In other words, in the fixing structure 30 of the fourth embodiment, the fixing structure 30 is disposed around the insertion-plate-type heat exchanger 100, i.e., the top end surface, the bottom end surface, the left side surface, and the right side surface.

The side plate 31 and the end plate 32 are not limited by being perpendicular to each other. Alternatively, an acute angle or an obtuse angle can be defined between the side plate 31 and the end plate 32, which is not limited herein.

Since the plurality of heat exchanger tubes 20 extends along an axis of the end plate 32, the side plate 31 is perpendicular to the plurality of heat exchanger tubes 20 along an extending direction of each of the plurality of heat exchanger tubes 20. Therefore, the side plate 31 is required to be fixedly connected to the side surface of the insertion-plate-type heat exchanger 100, and the plurality of heat exchanger tubes 20 are required to be inserted into the side plate 31, such that each of the plurality of heat exchanger tubes 20 can be further fixed.

Referring to FIGS. 6 to 14, the fixing structure 30 is located on the side surface of the insertion-plate-type heat exchanger 100. The fixing structure 30 includes the side plate 31. The side plate 31 is connected to the side surface of the insertion-plate-type heat exchanger 100. The side plate 31 is provided with a plurality of inserting holes 311 corresponding to the plurality of heat exchanger tubes 20. The plurality of heat exchanger tubes 20 are inserted into the plurality of inserting holes 311. When the side plate 31 is installed on the side surface of the insertion-plate-type heat exchanger 100, the plurality of heat exchanger tubes 20 are inserted into the plurality of inserting holes 311 and fixedly connected to the side plate 31 by the plurality of inserting holes 311, thereby fixing the plurality of heat exchanger tubes 20, and preventing displacement and friction between the plurality of heat exchanger tubes 20 and the plurality of insertion plates 10.

Methods of disposing the plurality of inserting holes 311 on the side plate 31 are diverse. For example, the side plate 31 is provided with a first edge portion 312.

It is conducive to snapping and positioning the plurality of heat exchanger tubes 20 and reducing a friction in a mounting process. It is convenient to assemble the insertion plates 10 and the heat exchanger tubes 20.

In particular, when two or more rows of the plurality of inserting holes 311 are disposed on the side plate 31, the plurality of inserting holes 311 pass through the first edge portion 312 or the second edge portion 313 to define the opening 3111. In order to facilitate inserting the plurality of heat exchanger tubes 20, sizes of at least two of plurality of inserting holes 311 are different along a direction of each of the plurality of heat exchanger tubes 20 inserted into one of the plurality of inserting holes 311.
