Abstract
The invention discloses an improved fin type heat exchange tube, which can improve heat exchange amount of a low-temperature medium and the side wall of the fin type heat exchange tube greatly, thereby improving the total heat transfer amount of an air-bath type carburetor, and simultaneously inhibiting the formation of dirt effectively to ensure heat transfer effect of the air-bath type carburetor. The improved fin type heat exchange tube comprises the heat exchange tube and fins, which is characterized in that the inside of the heat exchange tube is provided with a cross-shaped inserted piece.
Description
(1) technical field
The present invention relates to the parts in a kind of air-bathing gasifier device, be specially a kind of fin heat exchange pipe of improvement.
(2) background technology
Fin heat exchange pipe in the general air-bathing gasifier device, fin is set outside heat exchanger tube, cryogenic media in fin heat exchange pipe with tube wall and tube wall outside fin in carry out heat exchange, the overall heat transfer coefficient is not high, in a single day the formation of dirt is arranged in its heat exchanger tube tube wall simultaneously, heat transfer efficiency is descended, general because the existence of dirt can make operational efficiency descend about 25%.
(3) summary of the invention
At above-mentioned defective, the invention provides a kind of fin heat exchange pipe of improvement, it can improve the heat exchange amount of cryogenic media and fin heat exchange pipe tube wall greatly, thereby has improved the overall heat transfer amount of air-bathing gasifier; Also can suppress simultaneously the formation of dirt effectively, guarantee the heat-transfer effect of air-bathing gasifier.
Its technical scheme is as follows: it comprises heat exchanger tube and fin, it is characterized in that: be provided with " ten " font insert in the described heat exchanger tube.
It is further characterized in that: described " ten " font insert twist.
The present invention is used for the air-bathing gasifier device, cryogenic media is after an end of fin heat exchange pipe flows into, divide 4 strands of media to move to the port of export, because the setting of insert, the heat exchange area of medium and tube wall improves greatly in the heat exchanger tube, and described " ten " font insert twist, make medium produce tangible disperse flowing effect, under the low reynolds number condition, because the promotion that disperse is flowed, make the media flow in the heat exchanger tube change turbulent flow into, because its thermal resistance minimum under turbulence state, further strengthened the heat exchange of medium and heat exchanger tube, and the motion mode of spiral reduces the decline that is caused heat transfer efficiency by dirt, thereby further improved the overall heat transfer amount of air-bathing gasifier.
(4) description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is a left view of the present invention among Fig. 1.
(5) specific embodiment
See Fig. 1, Fig. 2 the present invention includes heat exchanger tube 1 and fin 2, is provided with " ten " font insert 3 in the heat exchanger tube 1, and " ten " font insert 3 twist.
Claims (2)
1, a kind of fin heat exchange pipe of improvement, it comprises heat exchanger tube and fin, it is characterized in that: be provided with " ten " font insert in the described heat exchanger tube.
2, according to the fin heat exchange pipe of the described a kind of improvement of claim 1, it is characterized in that: described " ten " font insert twist.
