[0006] Preferably, the heat exchanger body comprises a frame, and the plate structure is arranged in the frame.

[0007] Preferably, a sealing gasket and an end sealing gasket are provided between the fixed pressing plate and the adjacent plate.

[0008] Preferably, a medium label is provided on the fixed pressing plate, and the medium label is fixed to the fixed pressing plate by label rivets.

[0009] Preferably, the shaft is fixed to the movable pressure plate by bolts and washers.

[0010] Preferably, eye screws are provided at the top ends of the fixed pressing plate and the movable pressing plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model adopts a shallow corrugated design, eliminates the design of columns and upper and lower guide rods, develops a new frame structure, reduces the volume of the heat exchanger to only the size of the heat exchange core, has a compact structure, is easy to install, and is light in weight. On the basis of ensuring the efficient, safe and stable operation of the heat exchanger, it can be disassembled for cleaning at any time when problems such as fouling and dirt on the plates are encountered.

DETAILED DESCRIPTION

[0018] A detachable plate heat exchanger for a building heat exchanger unit includes a heat exchanger body, on which an inlet and outlet structure is provided, the inlet and outlet structure including a hot side inlet A, a hot side outlet B, a cold side inlet C and a cold side outlet D; the heat exchanger body includes a plate structure, the plate structure includes a plurality of plates 3; a fixed pressing plate 1 is provided on one side of the plate structure, and a movable pressing plate 9 is provided on the other side; the plate structure is fixed together with the fixed pressing plate 1 and the movable pressing plate 9 on both sides through a plurality of shafts 8.

[0019] The fixed pressing plate 1 is provided with an opening structure in which a hot side inlet A, a hot side outlet B, a cold side inlet C and a cold side outlet D cooperate with each other; the heat exchanger body includes a frame, and the plate structure is arranged in the frame; a sealing gasket 4 and an end sealing gasket 2 are provided between the fixed pressing plate 1 and the adjacent plate 3; a medium label 5 is provided on the fixed pressing plate 1, and the medium label 5 is fixed to the fixed pressing plate 1 by a label rivet 6; the shaft 8 is fixed to the movable pressing plate 9 by bolts 11, washers 10, bolts 13 and flat washers 12; mounting bolt holes are provided at the tops of the fixed pressing plate 1 and the movable pressing plate 9, and eye screws 7 are matched in the mounting bolt holes.

[0020] The plate 3 is divided into a hot side flow channel and a cold side flow channel arranged in a staggered manner. The cold side is provided with a cold side outlet pipe and a cold side inlet pipe, and the hot side is provided with a hot side inlet pipe and a hot side outlet pipe, which are connected to each inlet and outlet respectively; the plate 3 adopts a shallow corrugated design to improve the heat exchange efficiency of the cold and hot side media;

[0021] The present embodiment eliminates the design of columns and upper and lower guide rods and adopts a frame structure, reducing the volume of the heat exchanger to only the size of the heat exchange core. The heat exchanger has a compact structure, is easy to install, and is light in weight. If problems such as fouling of the plates occur, the heat exchanger can be disassembled and cleaned at any time. The present embodiment can directly open the movable pressing plate 9 from the back, so that the sewage generated during the cleaning and maintenance of the equipment plates can be discharged in time.

[0022] During operation, after the high-temperature medium enters the heat exchanger through the hot side inlet pipe, the high-temperature medium enters the hot side flow channel of the plate 3. At the same time, the low-temperature medium enters the heat exchanger from the cold side inlet pipe and enters the cold side flow channel of the plate 3. After the high-temperature medium and the low-temperature medium perform heat exchange, the high-temperature medium flows out from the hot side outlet pipe, and the low-temperature medium flows out from the cold side outlet pipe.
