Hydra-pressure test was used to check the safety and leakage of the heat exchanger, and then stress test was conducted to get the membrane stress and depression stricken stress to evaluate.

The experiment demonstrates that the load-bearing capacity and compactness of the sand foundation can satisfy the design requirements completely,the compactness of the sand pancakes vary depending on the mixing proportions and the compactness at the edges of the sand pancakes and dents is low.

Review of heat transfer enhancement for dimpled surface;

Influence of dimple space on heat transfer enhancement and pressure loss in a dimpled rectangular channel

The application shows that the optimization can greatly reduce the dimple magnitude and improve the punching quality.
