Plate heat exchangers iripo mune akawanda maindasitiri maapplication uye inonyanya kushandisa marata esimbi kutamisa kupisa pakati pemvura mbiri.
Kushandisa kwavo kuri kukura nekukurumidza nekuti vanokunda zvechinyakare zvinopisa kupisa (kazhinji chubhu yakamonerwa ine imwe mvura inopfuura nemukamuri ine imwe mvura) nekuti mvura iri kutonhodzwa iGreater surface area kusangana, iyo inonatsiridza kutamisa kupisa uye inowedzera zvakanyanya mwero wekushanduka kwetembiricha.
Panzvimbo pemakoiri anopfuura nemakamuri, mundiro yekupisa kupisa, kune makamuri maviri anochinjana, kazhinji ane kudzika kwakadzika, akaparadzaniswa nemarata esimbi ane marara panzvimbo dzawo huru.Imba yacho yakatetepa, sezvo izvi zvinovimbisa kuti yakawanda yehuwandu hwemvura inosangana nendiro, ichibatsira kuchinjana kwekupisa.
Mahwendefa akadaro ekutsinhanisa kupisa agara akagadzirwa achishandisa chidhindo kana kugadzirwa kwakajairika sekudhirowa kwakadzika, asi munguva pfupi yapfuura photochemical etching (PCE) yakaratidza kuti ndiyo yakanyatsoshanda uye isingadhuri nzira yekugadzira inowanika kune iyi yakaoma application. dhizaini uye kugadzirwa kwezvishandiso kwakaoma, uye workpiece Kuora kwemichina yekushandisa uye zvigadziriso zvagara zviri musoro.
Kakawanda, mativi ose maviri eplate heat exchanger ane zvinhu zvakaoma zvikuru izvo dzimwe nguva zvisingagoneki kutsika uye machining, asi zvinowanikwa nyore nyore kushandisa PCE.Kuwedzera, PCE inogona kugadzira zvinhu kumativi ose eplate panguva imwe chete, kuchengetedza nguva inokosha, uye nzira yacho inogona kushandiswa kune zvakasiyana-siyana zvesimbi, kusanganisira simbi isina tsvina, Inconel 617, uye titanium.
Nekuda kwehumwe hunhu hwekuita, PCE inopa imwe nzira inoyevedza yekutsikirira uye machining musheet metal application.Kushandisa photoresist uye etchant kunyatsogadzirisa chemikemikari nzvimbo dzakasarudzwa, iyo nzira inoratidzira yakachengetedzwa zvinhu, burr- uye-isina kushushikana zvikamu zvine yakachena contours uye pasina kupisa-kukanganisa nzvimbo. Uyezve, iyo fluid etching medium medium inoshandiswa mune inotonhorera chimiro inogadzira iyo inotonhorera dhizaini. makona nemacheto zvinogona kuita ngura.
Yakabatanidzwa nekuti PCE inoshandisa zviri nyore kudzokororwa uye inodhura madhijitari kana magirazi maturusi, inopa inodhura-inoshanda, yakakwirira-yakarurama uye inokurumidza kugadzira imwe nzira kune echinyakare machining matekiniki uye stamping.Izvi zvinoreva mari yakakosha yekuchengetedza pakugadzira zvishandiso zveprototype, uye kusiyana nekutsika uye machining maitiro, hapana chidzitiro chekupfeka uye mutengo unobatanidzwa nekuchekazve simbi.
Machining uye stamping zvinogona kuburitsa zvishoma-kupfuura-zvakakwana mhedzisiro pasimbi pamutsetse wakachekwa, kazhinji kukanganisa zvinhu zviri kugadzirwa uye kusiya maburrs, nzvimbo dzakakanganiswa nekupisa, uye recast layers.Kuwedzera, vanoedza kusangana netsananguro yetsanangudzo inodiwa kune zvidiki, zvakanyanya kuoma, uye zvakanyatsojeka simbi zvikamu zvakaita semarata ekutsinhana kupisa.
Chimwe chinhu chinofanira kutariswa mukusarudzwa kwemaitiro ndiko kuwanda kwezvinhu zvichaitwa machined.Maitiro echinyakare anowanzosangana nematambudziko kana akaiswa kune yakaonda simbi kugadzirisa, kutsika uye kutsika mune dzakawanda zviitiko zvisina kukodzera, nepo laser uye kucheka kwemvura kunotungamirira kune zvisingaenzaniswi uye zvisingagamuchirwi mazinga ekupisa kwekupisa uye kupatsanurwa kwezvinhu, zvichiteerana.Kunyange zvazvo PCE inogona kushandiswa mumhando dzakasiyana-siyana dzesimbi, iyo inogona kushandiswa pane zvakasiyana-siyana zvesimbi. zvakadai seaya anoshandiswa muplate heat exchangers, pasina kukanganisa flatness, iyo inokosha kune kuvimbika kwegungano. zvakakosha.
