Abstract
The utility model relates to a ring-segment corrugated metal pipe for a heat exchanger, which is made of metal material forming a hollow pipe shape. The hollow pipe forms a ring-segment shape continuously composed of a plurality of convex rings and concave rings with gaps; each convex ring forms a cylindrical / arc shape; each concave ring forms an inwards concave arc shape. The width of the convex ring is greater than the width of the concave ring; the ratio of the width of each convex ring and the width of each concave ring is between 3 and 5. Adjacent inner and outer arcs are transited by curves, and therefore, a longitudinal side in a longitudinal cross section forms a corrugated smooth fluctuation. The heat exchanging element made by the utility model has the advantages of obviously raising the heat exchanging efficiency of heat exchanger, saving the energy, better solving the scaling problem, prolonging the service life of the equipment and saving the equipment investment.
Description
The utility model relates to the tubing that the heat exchanger heat exchange element uses, a kind of specifically heat exchanger corrugated metal pipe material of link.
Heat exchanger is an exchange heat equipment, is widely used in heating power, chemical industry, pharmacy, oil, light industry, smelting industry.At present, the most frequently used heat exchange element of heat exchanger is a straight tube, and some straight tubes rearrange heat-exchanging tube bundle, though it has withstand voltage, high temperature resistant and advantage of simple structure, but because of tube wall inside and outside it is a smooth surface, fluid is laminar condition in tube bank, and produces the boundary layer, occurs thermograde from the tube hub to the tube wall, reduce heat-transfer capability, the heat exchange area of adding its even surface is little, thereby heat exchange efficiency is low, and incrustation is serious.
For this reason, the producer that also has has adopted spiral type corrugated metal tube to make heat exchange element, and this heat exchange element has changed the laminar condition of media flow in the pipe, has increased the surface area of heat exchange element, improved transport heat efficient, but scale problems does not solve fully yet.
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of heat exchanger with the corrugated metal pipe material of link, can further improve heat exchange efficiency with the heat exchange element of its making, energy-conservation, and solve the incrustation problem preferably, and prolong service life of equipment, save equipment investment.
The purpose of this utility model is achieved in that
A kind of heat exchanger corrugated metal pipe material of link, be hollow tubular, make with metal material, it is characterized in that: this hollow pipe constitutes the link shape continuously by some bulge loops, scrobicular ring are alternate, each bulge loop is outer convex cylindrical/circular shape, and each scrobicular ring is the indent circular shape, and the width of each bulge loop is greater than the width of scrobicular ring, and the ratio of each bulge loop width and scrobicular ring width is between 3-5, and each adjacent inside and outside circular arc makes the longitudinal edge in its longitudinal cross-section be wavy smooth fluctuating with curve transition.
During enforcement, the bulge loop diameter of described link bellows is between 10-50mm, and pipe thickness is between 0.5-2.5mm.
Described tubing uses stainless steel, copper material to make.
The utility model has following actively useful effect:
1. the inside and outside wall of the heat exchange element made from this metal tubing is made of continuous arcuation projection and arcuation groove, its longitudinal section is wave and plays, lies prostrate shape, making the interior media flow of pipe become laminar flow is turbulent flow, eliminated the trapezoidal profile of temperature, it is consistent with tube wall temperature to reach the interior center of pipe, improves heat exchange efficiency.
2. media flow rises, lies prostrate and advance along the arcuation projection and the arcuation groove bend of each link, and flowing time is long, and area of dissipation is big, thereby has improved heat exchange efficiency significantly.
3. medium flows along link shape projection and groove, be subjected to flow passage resistance force of waterproof to form turbulent flow and turbulent flow, when the convex arc inwall flows to the concave arc inwall, impurity wave in the medium is evoked, and impurity is with the outflow of advancing of liquid stream, thereby less scaling, the more spiral type corrugated pipe of its wave activity is more fierce, (resistance when flowing because of the spiral cell wall along spiral type corrugated pipe is little than link formula bellows), thereby it is more thorough, less scaling, stifled to solve the also more spiral type corrugated pipe of scale problems.
4. heat exchange efficiency height, thereby energy savings.
5. the structure of link shape has increased intensity, the rigidity of heat exchange element, thereby tube wall can be thinner, reduces manufacturing cost.
6. incrustation is few, thereby long service life, and equipment investment is few.
7. the corrugated metal pipe material of this link can be used for manufacturing, transformation and the boiler improvement of condenser, oil cooler, air preheater, radiator and various heat exchangers.
Now in conjunction with the accompanying drawings with preferred embodiment:
Fig. 1 is a structural representation of the present utility model, is the cylindrical embodiment of bulge loop;
Fig. 2 is the side view of Fig. 1;
The same Fig. 1 of Fig. 3 is the embodiment of circular arc for bulge loop.
The heat exchanger of the present utility model corrugated metal pipe material of link, be hollow tubular, make with metal material, its structure please refer to Fig. 1 Fig. 2, this hollow pipe is by some bulge loops 1, scrobicular ring 2 alternate continuous formation link shapes, each bulge loop can be the evagination cylindrical shape and see Fig. 3, also can be the evagination circular shape and see Fig. 1, each scrobicular ring is the indent circular shape, the width a of each bulge loop is greater than the width b of scrobicular ring, and the ratio of each bulge loop width a and scrobicular ring width b is between 3-5, and each adjacent inside and outside circular arc makes the longitudinal edge in its longitudinal cross-section be wavy smooth fluctuating and is beneficial to flowing of medium with curve transition.
During enforcement, the bulge loop diameter of described link bellows is between 10-50mm, and pipe thickness is between 0.5-2.5mm.
In preferred embodiment, described tubing uses stainless steel, copper material to make.
