[0019] 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.

[0020] See also Figures 1 to 3, an embodiment provided by the present utility model: a heat exchanger with stable structure, including a frame body 1 and a heat exchanger main body arranged inside the frame body 1. The frame body 1 is formed into a frame shape by surrounding with four wire drawing plates and fixed by welding. Tube plates 2 are installed at both the front and rear ends of the frame body 1. Angle irons 3 are arranged at the outer corner positions of the frame body 1. The angle irons 3 are respectively fixedly connected to two adjacent end faces of the two frame bodies 1. The angle irons 3 can cover and block the blanks at the corners of the frame body 1, preventing the transportation workers from directly contacting the blanks at the corners during transportation and reducing potential safety hazards. The angle irons 3 can also improve the connection strength of two adjacent wire drawing plates, enhancing the overall connection stability of the heat exchanger. Triangular plates 4 are arranged at the connection positions between the frame body 1 and the tube plates 2 and at the four corner positions. The triangular plates 4 are respectively fixedly connected to the frame body 1 and the tube plate 3, further enhancing the overall connection strength of the heat exchanger, preventing loosening and gaps at the equipment connection points caused by large swings or collisions of the equipment during transportation, ensuring the heat exchange effect, and extending the service life.

[0021] The insulation frame is formed by surrounding and fitting four insulation plates, and the insulation frame is fixedly connected to the corresponding side tube plate by screws.

[0022] The heat exchanger main body includes a plurality of heat exchange tubes 7, a plurality of elbows 8 and a main pipe 9. The two ends of the heat exchange tube 4 respectively penetrate through the two tube plates 3, and the heat exchange tube is fixedly installed with the two tube plates. This structure forms a stable connection structure between the heat exchanger main body and the frame body 1. Two adjacent and close heat exchange tubes 7 are connected to the two ends of the elbow 8 at the corresponding ends and are communicated. The plurality of heat exchange tubes 7 are connected by a plurality of elbows 8 to form a circuitously arranged heat exchange pipeline.

The main pipe 9 is communicated with the heat exchange pipeline. The main pipe 9 is in a "C" shape, and the main pipe 9 penetrates through the heat preservation cotton board 6 and extends to the outside. Among them, the main pipe 9 is located between the heat preservation frame 5 and the heat preservation cover plate 6. This structure can reduce the influence of external conditions on the heat exchange of the main pipe 9 and maintain the optimal heat exchange effect. Moreover, the heat preservation frame 5 and the heat preservation cover plate 6 can protect the elbows 8 on the heat exchanger body 2, preventing damage to the heat exchanger body 2 caused by collision.

[0024] When this embodiment works, the low-temperature liquid flows in from the input end of the main pipe 9 and flows through the heat exchange tube path composed of the heat exchange tubes 7 and the elbows 8. The high-temperature air flow blows towards the heat exchange tubes 7 from the front side and blows out from the rear side. The high-temperature air flow contacts the plurality of heat exchange tubes 7. The high temperature is transferred to the heat exchange tubes 7 and then conducts heat to the liquid. The air flow is cooled and blows out from the rear side, and the liquid is heated and finally flows out from the output end of the main pipe 9. The air flow and the liquid achieve the heat exchange effect.

[0025] Aluminum silicate insulation cotton is filled in the insulation cover plate 6. The above is an example of one embodiment, and does not limit the insulation cover plate 6 to be made of other materials.

[0026] The two ends of the main pipe 9 are provided with flanges 10, and the two flanges 10 are mainly used to fix the heat exchanger to the equipment.

[0027] The heat exchange tube 7 is a fin heat exchange tube. The above is an example of one embodiment and does not limit the implementation methods of other heat exchange tubes.

[0028] An elbow sealing cover 11 is also provided at the rear end of the frame 1, and the elbow sealing cover 11 is fixedly connected to the tube sheet 3 on the corresponding side by screws, so as to protect the elbow 8 on the heat exchanger body 2, prevent the heat exchanger body 2 from being damaged due to collision, and reduce the influence of external conditions on the heat exchange of the main pipe 9, thereby maintaining the optimal heat exchange effect.

[0029] A roller 12 is provided at the bottom of the frame 1 , and the roller 12 is rotatably connected to the frame 1 , and the heat exchanger can be transported and transferred via the roller 12 .
