Zorluk: OrtaCPU Architecture Cooling and Sockets

An IT technician is servicing high-performance desktop computers and reviewing thermal design features along with CPU socket mechanisms. Match each cooling technology or socket feature on the left with its corresponding technical operational characteristic on the right.

  • Thermoelectric Cooler (Peltier Device)Utilizes an active solid-state heat pump mechanism driven by electrical current to transfer thermal energy between two ceramic plates.
  • Vapor Chamber BaseEmploys a hollow, vacuum-sealed planar chamber containing liquid that vaporizes and condenses across a broad surface area.
  • Zero Insertion Force (ZIF) SocketUses a mechanical lever on a Pin Grid Array (PGA) socket to secure or release processor pins without mechanical resistance.
  • Direct-Contact Heat PipesExposes flattened copper heat pipes to sit flush against the integrated heat spreader (IHS) for direct thermal conductivity.

Cevap

Thermoelectric Cooler matches with the solid-state active heat pump mechanism using electrical current; Vapor Chamber Base matches with the planar vacuum-sealed liquid vaporization chamber; Zero Insertion Force (ZIF) Socket matches with the mechanical lever mechanism on PGA sockets; Direct-Contact Heat Pipes match with flattened copper heat pipes resting directly against the IHS.
Each component correctly aligns with its architectural or thermal design feature: Thermoelectric (Peltier) coolers utilize active electrical heat pumping; vapor chambers use a flat phase-change chamber for rapid thermal spreading; ZIF sockets use a lever mechanism to secure PGA pins without insertion force; and direct-contact heat pipes feature exposed copper tubing flush with the CPU heat spreader.

Adım Adım Çözüm

1
Identify the operation of active solid-state thermal pumps.
Thermoelectric coolers (Peltier coolers) rely on current passing through semiconductor junctions to move heat actively between two plates.
Understanding solid-state active thermal transfer distinguishes thermoelectric cooling from passive or fluid-recirculation systems.
2
Analyze planar phase-change heat distribution mechanisms.
Vapor chambers operate similarly to heat pipes but spread heat across a flat, two-dimensional sealed vacuum plane rather than along a narrow pipe.
Vapor chambers are ideal for high heat density areas due to their broad surface contact.
3
Evaluate PGA motherboard socket retention systems.
Zero Insertion Force (ZIF) mechanisms lock PGA processor pins in place with a side lever to prevent pin bending during installation.
ZIF sockets allow technicians to drop a PGA CPU into place with zero resistance before locking.
4
Differentiate direct-contact heat pipe cooler designs from traditional metal baseplates.
Direct-contact heat pipes eliminate the intermediate solid metal baseplate, placing exposed copper heat pipes directly against the processor heat spreader.
Direct contact reduces the thermal interface layers between the CPU heat spreader and the cooling fins.
