[0002] A parking heater is an onboard heating device that operates independently of the vehicle's engine. It can preheat the engine and cab without starting the engine, making it particularly suitable for low-temperature winter conditions. It primarily heats the interior of the vehicle and the engine by burning fuel to heat the coolant in the radiator.

[0003] Current heaters commonly include air heaters, specifically an air heater disclosed in Chinese Patent Publication No. "CN208458260U", and water heaters, specifically a parking heater disclosed in Chinese Patent Publication No. "CN109736992A".

[0004] In terms of water heating function, the heating efficiency of water heaters is better than that of air heaters. However, when used outdoors, a single water heater structure is currently unable to support the expansion of heating components in multiple tents. Considering the recycling of the high-temperature exhaust gas of the water heater to further optimize the heating effect of water, we propose a heating system that supports multi-unit expansion. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the existing technology that a single water heater structure cannot support the expansion of heating elements in multiple tents, and to propose a heating system that supports multi-unit expansion.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Design a heating system that supports multi-unit expansion, including:

[0008] a heating unit and at least one heat receiving unit;

[0009] The heating unit at least includes a heating body, a negative pressure water channel and an output water channel, wherein the heating body is used to heat the fluid in the output water channel, and the negative pressure water channel and the output water channel constitute a circulating water channel;

[0010] At least one of the heat receiving units is connected to the negative pressure water circuit and the output water circuit to obtain heat from the circulating water circuit.

[0011] Furthermore, the heating body is a water heater and a heat exchanger, and the input end of the heat exchanger is connected to the exhaust gas output end of the water heater.

[0012] Furthermore, it also includes an oil tank, which supplies oil to the water heater through an oil pump, and a tank cap is detachably connected to the oil tank.

[0013] Furthermore, the negative pressure water circuit includes a water tank, and a water tank cover is detachably connected to the top of the water tank, wherein a return water pipe is connected between the water tank and the heating unit.

[0014] Furthermore, the output water circuit includes a water pump connected to the water tank pipeline, the output end of the water pump is connected to the input end of the heat exchanger, and a water outlet pipe is provided on the output end of the heat exchanger.

[0015] Furthermore, the heating unit further includes a first shell, and the heating body, the negative pressure water channel and the output water channel are all installed in the first shell.

[0016] Furthermore, the heating unit is a hydrothermal blanket and / or a hydrothermal air conditioner and / or a water storage device and / or a window heat exchange device.

[0017] Furthermore, the hydrothermal air conditioner includes a second shell, a heat exchange element and a fan disposed in the second shell, and the input and output ends of the heat exchange element are connected to the negative pressure water channel and the output water channel respectively.

[0018] Furthermore, the heat exchange element includes two opposite hollow tubes, one of the hollow tubes is further provided with a partition for separating the input and output ends, and a side cover connected between the two hollow tubes;

[0021] The utility model proposes a heating system that supports multi-unit expansion, which has the following beneficial effects: compared with an air heater, the heating system of the utility model has a greater heat energy loss in the process of converting air heating into water heating. The water heater itself is a water heating boiler. The internal combustion chamber burns diesel to directly heat the circulating water in the boiler, thereby reducing heat loss. With the help of the exhaust gas emissions of the water heater, the heat exchanger can preheat the water, which not only improves energy utilization, but also achieves a better water heating effect.

[0022] Secondly, since the water is preheated and then heated in a cycle, it is more efficient in realizing a hydrothermal air-conditioning heating system. The main unit of the air heater can only achieve a heating effect of one to two at most, while the main unit of the water heater can achieve a heating effect of one to three, one to four, or even one to five. This means that a water heater can heat multiple tents at the same time, thereby greatly improving its applicability and scalability for outdoor use. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-6This is an embodiment of the present invention, which discloses a heating system that supports multi-unit expansion. The heating system is mainly used to solve the problem that traditional heaters cannot support multi-unit expansion outdoors, so that when used outdoors, it can support heating multiple tents and achieve better applicability. Specifically, the heating system includes a heating unit 1 and at least one heat receiving unit 2;

[0032] The heating unit 1 at least includes a heating body 11, a negative pressure water channel 12 and an output water channel 13, wherein the heating body 11 is used to heat the fluid in the output water channel 13, and the negative pressure water channel 12 and the output water channel 13 constitute a circulating water channel;

[0033] At least one of the heat receiving units 2 is connected to the negative pressure water circuit 12 and the output water circuit 13 to obtain heat from the circulating water circuit.

