Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange fin expansion, in particular to a heat exchange fin expansion device. Background Art

[0002] In traditional heat exchange system designs, heat exchange fins are typically placed closely together to maximize heat exchange area and improve heat transfer efficiency. However, while this close arrangement provides efficient heat exchange, it also presents challenges with heat dissipation. Due to the lack of sufficient space between the fins, heat cannot be effectively dissipated from the fin surface to the surrounding environment, limiting the overall heat dissipation performance of the system.

[0003] To address this issue, traditional methods often require manual intervention, using specialized tools or devices to flare the adjacent heat exchanger fins. The purpose of flaring is to create a gap between the fins, allowing air or cooling media to flow more efficiently, thereby improving heat dissipation efficiency.

[0004] However, debris, metal powder, and other debris generated during the expansion process can easily fall into the gaps between the heat exchanger fins. These debris not only reduce heat transfer efficiency but can also block the flow channels of the cooling medium, leading to localized overheating or concentrated thermal stress, thus shortening the service life of the heat exchanger fins. Utility Model Content

[0005] In response to the above-mentioned defects, the present invention proposes a heat exchanger fin expansion device. The bottom of the expansion component is a sealed structure. Therefore, during the expansion process, it can effectively prevent debris and other debris from splashing into the two adjacent heat exchanger fins that have just been expanded, maintain the cleanliness of the inside of the heat exchanger, avoid the degradation or failure of heat dissipation performance due to debris contamination, and solve the problem that during the expansion process of traditional heat exchanger fins, debris and other debris are easily dropped into the gap between the two adjacent heat exchanger fins that have just been expanded.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] A heat exchanger fin flaring device includes a handle, a flaring assembly and a connecting rod assembly. The two ends of the connecting rod assembly are respectively connected to two handles.

[0008] The flaring assembly includes a flaring plate and a flaring shaft. The tops of the two flaring plates are fixedly connected to the corresponding handles respectively, and the bottoms of the two flaring plates are rotatably connected to the flaring shaft. The length direction of the flaring shaft is consistent with the rotation of the flaring plates.

[0009] The expansion plate includes a mounting portion, a stress dispersion portion and a horizontal portion. The mounting portion is fixedly connected to the handle, the two ends of the mounting portion are respectively connected to the top of the corresponding stress dispersion portion, and the bottom of the stress dispersion portion is connected to the horizontal portion.

[0010] A buffer spring is provided between the two mounting parts, and two ends of the buffer spring are respectively connected to the two mounting parts.

[0011] The connecting rod assembly includes a connecting rod and a pedal. The head end of the connecting rod is hinged to the corresponding handle, and the tail end of the connecting rod is hinged to the pedal. The tail ends of the two connecting rods are located on the same axis.

[0012] The handle includes a handle portion, a connecting portion, a vertical portion, an inclined portion, and a welding portion. The two ends of the handle portion are respectively vertically connected to the tops of the two vertical portions. The bottom of the vertical portion is fixedly connected to the tops of the inclined portions. The inclined portions are inclined inward from top to bottom.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means more than two.

[0024] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installation," "splicing," and "connection" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] The following combination Figures 1 to 2 , describing a heat exchanger fin expansion device according to an embodiment of the present utility model.

[0026] A heat exchange fin flaring device comprises a handle 1, a flaring assembly 2 and a connecting rod assembly 3, wherein the two ends of the connecting rod assembly 3 are respectively connected to the two handles 1, and the flaring assembly 2 is provided at the bottom of the handle 1. Figure 2 Left view / right view of the heat exchanger fin expanding device, the expanding component 2 is a V-shaped structure, the bottom of the expanding component 2 is a sealing structure, and the handle 1 is used to change the opening size of the V-shaped structure.

[0027] The user grips the handle 1, which is in its initial state. At this time, the opening of the flaring component 2 at the bottom of the handle 1 is the smallest, making it convenient for the user to place the flaring device of this solution on the heat exchange plate and ensure that the bottom of the flaring component 2 can extend into two adjacent heat exchange plates.

