Description

Technical Field

[0001] The utility model relates to a plate type heat exchanger, in particular to a heat exchange plate assembly and a tube box type heat exchanger. Background Art

[0002] The existing document CN218469638U discloses a large-channel heat exchange element and a flue gas heat exchanger, including a heat exchange plate, the space between adjacent heat exchange plates as a refrigerant channel, the space outside the heat exchange plate and adjacent to the refrigerant channel as a heat medium channel, a partition bar is provided in the refrigerant channel, and the partition bar is clamped between two adjacent heat exchange plates. The flue gas heat exchanger adopts the large-channel heat exchange element. The refrigerant channel in the heat exchange element is divided into multiple channels for medium flow by the partition bar, so that the refrigerant medium can flow smoothly along the divided channels, avoiding the heat exchange medium from flowing too slowly or even unable to flow at the diagonal part of the heat exchanger far away from the inlet of the refrigerant medium. The heat exchange plate is supported by the partition bar, and the anti-deformation ability of the heat exchange element and the heat exchanger is guaranteed. In this scheme, the heat exchange plate is mainly supported by the partition bar to ensure the anti-deformation ability of the heat exchange element and the heat exchanger. However, it needs to be further optimized in terms of eliminating the cold and hot expansion ability of the heat exchange medium. Utility Model Content
