Zvakanakira zvefinned tubes

Kuendesa kupisa kubva kumvura inopisa kupinda mumvura inotonhora kuburikidza nemadziro echubhu ndicho chikonzero vazhinji vedu tinoshandisa machubhu ane finned.Asi iwe unogona kubvunza, ndechipi chikuru chakanakira kushandisa chubhu yakabikwa?Sei usingakwanise kungoshandisa chubhu yenguva dzose kuita iyi kutamisa?Zvakanaka iwe unogona asi mwero uchave wakaderera zvakanyanya.

Nekusashandisa chubhu yakafinhwa nzvimbo yekunze haina kunyanya kukura kupfuura mukati menzvimbo.Nekuda kweizvozvo, iyo fluid ine yakaderera kupisa kupisa coefficient icharaira iyo yakazara kupisa mwero wekutamisa.Kana kupisa kwekutamisa coefficient yemvura mukati mechubhu yakakura kakawanda kupfuura iyo yemvura iri kunze kwechubhu huwandu hwese hwekupisa hunogona kuvandudzwa zvakanyanya nekuwedzera nzvimbo yekunze yechubhu.

Machubhu akacheneswa anowedzera kunze kwenzvimbo.Nekuva nechubhu yakagadziriswa munzvimbo, inowedzera huwandu hwese hwekupisa kupisa.Izvi zvinobva zvadzikira huwandu hwese hwemachubhu anodiwa kune yakapihwa application iyo inozodzikisawo saizi yemidziyo yese uye inogona mukufamba kwenguva kuderedza mutengo weprojekiti.Muzviitiko zvakawanda zvekushandisa, chubhu imwe yakafinhwa inotsiva matanhatu kana anopfuura asina machubhu asingasviki 1/3 mutengo uye 1/4 vhoriyamu.

Pazvikumbiro zvinosanganisira kutamiswa kwekupisa kubva kumvura inopisa kusvika kune inotonhora kuburikidza nemadziro echubhu, fin tubes inoshandiswa.Kazhinji, kune inopisa kupisa kwemhepo, uko imwe yemvura iri mhepo kana imwe gasi, iyo yemhepo yedivi remhepo kupisa coefficient ichave yakaderera zvakanyanya, saka yekuwedzera kupisa kupisa pamusoro penzvimbo kana fin chubhu exchanger inobatsira zvakanyanya.Iyo yakazara pateni kuyerera kweyakagadziriswa chubhu exchanger inowanzo kuyambuka, zvisinei, inogona zvakare kuenderana kuyerera kana kuyerera.

Fins inoshandiswa kuwedzera nzvimbo inoshanda yekupisa inopisa tubing.Uyezve, machubhu akacheneswa anoshandiswa kana iyo yekutamisa coefficient kunze kwechubhu yakadzikira zvakanyanya kupfuura iyo iri mukati.Mune mamwe mazwi, kupisa kunotamiswa kubva kumvura kuenda kugasi, mhute kuenda kune gasi, senge chiutsi kuenda kumhepo chinopisa chinopisa, uye thermic fluid kuenda kumhepo inopisa exchanger.

Mwero wekuti kupisa kwakadaro kunogona kuitika kunoenderana nezvinhu zvitatu - [1] musiyano wetembiricha pakati pemvura mbiri;[2] kupisa kwekutamisa coefficient pakati peimwe neimwe yemvura uye chubhu madziro;uye [3] nzvimbo yepamusoro iyo mvura yega yega inoratidzwa.

Machubhu akacheneswa anoshandiswa nekuti anobatsira

Wedzera Mwero weKutamisa Kupisa:

A finned tube exchanger anowanzo ane machubhu ane zvimbi zvakanamirwa kunze.Kazhinji, pachange paine mvura inoyerera nemukati memachubhu nemhepo kana imwe gasi inoyerera kunze kwemachubhu, uko kuwedzera kupisa kwepamusoro penzvimbo nekuda kwechubhu yakabikwa kunowedzera mwero wekupisa.Mune crossflow fin chubhu exchanger, zvimbi zvinenge zviri radial zvimbi uye zvinogona kunge zvakaita denderedzwa kana sikweya muchimiro.

Natsiridza Heat Transfer Coefficient:

Nekusashandisa chubhu yakagadziriswa, nzvimbo yekunze yekunze haina kunyanya kukura kupfuura mukati menzvimbo.Nekuda kweizvi, mvura ine yakaderera kupisa kweyekupisa coefficient inoraira iyo yakazara kupisa mwero.Kana kupisa kwekutamisa coefficient yemvura mukati mechubhu yakakura kakawanda kupfuura iyo yemvura iri kunze kwechubhu, huwandu hwese hwekupisa hunogona kuvandudzwa zvakanyanya nekuwedzera nzvimbo yekunze yechubhu.

Wedzera Kunze Kwenzvimbo Yepamusoro:

Nekuva nechubhu yakagadziriswa munzvimbo, inowedzera huwandu hwese hwekupisa kupisa.Machubhu akapedzwa anowedzera nzvimbo yekunze.Izvi zvinodzikisira huwandu hwese hwemachubhu anodiwa kune yakapihwa application iyo inozodzikisawo saizi yemidziyo yese uye inogona mukufamba kwenguva kuderedza mutengo weprojekiti.

 

Finned tube heat exchangers inoshandiswa mune zvakasiyana-siyana zvekushandisa, uye zvakanyanya semaindasitiri ekupisa kupisa.Mhepo yekupisa inotsinhanisa senge evaporator coil muair conditioning unit inowanzoita fin chubhu exchanger.Imwe yakajairika fin tube air heat exchanger ndiyo mota radiator.Chinangwa chemotokari yemotokari ndechekutonhodza mvura inopisa mumachubhu nemhepo inopfuura nemuchinjika.Pane zvinopesana, iyo air conditioner evaporator coil ine chinangwa chekutonhodza mhepo inopfuura nayo.Iwo machubhu akacheneswa anogadzirwa kuKainon Boilers, anoshandisa yakakwira giredhi kabhoni simbi, Stainless simbi, mhangura, ndarira, uye aluminium.Yedu yakacheneswa machubhu exchangers akagadzirwa kuti asangane neiyo chaiyo yebasa mamiriro, tembiricha uye kudzvanywa kwemvura.
