The connecting rods penetrate through the fixed baffle and the activity baffle. A nut sleeve for fixing is arranged on the connecting rods. Rollers are arranged on both sides of the moving trolley. Roller grooves matched with the rollers are arranged on the lower guide plate. A limiting protrusion is arranged on the guide cover. A guide groove matched with the limiting protrusion is arranged on the upper guide plate.

[0005] Preferably, a sloping ramp is arranged at one end of the lower guide plate close to the activity baffle.

[0006] Preferably, a car door is also arranged on the moving trolley. The car door is connected to the moving trolley through a hinge.

[0007] Preferably, a sealing strip is arranged between the heat exchange fins.

[0008] The beneficial effect of the utility model is that the activity baffle and the heat exchange fins can move along the roller grooves on the lower guide plate through the moving trolley, and a guide cover is arranged at the top of the heat exchange fins, so that the activity baffle and the heat exchange fins can be easily taken out of or installed in the heat exchanger, which is convenient for maintenance and cleaning.

Detailed implementation manners

[0013] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0014] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0015] According to Figure 1 and Figure 2 shown, a detachable plate heat exchanger includes a fixed baffle 1. Upper and lower guide plates 2 and 3 are respectively arranged at the upper and lower ends of the fixed baffle 1. A guide cover 8 is arranged on the lower guide plate 3. A moving trolley 7 is arranged on the upper guide plate 2. A movable baffle 4 and a heat exchange fin 5 are further arranged between the moving trolley 7 and the guide cover 8. The movable baffle 4 and the heat exchange fin 5 move along the roller groove 31 on the lower guide plate 3 through the moving trolley 7, so as to realize the easy removal and reinstallation of the movable baffle 4 and the heat exchange fin 5. The heat exchange fin 5 is arranged between the fixed baffle 1 and the movable baffle 4. A plurality of connecting rods 6 are arranged on both sides of the fixed baffle 1 and the movable baffle 4. The connecting rods 6 penetrate through the fixed baffle 1 and the movable baffle 4. A nut sleeve 61 for fixing is arranged on the connecting rod 6; Roller 71 is arranged on both sides of the moving trolley 7. A roller groove 31 for cooperating with the roller 71 is arranged on the lower guide plate 3. A limit projection 81 is arranged on the guide cover 8. A guide groove 21 for cooperating with the limit projection 81 is arranged on the upper guide plate 2, ensuring that the heat exchange fin 5 always maintains the correct direction and position during the movement.

[0016] One end of the lower guide plate 3 close to the movable baffle 4 is provided with an inclined slope 32, which is convenient for the moving trolley 7 to move on the lower guide plate 3.

[0017] A door 72 is also provided on the mobile trolley 7. The door 72 is connected to the mobile trolley 7 by a hinge, which facilitates the installation of the baffle 4 and the heat exchange fins 5 when they are movable.

[0018] A sealing strip 51 is provided between the heat exchange fins 5. The sealing strip 51 effectively fills the gap between the heat exchange fins 5, prevents the leakage of the fluid medium, and improves the safety and reliability of the heat exchanger.
