Eddy fluid heat exchange device

An eddy fluid heat exchange device comprising:

• a compound tube assembly comprising
• an outer tube;
• an inner tube mounted in the outer tube;
• an eddy passage formed between the outer tube and the inner tube and extending along an axis of the inner tube, the outer tube having
• a guiding exit formed at an end of the eddy passage;
• an eddy guiding structure mounted at the compound tube assembly, disposed at another end, which is opposite to the guiding exit, of the eddy passage;
• the eddy guiding structure having
• a guiding entrance connected to the eddy passage;
• and
• at least one eddy deflecting structure mounted in the eddy passage of the compound tube assembly, spaced apart from the eddy guiding structure, and having
• a sleeve being conic;
• multiple vanes annularly mounted on the sleeve;
• and
• multiple spiral deflecting channels defined by and separated by the multiple vanes, with each adjacent pair of vanes of the multiple vanes defining therebetween one respective spiral deflecting channel of the multiple spiral deflecting channels;
• each one of the spiral deflecting channels having an inlet end and an outlet end both respectively connected to the eddy passage;
• wherein a bore of each one of the spiral deflecting channels gradually reduces in size from the inlet end to the outlet end;
• wherein a high pressure fluid is fed into the guiding entrance;
• after passing through the eddy guiding structure, the high pressure fluid eddies and enters the eddy passage;
• the high pressure fluid eddies when passing through the multiple spiral deflecting channels;
• and the high pressure fluid is discharged from the guiding exit after exchanging heat with the inner tube or the outer tube.
