The invention relates to an airtight type fuel
air heater. The heater comprises a
machine box shell body, wherein a
cold air inlet is formed in one side face of the
machine box shell body, a hot air outlet is formed in the top surface of the
machine box shell body, an electric part
assembly is arranged in the middle of the machine box shell body, the electrical part
assembly comprises an electrical part mounting board, the electrical part mounting board is provided with a
transformer, a controller, a
rectifier bridge and a filtering
capacitor, a
heater core assembly is arranged at the lower part of the machine box shell body, one end of the
heater core assembly is connected with a fan, the fan is arranged at one end, close to the
cold air inlet, of the
heater core assembly, the other end of the heater core assembly is connected with the hot air outlet through a pipeline, an
oil tank assembly and an
electromagnetic pump assembly are arranged outside the machine box shell body, and the
electromagnetic pump assembly is arranged below the
oil tank assembly. The airtight type fuel
air heater has the beneficial effects that the labor intensity of workers is reduced, the structure of theheater box body is good in overall gas tightness, the heating value is large, the overall stability is good, the
shock resistance is good, the heater can realize
remote operation to facilitate the operation of the personnel.
