Abstract
A circuit board oven with a heat recovery device comprises an oven body, an exhaust pipe, an air supply pipe and a waste gas main pipe. One end of the exhaust pipe and one end of the air supply pipe are respectively communicated with the oven body. The other end of the exhaust pipe is communicated with the end of the waste gas main pipe. A suction fan is disposed on the part of the waste gas main pipe, between the exhaust pipe and the air supply pipe. The heat recovery device is disposed between the oven body and the exhaust and air supply pipes, and comprises a heat absorption chamber and a heat dissipation chamber. The heat absorption chamber is communicated with the exhaust pipe. The air supply pipe is communicated with the heat dissipation chamber. Heat of the heat absorption chamber and the heat dissipation chamber is conducted through a heat conductor. The circuit board oven has the advantages that the heat is absorbed by the heat absorption chamber, transferred by the heat conductor to the heat dissipation chamber and released; supplied normal-temperature air is heated to increase the temperature of supplied oven gas, constant temperature power consumption is reduced, and heating time is shortened.
