Abstract
The invention discloses a kind of evaporator samming cold plates, belong to evaporation-cooled device technical field.Technical scheme of the present invention main points are：A kind of evaporator samming cold plate, including cold plate wall surface, it is set to the sealed frame of surrounding and the working medium import being set on sealed frame and sender property outlet on the outside of cold plate wall surface, the internal cavities of cold plate wall surface are separated into multiple interconnected gas flows by reinforcing rib, the inside of the gas flow is filled with working medium, and capillary structure is provided on the internal face of the gas flow.The present invention solves the problems, such as that existing evaporation cold plate internal working medium distribution is uneven and local temperature is excessively high, significantly improves the common evaporation non-uniform problem of cold plate temperature, and reduce flow resistance of the working medium inside cold plate.
Description
Technical field
The invention belongs to evaporation-cooled device technical fields, and in particular to a kind of evaporator samming cold plate.
Background technology
With the development of society and advancement of technology, electronic equipment integrated level is higher and higher, thing followed heating power
Density is also higher and higher, and the temperature requirement between some electronics portion elements is consistent, this heat dissipation to electronic equipment
Technology proposes test.High convection transfer rate, high latent heat of phase change and determining steaming when evaporative heat loss technology is because of its phase transformation
The advantages that sending out constant evaporating temperature when pressure as electronic equipment dissipating heat a kind of ideal product, and at present both at home and abroad competitively
The direction developed.But the terminal device cooled plate in evaporative heat loss system has that some be easy to cause cold plate at present
The problems such as non-uniform temperature is gentle stifled causes significant impact to the development of existing equipment, urgently needs a kind of new cold plate structure
To solve problem above.
Invention content
The technical problem to be solved by the present invention is to provide a kind of evaporator samming cold plates for evaporative cooling system.
The present invention adopts the following technical scheme that solve above-mentioned technical problem, a kind of evaporator samming cold plate, including cold plate
Wall surface is set to the sealed frame of surrounding and the working medium import being set on sealed frame and sender property outlet on the outside of cold plate wall surface,
It is characterized in that：The internal cavities of the cold plate wall surface are separated into multiple interconnected gas flows, the gas by reinforcing rib
The inside of runner is filled with working medium, and capillary structure is provided on the internal face of the gas flow.
Further preferably, the sealed frame is connect with cold plate wall surface vacuum brazing, working medium import and sender property outlet with
Sealed frame vacuum brazing connects.
Further preferably, the cold plate wall surface and sealed frame are copper, aluminium, titanium alloy or stainless steel.
Further preferably, the working medium is freon, acetone or alcohol.
Further preferably, the capillary structure is sintering felt, sintered meshwork, sintering powder, mechanical compaction silk screen or microflute
Road capillary structure.
The present invention has the advantages that compared with prior art：（1）Have inside cold plate corresponding with cooled equipment
Capillary structure, the capillary effect of capillary structure can quickly supplement liquid to prevent from dryouting after liquid evaporation, keep cold plate each section same
For liquid evaporation state, ensure that cold plate surface temperature is consistent；（2）There are capillary structure and big gas passage to make big portion inside cold plate
Liquid separation body is flowed by capillary structure, and gas flows the generation that phenomenon is blocked up so as to avoid equipment gas by big gas passage；
（3）The entire cooling procedure of cold plate is that evaporation process is taken away since the evaporation convection coefficient of heat transfer is very high to substantially increase cold plate
By the ability of heat dissipation product heat；（4）Since evaporation latent heat is very big, takes away bosher's mass that same heat needs and subtract significantly
It is few.

Specific implementation mode
In conjunction with attached drawing detailed description of the present invention particular content.A kind of evaporator samming cold plate, including cold plate wall surface 1, set
The sealed frame 7 for being placed in 1 outside surrounding of cold plate wall surface and the working medium import 2 being set on sealed frame 7 and sender property outlet 3, it is close
Edge banding frame 7 is linked with 1 vacuum brazing of cold plate wall surface, and working medium import 2 and sender property outlet 3 are connect with 7 vacuum brazing of sealed frame, institute
The internal cavities for stating cold plate wall surface 1 are separated into multiple interconnected gas flows 5, the inside of the gas flow 5 by reinforcing rib 6
Filled with working medium, working medium is water or ethyl alcohol, is provided with capillary structure 4 on the internal face of the gas flow 5, the capillary structure 4
For sintering felt, sintered meshwork, sintering powder, mechanical compaction silk screen or micro-channel capillary structure.
The seal and pressure bearing structure that cold plate inner cavity is made of cold plate wall surface, sealed frame and internal stiffeners in the present invention.
Heat-producing device is mounted on the cold plate wall surface for having capillary structure side inside cold plate, working medium enter after gas flow liquid working substance into
Enter capillary structure, it is rapid under the action of capillary force to be uniformly full of entire inner cavity capillary structure wall surface, when capillary structure wall surface
When the equipment heating of outside, evaporates the working medium in capillary structure inside heat transfer to capillary structure and overflow, inside cold plate
Gas passage is flowed out from sender property outlet, around supplements the liquid evaporated rapidly by the effect of capillary force with the working medium of working medium import
Body working medium space ensures that the heat that heat-producing device generates can be taken away rapidly.
This present invention evaporator samming cold plate is used as the evaporator of evaporation circulating system, and import working medium is by pumping or pressing
Contracting machine provides the fluid liquid of pressure, and carburation by evaporation takes away the heat on cold plate surface in cold plate, in the form of a vapor by cold plate
Outlet outflow cold plate, by after the components condensation liquefaction such as condenser of evaporation circulating system again by pump or compressor squeeze into cold plate into
Mouth constitutes cycle.
Have been shown and described above the basic principle of the present invention, main feature and advantage, do not depart from spirit of that invention and
Under the premise of range, the present invention also has various changes and modifications, these changes and improvements both fall within claimed invention
Range.
