[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the phase change material tube is embedded in the surface of the inner side mounting part under the cooperation of the external fan blade assembly, so that the phase change material can absorb heat at a specific temperature, and directly contact the high heat source point inside the reducer body through the heat spreader, so that the heat can be quickly and evenly conducted. Then, the heat conduction ring is installed on the top of the phase change material tube, and the bottom metal heat conduction plate frame is in contact with the top of the heat conduction ring to ensure that the heat can be quickly transferred to the ceramic heat sink. Under the joint action of the fixing part, the sealing flange and the bottom connection positioning block, the whole is ensured to be firmly installed in the connecting top groove. The fan frame is mounted on the fan blade frame, and a seal is formed to prevent dust and impurities from entering. Then the fan blade frame, the fan blade motor and the graphene composite fan blade group are combined to form an active heat dissipation structure. The heat is absorbed or blown out through the graphene composite fan blade group to accelerate the air flow and improve the heat dissipation efficiency. At the same time, under the action of the buckle edge, the buckle edge and the buckle groove can be buckled and connected, so that the ceramic heat sink is firmly located at the bottom of the graphene composite fan blade group. In certain high temperature environments, the temperature of the reducer can be reduced to avoid the reducer from being used for a long time. The efficiency of the reducer is affected by poor heat dissipation.

[0018] 2. In the present invention, heat is absorbed or discharged from the wind flow formed by the graphene composite fan blade group in the heat dissipation adjustment component and then through the heat dissipation adjustment port, the hot air is guided, and in cooperation with the micro-control processor, it is used to control the working state of the heat dissipation adjustment component, the external fan blade component, the condensation circulation component and the bottom heat dissipation fan blade component under the preset logic according to the temperature change monitored by the high-precision temperature sensor. Then, four groups of sleeves are equally installed around the side of the heat dissipation adjustment port to install the force-bearing telescopic column to ensure its operation stability. When the force-bearing telescopic column is operating, the micro-telescopic rod is controlled by the micro-control processor, so that when the micro-telescopic rod is driven to extend and retract under the action of electromagnetic or electric force, it drives the rotating plate to form a 0-60° rotation at the side of the force-bearing telescopic column, so that the force-bearing telescopic column receives the transmitted force, so that the force-bearing telescopic column rotates according to the angle in the sleeve, and then drives the elastic opening and closing piece to form elastic opening and closing inside the heat dissipation adjustment port, which can control the opening and closing degree of the heat dissipation adjustment port, realize dynamic adjustment of the heat dissipation efficiency, and facilitate the above The wind flow formed by the graphene composite fan blade group absorbs or discharges heat, and guides the gas to the upper space of the heat dissipation regulating port. That is, when the micro-control processor detects that the temperature rises, it will control the micro-telescopic rod to contract, thereby driving the force-bearing telescopic column to rotate in cooperation with the rotating plate, so that the elastic opening and closing piece opens a larger gap, increasing the flow area of ​​the heat dissipation regulating port, thereby accelerating the heat exchange rate and reducing the temperature. Conversely, when the temperature drops to a safe range, the micro-control processor will control the micro-telescopic rod to extend, reduce the opening of the elastic opening and closing piece, reduce air flow, and prevent excessive heat dissipation from causing the temperature to be too low. Then, under the action of the connecting rod, the whole is fastened to the surface of the top mounting ring plate. With the cooperation of the angle sensor, the opening and closing angle of the elastic opening and closing piece can be fed back according to the rotation angle of the force-bearing telescopic column. With the cooperation of the external back-blowing structure, it is convenient to install at the bottom of the graphene composite fan blade group and the ceramic heat sink. Then, when the graphene composite fan blade group and the surface of the ceramic heat sink are disturbed by dust, the dust and impurities on the heat dissipation path can be cleaned to ensure the heat dissipation efficiency.

