The Possibility of Electronic Equipment Cooling
Abstract
Cooling has a large and irreplaceableimportance in electronics and its solution is a part of the
technology design and construction of any real device. Due
to the progressive miniaturization and increasing
performance we can meet cooling more often in consumer
electronic products. In addition to many well-known
conventional methods of cooling there is a possibility to use
a high-capacity heat transport device - heat pipe. A
disadvantage in some applications is the restriction of the
possibility to control the thermal conductivity. The authors
have dealt with so far little explored possibility of control
using an external magnetic field with magnetic fluid as the
heat pipe workload. The system is reversible in terms of
control and uses the unique features of magnetic fluids.
