Description
Technical Field
[0001] The invention belongs to the technical field of solar energy combined with air energy power generation for heating and cooling, and specifically relates to a flexible combined cooling, heating and power module. Background Art
[0002] As the environmental crisis worsens, the global energy structure is shifting towards efficient, clean and diversified development. As a sustainable clean energy, solar energy is becoming increasingly important. Currently, photovoltaic power generation is used in many scenarios to provide electricity to users. However, photovoltaic panels will continuously generate heat during the power generation process. If the heat is not dissipated in time, the accumulation of heat will affect the power generation efficiency of the photovoltaic panels and also cause heat waste. For this reason, in the existing technology, a waste heat recovery unit is set in the photovoltaic power generation structure to recover the heat of the photovoltaic panels for heating users.
[0003] Evaporative cooling is a process that uses the cooling effect of water evaporation to reduce the temperature of a substance, and can provide sustainable and low-cost cooling. If an evaporative cooling structure and a photovoltaic power generation structure are set up at the same time, although power generation and heating and cooling under corresponding needs can be achieved, the evaporative cooling structure needs to be fully in contact with the air to maximize its cooling effect. In scenarios with limited installation space, it is easy to have problems such as the inability to ensure that the evaporative cooling structure is fully in contact with the air, resulting in poor cooling effect, and the large space required for installation, which leads to limitations in application scenarios. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide a flexible combined heating, cooling and power module with high integration, two working modes of solar energy utilization and air energy utilization, and the working mode can be adaptively switched with changes in temperature to optimize energy utilization, and has a compact design, high space utilization and multi-scenario adaptability.
[0005] The present invention includes a photovoltaic panel, a heat pipe, an evaporative cooling plate and a water supply pipe. The heat pipe is arranged between the photovoltaic panel and the evaporative cooling plate and is attached to the photovoltaic panel and the evaporative cooling plate, and is used to transfer cold or heat to the energy-using module. The water supply pipe is arranged on the evaporative cooling plate or connected to the evaporative cooling plate. The photovoltaic panel, the heat pipe and the evaporative cooling plate are made of bendable and deformable materials. The photovoltaic panel, the heat pipe and the evaporative cooling plate constitute a power generation module. When the temperature of the photovoltaic panel or the temperature of the space where the energy production module is located is higher than the set temperature, the energy production module is curled into a cylinder, and the side of the energy production module where the evaporative cooling plate is located is located on the outside of the cylinder, and the side where the photovoltaic panel is located is located on the inside of the cylinder. When the temperature of the photovoltaic panel or the temperature of the space where the energy production module is located is lower than the set temperature, the energy production module is unfolded, and the side of the energy production module where the photovoltaic panel is located faces outward.
[0006] Furthermore, the heat pipe is a flexible pulsating heat pipe, and the material of the flexible pulsating heat pipe is a two-way memory alloy.

[0007] Furthermore, the heat pipe is a flexible single heat pipe, and the material of the flexible single heat pipe is a two-way memory alloy. When the temperature of the photovoltaic panel is higher than the set temperature, the flexible single heat pipe undergoes adaptive bending deformation to curl the power generation module into a cylindrical shape. When the temperature of the photovoltaic panel is lower than the set temperature, the flexible single heat pipe adaptively restores its shape to unfold the power generation module.
[0008] Furthermore, the energy-using module is provided with a heat exchange water pipe, which passes through the energy-generating module and contacts one end of the heat pipe.
[0009] Furthermore, the heat pipe is a flexible separated heat pipe, which includes a heat transfer section 1 and a heat transfer section 2 connected by a pipeline, the heat transfer section 1 is arranged between the photovoltaic panel and the evaporative cooling panel and is attached to the photovoltaic panel and the evaporative cooling panel, and the heat transfer section 2 is arranged in the energy-using module; The material of the heat transfer section 1 is a two-way memory alloy. When the temperature of the photovoltaic panel is higher than the set temperature, the heat transfer section 1 undergoes adaptive bending deformation to curl the energy production module into a cylindrical shape. When the temperature of the photovoltaic panel is lower than the set temperature, the flexible heat transfer section 1 adaptively restores its shape to unfold the energy production module.
[0010] Furthermore, the middle part of the production capacity module is fixed on the mounting bracket, and the two ends of the production capacity module are bent toward the middle part under the adaptive bending deformation of the two-way memory alloy material, thereby curling into a cylindrical shape.
[0011] Furthermore, unlike the aforementioned implementation method using a two-way memory alloy material, a driving mechanism is provided to drive the energy production module to unfold or curl, and the heat pipe provided between the photovoltaic panel and the evaporative cooling panel is a flexible structure; When the temperature of the photovoltaic panel or the temperature of the space where the energy production module is located is higher than the set temperature, the driving mechanism drives the energy production module to curl into a cylinder. When the temperature of the photovoltaic panel or the temperature of the space where the energy production module is located is lower than the set temperature, the driving mechanism drives the energy production module to unfold.
