Claims

[Scope of utility model registration request]

In a heat exchanger in which a large number of heat-absorbing fins 3 are arranged in parallel between tube sheets 1 at both ends, and heat-transfer tubes 4 are inserted and piped through the heat-absorbing fins 3, all of the heat-absorbing fins 3 are inserted into the insertion portions of the heat-transfer tubes 4. They have the same structure in which a short cylindrical collar 5 is protruded and an insertion hole 7 for a welding material 6 is bored just above it, and all of the heat absorption fins 3 are welded and fixed to the heat exchanger tube 4 by the welding material 6, and A heat exchanger characterized in that heat transfer tubes 4 are loosely inserted through tube sheets 1 at both ends without being fixed with a non-welding agent 10.
