Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation technology, and in particular to a wind-cooled heat dissipation device for ORC air-cooled low-temperature waste heat power generation. Background Technology
[0002] The organic Rankine cycle principle fully utilizes the energy-saving and high-speed characteristics of magnetic levitation generators. Industrial low-temperature waste heat liquid and waste heat flue gas are converted into high-pressure organic steam through heat exchange, thereby driving the magnetic levitation turbine generator to generate electricity. The cooling medium is mostly cooled by air.
[0003] A search revealed a prior art ORC (Organic Refrigerant Controller) cooling hot water circulation system (publication number: CN220648299U), which includes a flue gas hot water heat exchanger. The flue gas hot water heat exchanger is connected to an ORC low-temperature waste heat power generation device via a first pipe. The ORC low-temperature waste heat power generation device is connected to a hot water pressure stabilizing tank via a second pipe. The hot water pressure stabilizing tank is connected to the flue gas hot water heat exchanger via a third pipe. An automatic exhaust valve is installed on the first pipe, and a hot water circulation pump is installed on the third pipe. The first and second pipes are respectively connected to an air-cooled radiator via pipes. A tap water supply pipe and a drain pipe are respectively connected to the third pipe on the left side of the hot water circulation pump.
[0004] Existing technology uses two headers, one above the other, to transport the medium through Y-shaped pipes and combine it with flowing air for heat dissipation. The air flows from the front end of the pipes to the rear end. The actual contact area between the Y-shaped pipes and the cold air is very small, which limits the cooling effect. In addition, this type of pipe distribution will create projection obstruction, that is, the front pipe will block the airflow of the rear pipe.
[0005] Therefore, we propose an air-cooled heat dissipation device for ORC air-cooled low-temperature waste heat power generation. Utility Model Content
[0006] The present invention mainly addresses the technical problems of the aforementioned pipeline air collision and provides an air-cooled heat dissipation device for ORC air-cooled low-temperature waste heat power generation.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: an air-cooled heat dissipation device for ORC air-cooled low-temperature waste heat power generation, comprising: The two frames are symmetrically arranged. Each frame is fixedly equipped with an upper manifold and a lower manifold. The upper and lower manifolds are fixedly connected with several cross-shaped cooling pipes. The upper and lower manifolds at opposite corners are interconnected through the cooling pipes and transport the medium. An air guide structure is set between two frames to blow air to the cooling pipe for heat dissipation. The air guide structure includes side baffles and fins. Several fins are arranged between the two frames. The cooling pipe passes through the fins. A side baffle is fixedly installed on each of the opposite sides. Cold air can pass through the gaps between the multiple fins from bottom to top and cool the cooling pipe.
[0008] In a preferred embodiment of this utility model, both the upper and lower manifolds are fixedly connected to pipes. The cooling pipe communicates with the chamber of the lower manifold. One end of the cooling pipe is fixedly connected to the upper manifold, and the other end of the cooling pipe is fixedly connected to the lower manifold at a diagonal position. Two adjacent cooling pipes are distributed in an X-shape.
[0009] In a preferred embodiment of this utility model, the fin is a rectangular plate with a circular hole for the cooling pipe to pass through, and the cooling pipe is interference-fitted with the circular hole.
[0010] In a preferred embodiment of this utility model, the air guiding structure further includes an upper air collecting hood, a fan, and a lower air collecting hood. The upper air collecting hood is fixedly connected to the upper end of the fins, the fan is fixedly connected to the upper air collecting hood, and the lower air collecting hood is fixedly connected to the lower end of the fins.
[0011] In a preferred embodiment of this utility model, the upper gas collecting hood is a rectangular plate, the upper gas collecting hood is the same height as the fins, the upper gas collecting hood blocks and seals the gaps formed on the sides of multiple fins, and the fins are fixed to the upper gas collecting hood by welding.
[0012] In a preferred embodiment of this utility model, both the upper and lower gas collecting hoods are funnel-shaped structures, with the larger ports of the upper and lower gas collecting hoods fixedly connected to the fins, and the fan fixedly installed at the upper end of the upper gas collecting hood.
[0013] This invention provides an air-cooled heat dissipation device for ORC (Organic Refrigerant Controller) air-cooled low-temperature waste heat power generation. It has the following beneficial effects: 1. This air-cooled heat dissipation device for ORC air-cooled low-temperature waste heat power generation has an upper and lower header at the front end for feeding. The pipes can be connected through Y-shaped joints. The medium in the upper header is transported to the lower header at the opposite corner by the cooling pipes. Similarly, the medium in the lower header is transported to the upper header at the opposite corner by the corresponding cooling pipes. By transporting the medium through multiple cross-distributed cooling pipes, the air impact area and the flow of the medium can be increased, improving the heat dissipation effect and efficiency. With the help of multiple fins and the upper air collection hood, the air is guided to ensure that each cooling pipe is fully impacted by the air for cooling. Compared with the existing technology of stacked cooling pipes, the cooling pipes in this solution are staggered and do not block each other, resulting in better heat dissipation. Combined with the downward flow of air, it is more in line with the fluid characteristics of hot air rising.
[0014] 2. This air-cooled heat dissipation device for ORC air-cooled low-temperature waste heat power generation uses a fan to synchronously draw air from the gaps between multiple fins. The air enters from the lower air collection hood, carrying away the heat from multiple cooling pipes, and is then drawn away by the fan from the upper air collection hood. The airflow between the multiple fins is more uniform, ensuring that each cooling pipe is fully cooled and dissipated, avoiding local heat accumulation in the cooling pipes that causes turbulence in the medium due to temperature differences, and resulting in better uniformity of medium cooling.

