[0054] Working principle:

[0055] Component installation and connection:

[0056] The mounting plate 105 is welded at both ends of the inner wall of the exchanger frame 1, the second hierarchical blocking strip 102 is stacked on the first hierarchical blocking strip 101, and the second hierarchical blocking strip 102 can be inserted on the mounting plate 105 and connected with the exchanger frame 1 during installation, and the latch 103 is inserted in the second hierarchical blocking strip 102, and the latch 103 is also inserted in the first hierarchical blocking strip 101, so that the first hierarchical blocking strip 101 and the second hierarchical blocking strip 102 are connected by the latch 103.
