Description

Technical Field

[0001] The utility model relates to the field of thermal energy power generation equipment, in particular to a pulsating heat pipe power generation device of waste heat from air conditioners. Background Art

[0002] Pulsating heat pipe is a kind of electronic device cooler with great potential. Compared with traditional heat pipe, its biggest feature is simple structure without core, arbitrary bending shape, large equivalent heat transfer coefficient and small volume. The diameter of pulsating heat pipe is very small (the inner diameter is generally 0.5-3mm). It is made of metal capillary tube bent into a serpentine structure. One end of the elbow is the heating section and the other end is the cooling section. In the middle, the insulation section can be arranged as needed. After the interior is evacuated into a vacuum, a part of the working liquid is injected. Under the action of surface tension, the working liquid forms liquid columns and gas plugs of different lengths in the tube. Because the diameter of the tube is small enough, the bubble column and liquid column in the tube are arranged at intervals and randomly distributed. In the heating section, the working fluid absorbs heat to generate bubbles, which expand and increase pressure rapidly, pushing the working fluid to the cooling section. In the cooling section, the bubbles are cooled and broken, and the pressure drops. Due to the pressure difference between the two ends and the pressure imbalance between adjacent tubes, the working fluid oscillates and flows between the heating section and the cooling section, thereby realizing heat transfer.

[0003] Compared with the good thermal conductivity of pulsating heat pipes, structures that use pulsating heat pipes to generate electricity are rare. Therefore, how to provide a pulsating heat pipe power generation device for air-conditioning waste heat and use pulsating heat pipes to reuse air-conditioning waste heat has become a difficult problem that needs to be solved urgently by technical personnel in this field.

[0024] The insulating section of the pulsating heat pipe 4 is located inside the power generation chamber 1, the cooling section of the pulsating heat pipe 4 is located inside the cooling chamber 2, and the heating section of the pulsating heat pipe 4 is located inside the heating chamber 3; specifically, the heat discharged by the heat exchanger in the air-conditioning outdoor unit passes through the outer wall of the air-conditioning outdoor unit and the side wall of the heating chamber 3 by heat transfer and is absorbed by the heating section of the pulsating heat pipe 4.

[0025] Specifically, a rotating shaft 101 is disposed inside the power generation chamber 1, one end of the rotating shaft 101 is rotatably connected to the center of the front inner wall of the power generation chamber 1, and the other end passes through the rear wall of the power generation chamber 1 and extends to the outside of the power generation chamber 1;

[0026] Two rotating disks 102 are installed on the rotating shaft 101, and a plurality of permanent magnets 103 are irregularly installed on the two rotating disks 102. The two rotating disks 102 are respectively located at the front and rear sides of the pulsating heat pipe 4, and are both located inside the power generation chamber 1; a plurality of conductive coils 104 are arranged between the two rotating disks 102, and the two ends of the conductive coils 104 are connected to the storage battery 105, and the storage battery 105 is installed on the bottom wall of the power generation chamber 1;

[0027] The end of the rotating shaft 101 is connected to a windshield plate 107 via a connecting rod 106 .

[0028] Specifically, an air inlet 201 is opened on the side wall of the cooling chamber 2 , and an air outlet pipe 202 is installed on the top of the cooling chamber 2 . The hot air discharged from the air outlet pipe 202 is blown toward the wind shield 107 .

[0029] Specifically, a plurality of connecting rods 106 are provided and are evenly distributed around a circle, and an arc-shaped wind shield 107 is installed at the end of each connecting rod 106 .

[0030] In a specific implementation, the pulsating heat pipe power generation device of the air-conditioning waste heat can also be installed inside the air-conditioning outdoor unit, and the heating chamber 3 and the heat exchanger of the air-conditioning outdoor unit are placed in the same water area. The heat emitted by the heat exchanger of the air-conditioning outdoor unit is transferred to the heating chamber 3 through the same water area and absorbed by the heating section of the pulsating heat pipe 4.

[0031] Specifically, Figure 3 As shown, the inner cavity of the heating chamber 3 is connected to the inner cavity of the air conditioner outdoor unit through an air guide pipe 301, one end of the air guide pipe 301 is connected to the side wall of the heating chamber 3, and the other end is connected to the exhaust port of the air conditioner outdoor unit;
