Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 6 The present invention provides a technical solution: an energy utilization device, comprising a shell 1 and a condenser 2, the inner wall of the shell 1 is provided with a temperature difference power generation component, the condenser 2 comprises a steam inlet end 3 and a water outlet end 4, and the inner wall of the shell 1 is fixedly connected with a support plate 5; Static heat dissipation fins 6 are fixedly connected to both sides of the surface of the condenser 2, and also include a blowing component for blowing air to dissipate heat on the surface of the condenser 2. Heat dissipation ports 7 for heat flow to pass through are provided on the upper end of the outer shell 1 and the surface of the support plate 5. The high-calorie steam discharged from the air-conditioning duct passes through the hot end heat exchanger of the temperature difference power generation component, enters the condenser 2 from the steam inlet end 3, and is initially cooled by the condenser 2 and the static heat dissipation fins 6. Under the coordinated heat dissipation of the blowing component and the dynamic heat dissipation component, the water vapor after heat dissipation and cooling flows out in the form of liquid water at the water outlet 4, and passes through the cold side heat exchanger of the temperature difference power generation component, so that the temperature difference power generation component generates electricity, thereby utilizing the steam heat and achieving energy-saving effects.

[0021] In order to improve the power generation efficiency of the temperature difference power generation component and improve the energy-saving effect of the device, further, the blowing component includes a fan 8, and the fan 8 is arranged directly below the static heat dissipation fins 6. It also includes a first driving component that drives the fan 8 to move horizontally left and right and prolongs the blowing time of the central area of ​​the condenser 2. The fan 8 moves synchronously to blow air to dissipate heat to the condenser 2 and the static heat dissipation fins 6. The hot air is discharged from the outer casing 1 through the heat dissipation port 7, thereby improving the heat dissipation effect of the condenser 2, and further making the temperature of the liquid water flowing out of the water outlet 4 lower, so that the temperature difference between cold and hot is increased, the power generation efficiency is improved, and the energy-saving effect is improved.

[0022] Furthermore, the first driving component includes a motor 9, the surface of the output shaft of the motor 9 is fixedly connected with a rotating shaft 10, the inner wall of the support plate 5 is fixedly connected to a reciprocating screw 30, the rotating shaft 10 and the surface of the reciprocating screw 30 are transmission connected through a belt connecting assembly, the end of the reciprocating screw 30 is fixedly connected to a rotating plate 12, the end of the rotating plate 12 is fixedly connected to a rotating column 13, the inner wall of the shell 1 is fixedly connected to a gear 14, the surface of the gear 14 is fixedly connected to a swing plate 15, the surface of the swing plate 15 is provided with a limiting groove 16, the surface of the rotating column 13 slides along the groove wall of the limiting groove 16, the surface of the gear 14 is meshed with a gear 2, the surface of the gear 2 17 is fixedly connected with a rotating shaft 3 18, the end of the rotating shaft 3 18 is fixedly connected to a plate body 19, the surface of the plate body 19 is provided with a slide groove 20, the inner wall of the slide groove 20 is slidably connected to a moving column 21, the inner wall of the shell 1 is fixed A guide rail 32 is connected, and a slider 22 is fixedly connected to the surface of the movable column 21. The surface of the slider 22 slides along the inner wall of the guide rail 32. A connecting plate 23 is fixedly connected to the surface of the slider 22. The surface of the connecting plate 23 is fixedly connected to the outer wall of the fan 8. During the circulation of water vapor in the condenser 2, the motor 9 is started, and the output shaft of the motor 9 rotates to drive the rotating shaft 10 to rotate, thereby driving the reciprocating screw 30 to rotate under the action of the belt connection component. The rotation process of the reciprocating screw 30 causes the rotating plate 12 to rotate, thereby driving the rotating column 13 to perform a circular motion along the groove wall of the limiting groove 16, thereby causing the swing plate 15 to swing. The swinging of the swing plate 15 drives the gear 14 to rotate alternately forward and reverse, thereby causing the gear 2 17 to rotate alternately forward and reverse, thereby causing the rotating shaft 3 18 to rotate synchronously. Through the positive and negative alternating rotation process of the rotating shaft 3 18, the plate body 19 is as Figure 4 The slider 22 is driven by the movable column 21 to move to the left along the inner wall of the guide rail 32, thereby driving the fan 8 to move synchronously. Figure 4 The speed of the rotating shaft 18 pushing the moving column 21 to move leftward also slows down accordingly. When the plate 19 swings to the vicinity of the reciprocating screw 30, the movement speed of the moving column 21 reaches the slowest. As the moving column 21 continues to move leftward away from the reciprocating screw 30, the speed of the moving column 21 increases accordingly. Since the condenser 2 is arranged in a coiled shape, the heat at the center of the condenser 2 is the most difficult to dissipate. Through the above process, the fan 8 can be moved left and right to blow air to dissipate heat to the condenser 2 and the static heat dissipation fins 6. The hot air is discharged from the housing 1 through the heat dissipation port 7. The closer the fan 8 is to the center of the condenser 2, the slower the movement speed is. This prolongs the heat dissipation time for the center of the condenser 2, making the heat dissipation effect of the condenser 2 better, thereby making the temperature of the liquid water flowing out of the water outlet 4 lower, increasing the temperature difference between hot and cold, improving the power generation efficiency, and improving the energy saving effect.

