Description
Technical field: the present invention relates to hot pipe type solar heat collector.
Background technology: at present, though the solar thermal collector brand is a lot, it substantially all is to utilize the vacuum glass tube heat collector accumulation of heat.Form by together inside and outside two glass tubes by being sleeved on for this vacuum heat collecting glass tube, and their upper end and lower end link to each other respectively, constitute the interlayer of sealing, vacuumize in it.Cold water directly enters in the glass tube, by heat transfer free convection, realizes the thermal power transfer of solar energy to water.Its weak point is: 1, in cloudy area, water temperature rises very slow;
2,, can cause glass tube to rise after the water in the vacuum glass tube heat collector freezes and split at cold district;
3, the incrustation scale of deposition easy-clear not in the glass tube with vacuum of long duration can cause water-heater efficiency to descend.
Summary of the invention: the heat transfer unit (HTU) that the object of the present invention is to provide a kind of heat conduction efficiency height and long-lived hot pipe type solar heat collector.The present invention mainly includes glass tube with vacuum, thermal conductance metal tab, heat pipe and interior pipe.Wherein, glass tube with vacuum is the jacket pipe that two glass bushing closed at both ends constitute vacuum.Establish in this glass tube with vacuum chuck and have coating for selective absorption.The heat pipe that is provided with the lower end closed upper end open in the above-mentioned glass tube with vacuum props up tube portion, is preferably between this heat pipe arm and the glass tube with vacuum and is provided with the thermal conductance metal tab, and it is good copper sheet of heat conductivility or aluminium flake.This thermal conductance metal tab is made up of contacted two the half-cylindrical thin-wall metal tubes that have an opening of flat face, its cross section becomes the X-shaped of symmetry, and the flat face of each half-cylindrical fin middle part is all established and recessedly in tube is semi-cylindrical cambered surface, the half-cylindrical cambered surface of these two fins surrounds one and is bordering on columniform space, its diameter is basic identical with the external diameter of the heat pipe arm that is positioned at it, make both keep tight contact, to reduce thermal resistance between the two.The upper end of above-mentioned heat pipe arm links to each other with through hole on the outer tube, and both axis normal can make heat-transfer working medium flow into easily in the heat pipe arm preferably not at grade like this.Be provided with two ends in the above-mentioned outer tube and all reach the outer interior pipe of outer tube, and the two ends of outer tube are fixing on inner pipe, outer tube and interior pipe chuck and heat pipe arm arm between the two constitutes a seal chamber, vacuumizes in it and the filling heat-transfer working medium.Above-mentioned glass tube with vacuum, thermal conductance metal tab, heat pipe and interior pipe constitute a heat transfer unit, and the pipe row that several above-mentioned heat transfer units constitute is the heat transfer unit (HTU) of heat pipe type solar heat collection device.The connected mode of above-mentioned heat transfer unit has multiple, it can be that the interior pipe at adjacent heat transfer unit two ends links to each other by welding or connector, it also can be to establish pipe in same in the outer tube of some heat transfer units, the outer tube that can also be some heat transfer units is connected as a single entity, and establishes pipe in same in it.
The course of work of the present invention is roughly as follows: the sun is passed to the heat pipe arm with heat energy by glass tube with vacuum and thermal conductance metal tab, make the liquid heat-transfer working medium vaporization in the heat pipe arm, rise in the chuck between outer tube and the interior pipe, by interior pipe the water in it is heated, meanwhile the steam state heat-transfer working medium is cooled into liquid state, under the gravity effect, enter again in the heat pipe arm, so circulation.
The present invention compared with prior art has following advantage: 1, novel structure, thermal resistance is little, heat exchange efficiency is high; 2, stable performance, durable in use.
