Description

Technical Field

[0001] The utility model specifically relates to the technical field of uneven liquid distribution in fins, and specifically is a plate-fin heat exchanger for improving uneven liquid distribution. Background Technique

[0002] When the fin assembly in the heat exchanger conducts cyclic heat exchange through liquid, since the inside of the fin is provided with a cavity, when the liquid flows, the liquid can penetrate between multiple fins to achieve the effect of effective heat exchange of the fins. However, in use, when the fins shake, the liquid inside the fins will shift, which will cause the liquid to flow into the inside of one fin, resulting in the inability to effectively achieve the heat exchange effect inside the remaining fins.

[0003] When conducting heat exchange through fins, it is necessary to add liquid. When the liquid flows, the liquid needs to pass between multiple fins in sequence, so that the time for the liquid to fill the inner cavity is relatively long, and the inner cavity cannot be filled in a short time.

[0004] After retrieval, Chinese Patent Publication No. CN201820137127.1 discloses a plate-fin heat exchanger for improving uneven liquid distribution; it includes a shell, a partition plate, and a connecting plate. It also includes a perforated fin assembly, and the perforated fin assembly includes a heat transfer enhancement plate and an anti-sloshing plate; the long sides of the connecting plate, the heat transfer enhancement plate, and the anti-sloshing plate are regularly connected in pairs to form a serrated fin, and the fin and the partition plate form a rectangular fluid channel; multiple holes are provided on the heat transfer enhancement plate.

[0005] In the above patent, holes are opened on the heat transfer enhancement plate. When the liquid flows, after one cavity is filled, it is transmitted to the next cavity through the holes. In this way, the flow transmission efficiency of the liquid is relatively slow, and multiple cavities cannot be filled within a short time. Moreover, the holes in the above patent are arranged in the middle position of the heat transfer enhancement plate, so that the overall operation of the fins cannot be effectively guaranteed during heat exchange of the fins, resulting in a relatively low overall working efficiency of the fins.

[0006] In view of the above situation, we provide a plate-fin heat exchanger for improving uneven liquid distribution. In this device, there are a first fin, a second fin, a third fin, and a fourth fin. A main pipe penetrates through multiple fins, and a first auxiliary pipe is arranged between the first fin and the third fin; a second auxiliary pipe is matched between the second fin and the fourth fin; a connecting pipe is arranged between the main pipes between the first fin and the fourth fin and between the main pipes of the second fin and the third fin. Through the cooperation between the first auxiliary pipe, the second auxiliary pipe, the connecting pipe, and the main pipe, the liquid entering from the liquid inlet pipe can be effectively and quickly filled into the main pipes matched with the fins through the cooperation between the main pipe, the connecting pipe, the first auxiliary pipe, and the second auxiliary pipe. Summary of the Invention

[0007] The purpose of the present invention is to provide a plate-fin heat exchanger for improving uneven liquid distribution. In this device, a connecting pipe is arranged between the main pipes between the first fin and the fourth fin and between the main pipes of the second fin and the third fin. First auxiliary pipes and second auxiliary pipes are respectively matched on the main pipes between the first fin and the third fin and between the second fin and the fourth fin. In this way, when adding liquid, the main pipes matched with the fins can be effectively and quickly filled, and the overall heat exchange efficiency of multiple fins can be realized; to solve the problems in the above background technology.

[0008] To achieve the above purpose, the present invention provides the following technical solutions:

[0009] A plate-fin heat exchanger for improving uneven liquid distribution, including a fin assembly; the fin assembly includes a first fin, a second fin, a third fin, and a fourth fin; a main pipe penetrates between the first fin, the second fin, the third fin, and the fourth fin; liquid outlet pipes and liquid inlet pipes are respectively and cooperatively installed at the ends of the main pipes of the third fin and the fourth fin.

[0010] A first auxiliary pipe is arranged between the first fin and the third fin; a second auxiliary pipe is arranged between the second fin and the fourth fin, and the first auxiliary pipe and the second auxiliary pipe are arranged in a cross-penetrating manner.

[0011] As a further technical solution of the present invention, a connecting pipe is cooperatively arranged between the main pipes at the bottoms of the first fin and the fourth fin and the main pipes at the bottoms of the second fin and the third fin.

[0012] As a further technical solution of the present invention, a heat exchanger is cooperatively installed at the bottom of the fin assembly; the heat exchanger includes a mounting plate; the mounting plate is cooperatively installed with the main pipes at the bottoms of the first fin and the fourth fin and the main pipes at the bottoms of the second fin and the third fin through buckles.

[0013] As a further technical solution of the present utility model, a fan is installed on the side of the mounting plate away from the buckle in a mating manner.

[0014] As a further technical solution of the present utility model, the first fin, the second fin, the third fin and the fourth fin are arranged in a cross shape; at least two groups of heat dissipation fins are arranged on one of the fins.

