Ko te uho oHe whakamahana PTC EvE whakawhirinaki ana ki ngā āhuatanga rauemi o te whakamahana pāmahana pai PTC, me te pūnaha tuku hiko ngaohiko teitei me te ara iahiko whakahaere wera o ngā waka hiko hei whakatutuki i te whakamahana. Ko te tikanga, ka hurihia te pūngao hiko hei pūngao wera, kātahi ka tukuna ki te kāpata, ki te pākahiko rānei mā te reo (hau/hau). He āhuatanga whakawhāiti-ake, he āhuatanga whakahaere-ake anō hoki puta noa i te tukanga, me te kore e hiahiatia he taputapu whakahaere pāmahana matatini anō, ka waiho hei otinga whakamahana whai hua, haumaru hoki mō ngā waka hiko hou.
E rua ngā paparanga o te tukanga whānui: ngā mātāpono rauemi matua me te rerema mahi mō te whakamahinga motuka. Tērā pea ka rerekē te tuarua i runga i te horopaki tono (whakamahana kāpata/whakamahana pākahiko). Ko te nuinga mō te whakamahinga motuka kongā whakamahana PTC wai whakamatao(te whakawhiti wera o te hauhautanga), ko te iti o te whakamahana kāpata e whakamahi ana i ngā whakamahana PTC kua whakamahanahia e te hau (te whakawhiti wera hau tika). Ko ngā whakamārama e whai ake nei:
1, Matua taketake: Te mātāpono whakamahana me te whakawhāiti pāmahana whaiaro o te PTC thermistor
Ko te wāhanga whakamahana matua oWhakamahana PTChe pepa uku PTC (he uku semiconductor e hangai ana ki te barium titanate kua pania ki ngā huānga whenua onge), koinei te pūtake o ōna āhuatanga katoa:
Te whakamahana: Ka hangaia e ngā maramara uku PTC ngā ara kawe hiko me ngā kongakonga kawe hiko o roto i te ngaohiko kua whakatauria (ngaohiko teitei DC mō te whakamahinga motuka, pērā i te 300V+/400V+), ka whakaputa i te wera Joule ina pā te iahiko, ka tutuki te huringa tika o te pūngao hiko ki te pūngao wera me te pai o te whakamahana (tata ki te 100%, kāore he ngaronga huringa pūngao);
Te pāmahana whakawhāiti-ake (āhuatanga matua): Ina kore te pāmahana o ngā maramara uku PTC e eke ki te pāmahana Curie (te pāmahana nui o ngā rauemi, ko te tikanga 120-180 ℃ mō te whakamahinga motuka), he iti rawa te uara ātete, ā, ka puta tonu te wera nui me te wera nui, ka tere te piki o te pāmahana;
Kia hipa ake te pāmahana i te pāmahana Curie, ka tere te pakaru o te ara kawe hiko o roto, ā, ka piki haere te ātete (tae atu ki te 10 ³~10 ⁶ ngā wā o te ātete i te pāmahana rūma). E ai ki te ture a Ohm (P=U ²/R), i raro i te ngaohiko pumau, ka tino heke te mana whakamahana, ā, ka iti iho te tere whakamahana i te tere marara wera. Ka pumau te pāmahana tata ki te pāmahana Curie, ā, e kore e piki tonu, ka karo i te wera maroke me te wera nui mai i te pakiaka;
Te whakaora-ā-ake: Ina heke te pāmahana i raro i te pāmahana Curie nā te mararatanga o te wera (pēnei i te rere o te hau whakamatao/hau), ka tere te whakaora o te ātete ki te āhua ātete iti, ka tīmata anō te whakamahana mana-tiketike, ā, ka tutuki te whakahaere-ā-ake hihiri o te mana pāmahana.
