摘要

#CMT# #/CMT# The arrangement has a semiconductor matrix (4) provided between a high temperature-side base plate (2) and a low temperature-side base plate (3), where the base plates are provided with two-dimensional physical dimensions. The base plates are positively connected with hot and cold upper surfaces respectively, by welding or soldering. One of the base plates has a dimension that is 3 millimeter longer than the matrix. An insulating material is arranged between a thermoelectric generator (1) and the hot upper surface. #CMT#USE : #/CMT# Arrangement for a thermoelectric generator that converts waste heat of an internal combustion engine of a vehicle into an electrical current. #CMT#ADVANTAGE : #/CMT# The base plates are positively connected with the hot and cold upper surfaces respectively, by welding or soldering, and the insulating material is arranged between the arrangement and the hot upper surface, thus preventing overheating of the semiconductor matrix, during connection of the semiconductor matrix to the hot upper surface. The arrangement prevents thermal deterioration of the semiconductor matrix and heat flux at a connection point between the semiconductor matrix and the hot upper surface. The arrangement improves heat transfer characteristics and efficiency of the thermoelectric generator. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a three-dimensional schematic view of an arrangement for a thermoelectric generator.
