Precision drawn profiles, or spacer bars, are used in plate-and-bar heat exchangers. Such heat exchangers can be built entirely in aluminium. This versatile concept is typically used in heavy equipment, due to its ability to withstand relatively high wear and tear, and for its high corrosion resistance.
The aluminium spacer bar is extruded and drawn under carefully controlled conditions. We usually supply these parts in long lengths, in a temper that allows you to handle the parts without bending them. You then cut the parts into the length needed.
The technology offers this solution high degrees of flexibility, so that the heat exchanger can be fitted to the actual need, even in low volumes.
The plates are used as building blocks in plate-and-bar heat exchangers. They are normally the final pieces added. Consequently, achieving the dimensional tolerances is critical, because any deviations from the nominal target will be multiplied by the number of profiles used in the application.
In typical plate-and-bar designs, you will adjust the length of the “block” to fit the depth of the heat exchanger, and adjust the “long bar” to the length.
When you choose precision drawn profiles from Hydro, you are choosing a full-service supplier that offers you:
Excellent energy absorption is one of the properties that carmakers, and insurance companies, value in Hydro’s range of aluminium specifically designed for cars and the automotive industry. Aluminium from Hydro can make your vehicles safer.
Using aluminium for a car’s structure can lessen weight by as much as 30% compared to steel. As aluminium is fully recyclable, a large percentage of the car of the future could be made from 100% recycled aluminium, a truly sustainable vehicle.
Hydro designs and manufactures aluminium components for all passenger cars and commercial vehicles.
