Development of Aluminum Heat Exchanger

Aluminum heat exchanger have emerged in recent decades. Aluminum boiler heat exchanger mainly started in Europe, and with the promotion, it entered the Americas, Asia and other regions.
With the improvement of boiler technology, cast iron boilers, copper boilers and steel boilers appeared. The improvement of furnace cooling requirements and the emergence of energy-saving awareness led to the invention of condensing heat exchanger boilers, which further improved the utilization rate of thermal energy.
But whether it is steel, copper or cast iron boilers, the corrosion resistance to acidic condensate is relatively poor. Just like our copper water heaters, if a little condensate is produced, the copper pipes will corrode, leak and be scrapped in a short time. So people have to look for more suitable materials for this heat exchanger. Not only are there requirements for corrosion, but also for thermal conductivity, manufacturability, and dexterity.
At that time, the automobile industry had been greatly developed, especially the development of the engine block, which had a great inspiration for the boiler heat exchanger. At that time, the automobile industry had been greatly developed, especially the development of the engine block, which had a great inspiration for the heat exchanger of this boiler. On the basis of the material of the cylinder block, great improvements have been made. Through a lot of experiments, we have obtained this corrosion-resistant material.
The characteristics of this heat exchanger are small size, large heat exchange surface area, compact structure and high thermal efficiency. The performance of the heat exchanger directly affects the entire product. Various tests and inspections in production are related to the key factors of product performance and service life. The general production inspection requires more than 40 processes to effectively ensure the quality of the product.

Aluminum heat exchanger are required to be as complex and dense as possible. The requirements for the factory are a bit high, and the formulation of the casting process is relatively strict. The point is to control the difference of each product within the allowable range of error.
