Description
Technical field
The utility model relates to decompression empty sun protection metal heat pipe vacuous solar energy heat collector.
Background technology
Vacuum heat collection pipe arranges vacuum heat-insulating layer between its cover glass tube and inner glass tube, can make the vacuum solar water heater that also can provide the domestic hot-water winter.With the solar water heater of heat-pipe vacuum heat collecting pipe manufacturing have more in the pipe anhydrous Energy Efficiency Ratio high, meet safe drinking water standard, single tube and damage the advantage such as in the same old way work.Therefore.Anhydrous solar energy evacuated water-both with hot pipe might capture the increasing market share in the pipe.
Adopt the integrated glass heat pipe have can with cover glass tube melt envelope, glass heat pipe surface can directly make absorbing film heat transfer link few, can adopt the splendid water of thermophysical property to make the advantages such as working medium.
But during air drying, heat collecting element inside heat pipe temperature can reach 230 ℃, and saturated vapor pressure corresponding to this temperature is 28.53 atmospheric pressure, and corresponding working medium filling weight is that the working medium volumetric ratio is 1.1% with the ratio of heat pipe volume, and namely per 1 liter capacity has 11 ml waters.
The pressure of inside heat pipe in the time of can reducing air drying by reducing the working medium filling weight, take device of working medium as example: when working medium filling weight/heat pipe plot ratio 0.5% during from 5 milliliters/1000 milliliters are reduced to 2 milliliters/1000 milliliters 0.2%, correspondingly its highest saturated vapor pressure is reduced to approximately 3.7 atmospheric pressure of 140 ℃ from approximately 10 atmospheric pressure of 180 ℃, and inside heat pipe when approximately 3.7 atmospheric high-vapor-pressures continue to be warming up to 180 ℃ from 140 ℃ internal pressure only have about 4 atmospheric pressure.But the internal pressure when the working medium filling weight can not be only with air drying sometimes decides.For a working medium filling weight/heat pipe plot ratio be 0.2%, the heat pipe of 1000 milliliters of internal capacities, 2000 millimeters of length, if internal pressure is no more than 4 atmospheric pressure when making 230 ℃ of air dryings, then the working medium filling weight is approximately 1.8 milliliters.Be light-pipe structure even problem is described heat pipe, when tilting approximately 45 degree work, the condensed water of cold junction, the circulating water in hot junction add that 0.353 milliliter of sum of the water yield of 85 ℃ of water vapours can be far away from 1.8 milliliters.
Make working medium filling weight/heat pipe plot ratio greater than 0.2% even 0.3% in order to satisfy heat pipe normal operation, and guarantee glass heat pipe not because air drying and bombing must be taked the empty sun protection measure.
Chinese invention patent 2009101951003 anti-air drying all-glass vacuum heat collector tube elements; disclosed a kind of empty sun protection all-glass vacuum heat collector tube element; consist of by between vacuum heat collection element absorber and cover glass-tube, controlled heat transfer path being set; controlled heat transfer path is comprised of movable heat transfer piece and actuator, it is characterized in that containing the heating power transducing actuator that is connected with vacuum heat collection element absorber low thermal resistance.Because this patent is not specially for the gravity assisted heat pipe heat collecting element, thereby specific aim is not strong; The uniformity of the original product of bimetal leaf heating power transducing actuator that it adopts is just bad, restorable ability can reduce again after temperature distortion repeatedly, and operating point settings, control variables input, comparison, transducing and the Power supply that its control system of bearing is relevant and execution function far can not normally effectively be worked because precision is affected 20 year possible projected life of heat collecting element.
Fig. 2 provides the light-pipe structure gravity assisted heat pipe structural representation of a tiltably-mounted.
Among Fig. 2, heat pipe 1 is made by shell and internal working medium.Its operation principle is: heat energy is i.e. side by side inwards arrow marked position input from the hot junction of below, make the vaporization of being heated of the working medium at heat pipe 1 inner bottom place, steam is under the effect of pressure reduction, upwards advance to the heat pipe cold junction and be arrow side by side outwards marked position emit heat energy and be supplied to load and be condensed into the cold junction of liquid below under Action of Gravity Field, being back to, in the vaporization of again being heated of hot junction working medium ..., constantly circulation realizes the two phase flow heat transfer circulation thus.Heat pipe has excellent heat-transfer capability, heat flow density ability to transform and isothermal characteristics.If 100 watts of heat pipe 1 hot junction inputs, then its cold junction output is the highest can reach 97 watts even higher.
If attempt heat pipe 1 to Fig. 2 only from following input heat energy, and do not take heat energy away, then heat pipe 1 steam inside is pressed and can sharply be risen.If heat pipe 1 adopts water as working medium and abundant, then when heat pipe 1 temperature reached 230 ℃, inner maximum pressure can reach 28.53 atmospheric pressure.
If attempt the from top to bottom comprehensively heating and take out heat energy from following a section of whole heat pipe 1 length 3% of accounting for that for example begins from the bottom a little more than heat pipe 1 bottom local of the heat pipe 1 of Fig. 2, namely only make position that the bottom accounts for heat pipe 1 total length 3% forward simultaneously as overlapping cold junction, then the vapour pressure of heat pipe 1 inside can drop to the saturated vapor pressure corresponding with the temperature of following cold junction.When for example water is as working medium, 100 ℃ of the temperature of maintenance heat pipe 1 following overlapping cold junction, even then top other parts are heated to 230 ℃, because the liquid refrigerant of heat pipe 1 inside all is collected in described overlapping cold junction, heat pipe 1 hot junction above except described overlapping cold junction is not owing to there being working medium to replenish whole drying up, and the two phase flow heat transfer mechanism has not existed.The steam pressure of heat pipe 1 inside 1 atmospheric pressure of also only having an appointment.
An example of overlapping cold junction be thermotube wall with absorbing film, absorb sunshine and input as heat energy, connect described thermotube wall with the Thermal Conduction Equipment low thermal resistance simultaneously and heat energy shifted.
Thisly make that heat pipe 1 is in tilted layout, heat energy is inputted and only perhaps do not had what meaning with following a bit of design as overlapping cold junction in other occasions above heat pipe 1, but the empty sun protection that is used for solar collection element, because only need minimum a part of heat radiation power---when this part heat radiation power was used for guaranteeing that air drying occurs, the peak of the initial stage inside heat pipe vapour pressure that the empty sun protection device begins to work was no more than setting value; This part heat radiation power also is greater than described overlapping cold junction as the heat energy input power in hot junction---thus have advantages of radiating element volume compact, dependable performance, heat radiation power little, on the venting of vacuum heat-insulating layer less, on absorber to block impact little and can utilize the heat collecting element tail end as heat dissipation interface.
Can see, the needed heat radiation power of less, the described empty sun protection device of the area of overlapping cold junction is also less, more favourable.Actual heat collecting element needs the device of tail box and so on to settle.The tail box can hide the tail end of heat collecting element.The part that is hidden by the tail box does not belong to overlapping cold junction.Why also can use overlapping cold junction; be because some heat collecting element empty sun protection device relatively be fit to be installed on vacuum heat-insulating layer drum-shaped section or; heat collection element cover glass pipe is with necking segment and be to adopt to assemble inner glass tube after necking segment forms, and then draws tail pipe to be called for short the technique of post-tensioning tail pipe to cover glass tube circle envelope.If the round end-blocking that post-tensioning tail pipe technique forms is not suitable for heat radiation, dispel the heat from described round end-blocking cover glass tube drum-shaped section up with regard to needing to utilize.Heat pipe or the inner glass tube end section corresponding with described drum-shaped section belong to overlapping cold junction.
