Industrial / Heat Sinks
SRQ-HJ-15
The SRQ-HJ-15 (SRQ-HJ-15) is an industrial heat sink engineered for high-efficiency thermal dissipation in space-constrained electronic enclosures. Its extruded aluminum fin profile offers an excellent strength-to-weight ratio while maintaining low thermal resistance, making it a preferred choice for DIN-rail mounted controllers, frequency converters, and compact power supplies. The SRQ-HJ-15 supports both passive and low-velocity forced-air cooling configurations.
Key Features
- High-efficiency thermal dissipation optimized for space-constrained installations
- Slim profile enables deployment in 1U rack and compact enclosure formats
- Extruded fin structure maximizes surface-to-volume ratio within tight footprints
- Compatible with both natural convection and low-velocity forced-air cooling
- Precision base flatness reduces thermal interface resistance at device contact

Frequently Asked Questions
How does the SRQ-HJ-15 perform in low-airflow environments?
The SRQ-HJ-15 is engineered to deliver effective passive cooling even in low-airflow conditions by maximizing fin surface area within its compact envelope. For applications with near-zero airflow, thermal derating should be applied per the datasheet curves to ensure junction temperatures remain within safe limits.
Is the SRQ-HJ-15 compatible with 1U server or rack enclosures?
Yes. The slim profile of the SRQ-HJ-15 is specifically suited for 1U and 2U rack-mount enclosures where vertical clearance is limited. Verify fin height against available chassis clearance before installation to ensure unobstructed airflow through the fin channels.
Can the SRQ-HJ-15 be cut or machined to custom lengths?
Extruded aluminum heat sinks like the SRQ-HJ-15 can generally be cut to custom lengths using standard metalworking tools. Deburring cut edges is essential to prevent fin damage and maintain airflow efficiency. Contact CZT for pre-cut custom length options if volume requirements justify it.
