The inner wall of the metal pipe is provided with a groove and the metal pipe is filled with the phase change medium. The utility model has the advantages of strong heat conduction and heat dissipation power up to 50-200W/CM<2>, low cost, simple structure and convenient use.
Description
Technical field
The utility model relates to radiator, relates in particular to the phase-change heat pipe that microcomputer central processing unit (CPU), video card and communication apparatus are used.
Background technology
At present, the radiating treatment of the components and parts of microcomputer CPU, video card and communication apparatus central processing unit is to dispel the heat by adding to put than big copper block or other thermal conductive metallic material heat conduction, or dispels the heat with fan, perhaps directly uses water condensation.This radiating mode has following shortcoming: the fan heating surface is low, can not quick heat radiating; And add the heat conduction power put than big copper block or other thermal conductive metallic material only at 30W/CM
2Below, its radiating effect is poor, the heat radiation in the time of can not satisfying equipment operation, and especially along with the upgrading of microcomputer, communication apparatus, the increasing of equipment operation power, the problem of its heat radiation is outstanding all the more.
Summary of the invention
The purpose of this utility model provides radiator, especially provides a kind of microcomputer central processing unit (CPU), video card and communication apparatus employed phase-change heat pipe, has overcome the shortcoming of above-mentioned radiator.
The purpose of this utility model is achieved through the following technical solutions:
A kind of phase-change heat pipe is an enclosed metal body, and it is characterized in that: described metal body is a hollow tubular, and described metal body one end is made as the heating end of sealing, and its other end neck is the injection end of phase change medium; The inwall of described metal body is provided with groove; Be full of in the described metal body phase change medium is arranged;
Described groove can be the groove of vertical linear pattern, spiral type, reticular pattern, purpose is to be beneficial to described liquid chemical medium can circulate along groove in described metal body, order about the change of phase change medium layer form, thereby drive the heat acceleration cycle cooling of described metal tube body; Described groove also can be accelerated described chemical mediator circulation flow rate, thereby accelerates the heat conduction and heat radiation power of heat production components and parts;
Described chemical mediator can be the potassium sulfate material;
The heating end of described metal body has a socket.
Described chemical mediator can be one pack system or composition, as liquid sulfuric acid potassium;
The heating end of described metal body can be installed on the surface of heat dissipation metal parts of microcomputer CPU, video card or communication apparatus heat production components and parts, the heat and the described metal body that are beneficial to described heat production components and parts produce heat exchange, thereby are beneficial to temperature and the heat that reduces the heat production components and parts;
The other end neck of described metal body is the injection end of phase change medium, can carry out air-cooled or water-cooled, is beneficial to cool off the heat that described metal tube body heat exchange reaches;
The diameter of described metal body and length can be the specifications of different sizes as required, and the specification of the metal body of using as microcomputer CPU can be φ 2cm * 20cm; The specification of the metal body that relatively large communication apparatus is used can be φ 15cm * 100cm.
The utility model phase-change heat pipe has the following advantages:
1, heat conduction and heat radiation power is strong, in the middle of the metal body of radiator, records heat radiation power and can reach 50-200W/CM
2, far above the heat conduction power of thermal conductive metallic material only at 30W/CM
2, increased substantially the heat conduction and heat radiation power of heat production components and parts.
2,, thereby reduced cost significantly owing to increase substantially heat conduction and heat radiation power.
3, simple in structure, easy to use.
