Technical Field
[0001] This utility model relates to the field of vehicle-mounted equipment, specifically to a dual-energy heating and heat storage integrated machine with heat recovery function. Background Technology
[0002] Existing fuel-powered parking heaters often cannot achieve dual-source heating, and their heat source management modes are inadequate, resulting in low thermal efficiency and relatively simple overall functions. Utility Model Content
[0003] Based on the above problems, the purpose of this utility model is to provide a dual-energy heating and thermal storage integrated machine with heat recovery function, which has dual-energy independent or mixed heating, excellent energy-saving effect, and is safe and reliable.
[0004] To address the above problems, the following technical solution is provided: A dual-energy heating and storage integrated machine with heat recovery function, including a heat source unit, an antifreeze tank, and a water tank located inside the antifreeze tank. The water tank is equipped with an electric heater and a clean water heat exchanger. An interlayer for storing antifreeze is formed between the antifreeze tank and the water tank. It also includes a first outlet pipe connected to the interlayer and pumping antifreeze through a water pump. The antifreeze, after heat exchange in the exhaust heat exchanger of the heat source unit, enters the heat source unit for heat exchange again, then enters the clean water heat exchanger and flows back to the interlayer, or is discharged externally through a second outlet pipe before entering the clean water heat exchanger. The interlayer is also connected to a first inlet pipe for returning antifreeze to the second outlet pipe. It also includes a second inlet pipe, downstream of which is connected to the clean water heat exchanger and connected to the water tank, while simultaneously discharging hot water through a third outlet pipe. A fourth outlet pipe is connected before the second inlet pipe enters the clean water heat exchanger. A thermostatic valve is connected to the third and fourth outlet pipes, and the thermostatic valve has a fifth outlet pipe.
[0005] The present invention is further provided that the antifreeze tank is provided with a heat insulation layer.
[0006] The present invention is further configured such that the top of the antifreeze tank is provided with a filling port and a pressure relief port.
[0007] The present invention is further configured such that the water tank is provided with a drain outlet communicating with its bottom; the drain outlet is provided with a manual drain valve / plug or an automatic pressure relief valve or a manual-automatic integrated pressure relief drain valve.
[0008] The present invention is further provided that the water tank is also equipped with a temperature sensor.
[0009] The present invention is further configured such that the water tank is circular, with its two ends convex or flat.
[0010] The present invention is further configured such that the water tank is circular with one end exposed outside the antifreeze tank; a support frame is provided between the bottom of the other end of the water tank and the bottom of the antifreeze tank.
[0011] The present invention is further configured such that the water pump is located on the first outlet pipe upstream of the exhaust heat exchanger.
[0012] The present invention is further configured to include a heater and / or a vehicle engine connected to the downstream of the second outlet pipe and the upstream of the first inlet pipe.
[0013] The beneficial effects of this utility model are:
[0014] 1. Electric heating mode
[0015] The preferred power is 800W. When turned on independently, it can maintain the set water temperature and provide hot water for domestic use and RVs. In winter, when the electric heater is turned on independently, the water pump drives water circulation to prevent freezing.
[0016] In winter when the temperature is low, it can be turned on together with the heat source unit (fuel heater) to quickly raise the water temperature and make up for the insufficient power of the heat source unit (fuel heater);
[0017] It heats the water in the hot water storage tank separately, storing some heat and hot water;
[0018] 2. Fuel heating mode
[0019] In winter when the temperature is low, it can be turned on together with the electric heater to quickly raise the water temperature;
[0020] It can be turned on separately when the temperature is high to provide hot water for domestic use and showering;
[0021] In winter, it can be turned on independently to provide heat to the matching heater through circulating antifreeze, ensuring the temperature of the warm air;
[0022] 3. Hybrid mode
[0023] In winter when the temperature is low, the heat source unit (fuel heater) and the electric heater can be turned on at the same time to quickly increase the water temperature and improve heating efficiency.
[0024] 4. When the antifreeze is connected to the engine coolant (antifreeze) circulation line, the antifreeze is constantly circulating during driving. Through the heat conduction effect of the antifreeze to the water tank in the antifreeze tank, the water in the water tank is always in a heated state, which can provide hot water for domestic or other needs without the use of additional energy.

Detailed Implementation
[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0036] refer to Figures 1 to 9 ,like Figures 1 to 9The illustrated dual-energy heating and storage integrated unit with heat recovery function includes a heat source unit 10, an antifreeze tank 20, and a water tank 30 located within the antifreeze tank 20. The water tank 30 is equipped with an electric heater 31 and a clean water heat exchanger 32. A jacket 21 for storing antifreeze is formed between the antifreeze tank 20 and the water tank 30. The unit also includes a first outlet pipe 23 connected to the jacket 21 and pumped by a water pump 22 to draw antifreeze. The antifreeze undergoes heat exchange through the exhaust heat exchanger 11 of the heat source unit 10, then enters the heat source unit 10 for further heat exchange, and finally enters the clean water heat exchanger 32. The fluid flows back to the jacket 21, or is discharged through the second outlet pipe 24 before entering the clean water heat exchanger 32. The jacket 21 is also connected to a first inlet pipe 25 for discharging antifreeze through the second outlet pipe 24. It also includes a second inlet pipe 33. The second inlet pipe 33 is connected downstream to the clean water heat exchanger 32 and then connected to the water tank 30. At the same time, it discharges hot water through the third outlet pipe 34. The second inlet pipe 33 is connected to a fourth outlet pipe 35 before entering the clean water heat exchanger 32. The third outlet pipe 34 and the fourth outlet pipe 35 are connected to a thermostatic valve 40. The thermostatic valve 40 is provided with a fifth outlet pipe 41.
