Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to a finned heat exchanger with reduced resistance. Background Technology

[0002] The main structure of a heat exchanger consists of heat exchange tubes and heat exchanger fins. Refrigerant flows inside the heat exchange tubes, releasing or absorbing heat and transferring it to the heat exchanger fins. The heat exchanger fins increase the contact area between the heat source and the air, enhancing the heat transfer process. In existing heat exchangers, louvered heat exchanger fins are commonly used to improve heat exchange efficiency.

[0003] According to a heat exchanger fin and heat exchanger disclosed in the public notice (publication number: CN219141612U), the above application significantly reduces the wind resistance coefficient of the louver blades by setting a louver blade structure, thereby reducing air resistance. At the same time, the surface area of ​​the louver blades is increased, thereby increasing the total heat exchange surface area. By setting turbulence deflectors, the flow field on the leeward side of the heat exchange tube is improved, and the heat exchange on the leeward side of the heat exchange tube is enhanced, thus improving the overall heat exchange capacity of the heat exchanger.

[0004] However, in actual use, the heat dissipation fins of the above-mentioned devices are almost identical in shape, which causes the heat dissipation fins in the center of the radiator to be blocked and obstructed, thus limiting the heat exchange efficiency between them and the external airflow, thereby reducing the overall heat dissipation efficiency of the heat exchanger to a certain extent. In view of this, we propose a finned heat exchanger with reduced resistance. Utility Model Content

[0005] The purpose of this invention is to provide a finned heat exchanger with reduced resistance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a finned heat exchanger with reduced resistance, comprising a first heat dissipation fin, a heat exchange pipe being installed through and fixedly mounted on the inner wall of the first heat dissipation fin, a second heat dissipation fin parallel to the first heat dissipation fin being provided on the outer wall of the heat exchange pipe, an edge straight piece being provided at the end of the first heat dissipation fin, a U-shaped groove being provided on the inner wall of the edge straight piece away from the center of the first heat dissipation fin, the first heat dissipation fin including an inclined edge, the inclined edge being provided on the side of the edge straight piece, an arc-shaped protrusion being fixedly mounted on the side wall of the inclined edge, the number of the arc-shaped protrusions being provided in multiple sets, and the multiple sets of arc-shaped protrusions being evenly distributed in a linear array on the side wall of the inclined edge, an arc-shaped groove being provided between two adjacent sets of arc-shaped protrusions.

[0007] Preferably, the number of heat dissipation fins one and two is set in several groups, and each of the several groups of heat dissipation fins one and two is divided into two parts that are mirror images of each other, and the inclined edges of the two parts of heat dissipation fins one and two are arranged close to each other.

[0008] Preferably, the arc-shaped protrusions between adjacent heat dissipation fins 1 and 2 are arranged in an alternating manner, so that when air from the external environment flows through the radiator, the arc-shaped grooves and protrusions make it easier for the air to flow to the gap between heat dissipation fins 1 and 2 near the center of the radiator, so as to carry away more heat.

[0009] Preferably, the number of edge strips is set to two sets, and the two sets of edge strips are mirror images of the left and right ends of the first heat dissipation fin, and the two ends of the second heat dissipation fin are provided with another set of edge strips.

[0010] Preferably, the heat exchange pipe is hollow inside, and the inner walls of the first and second heat dissipation fins are provided with through holes that are adapted to the outer diameter of the heat exchange pipe, so as to facilitate the installation of the heat exchange pipe.

[0011] Preferably, a deflection groove is formed on the arc-shaped surface of the arc-shaped protrusion.

[0012] Preferably, the deflection groove is arranged at an angle, intersecting the inclined edge.

[0013] Compared with the prior art, this utility model provides a finned heat exchanger with reduced resistance, which has the following beneficial effects:

[0014] 1. This reduced-resistance finned heat exchanger, through the staggered arrangement of arc-shaped protrusions and arc-shaped grooves on adjacent heat dissipation fins one and two on the heat exchange pipe, allows air from the external environment to flow more easily to the gap between heat dissipation fins one and two near the center of the heat dissipation fins when it passes through the radiator, thus carrying away more heat. The inclined edges further increase the contact area between heat dissipation fins one and two and the air, further improving the heat exchange performance of the device.