[0019] 3. In the present invention, the circulating guide cooling tube is used to transmit and cool the medium in the circulation under the cooperation of the condensation circulation component, so that the top side end is connected to the condenser evaporator, so as to facilitate the transportation of the condensed gas generated by the condenser evaporator to the filter membrane pipe to realize the initial heat exchange, and the top of the condenser evaporator receives the condensing medium from the condensing medium gas transmission pipe, and the bottom is connected to the circulating guide cooling tube, which is used to evaporate the condensing medium to absorb heat and release cold energy during the condensation process, and with the cooperation of the semi-permeable membrane structure for removing moisture, it is used to remove moisture in the condensed gas released in the condenser evaporator and transport it to the circulating guide cooling tube, and the condensing medium gas transmission pipe and the refrigerant metering injection end are connected by a heat pipe, and the heat pipe technology is used to efficiently transfer heat, so that the working medium inside the heat pipe absorbs heat at the evaporation end and releases heat at the condensation end, and then the regulated gas is transported to the cooling tube. The condensable medium is in the gas transmission pipe, and when the heat dissipation gas is discharged and guided to the upper space of the heat dissipation regulating port, the micro heat pump is embedded in the dust storage chamber, and a small amount of electric energy is used to absorb heat from the low-temperature gas and transfer it to the refrigerant metering injection end through the pneumatic expansion valve tube, thereby improving the energy efficiency ratio of the entire system, and the pneumatic expansion valve tube can adjust the flow rate and pressure of the refrigerant, optimize the refrigeration efficiency, so that the refrigerant metering injection end controls the flow rate of the refrigerant into the system according to the energy efficiency heat transmitted, thereby ensuring the overall stable operation, and when the above-mentioned external back-blowing structure back-blows to dust, it is transported to the dust removal valve tube through the micro heat pump and the pneumatic expansion valve tube, and the control opening and closing in the dust removal valve tube is used to make the gas carrying dust guided to the inside of the dust storage chamber with the cooperation of the built-in filter net, so as to prevent the dust from following the gas flow trajectory into the reducer body and affecting the operation of the reducer body.

[0020] 4. In the present invention, by cooperating with the bottom heat dissipation fan blade assembly, when the dry condensed gas is transported to the filter membrane pipe, the motor can be controlled by the microcontroller to synchronously adjust the rotation angle of the air guide regulating valve plate according to the opening and closing degree of the elastic opening and closing piece, and adjust the wind direction and air volume according to the heat dissipation effect optimized according to actual needs, wherein the high-precision temperature sensor monitors the temperature of the key parts inside the reducer body, so that the microcontroller automatically adjusts the start-up regulation of the motor and the fan motor according to these data, so that with the cooperation of the notch, the air guide regulating valve plate can form a guide opening and closing inside the notch, so as to guide the condensed gas to the aluminum alloy fan blade group, so that the aluminum alloy fan blade group can transfer the condensed gas to the reducer. The heat source points inside the machine body are condensed and transported to take away the heat, and in actual operation, the overall process structure can form a cycle, that is, the built-in high-precision temperature sensor continuously monitors the temperature changes in key areas, so that the microcontroller analyzes the data and intelligently decides when to switch the working modes of the graphene composite fan blade group and the aluminum alloy fan blade group. As the heat load of the reducer body changes or the heat dissipation requirements are different, the roles of the two fan blade groups can be dynamically switched to meet the operating requirements of the graphene composite fan blade group absorbing heat and the aluminum alloy fan blade group conducting cooling, or the aluminum alloy fan blade group absorbing heat and the graphene composite fan blade group conducting cooling, and can adaptively adjust under different heat load conditions to ensure a continuous and stable heat dissipation effect.

The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the high-precision temperature sensor, condenser evaporator 32, refrigerant metering injection port 36, micro heat pump 39, micro control processor 43, phase change material tube 52, fan motor 593 and motor 65 will no longer be explained in detail.

