[0012] Further, the inner container body is provided with detachable end covers blocking the passages at both ends, the end covers are provided with openings in communication with each single passage, and the end covers are provided with connecting heads in communication with the openings at outer ends.

[0013] Further, the inner heat-conducting pipe and the outer heat-conducting pipe are concentrically arranged.

[0014] Further, the shell is arranged on the periphery of the inner container body, the heat preservation layer is arranged between the shell and the inner container body, the tail frame is arranged, and the heat collecting pipe is arranged between the tail frame and the shell.

[0015] The heat collecting pipe is sleeved outside the outer heat conducting pipe and arranged at one end of the tail frame and the other end of the shell.

[0016] Further, the outer heat conducting pipe and the inner heat conducting pipe are fixed in a detachable manner, and sealing rings are arranged at the connecting positions.

[0024] 1. The inner channel and the outer channel are arranged, the heat conducting medium can flow between the outer channel, the outer heat conducting pipe, the inner heat conducting pipe and the inner channel, the flowability of the heat conducting medium is improved, and the heat exchange efficiency is improved.

[0025] 2. The heat conducting medium does not directly contact the heat collecting pipe, and the condition that when the heat collecting pipe directly contains the heat conducting medium, one heat collecting pipe is damaged and the medium is completely lost is avoided.

[0026] 3. The heat conducting medium does not flow in the heat collecting pipe, so that the condition that the temperature difference between the inside and the outside of the heat collecting pipe instantaneously increases is reduced, and the risk of pipe explosion is reduced.

[0027] 4, the heat collecting tube of the traditional header needs to extend into the inner container and is usually sealed and connected by punching metal and clamping silica gel ring, which is very inconvenient for plugging. In the application, there is no heat conducting medium in the heat collecting tube, both ends do not need to extend into the inner container and the sealing requirement is low, so it is more convenient to plug.

[0028] 5, the inner container body in the prior art is generally sealed by welding, which makes the header inner container difficult to manufacture, cannot be disassembled and is inconvenient to clean and maintain. The inner container body of the application is provided in the form of a detachable end cover, which is more convenient to disassemble and maintain.

[0029] 6, according to different use modes, the application can be applied to various arrangement forms of one-way vertical insertion pipe and two-way horizontal insertion pipe.

[0030] 7, the size of the heat conducting pipe assembly is generally smaller than that of the heat collecting tube, and compared with directly containing heat conducting medium in the existing heat collecting tube, the amount of medium is relatively small.

[0031] 8, in the prior art, the heat conducting medium flows naturally by heat exchange, and in order to realize emptying, the header can only be placed vertically, and the heat collecting tube is inserted horizontally. Since the header cannot be placed horizontally, during installation, especially in rural sharp roof houses, the installation pipe is long, heat preservation is difficult, and materials and labor are wasted. The application is different, and appropriate installation mode can be selected according to actual conditions.

[0032] 9, suitable for various scenes of household and industrial and commercial solar heat collection and later development. BRIEF DESCRIPTION OF DRAWINGS
