Natural & Forced Convection Experiment Bench

Natural & Forced Convection Experiment Bench

Product Overview

1.1 Overview

The ZT0006 Natural and Forced Convection Experiment Bench is designed to help students learn and understand convective heat transfer—one of the three fundamental modes of heat transfer in thermodynamics.

• Natural Convection: Occurs due to density differences in fluids caused by uneven temperature distribution.

• Forced Convection: Driven by external devices such as fans or pumps.

The ZT0006 provides a compact, plug-and-play teaching solution for both principles, featuring:

• A vertical pipe with detachable heating elements

• Multiple temperature sensors and anemometer

• Waterproof electrical junction box and power control box

• Interchangeable heat exchangers: tube bundle, cylindrical, and plate

This modular design allows students to conduct multiple experiments while observing and analyzing real-time data.

1.2 Key Features

1. Compact & User-Friendly – Small footprint, plug-and-play design for easy use in teaching labs.

2. Safe & Durable – Built with high-quality materials and protective coatings for long service life.

3. High Compatibility – Flexible software support and data communication options.