[0028] The user then separates the two handles 1 outward, and the handles 1 drive the top of the flaring assembly 2 to move, so that the V-shaped opening of the flaring assembly 2 becomes larger, thereby easily changing the opening size of the flaring assembly 2 at the bottom of the handle 1.

[0029] At this time, the V-shaped expansion component 2 can distribute the expansion force more evenly, ensuring that the heat exchange plate is uniformly deformed during the expansion process, thereby avoiding deformation or damage of the heat exchange plate during the expansion process, and improving the expansion accuracy and consistency of this solution.

[0030] Moreover, the bottom of the expansion component 2 is a sealed structure. Therefore, during the expansion process, it can effectively prevent debris and other debris from splashing into the two adjacent heat exchange plates that have just been expanded, maintain the cleanliness of the inside of the heat exchanger, avoid the degradation or failure of heat dissipation performance due to debris contamination, and solve the problem that during the expansion process of traditional heat exchange plates, debris and other debris are easily dropped into the gap between the two adjacent heat exchange plates that have just been expanded.

[0031] The flaring assembly 2 includes a flaring plate 21 and a flaring shaft 22. The tops of the two flaring plates 21 are fixedly connected to the corresponding handles 1 respectively, and the bottoms of the two flaring plates 21 are rotatably connected to the flaring shaft 22. The length direction of the flaring shaft 22 is consistent with the rotation of the flaring plate 21.

[0032] Because the top of the flaring plate 21 is fixedly connected to the handle 1 and the bottom of the flaring plate 21 is rotatably connected to the flaring shaft 22, swinging the two handles 1 outward causes the tops of the two flaring plates 21 to separate outward, forming a gradually widening opening, thus completing the flaring operation without the need for complex adjustments and settings. Furthermore, the bottoms of the flaring plates 21 always fit together, a design that not only ensures the flaring plates 21 maintain a stable rotational trajectory during the flaring process but also prevents debris and other debris from falling into the heat exchange fins through the gap between the two flaring plates 21.

[0033] Furthermore, the length of the flaring shaft 22 is aligned with the rotation of the flaring plate 21, which helps reduce deviation and shaking during the flaring process, thereby improving the precision and stability of the flaring. Furthermore, the provision of the flaring shaft 22 can also prevent the flaring plate 21 from twisting and deforming after long-term use.

[0034] The expansion plate 21 includes a mounting portion 23, a stress dispersion portion 24 and a horizontal portion 25. The mounting portion 23 is fixedly connected to the handle 1, and the two ends of the mounting portion 23 are respectively connected to the top of the corresponding stress dispersion portion 24, and the bottom of the stress dispersion portion 24 is connected to the horizontal portion 25.

[0035] By slowly rotating handle 1 outward, the fixed mounting portion 23 effectively transfers the flaring force to the rest of the flaring plate 21, preventing force loss or shaking due to a loose connection. The stress dissipation portion 24 smoothly connects the mounting portion 23 and the horizontal portion 25, dispersing the stress generated during the flaring process and ensuring that the force is evenly transferred to the heat exchanger fins, reducing stress concentration and preventing deformation or damage to the fins during the flaring process.

[0036] A buffer spring 26 is provided between the two mounting portions 23 , and both ends of the buffer spring 26 are connected to the two mounting portions 23 , respectively.

[0037] During the expansion process, due to the operation of the staff, a large impact force may be generated. The buffer spring 26 can effectively absorb and slow down the impact force, thereby reducing the damage to the expansion plate 21 and the heat exchange plate caused by excessive force.

[0038] Moreover, when the flaring operation is completed, the buffer spring 26 contracts inward and recovers its deformation, thereby restoring the flaring plate 21, the handle 1 and the connecting rod assembly 3 to their initial states, so that the staff can quickly perform flaring operations on other heat exchange plates.

