Phase Change Technology use in the
ChillyDog
The Glacier Tek constant temperature vest is a
completely unique body management device. The unique cooling formulation
encapsulated in an anatomically designed CoolPack, makes a change in minutes
from a clear liquid to a semi-solid, white waxy form and maintains
= 59° F (15° C) throughout
its cooling cycle, and can be energized thousands of times. Unlike the extremely
cold temperatures of ice and gel, the higher temperature formulation in the
CoolPacks works in harmony with the body. When wearing an energized cool vest,
this cool phase change material heat sinks the excessive heat the body creates
when exercising, wearing protective clothing, encapsulating suites or just
working in HOT environments.
How does it feel?
When you first put an energized vest or jacket on, it feels cool, not cold.
Since skin temperature is approximately
92° F (33°
C), each individual will
react differently to its cooling sensation. Some individuals may feel a slight
cooling throughout the duration of the cooling life cycle, while others may not.
After approximately 30 to 45 minutes, some individuals may feel very little of
the “cooling sensation”. Why? Because the body is reacting very well to this
higher temperature and acclimating. Unlike the painful cold shock one feels when
ice or gel is placed against the skin, the
comfortable 59° F (15° C) temperature of the CoolPack feels more like
jumping into a swimming pool…. for the first few minutes it feels cool, and
then, as time passes, you hardly notice the sensation. Hence, the body has
acclimated to the cooler temperature.
Physiologically how does it work?
Basically, when the body needs to regulate its temperature, the brain triggers
vasodilatation of the blood vessels to increase the blood flow to the peripheral
skin areas of the body to stimulate sweating. An increase in heart rate occurs,
and the body begins its natural process of temperature regulation. As the
cooling formulation inside the CoolPack absorbs your body’s excessive heat, it
is cooling the soft tissues and blood as it circulates throughout the
cardiovascular system. As the blood and soft tissue become cooler, less
metabolic activity is required to meet the demand to regulate your body’s
internal temperature. By cooling the blood flow without vasoconstriction,
hypoxia is avoided and proper oxygen flow is maintained. Your body remains calm,
metabolic activity may slow, and less body fluids are forfeited maintaining
suitable electrolyte balance needed for proper muscle function and optimum
physical performance. Akin to a radiator in an automobile and automobile engine,
the formulation in the CoolPack absorbs and wicks away the bodies heat. As the
body’s engine becomes cooler, less heat needs to be
expelled. As its internal temperature is regulated and maintained, the
body experiences less stress, so the brain doesn’t trigger the need for
additional hyperactivity required to regulate the body’s temperature.
When wearing a Glacier Tek cool vest or jacket for heat stress relief, the
individuals will feel more energetic and alert. Phase Change Cooling Technology
is most effective when good thermal conductivity is maintained. A light Tee
shirt can be worn for Hygiene reasons, but is not necessary because of the safe
59°
F (15°C) temperature provided by the CoolPacks.
The Cool Jackets and Cool Vest were designed for the industrial safety market.
However their use has expanded to include Hazmat Teams, Foundries, under Bunker
Gear and Military Flak Jackets, Costume Characters and by workers required to
wear Chemical or Biological protective clothing.
The phase change material utilized in our Cool Jackets and Vest acts as a heat
sync to draw heat away from the user. If compared to an automobile, the heart
works like the water pump and the CoolPacks like the radiator cooling the entire
engine. When used properly the CoolPacks work systemically to help maintain a
safe core temperature.
The CoolPacks can be charged in Ice and Water in about 20 minutes or in a
refrigerator in 30 minutes. The CoolPacks are completely charged when the clear
liquid inside the packs turns into a White Solid. The CoolPacks continue to
maintain a 59° F (15° C) temperature as long as any portion of the Phase Change
Material remains solid within the pack.
Individuals will feel the initial cooling effect of the CoolPacks; However, It
is important to note that as the body becomes acclimated to the 59° F (15° C)
temperature the sensation of cool may decrease; However, the CoolPacks are still
drawing the heat away from your body. The effect experienced is similar to
jumping into a swimming pool, the initial coolness of the water seems to
decrease, but the water is still drawing the heat away from the body.
