Description
Technical field
The present invention relates to the heat exchanger that a kind of inside and outside fin plate type heat exchanger tube is formed, it mainly is made up of a kind of novel heat-exchange tube, can be applied in the fluid heat transfer process of industries such as chemical industry, petrochemical industry such as gas-liquid exchange, the exchange of liquid liquid, the exchange of gas gas.
Background technology
The heat exchanger of present domestic use mostly is tubular heat exchanger and spiral-plate heat exchanger.Their main feature is that the inside and outside heat exchange area of pipe equates.When the exchange media that differs bigger when exchange coefficient carried out exchange heat inside and outside pipe like this, owing to its disequilibrium does not reach desirable switching purpose, heat exchange efficiency was relatively low.Though the chip heat-exchange tube of spreading the wings in a kind of is arranged now, it is to adopt the heat exchange area that strengthens the low side of thermal conductivity factor, and the same with the heating principle of radiator, inside is water, external heat be air because the air thermal conductivity factor is low so strengthen its heat exchange area.Because it has just strengthened the heat exchange area of inside tube, when the outside also was the low medium of thermal conductivity factor, heat-transfer effect was just not too obvious, so its scope of application is narrower.
Summary of the invention
In order to overcome the existing above-mentioned deficiency of chip heat-exchange tube of spreading the wings in existing, the present invention has announced the heat exchanger that a kind of inside and outside fin plate type heat exchanger tube is formed, it mainly is made up of a kind of novel heat-exchange tube, and tube fluid and extratubal fluid carry out the heat transmission by heat exchanger tube.Inside and outside fin plate type heat exchanger tube is a kind of new and effective heat exchanger tube of forcing to improve pipe surfaces externally and internally heat transfer performance that has.
The technical solution adopted for the present invention to solve the technical problems is: the inside and outside both sides at heat exchanger tube increase the wing plate simultaneously, thereby make the medium that outside thermal conductivity factor is low in the heat-exchange tube manage inside and outside flow velocity, improve the purpose that its heat exchange area reaches the inside and outside heat-transfer effect of raising pipe by accelerating it by inside and outside wing plate.Concerning spiral wing plate, mainly be the flow velocity of accelerating lateral media in the spiral wing plate, concerning straight wing or its distortion, mainly be the heat exchange area of lateral media in improving, improve the inside and outside heat-transfer effect of pipe and the perfect condition of heat balance thereby reach.Owing to improved heat exchanger effectiveness, thereby made cooling water temperature improve, reduced the consumption of cooling medium, thereby reached the purpose that reduces running cost.
The major technique content of the heat exchanger that the inside and outside fin plate type heat exchanger tube that the present invention announced is formed is: the side surface area that the medium heat conduction coefficient is high is little, and flow velocity is slow, and the side surface area that the medium heat conduction coefficient is low is bigger, and flow velocity is very fast.For spiral wing plate medium in certain length because helical form is advanced and has been improved its movement velocity, strengthened the heat transfer efficiency of the low side of medium heat conduction coefficient, and then reached the in a basic balance of heat exchange.Be the turbulence state for main still the increasing of considering of straight wing plate or its distortion when its heat exchange area and fluid flow, strengthened heat transfer equally, reach the in a basic balance of heat exchange.The heat exchanger that the inside and outside fin plate type heat exchanger tube that the present invention announced is formed, owing to adopt the straight wing of ripple or the straight wing of broken line of screw type, straight wing and distortion thereof in the interior outside of heat exchanger tube, effectively raise the inside and outside heat exchange effect of pipe, the heat exchanger that therefore inside and outside fin plate type heat exchanger tube is formed has the scope of application widely.
Generally speaking, the main feature of the heat exchanger of the inside and outside fin plate type heat exchanger tube composition of the present invention's announcement is:
1, heat exchange efficiency height is compared 3～8 times of raisings with traditional heat exchanger.
2, the resistance that flows of fluid is little, and promptly pressure falls little.
3, compact conformation, low cost of manufacture.
4, be convenient to install, overhaul easily.
5, operating flexibility is big, operability good.
6, should not stop up, be convenient to scale removal.
The invention will be further described below in conjunction with drawings and Examples.
