Clean energy refers to energy that does not produce pollutants and can be directly used for production and daily life, including solar, wind, hydro, and biomass energy. With the increasing environmental awareness of society, heating and thermal power equipment is gradually adopting clean energy to replace traditional energy sources.

[0003] CN 217274803 U discloses an integrated clean heating device, which includes a water storage tank and a main unit. Through the cooperation of the water storage tank, electric heater, inlet pipe, outlet pipe, supply pipe, water pump, and return pipe, it meets the basic requirements for heating water. However, the electric heater is the heating source, consuming a large amount of electricity, and the heat storage capacity of the water storage tank needs improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a clean heating equipment with a reasonable structure, reliable use, and high-efficiency energy storage function, which solves the problems of high power consumption and insufficient heat storage function of existing integrated clean heating equipment, makes full use of solar energy in clean energy, reduces power consumption, and has good energy storage effect.

[0005] The technical solution of this utility model is:

[0006] A clean heating device with high-efficiency energy storage function includes a heating box. The key technical features are: a phase change energy storage tank is built into the upper part of the heating box; the phase change energy storage tank is equipped with a serpentine heat exchange pipeline; the inlet end of the serpentine heat exchange pipeline leads out of the top surface of the phase change energy storage tank, and the outlet end leads out of the bottom surface of the phase change energy storage tank and communicates with the lower part of the heating box; the phase change energy storage tank stores phase change material surrounding the serpentine heat exchange pipeline; a heat collection tube bundle is supported on the top of the heating box; the lower end of the heat collection tube bundle communicates with a water distribution chamber, and the upper end of the heat collection tube bundle communicates with a water collection chamber; the outlet of the water collection chamber... The end of the outlet pipe passes through the top surface of the heating box and is fixedly connected to the inlet end of the serpentine heat exchange pipe. A circulation port is provided on one side of the bottom of the heating box. The outer end of the circulation port is connected to a booster pump via a circulation pipe. The end of the outlet pipe of the booster pump is fixedly connected to the inlet of the water distribution chamber. A water replenishment branch is provided on the circulation pipe. A water outlet is provided on the other side of the bottom of the heating box. A photovoltaic module is supported on the top of the water collection chamber. An energy storage component connected to the photovoltaic module is provided on the top surface of the heating box. A heater is provided on the outlet pipe of the water collection chamber. The heater is connected to the energy storage component.

[0007] The aforementioned clean heating equipment with efficient energy storage function comprises a heat collection tube bundle consisting of multiple rows of heat collection tubes, with adjacent rows of heat collection tubes arranged alternately. Each heat collection tube consists of an inner tube, an outer tube, a vacuum layer between the inner and outer tubes, and a thermally conductive coating on the outer surface of the outer tube.

[0008] The aforementioned clean heating equipment with high-efficiency energy storage function has an insulation block layer between the upper and side parts of the phase change energy storage tank and the heating box.

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

[0010] 1. During the day, solar energy is absorbed by the collector tube bundle. Water passing through the collector tube bundle enters the serpentine heat exchange pipeline, and after passing through the serpentine heat exchange pipeline, it is discharged into the lower part of the heating tank. Then, it returns to the collector tube bundle through the circulation port, lift pump, and diversion chamber to continue absorbing heat. During this process, the hot water in the serpentine heat exchange pipeline exchanges heat with the phase change material, which stores thermal energy. Finally, the water temperature entering the lower part of the heating tank rises to the set temperature and can be output for heating. On cloudy days or at night, when the cooler water passes through the serpentine heat exchange pipeline and enters the heating tank, the phase change material exchanges heat with the water, and the water absorbs heat to reach the set temperature, thus meeting the heating demand.

[0011] 2. During the day, the photovoltaic modules convert solar energy into electrical energy and store it in the energy storage modules. When the water temperature is insufficient for heating on cloudy days or at night, the heater connected to the energy storage modules is activated to supply power to the heater. The heater then heats the water flowing through it, providing auxiliary heating.

