DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] like Figures 1 to 8 As shown, a combined water bath gasifier for new energy vehicles includes a bottom cover 10, the upper part of the bottom cover 10 is sealed and connected to an external shell 7, four external connecting columns 901 are fixedly connected inside the external shell 7, the length of the four groups of external connecting columns 901 is shorter than the length of the external shell 7, the inner side of the four groups of external connecting columns 901 is fixedly connected to an internal shell 9, the internal shell 9 is suspended inside the external shell 7, the internal shell 9 is a multi-layer structure, and the internal shell 9 is provided with a first air inlet 903, a first water inlet 905, a second air inlet 904, a fourth water inlet 910, and a third water inlet 908 from the outside to the inside. The advantage of such a design is that hot water can fully surround the first air inlet 903 and the second air inlet 904 in the internal shell 9, so that the fuel is heated more evenly and can be gasified in a short time.

[0032] like Figure 3As shown, the upper part of the first air inlet 903 and the second air inlet 904 are sealedly connected with an upper end cover 902, and the lower part is sealedly connected with a lower end cover 909. The upper end cover 902 and the lower end cover 909 are provided with openings for water to pass through. The first air inlet 903 is sealedly connected with multiple groups of staggered partitions 11 inside. The partitions 11 include partitions 1 and 2. The upper part of partition 1 is sealedly connected with the upper end cover 902, and the bottom of partition 2 is sealedly connected with the lower end cover 909. The partitions 1 and 2 separate the first air inlet 903 into two groups of "S"-shaped channels, as shown in FIG. Figure 8 As shown, after the fuel enters from the air inlet end 3, the two sets of "S"-shaped channels can flow to the air outlet end 4 at the same time, which not only ensures the heat exchange between the fuel and the hot water, but also increases the gasification area so that the gasified fuel at the air outlet end 4 is sufficient. The second air inlet 904 is sealed with four sets of connecting columns 911, which are respectively sealed with the upper end cover 902 and the lower end cover 909. The four sets of connecting columns 911 evenly divide the second air inlet 904 into four sets of independent chambers, which are respectively connected to the first air inlet 903 through pipes. An internal connecting column 907 is fixedly connected to one side of the second air inlet 904, and the inner side of the internal connecting column 907 is sealed and connected to the third water inlet 908. The function of the second air inlet 904 is to assist the first air inlet 903 in fully gasifying the fuel, increase the heat exchange area between the fuel and the hot water, and improve the heat exchange efficiency, so that the fuel can be gasified in a short time.

[0033] like Figure 2 As shown, the upper and lower sides of the outer shell 7 are sealed with an air inlet end 3 and an air outlet end 4, and the inner sides of the air inlet end 3 and the air outlet end 4 are sealed with the inner shell 9 and are respectively connected to the two ends of the "S"-shaped channel in the first air inlet duct 903.

[0034] like Figure 2As shown, one group of chambers in the second air inlet 904 is connected to the air inlet end 3, and the chamber on the opposite side is connected to the air outlet end 4. The two side partitions 11 in the first air inlet 903 that are connected to the air outlet end 4 are sealed with the upper end cover 902. The advantage of this design is that when the fuel finally flows from the first inlet to the air outlet end 4, the vaporized fuel flows upward from the bottom of the first air inlet 903 to the air outlet end. In this process, the chamber connected to the air outlet end 4 increases the air outlet area, which can ensure that sufficient gas flows to the air outlet end 4. The two side partitions 11 in the first air inlet 903 that are connected to the air inlet end 3 are sealed with the lower end cover 909. The advantage of such a design is that the first fuel to enter the first air inlet 903 from the air inlet end 3 is liquid fuel, and the chamber connected to the air inlet end 3 can vaporize the fuel synchronously with the first air inlet 903, and the fuel that is vaporized first will flow along the "S"-shaped pipe inside the first air inlet 903 to the air outlet end 4, ensuring that each chamber can vaporize the fuel and making full use of the internal space of the first air inlet 903 and the second air inlet 904.

