Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field, specifically relating to a fuel filter heating module. Background Technology
[0002] The main function of a fuel filter is to filter particulate matter, water, and impurities from fuel to protect the delicate components of the fuel system from wear and other damage. Fuel filters are divided into diesel filters, gasoline filters, and natural gas filters, with different types suitable for different fuels.
[0003] Fuel filters can be categorized into diesel filters, gasoline filters, and natural gas filters. Their primary function is to filter particulate matter, water, and impurities from the fuel, ensuring fuel cleanliness and thus protecting the delicate components of the fuel system.
[0004] The replacement interval for fuel filters is generally 48,000 kilometers. Regular inspection and maintenance of the fuel filter can ensure its proper functioning, extend its service life, and keep the fuel system in good condition.
[0005] In existing technologies, the fuel filter installation area is basically exposed without any heating measures. In winter, due to untimely fuel changes or poor fuel quality, the fuel at the fuel filter often waxes, causing fuel line blockage, affecting the heater's start-up and normal operation, thus affecting heating or engine starting. In addition, every time the fuel in the fuel filter waxes in winter, the filter element needs to be replaced before starting the heater, causing considerable trouble and loss. Utility Model Content
[0006] Purpose of the utility model: To provide a fuel filter heating module to solve the problems mentioned above.
[0007] Technical solution: A fuel filter heating module, comprising: an aluminum heating core, an outer shell, a top cover, and a protective sleeve;
[0008] In a further embodiment, the aluminum shell heating element is wrapped around the outside of the fuel filter and installed inside the housing. The top cover is fixedly installed on the top of the housing to fix the aluminum shell heating element and the fuel filter inside the housing and the top cover. The aluminum shell heating element is provided with a PTC heating element. The PTC heating element is connected to the sheath through a wire. The sheath is placed outside the housing.
[0009] In a further embodiment, the upper cover has a lead hole through which the wire is led out.
[0010] In a further embodiment, the exposed outer area of the conductor is wrapped with a corrugated tube, which secures the conductor between the outer shell and the sheath via heat-shrink tubing.
[0011] In a further embodiment, the outer casing and the upper cover are fixedly connected by mounting screws.
[0012] In a further embodiment, the aluminum housing heating core is provided with a tightening screw to control the tightness of the aluminum housing heating core surrounding the fuel filter.
[0013] Beneficial effects: This utility model wraps the fuel filter with an aluminum shell heating core, and then conducts heat to the fuel filter through the PTC heating element inside the aluminum shell heating core, thereby melting the waxy fuel inside the fuel filter in a short time. The outer shell and the top cover play a heat preservation role, opening up the oil passage and restoring the heater's fuel supply. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] A fuel filter heating module includes: a fuel filter 1, an aluminum heating core 2, an outer shell 3, a top cover 4, a heat shrink tubing 5, a corrugated tube 6, a sheath 7, mounting screws 8, tightening screws 9, and a wire 10.
[0022] Example 1:
[0023] In one embodiment, such as Figures 1 to 3 As shown, the aluminum shell heating core 2 is wrapped around the outside of the fuel filter 1 and installed inside the outer shell 3. The upper cover 4 is fixedly installed on the top of the outer shell 3 to fix the aluminum shell heating core 2 and the fuel filter 1 inside the outer shell 3 and the upper cover 4. The aluminum shell heating core 2 is provided with a PTC heating element. The PTC heating element is connected to the sheath 7 through the wire 10. The sheath 7 is placed outside the outer shell 3.
[0024] In one embodiment, such as Figures 1 to 3 As shown, the upper cover 4 has a lead wire hole, through which the wire 10 is led out.
[0025] In one embodiment, such as Figures 1 to 3 As shown, the exposed outer area of the conductor 10 is wrapped with a corrugated tube 6, and the corrugated tube 6 fixes the conductor 10 between the outer shell and the sheath 7 through a heat shrink tube 5.
[0026] In one embodiment, such as Figures 1 to 3 As shown, the outer shell 3 and the upper cover 4 are fixedly connected by assembly screws 8.
[0027] In one embodiment, such as Figures 1 to 3 As shown, the aluminum shell heating core 2 is provided with a tightening screw 9 to control the tightness of the aluminum shell heating core 2 encasing the fuel filter 1.
[0028] Example 2:
[0029] In one embodiment, such as Figures 1 to 3As shown, the assembly steps of this utility model are as follows: The PTC heating element is placed inside the aluminum shell heating core 2 and connected by the wire 10. The aluminum shell heating core 2 wraps the fuel filter 1 and is then installed inside the outer shell 3 and the upper cover 1. The wire 10 is led out through the hole in the upper cover 4. The assembly screw 8 reliably connects the outer shell 3 and the upper cover 4. The tightening screw 9 tightens the aluminum shell heating core 2 so that the aluminum shell heating core 2 is in close contact with the outer surface of the fuel filter 1. The led-out wire 10 is protected by the corrugated tube 6 and inserted into the sheath 7, and then protected and fixed by the heat shrink tubing 5.
[0030] In one embodiment, such as Figures 1 to 3 As shown, the outer shell 3 and the upper cover 1 are made of PA6-RG301, which can provide good heat insulation.
[0031] Working principle: After the protective sleeve 7 is connected to the power supply, the PTC heating element starts to heat up and conducts the heat to the aluminum shell heating core 2. The aluminum shell heating core 2 then conducts the heat to the fuel filter 1. After reaching a certain temperature, the waxy fuel in the fuel filter 1 can be melted. At the same time, the outer shell 3 and the top cover 4 can play a heat preservation role.
[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
