Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a novel plate heat exchanger. Background Art

[0002] The new plate heat exchanger is a high-efficiency heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. When the internal heat exchange plate is damaged or needs to be replaced, the heat exchange plate needs to be disassembled. After searching, the Chinese patent authorization number CN209945090U discloses a detachable new plate heat exchanger, including a door frame, and tracks are arranged at the upper and lower ends of the door frame. The door frame is provided with a fixed end plate and a movable end plate. The heat exchange plate group is arranged between the fixed end plate and the movable end plate. The fixed end plate and the movable end plate are connected to each other by connecting rods arranged on both sides of the heat exchange plate group. The connecting rods include a front connecting rod and a rear connecting rod, and the front connecting rod and the rear connecting rod are connected by threads. When the heat exchange plate group is disassembled and assembled, it is only necessary to separate the front connecting rod and the rear connecting rod, and then move the movable end plate to remove the part of the heat exchange plate that needs to be removed. The heat exchange plate that does not need to be replaced can still be placed in the heat exchanger. The disassembly and installation are convenient and quick, and the heat exchange plate is not easily damaged due to disassembly. However, when the device is in use, the internal heat exchanger plates are disassembled and taken out by moving the movable end plate. After the movable end plate is moved, the heat exchanger plates are still tightly fitted to the side walls of the fixed end plate. If the heat exchanger plates are forcibly moved, the layered parts inside the heat exchanger plates are easily damaged. Therefore, even if the device can be easily disassembled, the internal heat exchanger plates cannot be easily taken in and out. Utility Model Content
