Vehicle heater system

Abstract

The invention provides a vehicle heater system. The vehicle heater system comprises a waste heat system, wherein the waste heat system comprises a combustor outer barrel, an air supply mounting base,a pre-mixing ignition chamber and a diffusion combustion chamber; the pre-mixing ignition chamber and a diffusion burner are arranged in the combustor outer barrel, the tail of the diffusion combustion chamber is connected to a waste gas flue, and a heat exchange core body is arranged in a waste gas flue; the heat exchange core body comprises flat pipes, the flowing direction of liquid in the flatpipes is perpendicular to the flowing direction of waste gas, the flat pipes are divided into multiple rows, each row contains the plurality of flat pipes, fins are arranged inside the flat pipes, liquid flow channels in the flat pipes are divided into a plurality of small flow channels, and the hydraulic diameters of the small flow channels in different flat pipes are continuously reduced in thedirection of flowing of the waste gas. According to the vehicle heater system, along the flow direction of the waste gas, the pressure required to be borne in the flat pipes is smaller and smaller, so that the hydraulic diameter can be reduced, the heat exchange area can be increased by reducing the hydraulic radius, and the heat exchange capacity is improved, therefore, through arrangement of the characteristics, the pressure requirement can be met, and the enhanced heat transfer can be realized as well.

Description

[0001] This application is for a divisional application filed on May 22, 2017, with application number 2017103622452, and the title of the invention is "A Premixed Ignition and Diffusion Burner System". technical field [0002] The invention belongs to the technical field of combustion, and in particular relates to a burner for an auxiliary start-up warmer of a power transmission device. Background technique [0003] my country has a vast territory, complex climate and topographical environment, and the power transmission system of special vehicles faces unfavorable factors such as friction pair lockup in extremely cold environments, poor lubrication, reduced battery power supply capacity, and engine ignition difficulties in low-pressure environments, which greatly reduces the reliability of vehicles. sex. As a combustion heat exchange device, the heater transfers heat through the coolant, and can heat the cooling system, lubrication system, transmission system, power system,...
