Condensing device and thermal module using same

A thermal module, comprising:

• a condensing device consisting of a hollow main body;
• the hollow main body having at least one first inlet, at least one first outlet, and a flow-guiding zone;
• the first inlet and the first outlet being arranged on the main body corresponding two substantially diagonally opposite ends of the flow-guiding zone;
• in the flow-guiding zone, there being provided a plurality of spaced flow-guiding members, such that a flow passage is defined between any two adjacent flow-guiding members and at least one flow passage is formed in the flow-guiding zone;
• and the flow-guiding members respectively having an end directing toward the first inlet and another opposite end directing toward the first outlet, wherein the hollow main body of the condensing device further includes an auxiliary diffusion section outward projected from the first inlet;
• the auxiliary diffusion section having an outer or first diffusion end and an inner or second diffusion end, and the first diffusion end having a size smaller than that of the second diffusion end;
• at least one heat-absorption unit having a vaporizing section, the vaporizing section being provided at two opposite ends with a second inlet and a second outlet;
• a first heat-transfer unit connecting the second inlet of the heat-absorption unit to the first outlet of the condensing device;
• and
• a second heat-transfer unit connecting the second outlet of the heat-absorption unit to the first inlet of the condensing device.
