It is directly connect with flat part 10, at this point, the closed cavity is made of the first cavity 101 and the second cavity 201.
Negative pressure state is set as in the closed cavity, as a result, the boiling point of the liquid phase-change working medium under negative pressure state
It reduces, to be conducive to the heated rear rapid evaporation of phase-change working substance, transfers heat to fin part 20 in time to radiate.It can be with
Understand ground, the phase-change working substance includes but is not limited to water, alcohol and propyl alcohol.In addition, since the closed cavity is in that an entirety connects
Circulation passage only need to once fill i.e. it is therefore not necessary to fill the phase-change working substance respectively to the first cavity 101 and the second cavity 201
Can, filling efficiency is improved, filling cost is saved.In addition, phase-change working substance liquid level is lower than under non-heat dissipation working condition
The upper edge of first cavity 101.
In use, the inside (that is, side far from fin part 20) that the heat source to radiate will be needed to be mounted on flat part 10,
Or, the inside of heat from the flat part 10 of heat source is transmitted to flat part 10 close to the inside of flat part 10, liquid phase-change working medium is inhaled
It is vaporized after heat, flowing to 20 exothermic condensation of fin part is liquid phase-change working medium, is back to flat part 10.
It should be noted that when installing the plate-type heat-pipe, when meeting fin part 20 and being located at the top of flat part 10, such as
This, when liquefaction generates liquid phase-change working medium to gaseous state phase-change working substance to the cold at fin part 20, liquid phase-change working medium can be certainly
Under the action of body gravity in automatic back flow to the first cavity 101 of substrate 10.
Based on this, referring to Fig. 7, the present invention also provides a kind of processing method for processing above-mentioned plate-type heat-pipe, it should
Processing method the following steps are included:
Step S10: blanking is cut into the metal substrate of two pieces of same sizes according to technique requirement after smoothing sheet metal
1.When as remained grease stain impurity on sheet metal, in order to guarantee the performance of plate-type heat-pipe, before being cut, need to pass sequentially through pair
Sheet metal removes grease stain after carrying out the surface treatment such as alkaline degreasing, acid-base neutralization, hot water spray, drying.In present embodiment, gold
Belonging to piece is aluminium flake or aluminum alloy sheet.The lighter weight of aluminium flake, easy to process, anti-corrosion capability is strong, and at low cost, can be effectively controlled
Production cost.It is to be appreciated that sheet metal is also an option that copper sheet etc. in other unshowned embodiments.
Step S20: printing lid closes, referring to Fig. 8, figure, ruler on wherein one piece of metal substrate 1 according to process requirement
Agent is rolled in the printing resistance of little progress row, wherein the region of dash area is the region printed resistance and roll agent in Fig. 5.Resistance rolls agent after drying
It is solidificated on metal substrate 1, then closes other one piece of metal substrate 1 lid on being printed with the metal substrate 1 that agent is rolled in resistance, so that
Resistance is rolled agent and is located between two pieces of metal substrates 1.
It should be noted that it is the material for preventing double-level-metal plate from combining by rolling that agent is rolled in resistance, such as conventional
It is graphite lotion that agent is rolled in resistance.Agent coating is rolled into resistance or is printed between double-level-metal plate, the double-layer metal plate can be made to carry out
It when Rolling compund, coats or is printed with resistance and roll the region of agent and be unable to rolling bonding and be integrated, the double-layer metal plate in the region is still
The double-layer structure that is separated from each other is kept, forms pipeline in the part for coating or being printed with resistance and roll agent through inflation.
Specifically, resistance is rolled agent and is completely in the plate face of metal substrate 1, and the region that agent is rolled in resistance is printed on metal cover board 1
Including the first area Zu Zha 11 and multiple the second areas Zu Zha 12 being connected with the first area Zu Zha 11.Wherein set in the first area Zu Zha 11
