[0031] The unit condenser assembly provided by the utility model embodiment, when unit is in normal operating state, reversing valve 2 sets condenser body 1 to normal operating state, in this state, brush 12 is located at initial position.When needing to clean condensing pipe 11, reversing valve 2 switches condenser body 1 to cleaning state, in this state, brush 12 is slid from initial position to the other end under the action of reverse water flow, to ensure effectively removing dirt on the inner wall of condensing pipe.

[0032] That is, by the switching of reversing valve, the switching of water flow movement direction is realized, under the action of water flow, brush 12 is pushed to move along the extension direction of condensing pipe 11, to realize the cleaning of the inner wall of condensing pipe body 11 by brush 12, to achieve self-cleaning purpose, can reduce pollution and blockage, effectively prolong the service life of condenser, and without disassembling condenser body, time and effort are saved.

[0033] In a feasible embodiment of the utility model, reversing valve 2 can adopt four-way reversing valve, and reversing valve 2 has first interface 21, second interface 22, third interface 23 and fourth interface 24, first interface 21 is connected with circulating water pump 3, and circulating water pump 3 is used to provide the water flow power required by condenser, to ensure that water flow circulates in condenser.Second interface 22 is connected with cooling tower 4, and cooling tower 4 is used to cool hot water backflowing from condenser, so that it can be used again.

[0034] In normal operating state, one end of third interface 23 is communicated with first interface 21, and the other end of third interface 23 is communicated with the water inlet of condenser body 1, so that the water flow provided by circulating water pump 3 can enter condenser body 1 through third interface 23.One end of fourth interface 24 is communicated with the backwater outlet of condenser body 1, and the other end of fourth interface 24 is communicated with second interface 22, and hot water after heat exchange in condenser body 1 can flow back to cooling tower for cooling through fourth interface 24.

[0035] In the cleaning state, one end of the fourth interface 24 is in communication with the first interface 21, and the other end of the fourth interface 24 is in communication with the water inlet of the condenser body 1, so that the water flow provided by the circulating water pump 3 enters the condenser body 1 through the fourth interface 24, but the direction of the water flow entering the condenser body 1 is opposite to that before, which helps to push the pipe brush 12 to move at the other end of the condensing pipe 11 to clean. One end of the third interface 23 is in communication with the water outlet of the condenser body 1, and the other end of the third interface 23 is in communication with the second interface 22.

In cleaning state, sewage during cleaning still flows to cooling tower 4 through the corresponding passage of reversing valve 2.

[0039] Therefore, through the setting of second pipeline 6, stable and reliable connection between cooling tower 4 and reversing valve 2 is realized, and smooth transmission of cooling water is ensured.
