ができるように決められる。The shape of the stopper (lll) may be a simple flat cylindrical shape as shown in the cut section, but it is preferable to have a shape tapered at the tip side as shown in Figure 1 (A), as this will facilitate insertion as described below. Furthermore, when the material is hard, such as hard rubber, the injection needle insertion point (f' ) should be shaped so that the thickness <S> of the heat pipe body (1) is small.Also, considering the sealing performance with the inner surface of the heat pipe body (1),
If it is made of hard rubber, it is recommended to cover the surface with soft rubber. If the material is soft, such as soft rubber,
It is also effective to take measures such as incorporating a reinforcing ring (6) to increase the rigidity, as shown in (A) (cross-sectional view) and (B) (plan view) in Figure (C). A stopper like this (4
The outer diameter (D/) of the IJ is determined in consideration of the inner diameter (D) of the main body (1) of the heat pie 1 so that it can be tightly fitted into the main body (1).

7) is inserted so that it reaches the internal space (A) of the main body. The thickness of the injection needle (5) should be as thin as possible, but it is also desirable to have a diameter of 3M or less, considering workability. If you use one that is too thick, there is a risk that a hole will form in the stopper (lIl) after it is removed, impairing its function as a stopper. However, it is more advantageous to insert the injection needle T51 into the state shown in Fig. (B) and then press fit it into the heat pipe body (1). ), it is best to use a valve (with gJ).

First, open the injection needle (5+ valve (g+), close the injection side valve V3, open the intake side valve (device), and start the operation of the vacuum pump (/4). Check the degree of vacuum in the internal space (A) of the main body, and when the value reaches a predetermined value, close the valve on the intake side. After this vacuum, continue to close the valve on the injection side. Open V3 to activate the supply source (l/) and send in force fluid.The amount to be injected into the internal space (A) of the main body is known from the display on the metering device (5), and that value is the amount to be sealed. The supply is continued until the pulp is reached, and then the pulp V3 is closed.
