Abstract
A cooling apparatus includes an immersion-tank configured to store a refrigerant, a refrigerant suction port formed at a lower portion of the immersion-tank, the refrigerant suction port being configured to suck the refrigerant from an outside of the immersion-tank into an inside of the immersion-tank, an electronic device immersed in the refrigerant, the electronic device including, a first heat-generation portion, a second heat-generation portion having a heat-generation amount smaller than a heat-generation amount of the first heat-generation portion, and a refrigerant inlet positioned below the first heat-generation portion and the second heat-generation portion and being open downward, and a block positioned below the first heat-generation portion and the second heat-generation portion, the block including a through-hole through which a region positioned below the first heat-generation portion in the refrigerant inlet is open, and a closing portion that closes a region positioned below the second heat-generation portion in the refrigerant inlet.