[0012] Furthermore, the driving mechanism includes a screw rod, a nut and a rotating driving member, the rotating driving member is used to drive the screw rod to rotate, the threads at both ends of the screw rod are in opposite directions and are respectively provided with a nut, the middle part of the production capacity module is fixedly arranged, and the height position of the middle part of the production capacity module is lower than the screw rod, the two ends of the production capacity module are inclined or bent upward, and side frames are provided at both end portions of the production capacity module, and the side frames at both end portions are rotatably connected to the nuts at both ends of the screw rod, and the two ends of the production capacity module are driven to move by the nuts at both ends of the screw rod, so that the production capacity module can be curled or unfolded.
[0013] Furthermore, two screw rods are arranged in parallel and connected by a transmission assembly. The production capacity module is located between the two screw rods, and the side frames at both ends are rotatably connected to the nuts at both ends of the two screw rods.
[0014] Furthermore, the water supply pipe is arranged on the evaporative cooling plate, and the water supply pipe includes a shunt pipe and several branch pipes. The several branch pipes are arranged on the evaporative cooling plate at intervals along the curling direction of the energy production module. Several water supply holes are arranged on the sides of the several branch pipes. The shunt pipe edge is made of flexible material, the shunt pipe is connected to the several branch pipes, and is used to connect to the external water supply module.
[0015] The beneficial effects of the present invention are as follows: photovoltaic panels, heat pipes, and evaporative cooling plates made of bendable and deformable materials are integrated into one to form an integrated flexible structure energy production module, which has two working modes: solar energy utilization and air energy utilization. The module can be deformed according to the temperature change of the photovoltaic panel or the temperature change of the space where the energy production module is located and automatically switch the working mode, thereby realizing the three functions of power generation, heat generation, and cooling generation.
[0016] When switched to the solar energy utilization mode, the energy generation module is unfolded as a whole, with the photovoltaic panel facing outward, fully receiving solar radiation to generate electricity. Part of the electricity is stored in the battery, and part is converted into AC power through the inverter for daily use. The working heat of the photovoltaic panel is transferred to the energy-consuming module through the heat pipe to achieve power generation and heat generation, while reducing the thermal load of the photovoltaic panel, improving the utilization rate of solar energy and the power generation efficiency of the photovoltaic panel.
[0017] When switched to the working mode of utilizing air energy, the energy production module is curled into a cylinder as a whole, and the evaporative cooling plate is located on the outside of the cylinder. It can fully utilize the air energy for evaporative cooling and refrigeration, achieve cold production, and improve the utilization rate of air energy and the efficiency of evaporative cooling. The cold capacity is transferred to the energy consumption module through the heat pipe.
[0018] Compared with the setting mode of the split structure and the setting mode of the hard structure, the capacity module of the present invention has a compact design on the basis of realizing two energy utilizations and a total of three functions. The overall volume can be made smaller, and it is an integrated flexible structure, and a more reasonable functional area layout is carried out within a limited volume. The height avoidance space required when switching the working mode and the height space occupied after switching are smaller, which greatly improves the space utilization rate and solves the application limitations caused by the large size, the large floor space required when using, and the large height space required when switching the working mode. It has higher flexibility of use and more applicable scenes. It can not only be used in conventional buildings, but also adapt to the use of some small space scenes, and can also be rolled up for storage, easy to carry, and meet the installation requirements of special-shaped installation surfaces. The applicable scenes include but are not limited to conventional buildings, special-shaped buildings, RVs and ships.
[0019] In the solution of coupling the flexible pulsating heat pipe with the two-way memory alloy, it not only has excellent heat transfer performance and can transfer heat or cold to the energy-consuming module more quickly and efficiently, but the power generation module can also adaptively change to a curled or unfolded shape according to the current temperature of the photovoltaic panel, and adaptively switch between the two working modes. It can eliminate the setting of the temperature detection module and the drive mechanism, reduce the complexity of the overall structure, make the volume smaller, and further improve the overall integration, thereby further broadening the applicable scenarios and application flexibility.

