Here, the heat collecting tube body preferably has a tubular body shape of any one of oval, square and circular.

In addition, it is effective that the heat conductive tube is in direct contact with the heat collecting tube body.

In addition, it may include a heat transfer plate for connecting the heat collecting tube body and the heat conduction tube to the heat conduction.

In addition, the heat transfer medium is preferably any one of methanol, ethanol, freon, ammonia water, acetone, carbon dioxide gas.

In addition, the outer casing more preferably includes an antioxidant or an ultraviolet stabilizer.

In addition, the sealing cap has a heat collecting pipe coupling portion that is hermetically coupled to both ends of the heat collecting pipe, a casing coupling portion to which the outer casing is hermetically coupled, and a through hole formed at the center thereof; It is more effective that the heat transfer rod is coupled to the through hole formed in the closed cap of one side of the both closed caps, and the check valve is installed in the through hole of the other closed cap.

As a result, the heat collecting performance is improved, and a solar heat collecting cell which is structurally easy to install and handle without limitation of space is provided.

One side of the heat conduction tube 13 is connected to the heat transfer rod 40, and the other side is provided with a vacuum union 13a for injecting the vacuum and the heat transfer medium 17 inside the heat conduction tube 13. The vacuum union 13a is hermetically sealed after injecting the vacuum and the heat transfer medium 17 into the heat conduction tube 13.

In addition, the heat collecting tube 10 has a region between the heat collecting tube main body 11 and the heat conducting tube 13 on the vacuum union 13a side is sealed, and the heat collecting tube main body 11 and the heat conductive tube on the heat transfer rod 40 connection side. The area between the portions 13 is blocked by the blocking plate 13b in which the air flow hole 13c is formed.

The air flow hole 13c of the blocking plate 13b has an outside air flowing into the gap 32a between the heat transfer rod 40 and the through hole 35 of the sealing cap 30 and the heat collecting tube body 11. By entering the space between the heat conduction pipe 13, the air pressure in the space between the heat collecting pipe main body 11 and the heat conduction pipe 13 is relieved, the heat of the heat transfer rod 40 is transmitted to the sealing cap 30 At the same time, the temperature rise efficiency of the heat transfer medium 17 injected into the heat conduction pipe 13 is improved.

The heat collecting tube 10 of such a structure is hermetically coupled to both ends of the heat collecting tube coupling portion 31 of the sealing cap 30 to be described later.
