[0049] Solar collector systems absorb solar radiation and convert it into heat. Currently, the control process for these systems is very simple, making them inadequate for the complex and diverse user scenarios and needs.

[0050] In view of this, the embodiments of the present application provide a heat collection system and a heat collector, which are conducive to extending the flow path of the target medium in the guide component, improving the heat exchange efficiency of the heat collection system, improving the heat absorption component, and / or the matching degree between the working state of the guide component and the user's usage scenario and usage requirements, thereby improving the user experience.

[0051] According to a first aspect of the embodiments of the present application, the present application proposes a heat collection system. Figure 1-3 This is a structural diagram of a heat collection system 100 provided in an embodiment of the present application. Figure 1-3 As shown, the system 100 may include: a heat absorption component 110 , a flow guide component 120 and a regulation component 130 .

[0052] The heat absorption component 110 is used to absorb solar energy and convert it into thermal energy.

[0053] Exemplarily, the heat absorption component 110 may include a heat absorption plate for absorbing solar radiation energy and converting the radiation energy into heat energy.

[0054] The flow guide assembly 120 is connected to the heat absorption assembly 110 and is used to transport the target medium so that the target medium and the heat absorption assembly 110 can exchange heat. The flow guide assembly 120 includes: multiple DC components 121 and multiple deflection components 122. The deflection components 122 are arranged between the DC components 121 to make the flow guide channel serpentine.

[0055] For example, the flow guide assembly 120 can be connected to the heat absorbing plate to exchange heat between the target medium and the heat absorbing plate. The target medium may include water, antifreeze, or oil. It should be noted that the flow guide assembly 120 and the heat absorbing assembly 110 may be provided with aluminum strips to improve heat exchange efficiency.

[0056] Illustratively, the DC component 121 may include a DC pipe. The baffle component 122 may include a baffle pipe. It should be noted that the baffle pipe is configured as an arc-shaped pipe, wherein the chamfer radius of the arc-shaped pipe is positively correlated with the pipe diameter of the DC pipe to avoid dead zones or uneven flow rates during the flow of the target medium.

[0057] Specifically, the curved pipes are positioned between the DC pipes, creating a serpentine-shaped flow channel within the flow guide assembly 120. It should be noted that the flow guide assembly 120 comprises a plurality of DC components 121 and a plurality of baffle components 122. The baffle components are positioned between the DC components 121, creating a serpentine-shaped flow channel. This helps extend the flow path of the target medium within the flow guide assembly 120, increases the target medium's residence time within the flow guide assembly 120, and increases the contact area between the target medium and the heat absorption assembly 110, thereby improving the heat exchange efficiency of the heat collection system 100.

[0058] The regulating component 130 is used to regulate the working state of the heat absorption component 110 and / or the flow guiding component 120.

[0059] It should be noted that the working state of the heat absorption component 110 may include: the tilt angle of the heat absorption component 100 to the ground. The working state of the flow guide component 120 may include: the conduction state, tilt state, etc. of the flow guide component 120.

[0060] For example, the inclination angle between the heat absorption component 110 and the ground can be adjusted according to the user's actual usage needs or usage scenarios to adjust the effective area of ​​the heat absorption component 100 receiving solar radiation energy, thereby regulating the heat exchange efficiency between the target medium and the heat absorption component 110, and further regulating the working efficiency of the heat collection system 100.

[0061] For example, the conduction state, tilt state, etc. of the guide component 120 can be adjusted according to the user's actual usage needs or usage scenarios, so as to achieve the control of the flow speed of the target medium in the guide component 120 and the flow path of the target medium in the guide component 120 according to the user's actual usage needs or usage scenarios, so as to further improve the matching of the flow state of the target medium in the guide component 120 with the user's actual usage needs and usage scenarios, thereby improving the matching of the solar collection system 100 with the user's actual needs and actual usage scenarios.