[0036] like Figure 1-Figure 15As shown, the present invention provides a flexible combined cooling, heating and power module, including a photovoltaic panel 1, a heat pipe 2, an evaporative cooling plate 3 and a water supply pipe 4. The heat pipe 2 is arranged between the photovoltaic panel 1 and the evaporative panel, and is attached to the photovoltaic panel 1 and the evaporative cooling plate 3, that is, the photovoltaic panel 1, the heat pipe 2 and the evaporative cooling plate 3 are arranged in a stacked state. The water supply pipe 4 is arranged on the evaporative cooling plate 3 or connected to the evaporative cooling plate 3, and the water supply pipe 4 is used to connect the water supply module to supply water to the evaporative cooling plate 3. The photovoltaic panel 1, the heat pipe 2 and the evaporative cooling plate 3 are made of materials that can be bent and deformed. The photovoltaic panel 1, the heat pipe 2 and the evaporative cooling plate 3 form a power generation module 100, and the power generation module 100 can be deformed. Among them, the photovoltaic panel 1 is a flexible solar panel that can be bent and folded; the heat pipe 2 is made of a flexible material or a material that can be deformed at a certain temperature; the evaporative cooling plate 3 is made of a flexible material with good water absorption. The heat or cold generated by the power generation module 100 when working is transferred to the energy consumption module 200 through the heat pipe 2.
[0037] The energy production module 100 is in the shape of a plate as a whole. When the temperature of the photovoltaic panel 1 or the temperature of the space where the energy production module 100 is located is higher than the set temperature, the energy production module 100 is curled into a cylindrical shape. At this time, the side where the evaporative cooling plate 3 is located in the energy production module 100 is located on the outside of the cylindrical shape, and the side where the photovoltaic panel 1 is located is located on the inside of the cylindrical shape, that is, Figure 7 and Fig.10 When the temperature of the photovoltaic panel 1 or the temperature of the space where the energy production module 100 is located is lower than the set temperature, the energy production module 100 is unfolded, and the side of the energy production module 100 where the photovoltaic panel 1 is located faces outwards, that is, Figure 6 and Fig. 9 Status shown.
[0038] The flexible combined cooling, heating and power module provided by the present invention integrates the photovoltaic panel 1, the heat pipe 2 and the evaporative cooling plate 3 of bendable and deformable material into an integrated structure to form an integrated flexible structure energy production module 100. The photovoltaic panel 1 and the evaporative cooling plate 3 are correspondingly located on two surfaces of the integrated flexible structure energy production module 100, forming two functional areas accordingly. The integrated flexible structure energy production module 100 has two working modes of solar energy utilization and air energy utilization, and can automatically switch the working mode by deforming according to the temperature change of the photovoltaic panel 1 or the temperature change of the space where the energy production module 100 is located, thereby realizing three functions of power generation, heat generation and cooling generation.
[0039] When the solar energy utilization mode is switched, the energy generation module 100 is unfolded as a whole. Figure 6 , Fig. 9 , Fig.12 and Fig.14The photovoltaic panel 1 is in the state shown. At this time, the side where the photovoltaic panel 1 is located faces outward, fully receiving solar radiation to generate electricity. Part of the electric energy is stored in the battery 300, and part is converted into AC power for daily use through the inverter 400. When the photovoltaic panel 1 is working, the heat is transferred to the energy module 200 through the heat pipe 2 to achieve power generation and heat generation, while reducing the heat load of the photovoltaic panel 1, improving the utilization rate of solar energy and the power generation efficiency of the photovoltaic panel 1.
[0040] When the working mode is switched to air energy utilization, the energy production module 100 is rolled into a cylindrical shape as a whole. Figure 7 , Fig.10 , Fig.13 and Fig.15 At this time, the evaporative cooling plate 3 is located outside the cylinder and can be fully in contact with the air, so as to fully utilize the air energy for evaporative cooling and refrigeration, realize cooling, and improve the utilization rate of air energy and the efficiency of evaporative cooling and refrigeration. The cold energy is transferred to the energy-consuming module 200 through the heat pipe 2.
[0041] Compared with the setting mode of the split structure and the setting mode of the hard structure, the energy production module 100 of the present invention has a compact design on the basis of realizing two energy utilizations and a total of three functions. The overall volume can be made smaller, and it is an integrated flexible structure, and a more reasonable functional area layout is carried out within a limited volume. The height avoidance space required when switching the working mode and the height space occupied after switching are smaller, which greatly improves the space utilization rate, solves the application limitations caused by the large size, the large floor space required when using, and the large height space required when switching the working mode, and has higher flexibility of use and more applicable scenes. It can not only be used in conventional buildings, but also adapt to the use of some narrow space scenes, and can also be rolled up for storage, easy to carry, and meet the installation requirements of special-shaped installation surfaces. The applicable scenes include but are not limited to conventional buildings, special-shaped buildings, RVs and ships.
