Channel type and static heating combined fuel oil heating structure

Abstract

The invention discloses a channel type and static heating combined fuel oil heating structure. The channel type and static heating combined fuel oil heating structure comprises a middle vertical platewith an arc-shaped horizontal section, wherein the surface of the side, facing the circle center of the fuel oil heating structure, of the middle vertical plate serves as the inner surface, and the surface of the other side serves as the outer surface; an inner heat dissipation plate and an outer heat dissipation plate are fixedly connected to the inner surface and the outer surface of the middlevertical plate in an attached mode, an upper support plate is connected to the top end of the middle vertical plate, a lower support plate is connected to the lower end of the middle vertical plate,and the upper support plate and the lower support plate are used for being connected with the inner surface of a shell of the fuel filter in a pressing mode, so that a gap is formed between the outerheat dissipation plate and the inner wall of the shell of the fuel filter, the shell is prevented from being heated directly, heat dissipated to the outside is reduced, and the fuel oil heating efficiency is improved. After the channel type and static heating combined fuel oil heating structure is adopted, a heating mode of combining channel type heating and static heating is realized, the heatingefficiency is higher, the energy loss is little, fuel oil at a channel is heated more uniformly, the fuel oil at the channel and static fuel oil are both heated, and the filter resistance when the fuel oil passes through a filter layer is reduced to the maximum extent while the energy is saved.

Description

technical field [0001] The invention relates to the technical field of a fuel filter system for vehicles, in particular to the technology for heating the fuel inside the filter. Background technique [0002] The fuel filter is an important part of the engine fuel system. Its function is to filter out impurities, water and other pollutants in the fuel, provide clean fuel, prevent rust and blockage of the fuel injector, and avoid accumulation in the combustion chamber of the engine. carbon, thereby ensuring the normal operation of the fuel system, improving reliability and extending the service life of the engine. [0003] The lower the fuel temperature, the greater the viscosity and the greater the resistance when passing through the filter element. Therefore, in order to reduce the filter resistance of the filter element to the fuel, it is necessary to heat the fuel. [0004] The electric heater in the traditional fuel filter structure has three typical structures, namely:...

Problems solved by technology

[0007] The disadvantage of this method is that due to the slow heat conduction process, when the engine is just started, the fuel near the filter layer is not heated, resulting in a large filter resistance of the filter element to the fuel.

[0008] The former method realizes channel heating and static heating respectively, but the disadvantage is that the initial heating effect is poor

[0009] 3. Heating on the outside of the filter layer, see Chinese patent 201721433468.5. Although this method can heat the fuel near the filter layer, it can only be close to the structure of the inner wall of the filter shell, resulting in a lot of heat being absorbed by the filter shell. Take away, high energy waste rate

[0010] For this reason, it is urgent to provide a structure to solve the problems of slow heating and low energy utilization.
