Abstract
The invention provides a pressure-bearing dual-cycle double-barrelled water tank liner, which is composed of an end cover, a liner pipe and an auxiliary electric heater. Two ends of multiple heat exchange tubes of a heat exchanger are communicated with two hollow spheres, and each hollow sphere is provided with an exhaust pipe and a circulating pipe which are communicated with the outside of the liner. In the invention, the heat exchanger is made from a high polymer material, and as the expansion and shrinkage coefficient of the high polymer material greatly differs from that of scale, scale is incapable of attaching on the heat exchange tubes and heat exchange spheres forever in a frequent cold heat exchange environment, thus higher heat transfer efficiency of the heat exchanger can be maintained. The multiple heat exchange tubes of the heat exchanger in the invention have big area surface, thus having small heat resistance, low heat exchange temperature, high heat transfer efficiency and small heat loss. In the invention, the liner is mainly made from the high polymer material and has the advantages of long service life, high reliability, simple production process, capability of realizing large-scale industrialized production and wide market prospect, a large quantity of metal raw materials can be saved, and the system production cost can be greatly reduced.
Description
Affiliated technical field
The present invention relates to a kind of condenser hot well liner, the two circulation bitubular inner water tanks of especially a kind of pressure-bearing.
Background technology
At present, solar water heater and electric heater mostly are stainless steel inner container with attemperater, or enamelling sheet steel inner bag, for realizing two circulatory functions, method commonly used is that spiral tube exchanger is installed in internal bladder cavity, because spiral tube exchanger has the big and high shortcoming of cost of circulation resistance, there is the people that above two kinds of inner bags are made big inner bag cover small inner container structure again, replace traditional spiral tube exchanger with the sandwich between two inner bags, solved the big difficult problem of circulation resistance though do like this, but cost height, the shortcoming of complex process is more outstanding, and this sandwich is compared with spiral tube exchanger, the external heat that has become the sandwich between two inner bags is heated in the inside of spiral tube exchanger, the heat loss of heat exchange circulation is increased; Also there is the people that inner bag is made big inner bag cover small inner container structure, sandwich inner storing water wherein, small inner container is made very little drum, heat transferring medium will be charged in the cask, use as heat exchanger, this way just it seems it is inner heat form, and circulation resistance is also little, but because cask is the metal material manufacturing, its coefficient of thermal expansion and contraction and incrustation scale are approaching, incrustation scale is easy to securely attached to top, and therefore, original surface area is very little cask just, after adhering to thick incrustation scale, its heat transfer property reduces greatly, and heat exchange efficiency also descends thereupon, and system's heat loss increases.
Summary of the invention
Big for the circulation resistance that solves stainless steel inner container, enamel inner container, cost is high, heat loss is big, the easy problem of fouling, the invention provides a kind of pressure-bearing pair circulation bitubular inner water tanks.
The technical solution adopted for the present invention to solve the technical problems is: inner water tank adopts macromolecular material, or modified polymer material, or strengthens macromolecular material, or the composite high-molecular material manufacturing; In the inner water tank wall enhancement layer is arranged; Many heat exchanger tube two ends of heat exchanger are connected with two hollow balls, have blast pipe and circulation pipe to be connected with the inner bag outside on the hollow ball.
End cap is hot melt grafting or hot melt butt joint with inner bag pipe mode of connection or glues together the compound connection that is connected or uses above technology.
Hollow ball, hollow hemisphere and tube interface thereof be with the integrated blow molding of blow molding technology, or adopt the injection mo(u)lding of injection molding process halfbody then again hot melt be one.
Heat exchanger tube adopts the extruding-out process manufacturing.Heat exchanger tube is pegged graft or the hot melt docking mode with hot melt, and the cavity by tube interface and hollow ball is interconnected.
The hollow hemisphere lower end is inserted pipe by hot melt inserting mode and heat exchanger and is connected and fixed.
The enhancement layer material of end cap, inner water tank is metal material or glass or carbon fibre or chemical fibre or steel fibre or ceramic fibre or natural fiber or string or fibrous composite; Inner bag is monotubular or the bitubular or many barrel structures.
Enhancement layer is tubulose or netted pipe or helix tube or fiber dispersion shape structure in end cap, the inner bag tube wall, the integrated extrusion molding of extruding-out process of enhancement layer in inner bag pipe, the inner bag tube wall, or adopt two or more macromolecular materials, macromolecule reinforcing material coextrusion mold, or use the injection molding process integrated injection molding; Enhancement layer injection molding process integrated injection molding in end cap, the end cap wall.
The invention has the beneficial effects as follows that heat exchanger is installed in the internal bladder cavity, is inner mode of heating, and higher heat exchange efficiency is arranged, and heat loss is little.
Heat exchanger of the present invention is the macromolecular material manufacturing, because the coefficient of thermal expansion and contraction of macromolecular material and incrustation scale differs greatly, in cold and hot frequent alternate environment, incrustation scale forever can't be attached on heat exchanger tube and the heat exchange ball, and this just makes heat exchanger keep higher heat transfer efficiency forever.
Many heat exchanger tubes of heat exchanger of the present invention have very big surface area, thereby thermal resistance is little and heat exchange temperature is low, the heat exchange efficiency height, and heat loss is little.
Many heat exchanger tubes of heat exchanger of the present invention are state in parallel and constitute circulation canal, and the total cross section of circulation canal is very big, and the flow resistance of circulatory mediator is very low, and this has just paved road for the natural circulation heating duty.
The present invention is the two periodic duty standards of pressure-bearing, and heat cycles liquid is antifreeze, can use at extremely frigid zones.
Of the present inventionly advance/water system is in the pressure-bearing duty, can save water level auto control system, and have simple to operate, the high advantage of spray pressure.
The present invention can save a large amount of raw material metals mainly by the macromolecular material manufacturing, significantly reduces the manufacturing cost of system, but and have the life-span long, reliability is high, the advantage of the simple large-scale industrial production of production technology, and vast market prospect is arranged.
