Abstract
Various embodiments disclosed herein describe thermoelectric cooling modules. The thermoelectric cooling modules may include a first substrate positioned over a second substrate in a vertical stacking direction, and may include a thermoelectric connector that thermally connects the first and second substrates. The thermoelectric connector may be configured to transfer heat laterally relative to the vertical stacking direction to provide more efficient heat transfer between the first substrate and the second substrate.
