What is a Vapochill and How Does It Work?
The VapoChill CPU cooling system, developed and manufaturered by asetek, is a technology designed and developed to increase PC-based performance using vapor phase cooling.
Four - fully integrated - components. The system or product
itself is both a CPU cooling system and a “barebone” PC platform on
which to configure Power PC systems and high end professional workstations.
A complete VapoChill system consists of four - fully integrated -
components:
1. Cooling unit,
2. CPU-kit,
3. ChillControl (electronic control unit), and
4. Case/front bezel
The system is designed to support all commercially available PC hardware.
25 - 60% above standard
performance. The proprietary VapoChill CPU cooling system or, more precisely
the cooling unit, utilizes the cooling effect of a liquid/gas phase change
system to dramatically increase CPU stability at high clock frequencies.
By using the VapoChill technology to cool standard Intel or AMD CPU's to subzero temperatures (-25 to -15 degrees Celsius), stable clock frequencies can be achieved at 25 - 60% above standard performance.
The fundamentally changed CPU operating conditions delivered by VapoChill supply
not only completely stable acceleration opportunities, but also elimination of
the normally occurring CPU circuit and transistor deterioration.
The physical phenomenon utilized in the VapoChill technology is scientifically
referred to as thermic
acceleration.
Private PC enthusiasts and
Professional end-users. Through the capacity to accelerate PC
performance to world record breaking benchmarks - litteraly - the VapoChill
product has found its customer base among private PC enthusiasts and demanding
professionals seeking or requiring the highest possible standards in PC
performance.
Where the private PC enthusiasts buy the VapoChill systems 'barebone' from traditional resellers, to build and configure their own unique PC systems, the professional and private end users requesting fully configured PC systems obtain their VapoChill-based PC's from specialist system integrators.
The Cooling cycle basically consists of the following four steps utilized in the normal operation of a Vapochill system.
-
Compression
-
Condensation
-
Throttling
-
Evaporation
Compression- compressor.
Gaseous refrigerant is sucked from the evaporator into the compressor. Pressure is raised to the condensation pressure of the refrigerant in order for the phase change to take place.
High
power not necessary
The choice of the 12
VDC compressor has several advantages. No high voltage solutions are necessary -
simply connect the cooling unit to an ordinary ATX power supply and make the
extra power cords to run the system obsolete.
The compressor has a low power consumption and thus a higher Coefficient Of
Performance compared to the 115 / 230 V cooling solutions on the market,
i.e. you need less power to remove the heat.
Size
DOES matter
With the Danfoss variable speed BD compressor series you get the most
compact and low-noise cooling unit with all the benefits you would miss
with other cooling solutions on the market. The compressor includes an
electronic unit which features overload protection and calibration of the
supplied voltage.
Condensation- condenser
Heat from from evaporator as well as heat included during compression is expelled through the condenser and is now
liquefied. Plates like a radiator disburse the heat and a fan is used as such. The
air for cooling the condenser is drawn from the front and hot air is expelled
through the back.
Fan
control and noise reduction
A large high quality fan is used to cool the condenser. The choice of
the larger fan makes it easy to adjust the fan speed to suit your cooling needs.
Adjustable fan speed makes noise problems easy to address.
Compact
condenser
Compact design combined with a very low pressure
drop across the condenser area ensures a low operating noise.
Well Engineered
Through careful design the cooling unit allows for an adjustable hose
length. Perfect adjustment to the CPU socket becomes an issue of the past. The
cooling unit is fully integrated into the case and you do not have to worry
about destroying your 100$ or above case in order to fit the unit.
Throttling- Capillary Tube
For the refrigerant to evaporate at a certain temperature, it is necessary to lower the pressure using a
valve. In this instance a capillary tube is used (tube with small inside
diameter) to obtain the same pressure drop before being sent into the evaporator.
Evaporation- evaporator
The evaporator transfers the heat generated by the CPU into the refrigerant,
where the refrigerant changes its phase from liquid to vapor.
Compact Design
Reduced in outside dimensions the evaporator technology (patent pending) is
capable of removing even more heat than our earlier design at the same
evaporator temperatures: -20 to -10 degrees Celsius, depending on CPU.
Easy to Use!
The overall CPU kit has been designed for a very easy change from one Socket-kit
to the other - an effortless operation that requires no professional assistance.
Design Details
The overall CPU kit is pre-assembled for easy installation - No harder to
install than an ordinary heat sink solution.
When mounted the design of the new CPU kit ensures a 100% even and permanent
pressure of the evaporator on the CPU.
The evaporator enclosure is metalized to effectively reduce permeability
Heat conduction compound, the high efficiency thermal paste, which is now part of the standard VapoChill Socket package, provides for maximum thermal acceleration and correct assembly of the CPU-kit.
