Water-cooled units for commercial vehicles utilize coolant as the cooling medium, circulating through key components like compressors, evaporators, condensers, expansion valves, and plate heat exchangers. They absorb heat from batteries and motors, regulating cooling efficiency by adjusting coolant temperature and flow.
From basic radiators to intelligent control systems, advancements in materials and technology have enhanced cooling efficiency and enabled stable operation in extreme temperatures (-30°C to +80°C). Stringent environmental standards drive continuous innovation toward lower energy consumption and higher COP (≥2.5).
Available in 5KW to 16KW models, each unit is tailored for specific applications:
- 5KW Unit: Lightweight (≤40kg), with PTC heater (6-14KW), 4 working modes (standby, cooling, heating, self-circulation), and CAN 2.0 communication.
- 8KW Unit: 8KW cooling capacity, IP67 protection, and networked control for medium-duty vehicles.
- 10-16KW Units: High-power solutions for heavy trucks, construction machinery, and energy storage systems, with optional PTC heating and large coolant flow (≥45L/min).
Selection depends on battery capacity and thermal management needs (e.g., battery+AC, battery+AC+motor cooling). Take the 5KW unit as an example:
- Working temp: -30°C to +80°C
- Coolant: 50% ethylene glycol/water
- Refrigerant: R134a (350±5g)
- Noise: ≤85dB
- Compact design for small new energy vehicles.
- New Energy Commercial Vehicles: Maintains optimal temperatures for batteries, motors, and ECUs in buses, trucks, and construction equipment, extending battery life and improving efficiency (e.g., King Long buses, Dongfeng trucks).
- Energy Storage Stations: Regulates battery temperatures to enhance energy storage efficiency.
- Other Fields: Supports charging piles, 5G base stations, server liquid cooling, and hydrogen energy systems.
Comprehensive tests ensure reliability:
- Cooling efficiency & refrigeration capacity verification
- Leakage & pressure resistance tests
- Electrical safety checks (IP67 protection)
- High/low-temperature durability cycles
As cooling specialists, these units drive sustainable development:
- Enabling eco-friendly transportation in buses and trucks
- Optimizing construction machinery performance
- Boosting clean energy storage efficiency
From 5KW to 16KW, these units combine technical innovation with strict quality control, paving the way for a low-carbon future in new energy sectors.
