A vapor compression phase-change cooler is a unit that usually sits underneath the PC, with a tube leading to the processor. Inside the unit is a compressor of the same type as in an air conditioner. The compressor compresses a gas (or mixture of gases) which comes from the evaporator (CPU cooler discussed below).
Lasance and Eggink [13] also found that for the bypass configurations that they tested, the flared heat sink performed better than the other heat sinks tested. Free-convection flow around a pin-fin heat sink. Generally, the more surface area a heat sink has, the better its performance. [2] Real-world performance depends on the design and ...
To better understand the problem we must remember the basic concepts underlying Thermal management and Computer cooling. [26] Let’s consider the thermal conduction path from the CPU case to the ambient air through a Heat sink, with: Pd = Thermal power generated by a CPU and to be dissipated into the ambient through a suitable Heat sink.
A Cooler Master computer heat sink has many heat pipes. CPU cooler Thermalright Le Grand Macho RT installed into the computer case. Air cooling is a method of dissipating heat. It works by expanding the surface area or increasing the flow of air over the object to be cooled, or both.
For example, building the CPU out of better, faster transistors. However, sometimes pushing one type of performance to an extreme leads to a CPU with worse overall performance, because other important aspects were sacrificed to get one impressive-looking number, for example, the chip's clock rate (see the megahertz myth ).
AMD Wraith is a family of downdraft type CPU coolers designed by AMD. The Wraith was introduced as a heatpipe-equipped stock cooler for certain AMD FX CPUs and AMD A-series APUs. With the launch of AMD Ryzen, the Wraith lineup has been updated to four new variants, varying in design, cooling capabilities, and lighting features.
Liquid cooling is also used to remove heat from large buildings by using chillers which transfer the coolant from the evaporator to air handling units, chilled beams and fan coil units inside the building, and to the cooling towers from the condenser if the condenser is liquid-cooled.
A small blower fan is used to direct air across a laptop computer's CPU cooler. A case fan may be mounted on a radiator attached to the case, simultaneously operating to cool a liquid cooling device's working fluid and to ventilate the case. In laptops, a single blower fan often cools a heat sink connected to both CPU and GPU using heat pipes.
