For electronic equipment, there will be a certain amount of heat when working, so that the internal temperature of the equipment rises rapidly. If the heat is not emitted in time, the equipment will continue to heat up, the device will fail because of overheating, and the reliable performance of electronic equipment will decline. Chifukwa chake, ndikofunikira kwambiri kuchititsa chithandizo chabwino cha kutentha kwa kutentha kwa bolodi.

1. Kutentha kwazitsulo zamkuwa ndikugwiritsa ntchito malo akulu opangira zida zamkuwa.

Malinga ndi chithunzi pamwambapa, kukula kwa dera lolumikizana ndi khungu lamkuwa, kumachepetsa kutentha kwa mphambano

Malinga ndi chithunzi pamwambapa, titha kuwona kuti kukulira kwa mkuwa wokutira, kumachepetsa kutentha kwa mphambano.

2. Bowo lotentha

Dzenje lotentha limatha kuchepetsa kulumikizana kwa chipangizocho, kukonza kufanana kwa kutentha komwe kumayang’ana bolodi la bolodi, ndikupatsanso mwayi wogwiritsa ntchito njira zina zozizirira kumbuyo kwa PCB. Zotsatira zoyeserera zikuwonetsa kuti kutentha kwa mphambano kumatha kuchepetsedwa pafupifupi 4.8 ° C pomwe mphamvu yamafuta yamagetsi ndi 2.5W, mpata ndi 1mm, ndipo kapangidwe kake kali 6 × 6. Kusiyana kutentha pakati pa pamwamba ndi pansi pa PCB yafupika kuchokera 21 ° C mpaka 5 ° C. Kutentha kwa mphindikati kwa chipangizocho kumawonjezeka ndi 2.2 ° C poyerekeza ndi 6 × 6 pambuyo poti dzenje lotentha lasinthidwa kukhala 4 × 4.

3. IC kumbuyo yowululidwa mkuwa, kuchepetsa kutentha kwa kutentha pakati pa khungu lamkuwa ndi mpweya

4. Makhalidwe a PCB

Zofunikira zamagetsi apamwamba, zamagetsi.

A. Zipangizo zotentha ziyenera kuikidwa m’dera lozizira la mphepo.

B. Chida chodziwira kutentha chiyenera kuyikidwa pamalo otentha kwambiri.

C. Zipangizo zomwe zidasindikizidwa chimodzimodzi ziyenera kukonzedwa momwe zingathere malinga ndi kuchuluka kwake kwakatundu ndi kutentha kwake. Zipangizo zomwe zimakhala ndi ma calorific otsika kapena kukana kutentha pang’ono (monga ma transistors ang’onoang’ono, ma circuits ang’onoang’ono ophatikizika, ma electrolytic capacitors, ndi zina zambiri) ziyenera kuyikidwa kumtunda (kolowera) kwa mpweya wozizira. Zipangizo zokhala ndi ma calorific apamwamba kapena kutentha kwabwino (monga ma transistors amagetsi, ma circuits akuluakulu ophatikizika, ndi zina zambiri) zimayikidwa kumapeto kwenikweni kwa mpweya wozizira.

D. Munjira yopingasa, zida zamagetsi zazikulu ziyenera kukonzedwa pafupi ndi m’mphepete mwa bolodi kuti zifupikitse njira yosinthira kutentha; Kumbali yowongoka, zida zamagetsi zamagetsi zimakonzedwa pafupi kwambiri ndi bolodi losindikizidwa, kuti muchepetse kukhudzidwa kwa zida izi pamatenthedwe azida zina zikagwira ntchito.

E. Kutaya kwanyumba kwa makina osindikizidwa mu zida makamaka kumadalira kutuluka kwa mpweya, kotero ndikofunikira kuphunzira njira yolowera ndi kukonza zida moyenera kapena mabatani azisindikizo pamapangidwe. Kutuluka kwa mpweya nthawi zonse kumayenderera pomwe kulimbana kuli kocheperako, chifukwa chake mukamapanga zida zama board osindikizidwa, pewani kukhala ndi malo akulu ampweya m’dera linalake. Kukhazikitsidwa kwa matabwa angapo osindikizidwa pamakina onse kuyenera kulabadira vuto lomwelo.

F. chida chodziwitsa kutentha chimayikidwa bwino pamalo otentha kwambiri (monga pansi pa zida), osayiika pazida zotenthetsera zili pamwambapa, zida zingapo ndizoyendetsedwa bwino pa ndege yopingasa.

G. Ikani zida zogwiritsira ntchito kwambiri komanso zotenthetsera kwambiri pafupi ndi malo abwino kwambiri otenthetsera kutentha. Osayika zida zotentha m’makona ndi m’mbali mwa bolodi pokhapokha pali chozizira pafupi nacho. Pakapangidwe kazolimbana ndi mphamvu zazikulu momwe zingathere kuti musankhe chida chokulirapo, ndikusintha kapangidwe kamakina osindikizidwa kuti pakhale malo okwanira kutaya kwanyengo.

Katchulidwe kakang’ono ka zigawo:
