Description

Technical Field

[0001] This invention relates to the field of water heater technology, and in particular to a multifunctional solar heating machine heat storage chamber. Background Technology

[0002] A solar heating system is a device that absorbs solar radiation energy through collectors and converts it into heat energy, then uses circulating pipes to transport the heat to a hot water tank for storage, and finally supplies heating and domestic hot water to the end users.

[0003] Existing solar heating systems are often assembled from dispersed components such as collectors, water tanks, circulating pumps, and heat exchangers. The piping is complex, heat loss is high, and space is occupied. In addition, the water tanks used in general solar heating systems have a single function. When heating and hot water circulation share the same water tank, they are prone to crosstalk, making it difficult to achieve stable pressurized operation and independent temperature control.

[0004] Therefore, there is an urgent need for a solar thermal generator heat storage chamber that can achieve multiple functions. Summary of the Invention

A heat collection system is formed by a heat collection circulation pump, a heat collection inlet pipe, and a heat collection return pipe. Hot water heated by solar energy is collected in the water tank and driven by a heating circulation pump in the heating system. The circulating water flows through the heating outlet heat exchange pipe and the heating inlet heat exchange pipe, and is heated through the heating outlet on the heating return valve. The returned water, after releasing heat, enters the circulation system from the heating return port. A water replenishment valve in the clean hot water system controls cold water to enter the hot water inlet heat exchange pipe and the hot water outlet heat exchange pipe through the cold water inlet pipe, where it is heated. Finally, clean hot water is supplied to the user through the hot water outlet on the hot water return valve. This invention integrates four independent systems—solar heat collection, heat storage, heating, and hot water—into a single, highly efficient energy storage chamber. Each circulation system operates independently, resulting in energy savings, cost reduction, and convenient installation and maintenance.

[0006] To achieve the above objectives, the present invention provides a multifunctional solar thermal generator heat storage chamber, comprising a water tank body, with a first insulation chamber and a second insulation chamber respectively provided at the front and rear ends of the water tank body. The first insulation chamber is equipped with a heating circulation pump and a water supply valve.

The water tank body is equipped with a hot water inlet heat exchange pipe, a hot water outlet heat exchange pipe, a heating inlet heat exchange pipe, and a heating outlet heat exchange pipe.

[0007] Preferably, the water tank body includes an inner tank liner, a water tank insulation layer, and an outer tank shell.

[0008] Preferably, the water tank body consists of, from the inside out, the inner tank liner, the water tank insulation layer, and the water tank outer shell, with a communication cable conduit installed in the water tank insulation layer.

[0015] Preferably, the heating inlet heat exchange pipe is connected to the heating connection pipe and the heating return pipe at both ends, and the heating outlet heat exchange pipe is connected to the overflow vent and the heating circulation pump at both ends.

[0016] Therefore, this invention employs a multifunctional solar thermal generator heat storage chamber, which achieves heat storage through the water tank itself.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1 This invention provides a multifunctional solar heating machine heat storage chamber, such as... Figure 3 As shown, it includes the water tank body 1, such as Figure 4 As shown, the water tank body 1 consists of, from the inside out, an inner tank 5, a water tank insulation layer 6, and a water tank outer shell 7. The inner tank 5 is in direct contact with the stored hot water, withstands water pressure, and prevents leakage. The water tank insulation layer 6 is made of insulation material and is used to reduce heat loss from the inside of the water tank. The water tank outer shell 7 is used to form an overall structural support and protection to prevent damage from external forces.

[0023] A communication cable conduit 8 is installed in the water tank insulation layer 6. The communication cable conduit 8 is used to connect the electrical components in the water tank body 1 to achieve unified control and management. The water tank body 1 has a first insulation cavity 12 and a second insulation cavity 4 at the front and rear ends, respectively. Both the first insulation cavity 12 and the second insulation cavity 4 are equipped with insulation covers 2 on the outside. An outer barrel end cover 3 is installed on the outside of the insulation cover 2. The insulation cover 2 is used to reduce heat loss and maintain the temperature inside the cavity. The outer barrel end cover 3 is used to protect the internal structure.

[0024] The inner tank liner 5, the insulation layer 6, and the outer shell 7 of the water tank body 1, together with the first insulation cavity 12 and the second insulation cavity 4 on both sides, as well as the outer insulation cover 2 and the outer barrel end cover 3, together form a heat storage system to store the heat transferred by the heat collection system and provide a stable heat source for the heat exchange tubes of the heating system and the hot water system.

[0025] like Figure 2 As shown, the second insulation cavity 4 is also equipped with a heat collection circulation pump 24 and a heat collection return water pipe 23. The heat collection circulation pump 24 is connected to a heat collection inlet water pipe 25, which is connected to the inside of the water tank body 1. The heat collection return water pipe 23 is connected to the inside of the water tank body 1. The heat collection circulation pump 24 and the heat collection return water pipe 23 are connected to an external solar collector. The heat collection circulation pump 24, the heat collection inlet water pipe 25, and the heat collection return water pipe 23 constitute a heat collection system. The rear end of the heat collection return water pipe 23 is connected to a guide pipe 31.

[0026] The solar collector circulation pump 24 drives the water at the bottom of the water tank body 1 to flow to the external solar collector through the solar collector inlet pipe 25. After the water absorbs solar energy and heats up in the collector, it returns to the inside of the water tank body 1 through the solar collector return pipe 23. The guide pipe 31 is used to send the high-temperature return water into the depth of the water tank body 1 to avoid the problem of water mixing caused by the distance being too close to the solar collector inlet pipe 25, thus completing the circulation and continuously transporting and storing solar thermal energy in the water tank body 1.

