Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of examples.
The embodiment provides a heater for a vehicle with a large air intake, which comprises an outer shell 1, an inner shell 2, an oil nozzle 5 and a tail gas spray pipe 6, as shown in fig. 1.
The outer shell 1 comprises a conical section and a cylindrical section, and the large end of the conical section is fixedly connected with the end part of the cylindrical section; the end part of the outer shell 1 is connected with an oil nozzle 5, and an interface of the oil nozzle 5 is arranged on the top surface of the conical section structure. The front part of the cylindrical section of the outer shell 1 is provided with a glow plug interface for installing a glow plug to discharge and ignite.
The inner shell 2 is sleeved in the outer shell 1, the end faces of the inner shell and the outer shell are fixed together by welding through a cover plate, and an air inlet interlayer 7 is formed between the outer shell 1 and the inner shell 2. The tail gas spray pipe 6 is fixed on the cover plate, and the tail gas spray pipe 6 is communicated with the inner shell 2. The one end of the oil nozzle 5 is kept away from to the interior casing 2 and is equipped with the through-hole 8, with the inside intercommunication of air inlet intermediate layer 7 and interior casing 2, the inside combustion chamber that is of interior casing 2.
The side of the conical section of the outer shell 1 is provided with a plurality of air inlet channels 4 for supplying air into the air inlet interlayer 7, namely the air inlet channels 4 are communicated with the air inlet interlayer 7 and are uniformly distributed along the circumferential direction of the side of the conical section. As shown in fig. 2, the air inlet channel 4 is a circular tube 3 extending out of the outer surface of the outer shell 1, and the circular tube 3 is tangent to the outer surface of the outer shell 1 at an angle θ; the angle theta is an included angle formed by the central axis of the air inlet channel 4 and the central axis of the outer shell 1.
