Background

Electric vehicle lithium battery cooling has evolved from basic air cooling to sophisticated liquid cooling systems. The rise of lithium-ion batteries brought attention to thermal management, with liquid cooling emerging as a more efficient solution. Direct and indirect liquid cooling methods are utilized, providing better heat dissipation and temperature control.

Ongoing research explores advanced thermal management technologies, integrating them with vehicle systems for dynamic adjustments. The evolution reflects a commitment to enhancing efficiency, safety, and overall performance in electric vehicle battery cooling solutions.

An American customer is looking for a RIGID water-to-water liquid chiller system to cool lithium batteries in a compact electric vehicle prototype. The system needs to fit within specific dimensions (400mm x 180mm x 300mm) and provide up to 800 watts of cooling while being compatible with a 48Vdc power source.

Key requirements include effective temperature regulation on both the condenser and evaporator sides, accommodating varying inlet temperatures. The customer values energy efficiency (maximum 400 watts) and a quiet operation, aiming to cool batteries and electronics.

After a thorough analysis, the customer chose the customized chiller model DV3830E-P-T(custom) over alternatives like KVB096Z-48, considering factors such as cooling capacity, electrical consumption, and pricing within RIGID’s product range.

Solution

48V PLATE LIQUID CHILLER: DV3830E-P-T
  • Voltage: 48V DC
  • Refrigerant: R290
  • Net Weight: 6.0kgs (13.23lbs)
  • Compressor Cooling Capacity: 750W
  • Compressor: 48V mini compressor (Dual-cylinder)
  • Applications: Custom Micro Refrigeration Systems that Provide Compact yet Powerful Thermal Management Solutions.

RIGID’s water chillers operate on vapor compression refrigeration principles. The process begins with refrigerant evaporating in the evaporator coil, absorbing heat from water or fluid.

The compressor then raises the refrigerant’s temperature and pressure. In the condenser coil, heat is released to the external environment, causing the refrigerant to condense. After expansion, the low-pressure liquid returns to the evaporator.

Chilled water passing through the evaporator absorbs heat, and the cycle repeats. For specific details or need customized service, do not hesitate to contact us. We are sure you will receive a prompt reply from our engineers.
