効率を向上させている。B. Prior Art In general, a solar heat collection tube consists of a heat medium pipe 20 through which a heat medium flows, and a heat medium pipe 2, as shown in FIG.
A flat heat collecting plate 21 thermally connected to the
It has a structure in which a holding device is provided inside a transparent outer tube 22 made of glass via a support plate 21a and a bracket 21b, and the inside of this outer tube 22 is kept at a high vacuum, and the inner tube The installed heat collecting plate 21 and outer tube 22
Vacuum insulation is provided between the When solar heat is collected by the heat collecting plate 21 housed in the outer tube 22 and heating the heat medium flowing in the heat medium tube 20 connected to the heat collecting plate 21, the heat collecting plate 21 is heated by the vacuum insulation.
This prevents convection and conduction of heat from the inside to the outside air, improving heat collection efficiency.
ところで、上記形式の太陽熱集熱管は、その外
管２２内の真空度が通常10-4Torr以上の高真空
に保たれ、10-4Torr以下の真空度になると、太
陽熱集熱管の性能が低下するため、製造工程及び
材質、材料に種々の考慮がはらわれている。 By the way, in the solar heat collector tube of the above type, the degree of vacuum inside the outer tube 22 is usually kept at a high vacuum of 10 -4 Torr or more, and when the degree of vacuum becomes less than 10 -4 Torr, the performance of the solar heat collector tube deteriorates. To achieve this, various considerations have been made to the manufacturing process, materials, and materials.
しかし、前述のように製造工程及び材質、材料
を考慮して得られた太陽熱集熱管においても、そ
の構成部材から時間とともに少量のガスが放出さ

つた欠点があつた。そこで、従来、この放出ガス

ことにより気体によつて真空度が低下するのを防
止するものである。 However, as mentioned above, even in solar heat collector tubes obtained by considering the manufacturing process, materials, and materials, a small amount of gas is released from the component parts over time, so the degree of vacuum decreases and the performance deteriorates. I had a lot of flaws. Therefore, in order to adsorb this released gas, a getter 23 is conventionally installed inside the solar heat collection tube as shown in FIG. 8. The getter 23 has a getter material 24 such as barium stored in an annular groove 23a provided on the outer periphery and having one side open. Then, this getter material 24 is heated from the outside of the solar heat collecting tube using a high-frequency heater (not shown), and the getter material 24 is heated and evaporated to form a metal film surface on the inner circumferential surface of the outer tube 22, and is released at this time. This prevents the degree of vacuum from decreasing due to the gas by adsorbing the gas onto the metal film surface.

By fixing the getter 23 by welding or the like, the getter 23
is held in place within the solar collector tube.
ところが、上記方法によつてゲツター２３を支

間がかかるといつた欠点があつた。 However, when the getter 23 is supported by the above method, it becomes necessary to fix the stay 25 to the heat collecting plate 21, for example, by welding, and during this welding operation,
There is a drawback that it is necessary to accurately position the heat collecting plate 21 at a predetermined position in the longitudinal direction and at a predetermined position in the circumferential direction, which is time-consuming.
