Abstract
A circuit board baking box with a heat energy recovery device comprises a baking box body, an exhaust pipe, an air supplement pipe and an exhaust gas main pipe. One end of the exhaust pipe and one end of the air supplement pipe are separately communicated with the baking box body. The other end of the exhaust pipe is communicated to an end portion of the exhaust gas main pip. The other end of the exhaust gas main pipe is communicated with the atmosphere. The other end of the air supplement pipe is communicated with the central portion of the exhaust gas main pipe. The exhaust gas main pipe between the exhaust pipe and the air supplement pipe is provided with a drawing fan. A heat energy recovery device is arranged between the exhaust pipe, the air supplement pipe and the baking box body. The heat energy recovery device comprises a heat absorption cavity and a heat release cavity. The exhaust pipe is communicated with the heat absorption cavity. The air supplement pipe is communicated with the heat release cavity. Heat between the heat absorption cavity and the heat release cavity is conducted through a heat conduction device. The beneficial effects are that: the circuit board baking box with the heat energy recovery device absorbs heat energy through the heat absorption cavity and the absorbed heat is transmitted to the heat release cavity through the heat conduction device so as to enable the heat energy to be released. Heating is carried out on normal temperature gasses which are supplemented into the baking box, so that temperature of the gasses which are supplemented into the baking box is raised; constant temperature power consumption is reduced; and the heating time is also reduced.
