Frame type U-shaped double-fin tube heat radiator

Abstract

The invention provides a frame type U-shaped double-fin tube heat radiator, comprising a framework, a heat exchange pipe and fins, wherein a first stream inlet bag is fixedly connected with the left side of the framework; the first stream inlet bag is a trapezoidal box body and a sealed space formed between the bottom part of the first stream inlet bag and the framework is a second steam inlet bag; a stream pipe is arranged at the top of the first stream inlet bag; the heat exchange pipe passes through the framework and the bottom part of the first stream inlet bag and is fixedly connected with the framework and the first stream inlet bag; the fins are fixedly arranged on the heat exchange pipe; a steam outlet bag is fixedly connected with the left side of the framework; and the steam outlet bag is provided with a steam outlet pipe. According to the frame type U-shaped double-fin tube heat radiator, provided by the invention, the bottom surfaces of the U-shaped fins and the outer wall of the heat exchange pipe are in a surface contact, so that the combination is more compact, the heat transfer area is improved and the heat transfer is improved; and the single-chip heat exchange area of an old type heat exchanger is about 165 m<2> and the single chip heat exchange area of the heat radiator provided by the invention is about 220 m<2>. The frame type U-shaped double-fin tube heat radiator utilizes double layers of the steam bags so as to have a double-insurance function.

Description

technical field [0001] The invention relates to a finned tube radiator, in particular to a frame-type U-shaped double finned tube radiator. Background technique [0002] The finned radiator is a high-efficiency radiator in the shell-and-tube heat exchanger. The heat exchanger with this structure mainly uses the fins installed in series on the outer wall of the heat exchange tube to increase the heat exchange area, and obtain the heat exchange medium with turbulent flow. Form forced heat exchange, thus effectively improving heat exchange efficiency. This effective structure has been widely used, and such products have contributed to energy saving and emission reduction. The frame-type finned tube radiator is a new type of radiator enclosed by a frame with finned tubes. It has a compact structure and a beautiful appearance. At present, the drying system of most domestic salt-making enterprises uses frame-type finned tube radiators for heat exchange to dry the moisture in th...

AI Technical Summary

Problems solved by technology

After long-term production and operation, this kind of heat exchanger has exposed many shortcomings. Because the contact part between the fin and the heat exchange tube is in linear contact, the heat exchange effect is relatively low; in addition, the general frame finned tube radiator The end adopts a single-layer steam drum, once the steam leaks, the steam will directly enter the fluidized bed, resulting in a decrease in the drying efficiency of the fluidized bed and the discharge of wet salt