[0017] An air-cooled heat dissipation device for ORC air-cooled low-temperature waste heat power generation, such as Figure 1 As shown, it includes: Two symmetrically arranged frames 10 are provided. Each frame 10 is fixedly equipped with an upper header 11 and a lower header 12. The upper header 11 and the lower header 12 are fixedly connected with several cross-distributed cooling pipes 13. The upper header 11 and the lower header 12 at diagonal positions are interconnected through the cooling pipes 13 and transport the medium. like Figure 1 , Figure 2 and Figure 3As shown, an air guide structure is installed between two frames 10 to blow air and dissipate heat from the cooling pipe 13. The air guide structure includes side baffles 20 and fins 24. Several fins 24 are arranged between the two frames 10, and the cooling pipe 13 passes through the fins 24. A side baffle 20 is fixedly installed on each opposite side. Cold air can pass through the gaps between the multiple fins 24 from bottom to top and cool the cooling pipe 13. Both the upper header 11 and the lower header 12 are fixedly connected to pipes. The cooling pipe 13 communicates with the chamber of the lower header 12. One end of the cooling pipe 13 is fixedly connected to the upper header 11, and the other end of the cooling pipe 13 is fixedly connected to the diagonally opposite position. The lower header 12 is fixedly connected, and two adjacent cooling pipes 13 are distributed in an X shape. The fins 24 are rectangular plates with circular holes for the cooling pipes 13 to pass through. The cooling pipes 13 are interference-fitted with the circular holes. The upper gas collection shroud 21 is a rectangular plate with the same height as the fins 24. The upper gas collection shroud 21 blocks and seals the gaps formed on the sides of multiple fins 24. The fins 24 are fixed to the upper gas collection shroud 21 by welding. The connecting pipe is connected to the interface of the circulating pump of the motor equipment through the pipe. The heat medium is sent into the cooling pipes 13 through the connecting pipe and then returned after being cooled by air cooling to achieve air cooling. In this design, the upper header 11 and lower header 12 at the front end are used for feeding. The connecting pipes can be collected through Y-shaped connectors. The medium in the upper header 11 is transported by the cooling pipe 13 to the lower header 12 at the opposite corner. Similarly, the medium in the lower header 12 at the front end is transported by the corresponding cooling pipe 13 to the upper header 11 at the opposite corner. By transporting the medium through multiple cross-distributed cooling pipes 13, the air impact area can be increased, the flow of the medium can be improved, and the heat dissipation effect and efficiency can be improved. With the help of multiple fins 24 and the upper air collection hood 21, the air is guided to ensure that each cooling pipe 13 is fully impacted by the air to cool down. Compared with the stacked cooling pipes 13 in the prior art, in this design, because the cooling pipes 13 are staggered, the cooling pipes 13 will not block each other, thus the heat dissipation effect is better. Combined with the downward flow of air, it is more in line with the fluid characteristics of hot air rising.
[0018] like Figure 4 As shown, the air guiding structure also includes an upper air collecting hood 21, a fan 22, and a lower air collecting hood 23. The upper air collecting hood 21 is fixedly connected to the upper end of the fin 24, the fan 22 is fixedly connected to the upper air collecting hood 21, and the lower air collecting hood 23 is fixedly connected to the lower end of the fin 24. Both the upper air collecting hood 21 and the lower air collecting hood 23 are funnel-shaped structures. The larger port of the upper air collecting hood 21 and the lower air collecting hood 23 is fixedly connected to the fin 24. The fan 22 is fixedly installed at the upper end of the upper air collecting hood 21. In this design, the fan 22 is a duct fan. The fan 22 synchronously draws air from the gaps between the multiple fins 24. The air enters from the lower air collection hood 23 below, carrying away the heat from the multiple cooling pipes 13, and is then drawn away by the fan 22 from the upper air collection hood 21. The airflow between the multiple fins 24 is more uniform, ensuring that each cooling pipe 13 is fully cooled and prevented from accumulating heat in localized cooling pipes 13, which could cause turbulence in the medium due to temperature differences. The cooling uniformity of the medium is better. The cooled medium flows out from the upper manifold 11 and the cooling pipes 13 at the back, and is collected and sent back into the circulation pipeline through another Y-shaped pipe.
[0019] The working principle of this utility model is as follows: The upper header 11 and lower header 12 at the front end are used for feeding. The connecting pipe can be collected through a Y-shaped connector. The medium in the upper header 11 is transported to the lower header 12 at the opposite position by the cooling pipe 13. Similarly, the medium in the lower header 12 at the front is transported to the upper header 11 at the opposite position by the corresponding cooling pipe 13. The medium is transported through multiple cross-distributed cooling pipes 13. The fan 22 synchronously draws air from the gaps between multiple fins 24. The air enters from the lower air collection hood 23 below and carries away the heat of multiple cooling pipes 13. After that, it is drawn away by the fan 22 from the upper air collection hood 21. The air flow at the gaps between multiple fins 24 is more uniform, ensuring that each cooling pipe 13 is fully cooled. The cooled medium flows out from the upper header 11 and cooling pipe 13 at the back and is collected and sent back to the circulation pipeline through another Y-shaped connecting pipe. The fan needs to be connected to a power supply and a control switch for use, which will not be described in detail here.
