Closed assembly is carried out, the heat exchanger core body of the structure of similar sandwich style is formed, and is applied one on outermost two is with flat tube or side plate
By the heat exchanger core body bonding of sandwich style firmly, this causes whole manufacturing process easier to fixed fastening force, and fin with it is flat
Connection between pipe tightr, heat conduction is more efficient.In addition, after corrugated fins and flat tube closed assembly, flat tube can be supported by fin,
The intensity requirement that liquid collecting cavity is supported is relied on so as to reduce flat tube two ends.
Either between flat tube and fin or between flat tube and liquid collecting cavity, complete gluing side is present invention employs
Formula.This avoids part bonding portion and welds brought defect, it is to avoid negative shadow of high temperature during welding to original bonding
Ring；Aluminum alloy surface oxidation caused by the high temperature institute used by soldering is avoided, so as to damage the cementability of aluminum alloy surface；Additionally,
It also avoid soldering need to using particular aluminum alloy material and caused cost is higher.In addition, flat tube of the present invention, fin
With liquid collecting cavity all preferably using ripe structure, this not only contributes to and prior art rapid abutting joint, it is to avoid adopt excessive glue groove
Increase with the cost that the special construction such as injecting glue groove brings, the assembling that it also avoid being brought using aciculiform fin is difficult and poorly efficient
Rate.
What deserves to be explained is, relative to prior art, the present invention provide not only and assemble this with regard to the complete gluing of heat exchanger
One new basic solution, additionally provides the sides such as sealing adhesive strength, heat transfer efficiency, durable anti-corrosion, lightweight, production efficiency
The solution of face deep-seated problem.
