RELATED APPLICATIONS

This US application claims the benefit of priority to Taiwan application no. 112125373, filed on Jul. 7, 2023, of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to heat-transfer components and assemblies, and more particularly, but not limited to, cooling system block assemblies.

BACKGROUND OF THE INVENTION

With increasing processing speed and performance of electronic devices, the amount of heat generated during operation of an electronic device has increased. The heat generation increases the temperature of the electronic device and, if the heat cannot be dissipated effectively, the reliability and performance of the electronic device is reduced. To prevent overheating of an electronic device, cooling systems such as air-cooling systems and liquid cooling systems are used to efficiently dissipate the heat generated by the electronic device and, thereby ensure the standard operation of the electronic device.

In the case of air-cooling systems for packaged integrated circuits, heat is dissipated from an upper surface of a packaged integrated circuit via upper surface adherence of a heatsink or cooling system block to the packaged integrated circuit. The heatsink or cooling system block is commonly mounted to the packaged integrated circuits via attachment members such as screws and push pins. Thermal pads (also called thermally conductive pad or thermal interface pad) and thermal paste (also called thermal compound, thermal grease, thermal interface material (TIM), heat sink compound, heat sink paste or CPU grease) may be used to enhance adherence and aid in heat conduction. The thermal pads and thermal paste fill in air gaps caused by imperfections of the adhered surfaces allowing for effective heat transfer.

Often, when mounting, positioning members, such as the screws and the push pins and other separate positioning members, are fixed to the heatsink or cooling system block and/or a circuit board for vertical alignment of the attachment members before fixing. Thus, prior to fixing, the heatsink or cooling system block is prevented from moving horizontally via the positioning members. However, following operation of the electronic devices, an adhesive force between the heatsink or cooling system block and packaged integrated circuit increases. Thus, when the heatsink or cooling system block is unmounted from the packaged integrated circuits, difficulty in separating the adhered surfaces from each other increases. Separating the heatsink or cooling system block from the packaged integrated circuit is further exacerbated as the heatsink or cooling system block is prevented from moving horizontally. Due to the increased adhesive force and vertical pulling of the heatsink or cooling system block, the packaged integrated circuit may be damaged or become inoperable. Separately unfixing the positioning members from the heatsink or cooling system block and/or a circuit board makes unmounting inconvenient, time-consuming, and inefficient, and lost parts of and damage to the positioning members more likely.
