Heat Exchanger

1.Why heat exchangers are needed?

Generally speaking, as electronic components get tinier and more powerful, the amount of heat they generate gets proportionately higher. This is due to the simple fact that there’s just not enough surface for the heat to dissipate quickly enough. That’s why all computers’ processors and high-end video cards come with a heat sink with a fan on top. Take this heat sink away and you’d fry the component in a matter of seconds.

Within industrial plants and factories heat exchangers are required to keep machinery, chemicals, water, gas, and other substances within a safe operating temperature.

Engineers who work with hydraulic systems on a regular basis are well aware of the critical need for effective, efficient cooling of the hydraulic oil. Maintaining a proper oil temperature is imperative-the consequences of ignoring this factor are dramatic and often catastrophic! Elastomeric seals and hoses become hard and brittle when exposed to excessive temperatures and will begin to leak. Piston pumps and servo/proportional valves (which typically rely on tight tolerance metal-to-metal interfaces for internal moving parts) will fail due to loss of viscosity of the oil as it thins or breaks down. The hydraulic system performance will then degrade or fail completely when any of these occur.
