Water-cooled heat dissipating device

A water-cooled heat dissipating device for conveying a working fluid, comprising:

• a base (1), comprising a division plate (11), a chamber (12), a flow guiding pole (13) vertically connected to the division plate (11) and projecting from the chamber (12), and both a water inlet (14) and a water outlet (15), which connect to a side of the base (1), the division plate (11) dividing the chamber (12) into a catchment portion (16) and a heat exchanging portion (17), and the flow guiding pole (13) communicating with both the catchment portion and the heat exchanging portion (17);
• a passive impeller (3) received in the chamber (12) and radially driven to rotate by the working fluid;
• a cold plate (4), arranged correspondingly to the heat exchanging portion (17), and fastened to the base (1);
• and
• a top cover (5) assembled on the base (1), a transparent cover plate (6) disposed between the base (1) and the top cover (5) and a lighting module (7) disposed between the top cover (5) and the transparent cover plate (6), wherein the top cover (6) is formed with a concave opening (51) for exposing the transparent cover plate (6),
• wherein the lighting module (7) comprises an LED (light emitting diode) strip light (71), a connector (72) and a wire set (73) connected between the LED strip light (71) and the connector (72), and both the connector (72) and part of the wire set (73) pass through the base (1).
