Abstract
The invention discloses an evaporator temperature equalizing and cooling plate belonging to the technical field of the evaporation cooling device. The invention is characterized in that an evaporator temperature equalizing and cooling plate comprises a cooling plate wall face, a seal frame arranged at outside periphery of the cooling plate wall face, and a working medium inlet and a working medium outlet arranged on the seal frame; the inner cavity of the cooling plate wall face is separated into multiple mutually communicated gas flow channels through reinforcing ribs; the gas flow channels are filled with working media; and capillary structures are arranged on the inner wall faces of the gas flow channels. According to the evaporator temperature equalizing and cooling plate of the invention, the problem that the working media in the existing evaporation cooling plate are distributed unevenly and the partial temperature is overhigh is solved; the problem that the temperature of the ordinary evaporation cooling plate is uneven is remarkably improved; and the flow resistance of the working media in the cooling plate is reduced.
Description
Technical field
The invention belongs to evaporation-cooled device technical field, be specifically related to a kind of evaporator samming cold drawing.
Background technology
Along with the development of society and the progress of technology, electronic equipment integrated level is more and more higher, thing followed thermal power density is also more and more higher, and temperature requirement between some electronics portion element is consistent, and this proposes test to the heat dissipation technology of electronic equipment.The advantages such as the evaporating temperature that evaporative heat loss technology is constant because of convection transfer rate high during its phase transformation, high latent heat of phase change and when determining evaporating pressure become a kind of ideal product of electronic equipment dissipating heat, are also directions of competitively developing both at home and abroad at present.But the terminal equipment cooled plate at present in evaporative heat loss system exists some problems easily causes the uneven gentle problem such as stifled of cold plate temperature, causes significant impact to the development of existing equipment, urgently need a kind of new cold drawing structure to overcome the above problems.
Summary of the invention
The technical problem that the present invention solves there is provided a kind of evaporator samming cold drawing for evaporative cooling system.
The present invention adopts following technical scheme for solving the problems of the technologies described above, a kind of evaporator samming cold drawing, comprise cold drawing wall, be arranged at the sealed frame of surrounding outside cold drawing wall and the working medium import that is arranged on sealed frame and sender property outlet, it is characterized in that: the internal cavities of described cold drawing wall is separated into multiple gas flow be interconnected by reinforcement, the inside of this gas flow is filled with working medium, and the internal face of described gas flow is provided with capillary structure.
Further preferably, described sealed frame is connected with the vacuum brazing of cold drawing wall, and working medium import is connected with sealed frame vacuum brazing with sender property outlet.
Further preferably, described cold drawing wall and sealed frame are copper, aluminium, titanium alloy or stainless steel.
Further preferably, described working medium is freon, acetone or alcohol.
Further preferably, described capillary structure is sintering felt, sintered meshwork, sintered powder, mechanical compaction silk screen or micro-channel capillary structure.
The present invention compared with prior art has following beneficial effect: there is the capillary structure corresponding with cooled equipment (1) cold drawing inside, after liquid evaporation, the quick liquid make-up of capillary effect energy of capillary structure is to prevent from dryouting, make cold drawing each several part be all liquid evaporating state, ensure that cold drawing surface temperature is consistent; (2) cold drawing inside has capillary structure and large gas passage that most of liquid is flowed by capillary structure, and gas is by the flowing of large gas passage thus the equipment gas of avoiding blocks up the generation of phenomenon; (3) the whole cooling procedure of cold drawing is evaporation process, because evaporation convection heat exchange coefficient is very high, thus substantially increases cold drawing and takes away by the ability of heat radiation product heat; (4) because evaporation latent heat is very large, the bosher's quality taking away same caloric requirement greatly reduces.

Embodiment
Describe particular content of the present invention by reference to the accompanying drawings in detail.A kind of evaporator samming cold drawing, comprise cold drawing wall 1, be arranged at the sealed frame 7 of surrounding outside cold drawing wall 1 and the working medium import 2 be arranged on sealed frame 7 and sender property outlet 3, sealed frame 7 links with cold drawing wall 1 vacuum brazing, working medium import 2 is connected with sealed frame 7 vacuum brazing with sender property outlet 3, the internal cavities of described cold drawing wall 1 is separated into multiple gas flow 5 be interconnected by reinforcement 6, the inside of this gas flow 5 is filled with working medium, working medium is water or ethanol, the internal face of described gas flow 5 is provided with capillary structure 4, this capillary structure 4 is sintering felt, sintered meshwork, sintered powder, mechanical compaction silk screen or micro-channel capillary structure.
The seal and pressure bearing structure that in the present invention, cold drawing inner chamber is made up of cold drawing wall, sealed frame and internal stiffeners.Heat-producing device is mounted on cold drawing inside to be had on the cold drawing wall of capillary structure side, after working medium enters gas flow, liquid working substance enters capillary structure, whole inner chamber capillary structure wall is full of uniformly rapidly under the effect of capillary force, outside capillary structure wall during equipment heating, heat is delivered to capillary structure inside makes the working medium evaporation in capillary structure overflow, flowed out from sender property outlet by cold drawing internal gas passageways, the working medium of surrounding and working medium import supplements rapidly by the effect of capillary force the liquid working substance space evaporated, ensure that the heat that heat-producing device produces can be taken away rapidly.
This present invention evaporator samming cold drawing uses as the evaporator of evaporation circulating system, import working medium is the fluid liquid being provided pressure by pump or compressor, in cold drawing, carburation by evaporation takes away the heat on cold drawing surface, being exported by cold drawing in the form of a vapor and flow out cold drawing, forming circulation by squeezing into cold drawing import by pump or compressor again after the parts condensation liquefactions such as the condenser of evaporation circulating system.
More than show and describe general principle of the present invention, principal character and advantage, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present invention.