[0037] In the above structure, antifreeze is stored in the interlayer 21. When the heat source unit 10 is operating, the antifreeze is drawn by the water pump 22 and sent through the first outlet pipe 23 to the exhaust heat exchanger 11 of the heat source unit 10 for heat exchange and temperature increase. It then enters the heat source unit 10 for further heat exchange and temperature increase before entering the clean water heat exchanger 32 to heat the clean water in the water tank 30, and then flows back to the interlayer 21. Alternatively, before entering the clean water heat exchanger 32, it is sent out through the second outlet pipe 24 to meet the heat demand of external heating equipment, and then sent back to the interlayer 21 through the first inlet pipe 25 to achieve antifreeze circulation. The second inlet pipe 33 supplies clean water. After absorbing heat from the antifreeze in the clean water heat exchanger 32, it enters the water tank 30 or is exported as hot water through the third outlet pipe 34. A fourth outlet pipe 35 is connected before the second inlet pipe enters the clean water heat exchanger 32, and a thermostatic valve 40 is connected between the third and fourth outlet pipes 34. In this configuration, the fourth outlet pipe 35 supplies cold water, and the third outlet pipe 34 supplies hot water. After temperature adjustment by the thermostatic valve 40, warm water is output through the fifth outlet pipe 41. The water tank 30 is designed inside the antifreeze tank 20, allowing for the heating of the antifreeze while simultaneously supplying heat to the antifreeze. The internal heat is transferred to the water in the water tank 30. Simultaneously, it enhances the water's insulation after the machine stops operating. Furthermore, after the water in the tank 30 cools down, the heat conduction effect of the outer wall of the tank 30 absorbs the temperature of the antifreeze to maintain the water temperature. The thermostatic valve 40 can output hot water at, for example, 50 degrees Celsius according to the requirements of different countries and regions, preventing scalding during use and ensuring a constant output of the set temperature. An exhaust heat exchanger 11 is added to the exhaust pipe 12 of the heat source unit 10, improving heat exchange efficiency and ultimately increasing the water temperature. The exhaust temperature is reduced by 3-5 degrees Celsius, and exhaust noise is lowered, causing the exhaust temperature of the exhaust pipe 12 to drop from about 180 degrees Celsius to about 55 degrees Celsius, preventing the exhaust temperature from being too high and causing harm to the human body; the water tank 30 can store heat, and when the antifreeze is connected to the antifreeze circulation line of the car engine, it can always store 5L of hot water through heat conduction in the antifreeze while the engine is running, which is beneficial to heat recovery and energy saving; in winter when the temperature is low and the engine is difficult to start, the heat source host 10 and / or the electric heater 31 can be started to preheat the car.
[0038] In this embodiment, the antifreeze tank 20 is provided with a heat insulation layer 50.
[0039] In the above structure, the heat insulation layer 50 can provide insulation for the antifreeze tank 20.
[0040] In this embodiment, the top of the antifreeze tank 20 is provided with a filling port 26 and a pressure relief port 27.
[0041] The above structure is used for adding and depressurizing antifreeze.
[0042] In this embodiment, the water tank 30 is provided with a drain outlet 36 communicating with its bottom; the drain outlet 36 is provided with a manual drain valve / plug or an automatic pressure relief valve or a manual-automatic integrated pressure relief drain valve 60.
[0043] The above structure is used for draining and depressurizing the water tank 30.
[0044] In this embodiment, a temperature sensor 37 is also provided inside the water tank 30.
[0045] In the above structure, the temperature sensor 37 monitors the water temperature in the water tank 30 and works with the electric heater 31 to control the electric heating temperature.
[0046] In this embodiment, the water tank 30 is circular, with both ends convex or flat.
[0047] In the above structure, both ends are preferably convex to effectively ensure the overall pressure-bearing capacity.
[0048] In this embodiment, the water tank 30 is circular with one end exposed outside the antifreeze tank 20; a support frame 70 is provided between the bottom of the other end of the water tank 30 and the bottom of the antifreeze tank 20.
[0049] In the above structure, one end of the water tank 30 is exposed outside the antifreeze tank 20 for easy connection; the support frame 70 is used to assist in supporting the water tank 30.
[0050] In this embodiment, the water pump 22 is located on the first outlet pipe 23 upstream of the exhaust heat exchanger 11.
[0051] The above structure facilitates the extraction of antifreeze and the establishment of water pressure upstream of the exhaust heat exchanger 11 and the heat source host 10.
[0052] In this embodiment, a heater 80 and / or a vehicle engine (not shown in the figure) connected to the downstream of the second outlet pipe 24 and the upstream of the first inlet pipe 25 are also included.
[0053] In the above structure, the heat source host 10 can also preheat the vehicle engine through antifreeze; the heater 80 can be used to collect heat from the antifreeze, thereby utilizing the vehicle engine or the heat source host for heat collection.
[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
