Raised 122 quantity is set to into two, and two projections 122 are symmetricly set in flat hole 121, are so both ensured
20 insertion depth of flat tube is accurately positioned, raised 122 quantity is reduced as far as possible again, so as to simplifying the knot of union joint 12
Structure, reduces the manufacturing cost of product.Preferably, two projections 122 respectively positioned at flat hole 121 width two ends or
The two ends of thickness.
As the end face of flat tube 20 is plane, therefore setting raised 122 is flat near one end of the insertion end in flat hole 121
Face, can be effectively increased flat tube 20 and raised 122 contact area, and then increase the reliability of positioning of raised 122 pairs of flat tubes 20.
Further, when raised 122 quantity for it is multiple when, multiple raised 122 be located near one end of the insertion end in flat hole 121 it is same
In plane, this ensure that flat tube 20 while be connected on multiple raised 122, and then can ensure that multiple raised 122 can
Positioning action is played to the insertion depth of flat tube 20.
The raised 122 insertion depths that flat tube 20 is near the distance between one end of the insertion end in flat hole 121 and insertion end
Degree, arrange flat tube 20 insertion depth avoided between 5mm to 10mm, both flat tube 20 insertion depth it is too small cause connection not
Reliable problem, turn avoid that 20 insertion depth of flat tube is too deep to be caused union joint 12 long to cause product cost higher or impact
The situation of 20 heat exchange efficiency of flat tube occurs.
In other embodiments of the present utility model, location division is other shapes, such as：The net being arranged in flat hole 121
Shape structure, circulus etc., as long as positioning action can be played to the insertion depth of flat tube 20, and ensure flat tube 20 and header
Connection between chamber 111, as these technical schemes can realize the purpose of this utility model, and without departing from this reality
With new design philosophy and objective, thus it will be understood by those of skill in the art that these technical schemes all should be in this practicality
