Features: Compact design offers excellent possibilities
for integration with existing equipment.
Efficient liquid heat sink thanks to inserted turbulators.
Liquid-Air system (LA)
Liquid-Air assemblies are used to cool or heat a liquid (or gas) flowing through a
heat sink. The liquid heat sink is designed for a recirculating system.
The heat is absorbed by the liquid heat sink, pumped through the TE modules,
and then dissipated to the air by an air heat sink.
Available in five standard versions, our PowerCool range delivers cooling
performance from 24 W to 160 W. Our Liquid-Air coolers provide compact and
reliable cooling/heating.
To improve heat transfer, turbulators are inserted into the liquid channels.
However, for higher liquid flow rates these may have to be removed to reduce pressure
drop.
Our liquid heat sinks are made of anodized aluminum. Should your application call
for another material in contact with your media, use a DA-assembly and mount your
own liquid heat sink.
Typical applications:
- Cooling of tissue or other areas of the body in laser or microwave thermo therapy.
- Cooling/heating in capillary electrophoresis.
- Cooling of power lasers and other sensitive electronics.

Specifications apply to ambient temperature 32°C and nominal Voltage. Tolerances ±10%
Ex = Example: At ambient 32°C and cooled space temperature 2°C
(deltaT = 30°C) the LA-045-12-02 (curve B) cools by 32% of its maximum effect,
which gives Pc = 43 x 0.32 = 13.8 W (±10%)
