Cooling devices are those equipments that are used to transfer thermal energy from one medium to another and their main purpose is to keep the environment cool as compared to the normal temperature. the Some of the cooling devices that are available in the market are:

• Heat exchanger: A heat exchanger is a device that is designed for the purpose of efficient heat transfer from one medium to another. In this case, the media is either separated by a solid wall so that the transfer of heat is done at a biased level, or the media are in direct contact.
• Radiator: Radiators come under the category of one of those heat exchangers that are especially crafted for the purpose of transferring thermal energy from one medium to another. And these are meant for the purpose of cooling and heating.
• Intercooler: These come under the category of those air-to-air that are especially designed so that they can be used on turbocharged as well as supercharged internal combustion engines. These are also meant for the purpose of air-to-liquid devices as well.
  
  Basically meant for the purpose of heat exchange.
• Charge air cooler: It is basically used to cool engine air after it has passed through a turbocharger, but the device has to make sure that the process is completed before the air enters the engine.
