Izitshintshi zobushushu zePlate zikhona kwizicelo ezininzi zemizi-mveliso kwaye ngokuyintloko zisebenzisa iipleyiti zentsimbi ukuhambisa ubushushu phakathi kolwelo ezimbini.
Ukusetyenziswa kwazo kukhula ngokukhawuleza ngenxa yokuba zigqithisa izinto zokushisa zendabuko (ngokuqhelekileyo ityhubhu edibeneyo equlethe ulwelo olunye oludlula kwigumbi elinolunye ulwelo) ngenxa yokuba ulwelo olupholiswayo luqhagamshelwano oluphezulu lwendawo, eyenza ukuhanjiswa kobushushu kwaye kwandisa kakhulu izinga lokutshintsha kobushushu.
Endaweni yeekhoyili ezidlula kumagumbi, kwi-plate exchanger heat exchanger, kukho amagumbi amabini atshintshanayo, ngokuqhelekileyo anobunzulu obuncinci, ahlulwe ngamacangci ensimbi enqabileyo kwiindawo zawo ezinkulu.
Iipleyiti zokutshintshiselana ngobushushu ngokwesiqhelo zenziwe kusetyenziswa isitampu okanye umatshini oqhelekileyo onjengomzobo onzulu, kodwa mva nje ukufakwa kwefotochemical (PCE) kungqineke yeyona ndlela yolwakhiwo isebenzayo nengabizi kakhulu ekhoyo kwesi sicelo singqongqo.Electrochemical Machining (ECM) bobunye ubuchwephesha obunokuvelisa iinxalenye ezichanekileyo kakhulu kwiibhetshi, kodwa le nkqubo ifuna utyalo-mali oluphezulu kakhulu, isebenzise amandla amaninzi, isebenzise imveliso yamandla ephezulu. uyilo kunye nokuveliswa kwezixhobo kunzima, kwaye i-workpiece I-corrosion yezixhobo zoomatshini kunye nezixhobo zihlala yintloko.
Ngokuqhelekileyo, macala omabini e-plate heat exchanger aqulethe izinto ezinzima kakhulu ezinokuthi ngamanye amaxesha zigqithise amandla e-stamping kunye ne-machining, kodwa zifikeleleka ngokulula ngokusebenzisa i-PCE.Ukongezelela, i-PCE inokuvelisa iimpawu kumacala omabini epleyiti ngaxeshanye, igcina ixesha elibalulekileyo, kwaye inkqubo ingasetyenziswa kuluhlu lwezinyithi ezahlukeneyo, kubandakanywa insimbi engenasici, i-Inconel 617 kunye ne-titanium.
Ngenxa yeempawu ezithile zendalo zenkqubo, i-PCE ibonelela ngenye indlela enomtsalane yokunyathela kunye nomatshini kwizicelo zesinyithi. Ukusebenzisa ifotoresist kunye ne-etchant ukusetyenzwa ngokuchanekileyo ngokwekhemikhali iindawo ezikhethiweyo, inkqubo ineempawu ezigciniweyo zezinto eziphathekayo, iinxalenye ze-burr- kunye ne-stress-free kunye ne-contours ecocekileyo kwaye akukho mimandla echaphazelekayo yokushisa. iikona kunye nemiphetho esengozini yokubola.
Idityaniswe nenyaniso yokuba i-PCE isebenzisa izixhobo eziphindaphindwayo kunye nexabiso eliphantsi ledijithali okanye izixhobo zeglasi, ibonelela ngexabiso elifanelekileyo, ukuchaneka okuphezulu kunye nokukhawuleza ukuvelisa enye indlela yokwenziwa kweendlela zemveli kunye ne-stamping.Oku kuthetha ukonga okubalulekileyo kweendleko xa kuveliswa izixhobo zeprototype, kwaye ngokungafaniyo nesitampu kunye nobuchule bomatshini, akukho mpahla yokunxiba kunye neendleko ezinxulumene nentsimbi yokusika kwakhona.
Ukutshiza kunye nesitampu kunokuvelisa iziphumo ezingaphantsi kunezo-ezigqibeleleyo kwintsimbi kumgca wokusikwa, ngokufuthi ukuguqula izinto eziphathekayo kunye nokushiya i-burrs, imimandla echaphazelekayo kubushushu, kunye neengqimba eziphindwe kabini.
