Product Description
The 220W/K heat pipe enclosure heat exchanger is engineered for stable and energy-efficient thermal management in outdoor telecom cabinets, power distribution enclosures, industrial control panels, battery cabinets, and communication base stations.
Using advanced passive heat pipe technology, the system delivers reliable heat transfer performance with low power consumption, long lifecycle, and minimal maintenance.
▼heat pipe cross section 3D view ▼
There is no compressor,but heat pipe with Microchannel heat exchange core


The waste heat generated from the internal equipment will be absorbed by the refrigerant
through the evaporator and dissipate to the ambient by the condenser of external side.

Prevents dust, moisture, oil mist, salt spray, and corrosive pollutants from entering the cabinet
Ideal for IP65 outdoor telecom cabinets and roadside enclosures
Efficient heat transfer with no mechanical compressor
Stable operation in high ambient temperature conditions
Ultra-low energy consumption
Very low failure rate due to passive heat transfer mechanism
Minimal maintenance required
Designed for environments from –40°C to +55°C
Optional heater available for cold regions
Compact structure
Supports both panel-mount and door-mount installation
RS-485 communication and alarm outputs available

| Cooling Technology | How It Works | Advantages | Disadvantages | Best For |
|---|---|---|---|---|
| Heat Pipe Cabinet Heat Exchanger | Transfers heat through sealed heat pipes using phase-change circulation. Closed-loop design keeps internal air isolated. | • Very low power consumption• No compressor → high reliability & long life• Closed-loop prevents dust, moisture, and contaminants• Low noise, minimal maintenance• Great for harsh outdoor environments | • Cannot cool below ambient temperature• Limited cooling capacity vs. AC• Performance depends on ambient temperature difference | Outdoor telecom cabinets, battery cabinets, industrial enclosures, remote sites with limited maintenance access |
| Plate Air-to-Air Heat Exchanger | Heat is exchanged through conduction between two air streams separated by plates. | • No refrigerant required• Simple structure and easy maintenance• Long service life• Eco-friendly and energy-saving | • Lower heat transfer efficiency than heat pipe• Not ideal for high outdoor temperatures• Requires higher airflow• Internal air not fully isolated (open-loop versions) | Indoor or semi-outdoor cabinets, mild climate regions, medium heat-load electronics |
| Traditional Air Conditioner (Compressor Cooling) | Actively cools the enclosure using refrigerant and a compressor, similar to room AC. | • Strongest cooling capacity• Can cool below ambient temperature• Effective in very hot climates or high heat density cabinets | • Highest power consumption• Requires regular maintenance (filters, refrigerant, components)• Higher failure rate than passive exchangers• More expensive to operate and install | High-heat-load enclosures, hot climates, precision temperature-controlled environments, indoor telecom rooms |
