Carry out closed assembly, form the heat exchanger core body of the structure of similar sandwich style, and outermost two with flat tube or side plate on apply one
Fixed fastening force by bonding for the heat exchanger core body of sandwich style firmly, this makes whole manufacturing process easier, and fin is with flat
Connection between pipe is tightr, heat conduction is more efficient.It addition, after corrugated fins and flat tube closed assembly, flat tube can be supported by fin,
Thus reduce the requirement of strength that flat tube two ends Dependency Set sap cavity supports.
No matter it is between flat tube and fin or between flat tube and liquid collecting cavity, entirely present invention employs gluing side
Formula.This avoids part bonding portion and welds the defect brought, it is to avoid high temperature during welding is to original bonding negative shadow
Ring；Avoid the aluminum alloy surface oxidation that the high temperature used by soldering is caused, thus damage the cementability of aluminum alloy surface；Additionally,
It also avoid soldering and need to use particular aluminum alloy material and the cost that causes is higher.It addition, flat tube of the present invention, fin
All preferably employ the structure of maturation with liquid collecting cavity, this not only contributes to and prior art rapid abutting joint, it is to avoid use the glue groove that overflows
The cost brought with the special construction such as injecting glue groove increases, and it also avoid the assembling difficulty and poor efficiency using aciculiform fin to be brought
Rate.
What deserves to be explained is, relative to prior art, the present invention provide not only the complete gluing assembling about heat exchanger this
One new basic solution, additionally provides the sides such as sealing adhesive strength, heat transfer efficiency, anticorrosion be durable, lightweight, production efficiency
The solution of face deep-seated problem.
