However, these cooling methods have problems such as high energy consumption, low efficiency, and high maintenance costs. At the same time, in winter when the temperature is low, the oil needs to be heated in each pump station, especially the lubricating oil, to maintain the fluidity of the lubricating oil. The heating system mostly uses electric heating or steam heating, which also has the disadvantages of high energy consumption, high cost and complex structure.

[0022] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes the implementation of the present invention based on its overall structure.

[0024] Reference Figure 1 As shown, the embodiment of the present application provides a cooling and heating circulation system for an aluminum foil rolling mill, comprising:

[0025] Pump unit 1;

[0026] a first heat exchanger 2 in communication with the pump unit 1, the first heat exchanger 2 being in communication with the pump unit 1 via a first pipe 3, for cooling the pump unit 1;

[0027] a second heat exchanger 4 in communication with the first heat exchanger 2, wherein the second heat exchanger 4 is in communication with the first heat exchanger 2 via a second pipe 5;

[0028] The pump station 6 is connected to the second heat exchanger 4 and is connected to the second heat exchanger 4 through a third pipeline 7 for circulating the temperature conversion liquid.

[0029] according to Figure 1 , those skilled in the art can set up a structure in which the pump unit 1 is connected to the pump station 6, wherein a first heat exchanger 2 and a second heat exchanger 4 are provided between the pump unit 1 and the pump station 6, so that the temperature conversion liquid between the pump unit 1 and the pump station 6 can be circulated.

[0030] Specifically, those skilled in the art may set a first pipe 3 on the pump unit 1. It is understandable that the first pipe 3 is installed between the pump unit 1 and the first heat exchanger 2, and both ends of the first pipe 3 are connected to the pump unit 1 and the first heat exchanger 2 respectively.

[0031] With the above structure, the first heat exchanger 2 is connected to the pump unit 1 through the first pipe 3, and the temperature conversion liquid in the pump unit 1 can be introduced into the first heat exchanger 2 for cooling, thereby completing the adjustment of the temperature in the pump unit 1.

[0032] Furthermore, those skilled in the art may continue to configure the first heat exchanger 2 to be connected to the second heat exchanger 4 via a second pipe 5 , and the second heat exchanger 4 to be connected to the pump station 6 via a third pipe 7 .

[0033] With the above structure, those skilled in the art can circulate the temperature conversion liquid between the first heat exchanger 2 and the second heat exchanger 4 and between the second heat exchanger and the pump station 6 .

[0034] It can be understood that in the above structure, the technicians in this field set up the first heat exchanger 2 and the second heat exchanger 4, and the first heat exchanger 2 and the second heat exchanger 4 remain connected, so as to significantly improve the temperature regulation effect of the temperature conversion liquid in the circulation system.

[0035] In the above embodiment, those skilled in the art arrange for the pump station 6 to be connected to the second heat exchanger 4 via a third pipe 7 , so that the temperature in the pump station 6 can be controlled and adjusted.

[0036] To sum up, those skilled in the art arrange the first pipe 3 to be installed between the pump unit 1 and the first heat exchanger 2, and the two ends of the first pipe 3 are respectively connected to the pump unit 1 and the first heat exchanger 2, the second heat exchanger 4 is connected to the pump station 6 through the third pipe 7, and the first heat exchanger 2 and the second heat exchanger 4 are connected through the second pipe 5, so that a complete temperature circulation system can be formed to achieve temperature regulation.

[0037] It is understandable that the above structure does not use a cooling tower or cooler to regulate temperature through water or air circulation, thereby significantly reducing the cost of temperature control in the aluminum foil rolling mill. Furthermore, the provision of the first heat exchanger 2 and the second heat exchanger 4 can reduce the footprint of the hot and cold circulation system, thereby making the installation of the hot and cold circulation system more convenient.

[0038] In an optional embodiment, preferably, the pump unit 1 is arranged adjacent to the pump station 6 , and the first heat exchanger 2 and the second heat exchanger 4 are arranged at intervals between the pump unit 1 and the pump station 6 .

[0039] With the above structure, those skilled in the art can install the first heat exchanger 2 and the second heat exchanger 4 between the pump unit 1 and the pump station 6, thereby completing a reasonable arrangement of the installation space of the first heat exchanger 2 and the second heat exchanger 4.

[0040] In the above embodiment, those skilled in the art install the first pipe 3, the second pipe 5, and the third pipe 7 to connect the pump unit 1, the first heat exchanger 2, the second heat exchanger 4, and the pump station 6. In this embodiment, the first heat exchanger 2 and the second heat exchanger 4 are installed between the pump unit 1 and the pump station 6, so that the distribution of the first pipe 3, the second pipe 5, and the third pipe 7 does not interfere with each other, thereby improving the safety of the hot and cold circulation system during use.

[0041] In the above embodiment, the first heat exchanger 2 and the second heat exchanger 4 are installed between the pump unit 1 and the pump station 6, thereby preventing interference between the first pipeline 3, the second pipeline 5, and the third pipeline 7. Preferably, the pump unit 1 and the pump station 6, as well as the first heat exchanger 2 and the second heat exchanger 4, are evenly spaced, thereby further improving space utilization between the first heat exchanger 2 and the second heat exchanger 4.

[0042] It can be understood that the pump unit 1 and the pump station 6 and the first heat exchanger 2 and the second heat exchanger 4 are arranged to maintain a uniform interval, so that the transportation of the temperature conversion liquid between the first pipeline 3, the second pipeline 5 and the third pipeline 7 can be more stable, and the temperature control of the temperature conversion liquid can be more accurate.

[0043] In one embodiment, preferably, the temperature conversion fluid can be circulating oil. In this embodiment, those skilled in the art set the temperature conversion fluid to circulating oil, which can effectively avoid pipeline blockage caused by impurities.

[0044] Understandably, temperature control using circulating water is often performed. Long-term use of circulating water can lead to scaling and clogging of heat exchangers and pipes, rendering the hot and cold circulation system ineffective. Using circulating oil completely avoids this, improving the stability of the hot and cold circulation system.

[0045] In an optional embodiment, preferably, at least two first pipes 3 are provided between the pump unit 1 and the first heat exchanger 2. Preferably, at least two third pipes 7 are provided between the pump station 1 and the second heat exchanger 4. By providing at least two first pipes 3 and at least two third pipes 7, the temperature conversion fluid can be continuously circulated.

[0046] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Some industry standards or slightly modified implementations based on customized methods or implementations described in the embodiments can also achieve the same, equivalent, or similar implementation effects as the above embodiments, or predictable implementation effects after modification. Examples that apply these modified or modified data acquisition, processing, output, judgment methods, etc. can still fall within the scope of optional implementation schemes of this application.

[0047] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
