Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to heating devices, heating systems and vehicles. Background Technology

[0002] A vehicle may include a body and a heating system located inside the body. The body is used to carry people or goods, and the heating system is used by the people inside the vehicle to heat items such as food.

[0003] In the prior art, the heating system uses the coolant in the engine's cooling system to heat the food, but the heating temperature is low and the heating time is long, resulting in low heating efficiency and affecting the taste of the food. Utility Model Content

Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0033] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0035] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, the range of which is within an acceptable deviation range, said acceptable deviation range being determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system).

"Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0036] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. This application provides a vehicle 1000, which can be a pure gasoline vehicle, a pure electric vehicle, a hybrid electric vehicle, etc. The vehicle 1000 can also be a sedan, bus, truck, trailer, etc.

[0037] The vehicle 1000 may include a body and a heating system 100 located inside the body. The body is used to carry people or goods, and the heating system 100 is used by the people inside the vehicle to heat items such as food.

[0038] This application uses vehicle 1000 as an example to illustrate a hybrid electric vehicle.

[0039] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a heating system 100 provided in some embodiments of this application. The heating system 100 may include an exhaust device 2 of an engine and a heating device 1, with the heat dissipation pipe of the heating device 1 connected to the exhaust device 2.

[0040] In this way, by connecting the heat dissipation pipe to the exhaust device 2 and the heating device 1, the heat of the exhaust gas in the exhaust device 2 can be recovered. The temperature of the exhaust gas can instantly reach more than 400°C. The heat of the exhaust gas can be reused for cabin heating or battery preheating, reducing additional energy consumption and improving heating efficiency.

[0041] In some embodiments, the exhaust system 2 is located in the front compartment. Coupled with the engine, the exhaust system 2 is highly integrated with the engine, which reduces resistance in the waste heat recovery piping system compared to a conventional exhaust system located under the trunk.

[0042] In some embodiments, the heating box 12 of the heating device 1 is located in the armrest box between the driver's seat and the passenger seat.

[0043] In this way, by placing the heating box 12 in the armrest box between the driver's seat and the passenger seat, the space occupied by the heating box 12 in the front compartment can be reduced, and since the exhaust device 2 is also located in the front compartment, the heat transmission path of the high-temperature exhaust gas can be shortened.

[0044] In some embodiments, along the exhaust direction of the exhaust device 2, the position of the air inlet 11A connected to the heat dissipation pipe on the exhaust device 2 is located upstream of the position of the exhaust end 11B connected to the heat dissipation pipe on the exhaust device 2.

[0045] In this way, the high-temperature exhaust gas in the exhaust device 2 can quickly enter the air inlet 11A of the heat dissipation duct, significantly shortening the start-up time for cabin heating or battery preheating. Using engine exhaust gas as a heat source means that once the engine starts, the exhaust gas temperature immediately reaches the required heating temperature, offering advantages such as time stability and no vacuum period due to heat source deficiency. Furthermore, the heat source is gaseous, resulting in low system resistance, rapid diffusion, and no risk of leakage to the passenger compartment. However, using the heat from the engine cooling water for food heating has a failure mode lasting approximately a few minutes. Also, once the engine is running stably and can provide heating to the passenger compartment, the heating device 1 utilizes the cooling water, causing a diversion of some flow and increasing system circulation resistance.

[0046] In some embodiments, please refer to Figure 3 and Figure 4 , Figure 3 for Figure 2 The diagram shows a top view of the heating system 100. Figure 4 for Figure 2 The diagram shows the structure of the exhaust device 2 in the heating system 100. The exhaust device 2 includes an exhaust gas assembly 21 and an exhaust tailpipe connected to the outlet of the exhaust gas assembly 21. The heat dissipation pipe of the heating device 1 is connected between the outlet of the exhaust gas assembly 21 and the exhaust tailpipe.

[0047] In this way, by connecting the heat dissipation pipe between the outlet of the exhaust gas assembly 21 and the exhaust tailpipe, the heat of the exhaust gas in the exhaust device 2 can be recovered for cabin heating or battery preheating, reducing additional energy consumption.

[0048] In some embodiments, the heating system 100 may further include a power battery that provides high-voltage electricity to heat items within the heating device 1 via a high-voltage wiring harness.

[0049] Please see Figure 5 , Figure 5 for Figure 3 The diagram shows an exploded view of the heating device 1 in the heating system 100. The heating device 1 is applied to a vehicle 1000. The heating device 1 may include a heating box 12 and a radiator 13. The radiator 13 is disposed on the wall of the heating box 12 and includes heat dissipation pipes adapted to connect to the exhaust device 2 of the engine of the vehicle 1000.

