Embodiment Construction

[0040] exist Figure 1A The vehicle 10 is schematically shown in . Vehicle 10 includes vehicle systems 12 that need to be heated or cooled. In one example, the vehicle system 12 includes a battery 14 , such as a lithium-ion battery used for vehicle propulsion, that generates a significant amount of heat. Such cells must be cooled during operation, otherwise cell efficiency and / or integrity (soundness) may be reduced.

[0041] Cooling system 18 is arranged in a stack between battery 14 and DC / DC converter 16 to remove heat from battery 14 to cool vehicle system 12 . A DC / DC converter 16 provides an electrical interface between the battery 14 and the vehicle electronics. The cooling system 18 includes a thermoelectric module assembly 20 mounted to a cold plate assembly 22 that communicates with a cooling circuit 24 . A cooling fluid such as glycol is circulated by a pump 31 within the cooling circuit 24 . Heat is rejected via the cold plate assembly 22 to the coolant through...

Abstract

A thermoelectric module assembly for thermally conditioning a component includes first and second members that are spaced apart from one another and are configured to respectively provide cold and hotsides. An insulator plate is arranged between the first and second members. A thermoelectric device is arranged within the insulator plate and is operatively engaged with the first and second members. A fastening element secures the first and second members to one another about the insulator plate in an assembled condition. A thermal insulator is provided in one of the first and the second members and is configured to receive the fastening element.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 62 / 173,472, filed June 10, 2015, which is incorporated herein by reference. technical field [0003] The present disclosure relates to thermoelectric modules for cooling vehicle components such as batteries. In particular, the present disclosure relates to thermal isolation features within thermoelectric modules for improving heat transfer efficiency. Background technique [0004] Lithium-ion batteries are used in passenger and other types of vehicles to power an electric motor that provides propulsion to the vehicle. Such batteries generate a large amount of heat, so that the battery must be cooled to prevent performance degradation. [0005] One type of vehicle battery cooling arrangement has been proposed that includes a thermoelectric module disposed below the battery and adjacent to a cold plate assembly. The thermoelectric module include...
