Description
Technical field
The utility model relates to the heat abstractor in electronic equipment, electronic devices and components and the industrial circle, refers in particular to the evaporation that utilizes working medium--and the condensation phase transformation realizes a kind of heat abstractor of realizing that high heat flux conducts heat of heat transferred.
Background technology
Fast development along with electronic technology, the densification of the high frequency of electronic device, high speed and integrated circuit and miniaturization, make the caloric value of unit volume electronic device increase fast, the high hot-fluid that device inside produces has caused very big threat to the reliability of device itself.Because the high heat flux radiating requirements of electronic devices and components, make the heat convection method of traditional dependence monophasic fluid and the radiating mode of air blast cooling be difficult to satisfy modern many dissipation from electronic devices requirements in some cases, therefore utilize the heat pipe of phase-change heat special advantages to be arranged in the high heat flux heat radiation.The structure principle chart of traditional heat pipe as shown in Figure 1, wherein 1 is shell, 2 is capillary wick, 3 is steam channel.This heat pipe is some certain advantage aspect the transmission of high hot-fluid, but also comes with some shortcomings.Little as this heat-pipe apparatus in the disengagement area of evaporation section, and the local steam that produces of some of evaporation section will be by the liquid working substance of porous core and porous in-core, the flow resistance that this has increased fluid has naturally greatly reduced the Heat Transfer of Heat Pipe on Heat Pipe ability, makes simultaneously to carry the easier formation of limit; Because the porous core is between tube wall and gas passage, increased difficulty then in the production process installation of porous core, the installation that particularly has the sintering capillary wick of superior performance brings difficulty (could use the requirement of sintering capillary wick is very harsh), the cross-sectional area of capillary wick is very little simultaneously, the flow velocity of liquid is higher under the situation of same liquid flow, and the liquid of high flow velocities can produce bigger flow resistance when flowing in the porous core, thereby makes its capillary limit lower, and heat-transfer capability is not high.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provides a kind of and makes it can improve heat-transfer capability, adapts to the demand of high heat flux heat radiation, makes its heat abstractor easy to process, that production efficiency is high simultaneously.
The technical solution of the utility model is a kind of heat abstractor that comprises following design feature of structure:
Heat abstractor is made up of tube-like envelope, is divided into evaporation section, interlude, condensation segment, utilizes the evaporation of inner loop refrigeration working medium, the transmission that the condensation phase transformation realizes heat;
Described shell and heating fin are formed the cavity volume of a tubulose, insert circularly cooling working medium in the cavity volume, are used for Working fluid phase changing and freeze;
The centre of described tubulose cavity volume is provided with capillary porous core, is used for the liquid refrigeration working medium of condensation segment is pumped to the evaporation section evaporative heat loss.
Advantage of the present utility model and beneficial effect:
1, the utility model is because the porous core is positioned at pipe central authorities, and cross-sectional area is bigger, and liquid flow velocity is little in it, it is little that thereby flow of liquid is crossed the flow resistance (this is the main crushing of heat pipe) of capillary wick, cause the capillary limit of system big, heat-transfer capability is big, the heat transfer efficiency height; Owing to install easily, can adopt high performance sintering capillary wick simultaneously, further improve the capillary limit and the heat-transfer capability of system.
2, the utility model is owing to the heating fin directly contacts with capillary wick, the evaporating surface of its evaporation section is increased, make its uniform temperature better, the steam that evaporation simultaneously produces directly enters steam channel and gets back to condensation end, do not pass through porous core and liquid, thereby crushing is little, and the capillary limit for height of system further improves heat-transfer capability.
3, the utility model is simple in structure, and is easy to process, good in economic efficiency.