[0062] Based on this, the present application provides a heat collection system 100, comprising: a heat absorbing assembly 110 for absorbing solar energy and converting it into thermal energy; a flow guide assembly 120 connected to the heat absorbing assembly 110 for conveying a target medium so as to exchange heat between the target medium and the heat absorbing assembly 110; wherein the flow guide assembly 120 comprises: a plurality of direct current assemblies 121 and a plurality of baffle assemblies 122, wherein the baffle assemblies 122 are arranged between the direct current assemblies 121 so as to form a serpentine shape; and a control assembly 130 for controlling the operating state of the heat absorbing assembly 110 and / or the flow guide assembly 120. The present application facilitates multi-level control of the operating state of the heat absorbing assembly 110 and / or the flow guide assembly 120 according to the actual user's usage needs and actual usage scenarios, thereby adjusting the flow path of the target medium in the flow guide assembly 120 and / or adjusting the effective area of ​​the heat absorbing assembly 110 absorbing solar radiation, thereby improving the matching of the operating state of the heat collection system 100 with the user's usage scenarios and needs, and enhancing the user experience.

[0063] In some feasible embodiments, the above-mentioned system 100 also includes: a sensing component 140, which is arranged on the heat absorption component 110 and is used to detect the position information of the sun; a driving component 150, including: a first driving component 151, which is arranged on the heat absorption component 110; and a regulating component 130 including: a first controller 131, which is connected to the first driving component 151 and is used to regulate the inclination angle of the heat absorption component 110 to a target inclination angle according to the position information.

[0064] For example, based on the position information of the sun detected by the sensor assembly 140 , the first controller 131 can determine in real time the effective area of ​​the heat absorption assembly 110 that can be used to receive solar radiation energy.

[0065] For example, if the first controller 131 determines that the effective area is less than a preset effective area threshold, the first controller 131 may control the tilt angle of the heat sink 110 to a target tilt angle via the first drive assembly 151, such that the effective area is greater than or equal to the preset effective area threshold. The preset effective area threshold can be set based on actual needs and is not specifically limited herein.

[0066] It should be noted that the above-mentioned control component 130 can also be used to control the tilt angle of the heat absorption component 110 to a target tilt angle according to the geographical latitude information of the target area, the current season information, the month information, etc.

[0067] Specifically, the target tilt angle may be approximately equal to the geographical latitude of the target area.

[0068] Specifically, the target tilt angle may also be determined based on the following formula according to the current month information and the geographical latitude information of the target area:

[0069] θopt=θlat+15°×sin(5MonthNumber-7) (1)

[0070] Among them, θopt is the target tilt angle, θlat is the geographical latitude of the target area, and Month Number is the current month.

[0071] Based on this, the above-mentioned system 100 can accurately control the inclination angle of the heat absorption component 110 to the target inclination angle according to the position information of the sun by configuring the above-mentioned sensor component 140, the drive component 150 and the first controller 131, so as to increase the effective area of ​​the heat absorption component 110 that can be used to receive solar radiation energy, thereby improving the heat absorption efficiency of the heat absorption component 110, improving the heat exchange efficiency between the target medium and the heat absorption component 110, and thus improving the heat collection efficiency of the heat collection system 100.

[0072] In some feasible embodiments, the above-mentioned driving component 150 also includes: a second driving component 152, which is arranged on the DC component 121 and the deflection component 122; the regulating component 130 also includes: a second controller 132, which is connected to the second driving component 152 to regulate the tilt state of the DC component 121 and the deflection component 122 to a target tilt state.

[0073] Exemplarily, the system 100 may also be configured with a control panel to facilitate the user to input target instructions to pre-set the target temperature of the target medium and the time point when the target medium reaches the target temperature.

[0074] Specifically, the second controller 132 can accurately calculate the target inclination of the DC component 121 and the baffle component 122 according to the target temperature and the time node, thereby adjusting the inclination of the DC component 121 and the baffle component 122 to the target inclination.

[0075] Based on this, the above-mentioned system 100, by configuring the second drive component 152 and the second controller 132, is conducive to improving the matching of the tilt state of the DC component 121 and the deflection component 122 with user needs, so that the flow path and flow time of the target medium in the serpentine guide channel match the target temperature and time node set by the user, thereby improving the user experience.

