A sealed thermos containing hot coffee is a good example of an isolated system because it minimizes the exchange of heat with the surroundings. Another example is an insulated ice chest containing ice, as it also limits the transfer of heat in or out of the system.
Countercurrent exchange maximizes heat transfer between two fluid streams by maintaining a steep concentration gradient throughout the exchange process, resulting in more efficient heat transfer. This mechanism allows organisms to conserve energy by reclaiming heat from outgoing fluids and transferring it to incoming fluids. It is commonly seen in biological systems like fish gills and mammalian kidneys to optimize heat exchange and maintain homeostasis.
Radiative exchange refers to the transfer of heat through electromagnetic radiation between two surfaces at different temperatures. This process can occur in a vacuum and does not require a medium for heat transfer. The rate of radiative exchange is dependent on the temperature and emissivity of the surfaces involved.
An air conditioner is an example of a heat mover. It transfers heat from the inside of a building to the outside, thus cooling the indoor space.
Closed systems exchange energy with their surroundings in the form of heat or work, but do not exchange matter. This means that the total amount of mass in a closed system remains constant over time. Examples of closed systems include sealed containers and insulated thermos flasks.
A Heat Exchanger is a device which is used to transfer heat from one medium to other. A common example is the radiator in an automobile, which transfers the heat from the liquid engine coolant to the air pulled through the radiator by the fan.
Since the question is about heat exchange, I assume it is a man made. The first form of heat exchange is cooking. The first fluid is then water.

It has heat exchange.
You have a $5 bill. You exchange it in for 5 $1 bills.

A refrigerator is an example of a heat mover.
The law of heat exchange, also known as the second law of thermodynamics, states that heat will naturally flow from a higher temperature to a lower temperature until equilibrium is reached. This principle governs the direction in which heat is transferred between objects and systems.
