Abstract
The utility model discloses a copper corrugated tube heating exchanger, which comprises a bottle body, a heating exchange tube nest and carbon steel tube sheet. The utility model is characterized in that the copper corrugated heating exchanging tube nest inserting in the volume bottle body is positioned on the bottle body, the tube ports of multi copper corrugated tubes insert into the multi through holes on the carbon steel tube plate correspondingly and are connected tightly in the expansion under force, the carbon steel tube sheet is formed to be a copper corrugated tube heating exchanger through the connection of the flange and bottle body sealed bolts. The utility model has the advantages of simple structure, strong resistance to the corrosion, high heating induction coefficient, sanitation and environment protection, long service life, low operation and service cost and strong practicality and applicability and produces the good social and economical effectiveness after put into production.
Description
Technical field
The utility model relates to technical field of heat exchangers, relates to a kind of corrugated tube heat exchanger specifically.
Background technology
As everyone knows, heat exchanger is widely used in HVAC as heat-exchange apparatus, chemical industry, fields such as petrochemical industry, heat exchanger generally comprises three kinds of citation forms: storage type is arranged, Instant heating type and semi instant heating heat exchanger, and various forms of heat exchanger kinds are a lot, common have plate type heat exchanger and a pipe heat exchanger, pipe heat exchanger divides straight tube and bellows structure again, though the heat exchanger of various versions all has application, but corrugated tube heat exchanger then is the most frequently used a kind of form, especially in requiring the high domestic water heat exchanger of cleannes, because the specific (special) requirements of environmental protection, general special material and the structure of adopting manufactures the enhanced heat exchange device, wherein the corrugated stainless steel tubing heat exchanger applications is very general, the characteristics that energy-efficient consumption reduction and antiscaling, descaling are arranged, but also exist acid, alkali, the shortcoming that the corrosion resistance of salt is relatively poor and heat transfer coefficient is on the low side, how according to these characteristics of corrugated tube heat exchanger, solving the problem that the corrugated tube heat exchanger corrosion resistance is relatively poor and heat transfer coefficient is on the low side, is to need the task of finishing in the art.
Summary of the invention
Order of the present utility model provide a kind of simple in structure, corrosion resistance is strong, heat transfer coefficient is high, environment-protecting clean, is applicable to the corrugated tube heat exchanger of domestic water field heat exchange.
In order to achieve the above object, the utility model adopts following structural principle, concrete structure is: a kind of corrugated tube heat exchanger, comprise tank body, heat-exchanging tube bundle, carbon steel tube plate, be characterized in: the copper corrugated pipe heat-exchanging tube bundle that inserts in the volume tank body is set on the tank body, carry out the intensity swelling behind the corresponding a plurality of through holes that insert on the carbon steel tube plate of the mouth of pipe of many copper corrugated pipes and be connected, carbon steel tube plate is connected with the pot body closing end bolt by flange.
Above-mentioned described copper corrugated pipe is by tangent continuously inside and outside shape of big or small circular arc such as undulatory structure.
Structural principle of the present utility model is such: copper is a kind of comparatively valuable non-ferrous metal, stable performance, the heat transfer coefficient height, good corrosion resistance, to most acid, alkali, salt all has stronger resistance to corrosion, these special physicochemical properties that utilize copper material are through the joint that expands, flat mouthful, welding, painted, flaw detection, operations such as pressure test, the moulding bellows, correspondingly with a plurality of through holes on the carbon steel tube plate again carry out the intensity swelling and be connected, form heat exchanger, copper corrugated pipe then is a kind of by tangent continuously inside and outside shape of big or small circular arc such as undulatory efficient thermoexcell, difference in height between its crest and the trough makes fluid produce strong disturbance through being subjected to tubular influence behind the pipe, thereby be issued to turbulence state at low flow velocity, improved heat transfer coefficient greatly, the profile of bellows has determined its many special performances simultaneously, form under the tubing linear expansion coefficient different as undulatory profile and to separate with dirt, the profile of ripple has formed many little expansion joints, offset stress, make that heat exchanger tube can the big pressure reduction of the anti-big temperature difference, low flow velocity is issued to turbulent flow, pressure drop reduces makes that also the energy consumption of fluid conveying machine reduces in the technological process, and copper is lighter than stainless steel proportion, but be used for the equipment weight reduction, save the each side expense, effectively raised the performance of equipment simultaneously in the field of its adaptation.
Through hole carries out the structure that the intensity swelling is connected on above-mentioned copper corrugated pipe heat-exchanging tube bundle and the carbon steel tube plate owing to having adopted, make that the utility model is simple in structure, corrosion resistance is strong, heat transfer coefficient is high, environment-protecting clean, adaptability be strong, strengthened the service life of heat exchange equipment greatly, use cost and maintenance cost have been reduced, the domestic water heat exchange field that is particularly useful for the high environmentally-friendly sanitary of requirement cleanliness factor, have stronger practicality, put into production and can create good social benefit and economic benefit.