Nzvimbo yakakosha iyo mahwendefa anoshandiswa mumafuta emafuta ekushandisa akagadzirwa nesimbi isina tsvina, aruminiyamu, nickel, titanium, mhangura uye huwandu hwehunyanzvi alloys.
Metal mahwendefa mumasero emafuta akawanikwa aine zvakawanda zvakanakira pane zvimwe zvinhu. Panguva imwecheteyo, yakasimba kwazvo, inopa yakanakisa magetsi conductivity yekutonhodza zviri nani, inogona kugadzirwa yakanyanyisa kutetepa uchishandisa etching, zvichikonzera mapfupi akaturikidzana, uye isina inotungamira pamusoro pekupedzisira mukati mechannel.Plates inogona kuumbwa uye migero yakasikwa panguva imwe chete, uye sezvataurwa pamusoro apa, hapana thermal stress inogadzirwa mumhepo inodziya, inokonzeresa kushushikana kwesimbi.
Iyo PCE maitiro anovimbisa kudzokororwa kushivirira pane ese makiyi bhodhi zviyero, kusanganisira kudzika kwemhepo uye manifold geometry, uye inogona kugadzira zvikamu kune yakasimba kudonhedza kudonhedza zvakatemwa.
Mamwe maindasitiri anoshandisa mashizha emakemikari akaiswa mashizha anosanganisira linear motors, aerospace, petrochemical and chemical industries.Mushure mekugadzirwa, mahwendefa akaiswa uye kupararira kwakabatanidzwa kana kusungirirwa pamwe chete kuti aite musimboti wekupisa kupisa.Kupedza kupisa kunopisa kunogona kusvika katanhatu kuduku kudarika tsika dzechinyakare "shell uye chubhu" zvinopisa uremu, zvichipa nzvimbo yakanakisisa yekupisa.
Heat exchangers inogadzirwa nePCE zvakare yakasimba kwazvo uye inoshanda, inokwanisa kutsungirira kumanikidzwa kwe600 bar ichichinjika kune tembiricha kubva ku cryogenics kusvika ku900 degrees Celsius. Zvinogoneka kusanganisa hova dzinopfuura mbiri dzekuita muchikamu chimwe chete uye kusangana nezvinodiwa papombi uye mavharuvhu zvakaderedzwa zvakanyanya.Reaction uye kusanganisa kunogona zvakare kubatanidzwa mune imwe plated-effective dhizaini, inodhura inodhura.
Mazuva ano zvinodikanwa zvekushanda uye kuchengetedza nzvimbo yekupisa kupisa zvinopa matambudziko akakura kune akawanda mainjiniya ebudiriro.Kuita miniaturization yezvikamu zvakawanda mumagetsi uye microsystem tekinoroji inogadzira izvo zvinonzi zvinopisa zvinopisa, izvo zvinoda optimal kupisa kupisa kuti ive nechokwadi chehupenyu hurefu hwebasa.
Kushandisa 2D uye 3D PCE, microchannels ine hupamhi hunotsanangurwa uye yakadzika inogona kugadzirwa mumagetsi ekupisa kwekusarudzwa kwekupisa kupisa nhepfenyuro munzvimbo duku.Kunenge kusina muganhu kune zvingaita magadzirirwo emagetsi.
Uyezve, sezvo etching muitiro inokurudzira dhizaini utsanzi uye geometric rusununguko, mhirizhonga kuyerera kunopesana nelaminar kuyerera kunogona kusimudzirwa kuburikidza nekushandiswa kwewavy chiteshi kumicheto uye yakadzika.Turbulent inoyerera mumhepo inotonhorera inoreva kuti iyo inotonhorera inosangana nemhepo inopisa inogara ichichinja, izvo zvinoita kuti kupisa kwekushisa kuve kunobudirira.Such corrugations mukutsinhanisa uye irregulari yePC, inogadzirwa nyore nyore nePC. zvinokwanisika kana kudhura-kurambidza kugadzira uchishandisa mamwe maitiro ekugadzira.
