Patent ID: 8464547

Claim:
A cooling rack structure of thermoelectric cooling type, including: a cooling plate ( 1 ), which has a supporting surface ( 10 ), under which there is an inner surface ( 11 ), a supporting part ( 12 ) being extended from an upper side of the cooling plate ( 1 ) toward the inner surface ( 11 ), a heat-exhausting hole ( 120 ) being arranged on the supporting part ( 12 ); a plurality of heat pipes ( 13 ) attached onto the inner surface ( 11 ) and arranged in a way such that the heat pipes ( 13 ) can be extended and distributed according to the inner surface ( 11 ), which has a first heat pipe ( 130 ) and a second heat pipe ( 131 ); a temperature conductor ( 2 ) which has a plurality of fins ( 20 ) interspaced to each other and configured by extending along a first direction, and which is arranged by closely attaching onto the first heat pipe ( 130 ); a centrifugal fan ( 3 ) which has a sucking inlet ( 30 ) arranged corresponding to the fins ( 20 ) of the temperature conductor ( 2 ) and an exhausting outlet ( 31 ) interspaced correspondingly with the heat-exhausting hole ( 120 ); a cooling body ( 4 ) which has a plurality of cooling fins ( 40 ) interspaced to each other and configured by extending along a second direction substantially perpendicular to the first direction starting from the exhausting outlet ( 31 ) toward the heat-exhausting hole ( 120 ), and which is arranged between the heat-exhausting hole ( 120 ) and the exhausting outlet ( 31 ) to abut the temperature conductor ( 2 ) and the centrifugal fan ( 3 ) at one side and abut the heat-exhausting hole ( 120 ) at the other side; and a thermoelectric cooling component ( 5 ) which has a cold side face ( 500 ) arranged by closely contacting with the second heat pipe ( 131 ) and a hot side face ( 501 ) arranged by closely contacting with the cooling body ( 4 ).
