Abstract
The invention provides a pressure-bearing double-cycle all-plastic water tank liner, which is composed of an end cover, a liner pipe and an auxiliary electric heater. An annular groove on the end cover is connected with the water tank to form an annular hole, and the annular hole is communicated with the holes in the liner pipe wall and is communicated with the outside via a pipe of the annular groove. Multiple holes in the liner pipe wall are connected in parallel to form a circular channel, the circular channel has a large total cross section, and the circular medium has very low flow resistance, thus laying a foundation for realizing the working state of heating by natural circulation. In the invention, the heat exchange surface is big enough, thus the heat resistance is small, the heat exchange temperature is low, the heat exchange surface is prevented from scaling, and higher heat transfer efficiency can be maintained forever. The liner in the invention is mainly made from a polymer material and has the advantages of long service life, high reliability, simple production process, capability of large-scale industrialized production and wide market prospect, a great quantity of metal raw materials are saved, and the system manufacturing cost is greatly lowered.
Description
Affiliated technical field
The present invention relates to a kind of condenser hot well liner, the overall plastic 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, because there is the intercrystalline corrosion problem in the stainless steel inner container weld seam, service life, weak point was a still unsolved world-famous puzzle, though the trend of using the enamelling sheet steel inner water tank is arranged both at home and abroad in recent years, but steel and enamel material coefficient of thermal expansion and contraction must be highly consistent harsh requirement, make the quality of this inner bag be difficult to guarantee.Moreover, more than two kinds of inner bags must after adding heat exchanger, could realize pair circulatory functions.In a word, the inner bag of two kinds of structures all has life-span weak point, complex process, shortcoming that price is high more than.
Summary of the invention
For the solution stainless steel inner container, enamel inner container is of poor quality, the life-span is short, problem of ultra-high price, the invention provides the overall plastic inner water tanks of the two circulations of a kind of pressure-bearing.
The technical solution adopted for the present invention to solve the technical problems is: in the end cap wall, in the inner bag tube wall enhancement layer is arranged; Water inlet pipe and water outlet pipe and cannelure are arranged on the end cap, pipe is arranged on the cannelure; A plurality of holes are arranged in the inner bag tube wall, and cannelure on the end cap and the pipe back that combines forms looping pit, and the interior hole of looping pit and tube wall is connected, and looping pit communicates with the external world by the pipe on the cannelure.
Inner bag adopts the macromolecular material manufacturing, or is modified polymer material, or is the enhancing macromolecular material, or is the composite high-molecular material manufacturing.
Enhancement layer, the water inlet pipe and water outlet pipe on the end cap and cannelure in end cap, the end cap wall, the pipe on the cannelure adopt the injection molding process integrated injection molding; Electric heater is installed on the end cap.
The injection molding process integrated injection molding is adopted in enhancement layer, the hole in the inner bag tube wall in inner bag pipe, the inner bag tube wall, or adopts the integrated extrusion molding of extruding-out process, or adopts more than one macromolecular material co-extrusion modling.
The cross sectional shape of inner bag tube wall endoporus is circle or oval or triangle or polygon or irregular shape.
Enhancement layer in the end cap wall, in the inner bag tube wall is that metal material or glass or carbon fibre or chemical fibre or steel fibre or ceramic fibre material are manufactured; Enhancement layer in the end cap wall, in the inner bag tube wall is helix tube, tubulose or netted or fiber dispersion shape structure.
Cannelure on the end cap is that hot melt is pegged graft or hot melt docks or spiral is connected or glues together connection with inner bag pipe mode of connection, or the compound connection of above mode of connection.
The invention has the beneficial effects as follows that a plurality of holes in the inner bag tube wall provide circulation canal for heat cycles, wall of inner container itself is exactly a heat exchanger, has so both saved raw material, has improved heat transfer efficiency again.
A plurality of holes in the wall of inner container of the present invention are state in parallel and constitute circulation canal, and the total cross section value 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 heat exchange area, thereby thermal resistance is little and heat exchange temperature is low, and never fouling on the heat-exchange surface can keep higher heat exchanger effectiveness forever.
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 simple large-scale industrial production of production technology, and vast market prospect is arranged.
