Kev tswj qhov kub thiab txias tau muab faib ua cov tshuab thiab hluav taws xob.
Hluav taws xob tswj qhov kub thiab txias hloov feem ntau siv thermistor (NTC) raws li qhov ntsuas kub ntawm lub taub hau, qhov kev tiv thaiv tus nqi ntawm cov thermistor hloov nrog qhov kub thiab txias, cov teeb liab thermal rau hauv hluav taws xob teeb liab. Qhov kev hloov pauv no dhau los ntawm CPU, tsim cov teeb liab tswj cov zis uas thawb lub zog tswj kom ua haujlwm. Lub tshuab ntsuas kub tswj kev hloov pauv yog siv cov ntawv bimetallic lossis kub nruab nrab (xws li kerosene lossis glycerin) thiab lub hauv paus ntsiab lus ntawm thermal expansion thiab contraction, qhov kub thiab txias hloov mus rau hauv mechanical quab yuam, los txhawb qhov kub thiab txias hloov tswj mechanism ua haujlwm.
Mechanical kub hloov yog muab faib ua bimetallic kub hloov thiab kua expansion kub xws li.
Bimetallic sheet temperature switches feem ntau muaj cov npe hauv qab no:
Kub hloov, kub tswj, kub hloov, dhia hom kub tswj, kub tiv thaiv hloov, kub tiv thaiv, lub cev muaj zog tiv thaiv thiab ntsuas kub, thiab lwm yam.
Classification
Raws li kev tswj qhov kub thiab txias yog cuam tshuam los ntawm qhov kub thiab txias tam sim no, nws tau muab faib ua ntau hom kev tiv thaiv kub thiab tshaj qhov kub tiv thaiv hom, lub cev muaj zog tiv thaiv feem ntau yog kub thiab dhau tam sim no tiv thaiv hom.
Raws li kev khiav hauj lwm ntawm qhov kub thiab txias hloov pauv thiab qhov rov qab qhov sib txawv ntawm qhov kub thiab txias (tseem hu ua qhov sib txawv ntawm qhov kub thiab txias amplitude), nws muab faib ua hom kev tiv thaiv thiab qhov kub thiab txias. Qhov kub sib txawv ntawm kev tiv thaiv qhov kub thiab txias hloov yog feem ntau 15 ℃ to 45 ℃. Qhov kub ntawm qhov sib txawv ntawm qhov ntsuas kub yog feem ntau tswj tsis pub dhau 10 ℃. Muaj cov ntsuas kub qis qis (qhov kub sib txawv hauv 2 ℃) thiab cov ntsuas kub ceev nrawm (qhov kub sib txawv ntawm 2 txog 10 ℃).
