[0015] Preferably, a baffle frame is fitted to the outer wall of the partition, and the outer wall of the baffle frame is fixed to the inner wall of the air inlet pipe.

[0016] Working principle: During use, the power management module converts mains power to power each module. Command parameters are input and set via a terminal or touchscreen to the control module. The control module then controls the power management module to power the graphene heating element, operating at 200-400W. The generated heat is rapidly conducted through the heat-conducting plate and evenly radiated to the outside, achieving the heating function. During this process, the thermostat monitors the surface temperature of the heat-conducting plate in real time and transmits this data to the control module for processing and analysis, improving safety during use. This solves the problem of existing heating devices having high power consumption and uneven heat distribution, leading to high temperatures at the heat dissipation points and a risk of burns.

[0017] This invention provides a low-energy-consumption composite graphene heat sink. It has the following beneficial effects:

[0018] 1. This invention processes the mains power through a power management module to supply power to each module, and sets operating parameters through a touch screen or wireless module. It also achieves low-power, uniform heat dissipation and safe operation through the cooperation of graphene heating elements and heat-conducting plates. Furthermore, the cooperation of a thermostat and control module further improves safety, thereby solving the problem that existing heating devices have high power and uneven heat distribution, resulting in high temperatures at the heat dissipation points and a risk of burns.

[0019] 2. This invention utilizes the temperature characteristics of shape memory metal to ensure that when an abnormal temperature occurs, the sliding of the slider causes the electrode contact point one to contact the electrode contact rod, generating a current signal that is transmitted to the control module for processing and analysis. The control module then controls the cooling fan to start at the corresponding power, improving the exchange of air between the inside and outside of the radiator shell and increasing the heat outflow from the upper side of the radiator shell, thereby reducing heat transfer to the front side of the radiator shell. This reduces the risk of accidents while also improving heating efficiency.

[0020] 3. The present invention uses a control module to determine the position of the shielding based on electrode contact one and electrode contact rod, and controls the output end of motor one to drive it, so that the output end of the lead screw drives the heat insulation baffle to slide in the corresponding area, blocking the path of radiation from that position to the outside, avoiding safety risks, thereby further improving the safety of the radiator.

[0021] 4. In this invention, the control module detects that multiple trigger components on the front side of the radiator housing are triggered. The control module then controls the output of the motor to drive the partition to rotate upward. The cooling fan conducts the heat inside the radiator housing to the outdoor environment through the air inlet pipe, thereby reducing the operational risk of the radiator. At the same time, the system displays warnings on the touch screen or sends warning messages to the terminal via the wireless module, indicating equipment abnormalities or module damage, thereby helping to further improve the safety of the radiator.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 5 This invention provides a low-energy composite graphene radiator, including a radiator shell 1. The radiator shell 1 has an air outlet 2 and an air inlet 10 on its upper and lower sides, respectively. A radiation port 3 is provided on the front side of the radiator shell 1. A graphene heating element 11 is fixed to the inner wall of the radiator shell 1. A heat-conducting plate 12 is fixed to the outer wall of the graphene heating element 11. A temperature controller 17 and several heat dissipation fins 13 are fixed to the outer wall of the heat-conducting plate 12. A wireless module 6, a power management module 15, and a control module 16 are installed on the inner wall of the radiator shell 1. A touch screen 7 is fixed to the front side of the radiator shell 1. A heat dissipation assembly 5 is provided on the inner top wall of the radiator shell 1, and the heat dissipation assembly 5 includes a cooling fan 53 fixed to the inner top wall of the radiator shell 1.

