Abstract
The invention provides a pressure-bearing dual-cycle all-plastic water tank liner of a heat exchanger, which is composed of an end cover, a liner pipe and the heat exchanger. Two ends of multiple heat exchange tubes of the 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 cold heat frequent alternation 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 exchange 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 inner water tank, the overall plastic heat exchanger inner water tank of the two circulations 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 inside heating has been become external heat, the heat loss of heat exchange circulation is increased.
Summary of the invention
For solving the problem that circulation resistance is big, cost is high, heat loss is big of stainless steel inner container, enamel inner container, the invention provides the overall plastic heat exchanger inner water tank of the two circulations of a kind of pressure-bearing.
The technical solution adopted for the present invention to solve the technical problems is: 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.
Tube interface on hollow ball, the hollow ball is 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 hollow ball and heat exchanger tube be macromolecular material with material, or modified polymer material, or strengthen macromolecule, or composite high-molecular material.
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.
Screw 6 is arranged on the seal cover 26; Have cannelure 5 on the nut 7, have cannelure 3 on the seal cover 26, be placed with waterproof apron 4 between cannelure 3, the cannelure 5.
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.
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 has enough big Re Jiao Change area, thereby thermal resistance is little and Re Jiao Change temperature is low, and is less scaling on the Re Jiao Change face, can keep higher Re Jiao Change efficient forever.
Of the present invention mainly by the macromolecular material manufacturing, can save a large amount of raw material metals, significantly reduce the manufacturing cost of system, but and have the life-span long, reliability is high, the simple large-scale industrial production of production technology, and vast market prospect is arranged.
