Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to an integrated air-cooling heat exchanger. Background Art

[0002] An air-cooled heat exchanger is a heat exchange device that uses the wind from a blower as a cooling medium. The blower forces air across the outside of the finned tubes, cooling or condensing the high-temperature process gas or liquid inside the tubes. It is mainly composed of three basic parts: finned tubes, a blower, and a frame. Compared with water cooling, air cooling can save water resources and reduce industrial emissions. It is commonly used in industrial fields such as chemical, petrochemical, and thermal power plants.

[0003] In the prior art, Chinese patent publication number CN220103825U discloses an air-cooled heat exchanger, which includes a channel steel frame, a first bellows fixedly connected to one side of the top of the channel steel frame, one end of the first bellows fixedly connected to an inlet, an internal movably connected to a guide mechanism of the first bellows, a side of the channel steel frame away from the first bellows fixedly connected to a second bellows, one end of the second bellows fixedly connected to an outlet, a heat exchange mechanism is provided on the top of the channel steel frame, and group plates are fixedly connected to the left and right sides of the heat exchange mechanism. The utility model uses a guide mechanism to drive the first reversing plate and the second reversing plate to swing back and forth by a motor. Under the diversion of the diverter plate, the medium inside the first bellows can evenly enter the interior of each fin tube, thereby increasing the utilization rate of each fin tube in turn, reducing the burden on the fin tube in the center, and effectively improving the overall heat exchange efficiency.

[0004] The working principle of the above patent mentions that "when the threaded connection tube 703 inside the connection hole 704 is rotated, the fin tube 701 and the rubber sleeve 702 can be effectively separated, which facilitates the disassembly of the fin tube 701, and at the same time, the sliders 9 on both sides of the assembly plate 8 are plugged into the channel steel frame 1." However, the above structure only replaces the fin tube, and the fan of the hot and cold heat exchanger cannot be disassembled. There is no obstruction on the front side of the fan, so that the fan will absorb dust, dirt and other particulate matter in the air during operation, thereby causing dust and dirt to accumulate inside the fan, thereby affecting the operating efficiency and life of the fan. In response to the above problems, an integrated air-cooled heat exchanger is proposed to solve the above problems. Utility Model Content

[0042] When the user needs to control the air flow rate in the outlet pipe 12 of the pipe outlet connected to the external cold source and heat source to optimize the heat load processing capacity of the heat exchanger, the angle of the finger rod 16 on the adjustment block 13 fixed on the outside of the outlet pipe 12 at the bottom end of the cold source pipe 10 can be adjusted according to the weather temperature or indoor temperature. Because the rotating shaft 14 is connected to the outlet pipe 12 and the rotating plate 15 in the rotating shaft 14 and is also connected to the finger rod 16, the finger rod 16 is pushed to make the slider 17 at the bottom slide in the arc groove 18, and the tip of the front side of the finger rod 16 is adjusted. By aligning the angle of the finger rod 16 with the scale 19 of different flow rates, the flow rate of the airflow in the pipeline of the front cold and heat source pipe 10 can be accurately adjusted. Similarly, the heat source pipe of the rear cold and heat source pipe 10 can be adjusted by adjusting the finger rod 16 on the adjustment block 13 fixed to the outside of the air outlet pipe 12 at the top end of the heat source pipe of the rear cold and heat source pipe 10, pushing the finger rod 16 to drive the rotating plate 15 connected by the rotating shaft 14 to rotate synchronously with the finger rod 16, and aligning the sharp angle of the front side of the finger rod 16 with the scale 19 of different flow rates to achieve the adjustment of the airflow in the rear cold and heat source pipe 10.
