At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] refer to Figure 1-3 The utility model provides a heat control system based on a heat pipe heat collection wall, comprising a heat collection wall, a two-color heat collection pipe (3), a rotary control device, a heat storage tank (7) and a hot water storage tank (18). The heat collection wall adopts a transparent glass cover plate (1) to form an outer wall surface, and an extruded polystyrene insulation board (26) and a solid wall (27) to form an inner wall of the building.

[0029] A heat storage tank (7) is provided on the top of the interlayer, and the condensation end (6) of the internal heat pipe and the heat exchange coil (5) form a heat exchange device, which can preheat water to enter the household hot water storage tank (18). At the same time, the condensation end (6) of the heat pipe can exchange heat with the surrounding air. When the solar radiation is weak in winter, the interlayer can still form a temperature difference, and the heat pressure is used to accelerate indoor heating. The inner wall of the building can absorb heat energy for storage during the day in winter, and release heat at night to achieve indoor heating. The upper and lower parts of the heat collection wall are provided with adjustable louver vents, and the upper part of the transparent glass cover plate (1) is an outer air outlet (9), and the lower part is an outer air inlet (13). The upper part of the inner wall of the building is provided with an internal air outlet (10) and a heat storage air outlet (12) connected to the heat storage tank (7), and the lower part is provided with an internal air inlet (14). The circulating water circuit includes a main water valve (16), a first branch valve (17), a second branch valve (19) and a water pump (15).

[0030] The two-color heat collecting tube (3) is a heat pipe type vacuum heat collecting tube, which is arranged in parallel and fixed and regulated by means of a bayonet at the bottom of the heat storage tank and a rotating control device. The left and right sides of the two-color heat collecting tube (3) have different internal film layers, one side of which is a traditional black selective absorption coating, and the other side of which is an anti-reflective white coating, thereby realizing the functions of heat collection and heating in winter and reflective cooling in summer.

[0031] The bottom rotation control device is connected and fixed to the wall through the bottom bolts (24); the stepping motor (22) transmits power to the gear (23) through the transmission shaft; the gear (23) is arranged horizontally to drive the bottom rotating platform of the two-color heat collecting tube (3) to rotate; the rotation strategy is adjusted in different seasons so that the black heat collecting surface of the two-color heat collecting tube (3) faces or turns away from the sun surface, thereby effectively controlling the solar energy collection efficiency and ensuring the stability of the indoor environment.

[0032] The gears (23) are located at the bottom of the two-color heat collecting tubes (3) in one-to-one correspondence. Each gear (23) has the same size and a transmission ratio of 1:1, which can ensure that the adjustment angles of multiple two-color heat collecting tubes (3) arranged in parallel are consistent, thereby achieving precise control of the heat collecting tubes.

[0033] The heat storage box (7) is made of a coated steel plate, and is coated with a heat-insulating coating on the upper side. A circular fixing socket for a two-color heat collecting tube (3) is provided at the lower part. The upper side can exchange heat with the external air duct, forming a local high temperature in the external air duct, and utilizing heat pressure to accelerate indoor heating.

[0034] The heat storage tank (18) is equipped with a heating device (20) inside. When the sunlight is insufficient for a long time, the heating device (20) can be used to meet the demand for hot water and realize indoor heating at the same time.

[0035] The outer air outlet (9), the outer air inlet (13) and the inner air inlet 10 are all adjustable louver air outlets, and the outside of the air outlets are all provided with dust covers, which can effectively prevent garbage in the outdoor air from entering.

[0036] The heat storage tank (7) and the hot water storage tank (18) are connected via a circulating water circuit, wherein the circulating water circuit uses stainless steel or copper pipes, and the pipe diameter is determined according to the design requirements of the system and the thermal efficiency calculation. This connection enables the heat in the heat storage tank to be transferred to the hot water storage tank through the medium in the circulating water circuit, thereby realizing the storage and redistribution of heat. A main valve (16), a first branch valve (17) and a second branch valve (19) are arranged in the middle of the circulating water circuit to control the direction and flow of water flow.

