Patent ID: 7004231

Claim:
A fluid exchange system of a natural thermo carrier for heat reclaim is to provide an active heat balance device that gives good heat conduction property in a comparatively stable solid or liquid state thermo carrier in the nature including stratum, geodetic surface, pond, lake or river, comprising: an active regulator comprising an accommodation space; an active heat balance device comprised of a transmission pipeline connected to the accommodation space to cool the accommodation space by absorbing heat from the fluid flowing through the active heat balance device to the active regulator at comparatively higher temperature, or to heat the accommodation space by releasing heat to the fluid flowing through the active heat balance device from the active regulator at comparatively lower temperature; so that while the active regulator is discharging the fluid with temperature differential to an externally passive exchange fluid source, or while the externally passive exchange fluid source inputs the fluid with temperature differential into the active regulator, the active heat balance device absorbs the heat to cool or release the heat to heat the fluid depending on the relative difference of temperature between the fluid passing through and the active heat balance device thus to complete the heat reclaim by heat absorption or heat release in a system configuration including at least one of the following systems: (1) a heat exchange fluid system in direct transmission mode through a one-way flowing passage; (2) a heat exchange fluid system in indirect transmission mode through a one-way flowing passage; (3) a heat exchange fluid system in direct transmission mode through a two-way flowing passage; or (4) a heat exchange fluid system in indirect transmission mode through two one-way flowing passages.
