Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3, an air cooler tube bundle fixing device, comprising an upper fixer 1 and a lower fixer 4, a first side connecting plate 2 is installed on the outer side of the lower end of the upper fixer 1, upper connecting plates 3 are installed on both sides of the upper end of the fixer 1, a second side connecting plate 5 is installed on the outer side of the upper end of the lower fixer 4, and lower connecting plates 6 are installed on both sides of the lower end of the lower fixer 4, a plurality of semicircular grooves 7 are opened on the opposite sides of the upper fixer 1 and the lower fixer 4, a first bolt 8 is connected in the hole of the first side connecting plate 2, and a second bolt 9 is connected in the hole of the lower connecting plate 6; the first side connecting plate 2 and the second side connecting plate 5 are both provided with threaded holes of equal size, and the upper connecting plate 3 and the lower connecting plate 6 are also provided with threaded holes of equal size.

[0019] Furthermore, a telescopic rod 10 is installed in the semicircular groove 7, one end of the telescopic rod 10 is movably connected with a clamping piece 11, one end of the clamping piece 11 is installed with a rubber pad 12, and the other end of the telescopic rod 10 is installed with a spring 13, and a fixing groove 14 is installed outside the spring 13;

[0020] Furthermore, the role of the rubber pad 12 is to enhance the constraint of the clamping piece 11 on the tube bundle, making it more secure. One end of the telescopic rod 10 connected to the spring 13 moves in the fixed groove 14 to achieve length change. The lower end of the telescopic rod 10 is hinged to the clamping piece 11, which facilitates the clamping piece 11 to clamp the tube bundle at a better angle.

[0021] Furthermore, a slot 15 is provided on the outer side of the telescopic rod 10, a block 16 is movably connected in the slot 15, and a sliding slot 17 is installed on the outer side of the block 16; the block 16 moves in the sliding slot 17, and the block 16 is inserted into the slot 15, and the telescopic rod 10 is fixed.

[0022] Further, one end of the first bolt 8 penetrates the first side connecting plate 2 and the second side connecting plate 5 to connect the two, and one end of the second bolt 9 penetrates the lower connecting plate 6 and the upper connecting plate 3 to connect the two;

[0023] Furthermore, the first bolt 8 connects the two side plates, so that the upper fixer 1 and the lower fixer 4 are spliced ​​into a set of fixing devices, and the second bolt 9 fixes the upper connecting plate 3 and the lower connecting plate 6, so that multiple sets of fixing devices can be combined together to achieve free matching.

[0024] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0025] Embodiment: First, insert the first bolt 8 into the first side connecting plate 2, and then connect the second side connecting plate 5, so that the upper fixer 1 and the lower fixer 4 form a complete fixing device. At this time, the first bolt 8 cannot be completely tightened. Then, place the tube bundle into the upper and lower semicircular grooves 7. According to the size of the tube bundle, adjust the length of the telescopic rod 10. The spring 13 connected to the tail end of the telescopic rod 10 is stressed and compressed into the fixing groove 14. In the pre-fixation, it can better help the clamping piece 11 to be fixed, so that the rubber pad 12 at one end of the clamping piece 11 just contacts the outer surface of the tube bundle. Because the telescopic rod 10 and the clamping piece 11 are hingedly connected, the clamping piece 11 can better fit the outer surface of the tube bundle. Then push the block 16 to slide in the sliding groove 17 until the block 16 Fully insert it into the slot 15 opened on the outside of the telescopic rod 10, fix the telescopic rod 10 and the final fixation of the tube bundle is completed; when the fixation of one end of the tube bundle is completed, tighten the first bolt 8 again to make the upper fixer 1 and the lower fixer 2 completely combined, and install another set of upper and lower fixers at the other end of the tube bundle to finally make both ends of the tube bundle uniformly fixed, so that a set of fixed tube bundles is obtained. When it is necessary to install multiple sets of tube bundles according to actual conditions, it is only necessary to connect the upper connecting plate 3 of one set of fixers to the lower connecting plate 6 of another set of fixers, and use the second bolt 9 to fix them. Multiple sets are stacked to complete the splicing of multiple sets of tube bundles; when a single tube bundle needs to be replaced or repaired, it is only necessary to open the clamping piece 11 that fixes it separately to complete the replacement, which is simple and convenient.
