Abstract

This invention discloses a method for accelerating ageing to vacuum sealed products including the following steps: 1, putting a vacuum sealed product to be tested in a furnace, 2, penetrating gas N and H to the furnace anf heating it till the temperature and pressure reach to the pre-designed values, 3, timing and controlling the acceleration of the product in the furnace in terms of the designed time, 4, releasing the pressure after the timing and taking out the product, which accelerates the ageing of products by heating and adding pressure at the same time.

Description

【Technical field】

[0001] The present invention relates to a method for accelerated aging of vacuum-sealed products. 【Background technique】

[0002] Vacuum sealing products are widely used in real life. Taking the heat dissipation field as an example, in order to solve the heat dissipation problem of high heat density, the industry has invented various heat dissipation solutions that use the principle of phase change for heat transfer. In various fields of heat dissipation, such as the field of electronic heat dissipation and the field of aviation, the typical product is a heat pipe (Heat Pipe), which is made by setting a gas-tight cavity in the pipe body, vacuuming the cavity, and injecting an appropriate amount of heat of vaporization. Working fluid with good fluidity, stable chemical properties and low boiling point, such as ammonia water, methanol, ethanol, water or acetone, etc., is sealed, and the inner wall of the shell is usually provided with a capillary structure (C...
