Njira ya Brazing ya Plate-Fin Heat Exchangers

Mawu Oyamba

Plate-fin heat exchangers (PFHEs) ndi ofunikira m'mafakitale monga magalimoto, ndege, ndi cryogenics. Zida zophatikizika, zogwira mtima izi zimasamutsa kutentha pakati pa zamadzimadzi kwinaku zikusunga chinsinsi komanso kuchepetsa kutsika kwamphamvu. Nkhaniyi ikuyang'ana njira yomwe imagwiritsidwa ntchito popanga ma PFHE, ndikugogomezera kufunika kwake ndi ubwino wake.

Vacuum Brazing: Njira Yotsimikiziridwa

Ku Wuxi Jiushengyuan Science & Technology Co., Ltd. (KIUSIN), timagwiritsa ntchito ukadaulo wa vacuum brazing kupanga ma PFHE apamwamba kwambiri. Nazi mwachidule za ndondomekoyi:

1.Plate Assembly: Chigawo cha PFHE chimakhala ndi mbale zosinthana ndi zipsepse, mbale iliyonse yokutidwa ndi filimu yopyapyala yazitsulo zamkuwa kumbali zonse ziwiri. Kuyanjanitsa kolondola kwa zipsepsezo kumatsimikizirika panthawi yosonkhanitsa mosamala.

2.Nyumba ya Vacuum: Chida chosonkhanitsidwa cha PFHE chimayikidwa mu ng'anjo yopanda vacuum. The brazing ndondomeko kumachitika pansi vacuum mikhalidwe, kuthetsa kufunika flux. Kutentha kwa ng'anjo kumafika pafupifupi 580 ° C.

3.Kuwombera: Panthawi yowotcha, chitsulo chachitsulo chimasungunuka ndikuyenda, kupanga zomangira zolimba pakati pa mbale zoyandikana. Zigawo za chipikacho zimamangirizidwa mwamphamvu, kupanga dongosolo lolimba.

4. Zowonjezera: Pambuyo-brazing, zina zowonjezera monga mitu ya chitoliro cha theka, ma nozzles, mabatani othandizira, ndi ma trunnions okweza amawotcherera pakatikati, kupititsa patsogolo ntchito ndi kutuluka kwamadzimadzi mkati mwa PFHE.

Ubwino wa Vacuum Brazing

1. Kusindikiza kwa Hermetic: Vacuum brazing imatsimikizira kuti chisindikizo chosasunthika, chofunikira kwambiri pakugwiritsa ntchito cryogenic pomwe kutentha kumakhala kofunikira.

2.Uniform Heat Distribution: Malo otetezedwa a vacuum ng'anjo amalola kutentha yunifolomu, kuchepetsa kupsinjika kwa kutentha ndi kusokoneza.

3.Oyera ndi Opanda Flux: Mosiyana ndi njira zachikhalidwe zowotcha, kupukuta kwa vacuum sikufuna kusinthasintha, kuthetsa kufunika kotsuka pambuyo poyatsa ndi kuchepetsa chiopsezo cha kuipitsidwa.

4.Mkulu-Mphamvu Mgwirizano: Zomangira zachitsulo zomwe zimapangidwa panthawi ya vacuum brazing zimabweretsa mafupa amphamvu, olimba omwe amatha kupirira kupsinjika kwakukulu komanso kusiyana kwa kutentha.

Mapeto

Monga wopanga PFHE wotsogola, KIUSIN imaphatikiza ukatswiri, ukadaulo wapamwamba, komanso kudzipereka pakuchita bwino. Ma PFHE athu okhala ndi vacuum-brazed amaphimba kutentha kwakukulu ndikupirira kupsinjika mpaka 130 bar. Kaya ndi ma radiator amagalimoto, ma compressor a mpweya, kapena makina a cryogenic, ma PFHE athu amapereka kutentha koyenera komanso kudalirika.

Kuti mumve zambiri, pitani patsamba lathu lovomerezeka kapena funsani akatswiri athu lero!
