Patent ID: 8113192

Claim:
An evacuated tubular solar collector with an eccentric type manifold flange, comprising: an evacuated tubular solar collector positioned vertically to a ground surface; a manifold being installed at an upper position of the evacuated tubular solar collector and including a protruding holder and a number of heat dissipation holes which are arranged on an internal center of the manifold and spaced apart from one another, the heat dissipation holes receiving a condenser of a heat pipe; and eccentric end caps attached to both sides of the manifold, each of the eccentric end caps including a fluid path and a baffle, wherein the fluid path is formed at an uppermost position of each of the eccentric end caps highest from the ground surface; wherein the baffle of each of the eccentric end caps comprises a number of ventilators and is attached along a vertical line of each of the eccentric end caps at an exit of the fluid path through which a fluid flows into, so that, for a uniform flow, the fluid uniformly contacts the heat dissipation holes positioned inside the manifold; further, the baffle attached to each of the eccentric end caps is sloped by a predetermined slope angle α with respect to an inside surface of the eccentric end caps, so that the fluid flows into a lower part of the manifold; and further, the baffle attached to the inside of each of the eccentric end caps attached to both sides of the manifold, in which the baffle is attached to the inside of the eccentric end caps through which the fluid as a heat medium flows into, the inside of the eccentric end caps through which the fluid is discharged, or both sides of the eccentric end caps; and wherein the protruding holder is formed inside the manifold at which the baffle is attached, so that the baffle is held using a fixing unit.
