Standard hte chyam dinglik ai ladat ni a lit gaw, galaw shapraw ai ni gaw thermal performance hpe gara hku hkan sa ai lam hpe shabyin ya ai. ASHRAE zawn re ai uhpung ni gaw, data center arung arai ni a matu hkap la mai ai nbung laru hte hka lim ai shara ni hpe tsun dan ai. Automotive madang ni gaw charge rate amyu myu hte grup yin masa ni a npu e battery thermal chyam dinglik ai lam hpe tsun da ai.

Material lata ai lam gaw thermal management system a bungli galaw ai lam hte asak galu ai lam hpe grai hkra machyi shangun ai. Copper gaw grai kaja ai thermal conductivity hpe jaw ya ai raitim, n-gun hte manu hpe jat ya ai. Aluminum gaw manu n law ai hte magri hta 67% n law ai, raitim shi a thermal conductivity gaw magri mang a 60% daram rai nga ai. Synthetic diamond sumla hkrung zawn re ai arung arai nnan ni gaw, grau tsaw ai arawn alai hpe lu la ai raitim, manu jahpu ni gaw, manu jahpu gaw, bungli galaw ai lam hta lahkawng ngu na shara kaw nga ai laksan application ni hpe sha tawn da ai.

Thermal management gaw kaga masa ra kadawn ai lam ni hte grai sawng ai ladat ni hte matut mahkai nga ai. Hka lum na matu nbung hpe pat shingdang ya ai hka lim ai hte nhprang wan n-gun hpe makawp maga ya ai sealed electronics ni hpe shinggrup da ai.
