Rib slot, several diamond grooves are outwards expanded successively by the center of the second reinforcing plate, and the relatively long-diagonals of several diamond grooves is along
The vertical direction of two reinforcing plates is set, and several rib slots are arranged on the periphery of outermost diamond groove, and several rib slots are with diamond groove
Any one diagonal is symmetrical set for symmetry axis.
Further, the section of diamond shape chimb, fin, diamond groove and rib slot is isosceles trapezoid.
Further, the section of diamond shape chimb, fin, diamond groove and rib slot is rectangle.
Further, the first reinforcing plate and heat exchanger top end plate soldering connection, the second reinforcing plate and exchanger base end
Plate soldering connection.
Further, the first reinforcing plate and the second reinforcing plate are steel plate.
The utility model has the beneficial effect that：The utility model sets diamond shape chimb and fin on the outside of the first reinforcing plate,
Set on the outside of second reinforcing plate with the matched diamond groove of diamond shape chimb and with the matched rib slot of fin, by mold in compacting plus
During decorative pattern on strong plate, upper and lower mold core can form a closed loop completely, and the stress distribution of mold core is highly uniform, stress concentration
Small, mold core intensity is higher, and die life is long, and the plate that can be suppressed is more；Diamond shape chimb, fin, diamond groove and rib slot are
Full symmetric, and diamond shape chimb and diamond groove can form a closed loop, and the stress distribution of reinforcing plate is also highly uniform
, stress concentration is small, and the intensity of reinforcing plate is higher, and the pressure-resistant performance for the heat exchanger being assembled is more preferable.The utility model structure
It is reasonable to set, and the stress distribution of reinforcing plate is highly uniform, and stress concentration is small, and reinforcing plate intensity is higher, the heat exchange being assembled
The pressure-resistant performance of device is more preferable.
