[0016] 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.
[0017] Example
[0018] See also Figure 1-2 The utility model provides the following technical solutions: a new energy-saving and environmentally friendly heat exchanger, including a front end shell 4, a heat exchange plate 6 and a rear end shell 7, characterized in that: the front end shell 4, the heat exchange plate 6 and the rear end shell 7 adopt a modular design, dividing the heat exchanger into several independent and fully functional modules, each module includes a hot fluid inlet 2, a hot fluid outlet 11, a cold fluid inlet 10 and a cold fluid outlet 9.
[0019] Specifically, a connecting pipe 1 is disposed on the outer surface of the front end shell 4 , and an external connecting rod 3 is disposed on the outer surface of the connecting pipe 1 .
[0020] Specifically, a heat exchange fin 6 is provided on a side of the front end housing 4 away from the external rod 3 .
[0021] Specifically, a rear end shell 7 is provided on a side of the heat exchange fin 6 away from the front end shell 4 .
[0022] Specifically, the connection between the hot fluid inlet 2 and the cold fluid inlet 10 and the front end shell 4 , and the connection between the cold fluid outlet 9 and the hot fluid outlet 11 and the rear end shell 7 are all fixed by fixing bolts 5 .
[0023] Specifically, mounting tubes 8 are provided at the upper and lower ends of the rear end housing 7 .
[0024] In this embodiment, modular design plays a key role in the new energy-saving and environmentally friendly heat exchanger of the utility model. This design allows the heat exchanger to be flexibly configured and adjusted according to different application requirements and scenarios.
[0025] First, modular design means that the heat exchanger is divided into several independent, fully functional modules, namely heat exchange units. Each heat exchange unit includes a hot fluid inlet 2, a cold fluid inlet 10, a hot fluid outlet 11 and a cold fluid outlet 9. These interfaces enable each unit to perform heat exchange operations independently. Therefore, according to actual needs, the number of heat exchange units can be increased or decreased to meet specific heat exchange requirements.
[0026] Secondly, the modular design makes the maintenance of the heat exchanger more convenient. Since each heat exchange unit is independent, when a unit fails or needs to be cleaned, only that unit needs to be operated without affecting the normal operation of other units. This design greatly reduces the difficulty and cost of maintenance and improves the reliability and service life of the heat exchanger.
[0027] In addition, modular design also helps to improve the energy efficiency of the heat exchanger. Each heat exchange unit can be independently optimized according to actual needs to achieve the best heat exchange effect. At the same time, through reasonable module combination and configuration, precise control of hot and cold fluids can be achieved, further improving energy utilization.
[0028] In the present invention, modular design is also reflected in the design of the heat exchanger fins. The use of wavy heat exchanger fins not only increases the heat exchange area and improves the heat exchange efficiency, but also enables each heat exchanger fin to be replaced and repaired as an independent module. This design further enhances the flexibility and maintainability of the heat exchanger.
[0029] Connection between heat exchange units: Each heat exchange unit has independent hot fluid inlet, cold fluid inlet, hot fluid outlet and cold fluid outlet. In modular design, these interfaces adopt standardized connection methods, such as flange connection, welding connection or quick-install connection, to ensure that each heat exchange unit can be easily and quickly combined together.
[0030] Connection between heat exchanger and pipeline: As a whole, the heat exchanger needs to be connected to the external hot fluid pipeline and cold fluid pipeline. These connection points also use standardized connection methods, such as flange connection, welding connection, etc., to ensure that the fluid can smoothly enter and leave the heat exchanger.
[0031] Connection between heat exchanger and supporting structure: In order to ensure the stability and safety of the heat exchanger, it needs to be fixed to an appropriate supporting structure. This connection can be achieved by welding, bolting or other mechanical connection methods to ensure that the heat exchanger can withstand various forces and pressures during operation.
[0032] Through the above connection methods, the modular heat exchanger can be flexibly combined and expanded to adapt to different application requirements and scenarios. At the same time, this design method is also convenient for maintenance and replacement of parts, reducing maintenance costs and difficulties, and improving the reliability and service life of the heat exchanger.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
