Thermal management

Definition

Thermal management refers to the process of controlling the temperature of a system to ensure optimal performance and reliability. In underwater robotics, effective thermal management is essential to maintain the functionality of electronic components and batteries, preventing overheating that can lead to failure. This involves both passive and active cooling techniques, which help dissipate heat generated during operation and keep the system within acceptable temperature ranges.