[0037] The hot water storage tank (18) is provided with a heating device (20) inside. The heating device (20) selects a suitable heating method according to the required heating efficiency and installation conditions. The heating device (20) is installed at the bottom of the hot water storage tank (18) to promote uniform heat distribution. When the system needs to heat the water in the hot water storage tank (18), the heating device (20) starts to work, and at the same time, the water pump (15) in the circulating water circuit is started to circulate the water in the hot water storage tank (18). During the heating process, the power of the heating device (20) can be adjusted according to the water temperature in the hot water storage tank (18) to achieve the purpose of efficient heating and energy saving, and realize the coordinated work of the hot water storage tank (18), the circulating water circuit and the heating device (20).

[0038] Furthermore, the utility model is also equipped with indoor and outdoor temperature sensors, which can monitor the ambient temperature in real time and automatically adjust the working mode according to the seasons and day and night changes, including four working modes: winter day, winter night, summer day and summer night.

[0039] In the winter daytime working state, the system operation diagram is as follows Figure 5 As shown. At this time, the indoor wind enters the system from the internal air inlet (14), and the heat absorption surface of the two-color heat collecting tube (3) receives solar radiation and transfers heat to the condensing end (6) at the top. The bottom rotating device sets a rotation strategy to keep the heat absorption surface of the heat collecting tube always facing the sunlight. The small fan (8) is turned on to allow the air to fully exchange heat with the condensing end (6), and the heated air is sent into the room through the heat storage outlet (12), accelerating the increase of indoor temperature. The air in the heat storage tank (7) is heated under the action of the condensing end (6). At the same time, the top of the heat storage tank 3 and the air at the top of the external air duct (2) are subjected to convective heat exchange, so that the air at the top of the external air duct (2) is heated, the temperature difference between the upper and lower parts is increased, and the air flow rate inside the air duct is accelerated. Part of the hot air flows through the internal air outlet (10) into the room for heating. When the indoor temperature reaches the heating temperature, the small fan (8) and the first branch valve (17) are turned off. The replenishing water passes through the heat exchange coil (5) and enters the hot water storage tank (18). The heat exchange coil (5) exchanges heat with the condensation end (6), and the cold water in the coil absorbs heat and is heated to hot water, which then enters the hot water storage tank (18) and becomes domestic hot water for use. At this time, the outer air duct (2) and the inner air duct (4) are naturally ventilated under the chimney effect.

[0040] In the working state at winter night, the operation diagram of the system is as follows Figure 6As shown. At this time, the heat collecting wall is in passive operation, and the indoor wind enters the system from the internal air inlet (14). The heat storage wall releases latent heat, heats the air passing through the surface, and sends the heat into the room. When the indoor temperature reaches the set temperature, the system controls and adjusts all the air outlets to remain closed. If the indoor temperature does not reach the comfortable temperature at night, the water pump (15) can be turned on and the main water supply valve (16) can be closed to allow hot water to circulate through the heat exchange coil (5) to release heat, thereby increasing the temperature of the air entering the room. If necessary, the heating device (20) can be turned on to improve the heat exchange effect.

[0041] In the summer daytime working state, the system operation diagram is as follows Figure 7 As shown. At this time, the first branch valve (17) of the water supply pipeline is closed, the water pump (15) is turned off, and the supply water passes through the heat exchange coil (5) and then enters the hot water storage tank (18) through the second branch valve (19). The reflective surface of the two-color heat collecting tube (3) faces the sun, and the reflective surface of the heat collecting tube is always facing the sunlight through the bottom rotating device. Part of the solar radiation is reflected, and the remaining absorbed heat is transferred to the condensation end (6). The heat is absorbed by the cold water after passing through the heat exchange coil (5) and enters the hot water storage tank (18), or enters the external air duct (2) under the action of the small fan (8), and is discharged outdoors through the peripheral air outlet (9).

[0042] In the working state at summer night, the operation diagram of the system is as follows Figure 8 At this time, the internal air inlet (14) is opened, and the replenishing water passes through the heat exchange coil (5) and then enters the hot water storage tank (18) through the second branch valve (19). At the same time, the heat in the solar wall is brought to the outside by the indoor and outdoor air, causing the temperature in the solar wall to drop to the set temperature, and then the active equipment is turned off, and all air outlets are controlled and adjusted to remain in a closed state.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