[0033] In this embodiment, the graphene heating element 11 is fixed to the rear inner wall of the radiator housing 1 by an array of spring screws. Each electronic control module is fixed to the inside of the radiator housing 1 by bolts. The touch screen 7 is detachably fixed to the front side of the radiator housing 1. The power management module 15 is electrically connected to the graphene heating element 11, the wireless module 6, the touch screen 7, the power management module 15, the control module 16, the temperature controller 17, and the cooling fan 53. The control module 16 is also electrically connected to the graphene heating element 11, the wireless module 6, the touch screen 7, the temperature controller 17, and the cooling fan 53. The power management module 15 includes a circuit management chip and a circuit management circuit, which is used to convert the power supply to the mains power supply. The circuit is converted to low-voltage DC power of 24V or 36V and includes overvoltage, overcurrent protection and fuse functions. The control module 16 can use a chip, microprocessor or microcontroller. The wireless module 6 includes one or more of Bluetooth, 2.4G and 4G wireless modules. The graphene heating element 11 is a high-polymer graphene conductive ink printed heating element with a conductive film on its outer wall. The heat sink shell 1 is made of galvanized steel plate. The heat conduction plate 12 is made of aerospace-grade 6063 aluminum alloy plate. The heat dissipation fins 13 are made of aluminum alloy 1050 and are welded to the front side of the heat conduction plate 12. All circuit modules are connected by high-temperature resistant wires. All of the above are existing technologies.

[0034] Specifically, during use, the radiator housing 1 is fixed to the indoor wall, the power is connected, and the mains power is converted by the power management module 15 to power each module. At this time, the touch screen 7 is turned on, and the mode and parameters are set through the touch screen 7. The touch screen 7 transmits the command signal to the control module 16 for processing and analysis. This radiator can also transmit commands and parameters to the control module 16 through the communication connection of external terminal devices and wireless module 6 to control the graphene heating element 11 to start heating. Through the material characteristics of the graphene heating element 11, the heat is efficiently converted, thereby enabling the radiator to achieve the effect of heating with low power operation.

[0035] Next, the heat generated by the graphene heating element 11 is conducted to the heat-conducting plate 12 through contact. Due to the material properties of the heat-conducting plate 12, the heat is quickly and evenly distributed and then radiated to the outside. At the same time, the fixed connection with the heat dissipation fins 13 increases the heat dissipation surface area of ​​the heat-conducting plate 12. Through the radiation conduction of the air, the heat is conducted to the outside through the radiation port 3, thereby achieving uniform heat distribution and avoiding dangerous situations caused by excessive local temperature.

[0036] During the operation of this radiator, cold air settles to the bottom of the space, while hot air rises to the top. Through the opening of the air outlet 2 and the air inlet 10, convection is formed in the vertical direction inside the radiator shell 1. Cold air enters the radiator shell 1 through the air inlet 10, is heated by the heat-conducting plate 12 and the heat dissipation fins 13, and is then discharged through the air outlet 2, further improving the heating efficiency of the radiator. The control module 16 can also control the radiator fan 53 to start, drawing air out of the radiator shell 1 and creating a negative pressure inside the radiator shell 1. This draws air into the radiator shell 1 through the air inlet 10, improving the efficiency of air convection inside the radiator shell 1 and thus improving the heating efficiency of the radiator.

[0037] During this process, the surface temperature of the heat-conducting plate 12 is monitored in real time by the thermostat 17 and transmitted to the control module 16 for processing and analysis. When the surface temperature of the heat-conducting plate 12 exceeds the preset value, the control module 16 controls the power management module 15 to disconnect the power supply to the graphene heating element 11 to prevent overheating from causing equipment damage or fire. When the temperature drops to the preset value, the control module 16 controls the power management module 15 to re-supply the graphene heating element 11 and resume heating. This achieves temperature control within a safe range, thereby solving the problem that existing heating equipment has high power and uneven heat distribution, resulting in high temperatures at the heat dissipation points and a risk of burns.