[0042] When the energy generation module 100 is set on the roof or outer wall of a building for use, it is in the unfolded state in the solar energy utilization working mode, and the evaporative cooling plate 3 faces the roof or outer wall, which can be used as the insulation material of the building envelope structure to increase the thermal resistance, and can reduce the heat transferred from the photovoltaic panel 1 to the room in summer, reduce the heat load of the building, and reduce the loss of indoor heat to the outside in winter. In the solar energy utilization working mode, for example, in the hot summer, if the surface temperature of the photovoltaic panel 1 is still at a certain temperature under the heat transfer of the heat pipe 2, the evaporative cooling plate 3 can also be replenished with water through the water replenishment pipe 4, and the temperature of the photovoltaic panel 1 can be lowered by the evaporative cooling effect, thereby improving the efficiency of photovoltaic power generation and reducing the heat load of the building.
[0043] In the first embodiment of the present invention, the heat pipe 2 is a flexible pulsating heat pipe, and the internal working fluid is ethylene glycol, R134a, etc. The working principle of the flexible pulsating heat pipe is based on phase change heat transfer and oscillating heat transfer. The liquid in the heating section is partially vaporized after being heated to generate steam, and the steam moves to the evaporation section under the action of the pressure difference. In the evaporation section, the steam further absorbs heat and increases the pressure to flow to the condensation section. In the condensation section, the steam releases heat and condenses into liquid, and the liquid returns to the evaporation section under the action of gravity or capillary force. Under appropriate operating conditions, the heat transfer coefficient of the flexible pulsating heat pipe can reach 2 to 5 times that of the traditional gravity heat pipe. In addition, the temperature distribution of the flexible pulsating heat pipe is uniform, which can effectively reduce the temperature gradient during the heat transfer process. Error analysis shows that the heat transfer performance of the flexible pulsating heat pipe is less affected by operating conditions and structural parameters, and has good robustness.
[0044] The material of the flexible pulsating heat pipe is a two-way memory alloy. Based on the characteristics of the two-way memory alloy, it can automatically change to a high-temperature phase shape when the temperature is higher than a certain value, and automatically restore to a low-temperature phase shape after the temperature drops below a certain value. The low-temperature phase shape of the flexible pulsating heat pipe is preset to be a flat unfolded state, and the high-temperature phase shape is a curled cylindrical shape. When the temperature of the photovoltaic panel 1 is higher than the set temperature, the flexible pulsating heat pipe undergoes adaptive bending deformation, so that the energy production module 100 is curled into a cylindrical shape. When the temperature of the photovoltaic panel 1 is lower than the set temperature, the flexible pulsating heat pipe adaptively restores its shape, so that the energy production module 100 is unfolded.
[0045] In this first embodiment, through the coupling of the flexible pulsating heat pipe and the two-way memory alloy material, the heat pipe 2 not only has excellent heat transfer performance, and can transfer heat or cold to the energy module 200 more quickly and effectively, but also has the ability to adapt to changes in shape as the temperature changes. The power generation module 100 can adaptively change to a curled or unfolded shape according to the current temperature of the photovoltaic panel 1, and adaptively switch between the two working modes. When switching the working mode, there is no need to use a temperature detection module to detect the temperature in real time, and there is no need to use a driving mechanism to apply additional external force, which can reduce the complexity of the overall structure, and the volume can be made smaller, further improving the overall integration, thereby further broadening the applicable scenarios and application flexibility.
[0046] Based on the first embodiment, the energy module 200 adapted to the energy module 100 is provided with a hot water exchange pipe 204, which passes through the energy module 100 and contacts one end of the flexible pulsating heat pipe. Figure 3The water flows along the surface of one end of the flexible pulsating heat pipe in the direction of the arrow shown. When the energy generation module 100 generates heat, the water flowing along the inside of the hot water exchange pipe 204 takes away the heat of the flexible pulsating heat pipe to provide heat for the energy consumption module 200. When the energy generation module 100 generates cold, the water flowing along the inside of the hot water exchange pipe 204 takes away the cold of the flexible pulsating heat pipe to provide cold for the energy consumption module 200.
[0047] like Figure 3 As shown, the number of flexible pulsating heat pipes is preferably two groups, and the two groups of flexible pulsating heat pipes are symmetrically arranged. In order to ensure the stability and reliability of the installation and deformation of the production capacity module 100, and at the same time ensure the effectiveness of the heat transfer performance of the heat pipe after the production capacity module 100 is deformed, as shown in FIG. Figure 6 and Figure 7 As shown, the middle of the production module 100 is fixed on the mounting bracket 8, and the two ends are not fixed to the mounting bracket 8. Under the adaptive bending deformation of the two sets of flexible pulsating heat pipes, the two ends of the production module 100 bend toward the middle, so that the production module 100 is curled into a cylindrical shape as a whole. The production module 100 can be used according to actual conditions. Figure 6 The horizontal settings shown can also be Figure 8 The specific shape and size of the mounting bracket 8 can be determined according to the actual installation requirements of the power module 100 and the heat transfer requirements of the heat pipe 2, and are not specifically limited here.
