Lesson notes

Learning Objectives

Indicator: 2.1.1.LI.2 - Describe the construction and operation of the thermosyphon and pump assisted water-cooling systems

By the end of the lesson, learners can:

  1. Explain the purpose of the engine cooling system and state why excessive engine heat must be controlled.
  2. Identify and label the main components of a water-cooling system from a chart or real engine.
  3. Describe, in order, how coolant circulates through a thermosyphon water-cooling system.
  4. Describe, in order, how coolant circulates through a pump assisted water-cooling system.
  5. Compare the thermosyphon and pump assisted systems, stating the advantages of the pump assisted system.

Exemplars (from the NaCCA curriculum) 

Problem based Learning: Learners brainstorm in groups with views tolerated from others, to discuss the exact purpose of cooling system, and also examine the layout of thermosyphon and pump assisted water-cooling systems on a motor vehicle and present a report for discussions.
Experiential learning: Learners visit a local repair or school workshop to observe the working principle of thermosyphon and pump assisted water cooled engines
