Description
Technical field
The utility model relates to heat transfer element, relates in particular to a kind of hot tube bundle.
Background technology
Hot pipe technique is the heat transfer element of a kind of being called " heat pipe " of George Ge Luofo (George Grover) invention of U.S. Los Alamos (Los Alamos) National Laboratory in 1963.
Liquid carburation by evaporation when an end of heat pipe is heated in the capillary wick, steam flows to another section and emits heat and condense into liquid under small pressure reduction, liquid flows back to evaporation ends along porous material by the effect of capillary force again, so circulates endlessly, and heat reaches the other end by an end of heat pipe.It has taken full advantage of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, is delivered to rapidly outside the thermal source through the heat of heat pipe with thermal objects, and its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.
Along with microelectronic chip heat flow density sharply increases and the appearance of new feature such as the efficiently radiates heat space is narrow and small day by day and new phenomenon, traditional utilization increases the method that the efficiently radiates heat area dispels the heat can not satisfy radiating requirements, and has high thermal conductivity, the good ideal element that isothermal, thermal response are fast, simple in structure, small-sized/micro heat pipe that need not advantages such as additional power driving becomes the heat conduction of high heat flux chip.Yet, because heat pipe outer surface is the face of cylinder, when being used for the heat radiation of electronic devices and components, opposite heat tube to carry out could being combined with radiator after the secondary operations, as technologies such as flattening, bendings.Yet the secondary operations of heat pipe can be damaged the micro-structural of its inwall, will greatly influence the Heat Transfer of Heat Pipe on Heat Pipe performance.
The phase-change heat transfer technology of employing plume is also arranged as the heat dissipating method of electronic devices and components at present, directly electronic devices and components are installed on the plane of plume end, but the plume internal cavities is big, degasification difficulty when vacuumizing, cause the plume internal vacuum lower than heat pipe, therefore its startability, isothermal performance can not satisfy the radiating requirements of electronic devices and components well than not as heat pipe.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming and defect of prior art, and the hot tube bundle that a kind of heat-transfer rate is fast, heat-transfer capability is strong is provided.
The utility model is achieved through the following technical solutions:
A kind of hot tube bundle comprises the tubing string body, is provided with the duct of a plurality of spaces in the tubing string body, and the inwall in the duct is provided with the imbibition sandwich layer, and the inwall in imbibition sandwich layer and duct fits tightly, and distributes in the form of a ring between the described duct; The two ends of described tubing string body are provided with upper end cover and the bottom end cover that is sealed and matched with it, and upper end cover is provided with the pumping mouth that communicates with the duct, and the end of exposing of pumping mouth seals; Be filled with liquid working substance in the described duct, vacuum seal in the described tubing string body.Described imbibition sandwich layer is metal powder sintered formula imbibition core.
When the quantity of pumping mouth was one, this pumping mouth was communicated with each duct simultaneously; When the quantity in the quantity of pumping mouth and duct was identical, each root pumping mouth independently was communicated with corresponding duct respectively.
Described tubing string body adopts copper or aluminium to make.
The utility model has the following advantages compared with prior art:
(1) is provided with a plurality of ducts in the tubing string body, the duct inwall is provided with the imbibition sandwich layer, can accelerating liquid flowing velocity and the liquid back-flow velocity of steam during the working medium gasification, improve the heat-transfer rate of hot tube bundle, strengthen its boiling and condensation heat transfer effect, strengthen its capacity of heat transmission.
(2) in this hot tube bundle, each duct is integrated in (in the tubing string body) in the hot tube bundle with parallel way, can change the duty of phase-change heat transfer according to the variation of thermal source automatically, and its capacity of heat transmission is multiplied.Whole this external surface of tubing string is radiating surface, and can add module such as heronsbill radiator, has increased area of dissipation, improves heat transfer efficiency; Hot tube bundle relies on the interior liquid working substance gasification of tubing string body condensation to carry out phase-change heat transfer, and heat-transfer capability is big.
