[0027] The following is in conjunction with the appendix Figure 1-10 The present invention will be further described below.

[0028] In order to solve the problems existing in the background art, this application proposes the following technical solution: a heat exchanger for lubricating oil processing, including a heat exchange box 1, the top and bottom of the heat exchange box 1 are detachably and fixedly connected to a top plate and a bottom plate, the top and bottom of the heat exchange box 1 are respectively fixedly connected to a first feed pipe 2 and a first discharge pipe 3 (which are respectively fixedly connected to the top plate and the bottom plate), and the two sides of the heat exchange box 1 are respectively fixedly connected to a second feed pipe 4 and a second discharge pipe 5.

[0029] The heat exchange box 1 has a first fixing plate 6 and a second fixing plate 7 fixedly connected to its inner top and bottom, respectively. The first fixing plate 6 has multiple sets of first heat exchange tubes 9, and the second fixing plate 7 has multiple sets of second heat exchange tubes 10. Both the first heat exchange tubes 9 and the second heat exchange tubes 10 are aluminum tubes. The first heat exchange tubes 9 and the second heat exchange tubes 10 are interlocked with each other, as follows: the bottom of the first heat exchange tube 9 is fixedly connected with a protruding tube 21, and the top of the second heat exchange tube 10 is provided with a notch 22, which can be inserted into the notch 22 to achieve the insertion and fixation.

[0030] In a further design, both the first heat exchange tube 9 and the second heat exchange tube 10 are provided with through holes 14 on the outside. Both the first heat exchange tube 9 and the second heat exchange tube 10 are fixedly connected with sealing rings 13, which serve as seals. Both the first fixing plate 6 and the second fixing plate 7 are fixedly connected with fixing brackets 11. The fixing brackets 11 are fixedly connected with side plates 12. The fixing brackets 11 are provided with abutting components, which are used to abut and fix the first heat exchange tube 9 and the second heat exchange tube 10.

[0031] Multiple sets of sealing sleeves 8 are fixedly connected to the outside of the first fixing plate 6 and the second fixing plate 7. The sealing sleeves 8 are sleeved on the outside of the first heat exchange tube 9 and the second heat exchange tube 10. The sealing sleeves 8 are provided to increase the sealing performance between the first heat exchange tube 9 and the second heat exchange tube 10 and the first fixing plate 6 and the second fixing plate 7, respectively.

[0032] In this embodiment, the abutment assembly includes a threaded sleeve 16, an abutment post 18 fixedly connected to the bottom of the threaded sleeve 16, and an abutment plate 19 fixedly connected to the bottom of the abutment post 18. A rotating block 17 is fixedly connected to the top of the threaded sleeve 16. Multiple sets of threaded rings 20 are fixedly connected to the fixing frame 11. Multiple sets of through holes are provided on the fixing frame 11. The through holes are concentrically arranged with the threaded rings 20. The first heat exchange tube 9 and the second heat exchange tube 10 are inserted into the corresponding first fixing plate 6 and second fixing plate 7, and the convex tube 21 is inserted into the recess 22. Then, through the connection between the threaded sleeve 16 and the threaded ring 20, the abutment plate 19 abuts against the first heat exchange tube 9 and the second heat exchange tube 10 to fix them.

[0033] In addition, it also includes a limiting plate 23, which has multiple sets of limiting ports 24. The limiting ports 24 cooperate with the rotating block 17. Multiple sets of threaded columns 15 are fixedly connected to the fixing frame 11. Nuts 25 are connected to the external threads of the threaded columns 15. The cooperation between the nuts 25 and the threaded columns 15 is used to fix the limiting plate 23.

[0034] The usage method of this embodiment is as follows:

[0035] Coolant is transported to heat exchange box 1 through first feed pipe 2, enters first heat exchange pipe 9 and second heat exchange pipe 10 through through hole 14 on first heat exchange pipe 9, is discharged through through through hole 14 on second heat exchange pipe 10, and finally discharged through first discharge pipe 3.

[0036] Subsequently, the lubricating oil is transported to the heat exchange box 1 through the second feed pipe 4 and discharged through the second discharge pipe 5. After entering the heat exchange box 1, the lubricating oil exchanges heat with the first heat exchange tube 9 and the second heat exchange tube 10, thereby reducing the temperature of the lubricating oil.

[0037] After long-term use, if it is necessary to clean the first heat exchange tube 9 and the second heat exchange tube 10, simply remove the top cover and bottom cover on the heat exchange box 1, turn the nut 25 to remove the nut 25, then remove the limiting plate 23, and then turn the nut 25 on the first heat exchange tube 9 and the second heat exchange tube 10 that need to be replaced or cleaned so that the contact plate 19 no longer contacts the first heat exchange tube 9 or the second heat exchange tube 10. Then, pull out the first heat exchange tube 9 and the second heat exchange tube 10.

[0038] In this way, the first heat exchange tube 9 and the second heat exchange tube 10 can be easily replaced or cleaned.

[0039] During installation, the first heat exchange tube 9 and the second heat exchange tube 10 are inserted into the corresponding first fixing plate 6 and second fixing plate 7, and the convex tube 21 is inserted into the recess 22. Then, through the connection between the threaded sleeve 16 and the threaded ring 20, the abutment plate 19 abuts against the first heat exchange tube 9 and the second heat exchange tube 10 to fix them.
