Description

Technical Field

[0001] This utility model relates to the field of solar collector technology, specifically an integrated solar collector. Background Technology

[0002] A solar collector is defined as a device that absorbs solar radiation and transfers the generated heat energy to a heat transfer medium. This concise definition contains a wealth of meaning: First, a solar collector is a device; second, a solar collector can absorb solar radiation; third, a solar collector can generate heat energy; and fourth, a solar collector can transfer heat energy to a heat transfer medium. Although solar collectors are not directly consumer-facing end products, they are key components of various solar thermal utilization systems. Whether it's solar water heaters, solar cookers, active solar houses, solar greenhouses, solar drying, solar industrial heating, or solar thermal power generation, all rely on solar collectors, using them as the power source or core component of the system.

[0003] Existing solar collectors only have an outdoor heat collection and insulation cylinder, which needs to provide both domestic and heating water. Therefore, the two pipes on top are used for domestic and heating water respectively. This leads to insufficient heat exchange for heating, causing the outdoor heat collection system to overheat and "boil over." When the water reaches 100 degrees Celsius, steam will be produced, which will cause the water level to drop. The drop in water level will then cause the water supply switch to frequently replenish water, resulting in uneven outdoor temperature. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated solar collector to solve the problems mentioned in the background. This invention features a novel structure, adding an indoor energy-saving insulation cylinder to reduce the number of outdoor heat collection systems. The heating heat exchange adopts a dual-loop design, resulting in more thorough heat exchange, more balanced outdoor system temperature, and higher heat exchange efficiency. Since the indoor water inlet is close to the water collection point, the waiting time for hot water can be reduced, solving the problem of domestic water use in summer. In summer, this is achieved through a manual three-way valve, a short-circuit pipe, and the switching of the main and auxiliary control circuits.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated solar collector includes an outdoor heat-collecting and insulation cylinder, wherein multiple sets of outdoor heat-collecting and insulation cylinders are provided, and exhaust pipes are connected in series between the multiple sets of outdoor heat-collecting and insulation cylinders. Multiple sets of heat exchange pipes are provided at the bottom of the exhaust pipes, and the heat exchange pipes of the multiple sets of outdoor heat-collecting and insulation cylinders are connected. Vacuum heat-collecting tubes are fixedly installed at equal intervals at the bottom of the outdoor heat-collecting and insulation cylinder. A water pipe is fixedly connected to one end of the outdoor heat-collecting and insulation cylinder, and an energy-saving insulation cylinder is fixedly connected to the other end of the water pipe. The energy-saving insulation cylinder is arranged indoors, and multiple sets of radiators are connected to the energy-saving insulation cylinder through pipes.

[0006] Furthermore, a corrugated coil is fixed inside the energy-saving insulation cylinder, and one end of the corrugated coil inside the energy-saving insulation cylinder is connected to a domestic water inlet, while the other end of the corrugated coil inside the energy-saving insulation cylinder is connected to a domestic water outlet.

[0007] Furthermore, a nanofilm heating tube is inserted and installed inside the energy-saving heat-insulating cylinder, and a secondary control module is provided on the outside of the energy-saving heat-insulating cylinder. A heating tube solenoid valve is provided in the circuit between the secondary control module and the nanofilm heating tube.

[0008] Furthermore, a main control module is also provided on the outside of the energy-saving insulation cylinder, and a double switch is installed between the main control module and the secondary control module.

[0009] Furthermore, a control circuit is installed between the energy-saving insulation cylinder and the outdoor heat-collecting insulation cylinder.

[0010] Furthermore, the energy-saving insulation cylinder is connected to the radiator via a pipe, and a one-way manual three-way valve is installed on the connecting pipe between the energy-saving insulation cylinder and the radiator.

[0011] Furthermore, the other end of the one-way manual three-way valve is equipped with a short-circuit pipe, and the short-circuit pipe is connected to the outdoor heat collection and insulation cylinder.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model can switch the connection method of the radiator through a one-way manual three-way valve. It can be connected to an outdoor heat collection and insulation cylinder to provide heating by using the heat generated by solar energy, or it can use the heat inside the energy-saving insulation cylinder for heating.

[0014] 2. This utility model allows switching between the main control module and the secondary control module via a dual-switch. The secondary control module controls the nanofilm heating tube to heat the water in the energy-saving insulation cylinder, assisting the outdoor heat collection system in conducting heat to the radiators. The nanofilm heating tube is characterized by its non-scale-forming and high thermal efficiency. The secondary control module of the indoor energy-saving insulation cylinder is used to control the water temperature inside the cylinder, while the main control module is used to control the indoor heating temperature in winter.

[0015] 3. This utility model connects to the corrugated coil through the domestic water inlet and outlet to replenish the water inside the energy-saving insulation cylinder, and can improve the heat exchange efficiency through the corrugated coil.

