← TechnologyWhich outcome occurs when a thermoelectric cooler's (TEC) heat sink fails?
A)Hot side temperature will elevate✓
B)Cooling capacity improves marginally
C)Cold side achieves lower temperatures
D)System efficiency remains unaffected
💡 Explanation
A failed heat sink in a TEC causes heat to accumulate on the hot side because of the Peltier effect unable to dissipate the rejected heat; therefore, the hot side temperature rises, rather than improved cooling or unaffected efficiency under normal operation.