[0038] Please see the appendix Figure 1 Appendix Figure 7 and attached Figure 8Multiple trigger components 4 are provided on the front side of the heat sink housing 1. The trigger components 4 include a heat-conducting housing 40 fixed on the front side of the heat sink housing 1. A slider 43 is slidably connected to the inner wall of the heat-conducting housing 40. The slider 43 is composed of a horizontal part and a vertical part forming an L-shape. The upper end of the vertical part of the slider 43 is fixed to the lower side of one end of the horizontal part. The vertical part of the slider 43 is located inside the heat sink housing 1. The outer walls of the horizontal part of the slider 43 slide through the outer wall of the heat sink housing 1 and are slidably connected to the inner wall of the heat-conducting housing 40. A shape memory metal 42 is fixed between the side of the horizontal part of the slider 43 away from the heat-conducting plate 12 and the inner wall of the heat-conducting housing 40. An electrode contact 45 is fixed near the outer wall of the heat sink housing 1 on the vertical part of the slider 43. An electrode contact rod 46 is attached to the outer wall of the electrode contact 45. The electrode contact rod 46 is slidably connected to the inner wall of the heat sink housing 1.

[0039] Specifically, the shape memory metal 42 can be made of NiTi shape memory alloy. Its first state is a spring-extended shape at a temperature below 70 degrees Celsius, and its second state is a spring-contracted shape at a temperature above 85 degrees Celsius. These temperatures are set as a reference range. The electrode rod 46 and electrode contact 45 are electrically connected to the power management module 15 and the control module 16. The slider 43 is a horizontal L-shape. When the radiant outlet 3 on the radiator housing 1 is blocked by indoor furniture, there is a safety risk and a decrease in heating efficiency. Therefore, when the above situation occurs, the localized obstruction reduces the temperature in that area. As the temperature rises, the shape memory metal 42 contracts, causing the slider 43 to slide forward into the interior of the heat-conducting housing 40. The electrode contact 45 on the slider 43 contacts the electrode contact rod 46 on the inner wall of the radiator housing 1, and the generated current signal is transmitted to the control module 16 for processing and analysis. The control module 16 then controls the radiator fan 53 to start at the corresponding power, thereby increasing the exchange of air between the inside and outside of the radiator housing 1 and increasing the heat flow from the upper side of the radiator housing 1. This reduces the heat transfer to the front side of the radiator housing 1, thereby reducing the risk and improving heating efficiency.

[0040] Please see the appendix Figure 7 and attached Figure 8 A second spring 47 is fixed between the outer wall of the electrode contact rod 46 and the inner wall of the radiator housing 1, and a first spring 44 is provided between the vertical part of the slider 43 and the outer wall of the radiator housing 1 and the inner wall of the radiator housing 1.

[0041] Specifically, one end of spring 44 is fixed to the inner wall of the radiator housing 1, and the other end is in contact with the outer wall of the vertical part of slider 43. When the obstruction is removed or the local temperature drops to the point where the shape memory metal 42 returns to the first state, the shape memory metal 42 pushes the slider 43 to slide into the interior of the radiator housing 1, and the electrode contact 45 and the electrode contact rod 46 are no longer in contact. The control module 16 controls the cooling fan 53 to stop running. However, at this time, there is a situation where the push force of the shape memory metal 42 is insufficient or the reset is unstable. Through the setting of spring 44, when the shape memory metal 42 changes to the second state, the shape memory metal 42 contracts and drives the slider 43 to overcome the elastic potential energy of spring 47 and slide into the heat-conducting housing 40. So that when resetting, in addition to the shape memory metal 42 pushing the slider 43, spring 47 also provides an additional reset force for the slider 43, thereby realizing the stability of the reset of the slider 43.

[0042] Please see the appendix Figure 7 A heat insulation sleeve 41 is fixed between the outer walls of the heat-conducting housing 40 and the inner front wall of the radiator housing 1, and the outer walls of the slider 43 pass through the front side of the radiator housing 1.

