Radiator Cooling Liquid Cold Plate Tube To Fin Heat Exchanger To Dissipate Heat From Power ElectronicsS

Radiator Cooling Liquid Cold Plate / Tube To Fin Heat Exchanger

Tube to fin heat exchangers, also referred to as radiators, are made with copper, stainless-steel or aluminum tubes that pass through the highest density fin stack that is supported by a mounting frame. These fins can be made of copper or aluminum. This allows designs to maximize heat transfer from liquid to air.

Tube to fin heat exchangers are cost effective, offer good heat removal and are used in many industries including military and aerospace, medical equipment, lasers, analytical instrumentation, power electronics, semiconductor equipment, machine tools, telecommunications, imaging devices, HVAC, food and beverage processing and more.

Radiator cooling/ tube to fin heat exchangers, allows liquid to be cooled to much lower temperatures than many other types of solutions. The tubes are suitable for a variety of fluids, including water, dielectric fluids and specific blends for a customer’s custom application.

Fin heat exchangers provide a significantly increased surface area due to numerous thin fins situated in the thermal path. They are very suitable for dissipating excess heat in liquids to the ambient air or a second cooling circuit.

Baknor’s heat exchanger designs are available in a number of sizes and can be designed with or without a fan. Our thermal experts can specify and design a customized heat exchanger solution tailored specifically to your needs. A high degree of flexibility is available to tube to fin heat exchanger designs. They can operate with any combination of gas, liquid, and two-phase fluids. Heat transfer between multiple process streams is also accommodated. A variety of fin patterns, bend densities, mounting structures, and pipe connections are readily available for fabrication.

The heat exchanger coils are available in virtually any size from 5 cm x 5 cm to 2 m x 5 m. Its tube-fin constructions can be equipped with tubes from many different tube patterns and tube diameters in 5 mm, 7 mm, 3/8” or ½”.

Special options include Nano-coating that prevents dust accumulation, a cost-effective aluminium tube construction suitable for ultra clean water or highest-grade stainless-steel tubes suitable for sea water among others.


  • High heat transfer efficiency especially in gas treatment
  • Larger heat transfer area
  • Approximately 5 times lighter in weight than that of shell and tube heat exchanger.
  • Able to withstand high pressure
