[0035] like Figure 1As shown, the filtering device 1 for a heat exchange unit of the present utility model is connected in a pipeline. The circulating water flows through the first pipeline 2, enters the filtering device 1 for filtration, and the filtered circulating water enters the heat exchanger through the second pipeline 3. At the same time, refer to Figures 2 to 4 , the filtering device 1 includes a housing 11, a filter element 12, a mounting assembly 13, a first elastic member 14, and a sensor 15. The housing 11 is generally a hollow cylinder with openings at both ends. The filter element 12 is movably installed in the housing 11. The mounting assembly 13 is installed in the filter element 12. The first elastic member 14 is sleeved on the filter element 12. The sensor 15 is installed in the housing 11 and is disposed opposite to the filter element 12.

[0036] In this embodiment, a first connection portion 114 and a second connection portion 115 are respectively provided at two axial ends of the housing 11, wherein the first connection portion 114 is connected to the first pipeline 2, and the second connection portion 115 is connected to the second pipeline 3. Preferably, the first pipeline 2 and the second pipeline 3 can be connected to the housing 11 by bolts. At the same time, refer to Figure 7 and Figure 8 , a plurality of first grooves 111 are formed on the inner side of the housing 11 by being recessed radially along the housing. Preferably, the first grooves 111 extend axially along the housing 11 from the first connection portion 413 to the middle position of the inner side of the housing 11. More preferably, the number of the first grooves 111 is 3, and the 3 first grooves 111 are arranged at equal intervals in the circumferential direction of the housing 11. A stop portion 112 is provided in the first groove 111, and the stop portion 112 is spaced from the first connection portion 114 by a certain distance. The side of the stop portion 112 facing the first connection portion 114 is provided as an inclined surface. The side of the stop portion 112 facing the second connection portion 115 is perpendicular to the axis of the housing 11 and parallel to the radius of the housing 11. Preferably, the distance between the inner side of the inclined surface of the stop portion 112 and the first connection portion 114 is greater than the distance between the outer side of the inclined surface and the first connection portion 114. The inner edge of the inclined surface of the stop portion 112 is provided as a rounded portion 118. A second groove 117 is provided on the stop portion 112, and the second groove 117 is arranged along the extending direction of the first groove 111, and the depth of the second groove 117 is less than the depth of the first groove 111.

[0037] A ring plate 113 is further provided on the inner side of the housing 11, and the ring plate 113 is located between the first groove 111 and the second connection portion 115. A plurality of mounting cylinders 116 are installed on the side of the ring plate 113 facing the first connection portion 114, and the first elastic member 14 is installed in the mounting cylinders 116. The mounting cylinder 116 is generally a hollow cylinder with openings at both ends. The first elastic member 14 is sleeved in the mounting cylinder 116, and both ends respectively abut against the ring plate 113 and the filter element 12.

[0038] The filter element 12 includes a filter main body 121, mounting holes 122 provided on the outer peripheral side of the filter main body 121, and struts 123 provided on the side of the filter main body 121 facing the second connecting portion 115. In this embodiment, the filter main body 121 is generally cylindrical, and a filter net is provided thereon. The mounting holes 122 are recessed from the outer peripheral side of the filter main body 121 along the radial direction of the filter main body 121. Preferably, the mounting holes 122 are stepped holes. The struts 123 are formed by extending along the axial direction of the filter main body 121. One strut 123 is provided between two adjacent mounting holes 122. The struts 123 pass through the through holes on the ring plate 113. The first elastic member 14 is sleeved on the struts 123 and abuts between the filter main body 121 and the ring plate 113. Preferably, the first elastic member 14 is a spring. The sensor 15 is mounted on the inner side of the second connecting portion 115 and is opposite to the end of the strut 123 away from the filter main body 121. The sensor 15 is a pressure sensor. When too much impurities accumulate on the filter main body 121, the filter element 12 is pressed towards the sensor 15 under the action of water flow, and the end of the strut 123 away from the filter main body 121 acts on the sensor 15. When the pressure reaches a certain value, the sensor 15 issues a warning. The staff can quickly install the filter element 12 on the housing 11 and quickly disassemble it from the housing 11 through the installation assembly 13. The installation assembly 13 is installed in the mounting holes 122 of the filter element 12.

[0039] Also refer to Figure 3 , Figure 5 and Figure 6, the mounting assembly 13 includes a mounting member 131 and a second elastic member 132 sleeved on the mounting member 131. In this embodiment, the mounting member 131 includes a mounting member body 311, a protrusion 312, a convex column 313, and a pushing portion 314. The mounting member body 311 is generally in the shape of a square block. The protrusion 312 is provided on one side of the mounting member body 311 facing the first groove 111, and the convex column 313 is provided on the side of the mounting member body 311 facing away from the first groove 111. Preferably, the protrusion 312 extends radially outward along the filter body 121, while the convex column 313 extends radially inward along the filter body 121. The second elastic member 132 is sleeved on the convex column 313. The size of the mounting member body 311 in the direction perpendicular to the extending direction of the protrusion 312 is larger than the size of the protrusion 312 in this direction. The mounting hole 122 sequentially includes a first part, a second part, and a third part from the outside to the inside along the radial direction of the filter body 121, where the size of the first part is smaller than that of the second part, and the size of the third part is also smaller than that of the second part. The protrusion 312 is engaged in the first part, the mounting member body 311 is engaged in the second part, and the second elastic member 132 is received in the third part. The protrusion 312 protrudes from the filter body 121 under the action of the second elastic member 132 and is engaged in the first groove 111 of the housing 11. The pushing portion 314 is provided on one side of the mounting member body 311 facing the first connecting portion 114. An opening 124 is formed on one side of the filter body 121 facing the first connecting portion 114, and the opening 124 communicates with the mounting hole 122, and the pushing portion 314 extends out from the opening 124.

[0040] When the filter element 12 needs to be installed in the housing 11, align the protrusion 312 of the mounting assembly 13 with the first groove 111 of the housing 11, and push the filter element 12 along the axial direction of the housing 11. The protrusion 312 is engaged in the first groove 111. When the protrusion 312 is pushed to the stop portion 112, under the action of the inclined surface of the stop portion 112, the protrusion 312 moves radially inward along the filter body 121, and the protrusion 312 is partially engaged in the second groove 117. When the protrusion 312 is pushed to the side of the stop portion 112 facing away from the first connecting portion 114, the protrusion 312 enters the first groove 111 from the second groove 117 under the action of the second elastic member 132. Under the action of the first elastic member 14, the protrusion 312 is stopped on the side of the stop portion 112 facing away from the first connecting portion 114, thereby installing the filter element 12 in the housing 11.

[0041] When the filter element 12 needs to be removed from the housing 11, push the pushing portion 314 of the mounting assembly 13 radially inward along the filter body 121, so that the protrusion 312 moves radially inward along the filter body 121, causing the protrusion 312 to completely disengage from the first groove 111, so that the filter element 12 can be taken out of the housing 11.
