Define a heat exchanger
WebHeat is sometimes called a process quantity, because it is defined in the context of a process by which energy can be transferred.We don't talk about a cup of coffee … WebHeat exchangers are devices that transfer thermal energy from one fluid to another without mixing the two fluids. The fluids are usually separated by a solid wall (with high thermal conductivity) to prevent mixing, or they may be in direct contact. Heat exchangers are typically classified according to flow arrangement and type of construction.

The fluids can be single or two phase and, depending on the exchanger type, may be separated or in direct contact.
A simple heat exchange might be thought of as two straight pipes with fluid flow, which are thermally connected. Let the pipes be of equal length L, carrying fluids with heat capacity (energy per unit mass per unit change in temperature) and let the mass flow rate of the fluids through the pipes, both in the same direction, be (mass per unit time), where the subscript i applies to pipe 1 or pipe 2. WebA heat exchanger is a vessel or stage which moves heat between one fluid and another. In cooling towers, the cooling water passes through a refrigerant-water heat exchanger to achieve thermal transfer. A heat exchanger is any device which effects the transfer of thermal energy from one fluid to another.
