As lightweight electrification accelerates across drones, electric vertical takeoff and landing (eVTOL) vehicles, and high-performance electric bikes, thermal management has become a critical bottleneck for range, reliability, and safety. High-power batteries, motors, and onboard electronics generate intense heat during operation, yet traditional cooling pumps are often too heavy, power-hungry, or bulky—directly compromising vehicle endurance and payload capacity. The Shinhoo EPL20L-01 is a purpose-built compact liquid cooling pump designed to address these exact challenges, delivering reliable, efficient performance for weight-sensitive applications.
Optimized for Low Power and High Efficiency
Engineered for maximum energy efficiency, the EPL20L-01 operates on 12V DC with a wide operating voltage range of 9–16V DC, making it compatible with most lightweight vehicle electrical systems. It delivers a rated flow of 10L/min at 1.72m head, with a maximum flow of 19L/min and maximum head of 2.0m—more than sufficient to cool mid-power batteries, motors, and electronic payloads. With a rated power of just 13W and a maximum power of 25W, this pump minimizes energy consumption, directly extending vehicle range by reducing parasitic loads. The speed range of 1000–3500rpm allows precise matching of cooling output to actual thermal demand, further optimizing efficiency.
Ultra-Compact and Rugged Design
Weighing only ≤320g (including rubber shock absorber), the EPL20L-01 sets a new benchmark for lightweight cooling solutions. Constructed from durable PPS+GF40 engineering plastic, it combines high strength with excellent corrosion resistance, ensuring long-term reliability in harsh operating environments. The pump features IP67 ingress protection, making it fully dust-tight and resistant to water immersion—critical for outdoor applications such as agricultural drones, industrial inspection UAVs, and electric bikes exposed to rain and mud. It operates reliably across an extreme temperature range of -40°C to 120°C, with a rated lifespan of ≥15,000 hours, significantly reducing maintenance and replacement costs. Noise is kept to a minimum at ≤40dBA (measured at 0.5m), ensuring quiet operation for both consumer and commercial applications.
Intelligent Control and Comprehensive Protection
The EPL20L-01 supports PWM precision speed control, allowing seamless integration with vehicle thermal management systems. It provides real-time PWM feedback signals, including a heartbeat signal for normal operation and diagnostic codes for fault conditions. The pump includes a full suite of protection features: dry run detection, locked-rotor/overcurrent protection, over-temperature protection, low-speed detection, and over/under-voltage protection. In the event of a fault, the pump will automatically attempt to restart according to a predefined schedule, and will shut down safely after 20 unsuccessful attempts to prevent damage. All fault conditions are communicated via the PWM feedback signal, enabling system-level monitoring and early warning.
Ideal for Weight-Sensitive Applications
Combining ultra-lightweight design, high energy efficiency, reliability, and intelligent control, the Shinhoo EPL20L-01 is the perfect cooling solution for:
Consumer and industrial drones: Cooling high-capacity batteries, cameras, and thermal payloads
Small eVTOL vehicles: Auxiliary cooling systems for batteries and onboard electronics
High-performance electric bikes: Cooling mid-drive motors and fast-charging batteries
Portable power stations: Thermal management for lithium-ion battery packs
Medical and industrial equipment: Compact liquid cooling for high-power electronics.