[0076] In some feasible embodiments, the above-mentioned DC component 121 includes: a first DC component 1211 and a second DC component 1212; the target state includes: the angle between the inclination direction of the first DC component 1211 and the horizontal direction is greater than 0 degrees and less than 90 degrees; the angle between the inclination direction of the second DC component 1212 and the horizontal direction is greater than -90° and less than 0°; wherein, the first DC component 1211 and the second DC component 1212 are alternately arranged; the deflector component 122 is arranged between the first DC component 1211 and the second DC component 1212; the inclination direction of the deflector component 122 corresponds to the inclination direction of the first DC component 1211 and the inclination direction of the second DC component 1212, so that the first DC component 1211 and the second DC component 1212 are interconnected, and the diversion channel is serpentine.

[0077] It should be noted that if Figure 3 As shown, based on the above-mentioned configuration, on the one hand, the flow path of the target medium from the inlet end a to the outlet end b within the serpentine channel can be extended, which is beneficial to increasing the contact time and contact area of ​​the target medium with the heat absorption component 110 in the flow guide component 120, thereby improving the heat exchange efficiency between the target medium and the heat absorption component 110, and further improving the heat collection efficiency of the heat collection system 100. On the other hand, by setting the inclination direction of the deflection component 122 to correspond to the inclination direction of the first DC component 1211 and the inclination direction of the second DC component 1212, when the target medium flows from the first DC component 1211, passes through the deflection component 122, changes its flow direction, and enters the second DC component 1212, the probability of turbulence generated when the target medium flows through the deflection component 122 and enters the second DC component 1212 is reduced, the flow resistance of the target medium is reduced, and the smoothness of the flow of the target medium is improved to avoid the occurrence of dead zones or uneven flow rates in the flow process of the target medium, which is beneficial to improving the operational smoothness and operational safety of the heat collection system 100 of the present application.

[0078] In some feasible embodiments, the above-mentioned guide component 120 is provided with multiple valve bodies, and the control component 130 also includes: a third controller 133, which is connected to the multiple valve bodies and is used to control the opening and closing degrees of the multiple valve bodies to control the flow speed of the target medium to the target flow speed.

[0079] For example, the plurality of valve bodies may be solenoid valves. Specifically, the plurality of valve bodies may be provided at the inlet end a, the outlet end b, the DC component 121 end, and the baffle component 122 end of the flow guide component 120.

[0080] Exemplarily, the third controller 133 may determine the target flow rate based on the target temperature of the target medium pre-set by the user through the control panel and the time point when the target medium reaches the target temperature, and then adjust the opening and closing degrees of the multiple valve bodies accordingly according to the target flow rate to adjust the flow rate of the target medium inside the guide assembly 120 to the target flow rate.

[0081] Specifically, when the target temperature input by the user through controlling the above-mentioned control panel is 60°C, and the time node at which the user hopes that the target medium will reach the above-mentioned target temperature of 60°C is 4:00 pm, and the third controller 133 calculates that the target flow velocity is 0.5 m / s, the third controller 133 can correspondingly adjust the opening and closing degrees of the above-mentioned multiple valve bodies so that the flow velocity of the target medium is changed to 0.5 m / s.

[0082] Alternatively, the user may manually set a target flow velocity of the target medium via the control panel. Specifically, if the target flow velocity manually set by the user via the control panel is 0.5 m / s, the third controller 133 may directly control the opening and closing degrees of the multiple valve bodies to change the flow velocity of the target medium within the flow guide assembly 120 to 0.5 m / s.

[0083] Based on this, the above-mentioned system 100 can improve the matching degree between the flow velocity of the target medium and the target temperature set by the user and the time node when the target medium reaches the above-mentioned target temperature by providing multiple valve bodies in the guide component 120 and configuring the third controller 133, thereby improving the matching degree between the flow state of the target medium and the actual use needs and actual use scenarios of the user, and further realizing multi-level regulation of the operating state of the solar collection system 100, thereby further improving the user experience.

