Heating device of diesel oil filter

Abstract

The invention discloses a heating device of a diesel oil filter. In a technical scheme provided by the invention, the heating device of the diesel oil filter comprises a heating base and a shunting device, wherein the heating base is internally provided with a heating pipe; by means of a heat exchange effect between ceaseless hot water in the heating pipe and diesel oil in an oil filter shell, the temperature of the diesel oil to be introduced into an engine combusting system is increased, so that high-grade fuel oil under a low-temperature environment can be prevented from the phenomena of thickness and even wax precipitation to block a filter screen. The heating base not only has a heating function but also has sealing, mounting and other functions as common filter top cover. The heating device disclosed by the invention has the advantages of ingenious conception, simple structure, good sealing performance, low cost, superior performance, convenience in use, energy-saving and emission-reduction performance, and the like.

Description

technical field [0001] The invention relates to a heating device for a diesel oil filter, which belongs to the field of diesel oil filters for motor vehicles. Background technique [0002] In cold regions, due to the influence of the ambient temperature, the diesel oil in the diesel filter will become less fluid due to the increase in viscosity, and even wax will clog the filter screen, resulting in difficulty in starting and sudden flameout during driving. In order to avoid this phenomenon, people often need to use low-grade low-temperature oil. However, low-grade diesel is not only expensive, but also accompanied by a decrease in power, which adds a lot of economic burden to motor vehicle users. [0003] In order to be able to continue to use high-grade diesel oil, one solution is to use electric heating. This method is not only complicated in process and expensive, but also has the danger of fire caused by improper power distribution, and it needs to consume energy alread...

AI Technical Summary

Problems solved by technology

[0002] In cold regions, subject to the influence of ambient temperature, the fluidity of the diesel oil in the diesel filter becomes poor due to the increase of viscosity, and even the wax deposits to block the filter screen, causing troubles such as difficulty in starting and sudden flameout during driving.

In order to avoid this phenomenon, people often need to use low-grade low-temperature oil. However, low-grade diesel is not only expensive, but also accompanied by a decrease in power, which adds a lot of economic burden to motor vehicle users.

[0003] In order to be able to continue to use high-grade diesel oil, one solution is to use electric heating. This method is not only complicated in process and expensive, but also has the danger of fire caused by improper power distribution, and it needs to consume energy already in a low-temperature environment. The power of the storage battery is severely reduced; there is also a solution to set a heating water jacket outside the filter, which has a low heat utilization rate
