1. High heat transfer efficiency: sinusoidal flow of fluid outside the plate, low-speed turbulent flow of fluid inside the plate with small hydraulic radius. Pillow shaped design creates conditions for high heat transfer coefficient.

2. Laser welding, reliable quality: two metal plates are stacked, through full-automatic fiber laser penetration welding, and then high-pressure bulging forming. As a high-precision welding method, laser welding has good welding quality, small deformation and minimal damage to materials.

3. Small resistance and low pressure: the fluid outside the plate flows in a sinusoidal state with low resistance; With small hydraulic radius, the fluid in the plate can also form turbulent flow at low speed, and the corresponding resistance is relatively low.

4. Smooth surface, easy to clean: the natural surface formed by swelling is not easy to accumulate dust and dirt, so it is easy to clean.

5. Various shapes and customization: the plate can be divided into single-sided pillow flower and double-sided pillow flower. The plates can be processed into various shapes: plate tube type, disc type, ring type, tube type, spiral type, cone type and so on.
