1. A heat exchange system for a surgical instrument, the heat exchange system comprising:
a valve;
a load;
a load conduit extending between the valve and the load, and configured to deliver fluid from the valve to the load;
an exhaust conduit configured to direct the fluid away from the valve; and
a manifold block, wherein a portion of the exhaust conduit includes a channel in the manifold block, wherein the exhaust conduit extends from the valve, enters and passes through the manifold block, and extends away from the manifold block, and wherein a portion of the load conduit is positioned in the channel so as to thermally transfer heat to a portion of the exhaust conduit.