[0034] In some embodiments, the heating body 11 is a water-heating heater 111 and a heat exchanger 112. The input end of the heat exchanger 112 is connected to the exhaust gas output end of the water-heating heater 111. The heat exchanger 112 described in this embodiment is a prior art and will not be described in detail here. For details, you can also refer to the structural description of the heat exchanger 222 in this solution. The two have the same principles. Secondly, in this embodiment, the high-temperature exhaust gas generated by the water-heating heater 111 is used to heat the water flow, which can realize the recycling of the exhaust gas and achieve the purpose of energy saving and environmental protection. In addition, a muffler 15 can be installed at the exhaust outlet of the heat exchanger 112 to reduce emission noise.

[0035] Reference Figure 3 、 4 Furthermore, the heating body 11 described in this embodiment also includes a fuel tank 113, and the fuel tank 113 supplies oil to the water heater 111 through an oil pump 114. The fuel tank 113 is detachably connected to a fuel tank cover 115. Preferably, the fuel tank cover 115 is connected to the fuel tank 113 in a threaded manner. Secondly, in this embodiment, the fuel tank 113 is welded in one piece of all-metal. The fuel tank 113 is provided with an oil-resistant two-way air valve, which can only allow air to pass through but not diesel. In this way, even if the fuel tank is tilted or even inverted, there will be no oil leakage, and there will be no oil leakage and no diesel smell.

[0036] Reference Figure 3 On the basis of the above embodiment, the negative pressure water circuit 12 in this embodiment includes a water tank 121. Preferably, the water tank 121 in this embodiment is welded in one piece of all-metal, and a water tank cover 122 is detachably connected to the top of the water tank 121. Of course, the water tank cover 122 in this embodiment can also be connected to the water tank 121 in a threaded connection manner, wherein a return water pipe 123 is connected between the water tank 121 and the heating unit 2.

[0037] On top of the water tank 121 is a one-way exhaust valve, the purpose of which is to enable the gas in the water tank 121 to be discharged outward in one direction without entering the water tank 121. In addition, as mentioned above, when the water tank cover 122 is closed tightly, the entire water circuit circulates, and the negative pressure generated in the water tank 121 is used to absorb water, realizing water-electricity separation, and can achieve continuous heating of the water in the water tank 121 after the water circuit circulates;

[0038] In addition, the one-way exhaust valve may not be provided, and the sealing or opening state of the entire water tank 121 can be adjusted by tightening or opening the water tank cover 122 to meet the negative pressure working requirements.

[0039] That is, the water heater 111 in the present utility model is a powerful device with the following features:

[0040] High-temperature hot water function: The water temperature of the water heater can be set to a maximum of 90 degrees, which can achieve high-temperature hot water disinfection and is suitable for various scenarios such as blanching vegetables, shaving poultry and livestock, etc.

[0041] A great tool for outdoor cooking: In outdoor environments, the water heater can cook eggs, corn, ham, canned eight-treasure porridge, coconut milk, milk and other foods. It can even heat tofu sealed in plastic bags, bottled and canned foods, giving you the fun experience of cooking food in an artificial hot spring in the wild.

[0042] Negative pressure self-priming water external circulation: No need to turn on the machine, just use the negative pressure self-priming water function of the water pump, place the inlet and outlet pipes in mountain spring water, stream or a bucket of tap water, and you can achieve the effect of water-cooled air conditioning and water-cooled blanket.

[0043] Multifunctional outdoor bathing system: The water heating circulation system of the water heater can meet the needs of outdoor showering, bathing, sweat steaming, sauna, etc. It can also heat the water for outdoor ton-level swimming pools to create outdoor artificial hot springs.

[0044] Safe and energy-saving: The water heater is ultra-quiet, and has the advantages of free hot water and energy saving.

[0045] Wide range of applications: The water heater can meet the heating and hot water needs of large-scale outdoor camping such as team building, fully demonstrating its powerful water-heat circulation system function.

[0046] Reference Figure 3 、 4In some embodiments, the output water path 13 includes a water pump 131 connected to the water tank 121 pipeline, the output end of the water pump 131 is connected to the input end of the heat exchanger 112, and the output end of the heat exchanger 112 is provided with a water outlet pipe 132. The specific heating principle is that when the water heater 111 is working, the high-temperature exhaust gas it generates enters the heat exchanger 112, and the water pump 131 pumps the water in the water tank 121 into the heat exchanger 112 for heat exchange. The heated water will be heated again through the water heater 111. Since a secondary heating operation is adopted, a higher water temperature can be obtained. The water after secondary heating flows outward from the outlet pipe 132 connected to the water heater 111 into the heating unit 2. After the heat is dissipated in the heating unit, the water flow returns to the water tank 121 through the return pipe 123, thereby realizing a circulating heating function.

