Through setting up protruding on the sealing strip installing frame, be provided with the recess (not shown in the figure) correspondingly with each first sealing strip 21, realize protruding joint with first sealing strip, conveniently set up first sealing strip, and also can not drop when first sealing strip does not receive horizontal extrusion. Similarly, flanges at two ends of the air hose soft joint can be provided with protrusions in the same mode, and the second sealing strip is correspondingly provided with a groove, so that the second sealing strip is clamped conveniently.
It will be appreciated that when the plate heat exchanger is of a larger size, no section of the frame in the X-direction is provided with two sealing strip mounting frames (as shown in fig. 1), respectively.
Referring to fig. 2 and 3, further, the bottom frame is provided with two sets of rails along the Y direction, and each heat exchange core can move linearly along the corresponding set of rails; a front door is detachably provided on one side of the housing in the Y direction. This setting is convenient for the heat exchange core to push the casing inside along the Y direction, and can not take place to interfere with sealing strip installing frame in the push-in process.

The above-mentioned connection pipe 92 may be connected to the external blower 90 through a pipe 91. By this arrangement, it is convenient for the air flow to blow to the outer sides of the two heat exchange plates uniformly (as shown by arrows in fig. 4), and the heat exchange effect is improved.
The following briefly applies to the structural principles: during assembly, each sealing strip mounting plate 20 is fixed at two ends of the frame 11, and each first sealing strip 21 is clamped on the corresponding sealing strip mounting plate 20; each second sealing strip 41 is clamped on flanges 401 at two ends of the air pipe soft joint 40 in advance; each jack 50 is respectively arranged on the corresponding jack mounting plate 14; the two heat exchange cores 30 are respectively pushed into the shell along each group of tracks from the Y direction, and then an air hose soft joint 40 is arranged between the two heat exchange cores 30; by operating the two jacks, the two jacks tightly support the two flanges of the air pipe soft joint on the adjacent heat exchange core body, and the two jacks are operated to continuously apply force until the two heat exchange core bodies are tightly supported by the corresponding sealing strip fixing plates. Because both ends of each heat exchange core body are in a tight state, and because the first sealing strip and the second sealing strip are arranged, both ends of each heat exchange core body are in a sealed state, and finally the door on the shell is closed. When the heat exchange core is required to be cleaned, the front door (not shown in the figure) is only required to be opened, each jack is loosened, each heat exchange core can be pulled out of the shell along the Y direction, only the two heat exchange cores and the air pipe soft joint are detached, and other parts are all positioned at the original installation positions, so that the disassembly and the reassembling are very simple. The sealing strip is preferably made of rubber, has certain elasticity and has good static sealing effect after being extruded.
During normal operation, the first air flow enters one heat exchange core through a flange interface on the shell from an external pipeline (not shown in the figure), then enters the air pipe soft joint, enters the other heat exchange core, and is discharged from the other flange interface; the second path of air flow exchanges heat with the first path of air flow when entering from the top of the shell and flowing through the outer sides of the two heat exchange cores, and finally flows out from an outlet (not seen from the view angle of the drawing) at the bottom of the shell; thereby realizing the cross flow of two paths of air flows and carrying out heat exchange.
From the above analysis, the present invention has at least the following advantages over the prior art: (1) The sealing by beating glass cement is avoided, the heat exchange core body and the shell are detachably connected, and the assembly is simple and quick; (2) The first sealing strip and the second sealing strip are subjected to the pretightening force exerted by the jack, so that the sealing effect is good; (3) When it is desired to clean the heat exchange core, the heat exchange core can be quickly removed and removed from the housing without the need to replace the entire plate heat exchanger as in the prior art.
It should be understood that equivalents and modifications will occur to others skilled in the art based on the present invention and its spirit, as follows: the simple change or replacement does not change the essence of the technical scheme of the invention, and the simple change or replacement belongs to the protection scope of the invention.
