Description

The high heat-flux heat exchanger
Technical field
The utility model relates to a kind of employed solution-air of chemical industry, oil, metallurgy and Thermal Power Engineering, liquid-gas, gas-gas or liquid-liquid heat exchanger that is used for.
Background technology
Existing solution-air, liquid-gas, gas-gas or liquid-liquid heat exchanger is made of housing and two ends end socket thereof and the heat exchanger tube that is arranged on enclosure interior, because its heat exchanger tube adopts light pipe, screwed pipe or low finned tube to make, then the heat transfer efficiency of this heat exchanger is low, what particularly its liquid flowing resistance increased is too big, so that has influenced its use.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of heat transfer efficiency height, high heat-flux heat exchanger that fluid flow resistance is little are provided.
Technical solution of the present utility model:
A kind of high heat-flux heat exchanger, it includes the capping at housing and two ends thereof, be provided with heat exchanger tube by forward and backward tube sheet in the housing, in capping, be provided with medium import and media outlet, on housing, be provided with material inlet and material outlet, wherein, heat exchanger tube or many straight tubes that are arranged side by side, or the many U type pipes that are arranged side by side, it is characterized in that the inwall of each heat exchanger tube or outer wall are provided with porous metallic layers.
The utility model is in the spraying of inside and outside surface or the sintered porous metal coating of each heat exchanger tube, so the utility model compared with prior art, because heat exchanger tube has adopted efficient coating heat exchanger tube, then the coefficient of heat transfer improves greatly.And support heat-exchanging tube bundle of the present utility model adopts the baffling structure, and rod baffle contacts with heat exchanger tube, and the housing inner fluid is with axial flow, and fluid flow resistance is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of heat exchanger tube of the present utility model.
The specific embodiment
As Fig. 1,2, high heat-flux heat exchanger of the present utility model, it includes the capping 2 at housing 1 and two ends thereof, is provided with heat exchanger tube 4 by forward and backward tube sheet 3 in the housing 1, is provided with medium import 5 and media outlet 6 in capping 2, on housing 1, be provided with material inlet 7 and material outlet 8, wherein, heat exchanger tube 4 can be many straight tubes that are arranged side by side, also many U type pipes that are arranged side by side, characteristics of the present utility model are that the inwall of each heat exchanger tube 4 or outer wall are provided with porous metallic layers 9.
Porous metallic layers 9 of the present utility model can adopt 60-120 purpose aluminium powder, iron powder or nickel powder sintering or be painted on the inwall or outer wall of each heat exchanger tube 4 in vacuum high temperature furnace, form rough a large amount of aperture, can quicken vaporizing liquid greatly and generate bubble.The thickness of this porous metallic layers 9 is 0.2-0.8mm, best 0.5-0.7mm.
Preferred plan of the present utility model is, is provided with porous metallic layers 9 simultaneously at the inner and outer wall of each heat exchanger tube 4.
In the utility model, can come support fixation by the many rod baffle 10 that are welded on the baffling circle in the middle of each heat exchanger tube 4, rod baffle 10 be thin round bar, is weldingly fixed on the baffling circle of annular with level or vertical direction respectively to constitute support.Because of each corrugated tube 4 adopts the rod baffle supporting constructions, it has determined housing 1 inner fluid to flow with axial flow direction, thereby has reduced flow resistance, also makes heat exchanger tube less scaling, and has eliminated because of the fluid vibration problem that produces of disturbance significantly.
The utility model should be provided with the floating head structure that is made of Floating Head Flange 11 and hook circle 12 in the rear end of housing 1 capping 2 when temperature of charge is higher, each heat exchanger tube 4 and back tube sheet 3 are moved in housing 1.
The utility model is in the inside and outside surperficial pyrolytic coating of efficient heat-exchanging pipe or sinter porous metal coating into, because the heat exchanger tube surfaces externally and internally has formed rough a large amount of aperture, makes surface area increase tens of times, has quickened vaporizing liquid greatly and has generated bubble.The high heat-flux heat exchanger is exactly this enhanced heat transfer mechanism that has made full use of efficient liquid film evaporation.In addition, heated medium enters in the liquid medium very soon at the bubble that heat exchanger tube surface endothermic gasification generates, because the temperature of liquid medium is lower than bubble slightly, bubble is very fast to be become liquid by the fluid condensation.Therefore, the heat that bubble is absorbed in generating has been passed to liquid medium with the form of condensation heat again, and because of the heat of this latent heat is very big, and transmission speed is fast again, thereby has improved heat transfer rate greatly.Its total effect is to have improved heat transfer coefficient greatly, and can be under less heat transfer temperature difference the enhanced boiling heat transfer process, along with the temperature difference increases, heat flux sharply rises.The heat transfer and light pipe need just can come to life under sizable temperature difference.Shell side of the present utility model is suitable for clean medium, as demineralized water, liquid hydrocarbon etc., can be widely used in industries such as petrochemical industry and electric power.
