Active hte Passive Cooling lapran na lata la ai

Active cooling gaw shi a jat bang da ai yak hkak ai lam hpe tara shang shatai ya ai kun ngu ai hpe lam law law gaw dawdan ya ai:

Passive cooling hpe lata u:

Katsi ai n-gun gaw 50-100W npu kaw naw nga ai.

Ambient nbung katsi ai lam gaw, n-gun kaba dik htum ratings ni a lawu e nga ai

Space constraint ni gaw loi mi sha re

Kam hpa mai ai lam hte gram lajang ai lam-law ai bungli galaw ai lam gaw grau nna ahkyak ai

Budget gaw grai pat shingdang da ai

Active cooling hpe lata u:

Katsi ai n-gun gaw 100W jan ai (sh) thermal density grai tsaw ai hpe shabyin ya ai

Ambient nbung katsi ai ladat ni (sh) daw ni hpe lai di ai

Temperature gaw hkam sharang ai lam ni hta naw nga ra ai

Space efficiency gaw asan sha re ai hta grau ahkyak ai

Component prat hte bungli galaw ai lam gaw, gumhpraw bang ai lam hpe tara shang shatai ya ai

100Ah a n-gun (sh) lawan ai-charging masa hta jan ai lithium iron phosphate battery ni a matu, active cooling gaw, lata la mai ai lam hta grau nna, madung hku nna hkan sa ra ai lam byin wa ai.

Ga San ni hpe ayan san ai

Active hte passive cooling lapran na madung shai hkat ai lam gaw hpa rai ta?

Active cooling gaw, nbung hpe shamu shamawt na matu, fans (sh) pump zawn re ai powered device ni hpe lang ai, passive cooling gaw shingra tara katsi ai lam hpe n-gun jaw ai, hpawng de ai, nhtoi htoi tu ai hku nna kam hpa ai. Active system ni gaw grup yin npu na nbung katsi ai lam hpe makawp maga ya lu nna, grau law ai katsi ai n-gun ni hpe hkam sharang lu ai, raitim n-gun hte gram lajang ra ai.

Active cooling gaw kade daram n-gun hpe jai lang ai kun?

N-gun lang ai lam gaw application hte n bung ai. Fan- kaw nga ai system ni gaw 100W hta 5-10W hpe shaw kau ai. Liquid cooling pump ni gaw 100W hta 8-12W hpe shaw kau ai. Refrigeration system ni gaw 100W langai hta 20-40W hpe jai lang nna, nbung katsi ai lam hte n-gun atsam hta hkan nna, n-gun n-gun hpe jai lang ai.

Active cooling gaw battery a asak hpe galu shangun lu ai kun?

Rai sai, grai ahkyak ai. 20-35℃range kata na lithium iron phosphate battery ni hpe gram lajang ai gaw, nbung katsi ai shara ni hta bungli galaw ai hte shingdaw yang, lahkawng lang (sh) masum lang jat ai prat hpe lu la mai ai. Hpaji sawk sagawn ai lam ni hta, 3,000+ mawdaw ni hte 1,000-1,500 shingjawng ai lam ni hpe n-gun n rawng ai sha, shamu shamawt ai thermal management ni lawm ai battery ni hpe madun da ai.

Liquid cooling gaw nbung katsi ai hta grau kaja ai kun?

Liquid cooling gaw nbung katsi ai hta 5-10x grau tsaw ai nbung hpe hkam sharang lu nna, nbung katsi ai lam hpe grau kaja hkra galaw lu ai, raitim 3-5x grau manu dan nna, yak hkak ai lam ni hpe jat ya lu ai. 200W npu na katsi ai hpe hkam la na matu, nbung katsi ai gaw ram sai. 500W jan hta, hka lum ai lam gaw tatut galaw sa wa na matu ra kadawn wa ai.

Active cooling gaw thermal hparan ai lam hpe shadawn sharam ai lam kaw nna galaw lu ai hpaji masa de galai shai shangun ai. Katsi ai hpe htawt sit ai ladat ni hpe shadut na matu, n-gun n law ai atsam hpe jai lang ai hku nna, ndai ladat ni gaw, grau tsaw ai bungli galaw ai madang ni hta, yak hkak ai makau grup yin ni hta, galu kaba wa ai asak hkrung lam ni a matu, daw ni hpe bungli galaw lu shangun ai. Electronics, battery, hte computing arung arai ni hta nbung n-gun ni matut nna rawt jat wa ai hte maren, active cooling gaw ra kadawn ai lam ni hpe jat wa shangun ai kaw nna, npawt nhpang ra kadawn ai lam a npawt nhpang ra kadawn ai lam kaw nna, nbung katsi ai lam hpe hkang zing ai lam gaw shim lum lam, bungli galaw ai lam, sut masa lam ni hpe hkrak hkra dawdan ya ai lithium iron iron phosphate battery ni hta grau nna ra kadawn ai lam ni de galai shai wa ai.