[0035] The upper and lower sides of the outer shell 7 are respectively sealed with a water inlet end 1 and a water outlet end 2 for facilitating water inlet and outlet, and the water inlet end 1 and the water outlet end 2 are respectively connected to the second water inlet channel 906.

[0036] The top of the external shell 7 is sealed with a top cover 8, and the bottom of the external shell 7 is sealed with a bottom cover 10. The bottom of the bottom cover 10 is fixedly connected with a first mounting base 5 and a second mounting base 6, so that the utility model is vertically mounted on the vehicle body.

[0037] The first water inlet 905 , the second water inlet 906 , the third water inlet 908 and the fourth water inlet 910 are interconnected, the bottom of the third water inlet 908 is flush with the bottom of the internal connecting column 907 , and the height of the third water inlet 908 is lower than the height of the internal connecting column 907 .

[0038] In the utility model, the outer surface of the outer shell 7 and the first mounting base 5 and the second mounting base 6 are made of stainless steel. The stainless steel material ensures that the shell will not be corroded, thereby increasing the service life of the product. The interior of the outer shell is made of polytetrafluoroethylene material. The polytetrafluoroethylene material is resistant to high and low temperatures and corrosion, and has thermal insulation properties, which can ensure that heat will not be dissipated. The inner shell 9 is made of aluminum. Aluminum has the characteristics of high thermal conductivity and corrosion resistance, thereby increasing the heat exchange efficiency.

[0039] Working process of this utility model:

[0040] The water inlet 1 on the outer shell 7 is connected to the hot water circuit of the cooling water tank, the water outlet 2 on the outer shell 7 is connected to the engine cooling water pipe, the air inlet 3 is connected to the liquid outlet of the vehicle bottle, and the air outlet 4 is connected to the gas inlet of the engine. After the engine is started, the hot water in the engine cooling water tank flows into the new energy vehicle combined water bath vaporizer through the water inlet 1. The hot water enters the first water inlet 905, the second water inlet 906, the third water inlet 908 and the fourth water inlet 910 inside the outer shell 7 at the same time, and the first air inlet 903 and the second air inlet 904 in the inner shell 9 are surrounded by hot water. The inner shell 9 is made of aluminum, has a high thermal conductivity, and is not easily corroded.

[0041] The fuel at the other end also starts to flow from the inside of the air inlet end 3 to the first air inlet duct 903. Because there are multiple groups of staggered partitions 11 inside the first air inlet duct, the fuel flows synchronously in an "S" shape on both sides of the first air inlet duct 903 to the air outlet end 4. During the flow, it passes through the second air inlet duct 904, and the second air inlet duct 904 can also participate in the heat exchange. Finally, the liquid fuel flows out of the air outlet end 4 in the form of gas fuel.

[0042] like Figure 3 As shown, it is worth noting that the upper end cover 902 not only seals the first air inlet 903 and the second air inlet 904 at the top, but also has a part connected to the internal connecting column 907. The upper end of the third water inlet 908 is slightly lower than the internal connecting column 907 and the fourth water inlet 910. Therefore, when hot water flows upward from the bottom of the water bath vaporizer, the water inside the fourth water inlet 910 will hinder the water inside the third water inlet 908, delaying the flow of water from the device, which can ensure that the heat is accumulated higher here, and the liquid in the first air inlet 903 and the second air inlet 904 will vaporize faster. When the liquid part in the first air inlet 903 and the second air inlet 904 is not completely vaporized, it will fall to the bottom of the first air inlet 903 and the second air inlet 904 under the influence of gravity and re-perform the vaporization process. The vaporized fuel will enter the engine along the outlet end 4 at the top of the internal shell 9 for combustion. The new energy vehicle combined water bath gasifier can fully gasify the inflowing liquid, improve combustion efficiency, save energy, and improve economic benefits.

[0043] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
