Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a cooling-heating type heat source tower disclosed in an embodiment of the present application is composed of a tower body 11, an input chamber 12, an output chamber 13, an airflow input end 14, an airflow output end 15, heat exchange pipes 16, scrapers 17, a driving device 18, and the like, wherein the input chamber 12 and the output chamber 13 are respectively disposed at two ends of the tower body 11 and are used for connecting with external devices, and driving media of the external devices flow in the heat exchange pipes 16, and the heat exchange pipes 16 are uniformly distributed in the tower body 11 and are respectively connected with the input chamber 12 and the output chamber 13.

In some possible implementations, heat exchange tubes 16 are arranged in a matrix of MxN, both M and N being natural numbers greater than zero.

The gas flow input end 14 and the gas flow output end 15 are both arranged on the tower body 11, the gas flow input end 14 is used for enabling gas outside the tower body 11 to flow into the tower body 11, and the gas flow output end 15 is used for enabling gas inside the tower body 11 to flow out.

The scraper 17 is located the tower body 11, has seted up a plurality of through-holes 171 on the scraper 17, and the quantity and the arrangement of through-hole 171 all are the same with heat transfer pipeline 16 to, each heat transfer pipeline 16 all passes a through-hole 171 on the scraper 17, and like this, when scraper 17 reciprocating motion in the tower body 11, just can get rid of the comdenstion water or the frost on the heat transfer pipeline 16.

The power for the reciprocating movement of the scrapers 17 is provided by a drive unit 18, and the drive unit 18 is provided on the tower 11.

On the whole, the mechanical removal method is suitable for a large-scale cold and hot heat source tower, because the heat exchange pipelines 16 in the heat source tower are large in number, the removal difficulty is high, the time consumption of the methods of spraying or melting is long, extra energy is consumed, and the consumption is also an extra expenditure. The mechanical removal mode can effectively reduce the operation cost of the large-scale cold and hot type heat source tower and improve the economic benefit of operation.
