[0045] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Combine the following Figures 1 to 6 The cargo box heating system according to the embodiment of the present utility model is described.

[0047] like Figures 1 to 6 As shown, an embodiment of the utility model provides a cargo box heating system, including a heat source device, a cargo box body and a spoiler 5.

[0048] Specifically, the heat source device is used to provide hot gas.

[0049] The cargo box body has a channel, one end of which is used to be connected to the heat source device, and the other end of the channel is connected to the outside atmosphere.

[0050] After the hot gas generated by the heat source device enters the channel, it circulates in the channel and can transfer its own heat to the cargo box body to increase the temperature of the cargo box body and prevent the water-containing cargo in the cargo box body from freezing and freezing on the cargo box body.

[0051] The spoiler 5 is arranged in the channel, and the spoiler 5 is perpendicular to the extending direction of the channel. The spoiler 5 is provided with a vent hole 6. When the hot gas flows to the spoiler 5, it continues to flow through the vent hole 6.

[0052] In this way, the spoiler 5 has the function of blocking and disturbing the flow of hot gas, which is conducive to the uniform distribution of hot gas in the channel, and slows down the flow speed of hot gas in the channel, ensuring that the heat of hot gas is effectively transferred to the cargo box body. There are multiple spoilers 5, and the multiple spoilers 5 are spaced apart along the extension direction of the channel, so that the utilization rate of heat can be greatly improved, solving the problem of low heat utilization rate when using hot gas to heat the cargo box of a dump truck in the prior art.

[0053] In the embodiment of the utility model, the heat source device includes a fuel tank 1 and a burner 2. The fuel tank 1 is fixedly arranged outside the cargo box body. The burner 2 has a fuel inlet, an air inlet and an outlet. The fuel inlet of the burner 2 is connected to the fuel tank 1, and the fuel in the fuel tank 1 can enter the burner 2. The air inlet of the burner 2 is connected to the outside atmosphere for air to enter the combustion chamber. The fuel and air enter the combustion chamber and burn in the burner 2. The fuel combustion produces a high-temperature mixed gas such as water vapor and carbon dioxide, which is called hot gas. The outlet of the burner 2 is for the hot gas generated by the combustion to be discharged.

[0054] By using the burner 2 as a heat source, a large amount of electric energy is not required in the process of heating the cargo box body, and the restriction of battery power is eliminated, so the heating demand of the dump truck for the cargo box can be well met.

[0055] The burner 2 includes a combustion chamber and a supercharging element. The combustion chamber has an igniter such as a glow plug for igniting fuel. The space in the combustion chamber is provided for fuel combustion. The fuel inlet of the combustion chamber is connected to the fuel tank 1, the outlet of the combustion chamber is connected to the channel, and the air inlet of the combustion chamber is connected to the outside atmosphere.

[0056] It should be noted that the hot gas generated by the burner 2 in this embodiment is only used to heat the cargo box body, and the heat is sufficient to fully meet the heat demand of the cargo box body in an extremely cold environment. Moreover, the heat of the hot gas is directly transferred to the cargo box body, which can fully utilize the heat, with a high utilization rate and high thermal efficiency.

[0057] To ensure the cleanliness of the air entering the combustion chamber, a filter element may be provided at the air inlet of the combustion chamber.

[0058] The boost element is arranged at the air inlet of the combustion chamber. The boost element can increase the pressure of the air entering the combustion chamber, increase the air intake efficiency of the combustion chamber, ensure the full combustion of the fuel in the combustion chamber, reduce the generation of toxic gases such as carbon monoxide, and reduce pollution to the environment.

[0059] In this embodiment, the fuel may be, but is not limited to, diesel, compressed natural gas (CNG) and liquefied natural gas (LNG).

[0060] When compressed natural gas is selected as the fuel, it can be stored in a gas cylinder. That is, the fuel tank 1 includes a gas cylinder, and the outlet of the gas cylinder is connected to the fuel inlet of the burner 2 through a pipeline. The compressed natural gas has a high pressure in the gas cylinder, and the compressed natural gas can flow into the burner 2 under the action of its own pressure.

[0061] A control valve is provided at the outlet of the gas cylinder to control the opening and closing of the outlet of the gas cylinder so as to control the flow of compressed natural gas to the burner 2 as required.