[0048] Preferably, the hot water exchange pipe 204 passes through the middle of the energy production module 100 and contacts one end of the two sets of flexible pulsating heat pipes. When the energy production module 100 is rolled and unfolded, the hot water exchange pipe 204 does not move with the deformation of the energy production module 100, which is more convenient for the connection and arrangement of the hot water exchange pipe 204. When the two ends of the energy production module 100 are bent toward the middle, the hot water exchange pipe 204 always contacts the lower end of the two sets of flexible pulsating heat pipes.
[0049] The composition structure of the energy module 200 can be referred to Fig.12 and Fig.13As shown, it includes an energy-consuming terminal 201, a hot water tank 202, a cold water tank 203 and a hot water exchange pipe 204. The hot water tank 202 and the cold water tank 203 are connected to the energy-consuming terminal 201 through a water supply pipe. The hot water exchange pipe 204 passes through the energy production module 100 and contacts one end of the flexible pulsating heat pipe, and one end of the hot water exchange pipe 204 is connected to the water inlet on the side of the hot water tank 202 and the cold water tank 203, and the other end is connected to the water outlet on the side of the hot water tank 202 and the cold water tank 203. The hot water tank 202 and the cold water tank 203 are in parallel, and the water inlet and water outlet on the side of the hot water tank 202 and the cold water tank 203 are both provided with a switch valve 1 205, and the end of the hot water exchange pipe 204 connected to the water inlet of the hot water tank 202 and the water inlet of the cold water tank 203 is provided with a temperature detection module, and the temperature detection module and all the aforementioned switch valves 1 205 are electrically connected to the external controller. When the temperature detection module detects that the water temperature in the hot water exchange pipe 204 is higher than a certain temperature, the switch valve 205 on the hot water tank 202 is opened, and the switch valve 205 on the cold water tank 203 is closed. When the temperature detection module detects that the water temperature in the hot water exchange pipe 204 is lower than a certain temperature, the switch valve 205 on the hot water tank 202 is closed, and the switch valve 205 on the cold water tank 203 is opened. In specific applications, the energy-using module 200 can also adopt other structural components for heat exchange with the energy-generating module 100 through the hot water exchange pipe 204, which is not limited here.
[0050] In the second embodiment of the present invention, the heat pipe 2 is a flexible separation type heat pipe, and the internal working fluid is ethylene glycol, R134a, etc. The flexible separation type heat pipe includes a heat transfer section 1 21 and a heat transfer section 2 22 connected by a pipeline 24, that is, the heat transfer section 1 21 and the heat transfer section 2 22 correspond to the two ends of the heat pipe 2. The heat transfer section 1 21 is arranged between the photovoltaic panel 1 and the evaporative cooling plate 3, and the heat transfer section 1 21 is attached to the photovoltaic panel 1 and the evaporative cooling plate 3, and the heat transfer section 2 22 is arranged in the energy module 200.
[0051] The material of the heat transfer section 1 21 is a two-way memory alloy. Based on the characteristics of the two-way memory alloy, the low-temperature phase shape of the heat transfer section 1 21 is preset to be a flat unfolded state, and the high-temperature phase shape is a curled cylindrical state. When the temperature of the photovoltaic panel 1 is higher than the set temperature, the heat transfer section 1 21 undergoes adaptive bending deformation, so that the energy production module 100 curls into a cylindrical shape. When the temperature of the photovoltaic panel 1 is lower than the set temperature, the heat transfer section 1 21 adaptively restores its shape, so that the energy production module 100 unfolds.
[0052] Since the heat pipe 2 adopts a separate heat pipe structure, and the heat transfer section 1 21 is coupled with the double-pass memory alloy material, the energy production module 100 can not only effectively transfer heat or cold to the energy consumption module 200 when working, but also automatically change to a curled or unfolded form according to the current temperature of the photovoltaic panel 1, so as to realize the adaptive switching of the two working modes of solar energy utilization and air energy utilization. When the energy production module 100 switches the working mode, there is no need to use the temperature detection module to detect the temperature in real time, nor is there any need to use the driving mechanism to apply additional external force, which reduces the complexity of the overall structure and further improves the overall integration. In addition, the separate heat pipe structure can realize the evaporation side and the condensation side of the heat pipe 2 to be far apart, thereby bringing more optionality to the setting method and structural design of the energy consumption module 200, and can provide users with more energy consumption side installation options.
[0053] In the second embodiment, the installation and fixing method of the production capacity module 100 is the same as that of the first embodiment, that is, the middle part is fixed on the mounting bracket 8, and under the adaptive bending deformation of the heat transfer section 1 21, the two ends of the production capacity module 100 bend toward the middle part, so that the production capacity module 100 is curled into a cylindrical shape as a whole. Figure 5 As shown, the two ends of the heat transfer section 1 21 are preferably led out from the middle of the production capacity module 100. When the production capacity module 100 is curled and unfolded, the two ends of the heat transfer section 1 21 do not move with the deformation of the production capacity module 100, which is more convenient for connecting the heat transfer section 1 21 with the heat transfer section 2 22.
