[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0021] See also Figure 1-4The utility model provides a technical solution: a heat exchanger system, including a heat exchanger 1 and a mounting system 2 connected to the heat exchanger 1, the heat exchanger 1 includes a plurality of separate heat exchanger units, and these separate heat exchanger units are stacked up and down and fixedly connected in sequence to form a complete heat exchanger 1, the mounting system 2 includes a connector 20 connected to the heat exchanger 1 at one end, a balance beam 21 connected to the other end of the connector 20, and a steel beam 22 fixedly connected to both ends of the balance beam 21, the steel beam 22 is pre-buried in the top of the wind tunnel The ends of the balance beam 21 are fixedly connected to the steel beam 22 by bolts. In this embodiment, the connector 20 is a lifting bolt. A fixedly connected lifting lug 10 is provided on the uppermost heat exchanger unit. The lifting lug 10 is provided with a lifting steel beam 11 fixedly connected thereto. The lifting steel beam 11 includes a lifting part 110 connected to the lifting lug 10 and an H-shaped steel 111 fixedly connected to the lifting part 110. One end of the connector 20 is fixedly connected to the H-shaped steel 111, so that one end of the connector 20 is fixedly connected to the H-shaped steel 111. 11 is fixedly connected, and the other end of the connector 20 is permanently anchored to the balance beam 21, so that the entire heat exchanger 1 is anchored to the balance beam 21 by using the connector 20, and the lowest heat exchanger unit is not connected to the bottom of the wind tunnel, so that the entire heat exchanger 1 is suspended in the heat exchange section in the wind tunnel, which can avoid structural deformation caused by temperature difference and internal cooling water. The heat exchanger 1 is permanently anchored to the balance beam 21 by using the connector 20, and the two ends of the balance beam 21 are fixedly connected to the steel beam 22 at the top of the wind tunnel. In this way, the hoisting force of the heat exchanger 1 during installation can be converted to the force of the steel beam 22, thereby completing the force conversion, and the above-mentioned anchoring connection method has a good force-bearing effect, can ensure the installation accuracy of the heat exchanger 1, and can also withstand the deformation of the heat exchanger 1 during operation, so that the entire heat exchanger 1 is suspended in the heat exchange section in the wind tunnel, which can avoid structural deformation caused by temperature difference and internal cooling water. At the same time, the large structural weight of the heat exchanger 1 itself can be sufficient to overcome the influence of windward aerodynamic resistance.

[0022] The entire heat exchanger 1 system also includes a filter module 3, which includes a plurality of filter screens 30 and a plurality of connecting frames 31. The filter screens 30 and the connecting frames 31 are fixedly installed, and all the connecting frames 31 are stacked up and down and fixedly connected in sequence to form the entire filter module 3. The filter module 3 is installed in the wind tunnel and is located in the windward position in front of the heat exchanger 1, and the upper and lower ends of the filter module 3 are respectively connected to the top and bottom of the wind tunnel. In this way, when air flows in, the filter screen 30 in the filter module 3 can effectively filter the debris in the air, thereby preventing the debris from being blown into the heat exchanger 1 and causing damage to the inside of the heat exchanger 1.

[0023] When the whole heat exchanger 1 is installed, the whole heat exchanger 1 is firstly decomposed into several heat exchanger units, and each heat exchanger unit is marked with a serial number, and then a protective frame is arranged outside each heat exchanger unit, which is convenient for both transportation and hoisting, and then hoisting is performed using a balance beam 21 according to the serial number of each heat exchanger unit. During the hoisting stage, the balance beam 21 is used as a temporary hoisting part to maintain the balance of the hoisted heat exchanger unit and prevent the sling from damaging the heat exchanger unit. A steel support platform is also provided in the wind tunnel, and several round steels are placed on the steel support platform as rolling bars. And the elevation of the roller on the steel support platform is consistent with the elevation of the roller placed on the ground outside the wind tunnel, so that when a single heat exchanger unit is moved from the roller on the ground outside the wind tunnel to the roller on the steel support platform, the single heat exchanger unit can be moved and transported by rolling the roller, which is simple to operate and has stable and efficient translation. After the heat exchanger unit is transported, the lifting sequence is designed in advance, and then the balance beam 21 is used to lift and install it in sections in sequence according to the serial number. After the lifting is completed, the top heat exchanger unit is permanently anchored to the balance beam 21 with lifting bolts.

[0024] The working principle or beneficial effect of the utility model is as follows: the heat exchanger 1 and the balance beam 21 are permanently anchored by using the connecting piece 20, and the two ends of the balance beam 21 are respectively fixedly connected to the steel beam 22 at the top of the wind tunnel, so that the entire heat exchanger 1 system is fixedly installed in the wind tunnel. This anchoring installation method has a good load-bearing effect, can ensure the installation accuracy of the entire heat exchanger 1 system, and can also withstand the deformation of the heat exchanger 1 during operation.
