Air Oil Cooler-Benefits And Applications Of Air Oil Cooler

Air oil cooler Manufacturers in India

Air-oil coolers are those that use a draft of ambient air to draw heat from a fluid, usually oil. They are a form of heat exchanger commonly found in automobiles that do not have a liquid coolant supply such as automotive and construction vehicles. These heat exchangers use air to cool fluids that are guided through a fin core by an electrical, hydraulic, or mechanically driven fan. The fluid, generally oil or water-glycol moves through a cooler. A fan draws air and guides it through the cooling element. So, there is a temperature difference and heat exchange occurs resulting in a rise in air temperature which is then emitted into the atmosphere. This process decreases the actual temperature of the fluid by a few degrees over the actual environmental temperature. And we are leading Air oil cooler Manufacturers in India.

They usually include a fan, a heat exchanger, an exterior frame, and certain instrumentation such as a temperature gauge and temperature and pressure switches.

Working

It employs a significant number of rectangular tubes formed by brazing together Aluminum alloy plates, sidebars & inside bars. The oil to be cooled enters through an inlet header and is then spread through these rectangular tubing. Internal fins are embedded inside these rectangular tubes. The heat is passed from the oil to these fins. The heat is then transferred from the internal fins to the plates. Between each pair of plates are external fins and the heat is transmitted from the plates to the external fins through conduction. A cold ambient air draft is pushed through the external fins, taking away the heat.

This kind of heat exchanger is often referred to as a compact heat exchanger due to its comparatively high heat transfer surface area to volume ratio. Plate-fin heat exchangers are commonly used in many industries due to their small size and lightweight, as well as their ability to allow heat transfer even though the temperature range between the hot and cold fluids is small. The internal and external fins, in addition to raising the surface area for heat transfer, help to improve the structural stability of the air-cooled heat exchanger and allow it to withstand higher pressures and pressure fluctuations. The oil that has been cooled in the rectangular tubes pools in the outlet header and leaves the heat exchanger.

Benefits:

  • A significant advantage when using air oil coolers is their lightweight construction as opposed to most coolers on the market, this is very advantageous because it allows this heat exchanger to be comfortably carried and brings in less strenuous requirements when applied to any device.
  • Air oil coolers often need less ground space than other heat exchangers, making them ideal for use in small spaces and allowing for a wide range of applications in a variety of industries.
  • This kind of cooler works by forcing the cold air over hot fluid within the coil or center of a heat exchanger. Low operating costs and easy maintenance are enticing advantages of air-cooled systems. They also remove water runoff and reduce corrosion. Furthermore, the heat generated by air-cooled systems may be used for other purposes.

Disadvantage

In the drawback, The biggest drawback is that an air-cooled machine has a higher initial cost. Air-based models are also bigger and noise which can degrade the working environment. Furthermore, these coolers need ventilation and clean air, and fluctuations in atmospheric temperature may have a substantial effect on cooling power, rendering steady-state operation more difficult to sustain.

Application

Air-oil coolers are useful in hydraulic systems, factory automation, hydraulic power packs, heat recovery, air compressors, diesel engines, gearboxes, hydraulic wrenches, construction stone crashers, heat recovery, and the renewable energy industry for power generators and wind turbines.
