• wherein the liquid coolant circulates through a passageway formed by the U-shaped conduit.

A heat exchanging device used for cooling a power supply having a plurality of heat-producing elements, comprising:

• a heat sink on which the heat-producing elements are mounted and which has a passageway through which a liquid coolant for cooling the power supply, passes, provided inside thereof;
• and
• a conduit fitted into opposite ends of the passageway, forming an inlet port and an outlet port through which a liquid coolant for cooling the power supply, comes in and goes out,
• wherein the liquid coolant circulates through the passageway.

A heat exchanging device used for cooling a power supply having a plurality of heat-producing elements, comprising:

• a hermetic container installed to surround the power supply and contains an insulating oil which is in direct contact with the power supply;
• and
• an inlet port and an outlet port formed at the side walls of the hermetic container so that the insulating oil comes in and goes out therethrough,
• wherein the insulating oil functions as the liquid coolant for cooling the power supply,

A heat exchanging device used for cooling a power supply having a plurality of heat-producing elements, comprising:

• a hermetic container installed to surround the power supply and contains an insulating oil which is in direct contact with the power supply;
• a cooling plate heat-exchangeably contacting with the outer top surface of the hermetic container and having a U-shaped channel formed at one side being securely in contact with the hermetic container;
• and
• a U-shaped conduit fitted into the U-shaped channel, having a flat bottom so as to be securely in contact with the outer top surface of the hermetic container and having opposite ends forming an inlet port and an outlet port,
• wherein the liquid coolant circulates by a passageway formed by the U-shaped conduit.

A heat exchanging device used for cooling a hard drive of a computer, comprising:

• a cooling plate heat-exchangeably contacting with the bottom surface of the hard drive and having a pair of channels spaced apart from one side being securely in contact with the hard drive;
• and
• a U-shaped conduit fitted into the pair of channels, having a flat top surface so as to be securely in contact with the bottom surface of the hard drive and having opposite ends forming the inlet port and the outlet port,
