A fluid-convection heat dissipation device 100 includes at least one heat dissipation module 10 forming at least one receiving space and having a plurality of heat radiating fins 12 on an outside surface. An outside surface also functions to receive at least one light emission element 200, such as an LED. At least two baffles 20 are arranged inside the receiving space 11 to divide it into a plurality of convection channels 111, 112, 113, 114, 115, whereby the convection channels collectively define passages that are in communication with each other. Heat dissipation fluid 30 is received in the receiving space of the heat dissipation module to undergo convection as being heated by a heart source spot formed in a junction between the heat dissipation module and the light emission element so as to first flow through the convection channel opposing the junction between the light emission element and the heat dissipation module and further flow along other convection channels to bring thermal energy from the heat source spot to opposite distant ends of the heat dissipation module for dissipation to the surroundings. |