[0039] The connecting rod assembly 3 includes a connecting rod 31 and a pedal 32. The head end of the connecting rod 31 is hinged to the corresponding handle 1, and the tail end of the connecting rod 31 is hinged to the pedal 32. The tail ends of the two connecting rods 31 are located on the same axis.

[0040] The operator presses down on the pedal 32, causing the connecting rods 31 at both ends to rotate outward, thereby driving the handle 1 and the flaring plate 21 to flare the heat exchanger fins. This operation method is more labor-saving than directly operating the handle 1 manually, reducing the operator's hand movement during the flaring process and reducing the safety risks caused by hand fatigue or misoperation.

[0041] The ends of the two connecting rods 31 are located on the same axis, which ensures that the pedal 32 can smoothly drive the two connecting rods 31 to move synchronously during the pedaling process, avoiding the flaring error caused by the uncoordinated movement of the connecting rods 31.

[0042] Furthermore, by limiting the length of the two connecting rods 31, the maximum distance that the flaring plate 21 can expand outward can be precisely controlled. This design allows the operator to flexibly adjust the flaring degree according to the specifications of the heat exchanger and the flaring requirements.

[0043] The handle 1 includes a handle portion 11, a connecting portion 12, a vertical portion 13, an inclined portion 14, and a welding portion 15. The two ends of the handle portion 11 are respectively vertically connected to the tops of the two vertical portions 13. The bottom of the vertical portion 13 is fixedly connected to the tops of the inclined portions 14. The inclined portions 14 are inclined inward from top to bottom. The bottom of the inclined portion 14 is fixedly connected to the tops of the welding portions 15. The welding portions 15 are fixedly connected to the corresponding flared plates 21.

[0044] Two ends of the connecting portion 12 are perpendicularly connected to the two vertical portions 13 , and the connecting portion 12 is hinged to the corresponding connecting rod 31 .

[0045] The design of the handle 11 allows the operator to comfortably hold and control the flaring device. The combination of the vertical portion 13 and the inclined portion 14 makes the handle 1 present an ergonomic shape as a whole, helping the operator maintain a correct posture during long hours of work and reducing muscle and joint stress.

[0046] The connecting portion 12 serves as a bridge between the vertical portion 13 and the connecting rod 31 and is connected in a hinged manner, thereby ensuring a stable connection and flexible rotation between the handle 1 and the connecting rod 31 .

[0047] The welding portion 15 connects the handle 1 and the flaring plate 21 , and through a fixed connection, the stability and accuracy of the flaring plate 21 during the flaring process can be ensured.

[0048] The outer wall of the expansion plate 21 is fixedly connected to the inner wall of the welding portion 15 .

[0049] When the outer wall of the flared plate 21 is fixedly connected to the inner wall of the welding portion 15, the welding portion 15 can limit the depth of the flared plate 21 extending into the heat exchange fin, ensuring that the depth of the flared plate 21 extending into the heat exchange fin remains consistent each time the heat exchange fin is flared, thereby ensuring that the heat exchange fins have uniform spacing and good fluid channels after assembly, thereby improving the heat exchange efficiency and overall performance of the heat exchanger.

[0050] Furthermore, the distance between the weld portion 15 and the bottom of the flared plate 21 limits the insertion depth of the flared plate 21, thereby effectively preventing excessive flaring of the flared plate 21. If the flared plate 21 is excessively inserted, it may cause excessive stretching or damage to the material of the heat exchanger fins, affecting the strength and service life of the heat exchanger fins.

[0051] Therefore, when using the flaring device, workers do not need to pay extra attention to or frequently adjust the insertion depth of the flaring plate 21. This fixed connection automatically ensures depth accuracy, making operation simpler and more convenient. This design reduces operational difficulty, especially for inexperienced operators, and reduces flaring errors caused by human factors.

[0052] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without undue creative effort, and such implementations will fall within the scope of protection of the present invention.