[0062] When diesel or liquefied natural gas is selected as the fuel, it can be stored in a container. It can be understood that the fuel tank 1 includes a fuel tank, and in this case, the heat source device also includes a power pump, which is arranged between the outlet of the fuel tank 1 and the fuel inlet of the burner 2. The power pump can pump the liquid fuel in the fuel tank 1 to the burner 2 when it is running.

[0063] The hot gas has a high temperature. When it flows in the channel, the water vapor in the hot gas condenses into condensed water when it encounters cold, while releasing heat. The heat of other components in the hot gas is transferred to the cargo box body to form low-temperature gas.

[0064] The channel is connected to the outside atmosphere, and the remaining low-temperature gas and condensed water flow to the end of the channel and are discharged into the outside atmosphere.

[0065] In this embodiment, the lower end of the spoiler 5 is arranged in a groove to form a flow space 7 between the lower end of the spoiler 5 and the bottom wall of the channel, which can allow condensed water to flow, ensuring that after the water vapor in the hot gas condenses to form condensed water, it can be discharged in a timely and smooth manner to avoid the accumulation of condensed water.

[0066] In this embodiment, the channel includes a first transverse channel 3 and a first longitudinal channel 4. The first transverse channel 3 extends in the transverse direction of the cargo box body, and the first longitudinal channel 4 extends in the longitudinal direction of the cargo box body.

[0067] At least two first longitudinal channels 4 are provided, and the first end of each first longitudinal channel 4 is connected to the first transverse channel 3. The first transverse channel 3 is connected to the outlet of the burner 2, and the hot gas generated in the burner 2 enters the first transverse channel 3, and then enters the first end of each first longitudinal channel 4 respectively, and flows to the second end of the first longitudinal channel 4.

[0068] The second end of each first longitudinal channel 4 is connected to the outside atmosphere, and the remaining low-temperature gas and condensed water flow to the second end of the first longitudinal channel 4 and can be discharged from the second end of the first longitudinal channel 4 .

[0069] The heat of the hot gas and the condensation heat of the water vapor therein are transferred to the cargo box body through the first transverse channel 3 and the first longitudinal channel 4, and the temperature of the cargo box body is increased, thereby preventing the water-containing cargo in the cargo box body from being frozen on the cargo box body, ensuring that the cargo in the cargo box body can be unloaded smoothly.

[0070] The spoiler 5 is arranged inside at least one of the first transverse channel 3 and the first longitudinal channel 4. Specifically, the spoiler 5 can be arranged only in the first transverse channel 3, or only in the first longitudinal channel 4, or both in the first transverse channel 3 and in the first longitudinal channel 4, which can be determined according to specific circumstances.

[0071] In this embodiment, the cargo box body at least includes a bottom plate 8 , a first cross beam 9 and a longitudinal beam 10 .

[0072] The horizontal direction of the bottom plate 8 is the horizontal direction of the cargo box body. Figure 3 The direction indicated by x in the figure is the longitudinal direction of the bottom plate 8, which is the longitudinal direction of the cargo box body. Figure 3 The bottom plate 8 is generally arranged in a rectangular shape, the width direction of the rectangle is regarded as the lateral direction of the bottom plate 8, and the length direction of the rectangle is regarded as the longitudinal direction of the bottom plate 8.

[0073] The first cross beam 9 and the longitudinal beam 10 are both arranged below the bottom plate 8 to support the bottom plate 8 so as to increase the rigidity of the bottom plate 8 .

[0074] The first cross beam 9 is disposed below the first end of the bottom plate 8 and extends in the transverse direction of the bottom plate 8. The longitudinal beam 10 is disposed below the bottom plate 8 and extends in the longitudinal direction of the bottom plate 8. The first end of the longitudinal beam 10 is connected to the first cross beam 9.

[0075] In some embodiments, the cross section of the first cross beam 9 and the cross section of the longitudinal beam 10 are set to a closed shape. For example, the cross section of the first cross beam 9 is rectangular, in which case the first cross beam 9 has a cavity inside, and the internal cavity of the first cross beam 9 forms the first transverse channel 3. Similarly, the cross section of the longitudinal beam 10 is rectangular, in which case the longitudinal beam 10 has a cavity inside, and the internal cavity of the longitudinal beam 10 forms the first longitudinal channel 4.

