Description
Technical field
The present invention relates to the vacuum heat collection element with lever decompression empty sun protection device.
Background technology
Vacuum heat collection pipe arranges vacuum heat-insulating layer between its cover glass tube and inner glass tube, can manufacture and also can provide domestic hot-water's vacuum solar water heater winter.With the solar water heater of heat-pipe vacuum heat collecting pipe manufacture have more in 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.In pipe, anhydrous solar energy evacuated water-both with hot pipe will likely capture the increasing market share.
Adopt 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 ℃, saturated vapor pressure corresponding to this temperature is 28.53 atmospheric pressure, and corresponding working medium filling weight is that working medium volumetric ratio is 1.1% with the ratio of heat pipe volume, and every 1 liter capacity has 11 ml waters.
The pressure of inside heat pipe in the time of can reducing air drying by reducing 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 while continuing to be warming up to 180 ℃ from 140 ℃ approximately 3.7 atmospheric high-vapor-pressures internal pressure only have 4 atmospheric pressure left and right.But internal pressure when working medium filling weight can not be only with air drying sometimes decides.For 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, working medium filling weight is approximately 1.8 milliliters.Even if problem is described heat pipe is light-pipe structure, 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.
In order to meet the normal work of heat pipe, make working medium filling weight/heat pipe plot ratio be greater than 0.2% even 0.3%, and guarantee glass heat pipe not because air drying and bombing must be taked empty sun protection measure.
The anti-air drying all-glass vacuum of Chinese invention patent 2009101951003 heat collector tube element; disclosed a kind of empty sun protection all-glass vacuum heat collector tube element; by controlled heat transfer path being set between vacuum heat collection element absorber and cover glass-tube, form; controlled heat transfer path is comprised of movable heat transfer piece and actuator, it is characterized in that containing the heating power transducing actuator being connected with vacuum heat collection element absorber low thermal resistance.Because this patent is not specially for 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, after temperature distortion repeatedly, restorable ability can reduce again, operating point setting, control variables input, comparison, transducing and the Power supply that its control system of bearing is relevant and carry out function and far can not normally effectively work 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.
In Fig. 2, heat pipe 1 is made by shell and internal working medium.Its operation principle is: heat energy is i.e. arrow marked position input inwards 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 heat pipe cold junction and be arrow side by side outwards marked position emit heat energy and be supplied to and load and be condensed into the cold junction of liquid below being back under Action of Gravity Field, in the vaporization of being again heated of hot junction working medium ..., constantly circulation realizes 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, its cold junction output is the highest can reach 97 watts even higher.
If attempt the heat pipe 1 of Fig. 2 only to input heat energy from below, and do not take heat energy away, heat pipe 1 steam inside is pressed and can sharply be risen.If heat pipe 1 adopts water as working medium and abundant,, when heat pipe 1 temperature reaches 230 ℃, inner maximum pressure can reach 28.53 atmospheric pressure.
If attempted the comprehensively heating take out heat energy from a section of whole heat pipe 1 length 3% of accounting for for example starting from bottom a little more than heat pipe 1 bottom local below from top to bottom of the heat pipe 1 of Fig. 2, only make position that bottom accounts for heat pipe 1 total length 3% forward simultaneously as overlapping cold junction, the vapour pressure of heat pipe 1 inside can drop to the saturated vapor pressure corresponding with the temperature of cold junction below.When for example water is as working medium, keep heat pipe 1 100 ℃ of the temperature of overlapping cold junction below, even if other parts are heated to 230 ℃ above, because the liquid refrigerant of heat pipe 1 inside is all collected in described overlapping cold junction, heat pipe 1 hot junction above except described overlapping cold junction is whole dry owing to having working medium to supplement, and 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, with Thermal Conduction Equipment low thermal resistance, connect described thermotube wall simultaneously and heat energy shifted.
This make that heat pipe 1 is in tilted layout, heat energy is inputted above heat pipe 1 and only with below a bit of design as overlapping cold junction in other occasions, perhaps there is no what meaning, but the empty sun protection for solar collection element, because only need minimum a part of heat radiation power---when this part heat radiation power is used for guaranteeing that air drying occurs, the peak of the initial stage inside heat pipe vapour pressure that empty sun protection device starts to work is no more than setting value; This part heat radiation power is also 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 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 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.Tail box can hide the tail end of heat collecting element.The part being hidden by 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 be relatively applicable to being installed on vacuum heat-insulating layer drum-shaped section or; heat collection element cover glass pipe is with necking segment and be to adopt after necking segment forms, to assemble inner glass tube, 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, with regard to needing to utilize, from described round end-blocking cover glass tube drum-shaped section up, dispel the heat.Heat pipe or the inner glass tube end section corresponding with described drum-shaped section belong to overlapping cold junction.
China's 912050845 utility model electric cooker automatic magnetic temperature detect switch (TDS)s, have introduced a kind of pyromagnetic force inverting element operation principle of utilizing.
