Daim ntawv qhia rau Radiator Mounted Hwj chim zaj duab xis resistors
Paub qhov kub thiab lub zog ntsuas:

Daim duab 1-to taub qhov ntsuas kub thiab lub zog ntsuas
Kev sib dhos ntawm cov khoom siv cua sov:
1, Muaj qhov sib txawv vim qhov kev hloov pauv ntawm qhov chaw sib txuas ntawm lub pob resistor thiab lub tshuab hluav taws xob.Cov voids no yuav txo tau qhov kev ua tau zoo ntawm cov cuab yeej TO-hom.Yog li ntawd, kev siv cov khoom siv thermal interface los ua kom cov pa tawm no yog qhov tseem ceeb heev.Ntau cov ntaub ntawv tuaj yeem siv los txo cov thermal tsis kam ntawm cov resistor thiab radiator nto.
2, Thaum tshav kub kub-conducting silicone roj yog kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob thiab cov kua dej uas ua ke los ua kom muaj kev sib xws zoo ib yam li cov roj.Cov kua no feem ntau yog cov roj silicone, tab sis tam sim no muaj qhov zoo heev "Non-silicon" tshav kub conductive silicone roj.Thermally conductive silicone resins tau siv ntau xyoo thiab feem ntau muaj qhov qis tshaj thermal tsis kam ntawm tag nrho cov khoom siv thermally conductive.
3, Cov khoom siv hluav taws xob kub yog cov khoom siv hluav taws xob ua hluav taws xob thiab muaj los ntawm ntau lub tuam txhab.Cov ntaub qhwv no muaj ib daim ntawv lossis cov ntawv txiav ua ntej thiab yog tsim los rau ntau hom pob khoom xws li TO-220 thiab To-247.Lub tshav kub conduction gasket yog cov khoom siv spongy, xav tau lub siab sib xws thiab kev ua haujlwm ruaj khov kom ua haujlwm tau zoo.
Kev xaiv cov khoom siv kho vajtse:
Cov khoom kho kom zoo yog qhov tseem ceeb heev hauv kev tsim kom txias txias.Cov khoom siv kho vajtse yuav tsum muaj lub zog ruaj khov thiab zoo ib yam ntawm cov cuab yeej siv los ntawm kev siv thermal cycling tsis cuam tshuam lub radiator lossis cov khoom siv.
Ntau tus neeg tsim qauv nyiam txuas lub DeMint TO lub zog tiv thaiv rau lub tshuab hluav taws xob siv lub caij nplooj ntoos hlav clip es tsis txhob siv cov ntsia hlau sib dhos.Cov clips caij nplooj ntoos hlav no muaj los ntawm ntau lub tuam txhab uas muab ntau tus qauv springs thiab radiators tsim tshwj xeeb rau clip mounting hauv TO-220 thiab To-247 pob.Lub caij nplooj ntoos hlav clamp muaj ntau yam zoo uas yooj yim rau kev sib sau ua ke, tab sis nws qhov zoo tshaj plaws yog tias nws siv lub zog zoo tshaj plaws nyob rau hauv nruab nrab ntawm lub hwj chim resistor (saib daim duab 2)

Daim duab 3-screw thiab washer mounting txheej txheem
Screw Mounting-belleville los yog tapered washers siv nrog screws yog ib txoj hauv kev zoo los txuas rau lub tshuab hluav taws xob.Belleville washers yog tapered caij nplooj ntoos hlav ntxhua khaub ncaws tsim los tswj lub siab tsis tu ncua ntawm ntau yam deflection.Gaskets tuaj yeem tiv taus qhov kub thiab txias mus ntev yam tsis muaj kev hloov siab.Daim duab 3 qhia txog qee qhov kev teeb tsa kho vajtse rau kev teeb tsa TO pob ntsia hlau rau lub tshuab hluav taws xob.Cov tshuab ntxhua khaub ncaws, lub hnub qub ntxhua khaub ncaws, thiab cov tshuab ntxhua khaub ncaws feem ntau yuav tsum tsis txhob siv rau hauv qhov chaw ntawm Belleville ntxhua khaub ncaws vim lawv tsis muab lub siab mounting tas li thiab tej zaum yuav ua rau cov resistor puas.
Cov ntawv sau ua ke:
1, Tsis txhob siv TO series lub zog resistors hauv SMT cov rooj sib txoos.
2, Yas mounting hardware uas softens los yog creep ntawm kev khiav hauj lwm kub yuav tsum tau zam
3, Tsis txhob cia lub taub hau ntsia hlau kov lub resistor.Siv cov tshuab ntxhua khaub ncaws los yog cov tshuab ntxhua khaub ncaws kom sib npaug sib npaug
4, zam cov ntawv hlau ntsia hlau, uas zoo li dov cov npoo ntawm lub qhov thiab tsim kev puas tsuaj burrs hauv lub tshuab hluav taws xob
5, Rivets tsis pom zoo.Kev siv cov rivets yog qhov nyuaj los tswj kom muaj kev sib haum xeeb thiab tuaj yeem ua rau cov ntim yas yooj yim puas
6, Tsis txhob overdo lub torque.Yog tias cov ntsia hlau nruj dhau lawm, lub pob yuav tawg ntawm qhov kawg ntawm qhov kawg ntawm cov ntsia hlau (qhov kawg ntawm cov hlau lead) los yog muaj kev nyiam khoov rau sab saud.Cov cuab yeej pneumatic tsis pom zoo.
