You can manifold CHESS TEC into curved surfaces and cool / heat gyroid / honeycomb manifolds of copper with conducting surfaces. You can also simply stack them.

You can manifold CHESS TEC into curved surfaces and cool / heat gyroid / honeycomb manifolds of copper with conducting surfaces. You can also simply stack them. The curving reduces efficiency a bit - not much. Regardless there are ways to increase the surfaces area and volume cooled / heated significantly and improve efficiency through different geometries and configurations.
