Detailed Implementation

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figure 1 As shown, the vehicle heating system of this embodiment includes an engine 1, a circulation pipe 2, a heater 3, and a first heat exchanger 4.

[0042] The circulation pipe 2 can be a ring structure, allowing the antifreeze and other liquids from engine 1 to circulate along the circulation pipe 2, thus meeting the need for circulating delivery of antifreeze and other liquids. Engine 1 is located in the circulation pipe 2; for example, engine 1 can be connected in series with the circulation pipe 2. During use, antifreeze can be circulated along the circulation pipe 2 to engine 1.

[0043] The heater 3 is used to burn and heat the gas, and the heater 3 has a first outlet 31 for supplying warm air to achieve heating inside the vehicle and a second outlet 32 ​​for supplying exhaust gas generated by combustion.

[0044] For example, heater 3 can be a heating device with an independent combustion system, fuel supply system, and combustion air intake system. Heater 3 has two independent outlets, namely the first outlet 31 and the second outlet 32 ​​mentioned above. In use, the warm air generated by heater 3 can be discharged into the vehicle through the first outlet 31, thereby achieving heating of the vehicle interior. The exhaust gas generated during the heating process can be discharged through the second outlet 32.

[0045] The first heat exchanger 4 is located in the circulation pipeline 2 and connected to the second outlet 32. The first heat exchanger 4 is used to heat the antifreeze through the exhaust gas, and the heated antifreeze is used to heat the engine 1.

[0046] For example, the first heat exchanger 4 can be a gas-liquid heat exchanger. Specifically, the first heat exchanger 4 can include a housing and a pipeline disposed within the housing. The high-temperature exhaust gas discharged through the second outlet 32 ​​can be discharged into the housing, while the pipeline within the housing can be connected to the circulation pipeline 2 and used to supply antifreeze.

[0047] During use, the high-temperature exhaust gas flowing into the casing can exchange heat with the antifreeze in the pipeline, thereby heating the antifreeze and utilizing the heat of the exhaust gas, thus improving the overall heat utilization rate. The heated antifreeze can then be transported to the engine 1 through the circulation pipeline 2 to heat and preheat the engine 1.

[0048] In the vehicle heating system of this embodiment, the heater 3 can independently supply warm air to the vehicle interior during use, thereby meeting the user's heating needs. Secondly, the exhaust gas generated can heat the antifreeze, thereby preheating the engine 1 and avoiding the situation where the engine 1 cannot start or is easily damaged during cold starts in extremely cold weather such as winter.

[0049] In addition, since the combustion of heater 3 is more complete and efficient than that of engine 1, and the overall fuel consumption is lower, the overall heating economy and environmental protection are improved, and the pollution of the exhaust gas produced by the heater is reduced, thus achieving the effect of energy saving and environmental protection.

[0050] In some embodiments, such as Figure 1 As shown, the vehicle heating system includes a heating assembly 5, which includes a housing 51 and a second heat exchanger 52.

[0051] The housing 51 is provided with multiple warm air outlets 511, and the first outlet 31 is connected to the housing 51 so that the warm air generated by the heater 3 can be discharged through the warm air outlet 511. For example, Figure 1 As shown, the housing 51 can be roughly box-shaped. The first outlet 31 can be connected to the bottom of the housing 51 through a pipe, and multiple warm air outlets 511 can be provided on the top side of the housing 51.

[0052] In use, the warm air discharged through the first outlet 31 can be first delivered into the housing 51, and then discharged through multiple warm air outlets 511 on the housing 51. The housing 51 can buffer the flow of warm air, so that the warm air can be discharged into the car more gently, which is conducive to improving the user experience.

[0053] It should be noted that the number of warm air outlets 511 can be set to 2, 3, 4, 5, 6, etc. The number of warm air outlets 511 can be selectively set according to the actual layout needs of the vehicle and the type of vehicle. Furthermore, the warm air outlets 511 can be connected to the housing 51 through hoses or other pipes, so as to facilitate the delivery of the warm air outlets 511 to the seats, the central control unit, the floor, and other locations.

[0054] The second heat exchanger 52 is located in the circulation pipeline 2 and inside the housing 51. When the engine 1 is running, the second heat exchanger 52 is used to heat the gas discharged through the heater outlet 511 by the antifreeze to achieve heating in the vehicle.

[0055] For example, such as Figure 1 As shown, the second heat exchanger 52 can be connected in series with the aforementioned circulation pipe 2, and the second heat exchanger 52 as a whole can be located inside the aforementioned housing 51. When the engine 1 is started and running, liquids such as antifreeze can be transported to the second heat exchanger 52 through the circulation pipe 2, thereby heating the gas inside the housing 51. The heated gas inside the housing 51 can then be discharged through the aforementioned warm air outlet 511, thus enabling the supply of warm air through the operation of the engine 1.

[0056] It should be noted that the aforementioned housing 51 may be provided with a dedicated air inlet, so that when the second heat exchanger 52 heats the gas inside the housing 51, the gas inside the housing 51 can be replenished through the air inlet.

[0057] In some embodiments, such as Figure 1 As shown, the vehicle heating system includes a first connecting pipe 6, one end of which is sealed and connected to a first outlet 31, and the other end of which is connected to the housing 51 via a pipe fitting. This facilitates the sealed connection between the first outlet 31 and the housing 51, thereby meeting the need for delivering warm air into the housing 51.

[0058] In some embodiments, the first connecting tube 6 is a flexible tube. For example, the material of the first connecting tube 6 can be plastic, stainless steel braided tubing, etc., so that the overall shape of the first connecting tube 6 can be adjusted according to actual needs, which facilitates its use.

