Further, the heat exchange bobbin carriage being in top is communicated with by expansion joint with adjacent heat transferring medium pipeline enclosure.
Further, described expansion joint comprises upper and lower rigidity installation portion and the elastic joint part between upper and lower rigidity installation portion, described upper rigidity installation portion is connected with heat transferring medium pipeline, described lower rigidity installation portion is connected with the heat exchange bobbin carriage at top, described elastic joint part comprises the cambered outwards arc sections of upper and lower flat part and centre, and described upper and lower flat part is connected with upper and lower rigidity installation portion respectively by bolt.
Further, described expansion joint also comprises sealing gasket and the support portion for supporting sealing gasket, described sealing gasket is positioned at inside elastic joint part, described sealing gasket contacts with the edge up and down of arc sections respectively near the two ends up and down of the side of arc sections, and described sealing gasket is supported by support portion away from the side of arc sections.
The beneficial effects of the utility model: air heat exchanger of the present utility model, comprise the heat exchange bobbin carriage of multiple vertical layout, the heat exchanger tube with inside and outside three-dimensional rib plate is provided with in described each heat exchange bobbin carriage, connected by pipeline between adjacent heat exchange case, be communicated with by being communicated with case between two heat exchange bobbin carriages of a heat exchange bobbin carriage separately, described pipeline is respectively equipped with valve with being communicated with on case.In the heat exchange box that can enter requirement according to state modulator thermals source such as the flow of thermal source, heats, preheating is carried out to air, enable the preset temperature that air reaches required.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of expansion joint.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the air heat exchanger of the present embodiment, comprise the heat exchange bobbin carriage 1,2,3,4 of multiple vertical layout, the heat exchanger tube 11,21,31,41 with inside and outside three-dimensional rib plate is provided with, adjacent heat exchange case 1,2 in described each heat exchange bobbin carriage 1,2,3,4; 2,3; 3, connected by pipeline 5,6,7 between 4, it is characterized in that: two heat exchange bobbin carriages 1,3 of a heat exchange bobbin carriage separately; 2, be communicated with by being communicated with case 8,9 between 4, described pipeline 5,6,7 is respectively equipped with valve 51,61,71,81,91 with being communicated with on case 8,9.Control corresponding valve, the heat transferring medium of air can be made only by heat exchange bobbin carriage 1 and heat exchange bobbin carriage 3, or heat exchange bobbin carriage 1,2 and 3, or heat exchange bobbin carriage 1,2 and 4 etc., the heat of heat transferring medium fully utilizes by flow, temperature etc. according to heat transferring medium, ensure that air can reach the temperature of setting after heat exchanger, and ensure heat exchange efficiency.
As the further improvement of technique scheme, be in the heat exchange bobbin carriage 1 at top and be communicated with by expansion joint 10 with between adjacent heat transferring medium pipeline 20.Air preheater is connected around property with the pipeline enclosure of heat transferring medium, compensates substitution device and to expand with heat and contract with cold the elastic deformation brought.
As the further improvement of technique scheme, described expansion joint 10 comprises upper and lower rigidity installation portion 101,102 and the elastic joint part 103 between upper and lower rigidity installation portion 101,102, described upper rigidity installation portion 101 is connected with heat transferring medium pipeline 20, described lower rigidity installation portion 102 is connected with the heat exchange bobbin carriage 1 at top, described elastic joint part 103 comprises the cambered outwards arc sections 106 of upper and lower flat part 104,105 and centre, and described upper and lower flat part 104,105 is connected with upper and lower rigidity installation portion 101,102 respectively by bolt.When air heat exchanger expand with heat and contract with cold produce distortion time, elastic joint part 103 can the change in displacement of make-up air preheater or flue, and elastic joint part 3 has arc sections 106, and the displacement that this arc sections 106 makes it possible to compensate is larger.