[0050] In this way, by connecting the radiator 13 to the exhaust system 2 of the engine of the vehicle 1000, and with the exhaust system 2 located in the front compartment, the exhaust gas from the engine exhaust system 2 can be directly transferred to the wall of the heating box 12 through the heat dissipation pipe. Compared to using the coolant in the engine's cooling system to heat food, where the coolant temperature needs to reach above 80°C, the exhaust gas temperature can instantly reach 400°C, which can directly heat and cook the food inside the heating box 12, or sterilize related containers (such as baby bottles, tableware, etc.), thereby reducing the heat loss of exhaust gas circulation in the heating system 100 and improving the heating efficiency of the heating device 1.

[0051] In addition, this arrangement allows the structure of the radiator 13 to be more compact, thereby reducing the volume of the heating device 1 and further reducing the space occupied by the heating device 1 in the heating system 100.

[0052] In some examples, the radiator 13 may be located on the side wall of the heating chamber 12, or the radiator 13 may be located on the top wall of the heating chamber 12.

[0053] In some examples, the number of heat dissipation pipes can be multiple, such as 2, 4, 6, etc.

[0054] In some embodiments, the heat dissipation pipe includes an air inlet 11A and an air outlet 11B, both of which are adapted to be connected to the exhaust device 2.

[0055] In this way, by connecting both the air inlet 11A and the exhaust 11B of the heat dissipation pipe to the exhaust device 2, a closed loop can be formed between the heating device 1 and the exhaust device 2. The exhaust gas in the exhaust device 2 is left to the heat dissipation pipe through the air inlet 11A to heat and cook the food inside the heating box 12, or to disinfect the relevant containers. After the exhaust gas is utilized, it is discharged through the exhaust 11B, realizing the rapid recovery and reuse of waste heat and reducing heat waste.

[0056] In some examples, the intake end 11A and the exhaust end 11B can both be connected to the same side of the exhaust device 2. In other examples, the intake end 11A and the exhaust end 11B can be connected to both sides of the exhaust device 2, both of which can realize the rapid recovery and reuse of waste heat from exhaust gas.

[0057] This application is illustrated by way of example, with the intake end 11A and the exhaust end 11B being able to be connected to both sides of the exhaust device 2.

[0058] In some embodiments, the heating device 1 further includes a flow regulating device 14, which is disposed at the air inlet 11A and / or the exhaust 11B. That is, the flow regulating device 14 may be disposed at the air inlet 11A, or at the exhaust 11B, or at both the air inlet 11A and the exhaust 11B.

[0059] In this way, by setting the flow regulating device 14 at the inlet end 11A and / or the outlet end 11B, the input amount of high-temperature exhaust gas into the heating device 1 can be dynamically adjusted by the flow regulating device 14. Combined with the reverse adjustment at the outlet end 11B, local overheating or heat waste can be prevented, so as to maximize the utilization of exhaust gas heat and improve heating efficiency.

[0060] This application is illustrated by way of example, with the flow regulating device 14 being provided at the intake end 11A and the exhaust end 11B.

[0061] In some embodiments, the flow regulating device 14 can be a control valve, which can be opened and closed. The control valve can be a proportional valve or a servo valve, etc., and this application does not limit it. It is understood that the control valve can adjust the intake and exhaust volume of the exhaust gas according to actual needs to achieve the temperature required by the user. For example, the control valve can be in a fully open, fully closed, half open, or half closed state.

[0062] Specifically, when the user needs to maintain a high temperature range (e.g., around 100℃), the flow regulating device 14 increases the intake opening to increase the intake volume and decreases the outlet opening to reduce the output volume, allowing the radiator 13 to fully exchange heat to meet the user's needs. When the user needs to maintain a medium temperature range (e.g., around 70℃), the flow regulating device 14 maintains a low opening to reduce the intake volume and the outlet opening to reduce the output volume. When the user needs to maintain a low temperature range (e.g., 40-50℃), the user can maintain a low opening to reduce the intake volume and increase the outlet opening to increase the output volume. When the user does not need to turn on the heating, the flow regulating device 14 is turned off, and the exhaust gas is discharged directly from the exhaust device 2 without passing through the heating system 100.

[0063] In some other examples, the flow regulating device 14 can be a butterfly valve, which can also regulate the intake and exhaust volume of the exhaust gas.

[0064] In some embodiments, the heating device 1 may further include an electric heating component 15, which is disposed on the wall of the heating chamber 12.

