Cooling system for ice maker

An ice maker for an appliance comprising:

• an exterior housing;
• an ice tray suspended within the housing and having a plurality of water wells disposed along a transverse axis of the ice tray;
• an electrical drive body rotatably coupled to the ice tray, wherein the drive body is configured to oscillate the ice tray about the transverse axis;
• a thermoelectric device that has a cold side thermally coupled with a bottom surface of the ice tray to freeze water retained in the water wells and a hot side opposing the cold side;
• a heat sink thermally coupled with the hot side of the thermoelectric device that includes a plurality of metal fins extending from the hot side;
• and
• a shroud member coupled with the ice tray and spanning beneath the heat sink, wherein the shroud member abuts the housing about a periphery of the ice tray to define a first air chamber above the ice tray and a second air chamber below the ice tray, and wherein the shroud is configured to restrict cold air flow in the second chamber from entering the first air chamber.

• a heat sink thermally coupled with the hot side of the thermoelectric device;
• a barrier extending from the housing and abutting longitudinal edge portions of the ice tray to define a first air chamber above the ice tray and a second air chamber below the ice tray;
• an intake duct member coupled with the housing proximate the second air chamber, wherein the intake duct member is configured to dispense a cold air flow over the heat sink, and wherein the first air chamber includes warmer air than the second air chamber to form at least one clear ice piece in the ice tray.
