Description
Technical field
The utility model relates to solar energy heat utilization field, relates in particular to the heat pipe that a kind of solar thermal collector is used.
Background technology
Heat pipe is to realize that heat transmits fast and the ideal chose of exchange.Heat pipe is realized High Efficiency Thermal conduction, exchange by phase transformation, utilizes the evaporation of airtight cavity internal working medium, condensation phase transformation to carry out the heat transmission, and its heat-transfer capability is that tens of traditional metal materials arrives hundreds of times.Hot pipe technique is applied in solar energy heating technical, obtains heat pipe type solar heat collection pipe.This thermal-collecting tube generally is to be welded with the heat pipe of coating for selective absorption fin as heat-absorbing plate core, this coating for selective absorption can absorb sunshine to greatest extent, then be converted into heat energy, and minimizing thermal radiation loss that can be as far as possible little, so collecting efficiency is very high.Simultaneously, this heat pipe type solar heat collection pipe thermal shock is little, reduced all the time according to the time system reverse heat waste, and the heat loss of supreme lower circulation line.Present this thermal-collecting tube not only can provide the domestic hot-water, also is used for simultaneously the fields such as steam turbine power generation and accumulation of energy.Therefore hot pipe type vacuum heat collection pipe has represented the new developing direction of heat collector.
The heat pipe of at present extensive use on solar thermal collector, its condensation segment is generally thick than evaporator section, can increase like this heat exchange area between condensation segment and the comb.Yet, because evaporator section is not identical with the condensation segment diameter, cause in the process of preparation, condensation segment will be first by reducing, make its bore identical with evaporator section, and then by the method for welding evaporator section and condensation segment are welded, this preparation method is quite loaded down with trivial details; If adopt the condensation segment structural design identical with the evaporator section diameter, so, directly copper pipe is vacuumized the filling liquid sealing and just can obtain the copper heat pipe.Yet this design will inevitably so that the heat exchange area of condensation segment reduce.Increase the area of the condensation segment of this structure heat pipe, the most direct method is exactly the length that prolongs condensation segment on the basis that does not increase diameter, and it is thicker that this inevitable requirement comb is done, and increased again system cost.
Summary of the invention
The utility model had both been simplified the preparation method of heat pipe condenser section and evaporator section for the deficiencies in the prior art, can effectively guarantee again the heat exchange area between condensation segment and the comb.
For achieving the above object, the utility model is taked following technical scheme:
The heat pipe that a kind of solar thermal collector is used comprises evaporator section and condensation segment, and the caliber of evaporator section and condensation segment is identical, and condensation segment is bending or helical form.
With the metal tube of designated length and diameter, an end reducing sealed, then other end reducing vacuumizes, and the most backwardly wherein pours into working medium, sealing, obtains initial heat pipe.Calculate the heat exchange area of needs according to the heat exchange needs, and then determine the length of condensation segment, with bending machine with it crooked or with screw machine with its spiral, obtaining condensation segment is bending or spiral helicine heat pipe.Above-mentioned heat pipe has omitted reducing and welding procedure on the one hand, has simplified existing manufacture craft; On the other hand, the condenser pipe design of bending or spiral also can not reduce the heat exchange area between condensation segment and comb.
Have the fin of selective absorption in the evaporator section welding of above-mentioned heat pipe, then carry out sealing-in with glass tube, glass tube vacuumizes, and has just obtained hot pipe type vacuum heat collection pipe.Because the condensation segment of this hot pipe type vacuum heat collection pipe is crooked or spiral, therefore, this hot pipe type vacuum heat collection pipe can insert in the comb smoothly along the angle of condensation segment bending or spiral.Wherein the angle of bend between condensation segment and the evaporator section is less than 90 °; The shell of heat pipe can be metallic copper, aluminium, titanium and stainless any, and what the working medium of heat pipe can be in water, ethanol, methyl alcohol, liquefied ammonia, acetone, hexane and the toluene is any.
The utility model is simple in structure, cost is low, easy to make, also very simple with its manufacture craft of making heat pipe solar vacuum heat-collecting pipe.

Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
The specific embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
Embodiment 1
As shown in Figure 1, it is the metal tube of 12mm with diameter that the present embodiment is 1 meter with length, an end reducing sealed, and then other end reducing vacuumizes, the most backward working medium of wherein pouring into, sealing obtains initial heat pipe.At distance heat pipe end points 10cm place, with its bending, obtaining condensation segment is forniciform heat pipe with bending machine.The condensation segment of heat pipe and the angle of bend θ between the evaporator section are 10 °, 45 ° or 85 °.
Embodiment 2
As shown in Figure 2, the condensation segment of the present embodiment is that the condensation segment of spiral helicine heat pipe preparation method and embodiment 1 is that forniciform heat pipe preparation method is identical, and difference is, obtains with screw machine condensation segment being done curl after the initial heat pipe.
Need to prove, the shell of heat pipe can be metallic copper, aluminium, titanium and stainless any among the embodiment, and what the working medium of heat pipe can be in water, ethanol, methyl alcohol, liquefied ammonia, acetone, hexane and the toluene is any.
