Abstract

PURPOSE:To prevent the gas leakage permanently perfectly, by sealing Freon gas and the like in the temperature sensitive tube for a cooling device and the like, compressing the vicinity of a tip part, inserting silver solder and the like between the compressed part and the tip part, temporarily sealing the tip part, and melting the silver solder and the like by heating. CONSTITUTION:The tip part 14 of the temperature sensitive tube and the like 10 made of copper is compressed, and a first temporary sealing part 11 is formed. A sealing agent 13 such as the silver solder is inserted in a space 12 at the outside of the part 11. Thereafter, a tip part 14 is compressed and a second temporary sealing part 15 is formed. Then heat is applied from the outside so as to melt the sealing agent 13 and the sealing is performed perfectly. By this double sealing, the inside of the second sealing part of the tube 10 is perfectly coated by the sealing agent. The leakage due to the presence of oxide, dust, and the like can be perfectly eliminated in comparison with the case where only compression is performed.

Dan: Conventionally, as shown in Figure 1, the gas sealing method for this temperature-sensing tube is to perform an If image 2 of the area near the tip J of the temperature-sensing tube 1 using a tick (not shown), and then heat it externally. If the copper or other metal constituting the thermosensing tube is oxidized or is resistant to dust, please take the time to press the area around the tip. However, due to the oxide film or dust, the metals could not be joined together, so even if soldering was applied from the outside for reinforcement, gas leakage still occurred.
