Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted equipment, specifically to a heated water storage tank with heat recovery function. Background Technology

[0002] Existing fuel-fired parking heaters often have significant shortcomings in heat source management, 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 heating and storage water tank with heat recovery function that can effectively improve the heat utilization rate of the heat source host, output constant temperature water, has good energy-saving effect, and is safe and reliable.

[0004] To address the above problems, the following technical solution is provided: a heated water storage tank with heat recovery function, comprising a heat source unit and an antifreeze tank, wherein the exhaust pipe of the heat source unit is equipped with an exhaust heat exchanger; the antifreeze tank is equipped with a clean water heat exchanger; and further comprising a first outlet pipe connected to the antifreeze tank and pumping antifreeze through a water pump, wherein the antifreeze, after heat exchange in the exhaust heat exchanger, enters the heat source unit for heat exchange and then enters the clean water heat exchanger before flowing into the inner cavity of the antifreeze tank, or is discharged externally through a second outlet pipe before entering the clean water heat exchanger. The antifreeze tank is also connected to a first inlet pipe for returning antifreeze to the second outlet pipe; and further comprising a second inlet pipe, wherein the downstream of the second inlet pipe is connected to the clean water heat exchanger and then discharges hot water through a third outlet pipe, wherein a fourth outlet pipe is connected before the second inlet pipe enters the clean water heat exchanger, and a thermostatic valve is connected to the third outlet pipe and the fourth outlet pipe, wherein the thermostatic valve is equipped with 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 pump is located on the first outlet pipe upstream of the exhaust heat exchanger.

[0008] 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.

[0009] The beneficial effects of this utility model are:

[0010] 1. When the heat source unit is operating, the antifreeze is drawn by the water pump and sent to the exhaust heat exchanger through the first outlet pipe to exchange heat and increase its temperature. Then, it enters the heat source unit for further heat exchange and increases its temperature before entering the clean water heat exchanger for heat exchange and flowing back to the antifreeze tank. Alternatively, before entering the clean water heat exchanger, it is sent out through the second outlet pipe to meet the heat demand of external heating equipment, and then sent back to the antifreeze tank through the first inlet pipe to achieve antifreeze circulation. The second inlet pipe supplies clean water, which absorbs heat from the antifreeze as it passes through the clean water heat exchanger and is then sent out through the third outlet pipe as hot water. A fourth outlet pipe is connected before the second inlet pipe enters the clean water heat exchanger, and a thermostatic valve is connected between the third and fourth outlet pipes. At this time, the fourth outlet... The first outlet pipe is for cold water, the third outlet pipe is for hot water, and after temperature adjustment by a thermostatic valve, warm water is output through the fifth outlet pipe. Simultaneously, after the machine stops running, the antifreeze can continuously utilize residual heat to exchange heat with the clean water, outputting warm water. The thermostatic valve 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 is added to the exhaust pipe of the heat source unit, improving heat exchange efficiency and ultimately increasing the water temperature by 3-5 degrees Celsius, while reducing exhaust noise and lowering the exhaust temperature from approximately 180 degrees Celsius to approximately 55 degrees Celsius, preventing excessively high exhaust temperatures from causing harm to the human body.

[0011] 2. The heat source unit can also preheat the vehicle engine through antifreeze; the heater can be used to collect heat from the antifreeze, thereby utilizing the vehicle engine or the heat source unit for heating.

[0012] 3. No additional energy source (electric heating) is required to achieve heat storage and output hot water. Attached Figure Description

The exhaust pipe 11 of the heat source unit 10 is equipped with an exhaust heat exchanger 12. The antifreeze tank 20 is equipped with a clean water heat exchanger 21. It also includes a first outlet pipe 23 connected to the antifreeze tank 20 and pumped by a water pump 22 to draw antifreeze. After heat exchange in the exhaust heat exchanger 12, the antifreeze enters the heat source unit 10 for further heat exchange, then enters the clean water heat exchanger 21 before flowing into the inner cavity of the antifreeze tank 20, or enters the clean water... The coolant is discharged through the second outlet pipe 24 before the heat exchanger 21. The antifreeze tank 20 is also connected to the first inlet pipe 25 for returning the antifreeze discharged through the second outlet pipe 24. It also includes a second inlet pipe 26.

The third outlet pipe 27 and the fourth outlet pipe 28 are connected to a thermostatic valve 30. The thermostatic valve 30 is provided with a fifth outlet pipe 31.

[0023] In the above structure, when the heat source unit 10 is in operation, the antifreeze is drawn by the water pump 22 and sent to the exhaust heat exchanger 12 through the first outlet pipe 23 for heat exchange and temperature increase. Then it enters the heat source unit 10 for further heat exchange and temperature increase before entering the clean water heat exchanger 21 for heat exchange and flowing back to the antifreeze tank 20. Alternatively, before entering the clean water heat exchanger 21, it is sent out through the second outlet pipe 24 to meet the heat demand of the external heating equipment, and then sent back to the antifreeze tank 20 through the first inlet pipe 25 to achieve antifreeze circulation.

At the same time, after the machine stops running, the antifreeze can continue to use residual heat to exchange heat with the clean water and output warm water. The thermostatic valve 30 can output hot water at a temperature of 50 degrees Celsius according to the requirements of different countries and regions, which can prevent scalding during use and can always output hot water at the set temperature. An exhaust heat exchanger 12 is added to the exhaust pipe 11 of the heat source host 10 to improve the heat exchange efficiency. The final water temperature can be increased by 3-5 degrees Celsius, and the exhaust noise is reduced. The exhaust temperature of the exhaust pipe 11 is reduced from about 180 degrees Celsius to about 55 degrees Celsius to prevent the exhaust temperature from being too high and causing harm to the human body.

[0029] The above structure facilitates the extraction of antifreeze and the establishment of water pressure upstream of the exhaust heat exchanger 12 and the heat source host 10.

[0030] In this embodiment, a heater 40 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.
