DEVELOPMENT AND EVALUATION OF HEAT PUMP SYSTEMS UTILIZING CAE TOOLS

Abstract

The Coolant pump assembly is a system to move heat around the engine. The main purpose of
the assembly is to carry away the intense heat generated by the combustion in the engines and other
applications include heating parts of the engine for cold weather. The engine runs best at a fairly high
temperature. When the engine is cold, components wear out faster, and the engine is less efficient and
emits more pollution. So another important job of the cooling system is to allow the engine to heat up as
quickly as possible, and then to keep the engine at a constant temperature. The heat pump assembly is
modeled using Catia and the analysis is carried out in Ansys. The heat pump system is subjected to
different fluctuating temperatures from 260oC to room temperature. So, detailed thermal and structural
analysis was carried out for designing the system and studied different modifications for proposing the
optimum design with reduced deformations and stresses due to thermal loads.