[0016] 4. Compared with the prior art, this utility model adds an indoor energy-saving heat insulation cylinder, which can reduce the number of outdoor heat collection systems. The heating heat exchange adopts a dual-loop system, which makes the heat exchange more complete, the temperature of the outdoor system is more balanced, and the heat exchange efficiency is higher. Since the indoor water inlet is closer to the water intake point, the waiting time for hot water can be reduced, which solves the problem of domestic water use in summer. In summer, it is achieved by using a manual three-way valve, a short-circuit pipe, and the switching of the main and auxiliary control circuits. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: an integrated solar collector, including an outdoor heat-collecting and insulation cylinder 3. Multiple sets of outdoor heat-collecting and insulation cylinders 3 are provided, and exhaust pipes 1 are connected in series between these sets. Multiple sets of heat exchange pipes 2 are installed at the bottom of the exhaust pipes 1, and the heat exchange pipes 2 of the multiple sets of outdoor heat-collecting and insulation cylinders 3 are connected. Vacuum heat-collecting pipes 4 are fixedly installed at equal intervals at the bottom of the outdoor heat-collecting and insulation cylinder 3. A water pipe 5 is fixedly connected to one end of the outdoor heat-collecting and insulation cylinder 3, and an energy-saving insulation cylinder 12 is fixedly connected to the other end of the water pipe 5. The energy-saving insulation cylinder 12 is arranged indoors and is connected to multiple sets of radiators 9 through pipes. The outdoor heat-collecting and insulation cylinder 3 is similar to existing technologies, using heat exchange pipes 2 and exhaust pipes... 1 and vacuum collector tube 4 form an outdoor heat collection system. The heat absorbed by the vacuum collector tube 4 is exchanged with the water inside the outdoor heat collection insulation cylinder 3 through the heat exchange pipe 2. It can be directly transported to the position of the radiator 9 through the pipe connection to provide indoor heating. The outdoor heat collection insulation cylinder 3 and the energy-saving insulation cylinder 12 are connected to the outdoor and indoor areas through the water pipe 5. Automatic water replenishment and the addition of the indoor energy-saving insulation cylinder 12 can reduce the number of outdoor heat collection systems. The heating heat exchange adopts a dual-loop system, which makes the heat exchange more complete, the temperature of the outdoor system is more balanced, and the heat exchange efficiency is higher. Since the indoor water intake is close to the water intake point, the waiting time for hot water can be reduced when taking water, which solves the problem of domestic water in summer. In summer, it is achieved by manual three-way valve, short-circuit pipe 7 and main and auxiliary control circuit switching.

[0024] In this embodiment, a corrugated coil is fixed inside the energy-saving insulation cylinder 12, and one end of the corrugated coil inside the energy-saving insulation cylinder 12 is connected to a domestic water inlet 10, and the other end of the corrugated coil inside the energy-saving insulation cylinder 12 is connected to a domestic water outlet 11. The domestic water inlet 10 and the domestic water outlet 11 are connected to the corrugated coil to replenish the water inside the energy-saving insulation cylinder 12, and the heat exchange efficiency can be improved through the corrugated coil.

[0025] In this embodiment, a nanofilm heating tube 13 is inserted and installed inside the energy-saving heat-insulating cylinder 12. A secondary control module 17 is provided on the outside of the energy-saving heat-insulating cylinder 12, and a heating tube solenoid valve 14 is provided in the circuit between the secondary control module 17 and the nanofilm heating tube 13. A main control module 16 is also provided on the outside of the energy-saving heat-insulating cylinder 12. A double switch 15 is installed between the main control module 16 and the secondary control module 17. A control circuit 6 is installed between the energy-saving heat-insulating cylinder 12 and the outdoor heat-collecting heat-insulating cylinder 3. The use of the double switch 15 can switch between the use of the main control module 16 and the secondary control module 17. The secondary control module 17 controls the nanofilm heating tube 13 to heat the water in the energy-saving heat-insulating cylinder 12, assisting the outdoor heat collection system in conducting heat to the radiator 9. The nanofilm heating tube 13 has the characteristics of not forming scale and high thermal efficiency. The secondary control of the indoor energy-saving heat-insulating cylinder 12 is used to control the water temperature inside the energy-saving heat-insulating cylinder 12, and the main control is used to control the indoor heating temperature in winter.

[0026] In this embodiment, the energy-saving insulation cylinder 12 is connected to the radiator 9 via a pipe, and a one-way manual three-way valve 8 is arranged on the connecting pipe between the energy-saving insulation cylinder 12 and the radiator 9. The other end of the one-way manual three-way valve 8 is equipped with a short-circuit pipe 7, which is connected to the outdoor heat collection insulation cylinder 3. The connection mode of the radiator 9 can be switched through the one-way manual three-way valve 8. It can be connected to the outdoor heat collection insulation cylinder 3 to use the heat generated by solar energy for heating, or it can use the heat inside the energy-saving insulation cylinder 12 for heating.

[0027] Adding an indoor energy-saving insulation cylinder 12 reduces the number of outdoor heat collection systems. The heating heat exchange uses a dual-loop system, resulting in more thorough heat exchange, more balanced outdoor system temperature, and higher heat exchange efficiency. Since the indoor water inlet is closer to the water intake point, the waiting time for hot water is reduced, solving the problem of domestic water use in summer. In summer, this is achieved through a manual three-way valve, short-circuit pipe 7, and main / secondary control circuit switching. The main control module 16 or secondary control module 17 can be switched using a double-switch switch 15. The secondary control module 17 controls the nanofilm heating tube 13 to heat the water in the energy-saving insulation cylinder 12, assisting the outdoor heat collection system in conducting heat to the radiators 9. The nanofilm heating tube 13 is characterized by its non-scale-forming and high thermal efficiency. The secondary control of the indoor energy-saving insulation cylinder 12 is used to control the water temperature inside the energy-saving insulation cylinder 12, while the main control is used to control the indoor heating temperature in winter. The domestic water inlet 10 and domestic water outlet 11 are connected to the corrugated coil to replenish the water volume inside the energy-saving insulation cylinder 12, and the corrugated coil can also improve the heat exchange efficiency.
