Kuthiwani ngokusebenza kwe-skived fin heat sink?

Usinki wokushisa we-skived finluhlobo lwesinki lokushisa elinamaphiko asikwa entweni eqinile.Ama-fin kusinki wokushisa we-skived fin mancane kakhulu uma kuqhathaniswaezinye izinhlobo zamasinki okushisa, njengaamasinki okushisa e-extrusion.Amasinki okushisa e-skived fin enziwa inqubo yokukhiqiza ebizwa ngokuthi i-skiving, ekhiqizwa umshini wokushushuluza onembayo onemba ebukhali elawulwa ngokunembile, yasika ucezu oluncane logqinsi olucacisiwe kulo lonke ucezu lwephrofayili yensimbi (AL6063 noma i-C1100 yethusi), bese igoba. ucezu oluncane lwensimbi oluma mpo ukuze lwenza ama-fin sinki okushisa.I-skived fin heat sink inikeza ukusebenza kahle okuphezulu kokushisa ezinhlelweni zokusebenza zamandla aphezulu.Lolu hlobo lukasinki wokushisa lunikeza izinzuzo ezifana nokumelana nokushisa okuncane, izindlela ezimfushane zokudlulisa ukushisa, nosayizi ohlangene.Ngezansi kunezincazelo ezinemininingwane yokusebenza kwamasinki okushisa e-skived fin kusuka kumibono eminingi.

1.I-Thermal Resistance: Ukumelana nokushisa kuchazwa njengomehluko wezinga lokushisa phakathi komthombo wokushisa nendawo ezungezile, ehlukaniswa yi-thermal flux, noma izinga lokudlulisa ukushisa, ngokusebenzisa usinki wokushisa:

Rth = (Tsource - Tambient) / Q

lapho i-Rth = ukumelana nokushisa (ngamadigri Celsius nge-Watt ngayinye), i-Tsource = izinga lokushisa lomthombo wokushisa, i-Tambient = izinga lokushisa lendawo ezungezile, kanye no-Q = ukushisa okushisayo (ngama-Watts).

Umbukiso wamasinki okushisa acwebileukumelana nokushisa okuphansi, okuyisilinganiso sokuthi usinki wokushisa udlulisela ngempumelelo kangakanani ukushisa kusuka emthonjeni kuya endaweni ezungezile.I-skived fin heat sink inendawo enkulu endaweni yevolumu yesilinganiso kuneamasinki okushisa e-extrusion, okubenza basebenze kahle ekukhipheni ukushisa.

2. Ukukhipha Ukushisa: Ngenxa yokuthi amaphiko okugwedla anezindonga ezincane kakhulu uma kuqhathaniswa nama-fins angaphandle, okuholela endaweni enkulu yokudlulisa ukushisa.Amasinki okushisa ama-skiving anendawo enkulu kakhulu uma kuqhathaniswa namasinki okushisa e-extrusion, angakhipha ukushisa okwengeziwe.I-skived fins inendawo enkulu yokuxhumana nomthombo wokushisa, okuholela ekutheniukuchithwa kokushisa okuphezulu.Inqubo yokushushuluza iphinde ivumele ukuguquguquka okukhulu ekuklameni i-fin geometry, okuvumela ukudluliswa kokushisa okuphumelelayo.

3. Isisindo nosayizi: Osinki bokushisa bama-skived fin abajwayelekileelula futhi encanekunezinye izinhlobo zamasinki okushisa.Lokhu kuzenza zilungele ukusetshenziswa kumishini emincane kagesi enesikhala esilinganiselwe esitholakalayo sezinhlelo zokupholisa.

4. Ubunkimbinkimbi bokukhiqiza: Ukwenziwa kosinki wokushisa okushushumbisiwe kuyikhoeyinkimbinkimbi futhi ebiza kakhuluuma kuqhathaniswa nokukhiqizwa kukasinki wokushisa we-extrusion.Ukukhiqiza osinki bokushisa be-skived fin kudinga okokusebenza okukhethekile kanye nomsebenzi onekhono.Ngakho skived fin ukushisa usinki kuyintoilungele kakhulu inani elincane le-oda.

5. Ukumelana Nokugqwala: Osinki bokushisa amaphiko abashushuluziwe abenziwe nge-aluminium noma ngethusi bangagqwala lapho bechayeke kumakhemikhali, umswakama, noma ezinye izici zemvelo., ngakho-ke sivamise ukudinga ukubenzela ukwelashwa okungaphezulu, amasinki okushisa e-skived fin anjaloembozwe ungqimba lwezinto zokuzivikelaukuvimbela ukugqwala.

Sekukonke, usinki wokushisa we-skived fin uklanyelwe ukunciphisa ukumelana nokushisa, okuholela ekutheniukuchithwa kokushisa okusebenzayokanye namazinga okushisa aphansi emthonjeni wokushisa.Ukumelana okushisayo kwe-skived fin heat sink kuthonywa izici ezifana ne-fin geometry, izakhiwo zezinto ezibonakalayo, nesimo sokusebenza osinki bokushisa be-skived fin baziwa ngezabo.ukusebenza kahle okuphezulu kokushisa kanye nosayizi ohlangene, okuzenza zilungele ukusetshenziswa ezinhlelweni zamandla aphezulu anendawo elinganiselwe yezinhlelo zokupholisa.
