Heat Exchangers:

Within almost any nuclear, chemical or mechanical system than heat must be transferred from one place to other or from one fluid to another. The Heat exchangers are used to transfer heat from one fluid to another. A general knowledge of the mechanical elements of a heat exchanger is important to understanding how they function and operate.

STATE the two categories of heat exchanger construction.

 Provided with a drawing of a heat exchanger and IDENTIFIES the following internal parts:

a. Tubes                     c. Shell

b. Tube sheet            d. Baffles

EO 1.3 DESCRIBE hot and cold fluid flow in counters flow, parallel flow, and cross flow heat exchangers.

EO 1.4 DIFFERENTIATE among the following categories of heat exchangers:

a. Single-pass versus multi-pass heat exchangers

b. Regenerative versus non-regenerative heat exchangers
