At the same time, exhaust pipes are installed on both sides of the heat dissipation hood to connect to the exhaust fan, so as to speed up the external heat dissipation of the heating furnace and avoid affecting the external equipment components. At the same time, an adjustable exhaust valve is set to adjust the exhaust volume. BRIEF DESCRIPTION OF THE DRAWINGS