[0015] 2. This reduced-resistance finned heat exchanger has inclined deflection grooves on the arc-shaped protrusions that intersect with the inclined edges. These grooves partially guide the air passing through the inclined edges of the surfaces of fin one and fin two, allowing it to enter the gap between fin one and fin two, thereby carrying away more heat and improving the heat dissipation performance of the heat exchanger.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a finned heat exchanger with reduced resistance, including a heat dissipation fin 100, a heat exchange pipe 200 that is installed through and fixedly mounted on the inner wall of the heat dissipation fin 100, a heat dissipation fin 300 parallel to the heat dissipation fin 100 on the outer wall of the heat exchange pipe 200, and an edge straight piece 101 at the end of the heat dissipation fin 100. A U-shaped groove 1 is formed on the inner wall of the edge straight piece 101 away from the center of the heat dissipation fin 100. 02. The heat dissipation fin 100 includes an inclined edge 103, which is disposed on the side of the edge straight plate 101. An arc-shaped protrusion 104 is fixedly installed on the side wall of the inclined edge 103. The number of arc-shaped protrusions 104 is arranged in multiple sets, and the multiple sets of arc-shaped protrusions 104 are evenly distributed in a linear array on the side wall of the inclined edge 103. An arc-shaped groove 105 is provided between two adjacent sets of arc-shaped protrusions 104. A deflection groove 106 is opened on the arc surface of the arc-shaped protrusion 104.

[0021] In one embodiment of this utility model, several sets of heat dissipation fins 100 and 300 are provided, and each set of heat dissipation fins 100 and 300 is divided into two mirror-image parts. The inclined edges 103 of the two parts of heat dissipation fins 100 and 300 are arranged close to each other. Meanwhile, the interior of the heat exchange pipe 200 is hollow, and the inner walls of the heat dissipation fins 100 and 300 are provided with through holes that are adapted to the outer diameter of the heat exchange pipe 200, so as to facilitate the installation of the heat exchange pipe 200 and ensure the contact efficiency between the heat exchange pipe 200 and the heat dissipation fins 100 and 300, thereby achieving effective heat exchange.

[0022] Furthermore, during the installation of the radiator, the arc-shaped protrusions 104 between adjacent heat dissipation fins 100 and 300 are staggered, that is, the arc-shaped protrusions 104 of heat dissipation fin 100 correspond to the positions of the arc-shaped grooves 105 of heat dissipation fin 300. This allows air from the external environment to flow more easily to the gap between heat dissipation fins 100 and 300 near the center of the radiator through the arc-shaped grooves 105 and arc-shaped protrusions 104, thus carrying away more heat. At the same time, because the gap between heat dissipation fins 100 and 300 is small, when the external air velocity is greater, according to Bernoulli's principle, the hot air in the gap between heat dissipation fins 100 and 300 is more likely to flow outward and carry away heat. In addition, the inclined edge 103 can increase the contact area between heat dissipation fins 100 and 300 and the air, further improving the heat exchange performance of the device.

[0023] In this embodiment of the utility model, two sets of edge strips 101 are provided, and the two sets of edge strips 101 are mirror images of the left and right ends of the heat dissipation fin one 100. Another set of edge strips 101 is provided at both ends of the heat dissipation fin two 300. At the same time, by setting the edge strips 101, in conjunction with the U-shaped groove 102, the heat dissipation performance of the heat dissipation fin one 100 and the heat dissipation fin two 300 is ensured, while facilitating the installation of the heat dissipation fin one 100 and the heat dissipation fin two 300 and the removal of the heat sink.

[0024] It is worth noting that the deflection groove 106 is set in an inclined shape that intersects with the inclined edge 103, thereby partially guiding the air passing through the inclined edge 103 on the surface of the heat dissipation fin 100 and the heat dissipation fin 2 300, so that it can enter the gap between the heat dissipation fin 100 and the heat dissipation fin 2 300, thereby taking away more heat and improving the heat dissipation performance of the heat exchanger.

[0025] In this invention, during use, the heat exchange pipe 200 is connected to the water pipe of the circulating cooling system, and the circulating cooling system is started so that the cooling water can flow inside the heat exchange pipe 200. Heat exchange is achieved through the heat exchange pipe 200 and the heat dissipation fins 100 and 300. At the same time, the staggered arrangement of the heat dissipation fins 100 and 300 at adjacent locations on the heat exchange pipe 200 allows air from the external environment to flow more easily to the gap between the heat dissipation fins 100 and 300 near the center of the radiator through the arc-shaped groove 105 and arc-shaped protrusion 104, thus carrying away more heat. The inclined edge 103 increases the contact area between the heat dissipation fins 100 and 300 and the air, further improving the heat exchange performance of the device.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
