Description

A multi-row parallel flow heat exchanger

technical field

The utility model belongs to the technical field of refrigeration and air conditioning equipment, in particular to a multi-row parallel flow heat exchanger.

Background technique

The heat exchanger is an important part of heat conversion in air conditioning or refrigeration equipment, and its quality directly affects the cooling effect. Double-row parallel flow heat exchangers have been used in some products (such as automobile condensers). Aluminum sheet, the refrigerant flows in through the header, then flows into the other header through a set of flat tubes, and then flows out. The double-row parallel flow heat exchanger is a new structure that replaces the original copper tube-fin heat exchanger and tube-belt heat exchanger. Compared with the original copper tube-fin heat exchanger, the heat exchange capacity has increased by nearly 30 %, and has better anti-seismic performance. However, an important reason why it has not been widely used in other refrigeration or air-conditioning equipment is that the width of flat tubes with multiple microchannels is limited by the manufacturing materials and technical level, and it is difficult to increase as required, resulting in single-row heat pipe heat exchangers that can only pass through The increase of the plane area increases the heat exchange area, and the size of the single-row heat exchanger will be large and flat. Therefore, to improve the heat exchange capacity, it can only be achieved by increasing the number of heat exchangers. However, multiple heat exchangers not only increase the difficulty of installation, but also complicate the structure. For the heat exchangers that share the air duct, it is also necessary to require that the multiple heat exchangers cannot be misplaced to avoid the increase of wind resistance, which is important in assembly. The process is almost uncontrollable.