[0023] In order to further improve the heat dissipation effect of the condenser 2, the temperature difference between the steam inlet end 3 and the water outlet end 4 is increased, the energy saving effect is improved, and further, a dynamic heat dissipation component is included to accelerate the heat dissipation efficiency of the central area of ​​the condenser 2.

[0024] Furthermore, the dynamic heat dissipation component includes a movable fin 1 24 and a movable fin 25, the inner walls of the movable fin 1 24 and the movable fin 25 are slidably connected with a heat dissipation rod 26, the heat dissipation rod 26 is fixedly connected to the surface of the condenser 2, the surface of the movable fin 25 is fixedly connected with a gear 3 27 for fixed-axis rotation, the surface of the static heat dissipation fin 6 is fixedly connected with a gear row 1 28, the surface of the movable fin 25 is fixedly connected with a gear row 29, the surface of the gear 3 27 is respectively meshed with the surfaces of the gear row 1 28 and the gear row 2 29, the heat of the condenser 2 can be transferred through the heat dissipation rod 26, the movable fin 1 24 and the movable fin 2 25 in sequence, thereby increasing the heat dissipation area and improving the heat dissipation effect of the condenser 2.

[0025] In order to increase the heat dissipation efficiency of the dynamic heat dissipation component, reduce the temperature of the liquid water flowing out from the water outlet 4, and improve the power generation efficiency, further, it also includes a second driving component for driving the movable fin 1 24 and the movable fin 2 25 to move vertically.

[0026] Furthermore, the second driving component includes a reciprocating screw sleeve 31 disposed on the surface of the reciprocating screw 30, and the end of the reciprocating screw sleeve 31 is fixedly connected to the surface of the movable fin 24. When the fan 8 moves left and right to blow air to the condenser 2 and the static heat dissipation fin 6, as shown in FIG. Figure 2 In the state shown, the fan 8 blows toward the static heat dissipation fin 6, the movable fin 1 24 and the movable fin 2 25 at the same time, and the height difference between the static heat dissipation fin 6, the movable fin 1 24 and the movable fin 2 25 forms a concave shape. At this time, the airflow blown by the fan 8 can be concentrated from both sides to the center of the condenser 2 to improve the heat dissipation effect of the center of the condenser 2. As the fan 8 moves to the right Figure 3 In the state shown, the reciprocating screw 30 is rotated to make the reciprocating screw sleeve 31 move downward, driving the movable fin 1 24 to move downward along the surface of the heat dissipation rod 26, and through the cooperation of the tooth row 1 28 and the tooth row 29, the movable fin 25 is accelerated to move downward relative to the movable fin 1 24. When the fan 8 is far away, the surface area formed by the combination of the movable fin 25, the movable fin 1 24 and the heat dissipation rod 26 is increased, and the heat dissipation effect of the condenser 2 is improved. As the fan 8 continues to move toward the dynamic heat dissipation component, with the cooperation of the reciprocating screw 30 and the reciprocating screw sleeve 31, the movable fin 2 and the movable fin 1 24 move up again and return to the Figure 2In the state shown, by repeating the above process, the heat dissipation effect of the condenser 2 can be greatly improved, the temperature difference between the steam inlet end 3 and the water outlet end 4 can be increased, and the energy saving effect can be improved.