[0065] In this way, by placing the electric heating element 15 on the wall of the heating chamber 12, the heat from the exhaust gas of the exhaust device 2 can be transferred to the electric heating element 15, enabling rapid heating of the electric heating element 15. This allows for heating and cooking of food inside the heating chamber 12, or sterilization of related containers, thus improving heating efficiency. Furthermore, this arrangement allows for a more compact structure of the electric heating element 15, thereby reducing the volume of the heating device 1 and further minimizing the space occupied by the heating device 1 within the heating system 100.

[0066] In some examples, the electric heating component 15 may be located on the top wall of the heating chamber 12, or the electric heating component 15 may be located on the side wall of the heating chamber 12.

[0067] In some embodiments, the electric heating assembly 15 may include a resistance wire.

[0068] In this way, the heat from the exhaust gas in the engine's exhaust system 2 can be quickly transferred to the food inside the heating box 12 through the resistance wire, and the heating is uniform. In addition, the resistance wire has a low cost.

[0069] In some examples, the electric heating component 15 can also be an electric heating tube, an electric heating film, an electric heating plate, a heating core, etc.

[0070] In some embodiments, the heating box 12 includes an inner liner 121 and an outer shell 122 disposed outside the inner liner 121, with a radiator 13 and an electric heating assembly 15 disposed between the inner liner 121 and the outer shell 122.

[0071] In this way, by placing the radiator 13 and the electric heating component 15 between the inner liner 121 and the outer shell 122, the heat from the exhaust gas can be quickly transferred to the inner liner 121, shortening the thermal response time. In addition, this arrangement can effectively isolate the electric heating component 15 from the external environment, reducing the risk of leakage and short circuit.

[0072] In some embodiments, the inner liner 121 may be an inner liner side frame 1211 and an inner liner bottom plate 1212; the outer shell 122 may be an outer shell side frame 1221 and a base 1222, with the outer shell side frame 1221 located on the outer periphery of the inner liner side frame 1211, the base 1222 located on the outer side of the inner liner bottom plate 1212, the radiator 13 located between the inner liner bottom plate 1212 and the base 1222, and the electric heating assembly 15 located between the outer shell side frame 1221 and the inner liner side frame 1211.

[0073] In this way, by placing the radiator 13 between the inner liner bottom plate 1212 and the base 1222, the stability of the connection between the radiator 13 and the inner liner bottom plate 1212 and the base 1222 can be improved. Furthermore, since both the outer shell 122 and the base 1222 are made of heat-insulating material, heat transfer from the radiator 13 to the base 1222 is blocked, preventing the base 1222 from aging due to prolonged high temperatures and heat loss. This allows for heating and cooking of food inside the heating chamber 12, or sterilization of related containers. By placing the electric heating component 15 between the outer shell side frame 1221 and the inner liner side frame 1211, heat can be directly transferred to the inner liner side frame 1211, avoiding the vertical temperature gradient caused by traditional bottom-concentrated heating, resulting in a more uniform temperature distribution on the inner liner side frame 1211. In addition, this arrangement allows for a more compact structure of the inner liner 121 and the outer shell 122, thereby reducing the volume of the heating device 1 and further reducing the space occupied by the heating device 1 in the heating system 100.

[0074] In some examples, the radiator 13 can be a copper tube finned radiator, which heats the surrounding cold air through its corrugated aluminum fins. Combined with the low density of hot air and its upward movement, efficient heating can be achieved without the need for additional forced convection devices. Compared with the prior art, which requires the use of fans to enhance the convection heat transfer effect, this reduces the cost of the heating device 1, reduces the space occupied by the heating device 1 in the heating system 100, and also avoids the generation of noise.

[0075] In some examples, the radiator 13 can also be a steel finned radiator, an aluminum finned radiator, a composite material radiator, etc.

[0076] In some embodiments, the bottom plate of the inner liner 121 is provided with a heat-conducting through hole 1212A, and the axial direction of the heat-conducting through hole 1212A is parallel to the bottom plate of the inner liner 121.

[0077] In this way, by aligning the axial direction of the heat conduction hole 1212A with the bottom plate of the inner liner 121, the heat from the exhaust gas can be transferred to the bottom plate of the inner liner 121 more quickly, thereby making the air distribution after heating by the radiator 13 more uniform, so that the food inside the heating box 12 is heated evenly.

[0078] In some examples, the number of thermally conductive vias 1212A can be one, or the number of thermally conductive vias 1212A can be multiple.