[0059] In some embodiments, the heating assembly 5 includes a fan 53 for delivering gas from the housing 51 to a plurality of heating outlets 511, and the fan 53 stops operating when the heater 3 is running and operates when the engine 1 is running.

[0060] For example, such as Figure 1 As shown, the fan 53 can be located on the top side of the second heat exchanger 52. When heating is provided by the heater 3, the fan 53 can be turned off, so that the heating needs can be met by the fan attached to the heater 3 itself, thus reducing energy consumption. When heating is provided by the engine 1, the fan 53 can be started. At this time, the warm air heated by the second heat exchanger 52 can be delivered to the warm air outlet 511 by the fan 53, thus meeting the need for supplying warm air.

[0061] In some embodiments, such as Figure 1 As shown, the heater 3 is provided with a first inlet 33, a second inlet 34 and a third inlet 35. The first inlet 33 is used to introduce fuel into the heater 3, and the second inlet 34 is used to introduce combustion-supporting gas into the heater 3. The fuel and the combustion-supporting gas can be introduced into the heater 3 at the same time and can be burned in the heater 3, thereby meeting the heating needs.

[0062] Secondly, the heater 3 is equipped with a heating tube, which connects the third inlet 35 and the first outlet 31. The heating tube is used to heat the gas flowing in through the third inlet 35 during the combustion of fuel and combustion-supporting gas. This achieves isolation of the delivery of warm air and ensures the quality of the supplied warm air.

[0063] In some embodiments, such as Figure 1As shown, the vehicle heating system includes a second connecting pipe 7, one end of which is connected to a second outlet 32, and the other end of which is connected to a first heat exchanger 4. The second connecting pipe 7 can also be a flexible hose, thus meeting the need to supply the exhaust gas generated by the heater 3 to the first heat exchanger 4.

[0064] In some embodiments, the first heat exchanger 4 is provided with an exhaust port 41 for discharging exhaust gas after heat exchange with the antifreeze. For example, as Figure 1 As shown, the exhaust port 41 can be located on the top side of the first heat exchanger 4. The exhaust gas after heat exchange in the first heat exchanger 4 can be directly discharged through the exhaust port 41, thereby meeting the usage requirements for exhaust gas discharge.

[0065] In some embodiments, such as Figure 1 As shown, the vehicle heating system also includes an expansion tank 8, a pump body 9, and a radiator 10.

[0066] An expansion tank 8 is located in the circulation line 2 and is used to store antifreeze. The expansion tank 8 is also used to replenish antifreeze into the circulation line 2. For example, as... Figure 1 As shown, the expansion tank 8 can be an expansion water tank. The expansion tank 8 can be located upstream of the first heat exchanger 4. During use, the antifreeze in the circulation pipe 2 may evaporate. The expansion tank 8 can be used to replenish the antifreeze in the circulation pipe 2 in a timely manner.

[0067] Pump body 9 is located in circulation pipe 2 and is used to drive the antifreeze in circulation pipe 2 to circulate. For example, Figure 1 As shown, the pump body 9 can be a circulating water pump. Specifically, the pump body 9 can be connected downstream of the first heat exchanger 4. In use, the pump body 9 can be used to circulate and pump the antifreeze in the circulating pipeline 2.

[0068] The radiator 10 is located in the circulation pipe 2 and is used to enhance the heat dissipation efficiency of the engine 1. This reduces the operating temperature of the engine 1.

[0069] The following describes the usage method of embodiments of the present invention.

[0070] The usage method of this invention has a parking mode and a driving mode.

[0071] In parking mode, engine 1 is off, and only heater 3 is activated to provide heating to the vehicle interior. This satisfies the need for continuous heating, and the high efficiency of heater 3's combustion contributes to energy conservation and environmental protection, reducing fuel consumption and improving fuel economy. Furthermore, it avoids the problems of prolonged idling of engine 1 during parking, which can lead to carbon monoxide buildup and other issues, thus enhancing safety and reducing the risk of injury.

[0072] In driving mode, engine 1 is started and the heat generated by engine 1 is used to heat the vehicle interior, while heater 3 is turned off. Thus, heating can be achieved simultaneously through engine 1, while turning off heater 3 helps reduce overall energy consumption, further improving the economy of use and the efficient use of energy.

[0073] In some embodiments, the method of use includes the following steps:

[0074] The heater 3 is activated, and the hot air generated by the heater 3 provides heating to the vehicle interior. The exhaust gas generated by the heater 3 also heats the antifreeze flowing to the engine 1. Specifically, after the heater 3 is activated, the hot air generated by the heater 3 can be supplied to the vehicle interior through the first outlet 31, thereby meeting the need for supplying warm air for heating. The exhaust gas generated by combustion in the heater 3 can be discharged through the second outlet 32, thereby heating the antifreeze with the high temperature of the exhaust gas. In turn, the antifreeze can preheat the engine 1, preventing the engine 1 from failing to start or from having a cold start.

[0075] After the antifreeze has heated the engine 1 for a set time, start the engine 1 and turn off the heater 3. Specifically, the set time can be the length of time required to heat the engine body and engine oil of the engine 1 to the temperature at which the engine 1 can be started. Once the starting temperature of the engine 1 meets the requirements, the engine 1 can be started directly, and the heater 3 can be turned off at the same time.

[0076] It should be noted that in some other embodiments, the heater 3 can also operate simultaneously with the engine 1, thereby increasing the overall heating intensity and meeting the needs for rapid heating and improved heating effect.

[0077] The heat generated by engine 1 is used to heat the vehicle interior. Specifically, the antifreeze heated by engine 1 can be transported to the second heat exchanger 52 via circulation pipe 2. The second heat exchanger 52 can heat the gas, and the heated gas can be discharged into the vehicle interior through the heater vent 511, thereby also heating the vehicle interior.