[0044] The method of use and working principle of the device are as follows: first, the external fan blade assembly 5 is connected and installed through the top of the connecting top slot frame and the reducer body 1, and then the bottom heat dissipation fan blade assembly 6 is installed inside the installation slot 2, and the heat dissipation adjustment assembly 4 and the condensation circulation assembly 3 are used to make the external fan blade assembly 5 and the bottom heat dissipation fan blade assembly 6 form a circulation connection, that is, the inner side mounting member 51 is installed on the inner top side of the connecting top slot frame to form a basic connection fixing point, and then the phase change material tube 52 is embedded in the surface of the inner side mounting member 51, so that the phase change material can absorb heat at a specific temperature, and directly contact the high heat source point inside the reducer body 1 through the heat spreader 53, so that the heat can be quickly and evenly conducted, and then the heat conductive ring 54 is installed on the top of the phase change material tube 52. The bottom metal heat conducting plate frame 58 is in contact with the top of the heat conducting ring 54 to ensure that the heat can be quickly transferred to the ceramic heat sink 59. Under the joint action of the fixing part 57, the sealing flange 56 and the bottom connection positioning block 55, the whole is firmly installed on the connecting top groove frame and forms a seal to prevent dust and impurities from entering. Then the fan blade frame 591, the fan motor 593 and the graphene composite fan blade group 595 form an active heat dissipation structure, and the heat is absorbed or blown out through the graphene composite fan blade group 595 to accelerate the air flow and improve the heat dissipation efficiency. At the same time, under the action of the buckle edge 592, the buckle edge 592 and the buckle groove 590 can be buckled and connected, so that the ceramic heat sink 59 is firmly located at the bottom of the graphene composite fan blade group 595. Secondly, The heat dissipation regulating port 41 is used to absorb or discharge heat from the wind flow formed by the graphene composite fan blade group 595, guide the hot air, and in cooperation with the microcontroller 43, is used to control the working states of the heat dissipation regulating component 4, the external fan blade component 5, the condensation circulation component 3 and the bottom heat dissipation fan blade component 6 under a preset logic according to the temperature changes monitored by the high-precision temperature sensor. Then, four groups of sleeves 44 are equally installed around the side of the heat dissipation regulating port 41 to install the stressed telescopic column 47 to ensure its operational stability. When the stressed telescopic column 47 is operating, the micro-telescopic rod 49 is controlled by the micro-controller 43, so that when the micro-telescopic rod 49 is driven to retract under electromagnetic or electric action, it drives the rotating plate 45 to the side of the stressed telescopic column 47. The force-bearing telescopic column 47 is rotated at an angle of 0-60°, so that the force-bearing telescopic column 47 receives the transmitted force, so that the force-bearing telescopic column 47 is rotated in the sleeve 44 according to the angle, and then the elastic opening and closing piece 48 is driven to form elastic opening and closing inside the heat dissipation regulating port 41, which can control the opening and closing degree of the heat dissipation regulating port 41, and realize dynamic adjustment of the heat dissipation efficiency, so as to facilitate the wind flow formed by the above-mentioned graphene composite fan blade group 595 to absorb or discharge heat, and guide the gas to the upper space of the heat dissipation regulating port 41, that is, when the micro-control processor 43 detects that the temperature rises, it will control the micro-telescopic rod 49 to contract, and then drive the force-bearing telescopic column 47 to rotate in cooperation with the rotating plate 45, so that the elastic opening and closing piece 48 opens a larger gap, thereby increasing the flow area of ​​the heat dissipation regulating port 41.Thereby, the heat exchange rate is accelerated and the temperature is reduced. Conversely, when the temperature drops to a safe range, the microcontroller 43 controls the extension of the micro telescopic rod 49, reduces the opening of the elastic opening and closing piece 48, reduces air flow, and prevents excessive heat dissipation from causing the temperature to be too low. Then, under the action of the connecting rod 490, the whole is fastened to the surface of the top mounting ring plate 46. With the cooperation of the angle sensor 491, the opening and closing angle of the elastic opening and closing piece 48 can be fed back according to the rotation angle of the force-bearing telescopic column 47. With the cooperation of the external back-blowing structure, it is convenient to install it at the bottom of the graphene composite fan blade group 595 and the ceramic heat sink 59. When the surface of the graphene composite fan blade group 595 and the ceramic heat sink 59 is disturbed by dust, the dust and debris on the heat dissipation path can be cleaned. The heat dissipation efficiency is ensured, and the circulating guide cooling tube 31 cooperates