Abstract
The utility model discloses a heat collecting device which comprises more than two heat collecting tubes, and the heat collecting tubes are movably connected with one another. According to the heat collecting device, the heat collecting tubes are connected with one anther movably instead of through welding, and therefore mounting efficiency of the heat collecting tubes is improved greatly. Further, when one heat collecting tube needs to be repaired or changed, the corresponding heat collecting tube can be detached and repaired, then the heat collecting tube can be mounted, therefore, the service life of the heat collecting device is prolonged, and cost is reduced.
Description
Technical field
The utility model relates to a kind of heat collector, relates in particular to a kind of for the heat collector on the solar energy.
Background technology
Heat collector is widely used in the solar energy equipment as a kind of photo-thermal conversion equipment.It can absorb sunlight expeditiously, and the sunlight that absorbs is converted into required heat energy.Present a kind of heat collector comprises the thermal-collecting tube more than two, usually needs thermal-collecting tube is docked with thermal-collecting tube fixing during use.As shown in Figure 1, present a kind of thermal-collecting tube comprises metal inner pipe 2 ', glass outer tube 1 ' and two bellowss 3 '.Be evacuated between interior pipe 2 ' and the outer tube 1 '.Interior pipe 2 ' two ends stretch out in outer tube 1 ' two ends respectively.Outer tube 1 ' is connected by bellows 3 ' with interior pipe 2 ', and interior pipe 2 ' two ends stretch out in bellows 3 ' two ends respectively, to eliminate thermal stress.As shown in Figure 2, when needs connect two thermal-collecting tubes, in two, manage the welding of 2 ' coaxial line ground, and pipe 2 ' forms weld seam 4 ' in two.Fix by the mode of welding between the thermal-collecting tube, need constantly to adjust two thermal-collecting tubes and make pipe 2 ' coaxial line in two, cause installation effectiveness very low; In addition, low by the pressure limit that fixedly can bear of mode of welding, when running into strong external impacts, be easy to cause connection to come off; Moreover, when a thermal-collecting tube damages, often cause whole heat collector to scrap.
The utility model content
One of the purpose of this utility model is in order to overcome deficiency of the prior art, a kind of bonding strength that can strengthen between the thermal-collecting tube to be provided, and improves the heat collector of installation effectiveness.
For realizing above purpose, the utility model is achieved through the following technical solutions:
A kind of heat collector comprises the thermal-collecting tube more than two, connects versatilely between the plural described thermal-collecting tube.
Preferably, described thermal-collecting tube two ends offer external screw thread, are threaded between the plural described thermal-collecting tube.
Preferably, also comprise connector, described connector runs through and offers through hole, and described through-hole wall two ends offer internal thread, are fixedly connected on the described connector by described external screw thread and described screw-internal thread fit between the plural described thermal-collecting tube.
Preferably, described thermal-collecting tube comprises outer tube, interior pipe and two tube connectors, described interior pipe is arranged in the described outer tube and its two ends stretch out in described outer tube two ends, and described outer tube is connected by described tube connector with interior pipe, and described interior pipe two ends stretch out in described tube connector two ends respectively.
Preferably, described internal thread is opened in described interior pipe two ends.
The utility model heat collector by connect replacing welding of the prior art between the thermal-collecting tube versatilely, having improved installation effectiveness between the thermal-collecting tube greatly, having improved the intensity that connects; In addition, when one of them thermal-collecting tube need keep in repair or change, install again after only need pulling down corresponding thermal-collecting tube maintenance, improved heat collector service life, reduced cost.

Fig. 2 is the welding schematic diagram between the thermal-collecting tube of the heat collector among Fig. 1.
Fig. 3 is the structural representation of the thermal-collecting tube of the utility model heat collector.
Fig. 4 is the connection diagram of the thermal-collecting tube of the utility model heat collector.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 3 and Figure 4: heat collector comprises thermal-collecting tube 1 and connector 2 more than two.Two thermal-collecting tubes 1 are connected and fixed by connector 2.
Thermal-collecting tube 1 comprises outer tube 11, interior pipe 12 and two tube connectors 13.Outer tube 11 is the glass outer tube.Interior pipe 12 is metal inner pipe.Tube connector 13 is bellows.Interior pipe 12 is arranged in the outer tube 11 and its two ends stretch out in outer tube 11 two ends.Outer tube 11 is connected by tube connector 13 with interior pipe 12.Interior pipe 12 two ends stretch out in tube connector 13 two ends respectively.External screw thread 14 has been attacked at the two ends of interior pipe 12.
Connector 2 runs through and offers through hole 22.Through hole 22 inwall two ends offer internal thread 21.In pipe 12 cooperate with internal thread 21 by external screw thread 14 and to be fixedly connected on the connector 2.Connector 2 two ends by the interior pipe 12 that is threaded, can be connected and fixed two thermal-collecting tubes 1 respectively.
Connector 2 in the present embodiment is non-essential.Can then two thermal-collecting tubes 1 directly be threaded by respectively two thermal-collecting tubes, 1 two ends to be connected being offered internal thread and the external screw thread of working in coordination respectively.
The utility model heat collector can also replace by other means and is threaded, and two thermal-collecting tubes 1 are connected versatilely.
The utility model heat collector replaces welding of the prior art by connecting versatilely between the thermal-collecting tube, has improved installation effectiveness between the thermal-collecting tube greatly, has improved the intensity that connects; In addition, when one of them thermal-collecting tube need keep in repair or change, install again after only need pulling down corresponding thermal-collecting tube maintenance, improved the service life of heat collector and reduced cost.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
