01 Isingeniso Esipholile
Isipholisa, njengoba negama lisho, siwuketshezi olusetshenziswa ukugcina amakhaza, kumele sibe namandla okugcina ukubanda.Kukhona into engokwemvelo epholile kahle, okungamanzi.Kuyaziwa ukuthi amanzi azoqina ebusika lapho izinga lokushisa lingaphansi kuka-0 °C.Eqinisweni, inqubo yokuqandisa ukuthi amanzi awuketshezi aguqulwa abe amanzi aqinile lapho kugcinwe amandla abandayo.Phakathi nale nqubo, izinga lokushisa lengxube yamanzi e-ice lizohlala ku-0 ° C kuze kube yilapho amanzi eshintsha ngokuphelele eqhweni, ngaleso sikhathi ukugcinwa kwamanzi okubandayo kuyaphela.Lapho izinga lokushisa langaphandle leqhwa elakhiwe lingaphezu kuka-0°C, iqhwa lizomunca ukushisa kwemvelo futhi lincibilike libe emanzini.Phakathi nenqubo yokuqedwa, izinga lokushisa lengxube yamanzi eqhwa lihlala li-0 ° C kuze kube yilapho iqhwa lincibilika ngokuphelele emanzini.Ngalesi sikhathi, amandla abandayo agcinwe emanzini akhululiwe.
Enqubweni engenhla yokushintshana phakathi kweqhwa namanzi, izinga lokushisa lengxube yamanzi eqhwa lihlala liku-0 ℃ futhi lizohlala isikhathi esithile.Lokhu kungenxa yokuthi amanzi ayimpahla yokuguqula isigaba ku-0 ℃, ebonakala ngokushintsha kwesigaba.Uketshezi luba luqinile (exothermic) , okuqinile kuba uketshezi (endothermic), futhi izinga lokushisa ngeke lishintshe isikhathi esithile endaweni yokushintsha isigaba ngesikhathi sokushintsha kwesigaba (okungukuthi, lizoqhubeka limunca noma likhulule inani elikhulu. ukushisa phakathi nenkathi ethile yesikhathi).
Ukusetshenziswa okuvame kakhulu kokupholisa kwesigaba sokushintsha empilweni yethu yansuku zonke "ukugcinwa" kwezithelo, imifino nokudla okusha.Lokhu kudla kulula ukuwohloka ngaphansi kwezinga lokushisa eliphezulu.Ukuze sinwebe ubusha , singasebenzisa isibandisi sokushintsha isigaba ukulungisa izinga lokushisa elizungezile ukuze sifinyelele umphumela wokulawula izinga lokushisa nokulondolozwa:
02 Aisicelo kweAmakhaza Ci-oolant
Ezithelo, imifino nokudla okusha okudinga u-0~8 ℃ ukugcinwa okubandayo, amaphakethe eqhwa apholile kufanele aqandiswe ku--7 ℃ okungenani amahora ayi-12 (ukuqinisekisa ukuthi amaphakethe eqhwa aqandisiwe ngokugcwele) ngaphambi kokusatshalaliswa.Ngesikhathi sokusatshalaliswa, amaphakethe eqhwa apholile kanye nokudla kuzofakwa ku-cooler box ndawonye.Ukusetshenziswa kwamaphakethe e-ice kuncike kusayizi webhokisi le-cooler kanye nobude besikhathi sokuvala.Uma ibhokisi lilikhulu futhi uma ubude be-insulation buyinde, kuzosetshenziswa amaphakethe eqhwa.Inqubo yokusebenza ejwayelekile imi kanje:
03 Aisicelo kweI-Frozen Coolant
Ngokudla okusha okuqandisiwe okudinga u-0 ℃ ukugcinwa okubandayo, amaphakethe eqhwa afakwe esiqandisini kufanele aqandiswe ku--18 ℃ okungenani amahora ayi-12 (ukuqinisekisa ukuthi amaphakethe eqhwa afakwe esiqandisini ngokugcwele) ngaphambi kokusatshalaliswa.Ngesikhathi sokusatshalaliswa, amaphakethe eqhwa afakwe esiqandisini kanye nokudla kufanele kufakwe ku-incubator ndawonye.Uma i-cooler box iba nkulu futhi uma ubude be-insulation buyisikhathi eside, kuzosetshenziswa amaphakethe eqhwa.Inqubo yokusebenza ejwayelekile imi kanje:
04 Ukwakheka Okupholisayo Neziphakamiso Zokusetshenziswa
Ngokuthuthuka komphakathi, izinga lempilo labantu liya ngokuya likhuphuka, futhi imvamisa yokuthenga nge-inthanethi esikhathini se-inthanethi nayo iyanda.Ukudla okuningi okusha kanye neqhwa kulula ukuwohloka kwezokuthutha ngaphandle "kokulawula izinga lokushisa nokulondolozwa".Ukusetshenziswa kwe- "phase change coolant" sekube yisinqumo esingcono kakhulu.Ngemva kokuba ukudla okusha kanye neqhwa sekulawuleke kahle izinga lokushisa futhi kwagcinwa kukusha, izinga lokuphila labantu liye laba ngcono kakhulu.
Ngokusetshenziswa njalo kwe-0 ℃ namaphakethe eqhwa aqandisiwe, ingabe isibandisi esivuzayo esisuka ekuqhumeni kwamaphakethe eqhwa ngesikhathi sokuthutha singabeka engcupheni ukuphepha kokudla?Ingabe izobangela ukulimala emzimbeni womuntu uma idliwe ngaphandle kokwazi?Ukuphendula lezi zinkinga, senza imiyalo elandelayo yamaphakethe eqhwa:
