Patent ID: 8305178

Claim:
A heat exchange device installed between an electrical equipment and a superficial temperature maintaining member such as superficial ground, lake, pool or river and equipped with a primary fluid loop and a secondary fluid loop, so that the heat generated by the electrical equipment is transmitted by the primary side fluid of the heat exchange device, wherein the heat exchange device is installed at one side of the electric transformer housing and the fluid in the secondary side of the heat exchange device passes through a heat equalizer installed in the superficial temperature maintaining member so as to dissipate heat to the superficial temperature maintaining member, comprising: electric transformer ( 101 ): which is a voltage transforming device having coil set and iron core, and installed in a housing ( 100 ), wherein the housing ( 100 ) is provided with an insulation cooling fluid ( 103 ) for dissipating the heat generated by the electric transformer ( 101 ); heat exchange device ( 404 ): which is a container structure allowing cooling fluid ( 411 ) to pass through, and installed at the exterior of the housing ( 100 ) of electric transformer ( 101 ) for jointly providing a heat exchange function, an inside of the container structure containing vertically extending fluid pipelines ( 402 ) installed at one side of exterior of the housing ( 100 ) of the electric transformer ( 101 ), the insulation cooling fluid ( 103 ) in the housing ( 100 ) of the electric transformer ( 101 ) being circulated through fluid pipelines ( 402 ) such that the fluid pipelines ( 402 ) transmit thermal energy jointly with the housing ( 100 ) to cooling fluid ( 411 ), and enables the cooling fluid ( 411 ) pumped by the fluid pump ( 406 ) to pass through the heat dissipation device ( 409 ) installed in the natural heat storing member ( 108 ) and thereby form a circulation fluid for transmitting thermal energy; heat dissipation device ( 409 ): which is a heat dissipation container structure made of a high heat conductive material and allowing the cooling fluid ( 411 ) to pass through, and installed in a superficial heat storing member ( 108 ) constituted by land, lake or river; fluid pump ( 406 ): constituted by a fluid pump driven by a mechanical or electric motor.
