AI Technical Summary

Technical Problem

Existing battery cell arrangements in housings face challenges due to manufacturing and assembly tolerances, leading to difficulties in precise positioning and effective heat transfer, exacerbated by high-viscosity potting compounds used for thermal conductivity.

Method used

A tolerance-compensating thermal conductivity element with a base body and spring elements, embedded in a low-viscosity potting compound, compensates for manufacturing and assembly tolerances, ensuring secure positioning and efficient heat transfer between components.

Benefits of technology

The solution provides reliable positioning and enhanced heat dissipation with reduced manufacturing costs, using a cost-effective, easy-to-apply design that maintains thermal conductivity and electrical insulation.

Abstract

Arrangement with a tolerance-compensating heat-conducting element (30) comprising a heat-conducting base body (32) with at least one resilient element (361, 362, 363, 364, 365) and a potting compound (40), wherein the base body (32) is arranged in a gap (28) between a first component and a second component, wherein the base body (32) bears against the first component with a first side and bears against the second component with the resilient element (361, 362, 363, 364, 365) with a pre-tensioned bearing on the second component opposite the first side, and wherein the base body (32) is almost completely embedded in the potting compound (40).