[0054] Based on the second embodiment, the energy consumption module 200 adapted by the energy production module 100 has the following structure: Fig.14 and Fig.15 As shown, it includes an energy-consuming terminal 201, a hot water tank 202 and a cold water tank 203, and the hot water tank 202 and the cold water tank 203 are connected to the energy-consuming terminal 201 through a water supply pipe. A heat transfer section 2 22 is provided in each of the hot water tank 202 and the cold water tank 203, and the two heat transfer sections 2 22 are arranged in parallel and connected to the heat transfer section 1 21 through two pipelines to form a loop, and switch valves 2 23 are provided at both ends of the two pipelines connecting the two heat transfer sections 22.
[0055] Since the temperature of the working medium inside the pipeline at the parallel node position of the two heat transfer sections 22 is different in the two working modes of the capacity module 100, a temperature detection module is set at the parallel node position of the two heat transfer sections 22, and the temperature detection module and all the switch valves 2 23 mentioned above are electrically connected to the external controller. When the temperature detection module detects that the working medium is higher than a certain temperature, the heat transfer section 22 is used as the condensation side, the switch valve 2 23 connected to the heat transfer section 22 in the hot water tank 202 is opened, and the switch valve 2 23 connected to the heat transfer section 22 in the cold water tank 203 is closed. When the temperature detection module detects that the working medium is lower than a certain temperature, the heat transfer section 22 is used as the evaporation side, the switch valve 2 23 connected to the heat transfer section 22 in the hot water tank 202 is closed, and the switch valve 2 23 connected to the heat transfer section 22 in the cold water tank 203 is opened. That is, the external controller controls the switch of the corresponding switch valve 2 23 according to the temperature signal fed back by the temperature detection module, so that the switch state of each switch valve 2 23 is adapted to the current working mode.
[0056] When the production module 100 generates heat, the heat transfer section 1 21 is used as the evaporation side, and the heat transfer section 2 22 is used as the condensation side. When actually installed, the position of the hot water tank 202 is higher than the position of the production module 100. When the production module 100 generates cold, the heat transfer section 1 21 is used as the condensation side, and the heat transfer section 2 22 is used as the evaporation side. When actually installed, the position of the cold water tank 203 is lower than the position of the production module 100. Therefore, in both working modes, the condensation side of the heat pipe 2 is higher than the evaporation side.
[0057] In the third embodiment of the present invention, the heat pipe 2 is a flexible single heat pipe, and the internal working fluid is ethylene glycol, R134a, etc. The material of the flexible single heat pipe is a two-way memory alloy. Based on the characteristics of the two-way memory alloy, the low-temperature phase shape of the flexible single heat pipe is pre-set to be a flat unfolded state, and the high-temperature phase shape is a curled cylindrical state. When the temperature of the photovoltaic panel 1 is higher than the set temperature, the flexible single heat pipe undergoes adaptive bending deformation, so that the power generation module 100 is curled into a cylindrical shape. When the temperature of the photovoltaic panel 1 is lower than the set temperature, the flexible single heat pipe adaptively restores its shape to unfold the power generation module 100.
[0058] In this third embodiment, through the coupling of a flexible single heat pipe and a two-way memory alloy material, the energy production module 100 can not only effectively transfer heat or cold to the energy consumption module 200 when working, but can also automatically change to a curled or unfolded form according to the current temperature of the photovoltaic panel 1, thereby realizing adaptive switching between the two working modes of solar energy utilization and air energy utilization. When the energy production module 100 switches the working mode, there is no need to use a temperature detection module to monitor the temperature, nor is there any need to use a driving mechanism to apply additional external force, which reduces the complexity of the overall structure and further improves the overall integration, thereby further broadening the applicable scenarios and application flexibility. Compared with the flexible pulsating heat pipe of the first embodiment, the cost of the flexible single heat pipe of the third embodiment is relatively lower, which can provide users with a relatively lower cost use option.
[0059] In the third embodiment, the installation and fixing method of the production capacity module 100 is the same as that of the first embodiment, and the middle part of the production capacity module 100 is fixed on the mounting bracket 8. Under the adaptive bending deformation of the two sets of flexible pulsating heat pipes, the two ends of the production capacity module 100 bend toward the middle part, so that the production capacity module 100 is curled into a cylindrical shape as a whole. When the production capacity module 100 is used in practice, a better installation method can be selected according to actual conditions. For example, by using the mounting bracket 8 with a concave middle part and two ends tilted upward, the production capacity module 100 is installed in a concave middle part and two ends tilted upward. Figure 4 As shown, the number of flexible single heat pipes is preferably two groups, and the two groups of flexible single heat pipes are symmetrically arranged. The heat exchange water pipe 204 passes through the middle of the power generation module 100 and contacts one end of the two groups of flexible single heat pipes. When the two ends of the power generation module 100 are bent toward the middle, the heat exchange water pipe 204 always contacts the lower end of the two groups of flexible single heat pipes. In this third embodiment, the structure of the energy module 200 adapted to the power generation module 100 is the same as that of the first embodiment, and both are structural compositions for heat exchange with the power generation module 100 through the heat exchange water pipe 204.
