column is mounted on the right side of the top of the mounting frame, a rotating groove is formed in the top of the fixing column, a ball is rotatably connected in the rotating groove, a shell is mounted at the top of the ball, and a camera body is mounted in the shell. According to the gun type camera with the heat dissipation function, after the heat dissipation motor is started, the heat dissipation fan blades can be driven to rotate; when the heat dissipation fan blades rotate, air can be pumped into a hose from an air inlet; air is accelerated to pass through the hose and a heat dissipation opening to enter the shell; after entering the shell, high-speed gas is blocked by a partition plate, transmitted to the right side from the left side of the bottom of the camera, rotated upwards, moved from the right to the left and discharged from a gas outlet, so that the passing distance of the gas is longer, the contact time with the camera is longer, heat on the camera can be better taken away, and the heat dissipation effect on the camera is better.
