The water inlet chamber is between the small pipe and the large pipe, and the water outlet is inside the small pipe. The first water outlet chamber of two adjacent hot water heat collection units communicates with the last water inlet chamber, and there are installation holes for installing solar heat collection tubes on the large pipe and small pipe respectively, corresponding to the installation holes on the large pipe. There is a vacuum heat collecting tube sealing ring, and a siphon sealing ring is provided in the installation hole corresponding to the small tube, a hot water outlet is provided at the right end of the last small tube, and an exhaust port is provided on the large tube of each water inlet chamber.

In the present invention, the right end of the small tube close to the partition is preferably fixed on the partition, the right end of the small tube close to the right sealing end of the large tube is fixed on the right sealing end of the large tube, and a heat sink is provided on the small tube and the partition at the junction of the small tube and the partition. Water through the hole.

In actual application, the small tube can also be fixed between the connecting strip and the large tube.

Further, in order to achieve heat preservation effect and convenient connection, a casing is arranged around the large pipe, an insulation layer is filled between the casing and the large pipe, and an exhaust sleeve is arranged on the casing, and each exhaust port passes through the exhaust The pipe passes through the exhaust casing, and the exhaust pipe is buried in the insulation layer.

The present invention further defines that at least two installation holes for installing solar heat collection tubes are provided on each of the hot water heat collection units. The daily supply of hot water is ensured.

For the convenience of installation and beautiful use, preferably, the installation holes are evenly distributed on each hot water heat collection unit.

Wherein, preferably, each hot water heat collecting unit is provided with three installation holes for installing solar heat collecting tubes.

In the present invention, according to the connection characteristics of the heat preservation barrel and the solar heat collecting tube in the prior art, it is preferable that the exhaust port is perpendicular to the installation hole. When connected and used, it can be well ensured that the exhaust port is at the top of the large pipe, thereby ensuring the normal use of the exhaust port.

Compared with the prior art, the present invention has the following beneficial effects:

Through the present invention, its structure is simple, because it adopts a plurality of hot water heat collecting units and the design scheme of setting an exhaust port on each hot water heat collecting unit (in other words: the solar heat collecting tubes are first connected in parallel and then Series design scheme) solves the problem of meeting the hot water supply for people's life in the case of insufficient sunlight. Since each hot water heat collecting unit of the present invention is provided with an exhaust port, the solar heat collecting tube is not easy to break or burst.