[0084] It should be noted that in the event of a failure in the above-mentioned system 100, the above-mentioned third controller 133 is also used to emergency close all valve bodies to prevent the target medium from continuing to flow into the above-mentioned guide assembly 120 when a failure occurs in the above-mentioned solar collection system 100, causing secondary damage to the above-mentioned solar collection system 100. Based on this, by providing multiple valve bodies in the guide assembly 120 and configuring the third controller 133, it is beneficial to improve the operational safety of the solar collection system 100.

[0085] In some feasible embodiments, the above system also includes: a temperature sensing component 160, including: a first temperature sensing component 161, arranged at the outlet end b of the guide component 120, for detecting the first temperature of the target medium; a second controller 132, also used to correct the target tilt state according to the difference between the target temperature and the first temperature of the target medium.

[0086] It should be noted that the first temperature is the real-time temperature of the target medium flowing out of the guide assembly 120.

[0087] Exemplarily, the first temperature sensing component 161 may include a temperature sensor. Specifically, the temperature sensor may be disposed at the outlet end b of the flow guiding component 120 to detect the real-time temperature of the target medium flowing out of the flow guiding component 120 .

[0088] For example, if the absolute value of the difference between the target temperature of the target medium and the real-time temperature of the target medium upon exiting the flow guide assembly 120 is greater than a preset difference, the second controller 132 can adjust the target tilt state of the DC assembly 121 and the baffle assembly 122 by regulating the second drive assembly 152. The preset difference can be set based on the user's desired temperature accuracy for the target medium. The preset difference is negatively correlated with the user's desired temperature accuracy for the target medium; that is, the higher the user's desired temperature accuracy for the target medium, the smaller the preset difference.

[0089] Specifically, when the absolute value of the difference between the target temperature of the target medium and the real-time temperature is greater than the preset difference, and the real-time temperature is lower than the target temperature, the second controller 132 controls the inclination of the DC component 121 to increase, and adjusts the inclination of the deflection component 122 accordingly according to the inclination of the DC component 121, so as to increase the residence time of the target medium in the guide component 120, reduce the contact area between the target medium and the heat absorption component 110, and reduce the difference between the target temperature of the target medium and the first temperature to be less than the preset difference.

[0090] Specifically, when the absolute value of the difference between the target temperature of the target medium and the real-time temperature is greater than the preset difference, and the real-time temperature is higher than the target temperature, the second controller 132 controls the inclination of the DC component 121 to decrease, and adjusts the inclination of the deflection component 122 accordingly according to the inclination of the DC component 121, so as to reduce the residence time of the target medium in the guide component 120 and reduce the contact area between the target medium and the heat absorption component 110, so as to reduce the difference between the target temperature of the target medium and the first temperature to be less than the preset difference.

[0091] Based on this, the above-mentioned system 100 sets a first temperature sensing component 161 at the outlet end b of the guide component 120, which is conducive to accurately correcting the inclination state of the DC component 121 and the deflection component 122 according to the difference between the real-time temperature and the target temperature of the target medium at the outlet end b, and then correcting the flow state of the target medium in the guide component 120, thereby reducing the difference between the real-time temperature and the target temperature of the target medium at the outlet end b of the guide component 120, so as to improve the collection operation accuracy of the thermal collection system 100.

[0092] In some feasible embodiments, the temperature sensing component 160 further includes: a second temperature sensing component 162, which is arranged at the heat absorption component 110 and is used to detect the real-time temperature of the heat absorption component 110; a third temperature sensing component 163, which is arranged at the inlet end a of the flow guide component 120 and is used to detect the second temperature of the target medium; and a third controller 133, which is further used to adjust the opening and closing degree of multiple valve bodies according to the real-time temperature, the target temperature and the second temperature, so as to control the flow velocity of the target medium to the target flow velocity.

[0093] It should be noted that the second temperature is the initial temperature of the target medium when it flows into the flow guiding component 120 from the inlet end a of the flow guiding component 120 .