[0060] Since about 80% of the energy reaching the surface of the photovoltaic panel 1 is converted into heat, the natural working temperature of the photovoltaic panel 1 is usually above 50°C. Although the heat pipe 2 can continuously transfer the heat of the photovoltaic panel 1, in the hot summer period, affected by the outdoor temperature, the temperature of the photovoltaic panel 1 will continue to rise, resulting in a decrease in power generation efficiency, and since this is a hot summer period, there is a need for indoor cooling. Therefore, in the above three embodiments, the deformation temperature of the heat pipe 2 can be set according to the optimal surface temperature of the photovoltaic panel 1 when it is working. Taking the deformation temperature of the heat pipe 2 as 50°C as an example, it is deformed into a high-temperature phase shape after exceeding 50°C, and the energy production module 100 is curled into a cylindrical shape, which is converted into an air energy utilization working mode, and the energy consumption module 200 is cooled by evaporative cooling to meet the corresponding cooling needs of the user. When the temperature drops, it is regarded as a decrease in the cooling demand, and the energy production module 100 returns to its original state under the deformation of the heat pipe 2 and is converted into a solar energy utilization working mode.
[0061] The fourth embodiment of the present invention is different from the above three embodiments in that Figure 8-Figure 10 As shown, the energy production module 100 is driven to deform by the driving mechanism 5. That is, the fourth embodiment of the present invention includes the driving mechanism 5, and is provided with a temperature detection module for detecting the temperature of the photovoltaic panel 1 or the temperature of the space where the energy production module 100 is located, and the temperature detection unit and the driving mechanism 5 are electrically connected to the external controller. When the temperature of the photovoltaic panel 1 or the temperature of the space where the energy production module 100 is located is higher than the set temperature, the driving mechanism 5 drives the energy production module 100 to curl into a cylindrical shape, and when the temperature of the photovoltaic panel 1 or the temperature of the space where the energy production module 100 is located is lower than the set temperature, the driving mechanism 5 drives the energy production module 100 to unfold.
[0062] In this fourth embodiment, the heat pipe 2 disposed between the photovoltaic panel 1 and the evaporative cooling plate 3 is a flexible structure. The heat pipe 2 can be a pulsating heat pipe of conventional flexible material or an ordinary heat pipe of conventional flexible material. Or the heat pipe 2 is a flexible separation heat pipe, and its heat transfer section 1 21 is disposed between the photovoltaic panel 1 and the evaporative cooling plate 3. In this fourth embodiment, since the heat pipe 2 is made of conventional flexible material, the cost is lower than that of the double-pass memory alloy material, and the processing difficulty is also lower. And the way of driving the deformation by the driving mechanism 5 is more convenient for fixing the production capacity module 100 after deformation, and the stability and operational reliability after deformation are higher.
[0063] When the heat pipe 2 is a pulsating heat pipe made of conventional flexible material or a common heat pipe made of conventional flexible material, the energy module 200 corresponding to the energy module 100 and the connection method with the energy module 200 are the same as those in the first embodiment, except that the temperature detection module is not provided on the heat exchange water pipe 204 of the energy module 200 in the fourth embodiment. When the heat pipe 2 is a flexible separation heat pipe, the energy module 200 corresponding to the energy module 100 and the connection method with the energy module 200 are the same as those in the second embodiment, except that the temperature detection module is not provided at the parallel node position of the two heat transfer sections 22 in the fourth embodiment.