[0015] As a further technical solution of the present utility model, both the first auxiliary pipe and the second auxiliary pipe penetrate through the first fin, the second fin, the third fin and the fourth fin and are connected to the main pipe at the mating part with the main pipe.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In the present utility model, during use, a liquid inlet pipe is arranged at one end of the main pipe. When the liquid enters the main pipe, the liquid levels inside the main pipe are made flush through the communicating pipe. When adding liquid continuously, when the liquid reaches a certain liquid level, the first auxiliary pipe between the first fin and the third fin and the second auxiliary pipe between the second fin and the fourth fin are used to connect the main pipes. In this way, when the liquid flows, it effectively avoids the liquid from passing through the spaces between the fourth fin, the first fin, the second fin and the third fin, greatly improving the working efficiency of multiple fins.

[0018] In the present utility model, multiple fins are arranged in a rectangular shape, so that the heat dissipation inside the four fins is slower. Thus, the heat accumulated inside is effectively dissipated by the heat exchanger at the bottom. The mounting plate is fixedly installed on the main pipe through the buckle. In this way, when dissipating heat through the fan, it effectively ensures that the position of the fan will not shift, greatly improving the heat exchange efficiency of the fins.

Detailed implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , in the embodiment of the present invention, a plate-fin heat exchanger for improving uneven liquid distribution includes a fin assembly 1; the fin assembly 1 includes a first fin 11, a second fin 12, a third fin 13 and a fourth fin 14; a main pipe 10 runs through between the first fin 11, the second fin 12, the third fin 13 and the fourth fin 14; an outlet pipe 18 and an inlet pipe 17 are cooperatively installed at the ends of the main pipe 10 of the third fin 13 and the fourth fin 14.

[0027] A first auxiliary pipe 15 is arranged between the first fin 11 and the third fin 13; a second auxiliary pipe 16 is arranged between the second fin 12 and the fourth fin 14, and the first auxiliary pipe 15 and the second auxiliary pipe 16 are arranged in a cross-through manner.

[0028] Specifically, a connecting pipe 19 is cooperated between the main pipes 10 at the bottoms of the first fin 11 and the fourth fin 14 and the main pipes 10 at the bottoms of the second fin 12 and the third fin 13;

[0029] The bottom of the fin assembly 1 is cooperatively installed with a heat exchanger 2; the heat exchanger 2 includes a mounting plate 20; the mounting plate 20 is cooperatively installed with the main pipes 10 at the bottoms of the first fin 11 and the fourth fin 14 and the main pipes 10 at the bottoms of the second fin 12 and the third fin 13 through buckles 22.

[0030] By adopting the above technical solution, during use, a liquid inlet pipe 17 is provided at one end of the main pipe 10. When liquid enters the main pipe 10, the liquid levels inside the main pipe 10 are made flush through the connecting pipe 19. When more liquid is added and reaches a certain liquid level, the main pipes 10 are connected through the first auxiliary pipe 15 between the first fin 11 and the third fin 13 and the second auxiliary pipe 16 between the second fin 12 and the fourth fin 14. In this way, when the liquid flows, it effectively prevents the liquid from passing through the space between the fourth fin 14, the first fin 11, the second fin 12, and the third fin 13, greatly improving the working efficiency of multiple fins.

[0031] On the side of the mounting plate 20 away from the buckle 22, a fan 21 is cooperatively mounted.

[0032] In this embodiment, the first fin 11, the second fin 12, the third fin 13, and the fourth fin 14 are arranged in a cross shape; at least two groups of heat dissipation fins are provided on one of the fins.

[0033] Both the first auxiliary pipe 15 and the second auxiliary pipe 16 penetrate through the first fin 11, the second fin 12, the third fin 13, and the fourth fin 14 at the mating part with the main pipe 10 and are connected to the main pipe 10.

[0034] By adopting the above technical solution, multiple fins are arranged in a rectangle. In this way, the heat dissipation inside the four fins is relatively slow. Thus, the heat accumulated inside is effectively dissipated by the heat exchanger 2 at the bottom. The mounting plate 20 is fixedly installed on the main pipe 10 through the buckle 22. In this way, when the fan 21 dissipates heat, it effectively ensures that the position of the fan 21 will not shift, greatly improving the heat exchange efficiency of the fins.

[0035] The working principle of the present utility model is: during use, a liquid inlet pipe 17 is provided at one end of the main pipe 10. When liquid enters the main pipe 10, the liquid levels inside the main pipe 10 are made flush through the connecting pipe 19. When more liquid is added and reaches a certain liquid level, the main pipes 10 are connected through the first auxiliary pipe 15 between the first fin 11 and the third fin 13 and the second auxiliary pipe 16 between the second fin 12 and the fourth fin 14. In this way, when the liquid flows, it effectively prevents the liquid from passing through the space between the fourth fin 14, the first fin 11, the second fin 12, and the third fin 13, greatly improving the working efficiency of multiple fins.

[0036] Multiple fins are arranged in a rectangular shape. In this way, the heat dissipation inside the four fins is relatively slow. Thus, the heat exchanger 2 at the bottom effectively dissipates the heat accumulated inside. The mounting plate 20 is fixedly installed on the main pipe 10 through the buckle 22. In this way, when dissipating heat through the fan 21, it effectively ensures that the position of the fan 21 will not shift, greatly improving the heat exchange efficiency of the fins.
