Methyl alcohol heater

Abstract

The invention discloses a methyl alcohol heater. The methyl alcohol heater comprises a machine body, wherein an air inlet is formed in one end of the machine body; a pre-combustion chamber is arrangedat the other end of the machine body; the pre-combustion chamber is arranged in a heat exchanger, and communicates with a main combustion chamber in the heat exchanger; an air exhaust hoe is formed in the heat exchanger; a heat exchange medium outlet of the heat exchanger is connected with a heating medium inlet of a radiator in a car; a heat exchange medium inlet of the heat exchanger is connected with one end of a circulating pump; the other end of the circulating pump is connected with a heating medium outlet of the radiator in the car; a fuel pump used for providing methyl alcohol is arranged between a position, at the air inlet, in the machine body and a pre-combustion chamber; a liquid outlet end of the fuel pump is connected with a spray nozzle; and an ignition electrode is arranged on a position, close to the spray nozzle, in the machine body. The methyl alcohol heater does not affect vehicle endurance mileage, is simple and compact in structure, and has the characteristics ofbeing sufficient in combustion and good in environment friendliness; and according to a test, content of emission pollutants of the methyl alcohol heater is only 1 / 3-1 / 2 that of the fuel oil heater,so that smoke is not generated during starting and stopping.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a methanol heater. Background technique [0002] A car refers to a vehicle that is driven by a vehicle-mounted power supply and driven by a motor to drive the wheels, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. [0003] At present, the heating source of large vehicles such as electric buses and electric passenger cars mainly uses fuel heaters or electric heaters. However, fuel heaters have the problem of high pollutant emissions, especially when starting or stopping. The discharge of pollutants is relatively large, and the change of smoke can be clearly seen by the naked eye. It is particularly inconvenient that when the temperature changes, different brands of diesel oil need to be replaced; although the electric heater solves the problem of high pollutant d...

Problems solved by technology

[0003] At present, the heating source of large vehicles such as electric buses and electric passenger cars mainly uses fuel heaters or electric heaters. However, fuel heaters have the problem of high pollutant emissions, especially when starting or stopping. The discharge of pollutants is relatively large, and the change of smoke can be clearly seen by the naked eye. It is particularly inconvenient that when the temperature changes, different brands of diesel oil need to be replaced; although the electric heater solves the problem of high pollutant discharge in the fuel heater , but it increases the electricity load, which will affect the cruising range to a certain extent; in addition, the existing methanol-fueled vehicles use methanol as fuel. Engine preheating, improving the adaptability of methanol fuel vehicles, urgently needs to be solved
