Disclosed is a device that relates to dust build-up on a heatsink inside of a computer system or kiosk and the removal of the dust particulates from the heatsink by an external vacuum system interfacing with an internal heatsink wiper apparatus.

Heatsink Particulate Removal Device

The invention describes an external vacuum actuation of an internal wiper system positioned in-between the heatsink to be cleaned and a system fan (See Figure 1). During normal use of the computer this internal wiper system would be in the retracted position whereas the airflow is free to flow from the fan to the heatsink. Using an internal thermal sensor coupled to the device upon which the heatsink sits a set of red/green LEDs would denote when the system needs to be cleaned based on the sensor signal
of a hot device. The user simply puts the tip of the vacuum into the side of the system, which causes the internal wiper to be pushed into position mechanically. The tip of the internal wiper being fitted with vacuum ports and brushes dislodge the dust build-up and allow the vacuum to pick it up. The internal wiper moves in and out of the path of the system fan and heat sink. When the vacuum tip is retracted the wiper returns back to a docking position via a spring member attached to the tip of the wiper and anchored to the computer chassis wall. The wiper device temporality blocks off the fan and dislodges the dust from the leading edges of the heat sink. The dust particulates then break free and the vacuum collects the dust and debris collected on the leading edges of the heat sink.
