Abstract: A filling material of power transmission bus bar, composed mainly of a silicone and an inorganic material, wherein weight ratio of said silicone and said inorganic material is between 1:0.1 and 1:9. As such, the resilience of the silicone can increase the buffering capability of said power transmission bus bar in facing pressure of strong winds; also stiffness of said inorganic material can increase the stability of said power transmission bus bar in a same situation. Said filling material of power transmission bus bar is able to protect metallic conduction element of said power transmission bus bar from getting in touch with moisture and dust, that may reduce its efficiency in transmitting power.

Abstract: A heat exchanger radiating fin structure and a heat exchanger thereof. The radiating fin includes a main body and at least one rib. The main body has a first plane face and at least one lateral side. Multiple depressions are formed on the first plane face. The rib is disposed on a portion of the first plane face, which portion is free from any of the depressions. The rib obliquely extends in a direction neither normal nor parallel to any lateral side of the first plane face. The heat exchanger includes a radiating fin assembly composed of multiple piled up radiating fins. Each two adjacent radiating fins define therebetween a flow way having at least one inlet and at least one outlet. With the depressions and the rib, the structural strength of the radiating fin is increased and the heat exchange performance of the heat exchanger is enhanced.

Abstract: A heat exchanger including a first heat sink, a second heat sink and a water-cooling unit. The first heat sink has a first contact section and multiple radiating fins. At least one cooling chip is attached to the first contact section. At least one first fan is disposed on the radiating fins. The second heat sink has multiple radiating fins and a second contact section. A second fan is positioned on the radiating fins and connected thereto. The second contact section is attached to a face of the cooling chip opposite to the first heat sink. The water-cooling unit has a water tank section and a pipe section having a first end and a second end, which are connected to the water tank section. The pipe section is inlaid in the first contact section and the water tank section is disposed on the radiating fins of the second heat sink.

Abstract: A heat exchanger structure includes a pipe and a flow-guiding element. The pipe internally defines a chamber, in which the flow-guiding element is disposed. The flow-guiding element includes a helical main body and a plurality of turbulence promoters radially outward extended from two opposite lateral sides of the helical main body. The turbulence promoters are independently arranged on the helical main body with free ends of the turbulence promoters contacting with an inner wall surface of the chamber, so that a fin cooling effect is produced. The turbulence promoters and the helical main body together define at least one flow-guiding section. With the helically distributed turbulence promoters of the flow-guiding element, the heat transfer ability and the thermal performance factor of both laminar and turbulent flows in the pipe can be increased to provide excellent heat transfer effect.

Abstract: A thermal module includes at least one heat dissipating element, at least one cooling chip, and a heat radiating unit. The cooling chip has a cold end in contact with one side of the heat dissipating element and a hot end in contact with the heat radiating unit. With the cooling chip in direct contact with the heat radiating unit and the heat dissipating element, the heat dissipating element can be directly cooled by the cooling chip, and the thermal module can have a simplified structure to occupy a reduced room while providing enhanced heat dissipating efficiency and accordingly upgraded heat-dissipating effect.
