Abstract
The invention relates to an improved finned heat exchange pipe. The improved finned heat exchange pipe comprises a heat exchange pipe body (1) and fins (2), and is characterized in that a crossed inserting-in piece (3) is arranged in the heat exchange pipe body (1) and is spiral. The improved finned heat exchange pipe is used for an air bath type vaporizer device, and after low temperature media flow in from one end of the finned heat exchange pipe, the media move towards the outlet end in four ways; due to the arrangement of the inserting-in piece, the heat exchange area between the media in the heat exchange pipe body and the pipe wall is greatly improved; the crossed inserting-in piece is spiral, so that the media can have an obvious dispersion flowing effect; under the low Reynolds number condition, because of promotion of dispersion flowing, flowing of the media in the heat exchange pipe body is converted into turbulent flow; because the heat resistance of the heat exchange pipe body is minimum in the turbulent flow state, the heat exchange between the media and the heat exchange pipe body is further enhanced; and lowering of the heat transfer efficiency caused by dirt is reduced due to the spiral movement manner, and therefore the total heat transfer amount of an air bath type vaporizer is further improved.
Description
Technical field
The present invention relates to the parts in a kind of air-bathing gasifier device, specially a kind of fin heat exchange pipe of improvement.
Background technology
Fin heat exchange pipe in general air-bathing gasifier device, fin is set outside heat exchanger tube, cryogenic media in the fin heat exchange pipe with tube wall and tube wall outside fin in exchanged heat, total heat transfer coefficient is not high, once there is the formation of dirt in its pipe wall of heat exchange pipe simultaneously, can decline heat transfer efficiency, normally due to the presence of dirt can make operational efficiency decline 25% or so.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of fin heat exchange pipe of improvement, its heat exchange amount that can greatly improve cryogenic media and fin heat exchange pipe tube wall, so as to improve the overall heat transfer amount of air-bathing gasifier；Also can effectively suppress the formation of dirt simultaneously, it is ensured that the heat-transfer effect of air-bathing gasifier.
The object of the present invention is achieved like this：A kind of fin heat exchange pipe of improvement, is provided with " ten " font insert in the heat exchanger tube, " ten " the font insert is twist.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is used for air-bathing gasifier device, after cryogenic media is flowed into from one end of fin heat exchange pipe, divide 4 strands of media to outlet end motion, due to the setting of insert, medium is greatly improved with the heat exchange area of tube wall in heat exchanger tube, and " ten " the font insert is twist, medium is set to produce obvious disperse flowing effect, under the conditions of low reynolds number, due to the promotion of disperse flowing, the media flow in heat exchanger tube is set to be changed into turbulent flow, because its thermal resistance is minimum under turbulence state, further enhance the heat exchange of medium and heat exchanger tube, and the motion mode of spiral reduces the decline for causing heat transfer efficiency by dirt, so as to further improve the overall heat transfer amount of air-bathing gasifier.
