In conjunction with shown in Fig. 1 to Fig. 4, a kind of coil pipe honeycomb cavate liquid working substance solar thermal collector in the present embodiment, including
It is provided with the attemperator of sun optical entrance, the heat sink being set in the babinet of attemperator 2 and and heat sink
2 are connected flows to the guiding device 3 of surrounding for heat transfer medium from the middle part of heat sink 2；Heat sink 2 is to be distributed in heat preservation
The 4*4 collection hot coils 21 in hollow cylinder setting in device box；Guiding device 3 includes main flow pipe, and is symmetrically set
It is placed in the Zhi Liuguan of main flow pipe both sides, Zhi Liuguan is connected with the input terminal of collection hot coil 21 and output end respectively.
Specifically, in conjunction with shown in Fig. 3, collection hot coil 21 in the present embodiment by 2 211 parallel spiral windings of thermal-collecting tube and
At the end of 2 thermal-collecting tubes 211 is separately provided for be connected with Zhi Liuguan 4 the first joint flanges 212,4 first
Joint flange 212 is located at the same end of collection hot coil 21, and is provided between adjacent thermal-collecting tube 211 for compensating thermal-collecting tube
The gap of 211 thermal deformation surpluses.The collection hot coil designed by this method, two thermal-collecting tubes, four ports after parallel spiral winding
Equal bending is in the same end of collection hot coil 21, later, as shown in fig. 7,4*4 collection hot coil 21 is equal in length and breadth by supporting rack 6
In cloth to vaccum case 11, and so that one end of port is towards 11 inner bottom surface side of vaccum case there are four collection 21 bendings of hot coil
To setting, and make each port is penetrated through by the first joint flange 212 with the Zhi Liuguan on guiding device to connect.It sets by this method
It sets, the cover of earthbound solar energy lens group can be passed through so that the heating fused salt in collection hot coil effectively absorbs heat, and by leading
Heat is exported by heating fused salt, heating fused salt after cooling is re-poured into collection hot coil again later by the effect for flowing device,
It recycles and steam boiler is heated according to this endlessly.
In the present embodiment, in conjunction with shown in Fig. 2, guiding device 3 further includes vertically through setting with main flow pipe into flow tube 33
With outflow tube 34, it is connected into flow tube 33 and outflow tube 34 with external device (ED) through attemperator.Main flow pipe includes laterally being arranged
In into 33 lower end of flow tube the first main flow pipe 311, be set to the lower section of the first main flow pipe 311 and parallel with the first main flow pipe 311 set
The second main flow pipe 312 for setting, is horizontally set at the third main flow pipe 313 being longitudinally disposed above 312 both ends of the second main flow pipe
The 4th main flow pipe 314 above three main flow pipes, 313 both ends and be longitudinally disposed between adjacent 4th main flow pipe 314 the 5th
Main flow pipe 315, the 5th main flow pipe 315 is arranged in shape of chinese word Ji, and the middle part of the 5th main flow pipe 315 is vertically installed with outflow tube 34.
It is evenly equipped with the Zhi Liuguan 32 of inverted u-shaped, Zhi Liuguan 32 respectively along the length direction of the second main flow pipe 312 and third main flow pipe 313
End set be useful for and 212 matched second joint flange 321 of the first joint flange.With this structure design, Neng Goufang
Just efficient to be flowed into and out successively along multiple collection hot coils so that heating fused salt, and then circulate, progress heat rapidly and efficiently
The collection and transmission of amount.
In the present embodiment, in earthbound solar energy lens group through the sun optical entrance on vaccum case 11 to multiple collection hot plates
When pipe 21 is irradiated, since the collection hot coil daylighting area positioned at middle part is larger, and positioned at the collection of middle part collection hot coil surrounding
Hot coil daylighting area is relatively small, therefore the temperature for heating fused salt flowed into order to prevent in the collection hot coil of middle part is excessively high, right
Collection hot coil causes to damage, and the most use for flowing through guiding device of fused salt is heated in the present embodiment, using " first four behind middle part
The mode in week " is flowed, with this balanced temperature for collecting the heating fused salt in hot coil everywhere, therefore using the above scheme to water conservancy diversion
Device is designed, with this so that the lower heating fused salt of temperature by flowing simultaneously into flow tube, the first main flow pipe 311 and Zhi Liuguan
Enter in the four collection hot coils in middle part, later again by being flowed into and four, middle part thermal-arrest after Zhi Liuguan and the outflow of the second main flow pipe 312
In four collection hot coils of coil pipe the right and left, later again by flowing into 4*4 thermal-arrest after Zhi Liuguan and the outflow of third main flow pipe
The quadrangle of coil pipe, then again by flowing into the four of the four collection hot coils in middle part or more both sides after Zhi Liuguan and the outflow of the 4th main flow pipe
In a collection hot coil, is flowed out finally by the outflow tube 34 at 315 middle part of the 5th main flow pipe, complete following successively for heating fused salt according to this
Circulation is dynamic.
It is located at the heat losses that the heat sink at 11 middle part of vaccum case is absorbed into order to prevent, prevents heating fused salt because of temperature
Difference causes to cure, and sealing cover is additionally provided at the sun optical entrance of attemperator in the present embodiment, when avoiding no light, melts
Salt is quickly cooled down.
In addition as shown in Figures 4 to 6, the attemperator in the present embodiment includes vaccum case 11, is coated on vaccum case
11 periphery and with the outer housing 13 of 11 gap setting of vaccum case and the guarantor being filled between outer housing 13 and vaccum case 11
Warm layer 12, if vaccum case 11 is made of dry plate evacuated panel 111, evacuated panel 111 is anti-including the first radiation proof board 1111 and second
Radiant panel 1112, and it is located in the first net between the first radiation proof board 1111 and the second radiation proof board 1112 in vacuum cavity
Shape holder 1113 is provided with the second network 14 between insulating layer 12 and outer housing 13.With this structure design, in addition to that can make
Obtaining the attemperator has certain structural strength, simultaneously, additionally it is possible to by the setting of vaccum case and insulating layer, with external world's temperature
Degree is formed and is effectively isolated, and then plays good heat insulation effect to the heat sink in vaccum case, avoids the loss of heat.
The generation of the abnormal conditions such as heating fused salt spill and leakage in order to prevent, pollutes attemperator, in the present embodiment,
Leakproof storage box 8 is provided in the babinet of attemperator, leakproof storage box 8 is located at the lower section of heat sink 2 and guiding device 3.
Spill and leakage can effectively collect heating fused salt, be prevented excessive everywhere with this.
