In the utility model, the exhaust fan is started by an external control device, and the exhaust fan extracts the heat inside the shell, and at the same time reduces the air pressure inside the shell, and the external air pressure squeezes the air into the air pipe, and the air contacts the busbar through the air hole, and the air squeezes the hot air upward.
