Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings:
A kind of contact active Phase cooling structure of the present invention, as shown in Figure 1 and Figure 2, including is vertically arranged and top is opened
Top cover 3 is sealed and installed with the shell 1 of mouth, the top end opening of shell 1, at least one outside portion of shell 1 is vertically arranged at least
One radiating fin 2;The pressure gauge 5 and vavuum pump 6 being connected with inside shell 1, the inner side of shell 1 are installed outside shell 1
Wall, which is provided with mainboard 7, mainboard 7, is connected with euthermic chip 8, is filled with liquid working substance 12, liquid working substance 12 and passes through in shell 1
Pipeline 14 is provided with Miniature liquid pump 9, and one end of pipeline 14 is located in liquid working substance 12, the other end flashed liquid working medium of pipeline 14
12 is outer and be provided with shower nozzle 10, and shower nozzle 10 is just set to euthermic chip 8.Wherein, shell 1 is that punching press or welding procedure are integrally formed
Structure;Liquid working substance 12 is the working medium of easy phase transformation under non-conductive, corrosion-free, low vacuum;It is empty that liquid working substance 12 accounts for the inside of housing 1
Between 5%-90%, preferably 30%-50%;Top cover 3 is by sealing bolt 4 with being tightly connected at the top end opening of shell 1;Outside
The bottom of shell 1 is provided with least one fan 13;The outside portion of shell 1 is provided with power supply outer lead 11, power supply outer lead 11
One end is stretched out outside radiating fin 2.
The passive Phase cooling structure of a kind of contact of the present invention, as shown in figure 3, being opened including a horizontally disposed and side
Top cover 3 is sealed and installed with the shell 1 of mouth, the opening of shell 1, the top outer of shell 1 is provided with least one radiating fin
2, the pressure gauge 5 and vavuum pump 6 being connected with inside shell 1 are installed outside shell 1, the bottom inside wall of shell 1 is provided with
It is connected with mainboard 7, mainboard 7 in euthermic chip 8, shell 1 and is filled with liquid working substance 12, liquid working substance 12 is by mainboard 7 and generates heat
Chip 8 is completely covered.Wherein, shell 1 is punching press or the integrally formed structure of welding procedure;Liquid working substance 12 is non-conductive, nothing
The working medium of easy phase transformation under burn into low vacuum;Top cover 3 is by sealing bolt 4 with being tightly connected at the opening of shell 1;The bottom of shell 1
Portion's lateral wall is provided with power supply outer lead 11.
A kind of contact active Phase cooling structure of the present invention, the technological requirement of wherein each several part is:
1) shell 1 is integrally formed using punching press or welding procedure, and manufacture craft requires tight, it is ensured that nothing after carrying liquid
Seepage;
2) two parts about 2 points of radiating fin are inadequate in area of dissipation all using traditional " vertical " natural heat dissipation mode
When, the enhancing air flow of fan 13 (as shown in Figure 2) below outer shell;
3) sealing bolt 4 is used for the sealing of top cover 3 and shell 1;
4) pressure gauge 5 and the overall external installation of vavuum pump 6, are detached, it is ensured that vacuum state for the air in shell;Work as pressure
During power P≤setting value A, vavuum pump 6 starts;When pressure P reaches setting value B, vavuum pump 6 stops;
5) mainboard 7 is brought into close contact shell 1, and with the normal mounting of euthermic chip 8;
6) quantity of shower nozzle 10 is determined according to the emphasis heat dissipation region in shell, and the position of shower nozzle 10 is arranged on euthermic chip
8 correspondence position.
7) liquid working substance 12 is using the easy working medium of phase transformation under non-conductive, corrosion-free, low vacuum, such as fluorine class, silicone oil, ultrapure
Water etc., the liquid measure being filled with shell reaches the 1/4 of enclosure interior.
After complete machine is assembled by technological requirement, the monitoring internal pressure value of pressure gauge 5, vavuum pump 6 starts effect, keeps internal
All the time it is in vacuum state.After Miniature liquid pump 9 is powered, liquid is squeezed into pipeline 14, is sprayed onto that caloric value is big, need by shower nozzle 10
The region for wanting emphasis to radiate.Heat is taken away in heated liquid evaporation, and flows back to shell lower end along mainboard 7.Due to shell now
Upper segment space is in vacuum state, and physical factor of the liquid working substance 12 based on liquid phase-change of internal memory can evaporate a part, band
Walk the heat of top half chip area in shell.Because liquid working substance 12 has phase transition phenomena, the gas of evaporation runs into shell
During the inwall of interior low temperature, liquid can be converted into by gas and flow back to cabinet bottom, while latent heat is discharged, dissipating on cabinet outer wall
Hot fin 2 is taken away.By the circulating phase-change heat of cabinet inside, being gathered in the heat of inside can be dissipated by the fin of shell 1
Issue.When the area of dissipation of housing exterior is not enough, temperature does not reach requirement, fan 13 can be set below shell, leaned on
Fan 13 all discharges the heat of accumulation.
A kind of passive Phase cooling structure of contact of the present invention, as shown in figure 3, it " puts complete machine " upside down, will directly dissipate
Hot working fluid is filled with machine, and inner member is soaked.
After complete machine " putting upside down " is installed, liquid working substance 12 is set to be completely soaked euthermic chip 8 and mainboard 7.Equally, vavuum pump
6 and pressure gauge 5 cabinet inside is remained under vacuum conditions.Liquid working substance 12 in cabinet absorbs the heat of heater element
Amount, reaches after certain temperature, based on liquid phase-change principle, euthermic chip 8 is persistently radiated.Equally, can be in radiating fin 2
Fan is laid in outside, forces flow of external air, improves radiating effect.
In summary, the invention has the characteristics that:
1) type of cooling of phase transformation is directly contacted to euthermic chip with liquid, changes traditional computer wind-cooling heat dissipating side
Formula, substantially increases radiating efficiency;
2) chip is radiated based on liquid phase-change technology, overall structure is simple, and cost is relatively low;
3) while targetedly can carrying out liquid spray cooling to main heat sink region, the suitable spray of selection is passed through
Head, can be effectively treated to the radiating of small thermal source and irregular hot source, reduce quantities;
4) fan can be laid outside the radiating fin of shell, flow of external air is forced, accelerates the flow velocity of gas, it is ensured that
The proper heat reduction of enclosure interior heat;When heat power consumption is small, fan can be closed, by Natural Heat Convection, according to heat
The quantity of fan is opened in payload, adjustment, realizes maximum energy-conservation;
5) liquid working substance uses nonconducting liquid working substance, and safety coefficient is high.
Embodiments described above is only a part of embodiment of the invention, rather than whole embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, the scope of protection of the invention is belonged to.
