2. Kayan Canjin Lokaci (PCM) Sanyaya: “Tafkin Tafsiri” don Buffer Heat

① Ka'idar Fasaha:

Yana amfani da kayan canjin lokaci (PCMs) kamar paraffin kakin zuma ko gami na ƙarfe, waɗanda ke ɗaukar ɗimbin zafi na latent yayin jujjuyawar ruwa mai ƙarfi, ta haka lokaci-lokaci yana ɗaukar nauyin zafi.

② Babban Amfani:

Yana shaƙar zafi mai wucewa a cikin sarrafa Laser, yana rage ɗaukar nauyi a kan tsarin sanyaya.

Yana rage yawan kuzarin tsarin sanyaya ruwa da kashi 40%.

③ Aikace-aikace:

Laser mai ƙarfi mai ƙarfi (misali, lasers QCW), tsarin bugu na 3D tare da girgizar zafi na wucin gadi akai-akai.

3. Heat Bututu Thermal Yada: Hanya mai Wuce "Thermal Highway"

① Ka'idar Fasaha:

Yana amfani da bututun injin da aka rufe da ruwa mai aiki (kamar ƙarfe na ruwa), inda zazzagewar turɓaya da sauri ke canja wurin zafi a cikin ƙasa gaba ɗaya.

② Babban Amfani:

Ƙarƙashin zafi har zuwa 100 × na jan karfe (> 50,000 W/m·K), yana ba da damar daidaita yanayin zafi-makamashi.

Babu sassa masu motsi, marasa kulawa, tare da tsawon rayuwa har zuwa awanni 100,000.

③ Aikace-aikace:

Tsarukan diode Laser mai ƙarfi mai ƙarfi, daidaitattun kayan aikin gani (misali, galvanometers, ruwan tabarau mai mai da hankali).

4. Cooling na Jet Impingement: Babban Matsi "Mai kashe zafi"

① Ka'idar Fasaha:

Tsari na ƙananan nozzles suna fesa mai sanyaya a cikin babban sauri (> 10 m/s) kai tsaye zuwa saman tushen zafi, yana ɓata iyakar iyakar zafi da ba da damar canja wurin zafi mai zafi.

② Babban Amfani:

Ƙarfin sanyaya na gida har zuwa 2000 W/cm², wanda ya dace da laser fiber-mode-matakin kilowatt guda ɗaya.

Niyya sanyaya na wurare masu zafi (misali, fuskokin kristal na Laser).

③ Aikace-aikace:

Single-yanayin high-haske fiber Laser, mara kyau crystal sanyaya a ultrafast Laser.

5. Algorithms na Gudanar da zafin jiki na hankali: AI-Kinga "Kwakwalwar sanyaya"

① Ka'idar Fasaha:

Haɗa na'urori masu auna zafin jiki, mitoci masu gudana, da ƙirar AI don yin hasashen lodin thermal a ainihin lokacin da daidaita sigogin sanyaya (misali, ƙimar kwarara, zazzabi).

② Babban Amfani:

Haɓaka haɓakar makamashi na daidaitawa yana haɓaka haɓaka gabaɗaya da sama da 25%.

Kulawa da tsinkaya: nazarin yanayin zafi yana ba da damar gargadin farko don tsufa tushen famfo, toshe tashar, da sauransu.

③ Aikace-aikace:

Masana'antu 4.0 na fasaha Laser workstations, Multi-module a layi daya tsarin Laser.

Kamar yadda sarrafa Laser ya ci gaba zuwa mafi girma da ƙarfi da kuma mafi girma daidai, thermal management ya samo asali daga "fasaha mai goyan baya" zuwa "babban fa'ida ta bambanta." Zaɓin sabbin hanyoyin kwantar da hankali ba kawai yana haɓaka rayuwar kayan aiki da haɓaka ingancin sarrafawa ba amma kuma yana rage yawan farashin aiki sosai.
