Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to an integrated heat dissipation and heat insulation wall and greenhouse. Background Technology

[0002] With the development of modern agriculture, solar greenhouses, as important facilities for off-season planting, directly affect crop growth and yield due to their heat preservation performance. Although traditional earthen wall greenhouses have good heat preservation and storage effects, they are expensive, complex to construct, and have low land utilization. In recent years, all-steel frame solar greenhouses, which use a ground-mounted steel frame as the load-bearing structure and use rubber and plastic insulation boards, insulation blankets, and other insulation materials as wall materials, have been rapidly promoted.

[0003] The advantages of all-steel frame greenhouses include fast construction speed, less civil engineering work, and lower overall cost; the thinner wall structure greatly improves land utilization. However, all-steel frame greenhouses are characterized by "emphasizing insulation but neglecting heat storage." Traditional greenhouses have poor heat storage capacity, making it difficult to meet the overwintering production needs of warm-loving crops.

[0004] The existing technology has not adequately addressed the above issues, causing difficulties for the normal operation of this field. Therefore, there is an urgent need for an integrated heat dissipation and insulation wall and greenhouse to solve the aforementioned technical problems. Utility Model Content

[0005] This utility model proposes an integrated heat dissipation and heat insulation wall and greenhouse, which solves the problem of poor heat storage function of solar greenhouses in related technologies, which is not conducive to the overwintering production of warm-loving crops.

[0006] The technical solution of this utility model is as follows: A heat dissipation and heat insulation integrated wall includes a main layer, an insulation layer, a heat dissipation layer, a heat dissipation circulating water pipe, and a temperature sensor. The insulation layer and the heat dissipation layer are respectively disposed on both sides of the main layer. A pipe groove is opened on the heat dissipation layer, and the heat dissipation circulating water pipe is embedded in the pipe groove. The heat dissipation circulating water pipe is arranged in a serpentine coil. The temperature sensor is disposed on the heat dissipation layer.

[0007] Optionally, it also includes a water distributor, which is located on the heat collection layer, and both ends of the heat collection circulating water pipe are connected to the water distributor.

[0008] Optionally, a water storage unit is also included, which is installed on one side of the wall. The water storage unit has an outlet pipe and a return pipe, both of which are connected to the water distributor.

[0009] Optionally, it also includes a circulation pump and valves, both of which are located on the outlet pipe.

[0010] Optionally, it may also include an electric heating rod, which is disposed within the water storage unit.

[0011] A greenhouse, comprising the aforementioned integrated heat dissipation and heat insulation wall.

[0012] Optionally, the heat dissipation layer is located on the side of the main body layer facing the interior of the greenhouse.

[0013] Optionally, it also includes a heat storage circulating water pipe, which is buried in the underground soil below the greenhouse, and both ends of the heat storage circulating water pipe are connected to the water distributor.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] The walls, from the outside in, consist of an insulation layer, a main structure layer, and a heat collection layer. The main structure layer provides the necessary strength support for the walls, ensuring the stability of the greenhouse structure. The insulation layer effectively reduces heat loss within the greenhouse, maintaining the temperature at night or in low-temperature environments. The heat collection layer plays a crucial role in temperature regulation.

[0016] A groove is created in the heat collection layer to embed the heat collection and circulation water pipes. The heat collection and circulation water pipes are arranged in a serpentine coil, which reduces space occupation and increases the contact area with the heat collection layer and the air, thereby improving heat exchange efficiency. Temperature sensors are installed on the heat collection layer to monitor temperature changes in the walls and inside and outside the greenhouse in real time by preset heat collection and heat dissipation temperatures.

[0017] During the day, when there is ample sunlight and the temperature sensor detects that the temperature exceeds the collector's temperature, the control system activates the circulation pump, causing the water in the collector's circulating water pipes to begin circulating. At this time, sunlight shines on the surface of the collector layer, which absorbs solar energy and transfers heat to the water in the circulating water pipes through heat exchange. The heated water is then stored, achieving a heat storage effect.

[0018] At night or when temperatures drop, the temperature inside the greenhouse decreases. When the temperature sensor detects that the temperature is below the heat dissipation temperature, the control system restarts the circulation pump, causing the hot water in the heat dissipation circulation pipes to circulate. The hot water releases the stored heat into the greenhouse, raising the temperature and ensuring a suitable growing environment for warm-weather crops.

