Frequently Asked Questions
What alloy is used in the SRQ-XJ-25 extrusion and what is its thermal conductivity?
The SRQ-XJ-25 is extruded from a high-purity aluminum alloy, typically 6063-T5, which offers a thermal conductivity of approximately 200 W/m·K. This alloy provides an excellent balance of thermal performance, extrudability for complex fin profiles, and mechanical strength for industrial mounting applications.
Can the SRQ-XJ-25 profile be used as a structural chassis element as well as a heat sink?
Yes. Extruded aluminum heat sink profiles are commonly used as structural elements in power electronics enclosures, serving dual roles as thermal management components and mechanical chassis members. The SRQ-XJ-25's robust cross-section supports this approach, reducing overall system part count and assembly cost.
How do I select the correct length of SRQ-XJ-25 for my power dissipation requirement?
Thermal resistance decreases approximately proportionally with length for extrusion profiles in forced-air cooling, and with diminishing returns in natural convection beyond a certain length. CZT provides thermal resistance per unit length data to support sizing calculations. Share your power dissipation, ambient temperature, and airflow conditions for a recommendation.
