Title: OIL COOLING DEVICE FOR SERVER AND METHOD FOR DRIVING SAME
Abstract:
The present invention relates to an oil cooling device for a server and a method for driving the same. The oil cooling device for the server comprises: a server tower having a flow path into which insulating cooling oil flows; a heat-absorbing unit for absorbing the heat generated from a heat-generating electronic device within the server tower; a cooling oil tube which is connected to an external cooling device from the flow path of the server tower; a hydraulic pump for circulating the cooling oil of the cooling oil tube; a first temperature sensor which is provided inside the server tower and detects a change in temperature; a storage tank for generating hot water, which enables the cooling oil tube to come in contact with cooling water so as to perform a first cooling step; a heater for enabling the cooling oil tube cooled through the first cooling process to come in contact with the air so as to perform a second cooling process; a second temperature sensor which is provided inside the cooling oil tube and measures the temperature of the cooling oil tube; a residual heat processing unit for performing a third cooling step using a small-sized and low-power cooler provided in the cooling oil tube cooled through the second cooling step; and a control unit for controlling operations of the hydraulic pump and the residual heat processing unit according to measured values from the first and second temperature sensors on the basis of reference temperature data. The present invention can save energy by using the condensation heat generated from the electronic device which generates heat in a large scale server tower for an enterprise so as to enable heat and hot water to be used, and can efficiently cool the server tower through a total of three cooling steps.
