Abstract: A method for assembling a heat-dissipating module includes a step of mechanically pressing one time or multiple times a heat pipe into a trough of a metallic base, whereby at least one end of the heat pipe can be pressed into the trough of the metallic base and thus firmly combined with the metallic base. In this way, the time and the cost for assembly are reduced, and the yield is increased.

Abstract: A heat-dissipation structure and a manufacturing method thereof are disclosed. The heat-dissipation structure includes a base having a main body and a tube. The tube has an inlet, an outlet, and a tube body; and the tube body is correspondingly embedded in the main body to serve as a flow passage while the inlet and the outlet are exposed from the main body. The heat-dissipation structure can be manufactured by pour molding or insert molding to embed the tube in the base for serving as a flow passage. With the manufacturing method, the heat-dissipation structure can be formed at reduced material, labor and time costs without the risk of water leakage.

Abstract: A motor water-cooling structure and a manufacturing method thereof are disclosed. The motor water-cooling structure includes a motor case having a wall portion and a tube. The tube is embedded in the wall portion to serve as a flow passage. To manufacture the motor water-cooling structure, the tube is positioned in a mold cavity of a mold, and the motor case is formed in the mold by pour molding to embed the tube therein, so that the motor case and the tube form an integral body. With the manufacturing method, the motor water-cooling structure can be formed with reduced material, labor and time to save the manufacturing costs, and the risk of water leakage can be avoided.

Abstract: A water-cooling structure for electric motor includes a motor main body, a heat-dissipation base, and a vortex-forming section. The motor main body is externally fitted around the heat-dissipation base. The heat-dissipation base is provided around an outer circumferential surface with at least one main flow passage. The vortex-forming section is provided in the main flow passage to create vortex effect on a type of cooling liquid flowing in the main flow passage, so as to enable an increased heat transfer efficiency of the water-cooling structure.

Abstract: A heat exchanger structure with flow divider includes a heat-conductive main body provided with a flow passage having at least one inner turn and one outer turn, and at least one flow divider located near and downstream the inner turn, such that a cooling liquid in the flow passage flowing through the inner and the outer turn to reach at the flow divider is divided by the flow divider into two smaller flows. Therefore, the cooling liquid in the flow passage has reduced pressure drop and it is not necessary to increase the operating power of a pump that delivers the cooling liquid into the flow passage.

Abstract: A flow passage structure for water-cooling device includes a heat-conductive main body provided with at least one flow passage, an inlet, and an outlet; and at least one vortex-forming section. The flow passage is provided in the heat-conductive main body and has a type of cooling liquid contained therein. The flow passage includes a channel portion and a top portion integrally connected to one another to ensure a leak-free flow passage. The at least one vortex-forming section is provided on one of the channel portion and the top portion for the cooling liquid flowing therethrough to form separated vortexes, so as to enable largely increased flow field turbulence in the flow passage and accordingly upgraded heat transfer performance of the cooling liquid.
