Abstract
An object is to provide a semiconductor cooling device which optimally keeps the mixing amount of microbubbles in the refrigerant and prevents the reduction of the cooling effect of the semiconductor module. The semiconductor cooling device includes a refrigerant circulation path through which refrigerant circulates, a heat exchanger provided on the refrigerant circulation path on which a semiconductor module is installable and configured to exchange heat between the refrigerant and the semiconductor module, a microbubble generator provided on the refrigerant circulation path, and configured to generate microbubbles in the refrigerant, a controller configured to control the microbubble generator, and a refrigerant sensor configured to measure a temperature, a flow rate, a flow velocity, or a pressure of the refrigerant circulating in the refrigerant circulation path. The controller is configured to control the microbubble generator based on a measurement result measured by the refrigerant sensor to control the generation amount of microbubbles.
