Abstract
An apparatus and method for extinguishing a thermal runaway in an electronic component is provided. The apparatus comprises a heatsink affixed to the electronic component, a reservoir containing coolant, and one or more Phase Change Material (PCM) plugs blocking coolant contained in the reservoir, where the PCM plugs, in response to the electronic component being at an approximate temperature of the Phase Change Temperature (PCT) of the PCM plugs, melt, thereby causing coolant to being dispersed onto the electronic component. The method comprises, in response to the electronic component reaching a temperature indicative of a thermal runaway event occurring in the electronic component, melting one or more phase change material (PCM) plugs, wherein the PCM plugs block coolant from draining out of a reservoir. In response to the PCM plugs melting, releasing the coolant from the reservoir onto the electronic component to extinguish the thermal runaway event.