Enye into ekufuneka iqwalaselwe ekukhetheni inkqubo bubunzima bezinto eziza kwenziwa ngomatshini.Iinkqubo zemveli zihlala zihlangabezana nobunzima xa zisetyenziselwa ukucutshungulwa kwesinyithi esicekethekileyo, ukunyathela kunye nokunyathela kwiimeko ezininzi azifanelekanga, ngelixa ukusika kwe-laser kunye namanzi kukhokelela kumanqanaba angafaniyo kunye angamkelekanga okutshintsha kwe-thermal kunye nokuqhekeka kwezinto, ngokulandelanayo.Ngelixa i-PCE ingasetyenziswa kwi-intlobo ngeentlobo zetsiti zetsimbi zetsimbi zetsimbi, zinokuthi zisebenzise ubuninzi be-metal. ezifana nezo zisetyenziselwa ukutshintshiselana kobushushu bepleyiti, ngaphandle kokunciphisa i-flatness, ebaluleke kakhulu kwingqibelelo yendibano. kubalulekile.
Indawo ephambili apho iipleyiti zisetyenziselwa ukusetyenziswa kweeseli ze-fuel ezenziwe ngensimbi engenasici, i-aluminium, i-nickel, i-titanium, ithusi kunye noluhlu lwe-alloys ekhethekileyo.
Iipleyiti zesinyithi kwiiseli zamafutha ziye zafunyanwa zineenzuzo ezininzi ngaphezu kwezinye izinto.Ngexesha elifanayo, zinamandla kakhulu, zinika umbane obalaseleyo wokupholisa ngcono, zingenziwa zenziwe zincinci kakhulu ngokusebenzisa i-etching, ibangele i-stacks emfutshane, kwaye ayinayo isiphelo somphezulu we-directional ngaphakathi kwe-channel.Plates inokuqulunqwa kunye nemijelo eyenziwe ngaxeshanye, kwaye njengoko kukhankanyiwe ngasentla, akukho xinzelelo lwe-thermal ensuringen ludalwe kwi-thermal, i-flat ensuring ye-thermal.
Inkqubo yePCE iqinisekisa ukunyamezelana okuphinda-phindayo kuyo yonke imilinganiselo yebhodi engundoqo, kuquka ubunzulu bomoya kunye nejiyometri eninzi, kwaye inokuvelisa iinxalenye kuxinzelelo oluqinileyo lokulahla iinkcukacha.
Amanye amashishini asebenzisa amaphepha afakwe kwiikhemikhali abandakanya iimoto ezinqamlekileyo, i-aerospace, i-petrochemical kunye ne-chemical industries.Emva kokuveliswa, iiplate zixutywe kwaye zixutywe ziboshwe okanye ziboshwe kunye ukuze zenze i-core of the heat exchanger.I-heat exchangers egqityiweyo ingaba ngamaxesha amathandathu amancinci kuneenzuzo zendabuko "igobolondo kunye ne-tube" yokulinganisa ubushushu, inika indawo egqwesileyo.
Abatshintshi bokushisa abaveliswa ngokusebenzisa i-PCE nabo banamandla kakhulu kwaye basebenza kakuhle, bayakwazi ukumelana noxinzelelo lwe-bar ye-600 ngelixa belungelelanisa kuluhlu lobushushu ukusuka kwi-cryogenics ukuya kwi-900 degrees Celsius.Kunokwenzeka ukudibanisa imisinga yenkqubo engaphezu kwembini ibe yiyunithi enye kwaye ihlangabezane neemfuno kwimibhobho kunye neevalvu ziyancitshiswa kakhulu.
Iimfuno zanamhlanje zokutshatyalaliswa kobushushu ngokufanelekileyo kunye nendawo zinika imingeni enkulu kwiinjineli ezininzi zophuhliso.I-miniaturization yamacandelo amaninzi kubuchwepheshe bombane kunye ne-microsystem idala iindawo ezibizwa ngokuba yi-thermal hot spots, ezifuna ukuchithwa kobushushu obufanelekileyo ukuqinisekisa ubomi obude benkonzo.
