Description

Technical Field

[0001] This utility model relates to the field of solar energy antifreeze technology, and in particular to an antifreeze device for a flat-plate solar thermal collector system. Background Technology

[0002] Solar thermal collection systems are widely used in building heating, hot water supply, and other fields. Especially in modern society, where energy conservation and environmental protection are increasingly valued, the application prospects of solar thermal collection technology are very broad. However, traditional flat-plate solar thermal collection systems face a critical problem in cold regions—freezing prevention. Under low-temperature conditions, the fluids in the collection system (such as water or heat transfer fluid) are prone to freezing, leading to pipe blockages and ruptures, severely affecting the normal operation of the collection system and even damaging the equipment. Therefore, freezing prevention is an important guarantee for the normal operation of solar thermal collection systems in cold climates.

[0003] The existing patent application CN212842283U, entitled "A Solar Flat-Plate Antifreeze Collector," includes: a circulating water pipe, a water tank, a circulating water pump, a solar collector plate, a pressure-bearing hose, a storage tank, and a pipe separation device. The circulating water pipe includes a collector section and a connecting section. The water tank is connected to both ends of the collector section via the connecting section. The circulating water pump is installed on the connecting section. The collector section is placed within the solar collector plate. One end of the pressure-bearing hose is connected to the storage tank, and the other end of the pressure-bearing hose passes through the collector section and is connected to the storage tank. The storage tank is filled with an antifreeze medium. The circulating water pipe has an inlet point and an outlet point. The pipe separation device is installed at the inlet point and the outlet point of the pressure-bearing hose. Compared to existing technologies, this invention can prevent damage to the copper pipes inside the flat-plate core due to freezing of the internal circulating water, thus extending its service life.

[0004] Existing solar thermal systems mostly rely on simple physical insulation materials for protection. However, these methods often fail to provide sufficient antifreeze in extremely cold weather, leading to low system efficiency or frequent malfunctions. Furthermore, traditional systems lack effective real-time monitoring and adjustment mechanisms for temperature changes, making it impossible to dynamically adjust the system according to actual environmental temperature variations, which can easily result in overheating or insufficient protection. This not only affects system efficiency but also increases maintenance costs. Therefore, we provide an antifreeze device for flat-plate solar thermal systems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an antifreeze device for flat-plate solar thermal collector systems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flat-plate solar thermal collector system antifreeze device, comprising: a solar energy mechanism, the solar energy mechanism including a housing, a solar panel disposed on the housing, an infusion pipe disposed in the housing, a three-way valve disposed at one end of the infusion pipe, a heating pipe disposed between the two three-way valves, a heating plate disposed on the heating pipe, and an antifreeze mechanism disposed on the side of the heating pipe away from the heating plate;

[0012] In a preferred embodiment, the two sides of the control valve are respectively connected to the transfer pipe and the dispersion pipe, and the bottom of the dispersion pipe is connected to the heat-laying pipe.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model uses a hot air gun inside the casing to deliver hot air to the dispersion tube through the transfer pipe in the workbench for heating. After the hot air is dispersed in the dispersion tube, the heat is conducted to the heat-laying tube. In order to maintain the heat and improve the heating effect, the outer surfaces of the dispersion tube and the heat-laying tube are provided with a heat-insulating cotton layer. Through this design, the infusion tube, the three-way valve and the heating tube can be effectively insulated and heated, thereby significantly improving the practicality of the device in actual use.

Whether in cold nights or in low-temperature environments, the device can work efficiently and ensure stable temperatures in all parts, making it suitable for more diverse practical application scenarios and further enhancing its competitiveness in the market.

[0029] Example 1

[0030] like Figures 1-5As shown, this utility model provides a technical solution: a flat-plate solar thermal collector system antifreeze device, including: a solar energy mechanism 1, the solar energy mechanism 1 including a housing 11, a solar panel 12 disposed on the housing 11, an infusion pipe 13 disposed in the housing 11, a three-way valve 14 disposed at one end of the infusion pipe 13, a heating pipe 15 disposed between the two three-way valves 14, a heating plate 16 disposed on the heating pipe 15, and an antifreeze mechanism 2 disposed on the side of the heating pipe 15 away from the heating plate 16;

[0031] The antifreeze mechanism 2 includes a protective frame 21, in which a hot air gun 22 is installed. One end of the hot air gun 22 is connected to a workbench 23. A transfer pipe 24 is installed at the end of the hot air gun 22 that passes through the workbench 23. A control valve 25 is installed at one end of the transfer pipe 24. A dispersion pipe 26 is installed on the control valve 25. A heat-laying pipe 27 is installed at the bottom of the dispersion pipe 26.

[0032] The solar panel 12 is laid on the casing 11. The outer surface of the infusion tube 13 is nested in the casing 11. One end of the infusion tube 13 is connected to the three-way valve 14. Both ends of the heating tube 15 are connected to the three-way valve 14. The heating plate 16 is fitted on the outer surface of the heating tube 15. The outer surfaces of the infusion tube 13, the three-way valve 14, and the heating tube 15 are all nested in the insulation cotton layer 17. The outer surface of the protective frame 21 is nested in the casing 11. The bottom end of the hot air gun 22 is fixedly connected to the casing 11. One end of the hot air gun 22 is connected to the workbench 23. The adapter tube 24 passes through the workbench 23 and is connected to the hot air gun 22. The two sides of the control valve 25 are connected to the adapter tube 24 and the dispersion tube 26, respectively. The bottom of the dispersion tube 26 is connected to the heat-laying tube 27.

[0033] In this embodiment, when the staff uses this solar energy device for heating, at night or in some low-temperature conditions, the staff can start the hot air gun 22 in the casing 11 and let it pass through the adapter pipe 24 in the workbench 23 to heat the dispersion pipe 26. After the heat transmission is completed, the dispersion pipe 26 will transmit heat to the heat-laying pipe 27. The outer surfaces of the dispersion pipe 26 and the heat-laying pipe 27 are provided with a heat-insulating cotton layer 17, which can keep the infusion pipe 13, the three-way valve 14 and the heating pipe 15 warm, thus further improving its practicality in actual use.

[0034] Working principle:

[0035] like Figures 1-5As shown, when staff use this solar energy device for heating, heat can be provided by activating the hot air gun 22 in the casing 11 at night or in low-temperature conditions. The hot air gun 22 delivers hot air to the dispersion tube 26 through the adapter tube 24 in the workbench 23. After dispersing the hot air, the dispersion tube 26 conducts the heat to the heat-laying tube 27. To improve the insulation effect, the outer surfaces of both the dispersion tube 26 and the heat-laying tube 27 are provided with an insulation layer 17. This insulation layer can effectively insulate and heat the infusion tube 13, the three-way valve 14, and the heating tube 15, thereby improving the practicality of the device in actual use.

[0036] Furthermore, to further optimize the device's performance, a temperature sensor and an intelligent control system can be added. The temperature sensor can monitor the temperature of each component in real time, and the intelligent control system can automatically adjust the operating status of the hot air gun 22 according to the set temperature range, ensuring that the device operates under optimal temperature conditions. These improvements not only increase heating efficiency but also save energy and extend the equipment's lifespan.

[0037] These improvements enable solar energy devices to operate efficiently under various environmental conditions, significantly enhancing their practicality and reliability, and making them suitable for a wider range of applications.
