How does heat capacity makes water a good heat sink?

If a body of water has a high heat capacity, it can store more thermal energy making it a good heat sink.


How can heat be tranferred to areas?

Heat is normally transferred to specific areas by means of a 'heat sink' which is usually made of a material with low resistance and high transfer of heat. An example of this can be seen in most computers, the heat sink collects the heat from the processor, and there is (usually) a fan which is near or on the heatsink to remove it from the heat sink, effectively lowering the temperature of the processor.


Which objects will be touching thermal paste?

Heat sink and CPU


How would you increase the efficiency of a Carnot engine by increasing T1 or by decreasing T2 - why?

Increasing the temperature of the hot reservoir will increase efficiency. So will decreasing the temperature of the cold reservoir (heat sink). There are limits as to how cold you can get the heat sink however. Cutting the temperature of the heat sink in half will give the same improvement in efficiency as doubling the temperature of the heat source - but it's a lot harder to cut the temperature of the heat sink in half than to double the temperature of the heat source. Also, the heat sink is usually around the temperature of the environment - which you have little control over. ... bottom line - you are probably going to find it easier to improve the efficiency by raising T1 than by decreasing T2.


How many watts per hour with a heatsink attached?

It depends on the size of the heat sink. Heat sinks are available in many sizes, the smallest being suitable for fitting to a single transistor. A heat sink is rated by the temperature rise in degrees C per watt of dissipated power. The smallest heat sinks are rated at about 20 degrees per watt while larger ones provide 1 degree or less per watt.

How can you tell if it's uses active or passive cooling by looking at the CPU?

The difference is that Passive cooling is just a heat sink that dissipates the heat into the air without the help of a fan. Active cooling is when you have a heat sink and a fan is directly blowing/sucking air thru the heat sink to cool it. The fan does not have to be on the heat sink as with some dell/gateway computers. The fan is on the plastic shroud, which in turn fits right over the heat sink. Water cooling and phase-change cooling is also considered active cooling.


Diffrentiate between active heatsink and passive heatsink?

In a active heatsink system you have both a heatsink and a fan thus for the most part an active heatsink cools better with one exception. Should the fan fail the active heatsink will quickly overheat. Passive heatsinks relay on transferring heat without the aid of a fan. The advantage here is that a passive heatsink is fail proof and uses 0 electricity, however passive heatsinks don't typical cool as well. Passive heatsinks work great for supporting chips and RAM cooling. They are also found in servers because of the no fail aspect. EnzoTech produces some passive heatsinks you can read a bit more about them here: http://electricalninja.com/


What are the functions of the heat?

The main purpose of a heat sink is to expel heat from a generating source. Heat sinks work through the process of conductive and convection heat transfer. Heat sinks are a passive form of cooling, as they have no moving parts and require no power.


What is the function of a processor heat sink?

To sink the heat.


What is heat sink compound used for?

The heat sink compound is a mechanical component usually made of copper or aluminium or other heat conductive material. It's main purpose is a passive cooling of a body it is attached to, usually a computer chip or processor. It do not require any mechanical parts or power and significantly reduce the noise level.


Why is a sink called a sink?

Probably because it draws/absorbs the heat making the heat "sink" into it


How does a heat sink work in the power supply?

A heat sink works on the principle of thermal transfer. The heat sink transfers heat from the chip to the air, wicking heat away.