[0094] For example, the third controller 133 may calculate the target flow velocity of the target medium based on the following formula according to the length of the flow guide assembly 120, the heat exchange coefficient between the target medium and the heat absorption assembly 110, the effective heat absorption area of ​​the heat absorption assembly 110, the real-time temperature of the heat absorption assembly 110, the second temperature, the target temperature, the mass flow rate of the target medium, and the specific heat capacity of the target medium:

[0095]

[0096] Wherein, v is the target flow velocity, L is the length of the flow guide component 120, h is the heat transfer coefficient between the target medium and the heat absorption component 110, A is the effective heat absorption area of ​​the heat absorption component 110, T s is the real-time temperature of the heat absorption component 110, T i is the second temperature, T f is the target temperature, m is the mass flow rate of the target medium, c p is the specific heat capacity of the target medium.

[0097] It should be noted that the length L of the flow guide component 120, the heat transfer coefficient h between the target medium and the heat absorption component 110, the mass flow rate m of the target medium and the specific heat capacity c of the target medium are p The heat transfer coefficient h of the heat absorbing component 110 can be determined according to the material of the heat absorbing component 110. The effective heat absorbing area A of the heat absorbing component 110 and the real-time temperature T of the heat absorbing component 110 can be input in advance. s , second temperature T i The target temperature T can be determined in real time. f Can be user input.

[0098] After the third controller 133 accurately determines the target flow rate according to the formula (2), it can correspondingly adjust the opening and closing degrees of the multiple valve bodies to the target opening and closing degrees so that the flow rate of the target medium reaches the target flow rate.

[0099] Based on this, the above-mentioned system 100 is configured with the second temperature sensing component 162 and the third temperature sensing component 163 to accurately determine the flow velocity of the target medium according to the real-time temperature of the heat absorption component 110, the second temperature of the target medium, that is, the initial temperature, and the target temperature of the target medium, thereby accurately regulating the opening and closing degrees of multiple valve bodies to achieve the flow velocity of the target medium in the above-mentioned guide component 120 to reach the above-mentioned target flow velocity, thereby improving the matching degree between the flow state of the target medium in the guide component 120 and the actual needs of the user, thereby improving the operation accuracy of the above-mentioned heat collection system 100 and further improving the user experience.

[0100] In some feasible embodiments, the above-mentioned system 100 also includes: a thermoelectric conversion component 170, one end of the thermoelectric conversion component 170 is connected to the heat absorption component 110, and the other end is connected to the control component 130, the sensor component 140, the drive component 150, and / or the temperature sensing component 160, which is used to convert the solar energy generated by the heat absorption component 110 into electrical energy to supply power to the control component 130, the sensor component 140, the drive component 150, and / or the temperature sensing component 160.

[0101] For example, the thermoelectric conversion component 170 may be made of thermoelectric materials, such as bismuth telluride, lead telluride, etc. Specifically, the thermoelectric conversion component 170 may include a thermocouple, a thermopile, etc.

[0102] Based on this, the above-mentioned system 100 can convert the heat energy generated by the heat absorption component 110 into electrical energy by configuring the thermoelectric conversion component 170 to power the control component 130, the sensor component 140, the drive component 150, and / or the temperature sensing component 160, thereby reducing the dependence of the thermal collection system 100 on external power supply and improving the self-sufficiency of the thermal collection system 100.

[0103] In some feasible implementations, such as the heat collection system 100 described in any one of the above items, the pipe diameter of the flow guide component 120 decreases sequentially from the inflow direction of the target medium to the outflow direction of the target medium.

[0104] It should be noted that the above-mentioned inflow direction corresponds to the inlet end a of the flow guide component 120 , and the above-mentioned outflow direction corresponds to the outlet end b of the flow guide component 120 .

[0105] Specifically, the pipe diameter of the above-mentioned guide component 120 decreases sequentially along the direction from the inlet end a to the outlet end b.

[0106] Based on this, the above-mentioned system 100 limits the diameter of the conduit of the guide component 120 to decrease in sequence along the flow direction of the target medium, so that the target medium has a higher flow rate when entering the guide component 120. As the target medium gradually flows to the outlet end b of the guide component 120, the flow rate of the target medium gradually decreases, which is beneficial to increase the contact time between the target medium and the heat absorption component 110, further improve the heat exchange efficiency between the target medium and the heat absorption component 110, and thus further improve the heat collection efficiency of the heat collection system 100.
