Description
Technical field
The utility model relates to the empty eccentric heat-tube vacuum heat collecting element of protection that shines of decompression.
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 anhydrous Energy Efficiency Ratio height in the pipe, meet the safe drinking water standard, single tube damages advantage such as in the same old way work.Therefore.Anhydrous solar energy evacuated heat pipe water heater 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 advantages such as working medium.
But during empty the solarization, heat collecting element inside heat pipe temperature can reach 230 ℃, and the saturated vapor pressure of this temperature correspondence 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 empty the solarization by reducing the working medium filling weight, be example with water conservancy project matter: 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 about 3.7 atmospheric pressure of 140 ℃ from about 10 atmospheric pressure of 180 ℃, and inside heat pipe when continuing to be warming up to 180 ℃ from 140 ℃ of about 3.7 atmospheric high-vapor-pressures internal pressure only have about 4 atmospheric pressure.But the internal pressure when the working medium filling weight can not only shine with sky 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 for make empty when shining 230 ℃ internal pressure be no more than 4 atmospheric pressure, then the working medium filling weight is about 1.8 milliliters.Be light-pipe structure even problem is described heat pipe, when work were spent in inclination about 45, the condensed water of cold junction, the circulating water in hot junction added 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 the heat pipe operate as normal, and guarantee the not bombing because of empty solarization of glass heat pipe, must take the empty safeguard measure of shining.
The Chinese invention patent 2009101951003 anti-empty all-glass vacuum heat collector tube elements that shine; disclosed a kind of empty protection all-glass vacuum heat collector tube element that shines; constitute by between vacuum heat collection element absorber and cover glass-tube, controlled heat transfer path being set; controlled heat transfer path is made up 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 at the gravity assisted heat pipe heat collecting element, thereby specific aim is not strong; The original consistency of product of bimetal leaf heating power transducing actuator that it adopts is just bad, restorable ability can reduce again after temperature distortion repeatedly, 20 year possible projected life of operating point settings that its control system of bearing is relevant, control variables input, comparison, transducing and energy are supplied with and the execution function far can not normally effectively be worked because precision is affected 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. inwards arrow sign input side by side 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 the sign place emit heat energy and be supplied to load and be condensed into the cold junction of liquid below under the gravity effect, being back to, in the vaporization of being heated again 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 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 comprehensively from top to bottom 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 is 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 is that thermotube wall has absorbing film, absorbs sunshine and imports as heat energy, connects described thermotube wall with heat transfer device low thermal resistance simultaneously and heat energy is shifted.
Thisly make that heat pipe 1 is in tilted layout, heat energy is imported 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 sky that is used for solar collection element shines protection, because only need minimum a part of heat radiation power---this part heat radiation power is used for guaranteeing empty the solarization when taking place, and the empty peak that shines the initial stage inside heat pipe vapour pressure that protective device begins to work is 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 radiating element volume compact, dependable performance, heat radiation power little, to the venting of vacuum heat-insulating layer less, to absorber to block influence little and can utilize the heat collecting element tail end as the advantage of heat dissipation interface.
Can see that the needed heat radiation power of more little, the described empty solarization protection device of the area of overlapping cold junction is also more little, 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 elements empty shine protective device relatively be fit to be installed on vacuum heat-insulating layer drum-shaped section or; the heat collecting element cover glass tube has necking segment and is to adopt in necking segment to form back assembling inner glass tube, and then draws tail pipe to be called for short the technology of post-tensioning tail pipe to cover glass tube circle envelope.If the round end-blocking that post-tensioning tail pipe technology 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.
