Abstract:
1. A cooling structure for a rackmount-type control device, comprising: an enclosure having a front side and a rear side, each of the front side and the rear side being open; a connection substrate that is provided at a center of the enclosure to divide an interior of the enclosure in a front-to-rear direction; a plurality of control substrates for executing storage device-related control, the plurality of control substrates including front control substrates of a front control substrate group and rear control substrates of a rear control substrate group, the front control substrate group and the rear control substrate group being provided at the front and rear sides of the enclosure respectively; a plurality of power-related devices that includes one or more left power-related devices respectively provided on a left side of the front and rear control substrate groups and one or more right power-related devices respectively provided on a right side of the front and rear control substrate groups; a first cooling passage that has a first upstream side and a first downstream side and cools the front and rear control substrate groups by means of a first cooling air stream, the first cooling passage being configured to direct the first cooling air stream to pass downward through the front control substrate group at the first upstream side, to redirect the first cooling air stream to pass laterally from the first upstream side to the first downstream side, and to redirect the first cooling air stream to pass upward through the rear control substrate group at the first downstream side; a second cooling passage that has a second upstream side and a second downstream side and cools the one or more left power-related devices respectively located on the left side of the front and rear control substrate groups by means of a second cooling air stream, the second cooling passage being configured to direct the second cooling air stream to pass downward through the one or more left power-related devices located on the left side of the front control substrate group at the second upstream side, to redirect the second cooling air stream to pass laterally from the second upstream side to the second downstream side, and to redirect the second cooling air stream to pass upward through the one or more left power-related devices located on the left side of the rear control substrate group at the second downstream side; and a third cooling passage that has a third upstream side and a third downstream side and cools the one or more right power-related devices respectively located on the right side of the front and rear control substrate groups by means of a third cooling air stream, the third cooling passage being configured to direct the third cooling air stream to pass downward through the one or more right power-related devices located on the right side of the front control substrate group at the third upstream side, to redirect the third cooling air stream to pass laterally from the third upstream side to the third downstream side, and to redirect the third cooling air stream to pass upward through the one or more right power-related devices located on the right side of the rear control substrate group at the third downstream side, wherein the first upstream side, the second upstream side and the third upstream side are provided independent of one another and the first downstream side, the second downstream side and the third downstream side are provided in common with one another.
