Chitoliro chokulirapo ndi mtundu wa chitoliro chokhala ndi poyambira pambuyo pakugudubuza.Wamba: chozungulira grooved chitoliro, chowulungika grooved chitoliro, etc. ndi dzina grooved chitoliro chifukwa poyambira zoonekeratu zikhoza kuoneka mu gawo la chitoliro.Chitoliro chamtunduwu chimatha kupangitsa kuti madzimadzi aziyenda pakhoma la zida za chipwirikitizi, kupanga madera olekanitsa otaya, ndikupanga ma vortices okhala ndi mphamvu ndi makulidwe osiyanasiyana.Ndi ma vortices awa omwe amasintha kayendedwe ka madzimadzi ndikuwonjezera chipwirikiti pafupi ndi khoma, kuti apititse patsogolo filimu yotengera kutentha kwa convective yamadzimadzi ndi khoma.

a.Rolling groove chubu rolling groove chubu ndikugudubuza kopingasa kapena kozungulira kozungulira ndi phula ndi kuya kwake kuchokera kunja kwa chubu chozungulira molingana ndi kapangidwe kake, ndikupanga nthiti yopingasa kapena nthiti yozungulira pakhoma lamkati la chubu. , monga momwe tawonetsera pa Chithunzi 1. Mphepete pa khoma lakunja ndi kutuluka kwa khoma lamkati la chitoliro kungapangitse kutentha kwa madzi kumbali zonse ziwiri za chitoliro panthawi imodzi.Ndi makamaka oyenera kulimbikitsa kutentha kutengerapo wa limodzi gawo madzimadzi mu chitoliro ndi utithandize nthunzi condensation ndi madzi filimu otentha kutentha kutengerapo za madzimadzi kunja kwa chitoliro mu exchanger kutentha.

b.Spiral grooved pipe ili ndi pass single ndi multi pass spiral ndi mitundu ina.Pambuyo pakupanga, pali poyambira yokhala ndi ngodya ina yozungulira kunja kwa chitoliro cha spiral groove, ndipo pali nthiti zofananira m'chitolirocho.Kuzungulira kozungulira sikuyenera kukhala kozama kwambiri.Kuzama kwa poyambira kumakhala kokulirapo, kukana koyenda kumakulirakulira, kozungulira kozungulira, komanso kuchuluka kwa filimu yotengera kutentha kwa chubu chokulirapo.Ngati madzimadzi amatha kuzungulira poyambira, kuchuluka kwa ulusi kumakhala ndi zotsatira zochepa pakutengera kutentha.

c.Mtanda grooved chitoliro aumbike ndi variable mtanda gawo mosalekeza anagubuduza.Kunja kwa chitoliro ndi chopingasa poyambira intersecting chitoliro olamulira pa 90 °, ndipo mkati mwa chitoliro ndi yopingasa nthiti otukukira madzi.Pambuyo pa kutuluka kwamadzimadzi kumadutsa nthiti ya convex mu chitoliro, sikutulutsa madzi ozungulira, koma kumapanga magulu a axial vortex pamodzi ndi gawo lonse, kuti alimbikitse kutentha kwa kutentha.The mtanda ya threaded chubu alinso kulimbikitsa kwambiri filimu otentha kutentha kutengerapo kutengerapo madzimadzi mu chubu, amene akhoza kuonjezera otentha kutentha kutengerapo coefficient ndi 3-8 zina.