2, Otinga matua mō te whakamahinga motuka: Te tukanga mahi o te whakamahana PTC wai whakamatao (ao whānui mō te whakamahana kāpini/pūhiko)
Neke atu i te 90% o ngā waka hiko e whakamahi ana i ngā whakamahana PTC wai-whakamatao teitei (he hanganga kiato, he whakawhiti wera ōrite, he pai mō te ara iahiko hau mahana o te kāpini me te ara iahiko whakahaere pāmahana pākahiko), kua whakauruhia ki roto i te ara iahiko tohanga whakamatao o ngā waka hiko hou. Ka tutuki noa te whakamahana o te kāpini me te pākahiko mā te whakawhiti i waenga i ngā ara iahiko rerekē o te pūnaha whakamahana PTC kotahi. He rite tonu te tukanga matua, e whā ngā taahiraa:
Te tīmatanga o te pūhiko hiko: Ka tukuna e te VCU (Wāhanga Whakahaere Waka) te tohu tīmatanga ki te whakamahana PTC i runga i te whakahau hauhautanga o te kāpini/tohu pūoko pāmahana pākahiko (mēnā me whakamahana te pākahiko i raro i te 5 ℃), ā, i te wā kotahi ka hono i te ara iahiko pūhiko hiko o te pākahiko ngaohiko teitei o te waka. Ka whakaurua te mana DC ngaohiko teitei ki te huānga whakamahana PTC;
Te hurihanga hiko ki te wera: Ka tere te whakaputa wera o ngā pereti uku PTC i raro i te iahiko ngaohiko teitei, ka eke ki te pāmahana mahi i roto i ngā hēkona, ā, ka whakawhitia te wera ki te rūma whakamarara wera/ngoi whakawhiti wera o te whakamahana PTC;
Whakawhiti Wera Whakamatao: Mā te papu wai hiko o te pūnaha whakahaere wera o te waka ka panaia te whakamatao kia rere i roto i ngā ngongo whakawhiti wera o te whakamahana PTC. I muri i te mimiti i te wera mai i te wāhanga whakamahana PTC, ka huri te whakamatao hei whakamatao pāmahana teitei (ko te tikanga he 40-60 ℃, ka whakarerekētia kia rite ki te hiahia);
Te whakawhiti wera
Te whakamahana o te kāpini: Ka rere te wai whakamatao pāmahana teitei ki roto i te pūtake hau mahana i roto i te motuka, ā, ka panaia e te hau whakamatao o te waka te hau matao mā roto i te pūtake hau mahana. Ka mimiti te hau matao i te wera o te wai whakamatao ka huri hei hau wera, ka tukuna ki roto i te motuka mā te putanga hau hei whakamahana i te kāpini;
Te whakamahana pākahiko: Ka rere tika te whakamatao pāmahana teitei ki roto i te ara iahiko whakawhiti wera/pereti wai-whakamatao o te kete pākahiko hiko, ā, ka whakamahana ōrite i te waeine pākahiko mā te kawe wera, ka whakapiki i te pāmahana pākahiko ki te awhe utu me te tuku e tika ana (te nuinga o te 10-35 ℃), ka whakaoti rapanga o te whakahekenga manawanui pāmahana iti me te iti o te utu me te tuku.
Tāpiri: Kia oti te whakawhiti wera o te whakamatao, ka heke te pāmahana, kātahi ka rere anō ki te whakamahana PTC mā te paipa hei mimiti anō i te wera, ka hanga he huringa kati me te whakamahana tonu; Ina tae te kāpata/pūhiko ki te pāmahana e hiahiatia ana, ka tapahia e te VCU te pūtake hiko ngaohiko teitei PTC ka mutu te whakamahana.
3, Otinga iti: Rerenga mahi o te whakamahana PTC hau (e whakamahia ana mō te whakamahana wāhanga o te kāpata anake)
Ko te whakamahana o roto o ētahi waka hiko iti me ngā tauira iti-mutunga ka whakamahia he whakamahana PTC hau-whakamatao (karekau he whakawhiti wera hauhautanga, ka whakamahana tika i te hau), me te hanganga māmā ake me te tukanga matua o:
Ka whakaputa tika te huānga whakamahana uku PTC i te pūngao wera;
Ka pupuhi te hau makariri i te hau ki runga i te mata o te wāhanga whakamahana PTC, ā, ka whakawhiti tika te hau makariri i te wera ki te pereti uku PTC pāmahana teitei, ka huri hei hau wera;
Ka tukuna tika te hau wera ki roto i te kāpata mā te putanga hau hei whakatutuki i te whakamahana tere.
Ngā Huakore: Kāore i te ōrite te whakawhiti wera, he ngāwari ki te hau wera ā-rohe, ā, ka pā tika te huānga whakamahana PTC ki te hau, ka nui ake te ātete ki te puehu me te wai. Nō reira, ka whakamahia anake mō ngā tauira motuka iti utu iti, ā, ka whakamahia te whakamatao wai mō ngā waka hiko hou waenga ki te teitei.
