Summary of the invention
For the problems referred to above, present invention aim to address that current Worm type feed supply device radiation efficiency is low, and make an uproar
The technical problem that sound is big.
For solving above-mentioned technical problem, the technical solution used in the present invention is Worm type feed supply device, including heat radiation
Module, described radiating module includes cooling down fan, radiator and soaking plate.Described cooling fan is installed on radiator side, institute
State soaking plate and be installed on the lower section of radiator.
Described soaking plate include copper coin, lower copper coin, upper copper powder sintering layer, lower copper powder sintering layer, solid hexagonal copper post and
Copper powder ring.The thickness of described lower copper coin is less than upper copper coin so that lower copper coin can reduce thermal source to the thermal resistance of working medium, and upper copper coin rises
Supporting role.Upper copper powder sintering layer is sintered in the lower surface of copper coin, as the evaporation ends wick of soaking plate.Lower copper powder sinters
Layer is sintered in the upper surface of lower copper coin, as the condensation end wick of soaking plate.Multiple described solid hexagonal copper posts are in lower copper coin
On be spaced, connected by copper bar between adjacent two solid hexagonal copper posts, formed hex shape.Described solid hexagonal copper
Post one end is soldered to copper coin, and the other end is soldered to lower copper coin.Described copper powder ring wraps up solid hexagonal copper post, connects evaporation respectively
End wick and condensation end wick.
Described soaking plate manufacturing process is simple, low cost, the most also has extraordinary heat conductivity and excellent resisting is dried up
Performance.Use the mode of the embedding solid hexagonal copper post of copper powder ring set as support column, enhance the mechanical strength of soaking plate, simultaneously copper
Powder ring contacts with evaporation ends and condensation end wick, forms the path of working medium backflow.
Compared with relevant soaking plate, solid hexagonal copper post strengthens the mechanical strength of soaking plate.Be used alone solid hexagonal
Copper post is compared, and the machinery that the hex shape structure that multiple solid hexagonal copper posts are interconnected to form further enhances soaking plate is strong
Degree.Be possible not only to internal pressure less than external pressure time (during vacuum) provide support, prevent soaking plate under atmospheric pressure by
Flatten, simultaneously can also be between when internal pressure is more than external pressure, (when working under high temperature) keeps between upper and lower copper coin
Away from, prevent soaking plate from expanding deformation.
In traditional soaking plate structure, working medium needs the side by soaking plate to return to evaporation ends from condensation end, because of
The path of this working medium backflow is longer, causes soaking plate efficiency low, and evaporating area dry-out easily occurs.And this soaking plate uses
Copper powder ring is directly connected to evaporation ends and condensation end wick, as the path of working medium backflow, helps working medium to return to from condensation end
Evaporation ends.
The manufacturing process of this soaking plate is as follows: the upper and lower copper coin of (1) stamping-out molding, and is carried out；Copper powder is positioned over
Lower copper coin inner surface, vacates the position placing solid hexagonal copper post, and fixes with graphite jig, then carry out the sintering of copper powder；
(2) carrying out ultrasonic activation after copper powder being positioned in ring-shaped graphite mould compacting, frequency of vibration is 10kHz, sinters out copper powder
Ring；(3) solid hexagonal copper post is positioned over, with copper powder ring, the position that lower copper coin is vacated, by good for arrangement solid hexagonal copper post and copper powder
Ring fixing during copper coin is positioned over graphite jig up and down, is then placed in high pressure combustion freezing of a furnace, with nitrogen as protection atmosphere, enters
Row pressure diffusion welds, and uses the mode that stage heats up in sintering process, and the first stage is raised to the programming rate of 20 DEG C/min
300 DEG C, it is incubated 10min, is then rapidly increased to 800 DEG C of inside holding 2 hours with the programming rate of 25 DEG C/min, is finally cooled to room
Temperature；(4) get out in the bleeding point position welded and can put into the circular hole of copper pipe of bleeding；Copper pipe is placed at bleeding point, and auxiliary
With the help of helping solder, by high-frequency welding, copper pipe is welded together with soaking plate；(5) mode that negative pressure is filled is used,
After low temperature evacuation, by copper pipe, working medium is filled the working medium selected herein to soaking plate is deionized water；(6) after fill, will
Copper pipe mouth flattens and welds, it is ensured that soaking plate air-tightness；(7) finally soaking plate carried out hot pressing and cold pressing, it is ensured that soaking plate
Surface smoothness.Due to deionized water, to have latent heat high, and surface tension is big and the advantage such as avirulence, in the present embodiment, and choosing
Selecting deionized water is working medium.
In described soaking plate, the transmission of heat mainly has two approach: one is that working medium absorbs heat in evaporation ends wick
Evaporation, and in the release heat condensation of condensation end wick, by heat from evaporation ends band to condensation end, this is also that soaking plate phase transformation passes
The approach that thermal technology makees；Another is the existence due to support column, and heat can be by connecting the solid copper pin of upper and lower copper coin from lower past
Upper transmission.
