Thermalblock heat rejection as opposed to heat resistance

Understanding Thermal Management in Critical Equipment

The Impact of Heat on Equipment Life

• At Codezone, the focus is on protecting critical equipment by reducing thermal stress across HVAC systems, telecommunications infrastructure, and electrical distribution.

• Elevated temperatures significantly shorten equipment life; most industrial electronics operate best between 20 to 25°C (68 to 77°F), with a maximum continuous limit of around 40°C (104°F).

• For every sustained increase of 10°C in operating temperature, component life is reduced by approximately 50%, leading to higher maintenance costs and unplanned downtime.

Challenges with Traditional Insulation

• Commonly used metal enclosures absorb heat from solar load and harsh environments, raising internal air temperatures and stressing components.

• Traditional insulation degrades over time due to moisture intrusion, UV exposure, dust, and physical wear, ultimately failing to provide adequate thermal resistance.

• Once insulation fails, it cannot remove heat or lower internal temperatures; it merely slows down the next wave of incoming heat.

The Need for Effective Thermal Strategies

• There is a crucial distinction between resisting heat and rejecting it; most thermal strategies fail because they only resist rather than reject heat.

• Thermal Block is introduced as a solution that prevents radiant and conductive heat from entering equipment by rejecting thermal energy at the surface.

Benefits of Using Thermal Block

• In field applications under solar exposure, Thermal Block has shown exterior surface temperature reductions of 16 to 20°C (60 to 68°F), leading to lower internal enclosure temperatures.

• Lower internal temperatures result in reduced thermal stress on electronics and PCBs, decreased cooling demand, measurable energy savings, improved reliability, extended service life, fewer maintenance events, and overall lower energy consumption.
