Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat pipe technology, and in particular to a solar energy two-system four-cycle heat pipe heating and heat collection system. Background Technology
[0002] Traditional solar thermal heating is limited by cloudy and rainy weather and nighttime temperature conditions. It has high auxiliary heating power consumption, and the indoor heating uses traditional radiators with low thermal efficiency. The circulating heat carrier has high temperature requirements and large circulation flow resistance. It does not fully consider the impact of the non-heating season on indoor temperature. Scale will form in the system's thermal circulation, reducing heat transfer efficiency, and corrosion will affect the system's lifespan. Therefore, traditional solar thermal heating cannot achieve low energy consumption and high efficiency. Utility Model Content

[0005] Domestic hot water heat pipe heat exchanger and heating heat pipe radiator, the domestic hot water heat pipe heat exchanger is connected to an auxiliary electric heating circulation pump;
[0006] A solar thermal collector, which is connected to a heating heat pipe radiator, is used to transfer hot water to the heating heat pipe radiator.
[0007] A solar photovoltaic power generation auxiliary heating system, wherein the solar photovoltaic power generation auxiliary heating system is connected to an electric heating container for transferring hot water to a domestic hot water heat pipe heat exchanger and a heating heat pipe radiator;
[0008] The monitoring system works in conjunction with the solar thermal collector, the auxiliary electric heating circulating pump, and the domestic hot water heat pipe heat exchanger.
[0009] Preferably, the solar collector is connected to a solar collector circulation pump for pumping cold water to the solar collector for heating.
[0010] Preferably, the solar photovoltaic power generation auxiliary heating system includes:

[0020] The condensing section is fixedly connected to the bottom end of the insulation section and is used to release the heat transferred by the evaporation section into the room.
[0021] The technical effects and advantages of this utility model are as follows:
[0022] (1) The four-way internal circulation design of the present invention is a closed loop, each circulation can work independently or in parallel, and indoor heating and domestic hot water supply can also work independently or in parallel. Not only can the indoor heat load or hot water demand be guaranteed by auxiliary electric heating, but the four sub-circuits can also be operated or shut down independently.
[0023] (2) This utility model utilizes the direct contact heat exchange between the circulating heat carrier in the heat circulation system and the heat pipe radiator and the evaporation section of the heat exchanger, making full use of the high-efficiency heat exchange characteristics of the heat pipe.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] This utility model provides, for example Figure 1-4 The solar dual-system, four-cycle heat pipe heating and heat collection system shown includes a household solar collector 1, a monitoring system 2, a solar photovoltaic auxiliary heating system 3, a hot water heat pipe heat exchanger 5, and a heating heat pipe radiator 6. The household hot water heat pipe heat exchanger 5 is connected to an auxiliary electric heating circulation pump 4. The solar collector 1 is connected to the heating heat pipe radiator 6 to transfer hot water to it. The solar photovoltaic auxiliary heating system 3 is connected to an electric heating container to transfer hot water to both the household hot water heat pipe heat exchanger 5 and the heating heat pipe radiator 6. The monitoring system 2 works in conjunction with the solar collector 1, the auxiliary electric heating circulation pump 4, and the household hot water heat pipe heat exchanger 5. The four-way internal circulation design for heat collection is a closed-loop system, and each circulation can operate independently or in parallel. Furthermore, indoor heating and household hot water supply can also operate independently or in parallel. (Specific details are as follows...) Figure 1As shown, not only can the indoor heat load or hot water demand be guaranteed through auxiliary electric heating, but the four sub-circuits can also be operated or shut down independently. The circulating heat carrier within the heat circulation system, i.e., water, directly contacts the heat pipe radiator and the evaporator section 8 of the heat exchanger for heat exchange, fully utilizing the high-efficiency heat exchange characteristics of the heat pipe. Furthermore, the condenser section 10 of the radiator heat pipe adopts a finned structure to increase the heat exchange area. The heat pipe can be installed independently, and its diameter is smaller than that of conventional flow pipes, with only the evaporator section 8 inserted within the heat circulation header. This differs from the traditional finned tube baffle system, reducing flow resistance. The monitoring system 2 enables an independent operation mechanism for auxiliary heating, and the heat pipe evaporator section 8 can operate over a wide temperature range, such as around 40℃, effectively reducing electric heating energy consumption. Both the solar photovoltaic power generation auxiliary heating and the solar collector device 1 can be bypassed for hot water extraction. A two-loop system is designed for hot water extraction to avoid direct contact between tap water and the solar collector, extending the lifespan of the solar collector.
[0033] Furthermore, the solar collector 1 is connected to a solar collector circulation pump 7, which is used to pump cold water to the solar collector 1 for heating.
[0034] Furthermore, the solar photovoltaic power generation auxiliary heating system 3 includes a solar photovoltaic panel, a controller, an energy storage component, and a true current AC inverter. The solar photovoltaic panel is connected to the controller; the energy storage component is connected to the controller to provide electricity; the true current AC inverter is connected to the electric heating container to transfer hot water to the heating pipe radiator 6; and the auxiliary electric heating circulation pump 4 is connected to the electric heating container. The electricity generated by the solar photovoltaic panel can be transferred from the controller to the energy storage component for storage, ensuring that electric heating is provided when the heating demand cannot be met by a single solar thermal collector. Under sufficient sunlight conditions, the system can store electricity or provide it for household use.
[0035] Furthermore, the heating heat pipe radiator 6 is equipped with heat pipes at equal intervals. The heat pipes include an evaporation section 8, an insulation section 9, and a condensation section 10. The evaporation section 8 acquires heat from the solar collector 1 and transfers the heat to the condensation section 10. The insulation section 9 has threads on its exterior for installation and maintenance. The heat transferred by the evaporation section 8 is released into the room. The key component of the heating heat pipe radiator 6, the heat pipe, is an independent passive heat exchange rod. The phase change heat transfer mechanism of the heat pipe determines its high-efficiency heat transfer performance, which can meet the indoor heat load requirements under conditions lower than traditional heating water temperatures. The high-efficiency heat transfer also meets the hot water supply requirements. The basic principle of the heat pipe is to achieve efficient heat transfer through phase change heat transfer from the evaporation section 8 to the condensation section 10. The evaporation section 8 acquires heat from the solar collector 1 and transfers the heat to the condensation section 10. The condensation section 10 releases the heat into the room to achieve the heating effect. To further enhance heat exchange, the condensing section 10 is designed with external fins, the evaporating section 8 is machined with external threads, and the insulation section 9 is equipped with heat-insulating fasteners and machined with external threads to facilitate convenient installation and maintenance.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
