The inner side of body import 7 and outlet 8 is equipped with the interior of second fluid import 9 on the second salient point 21, the second heat exchanger plates 2 and outlet 10
Side is equipped with the second concave point 22.Double-plate heat exchanger of the present invention, in the first concave point 11 and the second concave point 22 bottom-up
Projection has one and half high short raised lines 121, and short raised line 121 is connected with the both sides of concave point；First salient point 12 and the second salient point 21 are equal
One short groove 122 is provided with from top down, short groove 122 is connected with the both sides of salient point.Double-plate heat exchanger of the present invention, is being changed
First concave point 11 and the second salient point 21 on the hot plate group left side are corresponded, a pair of first salient point 12 on the right and the second concave point 22 1
Should, short raised line 121 and short groove 122 corresponding thereto form short passage.Double-plate heat exchanger of the present invention, some first length
In the long raised line 4 of groove 3 and first, at least two edges in the first heat exchanger plates 1.Double-plate heat exchanger of the present invention, length is recessed
Groove, long raised line and heat exchanger plates while it is parallel or with heat exchanger plates while between form angle, when forming angle, angle is less than
90°。
The present invention forms some long-channels by half high long recess and long raised line, so as to increase the cross-sectional passage at the position
Also make the region local temperature more uniform so that the region flow velocity improves more difficult icing, further increase heat exchange effect
Rate, and extend the service life of heat exchanger plates.

Embodiment
Double-plate heat exchanger as Figure 1-4, including some groups of plate packages being sequentially overlapped, every group of plate package are equal
Including the first heat exchanger plates 1 and the second heat exchanger plates 2, the first heat exchanger plates 1 are covered on the second heat exchanger plates 2, and the first heat exchanger plates 1 and second are changed
Formed between first fluid passage, two adjacent groups plate package and formed on second fluid passage, the first heat exchanger plates 1 between hot plate 2
The right side on surface is provided with some half the first high long recess 3 from top down, the left side of the upper surface of the first heat exchanger plates 1 from
Bottom up projection has some half the first high long raised lines 4；The right side of the upper surface of second heat exchanger plates 1 is raised bottom-up
There are some half the second high long raised lines 5, the left side of the upper surface of the second heat exchanger plates 1 is provided with some half high from top down
Second long recess 6, some second length of some right sides of first long recess, 3 and second heat exchanger plates 1 of the right side of the first heat exchanger plates 1
