Abstract
In an electronic component cooling device, a cooler cools an electronic component, a coolant temperature acquisition unit acquires a temperature of a coolant, a coolant flow rate acquisition unit acquires the flow rate of the coolant, a heat loss estimation unit estimates a heat loss from the electronic component, and a loss threshold calculation unit calculates an upper limit threshold of the heat loss from the electronic component based on the coolant temperature and the coolant flow rate. A coolant flow rate control unit controls the flow rate of the coolant and is configured to, in response to an estimated heat loss which is the heat loss from the electronic component that has been estimated by the heat loss estimation unit exceeding the upper limit threshold, increase the flow rate of the coolant circulating through the cooler.