[0079] In some embodiments, the inner liner 121 further includes a thermal insulation material 1213, which is disposed between at least a portion of the electric heating assembly 15 and the side frame of the outer shell 122; and / or, the thermal insulation material 1213 is disposed between at least a portion of the radiator 13 and the base 1222. That is, the thermal insulation material 1213 may be disposed between at least a portion of the electric heating assembly 15 and the side frame of the outer shell 122; or, the thermal insulation material 1213 may be disposed between at least a portion of the radiator 13 and the base 1222; or, the thermal insulation material 1213 may be disposed between at least a portion of the electric heating assembly 15 and the side frame of the outer shell 122, and between at least a portion of the radiator 13 and the base 1222.

[0080] This application illustrates by way of example that insulation material 1213 can be provided between at least a portion of the electric heating component 15 and the side frame of the housing 122, and between at least a portion of the radiator 13 and the base 1222.

[0081] Specifically, the outer side of the insulation material 1213 is the outer shell 122, which is arranged in a stepped manner, making the structure of the outer shell 122 more compact, thereby reducing the volume of the heating device 1 and further reducing the space occupied by the heating device 1 in the heating system 100, and adapting to the overall vehicle structure.

[0082] In this way, the diffusion of high-temperature exhaust gas into the external environment can be reduced, or it can overflow into the passenger compartment, creating additional load, or it can be transferred downwards to the base 1222, preventing the base 1222 from overheating and causing a decrease in the stability of the heating device 1. This increases the heat of the inner liner 121 and further improves the heating efficiency of the heating device 1.

[0083] In some examples, the insulation material 1213 can be high-temperature thermal insulation cotton, while in other examples, the insulation material 1213 can be rock wool, extruded polystyrene board, rubber and plastic, polyurethane foam, glass wool, etc.

[0084] In some embodiments, the inner liner 121 side frame is provided with a first side opening 1211A, and the outer shell 122 side frame is provided with a second side opening 1221A. The first side opening 1211A and the second side opening 1221A communicate to form a side opening. The heating box 12 also includes a side cover 123, which is disposed at the side opening and is used to open or close the side opening.

[0085] This allows a through-channel to be formed between the inner liner 121 and the outer shell 122, enabling the inspection and replacement of the electric heating components 15 and radiator 13 inside the heating device 1 by directly opening or closing the side cover 123. In addition, the side cover 123 can also provide heat insulation.

[0086] In some examples, the side cover 123 may be connected to the inner liner 121 and the outer shell 122 by a snap-fit ​​connection.

[0087] In some examples, the side cover 123 can be connected to the inner liner 121 and the outer shell 122 by a sliding rail.

[0088] In some embodiments, the heating device 1 further includes an electric heating component 15, a detection device, and a control unit. The electric heating component 15 is disposed on the wall of the heating box 12. The detection device is used to detect the operating condition of the vehicle 1000. The detection device, the flow regulating device 14, and the electric heating component 15 are all connected to the control unit.

[0089] In this way, by connecting the detection device, the flow regulating device 14 and the electric heating component 15 to the control unit, the control unit can adjust the intake and exhaust volume of the exhaust gas in the exhaust device 2 in real time by adjusting the flow regulating device 14 according to the operating conditions of the vehicle 1000 detected by the detection device, thereby adjusting the heat transferred to the electric heating component 15.

[0090] The heating device 1 has two heat source supply methods: one is to directly supply high-voltage electricity to the power battery and heat the resistance wire through the high-voltage wiring harness; the other is that the exhaust gas from the engine is treated by the exhaust device 2, and then passes through the radiator 13 in the heating device 1 to utilize the residual heat before being discharged.

[0091] Specifically, when the engine is not running, vehicle 1000 is in pure electric mode. The power battery provides high-voltage electricity to directly heat items through the electric heating component 15, and the heating demand is met by adjusting the current through the power distribution device. When the engine is running, vehicle 1000 is in hybrid mode. The control unit continuously adjusts the engine operating conditions according to the overall vehicle power requirements, and the battery SOC also changes accordingly. The entire heating system 100 needs to respond in real time to the changes in energy supply caused by the switching of power modes (pure electric / hybrid / range-extended). Combining AI intelligent temperature control algorithm prediction system power mode switching to provide the optimal solution, dynamically allocate the heat source ratio, and respond to changes in advance to achieve a hybrid heating strategy of "waste heat as the main source and electric energy as a supplement".

[0092] When the engine is running, the vehicle 1000 is in hybrid mode. The heating system 100 prioritizes the use of the exhaust heat of the engine as the main heat source and transfers the exhaust heat energy to the heating device 1 through the radiator 13, thereby reducing the consumption of the power battery. In pure electric mode, it seamlessly switches to the electric heating component 15 for heating, ensuring functional continuity and realizing the gradient utilization of energy.

[0093] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0094] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
