Yadda za a inganta yanayin canjin zafi na raka'a masu musayar zafi?

Ka'idar aiki na mai musanya zafi: Matsakaicin ruwa yana gudana ta cikin ɓangarorin ɓangarorin da ke cikin na'urar musayar zafi a ƙanƙara mai ƙanƙanta, yana haifar da kwararar ruwa, ta yadda za a sami madaidaicin madaidaicin canjin zafi. Za mu iya ƙarasa da cewa ingancin canja wurin zafi yana da alaƙa da alaƙa da siffa da tsari na faranti na ƙwanƙwasa a cikin mai musayar zafi da yanayin kwararar ruwa. Wadanne hanyoyi na musamman za a iya amfani da su don inganta yanayin canjin zafi na mai musayar zafi?

Farantin shine ainihin canjin zafi na farantinmai zafi. Its thermal conductivity and flow channel design kai tsaye ƙayyade ainihin ƙarfin canja wurin zafi kuma dole ne a inganta shi daga tushen farko.

1.Zaɓi kayan da high thermal conductivity a matsayin faranti

Za mu iya zabar 304 bakin karfe, 316L bakin karfe, jan karfe gami da titanium gami a matsayin faranti. Bakin karfe yana da kyakkyawan yanayin zafi da kuma farashi mai ma'ana. Yana da ƙarfi mai ƙarfi, kyakkyawan aikin hatimi, kuma ba a sauƙaƙe oxidized a cikin yanayi mara kyau.

2.Matching m farantin corrugated tsarin

Zane-zanen ɓangarorin farantin yana ƙayyade sifar tashar kwarara kuma kai tsaye yana rinjayar tsananin ruɗar ruwa (mafi ƙarfi tashin hankali, mafi ƙarancin layin iyaka kuma mafi girman madaidaicin canja wurin zafi). Ya kamata a zaɓi nau'in corrugation bisa ga ɗankowar ruwa da buƙatun canja wurin zafi:

3.Reasonable zane na farantin yawa da kuma kwarara tashar hade

Adadin faranti yana ƙayyadad da jimlar wurin canja wurin zafi (A), kuma haɗin tashar tashoshi (guda ɗaya{0}wuce/multi-wucewa) yana shafar ƙimar ruwa. Wajibi ne a daidaita shi daidai da "Load Canja wurin zafi": Lissafin adadin faranti: Dangane da dabarar Q{3}}K × A × ΔTₘ (Q shine nauyin musayar zafi, ΔTₘ shine bambancin zafin jiki na logarithmic), bayan ƙayyade ƙimar K da ΔTₘ, sake ƙididdige mafi ƙarancin wurin canja wurin zafi. Sannan, dangane da ingantaccen yanki na faranti ɗaya (misali, yankin farantin da aka saba amfani da shi shine 0.1{11}}0.5㎡), ƙididdige adadin faranti. Ana ba da shawarar yin tanadin gefe 10% -15% don jure jure juzu'in nauyi na ɗan gajeren lokaci.

Haɓaka haɗin tashar tashoshi mai gudana: Ƙara ko rage adadin hanyoyin kwarara don haɓaka saurin gudu zuwa kewayon tashin hankali (An ba da shawarar Re> 300 a cikin hanyar kwararar farantin). Idan saurin gudu ya yi ƙasa da ƙasa (misali, Re=150 a cikin hanyar guda ɗaya, kwararar laminar), canza zuwa "hanyar ruwa guda biyu- (ruwa yana gudana baya da gaba a cikin farantin, yana ninka hanyar da saurin gudu, kuma yana ƙaruwa Re zuwa 300, don haka shigar da kwararar ruwa).

4.Rage kauri daga cikin faranti a cikin naúrar musayar zafi

Thermal watsin yana da matukar tasiri da kauri daga cikin farantin kanta. Gwaje-gwajen bincike sun nuna cewa a cikin na'urar musayar zafi mai ma'ana, kowane raguwar 0.1mm a cikin kauri na farantin zai iya haɓaka tsarin canja wurin zafi gaba ɗaya ta 600W, yayin da a cikin na'urar asymmetrical, yana iya ƙaruwa da 500W. Sabili da haka, a ƙarƙashin yanayin saduwa da buƙatun aikin injiniya na mai musayar zafi, ƙananan kauri na farantin an tsara shi, mafi girma na thermal conductivity.

5.Siffar sashin ƙwanƙwasa

Ko da yake rarraba damuwa a lokacin matsi yana da ɗanɗano iri ɗaya idan ɓangaren giciye - ɗin ya kasance mai lamba uku, ƙimar canjin zafi na farantin herringbone, wanda ke da wahalar sarrafawa, ya fi girma. Bugu da ƙari, mafi girman kusurwar ƙirar ƙira, mafi girman saurin gudu na matsakaici a cikin tashar ruwa tsakanin rassan farantin karfe, don haka ƙimar canja wurin zafi zai fi girma.

6.Tsaftace ma'auni akan faranti a cikin lokaci

Lokacin da ma'auni a kan farantin ya fi 1mm, za a rage yawan tasirin zafi na kayan aiki da 10%. Don haka, ya kamata a ƙara kayan aikin tacewa a mashigar kuma a tsaftace mai zafi akai-akai. Ta wannan hanyar kawai za'a iya rage kauri na sikelin akan farantin kuma a daidaita ingancin musayar zafi a matakin matakin.
