Grai kaja ai nbung galai shai ai jak langai hku nna, spiral nbung galai shai ai jak a laklai ai spiral hkrang gaw nbung galai shai ai atsam hpe grau kaja hkra galaw ya ai sha n-ga, lwi ai atsam ni hpe mung grai shadut ya lu ai (ga shadawn, hka lwi ai atsam, n-gun yawm ai, mass galai shai ai akyang lailen ni zawn re ai ni). Shi a lwi ai atsam hpe hkaja ai gaw, hpaga lam hta jai lang ai hta kaja dik htum hkrang shapraw na matu ahkyak nga ai.
Hka lwi ai lam hte seng nna, spiral heat exchanger a spiral channel gaw hka hpe spiral lam hku hkan sa na matu shadut ya ai majaw, n-gun ja ai secondary lwi ai lam hte turbulence byin pru wa ai. Ndai lwi ai ladat gaw hka kayau ai lam hpe jat ya nna, lamu ga jarit n-gun hpe shayawm ya ai, dai hku nna katsi ai hpe htawt sit ai coefficients ni hpe grau kaja hkra galaw ya ai. Htunghking shell-and-tube n-gun galai ai jak ni hte shingdaw yu yang, spiral structure gaw lwi ai hpe ninghkap ai lam hpe kaja wa shayawm ya lu ai, grau nna -viscosity kaba ai ntsin ni hpe hparan ai shaloi. Dai hta n-ga, spiral channel matut manoi nga ai gaw, si ai shara ni hpe shayawm ya nna, n san seng ai lam hpe shayawm ya ai, jak rung a prat hpe galu shangun ai.
Pressure hkrat sum ai lam gaw hka lwi ai atsam hta ahkyak ai masa langai rai nga ai. Spiral heat exchanger a pressure hkrat sum ai lam gaw madung hku nna spiral diameter, channel galu kaba ai lam, hka lwi ai lam ni a majaw byin pru wa ai. Jat wa ai spiral lam gaw, dingyang nga ai hka htung hta grau galu ai hka lwi ai lam hpe byin shangun ai raitim, n-gun jat wa ai secondary flow a majaw, yawng hkra a n-gun yawm ai lam gaw myit mada ai hta grau yawm nga ai. Hpaji sawk sagawn ai lam ni hta, nbung laru htawt sit ai masa langai sha hta, spiral nbung laru galai shai ai jak ni gaw, shell-and-tube nbung laru galai shai ai jak ni hta grau nna n-gun yawm ai lam hpe madun dan ai majaw, pumping n-gun lang ai lam hpe shayawm ya lu nna, system sut masa hpe grau kaja hkra galaw ya lu ai.
Mass htawt sit ai lam hte seng nna, spiral structure gaw hka htung ni a lapran hta maren mara kayau kaya byin wa hkra galaw ya ai majaw, gas-hka htung (sh) hka htung-hka htung mass htawt sit ai lam ni a matu grau nna htuk manu ai. Ga shadawn, tsi mawan galaw shapraw ai hta, spiral heat exchanger ni hpe lang nna, n-gun rawng ai arung arai ni a lapran mass transfer hpe jat ya lu ai. Shanhte a optimized logistics properties ni a majaw, shanhte hpe sau, tsi mawan, malu masha galaw shapraw ai zawn re ai hpaga lam ni hta grai law hkra jai lang wa sai.
Hpang jahtum tsun ga nga yang, spiral heat exchanger ni a logistics properties ni gaw, shanhte hpe n-gun n law ai, n-gun n law ai, grai kaja ai mass transfer performance ni hta ahkyak ai akyu ni jaw ya ai majaw, dai ni na aten na industrial heat exchange hpaji masa hta ahkyak ai rawt jat lam lam langai byin wa ai.
