Gasoline Air Parking Heater Introduction

Gasoline air parking heater introduction

1、Introduction

The main equipment of Model 2KW air parking heater (hereinafter referred to as the heater) is a small fuel furnace controlled by a single-chip micro- processor. Its furnace body (the heat exchanger) is located in the hood-shape case, which serves as independent air passage. Cold air is sucked into the air passage by the heat supplying fan and blown out when it becomes hot, so as to form another heating system that is independent to the original heating system of the vehicles. In such a way, heat can be supplied by the heater to driver’s cab and passengers’compartment nomatter the engine is working or not working.The schematic diagram is shown in Fig. 1.

The heater is fully automatically controlled. It features in compact structure, easy installation, energy-saving, environmental protection, safety and reliability, easy maintenance, etc.

2、Structures

The structures of the main heater are shown in Fig. 2

Fig.3 is the diagram for structure  of the heater. 

Heat exchanger 1 is the combustion furnace body, made of die-casting aluminum, with radiating fins around and at the rear end. Combustion pipe 3 is installed in the inner cavity. The front of the combustion pipe insert the combustor 4, Fuel comes to the combustor core through the fuel pipe 13 and is ignited by the glow plug 14 after atomization. The flame enters the gap between the inner walls of the furnace body through the rear-end guide pipe of the combustion pipe, The exhaust is discharged through exhaust pipe vent 15. 

The fresh air for supporting combustion of the furnace comes from the supporting air inlet port 12 and is sent to the combustion pipe by the combustion supporting air blades 6 of the fan motor.
