It is connected through a screw thread, the fixed plate, the lockplate and the welded plate is fixed.
Preferably, the fixed plate is integrally formed with the connecting plate.
Preferably, the fixed plate with the connecting plate by being welded and fixed.
Preferably, the fastener is bolt (stud) and nut.
Preferably, the connection component is made of steel plate.
Preferably, the support bar is equipped with multiple through-holes, is used to support the heat-transfer pipe of C-shaped tube bundle heat exchanger.
Compared with prior art, the advantage of the utility model is：

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
It is as shown in Figure 1 the fixed structure chart of the C-shaped pipes beam heat exchanger supports item of the utility model.Fixed structure includes
Support element 9, connection component and support bar 4；The side of connection component is fixed on support element 9, and the other side of connection component is equipped with
The end of connecting plate 3, support bar 4 is threaded through in connection component, and is fixedly connected with connecting plate 3 by fastener.
Wherein, connection component preferably includes welded plate 8, lockplate 7 and fixed plate 6 successively；Fixed plate 6 and connecting plate 3
It is fixedly connected；Lockplate 7 is equipped with the groove (not shown) that can accommodate support bar end, for fixed support support bar 4；
