Method for manufacturing a heat exchanger |
摘要 |
A heat exchanger includes a pair of headers, a plurality of flattened oval heat exchange tubes, and a plurality of fins positioned between the headers over the length of the heat exchange tubes. The tubes are connected to the headers through a plurality of elongated holes in the header that have tapered lips. The lip taper forms an annular depression around the tube upon insertion that provides a good structural integrity. The connector holes are formed in each of the headers by a pressing method that eliminates header warping and produces dimensionally accurate hole shapes.
