Abstract
The utility model discloses a corrugated pipe type heat exchanger with high efficiency, comprising a casing 1, heat exchange components 3, a heat source inlet 6, a heat source outlet 4, a heated body inlet 5 and a heated body outlet 2. The utility model is characterized in that the heat exchanger components adopt corrugated pipes with helical convexity and concavity. The utility model has the advantages of high heat exchange efficiency, less scaling, no thermal stress, small size, low cost, simple manufacture and stable and reliable quality.
Description
The utility model relates to a kind of novel heat exchange device-bellows-type heat exchanger.
Heat exchanger is a large amount of exchange heat equipment that use of industries such as heating power, chemical industry, oil, light industry, and it mainly is made up of heat exchange element in housing and the housing.
At present, the most frequently used heat exchanger still is a tubular heat exchanger, though advantage such as that it has is withstand voltage, high temperature resistant, reliable in structure, heat exchange efficiency is very low, has seriously caused the waste of the energy.The main cause that its heat exchange efficiency is low is because its adopts is that common steel pipe bundle is as heat exchange element.Because the inside and outside tube wall of its heat exchange element is a smooth surface, fluid is laminar condition in tube bank, and produces the boundary layer, promptly occurs thermograde from the tube hub to the tube wall.The appearance in boundary layer greatly reduces heat-transfer capability.In addition, the pipe fitting heat exchange area of this smooth surface is little, influences heat exchange efficiency again.
The utility model aims to provide a kind of novel heat exchange element, under the immovable situation of former tubular heat exchanger basic structure, realizes the raising of heat exchange efficiency and the improvement of other multinomial performance.
The purpose of this utility model is achieved in that on the basis of existing tubular heat exchanger structure, changes original level and smooth steel pipe into helical raised or helical form indent bellows, thereby has realized the very big improvement of heat exchanger performance.
Major advantage of the present utility model is:
1, heat exchange efficiency height;
After the heat exchange element surface increases helical raised or indent, changed the laminar condition of medium in the pipe, the media flow state becomes turbulent flow and eddy flow state, and this state has been broken the boundary layer effectively, increase the interior flow process of pipe of medium simultaneously, also increased the surface area of heat exchange element.In addition, after tube wall processed the ripple that has helical raised or indent, its voltage endurance capability improved greatly, and like this, the tube wall of heat exchange element can attenuate, and the heat exchange element capacity of heat transmission behind the attenuate improves many.Because above all multifactor effects, the bellows-type heat exchanger improves heat exchange efficiency 3-5 doubly than common tubular heat exchanger.
2, less scaling;
After heat exchange element changes the bellows with helical raised or indent into, produced certain elasticity, this elasticity has vibration by a small margin when making element work, and this motion can make more crisp dirty sheet come off, and therefore has self-cleaning ability.Also help to prevent the formation of dirty body when the flow regime of medium is turbulent flow in addition.
3, eliminated thermal stress;
Because bellows is flexible, can stretch, therefore solved the problem of the thermal stress that heat exchange element and shell body produce because of thermal deformation is inconsistent.
4, volume is little, cost is low;
After exchanger heat efficient improved, smaller volume can be reduced investment outlay.
5, manufacturing is easy, and steady quality is reliable.
Describe its technical solution in detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the structural representation of bellows-type heat exchanger.
Referring to Fig. 1, mainly include housing 1, heat exchange element 3, thermal source import 6, thermal source outlet 4, heated object import 5, heated object outlet 2, be characterized in that heat exchange element has adopted the bellows that has helical raised or indent, this bellows is to utilize thin-wall stainless steel (for example adopting the stainless steel tube of 0.6m) to produce by plastic deformation method.
