I. Basic Concepts uye Design Philosophy
The spiral{{0}tube heat exchanger mudziyo wakakwana wekuchinja kupisa unogadzirwa nekumoneredza kupisa{1}}kutamisa machubhu kuita spiral configuration ine pitch uye radius yekumonereka; mvura inopisa neinotonhora inoyerera nemumachubhu nedivi regoko, zvichitevedzana, ichichinjanisa kupisa nemadziro echubhu.
· Yayo musimboti dhizaini uzivi ndeye synergistically kusimudzira kupisa kwese kwese kuchinjisa kuita mukati menzvimbo shoma nekuwedzera panguva imwe chete nzira dzekuyerera, kuwedzera mhirizhonga yemvura, uye kuwedzera kupisa kwenzvimbo density.
Zvichienzaniswa nemaitiro echinyakare-magadzirirwo echubhu, spiral structure inosimudzira zvakanyanya simba rekutamisa kupisa pavhoriyamu yega yega pasina kuwedzera saizi yese yemudziyo, zvichiita kuti ive yakakosha zvakanyanya{1}}kugona, simba-kusevha masisitimu.
II. Nheyo dzeKutamisa Kupisa Dhizaini
Kutamisa kupisa muspiral-tube heat exchanger zvichiri kuenderana nemaitiro ekare ekuitisa kupisa uye convective heat transfer-apo kupisa kunoitwa nemudhuri wechubhu uye kutakurwa nekufambiswa kwemvura inopisa neinotonhora-asi pundutso yayo huru iri mukunatsiridza kufambiswa kwekupisa.
.
·Sezvo mvura ichiyerera nemu spiral chubhu, curvature inokonzera centrifugal forces inoshandura velocity profile, ichigadzira transverse secondary flows (Dean vortices); ichi chinoyerera chimiro chinoramba chichikwenya madziro echubhu, zvichikanganisa thermal boundary layer.
Kuramba kutetepa kwemuganhu wekupisa kunowedzera zvakanyanya kuchinjisa kupisa kwenzvimbo, ukuwo spiral configuration inotambanudza nzira yekuyerera kwemvura, zvichiita kuti tembiricha-musiyano wekutyaira ushandiswe zvizere uye nekudaro kuwedzera kupisa kwese kunoshanda zvakanaka.
III. Flow Intensification Mechanism
The helical structure inoshandura unidirectional axial flow pateni inowanikwa mumapombi akatwasanuka, achikwirisa kutenderera kuchinjika paaxial kuyerera zvichibva zvagadzira yakaoma, -dimensional flow field.
·Kuyerera kwechipiri uku kunonatsiridza kusanganiswa kwemvura, kunosimudzira tembiricha yakafanana pakati pezvinopisa nezvinotonhora, uye kunonatsiridza mashandisirwo enzvimbo inoshanda yekupisa kupisa.
·Kunyangwe nenhamba dzeReynolds dzakadzikira, geometry inounza nyonganyonga{{0}sezvinoita kuti iwedzere, zvichiita kuti inyanyokodzera kune yakakwira-zvinwiwa zveviscosity kana kuti transitional flow regimes.
·Uyezve, kuyerera kwakanyanya kunoderedza mukana wekuiswa kwenzvimbo uye kukanganisa, zvichibva zvawedzera kugadzikana kwekushanda kwenguva refu.
IV. Key Parameters for Structural Design
·Iyo dhayamita yecoil ndiyo parameter yakakosha inokonzera kupisa kutamisa kuita; dhayamita diki inokonzeresa kudzika uye kusimba kwechipiri kuyerera asi zvakare kunowedzera zvakanyanya kudzikira, zvichidikanwa dhizaini yakagadziridzwa inoyera kushanda nesimba uye kushandiswa kwesimba.
Iyo coil pitch inotaridza compactness yemvura inoyerera nzira; diki diki rinowedzera chubhu-kudivi kuyerera nzira paurefu hweyuniti uye inowedzera kupisa kwenzvimbo density, kunyangwe ichikwidzawo kuoma kwekugadzira uye kusaramba kuyerera.
Natus illo curabitur incidi dunt dignissim mollis, atque nesroder posuere semper nemo ea? Maxime, repellat, eleifend iste, eges.
Shell-side structural design yakakosha zvakaenzana; kuve nechokwadi chekugoverwa kwemvura yakafanana kwakakosha kudzivirira kupfupi-kutenderera, nzvimbo dzakafa, kana nzvimbo dzenzvimbo dzakaderera, sezvo izvi zvingaderedza zvakanyanya kunaka kwekutamisa kupisa.
V. Nheyo yeSynergistic Thermal uye Aerodynamic Design
·Mukugadzirwa kwehelical-coil heat exchanger, hukama hwakabatana pakati pekushanda kwemafuta nekuyerera kunofanirwa kutariswa, sezvo kuwedzera kwekupisa kunowanzoperekedzwa nekudonha kwakawedzera.
·Magadzirirwo acho anowanzo tarisa huwandu hwese hwekutamisa kupisa (U-value) uku uchimanikidza kudonhedza kunotenderwa kuti usvike pakunyatsoshanda kwesimba.
·Nekugadzirisa zvimiro zvakaita seredhiyo yecoil, pitch, dhayamita yechubhu, uye kuyerera kwevelocity kugovera, magadzirirwo akakwana anogona kuwanikwa kune akasiyana ekushanda mamiriro; semuenzaniso,-kupisa-kusiyana kwemamiriro ezvinhu kunofadza madhizaini ane mhirizhonga yakanyanya, nepo kushomeka-simba{3}}mashandisirwo emagetsi anofarira zvivakwa zvine kuderera kwekuderera.
·Injiniya dhizaini inowanzo shandisa segmental kuverenga kana manhamba ekuenzanisa kuita ongororo yemunharaunda yeakasiyana matunhu ekuyerera, nekudaro achisimbisa dhizaini.
VI. Inoshanda Mamiriro Ekushanda uye Injiniya Zvakanakira
Spiral-tube heat exchanger inonyanya kufanira-kunyatsoenderana ne-viscosity fluids (semafuta, resin, nesyrup) uye media ine zvimedu zvakaomarara kana isingatani kusvibiswa, sezvo kutenderera kwakanyanya kunoderedza njodzi yekuisa.

Iwo anoshandiswa zvakanyanya mumakemikari, peturu, kugadzira chikafu, mishonga, uye simba rekudzoreredza masisitimu, zvichiita kuti zvive zvakanyanya kunaka kune zvinoramba zvichigadzira zvivakwa.
Pamusoro pezvo, yavo yakaomesesa dhizaini uye kuramba kwakasimba kwekushushikana kwekupisa kunovimbisa kuvimbika kwakanyanya pasi pemamiriro anosanganisira kusiyana kukuru kwekushisa kana kuchovha bhasikoro.
