Abstract

The utility model provides a deep color single-layer wall solar heating tube, comprising an inner tube and an outer tube, a vacuum layer is arranged between the outer tube and the inner tube, a bracket is arranged on the bottom of the inner tube, the inner tube is deep color tube, and the wall is a single layer. The solar heating tube is made into either black, or blue or deep blue, no need to be plated with film. The wall is made into a single layer to reach low and middle temperature requirement. When the high temperature requirement is required, a wave tube structure can be arranged inside the solar heating tube to increase the temperature over 100 degrees Celsius and to broaden the application range.

Description

Dark individual layer tube wall solar collector pipe

Technical field

The utility model relates to solar energy heat collector, is a kind of dark individual layer tube wall solar collector pipe that is used on the solar thermal collector.

Background technology

All solar collector pipes of selling on the domestic market all are provided with multilayer, make the solar heat-collection tube wall be at least 2 layers, though coating that the position is set is different with angle, all be in order to increase Heat-collecting effect, yet the solar collector pipe complex manufacturing of this structure, cost is higher relatively.How when increasing Heat-collecting effect, particularly enlarging the solar pipe application, further reducing cost, is one of major subjects of this area research.

Summary of the invention

The purpose of this utility model provides a kind of dark individual layer tube wall solar collector pipe, it makes black, blueness or navy blue with solar collector pipe, do not need plated film, making tube wall is individual layer, low temperature requirement in reaching need reach a high temperature when requiring, and structures such as bellows can be installed in solar collector pipe, it can be reached more than 100 ℃, enlarge its range of application.

The utility model is achieved through the following technical solutions for achieving the above object: dark individual layer tube wall solar collector pipe, comprise outer tube and interior pipe, and between outer tube and the interior pipe vacuum layer is set, interior pipe bottom mounting bracket, interior pipe is dark pipe, the tube wall of interior pipe is an individual layer.The pipe thickness of interior pipe is the 1.3-1.35 millimeter.In the cavity that interior pipe forms bellows is installed, the two ends of bellows are connected with flowline with oil inlet pipe respectively.Bellows periphery clad metal cover is provided with conducting strip on the metallic sheath.

The utility model draws through overtesting: at the solar heat-collection tube wall be under the structure of individual layer dark color on Heat-collecting effect and the tube wall Heat-collecting effect of coating identical, manufacturing cost is about the low 10-15% of thermal-collecting tube of sandwich construction than tube wall, and pipe thickness is reduced, this structure can reach middle low temperature requirement, when requiring when reaching a high temperature, the bellows structure of installing in the interior pipe cavity can make more than the heat-conducting oil heating to 100 ℃, enlarge its range of application, can be applicable to heating of house etc.

Description of drawings

Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is A-A section structure for amplifying schematic diagrames in the accompanying drawing 1.

The specific embodiment

1 is outer tube among the figure, the 5th, and interior pipe is a vacuum layer 6 between outer tube 3 and the interior pipe 5.An end shown in Figure 1 is a closed, and the other end is uncovered, and its axial centre is analysed and observe and is the U type.The bottom mounting bracket 7 of interior pipe 5, interior pipe 5 are dark pipes, and the tube wall of interior pipe 5 is individual layers.Described dark color is black, blueness or navy blue.The pipe thickness of interior pipe 5 is 1.3-1.35 millimeters.In order further to enlarge range of application of the present utility model, can in the cavity 4 that interior pipe 5 forms, bellows 2 be installed, the two ends of bellows 2 are connected with flowline 11 with oil inlet pipe 1 respectively.Further program of the utility model is conducting strip 9 to be set on the metallic sheath 10 at the periphery clad metal cover 10 of bellows 2.When the utility model uses, can be connected with known technology and get final product.Among the figure, the 8th, bag.
