Overall Didactic Concept

The transfer of heat, with its diff erent

forms of transfer, is the foundation

of thermodynamics. The controlled

transfer of heat takes place in a heat

exchanger. Depending on the require-

ments, diff erent heat exchangers are

used in practice in order to enable an

effi cient transfer of heat.

Students often fi nd the notoriously

diffi cult and dry content of applied

thermodynamics hard to understand.

The WL 110 series helps to methodi-

cally link and apply learnt theory with

real world, practical components.

We speak from experience and, with

our educationally benefi cial overall

concept, we want to help you to teach

this complex subject.

Linking theory and practice

provides the foundation

for understanding complex

technical relationships.

Real Technical

Components

The modular WL 110 series of equipment off ers exten-

sive experiments on diff erent heat exchangers. Diff erent

models of heat exchangers are investigated and com-

pared with each other.

In order to visualise the thermal processes in the heat

exchanger, our innovative and powerful software is an

integral part of the training system. The software enables

a unique form of representation and helps students to

conduct and evaluate experiments. The software deliber-

ately helps create a link between practice and theory.

To complete our overall didactic concept, WL 110

includes multimedia training software which supports

students in the preparation and follow-up of experiments.

The training software enables independent learning of the

theoretical fundamentals and, through explanatory texts,

illustrations and moving images, contributes to under-

standing of the topic.

Tubular heat exchangers are the simplest type of heat

exchanger design. They are preferred when heat is being

transferred at high pressure diff erences or between highly

viscous media. One advantage is that fl ow through the

pipe space is even and free of fl ow dead zones.

The hot water is fed through the core tube (inner) and the

cold water fed through the jacket tube (outer). In doing so,

the hot water continuously emits some of its thermal energy

to the cold water.

Two additional temperature sensors are located on the tubular

heat exchanger to measure the temperature after one half of

the transfer section.

Plate heat exchangers are mainly characterised by their

compact structural shape, in which the entire medium is used

for heat transfer. One advantage is the low space requirement,

relative to the heat transfer area.

The plate heat exchanger consists of several profi led plates.

Connecting the plates to each other results in two hermetically

separated tube channels. A cold tube channel and a hot tube

channel alternate in the arrangement. The narrow tube channels

produce turbulent fl ow.

Shell and tube heat exchangers are characterised by the large

heat transfer area and the compact structural shape.

The shell and tube heat exchanger consists of seven core

tubes, surrounded by a transparent jacket tube. The hot water

fl ows through the core tubes and the cold water fl ows through

the jacket tube. In doing so, the hot water emits some of its

thermal energy to the cold water. Using baffl e plates, the fl ow

in the inside of the shell is diverted in order to produce stronger

turbulence and more intensive convective heat transfer.

The media fl ow continuously in cross fl ow.

Many engineering processes use simple stirrer tanks. These are

often fi tted with a double jacket or a coiled tube for cooling or

heating. Stirring machines are used for better mixing of the tank

contents and for an even temperature distribution.

The jacketed vessel with stirrer and coil consists of a tank

surrounded by a jacket. In the tank is a coiled tube. In the heating

with jacket operating mode, the hot water fl ows through the

jacket and emits some of its thermal energy to the cold water in

the tank. In the heating with coiled tube operating mode, the hot

water fl ows through the coiled tube and heats the cold water in

the tank. A stirring machine can be used in all operating modes.
