Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to a hot air internal circulation type fin heat exchanger. Background Art

[0002] Fin heat exchanger is a heat exchange device that enhances the heat transfer process by adding fins to the base tube. It allows the heat of the hot fluid to be transferred to the cold fluid. The hot air internal circulation fin heat exchanger is a high-efficiency heat exchange device that transfers heat through the internal fin tubes. These fins increase the heat dissipation area, thereby improving the heat transfer efficiency. The hot medium flows through the internal pipes, while the air flows between the fins, and the heat exchange between the two is carried out through the tube wall and the fins.

[0003] In the actual operation process of the existing hot air internal circulation fin heat exchanger, there is no effective mechanism to clean and maintain the fins. As a key part of the heat exchanger, the fins are prone to accumulate dust and other impurities on their surface. Over time, these accumulated dust will form an insulating layer, which hinders the effective transfer of heat, thereby reducing the efficiency of the heat exchanger. In addition, the existing hot air internal circulation fin heat exchanger is not designed to achieve sufficient circulation of heat flow. The circulation of heat flow is crucial to improving heat exchange efficiency because it ensures that heat is evenly distributed between the fins, thereby maximizing the effect of heat exchange. If the heat flow cannot circulate effectively, heat will accumulate in some areas, while insufficient heat may occur in other areas. This not only reduces the overall heat exchange efficiency, but may also cause local overheating or uneven cooling, affecting the stable operation of the system.

[0004] Therefore, in order to solve the above problems, the present application provides a hot air internal circulation fin heat exchanger.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
