3. Obere nha, ịdị arọ dị arọ na nhazi kọmpat. The thermal conductivity nke fluoroplastic dị ala, naanị 0.19W / m.℃, nke bụ 1/250 nke nkịtị carbon ígwè. Iji belata nguzogide okpomọkụ nke mgbidi tube ma mee ka ọnụọgụ ọkụ na-ebufe ọkụ zuru oke, a na-ejikarị tubes ndị nwere mgbidi dị mkpa. Iji hụ na ike nke tubes nwere mgbidi dị mkpa, a ga-eji tubes dị ntakịrị mee ihe. N'ihi iji ọnụ ọgụgụ buru ibu nke obere tubes dayameta, ebe a na-ebufe okpomọkụ kwa otu olu dị ukwuu. Ihe Nlereanya: E jiri ya tụnyere ịdị arọ na olu nke otu 10-square-mita PTFE okpomọkụ okpomọkụ na metal ma ọ bụ na-abụghị metal graphite okpomọkụ Exchanger, PTFE okpomọkụ Exchanger bụ nanị banyere 1/2 nke ọzọ abụọ. Enwere ike ịhụ na ụdị okpomọkụ a nwere ike ịdị ntakịrị na nha dị arọ, si otú ahụ chekwaa njem, ntinye na ụgwọ ọrụ.
