Fuzhou & Xiamen Port. An electronic heatsink is a device used to dissipate heat generated by electronic components such as transistors, integrated circuits, and power modules. The heatsink is typically made of a thermally conductive material such as aluminum or copper and is designed to transfer heat from the electronic component to the surrounding air or a liquid coolant.The principle behind a heatsink is simple: heat flows from a hot object to a cooler one. In the case of electronic components, the heatsink provides a larger surface area for the heat to transfer to the surrounding air or liquid. This increased surface area allows the heat to dissipate more quickly, preventing the electronic component from overheating and potentially failing.Electronic heatsinks come in a variety of shapes and sizes, depending on the application and the amount of heat that needs to be dissipated. Some heatsinks are designed to be attached directly to the electronic component, while others are mounted on a circuit board or chassis. In addition, some heatsinks are passive, relying on natural convection to dissipate heat, while others are active, using fans or pumps to force air or liquid across the heatsink to increase cooling efficiency.Overall, electronic heatsinks are an essential component in modern electronics, helping to ensure that electronic devices operate reliably and efficiently.

How a Diaphragm Pump Works
The pump is driven by an AC or DC motor
In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber
Has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled through the inlet, through the various valve chamber check valves to the outlet
The volume of flow is determined by several factors including: The number and size of the pump chambers, cam offset, operating pressure, fluid viscosity
