Description
Technical field
The present invention relates to heat exchanger, especially a kind of efficient corrugated thin-wall condensing heat exchanger.
Background technology
At present, though condensing heat exchanger is of a great variety, form is different, determine the principal element of its heat exchange efficiency all to be: 1. big more by the ratio of the circulation volume of heat exchange journey and heat exchange area, its heat exchange efficiency is high more; 2. heat-transfer surface is thin more, and its heat exchange efficiency is high more.
Prevailing heat exchanger, it is made up of a cylindrical heat exchange core pipe inside by the heat exchange journey, one end of cylindrical heat exchange core pipe is entered the mouth by heat transferring medium, the other end of cylindrical heat exchange core pipe is exported by heat transferring medium, thick steel pipe of suit outside cylindrical heat exchange core pipe and form heat exchanger shell, the two ends of heat exchanger shell are recessed into and are connected with the two ends of cylindrical heat exchange core pipe, be communicated with the outlet of heat transferring medium inlet and heat transferring medium respectively at the two ends of heat exchanger shell, thus cylindrical heat exchange core pipe outside with the inner heat exchange journey that exports perforation with heat transferring medium inlet and heat transferring medium that forms of heat exchanger shell.
Circulated in by heat transferring medium by the heat exchange journey, heat transferring medium circulates in the heat exchange journey, between by heat transferring medium and heat transferring medium under the potential difference of the temperature difference, will be passed through heat-transfer surface that the tube wall by cylindrical heat exchange core pipe constitutes by the heat in the temperature difference between heat transferring medium and the heat transferring medium and thermaltransmission mode by the medium conduction transmits heat to the other side.
The heat exchange efficiency of conventional heat exchanger down is not only relevant, also relevant with the thickness of heat-transfer surface with the heat exchange area under the circulation volume, the heat exchanger under equal circulation volume, and heat exchange area is big more, the thickness of heat-transfer surface is thin more, and its heat exchange efficiency is high more.
Under the structure of above-mentioned heat exchanger, certainly lead to following drawback:
1. under the prerequisite of equal latus rectum, equal length, the heat exchange area minimum that constitutes by the tube wall of cylindrical heat exchange core pipe.
It is relatively poor that the tube wall of 2. cylindrical heat exchange core pipe bears the intensity of unidirectional external force, under the effect of unidirectional external force, make it that circle and depression take place to lose easily, must (for example be supported with thicker tube wall, if cylindrical heat exchange core pipe is that a circulation diameter is the steel pipe of 100mm, then pipe thickness is about 4.5mm), form thicker heat-transfer surface thus, and thicker heat-transfer surface must cause certain obstruction for the heat transmission by the medium conduction.
3. cylindrical heat exchange core pipe does not possess the function that absorbs thermal stress substantially.
For solving above-mentioned drawback, adopt the heat exchange core pipe of bellows structure more.But how to improve the heat exchange efficiency of corrugated tube heat exchanger, still do not have preferred plan at present.
Summary of the invention
The present invention is intended to solve the problem that the described heat exchanger of background technology exists, but and provides a kind of ultra-thin heat-transfer surface, super large heat exchange area efficient absorption thermal stress and inside to be provided with the efficient corrugated thin-wall condensing heat exchanger of obturator.
The present invention solves its technical problem and adopts following technical scheme:
A kind of efficient corrugated thin-wall condensing heat exchanger, comprise heat exchanger shell, place the heat exchange core pipe in the heat exchanger shell, it is characterized in that, described heat exchange core pipe is a thin-wall corrugated tube, the pipe thickness of described thin-wall corrugated tube is in 1.2% to 0.1% scope of internal diameter of tube body, the height of crest is in 8 to 20 times of scopes of pipe thickness, and bellows interior is provided with obturator.
Adopt the present invention of technique scheme, its outstanding effect is: by the heat-transfer surface of the super large heat exchange area that is made of the bellows tube wall, can significantly improve the heat exchange efficiency of heat exchanger, by the ultra-thin heat-transfer surface that constitutes by the bellows tube wall, not only has the ability that prevents to lose circle and depression under external force, also can significantly improve the heat exchange efficiency of heat exchanger, also possess and absorb thermal stress duty efficiently, be provided with obturator by bellows interior, can improve to greatest extent by the ratio of heat exchange journey circulation volume and heat exchange area, finally realize the purpose of high efficient heat exchanging.
The technical scheme that realizes the object of the invention also can have following preferred version:
Described thin-wall corrugated tube is by stainless acid resistant steel machine-shaping.
