Airtight type fuel air heater

Abstract

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.

Description

technical field [0001] The invention relates to the field of heating devices, in particular to an airtight fuel-air heater. Background technique [0002] At present, most of the fuel air heaters on the market are usually designed with a calorific value lower than 10kw. These low-calorific heaters are often used for heating cabs such as trucks, construction machinery, equipment cabins, and passenger cars. The space for heating is generally small. For For the inflatable tents used when stationed in the field, the space inside the tent is relatively large, and more heat is needed to meet its heating requirements. [0003] In addition, the field tent is closed as a rest and work area, and the closed area is required to heat up quickly and the air is clean. For field work, it is unrealistic for people to rely on electricity and gas combustion for heating, so heating equipment often needs to rely on burning diesel to provide heat, but a large amount of exhaust gas will be generat...

Problems solved by technology

For example, most of the existing fuel-air heaters currently use injection combustion and fuel volatilization combustion. For injection heaters, most of them do not have a separate exhaust gas discharge port, and the exhaust gas will be blown into the air together with the heated air. The heated area will cause pollution. The hot air outlet and return air inlet are often open and cannot be connected to the sealed air duct. Such products are mostly used in factories, farms, and greenhouses.
