摘要： A flow passage connecting apparatus for a heat exchanger includes a boss formed of a resin material in a columnar shape and having a plurality of through-holes for each receiving from one side one end of a heat exchanger tube made of a resin material, and a coupler made of a resin material and having a body portion formed in a circular cylindrical shape. The body portion is configured to receive therein a part of the boss on the other side opposite to the one side and to be connected to the boss by at least one of threaded engagement and full-circle welding. The connecting apparatus further includes first and second seal structures sealing between the boss and the body portion. The body portion has a communication hole formed at a position between the first and second seal structures to communicate between an inside and outside of the body portion.