[0064] The driving mechanism 5 is installed in the space where the production capacity module 100 is located. For example, when the production capacity space is set on the outer wall of the building, the driving mechanism 5 is also installed on the outer wall of the building. The driving mechanism 5 includes a screw rod 51, a nut 52 and a rotating driving member 53. The rotating driving member 53 is used to drive the screw rod 51 to rotate. Specifically, the rotating driving member 53 in the driving mechanism 5 is electrically connected to the external controller. The rotating driving member 53 is a motor or other driving member. The thread directions at the two ends of the screw rod 51 are opposite, that is, the two ends of the screw rod 51 have left-handed threads and right-handed threads respectively. The two ends of the screw rod 51 are rotatably set on the mounting bracket 8, the middle part of the mounting bracket 8 is concave and the two ends are inclined upward, and a nut 52 is provided at each end of the screw rod 51. The middle part of the production capacity module 100 is fixedly set on the mounting bracket 8. The shape of the production capacity module 100 when it is unfolded corresponds to the shape of the mounting bracket 8. When the production capacity module 100 is unfolded, the middle part is concave and the height position is lower than the screw rod 51, and the two ends are inclined or bent upward to form a corresponding pre-tension angle. The end portions of the production capacity module 100 are provided with side frames 6 to increase the strength and hardness of the end portions of the production capacity module 100. The side frames 6 at the end portions of the production capacity module 100 are rotatably connected to the nuts 52 at the two ends of the screw rod 51. When the screw rod 51 rotates, the nuts 52 at the two ends approach or move away from each other, thereby driving the two ends of the production capacity module 100 to move, so that the production capacity module 100 is curled or unfolded. Since the side frames 6 are rotatably connected to the nuts 52, and the two ends of the production capacity module 100 are arranged upward in the unfolded state, a certain pre-tension angle is formed, thereby ensuring that when the nuts 52 at the two ends of the screw rod 51 approach each other, the production capacity module 100 can be curled. Fig.10 The cylinder shown.
[0065] Preferably, two screw rods 51 are arranged in parallel, and both screw rods 51 are rotatably arranged on the mounting bracket 8. The rotating driving member 53 is arranged on the mounting bracket 8 and connected to one of the screw rods 51. The two screw rods 51 are connected by a transmission assembly 7 to maintain synchronous rotation. The transmission assembly 7 is a synchronous belt transmission assembly or a sprocket transmission assembly. The production capacity module 100 is located between the two screw rods 51. The side frame 6 at one end of the production capacity module 100 is rotatably connected to the nut 52 at one end of the two screw rods 51, and the side frame 6 at the other end of the production capacity module 100 is rotatably connected to the nut 52 at the other end of the two screw rods 51. Based on this arrangement, the consistency of movement of the two ends of the production capacity module 100 when deforming can be improved, thereby ensuring that the production capacity module 100 can achieve stable and controllable curling and unfolding under the action of the driving mechanism 5.
[0066] In the preferred embodiment 4, when the heat pipe 2 is a pulsating heat pipe made of a conventional flexible material or an ordinary heat pipe made of a conventional flexible material, two groups of pulsating heat pipes made of a conventional flexible material or an ordinary heat pipe made of a conventional flexible material are symmetrically arranged, and the arrangement of the heat exchange water pipe 204 is the same as that of the embodiment 1. When the heat pipe 2 is a flexible separation heat pipe, the two ends of the heat transfer section 1 21 are led out from the side of the middle part of the power generation module 100. When the power generation module 100 is curled and unfolded, the two ends of the heat transfer section 1 21 do not move with the deformation of the power generation module 100, which is more convenient for connecting the heat transfer section 1 21 with the heat transfer section 2 22.
[0067] In the above four embodiments, the water supply module connected to the water supply pipe 4 is also electrically connected to the external controller. When evaporative cooling is required through the evaporative cooling plate 3 , the water supply module supplies water to the water supply pipe 4 .
[0068] In the present invention, the water supply pipe 4 is arranged on the evaporative cooling plate 3, and the water supply pipe 4 includes a shunt pipe 42 and a plurality of branch pipes 41, and the plurality of branch pipes 41 are arranged on the evaporative cooling plate 3 at intervals along the curling direction of the energy production module 100. Fig.11 For example, the curling direction of the production module 100 is Fig.11 In the lateral direction of the viewing angle (i.e., the length direction of the energy production module 100), several branch pipes 41 are arranged at intervals on the evaporative cooling plate 3 along this direction. Several branch pipes 41 can be directly fixed on the surface of the evaporative cooling plate 3, or embedded in the evaporative cooling plate 3. Several water replenishment holes are arranged on the sides of the several branch pipes 41, and water flows along the water replenishment holes to the evaporative cooling plate 3. The evaporative cooling plate 3 is preferably a porous structure with stronger water absorption and water storage capacity. The shunt pipe 42 is made of flexible material and can be bent under the action of external force. The shunt pipe 42 is connected to several branch pipes 41 and is used to connect to the external water supply module. Water can be transported to several branch pipes 41 through the shunt pipe 42.
[0069] In the above four embodiments, one end of the shunt pipe 42 connected to the external water supply module is led out from the middle of the evaporative cooling plate 3, that is, Fig.11 As shown, the diverter pipe 42 is led out from the middle side of the capacity module 100. When the capacity module 100 is curled and unfolded, the end of the diverter pipe 42 does not move with the deformation of the capacity module 100, which makes it easier to connect the diverter pipe 42 with the water supply module.
