ようにしたものである。[Means for Solving the Problems] As shown in FIGS. 1 and 2, the present invention provides (1) a heat pipe container with a container body 20 and a lid 2 having the same outer diameter and wall thickness.
(2) in a vacuum atmosphere, after injecting the working fluid 26 into the main body 20, the lid 28 is placed over the container main body 20 and abutted; (j) the abutting surface 30 is heated by high-frequency induction heating; It is designed so that it can be press-fitted.
［実施例］
第１図において、
２０は真空容器（ペルジャー）、
２２はヒートパイプの容器本体で、真空容器２０内に直
立させる。２４は冷却ジャケットである。[Example] In FIG. 1, 20 is a vacuum container (Pel jar), and 22 is a container body of a heat pipe, which is stood upright in the vacuum container 20. 24 is a cooling jacket.
真空容器２０内を真空引きしてから、容器本体２２内に
作動液２６（液状ナトリウム）を注入する。After the vacuum container 20 is evacuated, a working fluid 26 (liquid sodium) is injected into the container body 22.
それから第２図のように、めくら蓋２８をして容器本体
２２と突合わせる。３０は突合わせ面を示す、なお、容
器本体２２と蓋２８とは、突合わせたとき、内外面が一
致するように、それぞれの内外径が等しくしである。Then, as shown in FIG. 2, the blind lid 28 is put on and butted against the container body 22. Reference numeral 30 indicates a mating surface. Note that the container body 22 and the lid 28 have equal inner and outer diameters so that their inner and outer surfaces coincide when they are butted.
突合わせ面３０の周囲に高周波誘導コイル３２を設け、
これにより、真空中において加熱する。A high frequency induction coil 32 is provided around the abutting surface 30,
This causes heating in a vacuum.
そのとき同時に、たとえばエアーシリンダ３４などによ
り突合わせ面３０に圧力を加え、容器本体２２と蓋２８
とを圧接する。At the same time, pressure is applied to the abutting surface 30 by, for example, an air cylinder 34, and the container body 22 and lid 28 are
Press them together.
なお、突合わせ面３０はオリジナルのままにしておく場
合と、高い導電性のセラミックパウダーまたはメタルパ
ウダーをペースト状のバインダで被覆する場合とがある
。Note that the abutment surface 30 may be left as it is, or may be coated with highly conductive ceramic powder or metal powder with a paste-like binder.
なおまた、高周波誘導加熱するためには、蓋２８、容器
本体２２は導電性または半導電性であることが必要であ
る。Furthermore, in order to perform high frequency induction heating, the lid 28 and the container body 22 need to be conductive or semiconductive.
炭化ケイ素、酸化チタン、ジルコニア、β−アルミナな
どは、それに適合する。Silicon carbide, titanium oxide, zirconia, β-alumina, etc. are suitable.
［発明の効果］
（１）すべてセラミックスなので、限界使用温度が上が
り、また耐食性も良い。[Effects of the invention] (1) Since it is made entirely of ceramics, the limit service temperature is increased and corrosion resistance is also good.
（２）真空中ですべての工程を行うので、作動液のとり
扱いが容易になる。(2) Since all processes are performed in a vacuum, handling of the hydraulic fluid becomes easier.
（３）ノズルを作る必要がない。(3) There is no need to make a nozzle.
（４）高周波誘導加熱であるから、真空を悪化させない
。(4) Since it is high frequency induction heating, it does not deteriorate the vacuum.