[0027] The water tank body 1 is equipped with a hot water inlet heat exchange pipe 26, a hot water outlet heat exchange pipe 27, a heating inlet heat exchange pipe 28, and a heating outlet heat exchange pipe 9. The second insulation cavity 4 is equipped with a heating connection pipe 10 and a hot water connection pipe 22. One end of the heating connection pipe 10 is equipped with an overflow prevention vent 21.

[0028] like Figure 1 As shown, a heating circulation pump 20 and a water supply drive valve 18 are installed in the first insulation cavity 12. The heating circulation pump 20 is connected to a heating return water valve 13, which is connected to a heating return water pipe 14. The water supply drive valve 18 is connected to a cold water inlet pipe 17, which is connected to a hot water return water valve 15. The heating return water valve 13 is provided with a heating outlet 19, the hot water return water valve 15 is provided with a hot water outlet 16, the heating return water pipe 14 is provided with a heating return water inlet, and the cold water inlet pipe 17 is provided with a cold water inlet.

[0029] The hot water inlet heat exchange pipe 26 is connected to a water supply drive valve 18 and a hot water connection pipe 22 at both ends, and the hot water outlet heat exchange pipe 27 is connected to a hot water connection pipe 22 and a hot water return valve 15 at both ends, respectively. The heating inlet heat exchange pipe 28 is connected to a heating connection pipe 10 and a heating return pipe 14 at both ends, and the heating outlet heat exchange pipe 9 is connected to an overflow vent 21 and a heating circulation pump 20 at both ends, respectively.

[0030] The heating system consists of a heating circulation pump 20, a heating return water valve 13, a heating return water pipe 14, a heating inlet heat exchange pipe 28, a heating connection pipe 10, an overflow prevention vent 21, and a heating outlet heat exchange pipe 9.

[0031] Low-temperature cold water from the external heating pipes enters the heating system through the heating return inlet, flows along the heating return pipe 14 into the heating inlet heat exchange pipe 28, where it undergoes initial heating through heat exchange. The pre-heated hot water flows out of the heat exchange pipe and into the heating connection pipe 10, passing through the overflow vent 21 to release any gas in the pipe. It then enters the heating outlet heat exchange pipe 9, where it absorbs heat from the water tank a second time, becoming high-temperature hot water. The heating circulation pump 20 draws this high-temperature hot water from the heating outlet heat exchange pipe 9 and pushes it towards the heating return valve 13. The heating return valve 13 bypasses a portion of the high-temperature hot water, mixing it proportionally with the newly entered low-temperature cold water from the heating return inlet. The resulting hot water, reaching the preset temperature, is then output from the heating outlet 19 to the external heating pipes.

[0032] The hot water system consists of a water supply drive valve 18, a cold water inlet pipe 17, a hot water inlet heat exchange pipe 26, a hot water connection pipe 22, a hot water outlet heat exchange pipe 27, and a hot water return valve 15.

[0033] Cold water from outside enters the cold water inlet pipe 17 through the cold water inlet and then splits into two streams. One stream, controlled by the water supply valve 18, first flows into the hot water inlet heat exchange pipe 26 to absorb heat from the hot water in the tank for preheating. Then, it passes through the hot water connection pipe 22 into the hot water outlet heat exchange pipe 27 for secondary heating, becoming high-temperature clean hot water, which is then sent to the hot water return valve 15. The other stream of cold water, without heating, flows directly through the cold water inlet pipe 17 into the hot water return valve 15. The hot water return valve 15 mixes the high-temperature hot water and cold water in a specific ratio, thereby precisely controlling the temperature of the hot water flowing out of the hot water outlet 16, providing users with domestic hot water at a certain temperature. The clean water flowing throughout the heat exchange pipes is completely isolated from the heat medium in the tank, achieving pressurized operation and ensuring clean and hygienic water use.

[0034] The first heat preservation cavity 12 is also provided with an exhaust port 11 that connects to the inside of the water tank body 1. The exhaust port 11 is used to discharge excess air from the water tank body 1.

[0035] The heat collection return water pipe 23, the heat collection circulation pump 24, the cold water inlet pipe 17, the hot water outlet 16, the heating outlet 19, and the heating return water pipe 14 are all connected to external connecting pipes 29. The external connecting pipes 29 pass through the first insulation cavity 12 or the second insulation cavity 4 to connect to external pipelines. The second insulation cavity 4 is also provided with an electric auxiliary heater socket 30. The electric auxiliary heater socket 30 is normally closed, and an electric heater can be inserted into the water tank body 1 for auxiliary heating in climates or periods with insufficient solar energy.

[0036] Therefore, this invention employs a multifunctional solar thermal generator heat storage chamber, which achieves heat storage through the water tank itself. A heat collection system is formed by a heat collection circulation pump, a heat collection inlet pipe, and a heat collection return pipe. Hot water heated by solar energy is collected in the water tank and driven by a heating circulation pump in the heating system. The circulating water flows through the heating outlet heat exchange pipe and the heating inlet heat exchange pipe, and is heated through the heating outlet on the heating return valve. The returned water, after releasing heat, enters the circulation system from the heating return port. A water replenishment valve in the clean hot water system controls cold water to enter the hot water inlet heat exchange pipe and the hot water outlet heat exchange pipe through the cold water inlet pipe, where it is heated. Finally, clean hot water is supplied to users through the hot water outlet on the hot water return valve. This invention integrates four independent systems—solar thermal collection, heat storage, heating, and hot water—into a single, highly efficient energy storage chamber. Each circulation system operates independently, resulting in energy savings, cost reduction, and convenient installation and maintenance.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