[0043] Specifically, when heat is radiated to the outside through the radiation port 3, it will first be conducted to the front side of the heat sink housing 1, which may cause the heat-conducting housing 40 connected to the front side of the heat sink housing 1 to misjudge. Therefore, by setting the heat insulation sleeve 41, the heat of the heat sink housing 1 is isolated, avoiding conduction to the heat-conducting housing 40 and misjudgment, thereby helping to improve the accuracy of the triggering function of the triggering component 4.

[0044] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 5 A shielding assembly 9 is provided between the two side walls of the radiator housing 1. The shielding assembly 9 includes a lead screw 91 fixed between the two side walls of the radiator housing 1. A heat insulation baffle 93 is fixedly provided at the output end of the lead screw 91. The heat insulation baffle 93 is located between the front side of the heat dissipation fins 13 and the front inner wall of the radiator housing 1. A motor 90 is fixedly provided on the outer wall of the radiator housing 1. The output end of the motor 90 is fixedly provided on one side of the lead screw 91.

[0045] Specifically, the two ends of the lead screw 91 are fixed to the side walls between the left and right sides of the radiator housing 1, and are located between the front inner wall of the radiator housing 1 and the heat insulation baffle 93. It can drive the heat insulation baffle 93 to move left and right inside the radiator housing 1. The height of the heat insulation baffle 93 is the distance between the top and bottom two radiation ports 3, and can cover the height of the radiation ports 3. The motor 90, control module 16, and power management module 15 are all electrically connected. When the front side of the radiator housing 1 is blocked, causing the local temperature to rise, the control module 16 determines the position of the blockage based on the electrode contact 45 and the electrode contact rod 46, and controls the output end of the motor 90 to drive the output end of the lead screw 91 to drive the heat insulation baffle 93 to slide in the corresponding area, blocking the path of radiation to the outside from that position, avoiding safety risks, and thus further improving the safety of the radiator.

[0046] Please see the appendix Figure 3 and attached Figure 5 A guide rod 92 is fixed between the two sides of the radiator housing 1, and the outer wall of the guide rod 92 passes through the two sides of the heat insulation baffle 93.

[0047] Specifically, when the heat insulation baffle 93 slides left and right inside the radiator housing 1, the guide rod 92 provides support and guidance for the sliding of the heat insulation baffle 93, avoiding interference between the heat insulation baffle 93 and the other internal structures of the radiator housing 1, or the radiator housing 1 vibrating due to its own shaking, thereby helping to improve the stability of the radiator.

[0048] Please see the appendix Figure 4 and attached Figure 5 An electronic control housing 14 is fixed to the inner wall of the radiator housing 1. The power management module 15, the control module 16, and the wireless module 6 are all fixed to the inner wall of the electronic control housing 14.

[0049] Specifically, the control housing 14 has a heat insulation function and is detachably fixed to the inner wall of the radiator housing 1. Each control module is detachably fixed to the inner wall of the control housing 14 by bolts. By setting the control housing 14, the interior of the radiator housing 1 is divided into two areas, so that the power management module 15, the control module 16 and the wireless module 6 are inside the control housing 14 and are not affected by the high temperature inside the radiator housing 1. This avoids the impact of high temperature on the radiator control modules, thereby helping to improve the operational stability of the radiator.

[0050] Please see the appendix Figure 1 and attached Figure 4 The outer wall of the touch screen 7 is fixed with a heat insulation shell 8, and the outer wall of the heat insulation shell 8 passes through the front side of the heat sink shell 1.

[0051] Specifically, the heat insulation housing 8 has a heat insulation function, which enables the touch screen 7 to operate stably and avoids the radiation of high temperature inside the heat sink housing 1 from affecting its operating efficiency.

[0052] Please see the appendix Figure 4 Appendix Figure 5 and attached Figure 6 A heat dissipation pipe 51 is fixed to the inner top wall of the radiator housing 1. The outer wall of the cooling fan 53 is fixed to the inner wall of the heat dissipation pipe 51. An air inlet pipe 50 is fixed to the outer wall of the heat dissipation pipe 51. The outer wall of the air inlet pipe 50 passes through the rear side of the radiator housing 1. A partition 52 is rotatably connected to one side of the air inlet pipe 50. A second motor 54 is fixed to the inner wall of the electrical control housing 14. The output end of the second motor 54 is fixed to the outer wall of the partition 52.