[0012] In summary, this utility model makes full use of solar energy in clean energy, solves the problems of high power consumption and insufficient heat storage function of existing integrated clean heating equipment, reduces power consumption, and has good energy storage effect.

[0016] The present invention will be described in detail with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, the clean heating equipment with efficient energy storage function includes a heating box 10.

[0018] The upper part of the heating box 10 is equipped with a phase change energy storage tank 11 built in by a connecting rib group.

[0019] The phase change energy storage tank 11 is equipped with a serpentine heat exchange pipeline 9. The inlet end of the serpentine heat exchange pipeline 9 leads out of the top surface of the phase change energy storage tank, and the outlet end leads out of the bottom surface of the phase change energy storage tank and communicates with the lower part of the heating box 10. The phase change energy storage tank 11 stores phase change material 12 that wraps around the serpentine heat exchange pipeline 9. In this embodiment, a heat insulation block layer 6 is provided between the upper part and the side of the phase change energy storage tank 11 and the heating box 10.

[0020] The top of the heating box 10 is supported by a heat collection tube bundle 3. The lower end of the heat collection tube bundle 3 is connected to the water distribution chamber 4, and the upper end of the heat collection tube bundle 3 is connected to the water collection chamber 2. The end of the outlet pipe 16 of the water collection chamber 2 passes through the top surface of the heating box 10 and is connected and fixed to the inlet end of the serpentine heat exchange pipe 9. A circulation port 8 is provided on one side of the bottom of the heating box 10. The outer end of the circulation port 8 is connected to the lift pump 5 via a circulation pipe 13. The end of the outlet pipe of the lift pump 5 is connected and fixed to the inlet of the water distribution chamber 4. A water replenishment branch 7 is provided on the circulation pipe 13. A water outlet 14 is provided on the other side of the bottom of the heating box 10. In this embodiment, the heat collection tube bundle 3 is composed of multiple rows of heat collection tubes, with adjacent rows of heat collection tubes arranged alternately. The heat collection tube is composed of an inner tube, an outer tube, a vacuum layer between the inner and outer tubes, and a thermally conductive coating on the outer surface of the outer tube.

[0021] The top of the water collection chamber 2 is supported by a photovoltaic module 1, and the top surface of the heating box 10 is provided with an energy storage module 17 connected to the photovoltaic module 1. A heater 15 is provided on the outlet pipe of the water collection chamber 2, and the heater 15 is connected to the energy storage module 17.

[0022] Working principle:

[0023] 1. Start the booster pump 5, and send water to the collector tube bundle 3 through the water supply pipe 7. After being heated by the collector tube bundle 3 and the water collection chamber 2, the water enters the serpentine heat exchange pipe 9. During the flow, the heat is transferred to the phase change material for energy storage. The cooled water falls into the lower part of the heating tank 10. After reaching the set water level, the water supply pipe 7 is closed, and the circulation port 8 is opened. The water in the lower part of the heating tank 10 is circulated to the collector tube bundle 3 by the booster pump 5 for reheating, continuously storing energy for the phase change material. After the phase change material has completed energy storage, the temperature of the water in the lower part of the heating tank 10 continuously rises to the set temperature and can be used for heating. When the water in the lower part of the heating tank 10 drops to the set water level, water is sent again through the water supply pipe 7. At this time, the newly entered water can be heated by the collector tube bundle 3, and when it passes through the serpentine heat exchange pipe 9, it exchanges heat with the phase change material. The energy stored in the phase change material is transferred to the water to heat it again, so as to meet the heating demand.

[0024] 2. The photovoltaic module 1 converts solar energy into electrical energy during the day and stores it in the energy storage module 17 for later use.

[0025] 3. When the water temperature does not meet the heating demand on cloudy days or at night, the heater 15 connected to the energy storage component 17 is started to supply power to the heater 15. The heater 15 heats the water flowing through it. The water passing through the heater 15 first stores energy for the phase change material. After the phase change material has finished storing energy, the temperature of the water in the lower part of the heating box 10 continuously rises to the set temperature and can be used for heating.

[0026] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
