Self-powered fuel air heater

Abstract

The invention provides a self-powered fuel air heater which is formed by combining a thermoelectric assembly and a heat source assembly. The thermoelectric assembly comprises a hot end fin, a semiconductor refrigeration power generation piece, a cold end fin and a second wind scooper. The heat source assembly comprises a first wind scooper, an air fan wheel, a controller, a battery and a combustion unit. The thermoelectric assembly is connected with the heat source assembly, the combustion unit is closely connected to a port of a hot end fin, a combustion cylinder extends into the annular interior of the hot end fin of the thermoelectric assembly to form a combustion chamber, the first wind scooper and the second wind scooper are closely connected and communicated to form an integrated wind guide cavity, and the air guide cavity and the combustion chamber are relatively independent. Finally, the current output by the thermoelectric assembly is connected with the battery and the controller of the heat source assembly to form the integral self-powered fuel air heater. The invention has the beneficial effects that the self-supply and self-sufficiency of the power supply are realized, and the equipment can independently and continuously work without an external power supply, and is not limited by a power supply shortage area any more.

Description

technical field [0001] The technology of the invention relates to the field of heating devices, in particular to a self-powered 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 of trucks, construction machinery, equipment cabins, and passenger cars, and the heating space is generally small. The structure of these fuel heaters is simple, that is, an interlayer channel is arranged on the periphery of the combustion chamber of the combustion unit as a heat exchanger, and cold air can be introduced into it. Exhaust into the heating space, and the exhaust gas from the combustion chamber is discharged to the outside through the exhaust pipe. Due to the low heat exchange efficiency, the temperature of the exhaust gas discharged by the fuel-air heater is as high as more than 100 degrees Celsius, and a large amo...
