A temperature-super-conducting component (13) is disposed on an inner surface (11) of the cooling plate (1). The temperature conductor (2) is arranged on the temperature-super-conducting component (13). In addition, a heat-exhausting hole (120) is arranged on an upper side of the cooling plate (1). The centrifugal fan (3) is disposed between the temperature conductor (2) and the heat-exhausting hole (120) while the cooling body (4) is disposed between the fan (3) and the heat-exhausting hole (120). A hot side face (501) of the thermoelectric cooling component (5) closely contacts the cooling body (4) while a cold side face (500) is arranged on the temperature-super-conducting component (13). By quickly conducting the low temperature generated from the thermoelectric cooling component (5) onto the cooling plate (1) through the temperature-super-conducting component (13), a low temperature surface can be uniformly provided to obtain a cooling effect. ## Claims ### Claim 1 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). ### Claim 2 (depends on 1) The cooling rack structure of thermoelectric cooling type according to claim 1, wherein a heightening part (100) is formed by projecting up the supporting surface (10) of the cooling plate (1). ### Claim 3 (depends on 2) The cooling rack structure of thermoelectric cooling type according to claim 2, wherein the heightening part (100) is constituted of a plurality of blocks and formed as a rectangular array. ### Claim 4 (depends on 1) The cooling rack structure of thermoelectric cooling type according to claim 1, wherein the temperature conductor (2) and the cooling body (4) are all made by an aluminum extrusion process and configured as a stacking shape. ### Claim 5 (depends on 1) The cooling rack structure of thermoelectric cooling type according to claim 1, wherein an air hood (32) is further arranged over the centrifugal fan (3) and the cooling body (4). ### Claim 6 (depends on 1) The cooling rack structure of thermoelectric cooling type according to claim 1, wherein the thermoelectric cooling component (5) is a thermoelectric cooling chip. ### Claim 7 (depends on 1) The cooling rack structure of thermoelectric cooling type according to claim 1, wherein the thermoelectric cooling component (5) is further arranged on a substrate (50) which is arranged by being fixed between the cooling plate (1) and the cooling body (4), and on which an opening (51) conforming to a shape of the thermoelectric cooling component (5) is arranged to be provided for the thermoelectric cooling component (5) placed therein.