[0019] First, the integrated heat dissipation and insulation wall structure ensures the strength of the wall through its main layer, providing a stable supporting structure for the greenhouse. Second, the insulation layer significantly reduces heat loss and energy consumption, creating a relatively stable temperature environment for warm-climate crops. The combination of heat collection and circulation water pipes and temperature sensors on the heat collection layer enables intelligent heat collection and dissipation. During the day, it efficiently collects and stores excess heat, and at night, it releases the stored heat into the greenhouse, ensuring that the temperature inside remains within the suitable range for crop growth. This intelligent control not only improves energy efficiency but also reduces dependence on external energy sources, lowering production costs. Simultaneously, the serpentine arrangement of the heat collection and circulation water pipes reduces space occupation, increases the total area of ​​the pipes installed on the heat collection layer, and improves heat exchange efficiency. Compared to all-steel frame greenhouses, this design solves the problem of "emphasizing insulation while neglecting heat storage," meeting the overwintering production needs of warm-climate crops and providing strong technical support for the development of modern agriculture.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] Reference Figures 1-5 This is the first embodiment of the present invention, which proposes an integrated heat dissipation and heat insulation wall, including a main body layer 1, an insulation layer 2, a heat dissipation layer 3, a heat dissipation circulating water pipe 4, and a temperature sensor 5. The insulation layer 2 and the heat dissipation layer 3 are respectively disposed on both sides of the main body layer 1. A pipe groove 6 is formed on the heat dissipation layer 3, and the heat dissipation circulating water pipe 4 is embedded in the pipe groove 6. The heat dissipation circulating water pipe 4 is arranged in a serpentine coil. The temperature sensor 5 is disposed on the heat dissipation layer 3.

[0032] In this embodiment, the wall, from the outside to the inside, includes an insulation layer 2, a main body layer 1, and a heat collection layer 3. The main body layer 1 provides the necessary strength support for the wall, ensuring the stability of the greenhouse structure. The insulation layer 2 effectively reduces heat loss inside the greenhouse, maintaining the temperature inside the greenhouse at night or in low-temperature environments. The heat collection layer 3 plays an important role in temperature regulation.

[0033] A groove 6 is made in the heat collection layer 3 to embed the heat collection circulating water pipe 4. The heat collection circulating water pipe 4 is arranged in a serpentine coil, which reduces the space occupied and increases the contact area with the heat collection layer 3 and the air, thereby improving heat exchange efficiency. A temperature sensor 5 is installed on the heat collection layer 3 to monitor the temperature changes of the wall and the inside and outside of the greenhouse in real time by preset heat collection temperature and heat dissipation temperature values.

[0034] During the day, when there is ample sunlight and the temperature inside the greenhouse rises, the temperature sensor 5 detects that the temperature exceeds the heat collection temperature. The control system then activates the circulation pump 11, causing the water in the heat collection circulation pipe 4 to circulate. At this time, sunlight shines on the surface of the heat collection layer 3, which absorbs solar energy and transfers heat to the water in the circulation pipe through heat exchange. The heated water is then stored, achieving a heat storage effect.

[0035] At night or when temperatures are low, the temperature inside the greenhouse drops. When temperature sensor 5 detects that the temperature is below the heat dissipation temperature, the control system restarts circulation pump 11, causing the hot water in the heat dissipation circulation pipe 4 to circulate. The hot water releases the stored heat into the greenhouse, raising the greenhouse temperature and ensuring a suitable growing environment for warm-loving crops.

[0036] First, the integrated heat dissipation and insulation wall structure ensures the strength of the wall through the main layer 1, providing a stable supporting structure for the greenhouse. Second, the insulation layer 2 significantly reduces heat loss and energy consumption, creating a relatively stable temperature environment for warm-climate crops. The combination of heat collection and circulation water pipes 4 and temperature sensors 5 on the heat collection and insulation layer 3 enables intelligent heat collection and dissipation. During the day, excess heat is efficiently collected and stored, while at night, the stored heat is released into the greenhouse, ensuring that the temperature inside the greenhouse remains within a suitable range for crop growth. This intelligent control not only improves energy efficiency but also reduces dependence on external energy sources, lowering production costs. Simultaneously, the serpentine arrangement of the heat collection and circulation water pipes 4 reduces space occupation and increases the total area of ​​the pipes installed on the heat collection and insulation layer 3, improving heat exchange efficiency. Compared to all-steel frame greenhouses, this design solves the problem of "emphasizing insulation while neglecting heat storage," meeting the overwintering production needs of warm-climate crops and providing strong technical support for the development of modern agriculture.

[0037] Furthermore, it also includes a water distributor 7, which is located on the heat collection layer 3, and both ends of the heat collection circulating water pipe 4 are connected to the water distributor 7.

[0038] Furthermore, it also includes a water storage unit 8, which is installed on one side of the wall. The water storage unit 8 has an outlet pipe 9 and a return pipe 10, both of which are connected to the water distributor 7.

[0039] Furthermore, it also includes a circulation pump 11 and a valve 12, both of which are located on the outlet pipe 9.

[0040] Furthermore, it also includes an electric heating rod 13, which is disposed inside the water storage unit 8.

[0041] In this embodiment, the water storage unit 8 can be installed in the underground soil on one side of the greenhouse, and has an outlet pipe 9 and a return pipe 10. Both the outlet pipe 9 and the return pipe 10 are also installed in the underground soil. Both the outlet pipe 9 and the return pipe 10 are connected to the water distributor 7, thereby realizing the circulation connection between the water storage unit 8 and the heat collection and heat dissipation circulation water pipe 4. Under normal circumstances, when heat collection or heat dissipation circulation is required, the valve 12 is opened and the circulation pump 11 is started. The circulation pump 11 provides power for water circulation, so that water circulates between the water storage unit 8, the outlet pipe 9, the water distributor 7, the heat collection and heat dissipation circulation water pipe 4, and the return pipe 10.

