Abstract
A kind of open-type heat pipe has a hollow shell, and its one or both ends are provided with end cap, and the inner surface additional hairiness is inhaled material, and hollow shell is provided with feeding device and steam outlet pipe, and feeding device is if adopt feed tube then to insert in the hollow shell.The outer surface of hollow shell is provided with concavo-convex or cellular decorative pattern.
Description
The present invention relates to a kind of heat transfer element, relate in particular to the heat transfer element-open-type heat pipe in fields such as a kind of generation that can be used for general heat exchange, steam, metallurgy, chemical industry, automobile, refrigeration, machinery, cooker UTILIZATION OF VESIDUAL HEAT IN, energy-conservation, water saving and chemical industry.
Heat pipe is a kind of new and effective heat transfer element, Gu it is at gas-gas, gas-solid, solid-as to have positive effect in conducting heat, heat flux is big, but effect obviously descends in solution-air, liquid-liquid, liquid-solid heat transfer, and existing heat pipe is sealing device, and working medium is housed, and its change of pressure scope is big, be about vacuum~tens atmospheric pressure, tube wall is thicker, and effectively heat transfer area is little, and adiabatic section and condensation segment have taken many useful areas, entire thermal resistance is big, the processing technology complexity, manufacturing technology requires high, and service life is short, consumable material is many, and applicable surface is narrow.
The objective of the invention is to avoid above-mentioned weak point of the prior art, Gu and provide a kind of in solution-air, liquid-liquid, liquid-solid, solid-heat conduction low, the effective heat transfer area of thermal resistance big, rate of heat transfer is fast, consumable material is few, long service life, widely applicable, and processing technology is simple, manufacturing technology requires low open type heat pipe.
Purpose of the present invention can reach by following measure:
The accompanying drawing drawing is described as follows:
Fig. 1~5 are the structural representation of five embodiment of the present invention.
Referring to Fig. 1, the present invention has a hollow shell 3, and its inner surface additional hairiness is inhaled material 4, and hair suction material 4 can adopt wire, net, scrim, ceramic material or directly carve at the inner surface of hollow shell 3 and pull into thin groove.The outer surface of hollow shell 3 can be rolled into various ridge designs or become cellular through sintering, chemical treatment, to increase area of heat transfer.Feeding device 2 is if adopt feed tube, and then one or more feed tubes insert in the hollow shell 3, and the mouth of pipe that feed tube inserts hollow shell 3 both can be a scarf, also can cut a plurality of notches, breach, can also be flat mouthful.The cross section that the hair of also available hollow shell 3 one ports of feeding device 2 is inhaled material 4 replaces, and sees Fig. 3.One or more steam outlet pipes 5 are located on the hollow shell 3, and steam outlet pipe 5 also can directly use a port of hollow shell 3 to replace, and inserts feed tube in the another port, sees Fig. 2.The number of steam outlet pipe 5 must be greater than the number of feed tube, or the cross-sectional area sum of steam outlet pipe 5 must be greater than the feed tube cross-sectional area.Steam outlet pipe 5 also can be made into taper, to enlarge cross-sectional area, reduces gas flow rate and noise reduction, sees Fig. 4.On steam outlet pipe 5 and feed tube filter can be set, be heated the impurity or the particulate of liquid with filtering, filter can adopt dismountable porous filter material 7 or dismountable porous plate 6.The both ends or one end of hollow shell 3 are provided with the end cap 1 with hollow shell 3 sealings.During application, with feeding device 2 of the present invention and steam outlet pipe 5 be heated fluid pipeline, container or equipment and be tightly connected.Being heated liquid is entered in the hollow shell 3 of open-type heat pipe by feeding device 2, inhale material 4 by hair and will be heated all inner surfaces that the liquid conveying is covered with hollow shell 3, the heat of thermal source reaches its inner surface rapidly by the outer surface of hollow shell 3, the liquid that is heated that makes hair inhale material 4 absorption is vaporized rapidly, and produce certain pressure, gas enters pipeline, container or equipment by steam outlet pipe 5 under the effect of pressure, stir being heated liquid and carrying out the direct heat exchange with it in it, gas itself is condensed into and is heated liquid.Be heated liquid constantly enter in the open-type heat pipe hollow shell 3 again carry, be covered with, cyclic process such as heat absorption, vaporization, discharge, stirring, condensation, then be heated liquid rapidly, be heated equably, vaporize.Because the feed tube of open-type heat pipe inserts in the hollow shell 3, so can play the fluid-tight effect, promptly can only enter liquid, can not discharge gas, this circulation is unidirectional circulation, and circulation rate constantly increases, and can transmit a large amount of heats thus quickly, if to steam is purpose, then the feed tube of open-type heat pipe is connected with the pipeline of carrying liquid or the container of carrying liquid; Steam outlet pipe 5 and jet chimney, superheater, drum or use the equipment container etc. of steam to be connected, its condensed water returns liquid-transport pipe-line or splendid attire is heated the equipment or the container of liquid, thereby constitutes a big circulatory system.
The utility model compared with prior art has following advantage:
1, open-type heat pipe has only vaporescence, and does not have thermal insulation and condensation process, so effective heat transfer area is big, thermal resistance is little.
2, operating pressure is with to be heated fluid pressure identical, and pressure changes very little, no vacuum requirement, and pipe thickness is little, thus the saving material, and long service life.
3, the rate of heat transfer height is difficult for scaling.
4, manufacturing process is simple, and process technology requires low.
5, in fields such as the generation of general heat exchange, steam, metallurgy, automobile, cooker, machinery, UTILIZATION OF VESIDUAL HEAT IN, energy-conservation, water saving, chemical industry, has extensive use.
