Background technology
Traditional vacuum pipe solar water heater is a conventional vacuum tubular type solar water heater, shown in Fig. 1～2, one end of ordinary vacuum tube passes shell, heat-insulation layer and inner bag and inserts in the inner bag, seals between ordinary vacuum tube and the inner bag, and the other end of ordinary vacuum tube is bearing on the support.
Ordinary vacuum tube is made up of common outer tube, common inner tube and carriage, and the end face of an end of common outer tube and common inner tube is concordant and connect, the other end of common inner tube by bearing bracket on the inner surface of common outer tube.
Ordinary vacuum tube is subjected to solar light irradiation, absorb the heat energy of sunshine, water in the heating ordinary vacuum tube, convection current by water in ordinary vacuum tube and the inner bag, water in the heating inner bag, cold water flows into inner bag by water inlet pipe along the direction of arrow in the water inlet pipe, and hot water flows out inner bag by outlet pipe along the direction of arrow in the outlet pipe.
For between the hole that guarantees installation ordinary vacuum tube on the inner bag certain intensity and water-tight being arranged, traditional vacuum pipe solar water heater has 20～30 mm clearance between adjacent ordinary vacuum tube, this influences the thermal efficiency of conventional vacuum tubular type solar water heater, because the solar energy between the adjacent ordinary vacuum tube is not absorbed by ordinary vacuum tube.
One of method of the thermal efficiency of raising vacuum pipe solar water heater is the solid matter vacuum tube, by eliminating the gap between the adjacent vacuum tube, improves the quantity of vacuum tube, realizes improving the thermal efficiency of vacuum pipe solar water heater.
Direct solid matter ordinary vacuum tube is because direct solid matter ordinary vacuum tube is zero for the distance between the hole of inserting ordinary vacuum tube on shell, heat-insulation layer, the inner bag, can leak.
In Chinese patent ZL200420080484.7, tube connector inserts in the port of ordinary vacuum tube, realize the solid matter of ordinary vacuum tube, but the sealing device between the inwall of tube connector and tube connector and conventional vacuum pipe port reduces the water stream channel of the port of vacuum tube, influence the heat exchange of water in vacuum tube and the inner bag, simultaneously, each root tube connector all with the welding of the inner bag of water tank, the manufacturability of processing is relatively poor.
Summary of the invention
The purpose of this utility model is: provide a kind of interior pipe to prolong the solid matter vacuum pipe solar water heater, be used to improve the thermal efficiency of vacuum pipe solar water heater.
Technical solution of the present utility model: interior pipe prolongs the solid matter vacuum pipe solar water heater and comprises that interior pipe prolongs vacuum tube, tailstock, outlet pipe, water inlet pipe, overcoat, muff, interior bucket, one end of the interior pipe of length of interior pipe prolongation vacuum tube connects with interior bucket and seals, the end that interior pipe prolongs the short outer tube of vacuum tube connects with overcoat and muff, the other end of short outer tube is bearing on the tailstock, in pipe prolong do not stay the gap between the vacuum tube or only stay prevent in pipe prolong the gap that vacuum tube heat is splashed and risen and interfere mutually, outlet pipe and water inlet pipe pass overcoat, muff, interior barrel-shaped one-tenth connects and sealing.
Inner tube of the present utility model prolongs in the solid matter vacuum pipe solar water heater, inner tube prolongs vacuum tube and comprises long inner tube, short outer tube and carriage, one end of long inner tube with lack outer tube and connect and stretch out short outer tube, the other end of long inner tube by bearing bracket on the inner surface of short outer tube, long inner tube has certain distance between the outer tube and vacuumizes with lacking, the material of long inner tube and short outer tube is glass, and the outer surface of the long inner tube in short outer tube is coated with heat-absorbing material.
Inner tube of the present utility model prolongs in the solid matter vacuum pipe solar water heater, and the interior bucket of long inner tube insertion has under the condition of certain water stream channel at the port that guarantees long inner tube, can suitably reduce to insert the diameter of the interior barrel of long inner tube of locating, and short outer tube does not insert interior bucket.
Inner tube of the present utility model prolongs in the solid matter vacuum pipe solar water heater, and the inner tube that has the horizontal positioned inner tube to prolong vacuum tube prolongs the solid matter vacuum pipe solar water heater, and its inner tube prolongs the vacuum tube horizontal positioned; Also can there be the inner tube of bucket in the horizontal positioned to prolong the solid matter vacuum pipe solar water heater, bucket horizontal positioned in it.
The improvement principle that inner tube prolongs the solid matter vacuum pipe solar water heater is: by the solid matter of inner tube prolongation vacuum tube, improve the thermal efficiency of vacuum pipe solar water heater; End by long inner tube stretch out short outer tube and only long inner tube connects with interior bucket, inner tube is prolonged do not stay the gap between the vacuum tube or only stay to prevent that inner tube from prolonging the gap that vacuum tube heat is splashed and risen and mutually interfere, the solid matter of realization inner tube prolongation vacuum tube.
Inner tube of the present utility model prolongs the solid matter vacuum pipe solar water heater and compares with conventional vacuum tubular type solar water heater, because prolonging not stay the gap between the vacuum tube or only stay, inner tube prevents that inner tube from prolonging the gap that vacuum tube heat is splashed and risen and mutually interfere, the quantity of unit are vacuum tube is many, thermal efficiency height.
Inner tube of the present utility model prolongs the solid matter vacuum pipe solar water heater and compares with the tight-arranged solar vacuum-tube water heater of Chinese patent ZL200420080484.7, inner tube prolongs the solid matter vacuum pipe solar water heater does not need welding connecting tube, inner tube prolongs vacuum tube and compares with ordinary vacuum tube, inner tube prolongs the long inner tube of vacuum tube and stretches out short outer tube, the common inner tube of ordinary vacuum tube is not stretched out common outer tube, it is identical with other structure of ordinary vacuum tube that inner tube prolongs vacuum tube, when being processed to form inner tube prolongation vacuum tube, only need to stretch out in long inner tube the short outer tube of state lower link and long inner tube of short outer tube, the glass connecting process that connects in the end with common outer tube and the common inner tube of ordinary vacuum tube is close, makes inner tube prolong the good manufacturability of solid matter vacuum pipe solar water heater; In addition, current are unimpeded between long inner tube and the interior bucket, do not hinder, and the heat exchange of water is good.
