GLOSSARY

Thermosyphon : a method of passive heat exchanger that are based on natural convection to flow the liquid of the system without using additional system such as pump.

Flowcharts : a type of diagram which represent the process of some system or algorithm, which are represents by boxes for the step and arrows for the order.

Conduction : the process of electricity or heat is directly transmitted through a substance when there is a difference of temperature or electrical potential without a movement of the material.

Radiation : an emitted or transmitted energy in the forms of waves or particles through a space or material medium.

Convection : a process of liquid or gas that are depends on the different amount of energy in terms of particles or less heat energy.

Modular : terms of which a systems component may be separated or recombined by using some kind of system or joint method.

Efficiency : the state or quality of being efficient in terms of the ratio of the useful work performed by a machine or in a process to the total energy expended or heat taken in.
