Problems solved by technology

However, this structure still has the following technical problems: no matter which side the fan is placed on the heat exchanger 10, there is an uneven distribution of the wind field in the height direction of the heat exchanger 10
Therefore, the unevenness of the wind field will cause the heat exchange capacity of the heat exchanger 10 to be unbalanced and affect the heat exchange efficiency.

Abstract

The invention discloses a heat exchanger, comprising at least two rows of heat exchange tubes formed by bending general heat exchange tube rows; in the height direction of the heat exchanger, the numbers of transverse rows of the heat exchange tubes which have at least two corresponding heat exchange positions are different, and a fan can be mounted at a position where more rows of corresponding heat exchange tubes are arranged, thereby ensuring that a position where more rows of heat exchange tubes are arranged corresponds to a wind field with higher wind speed and more airflow, and a position where few rows of heat exchange tubes are arranged corresponds to a wind field with lower wind speed and less airflow, so that the arrangement of heat exchange tubes in the heat exchanger can be adapted to corresponding working environment. The heat exchanger provided by the invention has the advantages of equalizing the heat exchange capability of the heat exchanger and improving the heat exchange efficiency of the heat exchanger.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchanger. Background technique [0002] Heat exchanger is a device that realizes heat exchange between hot medium and cold medium, and is widely used in HVAC and other fields. [0003] The heat exchanger usually includes two headers arranged in parallel, and there are a plurality of heat exchange tubes arranged substantially in parallel between the headers to form a row of heat exchange tubes. The two ends of the heat exchange tube are respectively connected to the two headers on both sides, and the heat exchange medium enters the heat exchange tube from the header on one side, and then flows out from the header on the other side, thereby realizing heat exchange. [0004] It can be seen from the above working principle that factors such as the flow rate of the heat exchange medium and the heat exchange stroke (the axial length of the heat exchange tube) directly af...
