Which system does not get its cooling effect by turning a substance into a vapor?

There are a few techniques to cool something with out turning it into a vaporization.
The Peltier effect causes heat to migrate from one side of a junction between two metals to the other if a current is applied. Practically this cause one side to get hot and the other becomes cold.
cooling by conduction is another was to cool something. By circulating a cool liquid through a heat exchanger you can cool another stream that come in contact with the heat exchanger.
The last method that I can think of is a when stream of compresses gas is blown through an orifice and is subjected to a rapid pressure drop. This is how heat pumps and refrigeration cool their refrigerant but the gas does not have to vaporize for there to be a temperature drop. and prop in pressure in a stream of something will produce a corresponding drop in temperature.

What is necessary for your computer to have a liquid cooling system?
It is only necessary for your computer to have a liquid cooling system when a traditional fan cooling system is inadequate to cool the interior. This may be the case when overclocking components in a system, which causes more heat to be generated. Care should be taken, to avoid condensation from being generated, which may cause shorts.
If I buy a cooling fan for my Dell will it be fairly easy for me to fit it?
A new cooling fan for your Dell can be fairly easily fit into your system if you have a knowledge of computers and components. If not, an IT technician can easily do it for a fair price.
What is a Warm Reboot?
After the device is attached to the system, the end-user may reboot the system without turning off power to the system. This is referred to as a warm reboot.The USB device, device driver, and application software must be able operate after the warm reboot.
Your mustange is running hot what do you do?
does it have anti freeze in it? is the electric fan coming on or any fan? thermostat could be bad, or cooling system clogged, bad water pump?
What is the cofficient of performance in the refrigeration system?
Coefficient of performance, or COP, is defined differently for heating and cooling applications. For heating: COP=(heat supplied + work)/work For cooling: COP=(heat removed)/work Work in this case refers to the compressor and other motors.
What is the substance that absorbs and releases heat in a cooling system?
A refrigerant is a substance that absorbs and releases heat in cooling systems.
Can low engine oil effect the cooling system?
Low engine oil can effect the cooling system as it creates additional friction which may be difficult for the cooling system to remove. The oil is designed to both lubricate and cool the internal components.
Why do motorists put anti-freeze in the cooling system in winter?
To prevent the water turning into ice
How subcooling increase the COP of vapour compression refrigeration?
The sub-cooling or under-cooling in the saturated liquid line increases the refrigeration effect or cooling effect, thus the COP of VCR system increases.
What are effect of under cooling to the cooling system of the car?
Possibly over heating and worst case scenario a blown engine.
Why is there muddy substance on your radiators cap?
This is the result of a dirty cooling system. Corrosion is occuring in the engine block and a cooling system flush is required. Always use a good quality corrosion inhibitor in your cooling system to prevent overheating and possible head gasket damage.
What can be done about rust substance in coolant reservoir of 2001 Chevy Malibu?
Clean the reservoir and flush the cooling system.
How many ways can you think of in which electricity is used to cool objects or people?
electricity could be used to power; a refrigerator unit to cool fluids and foods, a cooling fan which circulates air to create a cooling - effect, a pump system which pumps water within a cooling system to reduce the heating effect of the objects.
What advantages are gained by pressurizing a cooling system?
High pressure means lower temperatures. You reduce the movement of molecules and hence less energy is in them. This leads to cooling effect. Pressurized cooling will be effective.
Does a 1999 Dodge Intrepid 2.7 have motor cooling system or not?
Motor cooling system? The engine cooling system consits of the water pump, radiator, hoses, cooling fans, etc.Motor cooling system? The engine cooling system consits of the water pump, radiator, hoses, cooling fans, etc.
Which system of the engine does the radiator belongs to?
The cooling system.
What is the average life of a system cooling device?
An average life of a system cooling device is around 10 to 15 years. This is with cont use of the system cooling device, if you do not use the cooling system then you can prolong your cooling system for a couple more years.
