Preferably, the side surface of the core heat exchange tube is in a regular triangle shape.

Preferably, a supporting column is arranged in the middle of the inside of the core heat exchange tube with the side surface in a regular triangle shape.

Preferably, the core heat exchange tubes are uniformly spaced and staggered with each other to form an array.

Preferably, the fixing plate is arranged between the arrays formed by the core heat exchange tubes in a staggered manner.

Preferably, a certain distance is reserved between the side plates fixedly arranged on the two end plates and the core heat exchange tube.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the heat exchange device has the advantages that the core heat exchange tubes with the regular triangle-shaped side surfaces are uniformly spaced and are mutually staggered to form an array, so that the area of a heat exchange channel is increased, the structure is compact, the occupied area is small, the installation is convenient, the design is flexible, the number of the core heat exchange tubes can be automatically installed according to the requirement, and the investment cost is saved;

2. the utility model discloses still be provided with the fixed plate simultaneously, the side is triangle-shaped's core heat exchange tube stability itself is stronger, and the fixed plate can further improve the stability of core heat exchange tube, and heat transfer passageway constitutes by the side-in triangle-shaped's core heat exchange tube simultaneously, is difficult for forming the dirt, and the scale removal cycle length is long, washs the convenience.