with the circulating guide cooling tube 31 to transmit and cool the circulating medium, so that the top side end is connected to the condenser evaporator 32, so that the condensed gas generated by the condenser evaporator 32 is conveniently transported to the filter membrane pipe 64 to achieve the initial heat exchange, and the top of the condenser evaporator 32 receives the condensed medium from the condensing medium gas pipeline 34, and the bottom is connected to the circulating guide cooling tube 31, which is used to evaporate the condensed medium to absorb heat and release cold in the condensation process, and in cooperation with the semi-permeable membrane structure for removing moisture, it is used to remove moisture from the condensed gas released from the condenser evaporator 32 and transport it to the circulating guide cooling tube 31, and the heat pipe 35 is used to connect the condensing medium gas pipeline 34 and the refrigerant metering injection end 36, so as to achieve the initial heat exchange. Heat pipe technology is used to efficiently transfer heat, so that the working medium inside the heat pipe 35 absorbs heat at the evaporation end and releases heat at the condensation end, and then the regulated gas is transported to the condensation medium gas pipe 34, and when the heat dissipation gas is discharged and guided to the upper space of the heat dissipation regulating port 41, the micro heat pump 39 is embedded in the dust storage chamber 390, and a small amount of electric energy is used to absorb heat from the low-temperature gas and transfer it to the refrigerant metering injection end 36 through the pneumatic expansion valve tube 38, thereby improving the energy efficiency ratio of the entire system, and the pneumatic expansion valve tube 38 can adjust the flow rate and pressure of the refrigerant, optimize the refrigeration efficiency, so that according to the energy efficiency heat transmitted, the refrigerant metering injection end 36 controls the flow rate of the refrigerant into the system to ensure the overall stable operation, and when the above-mentioned external back-blowing structure back-blown to the dust When the dust is discharged, it is transported to the dust removal valve pipe 37 through the micro heat pump 39 and the pneumatic expansion valve pipe 38. The dust removal valve pipe 37 is opened and closed by controlling the opening and closing of the dust removal valve pipe 37, so that the gas carrying dust is guided to the inside of the dust storage chamber 390 with the cooperation of the built-in filter screen to prevent the dust from following the gas flow trajectory into the reducer body 1 and affecting the operation of the reducer body 1. After that, the aluminum alloy fan blade group 62 is fixed by the bottom connecting arc frame 61, and is also tightly connected to the mounting groove 2 through a sealing sheet to ensure the stability and sealing of the component and prevent dust and other impurities from entering. The aluminum alloy fan blade group 62 is made of a lightweight aluminum alloy with good thermal conductivity, which is used to accelerate air flow and improve heat dissipation efficiency. The shape and number of the blades are optimized to balance wind output and noise control.The slot frame 63 is fastened to the side of the bottom connecting arc frame 61, and the filter membrane pipe 64 and the installation motor 65 are connected. When the dry condensed gas is delivered to the filter membrane pipe 64, the motor 65 can be controlled by the micro-control processor 43 to synchronously adjust the rotation angle of the air guide regulating valve plate 66 according to the opening and closing degree of the above-mentioned elastic opening and closing piece 48, so as to adjust the wind direction and air volume according to the heat dissipation effect optimized according to actual needs. The high-precision temperature sensor monitors the temperature of the key parts inside the reducer body 1, so that the micro-control processor 43 automatically adjusts the start-up adjustment of the motor 65 and the fan motor 593 according to these data, so that with the cooperation of the slot 67, the air guide regulating valve plate 66 can form a guided opening and closing inside the slot 67, so as to guide the condensed gas to the aluminum alloy fan blade group 62, so that the aluminum alloy fan blades Group 62 can condense and guide the condensed gas to the internal heat source point of the reducer body 1 to take away the heat. In actual operation, the overall process structure can form a cycle, that is, the built-in high-precision temperature sensor continuously monitors the temperature changes in key areas, so that the microcontroller 43 analyzes the data and intelligently decides when to switch the working mode of the graphene composite fan blade group 595 and the aluminum alloy fan blade group 62. As the heat load of the reducer body 1 changes or the heat dissipation requirements are different, the roles of the two fan blade groups can be dynamically switched to meet the operation requirements of the graphene composite fan blade group 595 absorbing heat and the aluminum alloy fan blade group 62 conducting cooling, or the aluminum alloy fan blade group 62 absorbing heat and the graphene composite fan blade group 595 conducting cooling. It can be adaptively adjusted under different heat load conditions to ensure a continuous and stable heat dissipation effect.
