Abstract
An ageing method for heat transfer tube includes such steps as putting a heat transfer tube in a container, filling non-reactive gas, sealing the container, heating to a predefined temp, holding the temp for a certain time, and cooling. Its advantages are high speed and no pollution.
Description
Technical field
The present invention is relevant with heat pipe, is meant a kind of aging process of heat pipe especially, the rapid and compliance with environmental protection requirements of its processing procedure.
Background technology
The fabrication schedule of existing heat pipe mainly is the end sealing of elder generation with a copper pipe, inject behind the copper powder in addition high temperature sintering, a spot of water that reinjects, then under vacuum environment with the other end involution of copper pipe, and with heat pipe bending or flatten into reservation shape, promptly finish the machining of heat pipe.Owing to can produce residual stress at copper pipe itself during machining unavoidablely, therefore,, can do timeliness (aging) processing usually, with the elimination residual stress for increasing product service life.
The aging process of traditional hot conduit is that heat pipe be impregnated in glycerine or other the suitable high boiling liquids, and the temperature that keeps this liquid is in about 120 ℃, dip time was kept about 24 hours, purpose makes this heat pipe can rearrange its crystal lattice under the state of high temperature anaerobic, to eliminate residual stress, and avoid oxidation reaction, yet, after heat pipe takes out, must utilize chemical solvent to remove the glycerine that adheres to, not only consuming time bothersome, and the processing of chemical solvent and glycerine waste liquid also often causes problem of environmental pollution.
Summary of the invention
Main purpose of the present invention is to provide a kind of aging process of heat pipe, and its processing procedure is rapid merely.
A time purpose of the present invention is to provide a kind of aging process of heat pipe, and it can avoid the generation of polluting.
Take off purpose for before reaching, the aging process of heat pipe provided by the present invention is to include following steps: at first a heat pipe is inserted in the container, again a non-reactive gas is injected this container and seal this container, then, heat this container, this non-reactive gas and this heat pipe to one predetermined temperature, and continue for some time, last, with the cooling of this container, and with this heat pipe by taking out in this container.
In order to describe structure of the present invention and characteristics place in detail, lift now with next preferred embodiment and cooperate graphic explanation as after.
Description of drawings
Fig. 1 is the schematic diagram of a preferred embodiment of the present invention.
The specific embodiment
See also Fig. 1, the timeliness of the heat pipe that a preferred embodiment of the present invention provided (aging) method, be earlier a heat pipe 10 of finishing machining to be inserted in the container 12, this container 12 has a body 14 and a lid 16, these body 14 inside are hollow and have a room 18,16 of this lids are in order to seal this room 18, this container 12 also has an air inlet 20 and a bleeding point 22, after inserting the heat pipe 10 of right quantity (as three) in this room 18, utilize this lid 16 these rooms 18 of sealing, one non-reactive gas can be injected this container 12 by air inlet 20, the oxygen of its purpose in getting rid of room 18, to avoid causing in the follow-up heating process oxidation of heat pipe 10, the practical operation program is to be bled by bleeding point 22 earlier to make this room 18 form vacuum state, then pour into non-reactive gas by air inlet 20, close this bleeding point 22 after a period of time, this moment, non-reactive gas still continued to inject this room 18, when arriving a predetermined pressure, seal this air inlet 20 again as an atmospheric pressure.Wherein, this non-anti-property gas can adopt and be not limited to the wherein mixture of one or two or more kinds of inert gas (as helium (He), neon (Ne), hydrogen (Ar) etc.) and nitrogen, in fact, only otherwise the gas that can react with the material (as copper) of heat pipe all can adopt.
Then, this container 12 is placed a baking box 24, utilize this this container 12 of baking box 24 heating and wherein non-reactive gas and this heat pipe 10, the temperature of heating is 100 ℃～140 ℃, with 120 ℃ be the best, the heating and continuous time is 18 hours～30 hours, is the best with 24 hours; At last, open this baking box 24 and make this container 12 reduce to room temperature, again with this heat pipe 10 by taking out in this container 12, promptly finish whole timeliness step.
Utilize the aging process of heat pipe provided by the present invention, need not to use chemicals such as glycerine, also need not to carry out cleaning afterwards, heat pipe can be packed shipment after taking out in the container, not only processing procedure is simple and easy fast, also can not produce the harmful substance of contaminated environment, though the method is in other field or employing is arranged, so in the relevant technical field of heat pipe, the present invention proposes first really and has an enhancement effect.
