How should the rectangular arrangement of heat exchange tubes be handled?

Is it possible to arrange the heat exchange tubes in a rectangular pattern, and if so, how should it be done? Thank you!
The standards specify only triangular and square arrangements; rectangular arrangements are not specified. The fact that it isn’t specified in the standards doesn’t mean it’s impossible, but it makes the calculations more complicated.
The heat exchange tubes are arranged in equilateral triangles and squares to ensure that the spacing between the tubes is uniform, thereby achieving efficient heat transfer. If a rectangular arrangement is used, the spacing will vary, and the heat transfer efficiency will surely be poor.
Sure. For example, in large air heat exchangers, the heat exchange tubes can be of DN250 diameter, and the enclosure can also take the form of a rectangular tube box.
The heat exchange tubes are arranged in a rectangular pattern, resulting in a non-compact structure, uneven heating, and unstable flow rates, which give rise to a series of problems. If the requirements are rather casual, it can be used as a makeshift solution, but from a design perspective, it represents an unprofessional attitude!
