Kutentha Kukwera kwa Bungwe Losindikizidwa Lozungulira

Chifukwa chachindunji cha kukwera kwa kutentha kwa PCB ndi chifukwa cha kukhalapo kwa zida zamagetsi zamagetsi, zida zamagetsi zimakhala ndi magawo osiyanasiyana amagetsi, komanso kutentha kwamphamvu kumasiyana ndi kutha kwa mphamvu.

2 zochitika za kukwera kwa kutentha mu PCB:

(1) kukwera kwa kutentha kwapafupi kapena kukwera kwakukulu kwa kutentha;

(2) kutentha kwanthawi yayitali kapena kwanthawi yayitali.

 

Pakuwunika mphamvu yamafuta a PCB, zinthu zotsatirazi zimawunikidwa nthawi zambiri:

 

1. Kugwiritsa ntchito mphamvu zamagetsi

(1) kusanthula kugwiritsa ntchito mphamvu pagawo lililonse;

(2) santhulani kugawa mphamvu pa PCB.

 

2. Kapangidwe ka PCB

(1) kukula kwa PCB;

(2) zipangizo.

 

3. Kuyika kwa PCB

(1) unsembe njira (monga unsembe ofukula ndi yopingasa unsembe);

(2) kusindikiza chikhalidwe ndi kutalika kwa nyumbayo.

 

4. Kutentha kwa kutentha

(1) radiation coefficient of PCB pamwamba;

(2) kusiyana kwa kutentha pakati pa PCB ndi malo oyandikana nawo ndi kutentha kwawo kwathunthu;

 

5. Kuwongolera kutentha

(1) kukhazikitsa radiator;

(2) kuchititsa zina unsembe nyumba.

 

6. Thermal convection

(1) kusuntha kwachilengedwe;

(2) kukakamiza kuziziritsa convection.

 

PCB kusanthula zinthu pamwamba ndi njira yabwino yothetsera kutentha kwa PCB kukwera, nthawi zambiri mu mankhwala ndi dongosolo zinthu zimenezi n'zogwirizana ndi amadalira, zinthu zambiri ayenera kusanthula malinga ndi mmene zinthu zilili, kokha chifukwa chenicheni chenicheni zinthu zikhoza kukhala zambiri. kuwerengetsera molondola kapena kukwera kwa kutentha ndi magawo amagetsi.
