Condenser, air conditioner outdoor unit, and air-conditioning system

Abstract

A condenser, an air conditioner outdoor unit, and an air-conditioning system. The condenser includes at least one row of heat exchange tubes and a plurality of fins arranged along the heat exchange tubes, where any fin is provided with at least one column of through holes, which correspond to the number of rows of the heat exchange tubes, for the heat exchange tubes to pass through; the fins are evenly divided, in the width direction, into at least one basic unit corresponding to the number of rows of the heat exchange tubes; the width of any basic unit is greater than 18.2 mm; and the center distance between two adjacent through holes from among any column of through holes is less than 21 mm. As a result, the heat exchange efficiency can be improved, and the energy efficiency can also be improved.

         13 . The condenser according to  claim 11 , wherein a distance between two adjacent fins is 1.2-1.4 mm. 
     
     
         14 . The condenser according to  claim 11 , wherein two adjacent columns of perforations are staggered; a first spacing between the center of a perforation on the fin at a bottom end and a bottom edge of the fin is smaller than a second spacing between the center of a perforation at a top end in the column of perforations where the perforation is located and a top edge of the fin. 
     
     
         15 . The condenser according to  claim 14 , wherein the first spacing is ¼ of the center-to-center distance between two adjacent perforations in any column of the perforations, and the second spacing is ¾ of the center-to-center distance between two adjacent perforations in any column of the perforations. 
     
     
         16 . The condenser according to  claim 11 , wherein both ends of the heat exchange pipes are respectively connected with a pipe plate, the pipe plates are provided with holes corresponding to the heat exchange pipes, and at least one of two adjacent holes on any of the pipe plates is configured as a flanged hole. 
     
     
         17 .
