Description

Technical Field

[0001] This utility model relates to the field of surface cooler technology, and in particular to a surface cooler with a high-efficiency heat exchange structure. Background Technology

[0002] Current surface coolers typically exchange heat through heat dissipation fins. However, these fins are mainly thin sheets, which are not only easy to bend, but also difficult to trap air during airflow, resulting in short contact time with the air and poor heat dissipation. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a surface cooler with a highly efficient heat exchange structure.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] Surface coolers with high-efficiency heat exchange structures, including

[0006] Water inlet pipe;

[0007] Water outlet pipe;

[0008] The heat dissipation pipe has its first end connected to the water inlet pipe and its last end connected to the water outlet pipe;

[0009] The heat dissipation fins include a body and a first row of holes, a second row of holes, and a third row of holes arranged at intervals along the width direction of the body for the heat dissipation pipe to pass through back and forth, wherein the second row of holes is offset relative to the first row of holes and the third row of holes.

[0010] The body is stamped into a high-level part and a low-level part that bulge in the middle. The first hole row and the third hole row are located on the low-level part, and the second hole row is located on the high-level part.

[0011] As described above, in the surface cooler with a high-efficiency heat exchange structure, the second perforated plate is punched out to form a third through-hole tube, and the tube wall of the third through-hole tube is compressed to form a collapse zone.

[0012] As described above, the surface cooler with a highly efficient heat exchange structure has a W-shaped collapse zone, and the third through-hole tube is folded back and forth.

[0013] As described above, the surface cooler with a high-efficiency heat exchange structure has a connecting part between the high-order part and the low-order part. The connecting part is provided with a slot, and the upper and lower parts of the slot are bent towards the inner and outer sides of the connecting part to form air guide holes.

[0014] As described above, in the surface cooler with a high-efficiency heat exchange structure, the upper part of the slot is bent outwards towards the connecting part, and the lower part is bent inwards towards the connecting part.

[0015] As described above, the surface cooler with a high-efficiency heat exchange structure has the slot corresponding to the third through-hole tube.

[0016] In the surface cooler with a high-efficiency heat exchange structure as described above, the height difference between the higher-order section and the lower-order section is equal to the length of the third through-hole tube.

[0017] As described above, the surface cooler with a highly efficient heat exchange structure has the third through-hole tube opening widened outwards in a funnel shape.

[0018] The beneficial effects of this application are:

[0019] This invention provides a surface cooler with a high-efficiency heat exchange structure. By stamping out a high-level section, the contact area with air is increased without changing the width. At the same time, when air flows through the heat dissipation fins, a windproof surface is formed, which creates resistance to air flow, thereby increasing the air residence time and improving the heat dissipation effect.

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Surface coolers with high-efficiency heat exchange structures, including

[0026] Water inlet pipe 1;

[0027] Water outlet pipe 2;

[0028] The heat dissipation pipe 3 has its first end connected to the water inlet pipe 1 and its last end connected to the water outlet pipe 2;

[0029] The heat dissipation fins 4 include a body 41, and a first row of holes 42, a second row of holes 43 and a third row of holes 44 arranged at intervals along the width direction of the body 41 for the heat dissipation pipe 3 to pass through back and forth, wherein the second row of holes 43 is offset relative to the first row of holes 42 and the third row of holes 44.

[0030] The body 41 is stamped into a high-level portion 45 and a low-level portion 46 that protrude in the middle. The first hole row 42 and the third hole row 44 are located on the low-level portion 46, and the second hole row 43 is located on the high-level portion 45.

[0031] This invention provides a surface cooler with a high-efficiency heat exchange structure. By stamping out a high-level section, the contact area with air is increased without changing the width. At the same time, when air flows through the heat dissipation fins, a windproof surface is formed, which creates resistance to air flow, thereby increasing the air residence time and improving the heat dissipation effect.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the second hole row 43 is punched to form a third through hole tube 47, and the tube wall of the third through hole tube 47 is compressed to form a collapse zone 471.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the collapse zone 471 is W-shaped, with the third through-hole tube 47 folded back and forth as previously described. This increases structural strength and the area in contact with air.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, a connecting portion 48 is provided between the higher-order portion 45 and the lower-order portion 46. The connecting portion 48 is provided with a slot 49, and the upper and lower parts of the slot 49 are bent toward the inner and outer sides of the connecting portion 48 respectively to form air guide holes 40.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the upper part of the slot 49 is bent outwards towards the connecting portion 48, and the lower part is bent inwards towards the connecting portion 48. When manufacturing the heat dissipation fins, the slot is first cut, then the higher-level portion is stamped, and finally the third through-hole tube is stamped.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the slot 49 is provided corresponding to the third through-hole pipe 47, so that the airflow is directed towards the third through-hole pipe.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the height difference between the higher-order portion 45 and the lower-order portion 46 is equal to the length of the third through-hole tube 47. This avoids the situation where the heat dissipation fins cannot abut against each other when they overlap, thus preventing them from being suspended and causing bending.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, the opening of the third through-hole tube 47 is widened outwards into a trumpet shape. This facilitates contact between multiple heat dissipation fins when stacked, thereby preventing overlap.

[0039] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
