Claim:
1. A waste heat energy recovery system comprising: a conduit through which a first fluid for transporting heat from a heat source flows; and a heat exchanger at least partially disposed inside the conduit for transferring heat from the first fluid to a second fluid, wherein the heat exchanger comprises: a first tube disposed within the conduit, the first tube having an inner wall defining a first passageway through which the first fluid flows; a second tube disposed concentrically between the conduit and the first tube, wherein an outer wall of the second tube and an inner wall of the conduit define a second passageway through which the first fluid flows, and wherein an outer wall of the first tube and an inner wall of the second tube define a fluid channel through which the second fluid flows, the fluid channel being in fluid communication between the inlet and the outlet for circulating the second fluid; and a connector comprising a pipe having a first end connected to either the inlet or the outlet and a second end connected to a port on the inner wall of the first tube that connects to the fluid channel.
