Description

Technical Field

[0001] The utility model relates to an insulating cooling pipeline for a hydrogen fuel engine and a hydrogen fuel vehicle, belonging to the field of hydrogen fuel vehicles. Background Art

[0002] Hydrogen fuel vehicles have obvious advantages in energy conservation and emission reduction, but due to the continuous output of high voltage electricity from hydrogen fuel engines, the whole vehicle is required to take insulation measures. The insulated cooling pipes of traditional hydrogen fuel engines are directly connected from the engine cooling water outlet to the radiator and expansion tank using hoses. Due to the large size of hydrogen fuel engines, it is easy to cause the pipes on both sides of the frame to pass through a small space after being installed in the middle of the frame. The use of hoses to connect takes up a lot of space and is not securely fixed; in addition, the soft hardness and long length of cooling hoses sometimes cannot match the three-dimensional design of the actual vehicle assembly effect, and according to the current operating conditions of the whole vehicle, long-term operation will cause interference and wear of the cooling hoses, causing leakage failures. The hoses are too thick and there are too many of them, and they are crowded together, which is also very unsightly. Summary of the invention

[0003] In view of the problems existing in the prior art, the utility model provides an insulating cooling pipeline for a hydrogen fuel engine and a hydrogen fuel vehicle.

[0014] At least one split pipe clamp is installed on the insulating cooling pipeline for fixing on the vehicle body.

[0015] As an improvement, a fixing bracket is installed on the insulating cooling pipeline, and the fixing bracket is connected to the frame crossbeam.

DETAILED DESCRIPTION

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present application are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0023] like Figure 1 , Figure 2 As shown, an insulating cooling pipeline for a hydrogen fuel engine includes a cooling steel pipe 9, a heat shrinkable plastic pipe 10 and a heat shrinkable plastic thickened pipe 11;

[0024] The two ends of the cooling steel pipe 9 are connected to hoses respectively, and the hoses at both ends are connected to any two of the hydrogen fuel engine 1, the radiator and the expansion water tank, and the cooling steel pipe 9 is used to transport the coolant;

[0025] The heat shrinkable plastic tube 10 is sleeved on the cooling steel tube 9, and the heat shrinkable plastic tube 10 is used to make the insulated cooling pipeline have insulation performance;

[0026] At least one heat-shrinkable plastic thickened tube 11 is sleeved on the heat-shrinkable plastic tube 10 , and a split-type tube clamp 4 is installed on the heat-shrinkable plastic thickened tube 11 , and the insulating cooling pipeline is fixed on the vehicle body through the split-type tube clamp 4 .

[0027] As an improvement of the embodiment, Figure 1 , Figure 2 As shown, both ends of the cooling steel pipe 9 are connected to the rubber hose through clamps 7, which improves the connection stability between the cooling steel pipe 9 and the rubber hose and ensures the normal transportation of the coolant.

[0028] As an improvement of the embodiment, Figure 1 , Figure 2 As shown, the two ends of the cooling steel pipe 9 are respectively provided with limiting bosses 9-1 for connecting the rubber hose, which improves the connection stability between the cooling steel pipe 9 and the rubber hoses at both ends. After the rubber hose and the cooling steel pipe 9 are initially assembled, the rubber hose is fixed to the cooling steel pipe 9 using a clamp 7. Due to the influence of different degrees of violent vibration of the road surface, the rubber hose and the cooling steel pipe 9 may be offset. The role of the limiting boss 9-1 is to prevent the offset between the two. The clamp 7 is fixed at the limiting boss 9-1 near the inner side. In addition, in the process of manufacturing the cooling steel pipe 9, the limiting boss 9-1 can be formed by using conventional bulging equipment and an extrusion process to achieve bulging.

[0029] As an improvement of the embodiment, Figure 1 , Figure 2As shown, after being heated by the heating fan, the heat shrinkable plastic tube 10 is completely attached to and wrapped around the outer wall of the cooling steel pipe 9, ensuring that the insulated cooling pipeline has good insulation performance.

[0030] As an improvement of the embodiment, the two heat-shrinkable plastic thickened tubes 11 are also heated by a heating fan and then fitted and wrapped around the two ends of the heat-shrinkable plastic tube 10. By wrapping the heat-shrinkable plastic thickened tube 11 on the heat-shrinkable plastic tube 10, the wear resistance is enhanced, preventing the split pipe clamp 4 from being directly installed on the heat-shrinkable plastic tube 10 and causing wear, thereby affecting the insulation performance; the heat-shrinkable plastic thickened tube 11 ensures that the split pipe clamp 4 can be normally installed on the insulating cooling pipeline, thereby fastening the insulating cooling pipeline to the vehicle body.

[0031] In addition, the utility model also provides a hydrogen fuel vehicle, on which the insulating cooling pipeline for the hydrogen fuel engine is installed.

[0032] The insulating cooling pipeline 5 of the utility model can be installed between any two of the hydrogen fuel engine, the radiator and the expansion water tank. The pipeline between the hydrogen fuel engine 1 and the radiator is used as an example for explanation below;

[0033] like Figure 3 As shown, the hydrogen fuel engine 1 is connected to a hydrogen fuel engine cooling water inlet hose 3, and the radiator is connected to a radiator cooling water outlet hose 8. The hydrogen fuel engine cooling water inlet hose 3 is connected to one end of a cooling steel pipe 9 in an insulating cooling pipeline 5 through a clamp 7, and the other end of the cooling steel pipe 9 is connected to the radiator cooling water outlet hose 8 through a clamp 7;

[0034] The insulating cooling pipeline 5 includes two heat-shrinkable plastic thickened tubes 11, each of which is equipped with a split pipe clamp 4. The two split pipe clamps 4 connect the insulating cooling pipeline 5 to the body of the hydrogen fuel vehicle.

[0035] In order to further improve the stability of the installation, such as Figure 3 As shown, the insulating cooling pipeline 5 is connected to the fixing bracket 6 by bolts, and the fixing bracket 6 is connected to the frame crossbeam 2 by bolts.

[0036] When in use, the hydrogen fuel engine 1 will generate a large amount of heat energy during the continuous power generation process. The coolant (such as water) flowing through the insulated cooling pipeline 5 circulates between the hydrogen fuel engine, the radiator, and the expansion water tank, taking away the heat generated by the hydrogen fuel engine 1, achieving a cooling effect, allowing the hydrogen fuel engine 1 to operate in the optimal temperature range (50°C-70°C), while also ensuring the stable output of the rated power of the hydrogen fuel engine 1.

[0037] The utility model discloses an insulated cooling pipeline for a hydrogen fuel engine, which adopts a cooling steel pipe connected between the engine cooling water port and the radiator and the expansion water tank to transport the coolant, and a heat shrinkable plastic pipe is set on the cooling steel pipe to realize pipeline insulation;

[0038] The insulated cooling pipeline reduces the diameter of the cooling pipeline, greatly reduces the layout space, and makes the vehicle layout simpler. At the same time, it avoids interference with surrounding components, improves product reliability, and greatly improves aesthetics.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
