Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat exchanger fins, in particular to a heat exchanger fin with a protective structure. Background Art
[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers. Generally, a heat exchanger includes a header, a flat tube and fins, but the fins are thin and have sharp edges, which can easily scratch the skin. The existing heat exchanger fins have a simple structure, and the edges are directly exposed. There are also protective plates installed at both ends of the fins to protect the two ends, but the long sides of the heat exchanger fins are still exposed, and there is still a risk of scratching the skin. Therefore, those skilled in the art provide a heat exchanger fin with a protective structure to solve the problems raised in the above background technology. Utility Model Content
[0003] The purpose of the utility model is to provide a heat exchanger fin with a protective structure to solve the problems raised in the above background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A heat exchanger fin with a protective structure comprises a fin body, a mounting hole is opened inside the fin body, both side ends of the fin body are bent to form short side protection strips, and the upper and lower side ends of the fin body are bent to form long side protection strips, the two short side protection strips on both sides are directed toward the front side and the rear side of the fin body respectively, and the two long side protection strips on both sides are also directed toward the front side and the rear side of the fin body respectively.
[0006] As a further solution of the utility model: the long side protection strip is a long folded edge strip, and the long folded edge strip and the fin body are perpendicular to each other.
[0007] As a further solution of the utility model: the long side protection strip is a long curved side strip, and the side of the long curved side strip away from the fin body abuts against the surface of the fin body.
[0008] As a further solution of the utility model: the short side protection strip and the fin body are perpendicular to each other.
[0009] As a further solution of the utility model: the width of the short side protection strip is greater than the width from the long side protection strip to the fin body.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] By providing short side protection strips and long side protection strips, the left and right sides and the upper and lower sides of the fin body can be prevented from being exposed, thereby preventing the sharp edges of the fins from cutting the skin. The two short side protection strips and the two long side protection strips are respectively provided on the front and back sides of the fin body. When installing the fins, the fins can be positioned by the short side protection strips to prevent the fins from being too close to each other. The width of the long side protection strip is smaller than that of the short side protection strip, and the upper and lower edges of the fin body will not fit together. A certain gap is retained to facilitate heat exchange between the gap and the outside. The length of the long side protection strip is longer than that of the short side protection strip, and the heat exchange efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] See also Figures 1-2 In an embodiment of the utility model, a heat exchanger fin with a protective structure includes a fin body 1, a mounting hole 2 is opened inside the fin body 1, both side ends of the fin body 1 are bent to form short side protection strips 3, and the upper and lower side ends of the fin body 1 are bent to form long side protection strips 4, the two short side protection strips 3 on both sides are respectively directed toward the front and rear sides of the fin body 1, and the two long side protection strips 4 on both sides are also respectively directed toward the front and rear sides of the fin body 1, and the short side protection strips 3 and the fin body 1 are perpendicular to each other.
[0016] In the first embodiment, the long side protection strip 4 is a long folded edge strip 41 , and the long folded edge strip 41 and the fin body 1 are perpendicular to each other.
[0017] In the second embodiment, the long side protection strip 4 is configured as a long curved side strip 42 , and a side of the long curved side strip 42 away from the fin body 1 abuts against the surface of the fin body 1 .
[0018] Preferably, the width of the short side protection strip 3 is greater than the width from the long side protection strip 4 to the fin body 1 .
[0019] The working principle of the utility model is as follows: by setting the short side protection strip 3 and the long side protection strip 4, the left and right sides of the fin body 1 are bent by the short side protection strip 3 to prevent the left and right sides of the fin body 1 from being exposed to the outside, and the upper and lower sides of the fin body 1 can be bent by the long side protection strip 4 to prevent the upper and lower sides of the fin body 1 from being exposed to the outside, and the short side protection strips 3 on both sides of the fin body 1 and the long side protection strips 4 on both sides are respectively arranged on the front and rear sides of the fin body 1. When the fin is installed on the heat exchanger, it can be installed by the previous fin body The short side protection strip 3 on the rear side of the body 1 abuts against the front surface of the next fin body 1, and the fin bodies 1 are directly separated into fixed positions by the short side protection strip 3, and the width of the long side protection strip 4 is smaller than the short side protection strip 3. When the two fin bodies 1 are installed, their upper and lower edges will not be completely close to and fit together, and there will be a certain gap, which is convenient for heat exchange with the outside through the gap, and the length of the long side protection strip 4 is longer than that of the short side protection strip 3, leaving a gap at the long side of the fin body 1, which has a higher heat exchange efficiency than leaving gaps at the short sides on the left and right sides.
[0020] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
