Description
Technical field
The present invention relates to the low solar energy heat collector of putting short tube imbibition core of heat collecting element glass heat pipe.
Background technology
The solar water appliance of heat-pipe vacuum heat collecting pipe manufacturing has anhydrous Energy Efficiency Ratio height in the pipe, meet safe drinking water standard, single tube damages advantage such as in the same old way work.Therefore.Anhydrous solar vacuum hot water device might capture the increasing market share in the pipe.
Existing a kind of workload fills all-glass heat pipe vacuum collector tube solar water heater seldom, and the heat pipe inwall adopts light-pipe structure, heat-pipe vacuum heat collecting pipe about 45 degree that tilt to install.Under non-heat exchange state, can observe the heat pipe bottom has liquid refrigerant to gather.
To its carry out with pipe in the all-glass vacuum thermal-collecting tube solar water heater check experiment of water, find that the slow earlier back of intensification situation of heat pipe solar energy water heater is fast.Judgement is that the heat pipe start-up course is long, the startup stage of heat pipe, the heat collector tube product can not full power operation thereby heat up slow, operation of heat collector tube device full power thereby quick heating after heat pipe starts.
The heat pipe of investigating all-glass heat pipe vacuum collector tube starts: because the working medium that is collected in the heat pipe bottom makes these liquid refrigerants can not participate in the two phase flow heat transfer circulation rapidly usually because its temperature of minute surface shading that is formed by getter rises slowly.Simultaneously, though because the temperature at inner other positions, heat pipe hot junction is high is in dry state and can not contributes to thermal-arrest in a very long time.Rely on the glass heat pipe tube wall heat transfer near the bottom to make liquid refrigerant vaporization and circulation participate in two phase flow heat transfer gradually later on, heat pipe is finished start-up course and is entered normal operating conditions.Problem is in the winter time, and the start-up course of heat pipe may continue more than two hours, and this makes that the performance of some glass heat pipe thermal-collecting tube can not be obviously good than the all-glass vacuum thermal-collecting tube of managing interior water, and the advantage of heat pipe fails to give full play to.
Glass surface is not suitable for processing stria to form bigger capillary lift.
Employing arranges to have enough large-area core net at the glass heat pipe inner surface, though can utilize capillarity to solve the long problem of heat pipe start-up course, but can make the bigger increase of cost, more seriously also can fill more, the too high increase greatly that has a big risk that causes the bombing accident of vapour pressure when making empty solarization of working medium because of inside.When 0.2% when for example working medium filling weight/heat pipe plot ratio is from 2 milliliters/1000 milliliters are brought up to 5 milliliters/1000 milliliters 0.5%, the highest saturated vapor pressure increases to about 10 atmospheric pressure of 180 ℃ from about 3.7 atmospheric pressure of 140 ℃, but inside heat pipe internal pressure when 140 ℃ of about 3.7 atmospheric high-vapor-pressures continue to be warming up to 180 ℃ only has about 4 atmospheric pressure.Because the glass voltage endurance capability is limited,, the least possiblely when heat pipe work again hold back liquid refrigerant with minimizing working medium filling weight so the liquid refrigerant position height in the time of should managing to raise heat pipe and start is accelerated to start.
Chinese invention patent 200410012193.9 Explosion-proof all-glass solar energy vacuum collecting tubes have disclosed a kind of Explosion-proof all-glass solar energy vacuum collecting tube, and the liquid refrigerant filling weight is 0.1～0.5%V in its heat pipe, and wherein V is the volume in the heat pipe.All be converted into vapour phase when making it reach a certain critical-temperature, when temperature continued to raise, pressure raise according to the rule of vapour phase, thereby had significantly reduced the operating pressure in the heat pipe under the condition of high temperature ...Simultaneously, in heat pipe, set up sorbing material, to guarantee that heat pipe quick starts once more.But this patent of invention comprises that in heat pipe sorbing material sticking working medium that heat pipe evaporator section middle part is provided with adds quick heating pipe and starts this mode and still can bring when increasing working medium filling weight and empty the solarization internal pressure or start still slower problem.Suppose: set originally and be limited to 4 atmospheric pressure on 4.4 millimeters of inner glass tube internal diameters, 58 millimeters of cover glass tube external diameters, long 2 meters the internal pressure of all-glass vacuum heat collector tube pipe, emptyly shine 230 ℃ of maximum temperatures, water is made working medium, calculating can get about 3 liters of inner glass tube volume.The saturated vapor pressure table of looking into water vapour is as can be known: whole working medium filling weight of working medium vaporization just in the time of 135 ℃, its saturated vapor pressure is 3.2 atmospheric pressure and when shining 230 ℃ of temperature in high-altitude, internal pressure reaches 4 atmospheric pressure and promptly equals the inner glass tube internal pressure limit.And the quality volumetric ratio of steam is 1.7 milliliters/liter can check in 135 ℃ the time.The working medium filling weight of this thermal-collecting tube is 1.7 milliliters/liter=5.1 milliliters of 3 liters of *.(5.1 milliliters of working medium are on the low side for existing thermal-collecting tube, can occur drying up in the bottom, hot junction, but this problem do not done expansion here).At this moment, quick heating pipe starts and imbibition material is set in the middle part of inside heat pipe in order to add.Suppose that the imbibition material that is increased carries sticking 1.5 milliliters of working medium have altogether been arranged when the heat pipe operate as normal, and therefore aggravate inside heat pipe hot junction dry-out, dry hot junction does not participate in heat exchange has a greatly reduced quality the efficient of thermal-collecting tube.For fear of the heat-collecting capacity loss that brings because of the hot junction is dry.Must increase the working medium filling weight remedies heat pipe when work and is put forward that part of working medium that sticking has by imbibition material.Suppose that the working medium filling weight that increases also is 1.5 milliliters, the quality volumetric ratio of the steam when then working medium is just all vaporized from 1.7 milliliters/go up and rise to 2.2 milliliters/liter, the critical-temperature of the highest saturated vapor pressure correspondence at this moment rises to 145 ℃ from 135 ℃; Correspondingly, when shining 230 ℃ of temperature in high-altitude, inside heat pipe pressure is increased to 5 atmospheric pressure from 4 atmospheric pressure.Conclusion is: increase imbibition material and increase the working medium filling weight in order to quicken to be enabled in middle part, heat pipe hot junction, shine under the temperature in high-altitude, the thermal-collecting tube pressure inside can surpass original pressure of setting and increase to 5 atmospheric pressure from 4 atmospheric pressure and exceed 25%; Be equivalent to reduce winter a day heat-collecting capacity 35% and will prolong two hours without imbibition material heat pipe start-up course.Also have, only 1.5 milliliters of working medium of sticking are still not enough for sorbing material.
