Heat exchanger with corrugated pipe coil structure provided with internal duct and external duct

Abstract

The invention discloses a heat exchanger with a corrugated pipe coil structure provided with an internal duct and an external duct, which comprises an inlet, an outlet, a corrugated pipe, a dome, an internal ring bushing, an external ring bushing, a fan and a bracket. When fluid media to be in heat exchange flow in the corrugated pipe in the heat exchanger from the inlet, form a turbulent flow in a pipe wall with a corrugated structure and carry out heat exchange with air in the internal duct and the external duct outside the corrugated pipe via the wall of the corrugated pipe, the fan discharges air in the internal duct and the external duct, and the fluid media are discharged from the outlet after the heat exchange performed in the corrugated pipe in a spiral way. The heat exchanger has the advantages of high heat exchanger effectiveness, simple structural technology, light weight, integration, and the like, and the fluid media in the pipe coil after the heat exchange have even temperature, thereby the heat exchanger can be used for heat exchange of air, liquid and air-liquid mixing substances. When the corrugated pipe adopts resistant materials, the heat exchanger can be used for heat exchange for corrosive liquid media.

Description

technical field [0001] The invention relates to a heat exchanger, which is especially suitable for heat dissipation or refrigeration of liquid, gas, and gas-liquid mixture, and can be used in chemical industry, construction and other fields. Background technique [0002] At present, most heat exchangers use finned heat sinks, and the arrangement of finned heat sinks is mostly parallel. Slow, the pipeline is long, the bending radius is small, the fluid resistance is large, easy to leak, the manufacturing process is complicated, and the manufacturing cost is higher, such as disclosed heat exchangers such as CN2463756Y. CN2752664Y discloses a radiator with a metal coil structure with internal and external threads. The coil structure is "mouth" or "L". Stainless steel pipes / threaded pipes are assembled with heat dissipation fins, but whether it is a coil structure heat exchanger or a traditional heat exchanger with finned radiators, when used in some closed equipment or places,...

AI Technical Summary

Problems solved by technology

[0002] At present, most heat exchangers use finned heat sinks, and the arrangement of finned heat sinks is mostly parallel. Slow, long pipeline, small bending radius, large fluid resistance, easy to leak, complicated manufacturing process, high manufacturing cost, such as disclosed heat exchangers such as CN2463756Y

CN2752664Y discloses a radiator with a metal coil structure with internal and external threads. The coil structure is "mouth" or "L". Stainless steel pipes / threaded pipes are assembled with heat dissipation fins, but whether it is a coil structure heat exchanger or a traditional heat exchanger with finned radiators, when used in some closed equipment or places, where There is no active air velocity in the space (such as the chassis, etc.), the heat exchange efficiency is low, and if there are temperature-sensitive components in the space (such as the chassis), it is easy to cause failure

[0003] In addition, the above-mentioned structure is usually not corrosion-resistant. In order to prevent corrosion, the above-mentioned types of heat exchangers are mostly assembled with stainless steel pipes with cooling fins, or with anti-corrosion inner tubes, which affects the heat dissipation efficiency and requires die-casting technology. , high manufacturing cost