[0047] Taking into account the overall convenient mobility, the heating unit 1 in this embodiment also includes a first shell 14, and the heating body 11, the negative pressure water channel 12 and the output water channel 13 are all installed in the first shell 14. A number of holes are opened in the first shell 14 to meet the air intake needs of the heating body 11. For example, the water heater 111 needs to be connected to a combustion intake pipe when working, and the combustion intake pipe can be placed in the hole.

[0048] Reference Figure 1 Specifically, the heating unit 2 in this embodiment is a hydrothermal blanket 21 and / or a hydrothermal air conditioner 22 and / or a water storage device 23 and / or a window heat exchange device 24. The specific layout can be adaptively selected according to actual needs, such as selecting a single hydrothermal blanket 21, hydrothermal air conditioner 22 or water storage device 23, or selecting multiple of them to work simultaneously. Since the internal combustion chamber of the hydrothermal heater 111 burns diesel and directly heats the circulating water in the boiler, its heat loss is extremely low. Therefore, with its powerful water heating capacity, it can support the use of multiple heating units 2. The specific window heat exchange device 24 includes a mounting plate and a heat exchanger. The heat exchanger is connected to the circulating water circuit to achieve heat exchange. The mounting plate is clamped on the car window to achieve heating in the car. The heater structure can refer to the structural principle of the hydrothermal air conditioner 22 described below, which will not be elaborated here.

[0049] In a specific application scenario, such as when using a tent in a low-temperature outdoor environment, the above-mentioned hydrothermal blanket 21 and hydrothermal air conditioner 22 can be placed in the tent and heated by the hydrothermal heater 111 to provide the temperature inside the tent. At the same time, due to the powerful hydrothermal capacity of the hydrothermal heater 111, it can support the simultaneous use of multiple tents to optimize the applicability of outdoor use.

[0050] Secondly, the water storage device 23 described in this embodiment can be set as a swimming pool or a water tank. With the help of the design of the negative pressure water circuit 12, since the interior of the water tank 121 is a sealed space, when the water pump 131 pumps water outward, the negative pressure in the water tank 121 forces the water source in the water storage device 23 to flow back into the water tank 121, and then is heated by the water pump 131, thereby achieving the purpose of reciprocating circulation heating. Taking the pool as an example, in this embodiment, the ends of the return pipe 123 and the outlet pipe 132 are placed in the pool to achieve reciprocating heating of the water in the pool, so as to achieve the purpose of outdoor hot water bathing.

[0051] Reference Figure 5 、 6 In some embodiments, the hydrothermal air conditioner 22 in the present invention includes a second shell 221 and a heat exchanger 222 and a fan 223 placed in the second shell 221. The input and output ends of the heat exchanger 222 are respectively connected to the negative pressure water channel 12 and the output water channel 13.

[0052] The heat exchange element 222 includes two opposing hollow tubes 2221. Specifically, both ends of the hollow tubes 2221 are sealed. A partition 2225 is provided inside one of the hollow tubes 2221 for separating the input and output ends. The input and output ends include an input interface and an output interface, which can be formed by water pipe joints, and a side cover 2222 connected between the two hollow tubes 2221.

[0053] A plurality of fins 2223 are fixedly mounted between the two hollow tubes 2221. Specifically, in this embodiment, the two hollow tubes 2221 and the two fins 2223 together form a frame structure, and the input and output ends are connected to the negative pressure waterway 12 and the output waterway 13 respectively to realize water supply, so as to perform heat exchange through the fins 2223.

[0054] Reference Figure 6 In order to further optimize the heat exchange effect, in this embodiment, a heat pipe 2224 is fixedly installed between adjacent fins 2223. The two ends of the heat pipe 2224 extend to the interior of the two hollow tubes 2221 respectively. That is, the heat pipe 2224 is designed to connect the two hollow tubes 2221 so that the heated water can flow along the heat pipe 2224 to achieve optimal contact and heat conduction with the fins 2223. The fan 223 then blows out the heat to heat the interior of the tent.

[0055] In summary, the heating system of the present invention has a greater heat energy loss in the process of converting air heating into water heating than the air heater. The water heater itself is a water heating boiler. The internal combustion chamber burns diesel to directly heat the circulating water in the boiler, thereby reducing heat loss. Secondly, the water heater is more efficient in realizing the water-heating air conditioning heating system. The air heater host can only achieve a heating effect of one-to-two at most, while the water heater host can achieve a heating effect of one-to-three, one-to-four, or even one-to-five. This means that a water heater can heat multiple tents at the same time, which greatly improves the applicability and scalability for outdoor use.

[0056] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
