Title:
SPIRAL HEAT EXCHANGER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/116960
Kind Code:
A1
Abstract:
A spiral heat exchanger and manufacturing method therefor. The spiral heat exchanger comprises: a mandrel (1) having an axis extending left and right; and a heat-conducting thin strip (2) spirally wound around the periphery of the mandrel (1) for at least three circles. The heat-conducting thin strips (2) of any two adjacent circles are spaced apart by a certain distance; baffle ribs (3) extending left and right are supported between the heat-conducting thin strips (2) of any two adjacent circles; the baffle ribs (3) are arranged in sequence along a radial direction of the mandrel (1), so as to form a plurality of hot fluid flow channels (4) and a plurality of cold fluid flow channels (5) which are arranged alternately along the radial direction of the mandrel (1); each cold fluid outlet (5b) is provided with a first blocking bar (6) for blocking a portion of the cold fluid outlet (5b); each hot fluid outlet (4b) is provided with a second blocking bar (7) for blocking a portion of the hot fluid outlet (4b); the first blocking bars (6) are arranged in sequence along a first radial direction (R1), and the second blocking bars (7) are arranged in sequence along a second radial direction (R2). The spiral heat exchanger is compact and ingenious in structure and small in flow resistance, has a large heat exchange area and high heat exchange efficiency, and is quite suitable for gas-gas heat exchange and gas-liquid heat exchange.
