Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP3922088
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a compact heat exchanger having excellent pressure proofness.
SOLUTION: This heat exchanger 10 is formed by arranging first flow passages 2 and second flow passages 6 in different surfaces of a plate 3 working as a partition. Each first flow passage 2 is formed of a through-hole formed by punching a first flow passage plate 1 in the plate thickness direction, and the second flow passages 6 are formed between the second flow passage plate 5 and the partition plate 3. With this structure, fine flow passages having excellent pressure proof can be structured with a simple method using the through- holes provided in the flat plate as the first flow passages 2. Furthermore, a flat and wide heat transfer surface is formed by arranging these flow passages in a surface, and a thin heat exchanger can be structured. A compact heat exchanger having excellent pressure proofness is thereby provided.
