[0017] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0018] A detachable plate-fin heat exchanger, comprising a base plate 4, a pressure plate 1 and a plurality of heat exchange units 3 between the base plate 4 and the pressure plate 1, wherein the base plate 4 and the pressure plate 1 are both provided with a connecting plate at one end, and a slot is provided at one end of the connecting plate to facilitate screws to pass through the connecting plate and fix with other devices, and the base plate 4 and the pressure plate 1 are both provided with connecting pipes connected with the heat exchange unit 3, and the heat exchange unit 3 includes a partition, a fin, a seal, and a guide plate, and the base plate 4 is provided with two baffles 5 that abut against the heat exchange unit 3, and the longitudinal section of the baffle 5 is L-shaped, and the baffle 5 is plugged with the pressure plate 1;

[0019] The pressing plate 1 is provided with a clamping assembly clamped with the baffle 5, and the clamping assembly includes a clamping rod 10 clamped with the baffle 5 and a driving assembly driven and connected to the clamping rod 10. One end of the clamping rod 10 is provided with a slope 11, and one end of the baffle 5 is provided with a clamping groove matched with the slope 11, so that the force between the pressing plate 1 and the base plate 4 can be adjusted by controlling the insertion depth of the clamping rod 10, thereby avoiding leakage during use;

[0020] The driving assembly includes a worm 6, a rack connected to a rod, a first rotating shaft 9 and a second rotating shaft rotatably connected to the pressure plate 1. The surface of the first rotating shaft 9 is provided with a first gear and a third gear 12 meshing with the rack. The surface of the second rotating shaft is provided with a worm wheel 7 meshing with the worm 6 and a second gear 8 meshing with the first gear. The first gear and the second gear 8 are both bevel gears. One end of the worm 6 is provided with a handwheel 2 that passes through the pressure plate 1 and is rotatably connected to the pressure plate 1. The surface of the handwheel 2 is provided with multiple anti-slip strips to facilitate the rotation of the handwheel 2.

[0021] Working principle: The clamping rod 10 is used to fix the pressure plate 1 and the baffle 5, so that the base plate 4, the baffle 5 and the pressure plate 1 cooperate with each other to clamp the heat exchange single ring. If the fixing effect is not ideal, the hand wheel 2 can be turned forward, such as Figure 3 As shown, the hand wheel 2 drives the worm 6 to rotate forward, the worm 6 drives the second shaft to rotate forward through the worm wheel 7, and the second shaft drives the second gear 8 to rotate forward, as shown in FIG. Figure 4 As shown, the second gear 8 drives the first rotating shaft 9 to rotate counterclockwise through the first gear, and the first rotating shaft 9 drives the third gear 12 to rotate counterclockwise, and the third gear 12 allows the clamping rod 10 to be further inserted into the baffle 5 through the rack, as shown in FIG. Figure 3 As shown, the clamping rod 10 squeezes the baffle plate 5 through the slope 11 to make it close to the hand wheel 2, so that the distance between the base plate 4 and the pressure plate 1 is reduced, and the force of the base plate 4 and the pressure plate 1 on the heat exchange unit 3 is increased. Due to the unidirectional transmission of the worm 6 and the worm wheel 7, the worm wheel 7 can be prevented from rotating by itself.

[0022] When disassembly is required, Figure 1 As shown, by rotating the hand wheel 2 in the opposite direction, the hand wheel 2 drives the second shaft to rotate in the opposite direction, the second shaft drives the second gear 8 to rotate in the opposite direction, the second gear 8 drives the first shaft 9 to rotate clockwise through the first gear, the first shaft 9 drives the third gear 12 to rotate clockwise, and the third gear 12 moves the clamping rod 10 away from the baffle 5 through the rack to release the fixation. At this time, the pressure plate 1 can be moved away from the base plate 4 to be removed, and the heat exchange unit 3 that is no longer fixed can be conveniently removed.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