[0027] In order to increase the heat dissipation area and achieve a better cooling effect of the condenser 2, further, the number of dynamic heat dissipation components is two, and they are symmetrically arranged with the reciprocating screw 30 as the axis.

[0028] Working principle: When the energy utilization device is in use, the high-calorie steam discharged from the air-conditioning duct passes through the hot-end heat exchanger of the temperature difference power generation component, enters the condenser 2 from the steam inlet end 3, and is initially cooled by the condenser 2. The heat in the condenser 2 is quickly dissipated through the static heat dissipation fins 6 fixed on its surface. The water vapor after heat dissipation and cooling flows out in the form of liquid water at the water outlet end 4, and passes through the cold-side heat exchanger of the temperature difference power generation component, so that the temperature difference power generation component generates electricity, thereby utilizing the steam heat and achieving energy-saving effects.

[0029] During the circulation of the water vapor in the condenser 2, the motor 9 is started, and the output shaft of the motor 9 rotates to drive the rotating shaft 10 to rotate, thereby driving the reciprocating screw 30 to rotate under the action of the belt connection assembly. The rotation of the reciprocating screw 30 causes the rotating plate 12 to rotate, thereby driving the rotating column 13 to perform a circular motion along the groove wall of the limiting groove 16, thereby causing the swing plate 15 to swing, and the swing plate 15 swings to drive the gear 14 to rotate alternately forward and reverse, thereby causing the gear 2 17 to rotate alternately forward and reverse, thereby causing the rotating shaft 3 18 to rotate synchronously, and through the process of the rotating shaft 3 18 rotating alternately forward and reverse, the plate body 19 is as shown Figure 4 The slider 22 is driven by the movable column 21 to move to the left along the inner wall of the guide rail 32, thereby driving the fan 8 to move synchronously. Figure 4 The speed of the rotating shaft 18 pushing the moving column 21 to move leftward also slows down accordingly. When the plate 19 swings to the vicinity of the reciprocating screw 30, the movement speed of the moving column 21 reaches the slowest. As the moving column 21 continues to move leftward away from the reciprocating screw 30, the speed of the moving column 21 increases accordingly. Since the condenser 2 is arranged in a coiled shape, the heat at the center of the condenser 2 is the most difficult to dissipate. Through the above process, the fan 8 can be moved left and right to blow air to dissipate heat to the condenser 2 and the static heat dissipation fins 6. The hot air is discharged from the housing 1 through the heat dissipation port 7. The closer the fan 8 is to the center of the condenser 2, the slower the movement speed is. This prolongs the heat dissipation time for the center of the condenser 2, making the heat dissipation effect of the condenser 2 better, thereby making the temperature of the liquid water flowing out of the water outlet 4 lower, increasing the temperature difference between hot and cold, improving the power generation efficiency, and improving the energy saving effect.

[0030] In the process that the fan 8 moves left and right to blow air to the condenser tube 2 and the static heat dissipation fins 6 for heat dissipation, Figure 2 In the state shown, the fan 8 blows toward the static heat dissipation fin 6, the movable fin 1 24 and the movable fin 2 25 at the same time, and the height difference between the static heat dissipation fin 6, the movable fin 1 24 and the movable fin 2 25 forms a concave shape. At this time, the airflow blown by the fan 8 can be concentrated from both sides to the center of the condenser 2 to improve the heat dissipation effect of the center of the condenser 2. As the fan 8 moves to the right Figure 3 In the state shown, the reciprocating screw 30 is rotated to make the reciprocating screw sleeve 31 move downward, driving the movable fin 1 24 to move downward along the surface of the heat dissipation rod 26, and through the cooperation of the tooth row 1 28 and the tooth row 29, the movable fin 25 is accelerated to move downward relative to the movable fin 1 24. When the fan 8 is far away, the surface area formed by the combination of the movable fin 25, the movable fin 1 24 and the heat dissipation rod 26 is increased, and the heat dissipation effect of the condenser 2 is improved. As the fan 8 continues to move toward the dynamic heat dissipation component, with the cooperation of the reciprocating screw 30 and the reciprocating screw sleeve 31, the movable fin 2 and the movable fin 1 24 move up again and return to the Figure 2 In the state shown, by repeating the above process, the heat dissipation effect of the condenser 2 can be greatly improved, the temperature difference between the steam inlet end 3 and the water outlet end 4 can be increased, and the energy saving effect can be improved.
