Tsanangudzo Yakadzama yeHeat Exchanger Working Principles (ine Diagrams)

Chinhu chakakosha chemuchina wekupisa ndechekuchinja kupisa kubva-kumvura yetembiricha kuenda kune yakaderera-mvura yetembiricha{2}}kazhinji pasina kusangana pakati pezviviri izvi{3}}nekushandisa conduction yekupisa uye convection.
 Mvura yakakwira-inoburitsa kupisa, iyo inofambiswa nemumadziro ekuchinja kupisa.
 Kupisa kunoitwa kuburikidza nemudhuri wesimbi (kana kupisa svikiro).
 Mvura yakadzikira-inomwisa kupisa, zvichikonzera kukwira kana kuderera kwekushisa.
 Hurongwa hwese hunotevedza mutemo wechipiri we thermodynamics, umo kupisa kunoyerera kwega kubva patembiricha yepamusoro kuenda kune yakaderera tembiricha.

Zvichienderana negwara rekuyerera kwemvura, kune matatu ekutanga ekuyerera mapatani ekuchinjana kupisa:
 Co{{0}kuyerera kwezvino (parallel flow): Mvura mbiri idzi dzinoyerera dzichienda kwakananga, uye musiyano wetembiricha unodzikira zvishoma nezvishoma.
 Counter-current flow (pakaunda-kuyerera): Mvura mbiri idzi dzinoyerera dzichienda kwakapesana, zvichipa humbozha hwepamusoro-soro.
 Muchinjika-kuyerera: Mvura mbiri idzi dzinoyerera dzichienda kune imwe neimwe; iyi gadziriso yakabatana uye inoshandiswa zvakanyanya.
 Pakati peizvi, kaunda-kurongeka kwazvino kunonyanya kushandiswa muzvishandiso zvemaindasitiri panodiwa hunyanzvi hwepamusoro.

Maitiro ekutamisa kupisa anogona kazhinji kutsanangurwa uchishandisa yakakosha equation yekutamisa kupisa.

Basic heat transfer equation:
Q=U × A × ΔTlm

Kupi:

Mubvunzo: Mwero wekutamisa kupisa (W)
U: Yese yekufambisa kupisa coefficient (W/m²·K)
A: Nzvimbo yekuendesa kupisa (m²)
ΔTlm: Logarithmic zvinoreva kusiyana kwekushisa
Equation manotsi:
Kuwedzera U kana A kunogona kuwedzera zvakanyanya kupisa kwekutamisa huwandu.
Musiyano mukuru wetembiricha unounza simba rakasimba rekutyaira rekuchinjisa kupisa.