Ukusebenzisa i-2D kunye ne-3D PCE, i-microchannels enobubanzi obuchaziweyo kunye nobunzulu bunokuthi yenziwe kwi-heat exchangers ekukhethweni kweendaba zokutshatyalaliswa kobushushu kwindawo encinci.Kukho phantse akukho mda kwiindlela ezinokwenzeka zokuyila.
Ngaphezu koko, ekubeni inkqubo etching ikhuthaza ukuyila ngokutsha kunye nenkululeko yejometri, ukuhamba kwesiphithiphithi ngokuchasene nokuhamba kwe-laminar kunokukhuthazwa ngokusebenzisa i-wavy channel edges kunye ne-deeps.Ukuhamba kwe-turbulent kwindawo yokupholisa kuthetha ukuba i-coolant idibene nomthombo wobushushu ihlala iguquka, eyenza utshintshiselwano lobushushu lube lusebenza ngakumbi. kunokwenzeka okanye kuthintelwe iindleko zokuvelisa kusetyenziswa ezinye iinkqubo zokuvelisa.
Ingcali ye-PCE i-micrometal GmbH isebenzisa izixhobo ze-optoelectronic ezinexabiso elikhuphisanayo ukuvelisa izixhobo zokusebenza ezikumgangatho ophezulu ezinenqanaba eliphezulu lokuchaneka okuphindaphindwayo.
Iipleyiti ze-microchannel ezizimeleyo zinokudityaniswa (umzekelo, ngokudibanisa i-welding) kwiijometri ezahlukeneyo ze-3D.micrometal isebenzisa inethiwekhi yeqabane elinamava elinika abathengi ithuba lokuthenga iipleyiti ze-microchannel okanye iibhloko zokutshintshiselana kobushushu.
Into eneempawu zetsimbi kwaye iqulathe iikhemikhali ezimbini okanye ngaphezulu, enye yazo ibe yintsimbi.
Nciphisa ukunyuka kwamaqondo obushushu obumanzi kwisixhobo/i-workpiece interface ngexesha le-machining. Ngokwesiqhelo kwimo yolwelo, efana ne-soluble okanye imixube yeekhemikhali (semi-synthetic, synthetic), kodwa inokuba noxinzelelo lomoya okanye ezinye iigesi. i-semi-synthetic cutting fluid; ulwelo lokusika ioyile enyibilikayo; i-synthetic cutting fluid.
1. Ukwabiwa kwecandelo kwigesi, ulwelo, okanye okuqinileyo okukholisa ukwenza ukwakheka kufane kuzo zonke iindawo.2. Iathomu okanye iathom isuka ihambe ngokuzenzekelayo iye kwindawo entsha ngaphakathi kwezinto.
Umsebenzi apho umbane ohamba khona phakathi kwendawo yokusebenza kunye nesixhobo sokuqhuba ngokusebenzisa i-electrolyte.Iqala ukuphendulwa kweekhemikhali ezinyibilikisa isinyithi kwi-workpiece kwizinga elilawulwayo.Ngokungafaniyo neendlela eziqhelekileyo zokusika, ukuqina kwe-workpiece ayisiyonto, okwenza i-ECM ilungele izinto ezinzima-kumatshini.Ngendlela yokugaya i-electrochemical, i-electrochemical honing kunye ne-electrochemical turning.
Ukusebenza ngokufana ne-motor rotary kwisixhobo somatshini, i-motor ye-linear inokucingwa njenge-motor ye-magnetic esisigxina ejikelezayo, inqunywe i-axially embindini, emva koko ihlulwe kwaye ibekwe flat.Inzuzo ephambili yokusebenzisa ii-motor ze-linear ukuqhuba i-axis motion kukuba iphelisa ukungasebenzi kakuhle kunye nokwahlukana komatshini okubangelwa yinkqubo yokuhlanganisa ibhola ye-screw esetyenziswa kwiindawo ezininzi ze-CNC.
Amalungu anezithuba eziphangaleleyo kubume bomphezulu. Bandakanya zonke izitenxo ezibekwe banzi kunolungiselelo lokusikwa kwesixhobo.Jonga ukuhamba; Ubuxoki; Uburhabaxa.
