Abstract: A progressive stopper for a pressure sensing element is able to redistribute and reduce the stress of a diaphragm exposed to high pressure via multi-step contacts, such as at least dual contacts, where the diaphragm (designed for detecting pressure within a defined pressure range) is enabled to withstand much higher pressures above of the defined pressure range, such that the progressive stopper prevents catastrophic failure of the diaphragm. The progressive stopper is created to redistribute and reduce stress on the diaphragm significantly and effectively. The progressive stopper does not limit the output of the pressure sensing element such that the pressure sensing element is able to maintain the output voltage above the maximum output voltage of the defined pressure range when the diaphragm is exposed to high pressures with reduced stresses and strains.

Abstract: A heat dissipation structure for a casting block assembly, which includes a tube extending through a casting block, and the tube has at least one turbulence generating device to promote turbulence inside the tube and reduce boundary layer thickness, and therefore increase the heat transfer coefficient. The turbulence generating device is one or more ribs or dimples integrally formed as part of the tube, before forming the casting block around a portion of the tube. The ribs or dimples promote turbulence to reduce boundary layer thickness, and therefore increase the heat transfer coefficient. The turbulence generating devices promote higher turbulence intensity, a thinner boundary layer thickness, increased heat transfer coefficient, and a stronger bond between the tube and the casting block. The tube may have an elliptical cross-section, which allows for increased spacing between various portions of the tube while maintaining the same cross-sectional flow area, enhancing heat transfer.
