Solution: DC Chiller DV2820E-P(T) 

The 24V Recirculating Water Chiller DV2820E-P (T) adopts environmental refrigerant R290. It is a promising solution for your cooling requirements. It utilizes an aluminum heat dissipator with circulating water to effectively dissipate heat from your electronics. Here are some key features and specifications:

  • Cooling Power: The chiller provides the necessary cooling power of 500W to match heat generation.
  • Flow Rate: A flow rate of 2 liters per minute is sufficient to maintain the desired temperature.
  • Temperature Control: While the standard chiller does not include temperature control, it offers the flexibility to add a thermostat if needed. This allows you to precisely regulate and maintain the temperature of the circulating water.

Customer Comments

“Our primary obstacle centered on cooling the diodes. When we’re working with laser diodes producing 1kW of optical output, we must dissipate around 500 Watts of heat to maintain a diode temperature of 25 degrees Celsius. Traditional standalone laser chillers, which are three times the size of our enclosure, were quickly ruled out,” noted Michael.

We explored Thermal Electric Cooling (TEC) as an alternative but soon encountered significant limitations. The size remained too bulky to integrate into our enclosure, and the efficiency left much to be desired. TECs generated over 1 kW of heat, which needed to be expelled into the room. To mitigate this, we had to install large fans, but they proved too noisy for use in a clinical setting.

“RIGID’s compact chiller systems have proven to be the perfect fit for our needs – compact size, lightweight, high efficiency, and noiseless operation,” Michael affirmed. “The inclusion of RIGID’s small refrigeration unit has played a pivotal role in our success. Thanks to the RIGID chiller, we can now proudly offer our Hpc (High Power Cooling) technology, which has become a reality.”

DC Inverter Chiller Applications 

Electronic components generate heat during operation, and if not properly managed, this excess heat can lead to performance issues and even damage. In your case, you are dealing with electronics that produce 16W of heat power. To maintain them at a safe operating temperature, you need an efficient cooling system.
