Precision Machining and Testing Improve Heat Exchanger Reliability

A heat exchanger is used to regulate temperature by transferring heat from fluid to fluid; gas to fluid; fluid to gas; or gas to gas. These devices come in a broad range of sizes and configurations and use various techniques to perform their functions.

Heat exchangers are designed according to whatever a particular application requires. “Shell-and-tube” style heat exchangers, which can be very large, are used in power generation plants and petroleum refineries. But variations of this type of heat exchanger are also used in home air conditioning units.

Building a Better Radiator

“Scraped surface,” “phase change” and “double pipe” are other styles of heat exchangers. But regardless of the classification or heat transfer method, these apparatuses are susceptible to problems such as leaks or fouling — the buildup of dirt and debris — if they are not well-maintained.

The automobile radiator, for example, is the most widely-known and used type of heat exchanger. It is well known that cars and other motor vehicles can experience serious performance issues when radiators are leaky or become clogged with debris. However, great strides have been taken in creating sturdier and more efficient radiators using the precision machining and assembly equipment that we have available today.

Computer imaging technologies are now employed in the planning and construction of radiators. Special automation equipment that incorporates advanced core builder machines and fin mills are also used for radiator assembly. These state-of-the-art systems — combined with the latest flow and leak testing equipment — are capable of producing higher quality, longer lasting radiators than ever before.

The architecture surrounding radiators and heat exchangers of every style continues to evolve. And with the cutting-edge machinery now used in the manufacturing process, innovations in heat exchanger design are quickly becoming a reality.
