In addition, the ice tray main body 10 is made of one or more of aluminum alloy, zinc alloy, and magnesium alloy. The aluminum alloy, the zinc alloy and the magnesium alloy have the characteristics of low cost and good corrosion resistance, do not need to increase an anti-corrosion process, and reduce the production and manufacturing cost.

In this embodiment, the cover plate is provided with a liquid inlet 21 and a liquid outlet 22, the liquid inlet 21 and the liquid outlet 22 are both communicated with the condensation channel 13, and the condensation channel 13 is distributed on the ice tray main body 10 in a curved shape.

It can be understood that the condensing channel 13 needs to circulate the medium for heat exchange to perform heat exchange, such as cooling liquid, which can enter from the liquid inlet 21 and then flow out from the liquid outlet 22 after heat exchange, thereby completing heat exchange.

The design of the ribs can be varied in the case of heat exchange. Referring to fig. 4, the rib 12 may be a conventional pipe design, and the liquid inlet 21 and the liquid outlet 22 are respectively designed at two ends of the cover plate 20, so that the cooling liquid can flow from the liquid inlet 21 at one side, along the condensation channel 13, and then flow out from the liquid outlet 22.
