Description
Technical field
The present invention relates to the low solar energy heat collector putting short cylinder wick of heat collecting element glass heat pipe.
Background technology
The solar water appliance of heat-pipe vacuum heat collecting pipe manufacture has in pipe the advantages such as anhydrous Energy Efficiency Ratio is high, meet safe drinking water standard, single tube damage works in the same old way. Therefore. In pipe, anhydrous solar vacuum hot water device is it would be possible to capture the increasing market share.
Existing a kind of workload fills little all-glass heat pipe vacuum collector tube solar water heater, and heat pipe inner wall adopts light-pipe structure, heat-pipe vacuum heat collecting pipe to tilt about 45 degree of installations. Under non-heat exchange state, it can be observed that have liquid refrigerant to gather bottom heat pipe.
It is carried out and the all-glass vacuum thermal-collecting tube solar water heater controlled trial of water in pipe, it has been found that the ramp case of heat pipe solar energy water heater is first slow rear fast. Judgement is that heat pipe start-up course is long, heat pipe startup stage, heat collector tube product can not Operation at full power thus heat up slow, heat pipe start after heat pipe heat collecting device Operation at full power thus quick heating.
The heat pipe investigating all-glass heat pipe vacuum collector tube starts: owing to being collected in the working medium bottom heat pipe usually because its temperature of minute surface shading formed by getter rises slowly so that these liquid refrigerants can not participate in rapidly two phase flow heat transfer circulation. Though simultaneously as the temperature at other positions internal, heat pipe hot junction is high but being in dry state within a very long time and thermal-arrest can not be contributed. Relying on the glass heat pipe tube wall heat transfer near bottom make liquid refrigerant vaporize gradually and circulate participation two phase flow heat transfer, heat pipe completes start-up course and enters normal operating conditions later. Problem is in the winter time, and the start-up course of heat pipe is likely to continue more than two hours, and this makes the performance of some glass heat pipe thermal-collecting tube can not be substantially good than the all-glass vacuum thermal-collecting tube of the interior water of pipe, and the advantage of heat pipe could not give full play to.
Glass surface is not suitable for processing stria to form bigger capillary lift.
Adopt and arrange that there is enough large-area core net at glass heat pipe inner surface, although available capillarity solves the problem that heat pipe start-up course is long, but cost a larger increase can be made, more seriously also can fill that working medium is more because of inside, vapour pressure is too high and cause the risk of bombing accident to be greatly increased when making air drying. Such as 0.2% when working medium filling weight/heat pipe volume rate is from 2 milliliters/1000 milliliters brings up to 0.5% when 5 milliliters/1000 milliliters, the highest saturated vapor pressure increases about 10 atmospheric pressure to 180 DEG C from about 3.7 atmospheric pressure of 140 DEG C, but inside heat pipe from 140 DEG C about 3.7 atmospheric most high-vapor-pressures be continuously heating to 180 DEG C time internal pressure only have 4 atm higher. Owing to glass pressure is limited in one's ability, so, should manage to raise liquid refrigerant position height start quickly when heat pipe starts, the least possible when heat pipe works again retain liquid refrigerant to reduce working medium filling weight.
Chinese invention patent 200410012193.9 Explosion-proof all-glass solar energy vacuum collecting tube, discloses a kind of Explosion-proof all-glass solar energy vacuum collecting tube, and in its heat pipe, liquid refrigerant filling weight is 0.1～0.5%V, and wherein V is the volume in heat pipe. Being completely converted into vapour phase when reaching a certain critical temperature, when temperature continues to raise, pressure raises according to the rule of vapour phase, thus the operating pressure significantly reduced under the condition of high temperature in heat pipe .... Meanwhile, heat pipe is set up adsorbing material, to ensure that heat pipe quick starts again. But the adsorbing material sticking working medium that this patent of invention is arranged in the middle part of heat pipe includes heat pipe evaporator section adds quick heating pipe and starts this mode and still can bring and increase working medium filling weight and internal pressure or start still slower problem during air drying. Assuming that: the internal pressure upper limit of the all-glass vacuum solar energy collection tube originally setting inner glass tube internal diameter 4.4 millimeters, cover glass tube external diameter 58 millimeters, length 2 meters makes working medium as 4 atmospheric pressure, air drying maximum temperature 230 DEG C, water, can be calculated inner glass tube volume about 3 liters. The saturated vapor pressure table looking into water vapour is known: the working medium filling weight of just all working medium vaporizations when 135 DEG C, its saturated vapor pressure is 3.2 atmospheric pressure and when the highest air drying temperature 230 DEG C, and internal pressure reaches 4 atmospheric pressure namely equal to the inner glass tube internal pressure limit. And the quality volumetric ratio that can check in steam when 135 DEG C is 1.7 ml l. The working medium filling weight of this thermal-collecting tube is 3 liter of * 1.7 ml l=5.1 milliliter. (5.1 milliliters of working medium, on the low side existing thermal-collecting tube, there will be dry in bottom, hot junction, but this problem do not done here and launched). Now, imbibition material is set in the middle part of inside heat pipe in order to add quick heating pipe startup. Assuming that the imbibition material increased carries sticking when heat pipe normal operation 1.5 milliliters of working medium altogether, and therefore aggravating inside heat pipe hot junction dry-out, dry hot junction is not involved in heat exchange makes the efficiency of thermal-collecting tube have a greatly reduced quality. In order to avoid because of hot junction dry up bring heat-collecting capacity loss. Put forward, by imbibition material, the part working medium that sticking has when must increase working medium filling weight to make up heat pipe work. Assume that the working medium filling weight increased also is 1.5 milliliters, then the quality volumetric ratio of steam when working medium is just all vaporized rises to 2.2 ml l from 1.7 ml l, and the critical temperature that the highest saturated vapor pressure at this moment is corresponding rises to 145 DEG C from 135 DEG C; Correspondingly, when the highest air drying temperature 230 DEG C, inside heat pipe pressure increases to 5 atmospheric pressure from 4 atmospheric pressure.It is concluded that increase imbibition material in the middle part of heat pipe hot junction to accelerate to start and increase working medium filling weight, at the highest air drying temperature, the pressure within thermal-collecting tube can exceed the pressure of original setting to be increased to 5 atmospheric pressure beyond 25% from 4 atmospheric pressure; To extend two hours without imbibition material heat pipe start-up course and be equivalent to and reduce day heat-collecting capacity 35% winter. Further, only 1.5 milliliters of working medium of sticking are still not enough for adsorbing material.