[0053] Specifically, motor 54, control module 16, and power management module 15 are all electrically connected. If the front of the radiator housing 1 is largely covered and the thermostat 17 fails, the graphene heating element 11 will continue to generate heat and the temperature will exceed the preset safe temperature, posing a fire risk. At this time, control module 16 detects that multiple trigger components 4 on the front of the radiator housing 1 have been triggered. Control module 16 then controls the output of motor 54 to drive the partition 52 to rotate upward, closing the heat pipe 51 and opening the air inlet pipe 50. The cooling fan 53 conducts the heat inside the radiator housing 1 to the outdoor environment through the air inlet pipe 50 to reduce the operating risk of the radiator. At the same time, a warning is displayed on the touch screen 7 or a warning message is sent to the terminal via the wireless module 6 to indicate equipment abnormality or module damage, thereby helping to improve the safety of the radiator.

[0054] Please see the appendix Figure 6 A baffle 55 is attached to the outer wall of the partition 52, and the outer wall of the baffle 55 is fixed to the inner wall of the air inlet pipe 50.

[0055] Specifically, the air inlet duct 50 has a heat insulation function. Under normal conditions, the rear side of the partition 52 and the front side of the baffle 55 are sealed together by a sealing gasket to prevent cold outdoor air from entering the heat dissipation pipe 51. The partition 52 also has a heat insulation function to prevent heat from dissipating into the air inlet duct 50 when passing through the heat dissipation pipe 51, thereby avoiding heat loss of the radiator.

[0056] Workflow: When in use, fix the radiator housing 1 to the indoor wall, connect the power supply, and the power management module 15 converts the mains power to power each module. Set the operating parameters through the touch screen 7 or the wireless module 6. The control module 16 controls the graphene heating element 11 to start heating. Through the material characteristics of the graphene heating element 11, the heat is efficiently converted, thus enabling the radiator to achieve the effect of heating with low power operation.

[0057] Next, the heat generated by the graphene heating element 11 is conducted to the heat-conducting plate 12 through contact. Due to the material properties of the heat-conducting plate 12, the heat is quickly and evenly distributed and then radiated to the outside, thereby achieving uniform heat distribution and avoiding dangerous situations caused by excessive local temperature. Furthermore, the opening of the air outlet 2 and the air inlet 10 enables convection in the vertical direction inside the radiator shell 1, further improving the heating efficiency of the radiator.

[0058] During this process, the surface temperature of the heat-conducting plate 12 is monitored in real time by the thermostat 17 to improve the safety of the radiator operation. When there is a blockage on the front side of the radiator shell 1, the temperature state characteristics of the shape memory metal 42 cause the slider 43 to slide, causing the electrode contact 45 and the electrode contact rod 46 to contact. The generated current signal is transmitted to the control module 16 for processing and analysis. The control module 16 then controls the cooling fan 53 to start at the corresponding power, thereby reducing the danger and improving the heating efficiency. At the same time, the control module 16 controls the heat insulation baffle 93 to move to the blocking position to avoid safety risks.

[0059] If the control module 16 detects that multiple trigger components 4 on the front side of the radiator housing 1 have been triggered, the control module 16 controls the output of the motor 2 54 to drive the partition 52 to rotate upward. The cooling fan 53 conducts the heat inside the radiator housing 1 to the outdoor environment through the air inlet pipe 50 to reduce the operating risk of the radiator. At the same time, the control module 16 displays a warning on the touch screen 7 or sends a warning message to the terminal through the wireless module 6 to indicate equipment abnormality or module damage, thereby helping to further improve the safety of the radiator.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
