A bidirectional heat dissipation structure includes a base, a plurality of heat pipes and a heat sink having a plurality of cooling fins. The cooling fins are installed with an interval apart on the heat pipes and stacked onto the base, and each cooling fin includes at least one guide slat. When assembled, a horizontal diversion channel is formed between the cooling fins, and the guide slats form a downward diversion channel. When used, a portion of the wind current dissipates the heat of the heat sink through the horizontal diversion channel, and the other portion of the wind current blows downwardly through the downward diversion channel to dissipate the heat around the electronic device directly, so as to enhance the heat dissipation efficiency significantly.

A heat pipe assembly includes a number of heat pipes and a fixing seat. Each of the heat pipes includes an evaporating section and at least a condensing section. A bottom of the evaporating section of each of the heat pipes is flat and has a flat heat absorbing surface. The evaporating sections of each of the heat pipes are parallel to and adjoin with each other, whereby the flat heat absorbing surfaces of the evaporating sections of the heat pipes being coplanar and adjoining with each other. A top surface of the evaporating section of each of the heat pipes has a top edge. The fixing seat, as a molded one-piece member, combines with the top edge of the evaporating section of each of the heat pipes, whereby the heat absorbing surfaces of the evaporating sections of the heat pipes are coplanar and adjoin with each other.

The present invention relates to a heat sink of a large area, in which a heat-dissipating body is further provided in its limited space. The method for manufacturing a fin includes the steps of providing a fin, cutting the fin to form a foldable piece thereon, folding back the foldable piece to be overlapped on the fin and form an accommodating hole, and punching the folded piece and the fin to form two overlapped through-holes. The fin, the heat-dissipating body and heat pipes are assembled together to obtain the heat sink. Since the fins and the heat-dissipating body dissipate the heat of a heat-generating element simultaneously, the heat-dissipating efficiency of the heat sink can be improved.

A heat-dissipating device (1) including a casing (10), a thermal insulation plate (20), a thermoelectric cooling chip (30), a heat-dissipating body (40), super heat pipes (52), a cooler (53), a first fan (54) and a second fan (60). The thermal insulation plate (20) divides the interior of the casing (10) into a hot air zone (ZH) and a cold air zone (ZC). The thermoelectric cooling chip (30) is disposed on the thermal insulation plate (20) with its hot-end surface (32) facing the hot air zone (ZH). The heat-dissipating body (40) is disposed in the hot air zone (ZH) to contact the hot-end surface (32). The super heat pipes (52) and the cooler (53) thermally contact a cold-end surface (31) of the thermoelectric cooling chip (30). Thus, the cold generated by the cold-end surface (31) can be rapidly and uniformly conducted to other places to form a cold airflow.

The present invention relates to a LED lamp and a heat sink thereof having a wound heat pipe. The LED lamp includes the heat sink, a LED module and a lamp base electrically connected to the LED module. The heat sink includes a heat-conducting base, a heat-dissipating fin set and a wound heat pipe. The heat-dissipating fin set includes a plurality of heat-dissipating fins arranged at the outer periphery of the heat-conducting base. The heat-dissipating fins form an accommodating space. The wound heat pipe includes an evaporating section brought into thermal contact with the heat-conducting base and a condensing section brought into thermal contact with the heat-dissipating fins. The LED module abuts against the heat-conducting base and the evaporating section. By this structure, the heat-conducting path is shortened, the heat-conducting speed is accelerated, and the heat is rapidly and uniformly distributed to the heat-dissipating fins to improve the heat-dissipating efficiency.

The circuit control unit includes a plurality of separated sub-portions. The respective sub-portions of the circuit control unit are distributed uniformly on the circuit board of the LED lamp assembly. Via the uniform arrangement of respective sub-portions of the circuit control unit, the heat within the LED lamp tube can be distributed uniformly, thereby lowering the temperature and facilitating the heat dissipation.

A heat dissipator having heat pipes includes a heat-conducting base, a first heat pipe and a second heat pipe. The heat-conducting base has an accommodating trough. After the first heat pipe is accommodated in the accommodating trough, it is deformed so as to abut against the inner wall face of the accommodating trough. Further, the second heat pipe and the first heat pipe are provided in the same accommodating trough, and the second heat pipe is overlapped vertically on the first heat pipe. As a result, the second heat pipe is deformed so as to abut against the first heat pipe and the interior of the accommodating trough, thereby enhancing the heat-conducting performance of the heat dissipator.

A temperature-super-conducting component (13) is disposed on an inner surface (11) 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.