[0076] In some other implementations, the cross section of the first cross beam 9 and the cross section of the longitudinal beam 10 are set to an open shape. For example, the cross section of the first cross beam 9 is U-shaped. In this case, the open side of the first cross beam 9 faces the bottom plate 8, so that the first cross beam 9 and the bottom plate 8 are enclosed to form a cavity, and the cavity serves as the first transverse channel 3. Similarly, the cross section of the longitudinal beam 10 is U-shaped. In this case, the open side of the longitudinal beam 10 faces the bottom plate 8, so that the longitudinal beam 10 and the bottom plate 8 are enclosed to form a cavity, and the cavity serves as the first longitudinal channel 4.

[0077] In this case, the hot gas in the first transverse channel 3 and the first longitudinal channel 4 can directly contact the bottom plate 8, which can improve the heat transfer efficiency and the heating efficiency of the cargo box body.

[0078] In this embodiment, at least two longitudinal beams 10 are provided, and each longitudinal beam 10 is spaced apart along the transverse direction of the bottom plate 8, and the first end of each longitudinal beam 10 is fixedly connected to the first cross beam 9.

[0079] An air inlet is provided on the first crossbeam 9, and the air inlet is used to allow hot gas to enter the first transverse channel 3. One air inlet is provided corresponding to each longitudinal beam 10. It can be understood that at least two air inlets are provided on the first crossbeam 9, and hot gas can enter the first transverse channel 3 through different air inlets, which is conducive to the uniform distribution of hot gas in the first transverse channel 3. At the same time, each air inlet is arranged adjacent to the corresponding longitudinal beam 10, which can ensure that the flow rate of hot gas in each first longitudinal channel 4 is consistent, which is conducive to improving the uniform temperature distribution of the bottom plate 8 of the cargo box body along its transverse direction.

[0080] At this time, the cargo box body also includes an intake manifold, which is arranged between the first cross beam 9 and the outlet of the burner 2.

[0081] The design of the intake manifold facilitates even distribution of the hot gas in the main pipeline to each branch pipeline, thereby ensuring uniformity of the hot gas in the first transverse channel 3 and consistency of the flow of the hot gas in each first longitudinal channel 4 .

[0082] In this embodiment, the cargo box body further includes a front plate 18, which is located above the first end of the bottom plate 8, and the lower end of the front plate 18 is connected to the bottom plate 8. The burner 2 is fixed on the front plate 18, and a vent is provided on the front plate 18. The outlet of the burner 2 is connected to the vent on the front plate 18 through a pipeline, and the vent on the front plate 18 is connected to the first end of the main pipeline through a pipeline.

[0083] In the embodiment of the utility model, the cargo box body further includes a pair of side panels 11 and a guide plate 12 .

[0084] A pair of side plates 11 are distributed on both sides of the bottom plate 8 in the transverse direction of the bottom plate 8, and the lower ends of the side plates 11 are connected to the bottom plate 8. Each side plate 11 is provided with a guide plate 12 corresponding to the side plate 11, and the guide plate 12 extends in the longitudinal direction of the bottom plate 8, and the guide plate 12 is inclined relative to the bottom plate 8 and the side plates 11, so that the guide plate 12, the side plates 11 and the bottom plate 8 are enclosed to form a second longitudinal channel 13.

[0086] The second longitudinal channel 13 is combined with the first longitudinal channel 4 to improve the heating effect on the cargo box body.

[0087] In an embodiment of the utility model, the cargo box body also has a second transverse channel 14, which is parallel to the first transverse channel 3, and the second end of each first longitudinal channel 4 and the second end of each second longitudinal channel 13 are connected to the second transverse channel 14, and the remaining low-temperature gas and condensed water in the first longitudinal channel 4 and the remaining low-temperature gas and condensed water in the second longitudinal channel 13 can flow into the second transverse channel 14.

[0089] Correspondingly, the cargo box body further includes a second cross beam 19 , which is disposed below the second end of the bottom plate 8 and extends in the transverse direction of the bottom plate 8 .

[0090] Similar to the first cross beam 9, the cross section of the second cross beam 19 can be set to a closed shape. For example, the cross section of the second cross beam 19 is rectangular, in which case the second cross beam 19 has a cavity inside, and the second cross beam 19 has a cavity inside, forming the second transverse channel 14. The cross section of the second cross beam 19 can also be set to an open shape. For example, the cross section of the second cross beam 19 is U-shaped, in which case the opening side of the second cross beam 19 faces the bottom plate 8, so that the second cross beam 19 and the bottom plate 8 are enclosed to form a cavity, and the cavity serves as the second transverse channel 14.
