Problems solved by technology

Existing heaters generally use glow plugs for preheating. The power of the glow plugs is large, and the glow plugs cannot directly contact the pipelines of the oil system. They can only preheat the air around the pipelines. The diesel in the pipeline forms heat exchange, and the pipeline is made of metal, which dissipates heat quickly, which makes the glow plug preheating efficiency low. To achieve a good preheating effect, it takes a long time and consumes more power.

Embodiment Construction

[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0027] figure 1 Is a front cross-sectional view of an embodiment of the diesel preheating device of the present invention, figure 2 Yes figure 1 Left view. As shown in the figure, the diesel preheating device includes a preheating rod 1, a diesel buffer device 5, and an atomizing nozzle 4. The diesel buffer device 5 is a heat-conducting entity. This embodiment is an aluminum entity because aluminum has high thermal conductivity, The price is cheap, but other thermal conductive materials can also be selected as needed. The diesel buffer device 5 is provided with a diesel flow channel and a p...

Abstract

The invention provides a diesel preheating device. The diesel preheating device comprises a preheater, a diesel storage device and an atomizing nozzle. The diesel storage device is a heat conduction entity, and a diesel flow path is arranged in the diesel storage device. The diesel flow path comprises a diesel inlet and a diesel outlet, the diesel outlet is connected with the atomizing nozzle in a sealing mode, a preheater containing cavity is formed in the diesel storage device, and the preheater is arranged in the preheater containing cavity. According to the diesel preheating device, the preheater is fixed inside the diesel storage device, fixed point preheating technology is adopted, liquid heat exchange principle is applied, and therefore heat exchange efficiency is improved, energy consumption is reduced, diesel can be preheated most efficiently, viscosity of the diesel can be reduced, and flowability of the diesel can be improved.

Description

Technical field [0001] The invention belongs to the technical field of heating and preheating for vehicles, and particularly relates to a diesel preheating device. Background technique [0002] The diesel preheating device of the present invention is mainly used in a heater to preheat the diesel in a low temperature environment, so that the diesel has a better atomization effect when it is sprayed from the atomization nozzle. Existing heaters generally use glow plugs for preheating. The power of the glow plug is large, and the glow plug cannot directly contact the pipeline of the oil system. It can only preheat the air around the pipeline. When the air heats up, it The diesel in the pipeline forms heat exchange, and the pipeline is made of metal material, which dissipates heat quickly, which makes the glow plug preheating efficiency low. To achieve a good preheating effect, it will take a long time and consume more power. . Therefore, how to preheat diesel fuel quickly and with...
