Izvo zvinopisa zvesimbi furo zvinosanganisira kunyungudika, chaiyo kupisa, kupisa kwekuwedzera kweiyo coefficient, thermal conductivity, thermal diffusivity, thermal radiation uye thermal shock resistance, mamwe acho akafanana nematrix zvinhu, nepo mamwe ane hukama neporosity, Pore. mhando uye pore saizi zvine hukama.
Zvishandiso zvine good thermal conductivity zvinowanzotora kupisa nekukurumidza uye kubvisa kupisa nekukurumidza. Kana mamwe masisitimu achida huwandu hukuru hwekupisa kana kupisa kupisa panguva yekushandiswa, zvinhu zvine yakanaka thermal conductivity zvinosarudzwa. Zvinoenderana neiyo yekupisa conductivity chinzvimbo chesimbi dzakachena, sirivheri, mhangura, aluminium, tungsten, magnesium uye zvimwe zvinhu, nepo kupisa kwemafuta alloys kunowanzo kunyanyisa. Zvinogona kuonekwa kuti thermal conductivity yemhangura inopisa sinks ndiyo yakanakisisa pakati pematare emabhizimisi.

Saka nei masingi ekupisa achinyanya kugadzirwa nealuminium pachinzvimbo chemhangura?
Ichokwadi zvakare kuti mhangura inobata kupisa zvakanyanya nekuti ine yakanyanya kupisa conductivity kupfuura aluminium. Asi simba rekupisa kupisa kweradiator rinotsamira kwete chete pakupisa kwekupisa kwezvinhu, asiwo panzvimbo yekupisa kupisa, chimiro che radiator, uye mamiriro ekuyerera kwemhepo.
Hazvina mhosva kuti huwandu hwekupisa hwemhangura hudiki sei, huwandu hwekupisa hwemhangura hunofanirwa kunge hwakaderera, tembiricha yayo inokwira nekukurumidza, uye zviri nyore kubvisa kupisa. Nekudaro, kuwanda kwemhangura ndeye 3.3 nguva yealuminium. Radiator chigadzirwa chehukuru uye haigone kuwedzerwa nekusingaperi. Ipapo huremu hwemhangura hwakakura kune imwechete volume.
Pasi pezvinhu zvakawanda, mari yemhangura yemhangura inowanzopfuura 400% inodhura kupfuura iyo yearuminiyamu radiators, asi maererano nemutengo, misika haigoni kubvuma mhangura yemhangura iyo inokwana 4 mutengo.
Saka pane chero chinhu chinogona kuve nekupisa kwemhangura, asi huwandu uye huremu hunofananidzwa nealuminium?
Foamed mhangura inogona kunge iri chinhu chitsva chakakodzera kutariswa, icho chine akawanda akabatana uye akadimburwa pores akagoverwa zvakaenzana mumhangura matrix. Foamed copper ine yakanaka magetsi conductivity uye ductility, uye ine yakaderera mutengo wekugadzirira uye yakanaka magetsi conductivity.
