Client comments on the Mechanical Analysis
This well-performed mechanical analysis focuses on thermodynamics of ice maker, which is critical to its functionality. Here are few comments to the analysis:
- In your bill of material, the material of ice tray is listed as unknown metal, but this analysis seems to assume the material as aluminum without further explanation. Please check the consistency in your document.
- Please list the thermal properties of water and aluminum you used in the FEA.
- Currently we can not tell how the boundary conditions and initial conditions are applied in your FEA model. Please indicate them clearly in Figure 1 by using textboxes.
- It is worthy a note that converting 1 gram of ice at 0 °C into 1 gram of water at 0 °C requires additional 333 J of heat. Please make sure this is taken into account and added into your assumptions.
- Please give more conclusions upon your analysis results. For example, can the simulated 5.5 hours represent the practice freezing time? How do you apply the single-cube analysis results to the whole tray?
