Description

Technical Field

[0001] The utility model relates to a heat exchanger sheet of a plate-type heat recovery device which is easy to assemble and belongs to the technical field of plate-type heat recovery devices. Background Art

[0002] Plate heat recovery is a common heat exchange equipment, which is widely used in industrial production and energy fields. The main function of plate heat recovery is to transfer heat energy from one fluid to another to achieve heat energy transfer, improve heat energy utilization efficiency, reduce energy consumption and environmental pollution.

[0003] The existing plate heat recovery devices in the heat recovery industry generally use A and B plate stacking or A plate rotated 180 degrees stacking process. When stacking the heat exchanger plates, the four sides need to be stacked, so there are many process steps, a high probability of air leakage, and low assembly efficiency. If the A and B plate stacking process is adopted, the A plate and the B plate must be distinguished during assembly, and the assembly sequence cannot be wrong, otherwise the plates need to be replaced again; if the A plate rotation stacking process is adopted, the 2nd, 4th, 6th, 8th and other even-numbered plates must be rotated 180 degrees to achieve correct assembly. The above two stacking processes require the operator to concentrate highly, otherwise assembly errors are likely to occur, and the plates need to be replaced again or the heat exchanger plates need to be rotated again to achieve assembly stacking. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide a plate-type heat recovery heat exchanger that is easy to assemble, does not require stacking of the four sides, reduces the probability of air leakage, reduces the assembly process steps, improves productivity, and is easy to assemble and reduces assembly errors.

[0005] The utility model discloses a heat exchanger plate for a heat recovery device that is easy to assemble, comprising a heat exchanger plate body, wherein a "J"-shaped protrusion is arranged in the middle of the heat exchanger plate body, and the "J"-shaped protrusion separates the heat exchanger plate body into two heat exchanger plate units, wherein the two heat exchanger plate units are symmetrical about the "J"-shaped protrusion, and the heat exchanger plate is folded along the center line of the "J"-shaped protrusion when being assembled.

[0006] The technical solution of the utility model is to provide a plate-type heat recovery heat exchanger that is easy to assemble. A "J"-shaped protrusion is provided on the heat exchanger body. During assembly, the heat exchanger is folded along the center line of the "J"-shaped protrusion without overlapping the folded edges, thereby reducing the probability of air leakage and the number of assembly process steps. At the same time, the heat exchanger body is symmetrical about the folded edges and does not need to be distinguished during assembly, thereby avoiding assembly errors.

[0007] Preferably, the other three unconnected sides of the heat exchanger unit are provided with folded edges, and the folded edges are L-shaped.

[0008] Furthermore, the heights of the folded edges are equal, and the directions of two adjacent folded edges of the same heat exchange plate unit are opposite.

[0009] Preferably, the height of the X-shaped protrusion is equal to the height of the folded edge.

[0010] Preferably, the heat exchange plate unit is further provided with a plurality of raised areas and recessed areas, and the raised areas and recessed areas are arranged in a linear array.

[0011] Furthermore, the raised areas and recessed areas are alternately arranged on the heat exchanger unit.

[0012] Furthermore, the height of the raised area is equal to the depth of the recessed area, and the height of the raised area and the depth of the recessed area are equal to the height of the folded edge; after the heat exchanger is assembled, the raised areas are in contact with each other, and the recessed areas are in contact with each other. The raised areas and the recessed areas are used to support the air duct and increase the strength of the plate heat recovery device.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The heat exchanger fin of the plate-type heat recovery device which is easy to assemble described in the utility model can be folded in half along the center line of the "X"-shaped protrusion on the heat exchanger fin during assembly. The folded edges do not need to be overlapped, and only the remaining three edges need to be overlapped, thereby reducing the number of assembly process steps, effectively reducing the air leakage rate, improving product quality, reducing labor intensity, and improving labor productivity. At the same time, the heat exchanger fin body is symmetrical about the folding line, and does not need to be distinguished during assembly, thereby avoiding assembly errors.