[0042] When the sunlight is strong, the water in the heat collection and circulation pipe 4 absorbs heat, and its temperature gradually rises. At the same time, the water storage unit 8, buried in the underground soil of the greenhouse, is also connected to the heat collection and circulation pipe 4 through the outlet pipe 9, the return pipe 10, and the water distributor 7. At this time, the hot water in the heat collection and circulation pipe 4 flows into the water storage unit 8, storing the heat in the underground soil.

[0043] At night or when temperatures are low, the temperature inside the greenhouse begins to drop. When temperature sensor 5 detects that the temperature is below the heat dissipation temperature, the control system starts the circulation pump 11, causing the water in the water storage unit 8 to circulate. Hot water flows out from the water storage unit 8 in the underground soil, passes through the water distributor 7, and flows into the heat collection and circulation water pipe 4, releasing the heat from the water storage unit 8 into the greenhouse, raising the greenhouse temperature, and providing a suitable growing environment for heat-loving crops.

[0044] When there are consecutive cloudy days without sunlight, the temperature inside the greenhouse may drop. In this case, the electric heating rod 13 located in the water storage unit 8 is activated. The electric heating rod 13 begins to work, heating the water in the water storage unit 8. The heated water, under the action of the circulation pump 11, flows through the outlet pipe 9 into the water distributor 7, and then into the heat collection and circulation water pipe 4, releasing heat into the greenhouse as an auxiliary heating measure to ensure that the temperature inside the greenhouse remains stable within a range suitable for crop growth.

[0045] First, the installation of the water storage unit 8, the circulating pump 11, and the valve 12 ensures stable water circulation in the heat collection and dissipation circulating water pipe 4, enabling timely heat collection and dissipation as needed, thus improving the efficiency and reliability of temperature regulation. Second, the installation of the electric heating rod 13 provides auxiliary heating in the greenhouse under special circumstances such as continuous cloudy days, ensuring that the temperature inside the greenhouse does not drop too low, providing a stable environment for crop growth, and reducing the adverse effects of weather factors on agricultural production.

[0046] A greenhouse, comprising the aforementioned integrated heat dissipation and heat insulation wall.

[0047] Furthermore, the heat dissipation layer 3 is located on the side of the main body layer 1 facing the interior of the greenhouse.

[0048] Furthermore, it also includes a heat storage circulating water pipe 14, which is buried in the underground soil below the greenhouse, and both ends of the heat storage circulating water pipe 14 are connected to the water distributor 7.

[0049] In this embodiment, an integrated heat collection and insulation wall is used to construct the greenhouse. The heat collection layer 3 is located on the side of the main layer 1 facing the interior of the greenhouse, so that during the daytime, sunlight can directly reach the heat collection circulation water pipe 4 on the heat collection layer 3. When the sunlight is strong, the water in the heat collection circulation water pipe 4 absorbs heat, and its temperature gradually rises. At the same time, the heat storage circulation water pipe 14 buried in the underground soil below the greenhouse is also connected to the heat collection circulation water pipe 4 through a water distributor 7. At this time, the hot water in the heat collection circulation water pipe 4 flows into the heat storage circulation water pipe 14, storing the heat in the underground soil.

[0050] At night or when temperatures are low, the temperature inside the greenhouse begins to drop. When temperature sensor 5 detects that the temperature is below the heat dissipation temperature, the control system starts the circulation pump 11, causing the water in the heat storage circulation pipe 14 to circulate. Hot water flows out from the underground soil, passes through the water distributor 7, and flows into the heat collection circulation pipe 4, releasing the heat from the heat storage circulation pipe 14 into the greenhouse, raising the greenhouse temperature and providing a suitable growing environment for heat-loving crops.

[0051] First, the heat collection layer 3 is positioned on the side of the main layer 1 facing the interior of the greenhouse, allowing sunlight to directly illuminate the heat collection circulation water pipe 4, thus integrating the solar heat collection function. Compared to traditional solar heat collection methods, no additional structure is required, reducing construction costs and space occupation. Second, a heat storage circulation water pipe 14 is installed underground in the greenhouse, forming a groundwater circulation heat storage system. The underground heat storage circulation water pipe 14 is connected in series with the heat collection circulation water pipe 4 inside the heat collection layer 3 via a water distributor 7, forming a closed water circuit, achieving efficient heat storage and release. This design improves energy utilization efficiency, reduces dependence on external energy sources, and provides strong support for the sustainable operation of the greenhouse. Simultaneously, the groundwater circulation heat storage system also has the advantages of good stability and small temperature fluctuations, providing a more stable growing environment for crops.
