Abstract
The present invention is directed to providing a hot water heat exchanger which has a simple piping structure and minimizes a flow passage length therein, thereby minimizing flow resistance. To this end, the hot water heat exchanger is characterized in that the first adaptor and the second adaptor are connected to the partition configured to define one side surface of the heat exchanging part, a first heating water circulation passage through which the heating water introduced from the inlet port of the first adaptor flows is formed at the space between the partition and the partition adjacent thereto, a first direct water circulation passage through which the direct water introduced from the inlet port of the second adaptor flows is formed at the space between the partition configured to define the other side surface of the heat exchanging part and the partition adjacent thereto, and a plurality of second heating water circulation passages through which the heating water passing through the first heating water circulation passage flows, and a plurality of second direct water circulation passages through which the direct water passing through the first direct water circulation passage flows are alternately formed between the first heating water circulation passage and the first direct water circulation passage.
