NF Group 10KW 800V High Voltage Thin-film Coolant Heater HVCH EV Coolant Heater

Chidziyo chekupisa chine firimu rakatetepa chine hunyanzvi hwepamusorohita inotonhorera ine voltage yepamusoroYakagadzirwa sechitofu chemotokari dzemagetsi. Yakagadzirwa ichishandisa physical vapor deposition nedzimwe nzira dzinobva ku semiconductor, inoisa zvinhu zvakawanda zvinoshanda pa substrate yakatetepa zvakanyanya, ichigadzira chinhu chinodziya chinodzivirira kupisa chinoshanda zvakanaka chine hunhu hwakanaka uye kugara kwenguva refu. Inoita kuti kupisa kupedzisire nekukurumidza, ichisvika pakupisa kwakananga mukati memasekonzi.

Zvichienzaniswa nePTC heaters dzemazuva ano, tekinoroji yethin-film inopa hunhu hwakanaka. PTC heaters dzinorasikirwa nesimba sezvo resistance inowedzera nekupisa, zvichiita kuti simba ridzikire uye simba risingashandiswi. Kusiyana neizvi, thin-film heaters dzinochengetedza kushanda kwakasimba kwe96–97% munzvimbo dzakasiyana dzekushanda. Dzinogonesa kutonga kwesimba kwakaringana kuburikidza nePWM uye hadzigadzire inrush current pakutanga, dzichidzivirira midziyo yemagetsi inonzwisisika. Chinhu chadzo chinonyanya kukosha ndechekuti dzinoshanda zvakanaka nemapuratifomu ane voltage yakawanda: dzinotsigira 400V kusvika 1000V, dzinopfuura muganho wemayuniti ePTC, ayo akakosha kune 800V architectures. Uyezve, hadzina lead uye hadzina rare-earth, uye mutengo wadzo ikozvino wakaenzana nePTC. Izvi zvinoita kuti dzishande zvakanaka pasi pemitoro yakasiyana-siyana.

Mukushandiswa kwayo, mudziyo uyu unoshanda sehita inotonhodza bhatiri, kuchengetedza bhatiri pa 20–45°C kuchengetedza kureba uye hupenyu hwebhatiri.heater yemagetsi yemagetsi, inodziya imba nekukurumidza uye inodzima mahwindo kana kuchitonhora. Inoshandawo sechitofu chekupisa chinotanga kutonhora. Izvihita yemvura ine voltage yakakwirasaka chinhu chakakosha pakutarisira kupisa kwemotokari dzemagetsi.

Semubatsiri anovimbwa naye, Hebei Nanfeng Automobile Equipment (Group) Co., Ltd, yakavambwa muna 1993, ikambani ine mafekitori matanhatu. Isu tiri vatengesi vanotungamira vezvinhu zvitsva zvemotokari dzemagetsi muChina uye isu tiri vatengesi vakasarudzwa vemotokari dzemauto eChina. Chigadzirwa chedu chikuru chinosanganisira hita inotonhorera ine voltage yakawanda,pombi yemvura yemagetsi, BTMS, compressor yemhepo yemagetsi, EPS, EHPS, compressor yemhepo inotonhodza yemagetsi, vharuvhu yenzira nhatu, hita yekupaka, hita yekupaka, uye plate heat exchanger. Munguva pfupi yapfuura, Nanfeng Group yakatanga series yehita ye10 kW thin-film. Tinogamuchira nemufaro mibvunzo kubva kune vatengi vatsva nevaripo.
