Description

Technical Field

[0001] This utility model relates to the field of refrigerator evaporator fin technology, specifically a refrigerator evaporator fin with turbulence holes on its surface. Background Technology

[0002] The evaporator fins of a refrigerator are a key component in the refrigerator's refrigeration system, mainly used to enhance heat exchange efficiency.

[0003] Conventional refrigerator evaporator fins are flat, and the dense arrangement of fins increases the contact area between the evaporator and the air, thereby improving heat exchange efficiency. However, relying solely on the contact area between the fins and the air for heat dissipation has limited efficiency. This application proposes a refrigerator evaporator fin with surface perforations. The fin type is a surface perforated structure. When the circulating air passes through the perforations on the fin surface, part of the circulating air passes through the holes, forming a high and low pressure area near the holes. The circulating air generates a swirling effect, creating negative pressure and turbulence, which makes the heat exchange between the circulating air and the evaporator more complete, achieving more energy-efficient and faster cooling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a refrigerator evaporator fin with surface turbulence holes. This solves the problem that conventional refrigerator evaporator fins are all flat fin structures. While the dense arrangement of fins increases the contact area between the evaporator and the air to improve heat exchange efficiency, the heat dissipation efficiency is limited by relying solely on the contact area between the fins and the air.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a refrigerator evaporator fin with surface turbulence holes, comprising several fin bodies, each of the fin bodies on both sides being equipped with an mounting plate, an evaporator tube being inserted between the two mounting plates and the several fin bodies, the fin bodies being provided with insertion holes and turbulence holes, the evaporator tube being inserted into the insertion holes, the turbulence holes being distributed in a staggered arrangement on the outer peripheral wall of the insertion holes, and the spacing between the inlet holes of the turbulence holes being smaller than the spacing between the outlet holes.

[0006] Preferably, the fin body has connection holes at its four corners, and a connector rod is inserted into the connection holes.

[0007] Preferably, the plug rod is inserted into the mounting plate, and a fixing seat is fixedly connected to the outer peripheral wall of the mounting plate corresponding to the plug rod. The fixing seat is slidably connected to the plug rod, and the fixing seat and the plug rod are fixed by bolts.

[0008] Preferably, mounting bases are fixedly connected to both sides of the mounting plate.

[0009] Preferably, a spring-loaded telescopic rod is provided between adjacent fin bodies.

[0010] Preferably, mounting holes are provided on both sides of the fin body, and the spring-type telescopic rod is installed in the mounting holes.

[0011] Preferably, a sealing gasket is installed in the insertion hole on the fin body, and the sealing gasket is in contact with the evaporator tube.

[0012] This utility model discloses a refrigerator evaporator fin with surface perforations, which has the following beneficial effects:

[0013] The refrigerator evaporator fins with perforations on the surface allow circulating air to pass through the fin body. Part of the airflow passes through the perforations, forming a high-speed jet. The high-speed gas has a lower pressure, thus creating a local low-pressure zone on the leeward side of the perforations. On the windward side, the airflow is blocked or partially passes through, resulting in a slower flow velocity and higher pressure, forming a local high-pressure zone. The low-pressure zone downstream of the perforations attracts some air from the mainstream airflow to the rear of the perforations. Simultaneously, the edge structure of the perforations causes airflow separation. The pressure difference between the high-pressure and low-pressure zones, along with the airflow separation at the edge of the perforations, contributes to the flow around the perforations, resulting in more efficient heat exchange between the circulating air and the evaporator, leading to more energy-efficient and faster cooling.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides a refrigerator evaporator fin with surface-mounted baffles, which solves the problem that conventional refrigerator evaporator fins are all flat structures. While the dense arrangement of fins increases the contact area between the evaporator and the air, thus improving heat exchange efficiency, the heat dissipation efficiency is limited by relying solely on the contact area between the fins and the air. The new evaporator fin, when circulating air flows through the fin body 1, causes some airflow to pass through the baffles 14, forming a high-speed jet. The high-speed flowing gas has a low pressure, thus creating a local low-pressure area on the leeward side of the baffles 14. On the windward side of the baffles 14, the airflow is blocked or partially passes through, resulting in a relatively slower flow velocity and relatively higher pressure, forming a local high-pressure area. The low-pressure area downstream of the baffles 14 attracts some air from the mainstream airflow to the rear of the baffles 14. Simultaneously, the edge structure of the baffles 14 causes airflow separation. The pressure difference between the high-pressure and low-pressure areas, as well as the airflow separation at the edge of the baffles 14, work together to create a flow around the evaporator, resulting in more efficient heat exchange between the circulating air and the evaporator, achieving more energy-efficient and faster cooling.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This utility model discloses a refrigerator evaporator fin with turbulence holes on its surface.

[0024] Example 1: According to the appendix Figure 1-4 As shown, it includes several fin bodies 1, and mounting plates 3 are installed on both sides of the fin bodies 1. Evaporator tubes 2 are inserted between the two mounting plates 3 and the several fin bodies 1. Insertion holes and turbulence holes 14 are opened on the fin bodies 1, and the evaporator tubes 2 are inserted into the insertion holes.

[0025] When the circulating air flows through the fin body 1, some of the airflow passes through the turbulence hole 14, forming a high-speed jet. According to Bernoulli's principle, the pressure of the high-speed flowing gas is low. Therefore, a local low-pressure area will be formed on the leeward side of the turbulence hole 14, while on the windward side of the turbulence hole 14, the airflow is blocked or partially passes through, the flow velocity is relatively slow, and the pressure is relatively high, forming a local high-pressure area.

[0026] The turbulence holes 14 are arranged in a staggered pattern on the outer peripheral wall of the insertion hole. The arrangement of the holes affects the interaction and coverage of the eddies. The spacing between the holes in the inlet section of the turbulence holes 14 is smaller than the spacing between the holes in the outlet section.

[0027] The low-pressure area downstream of the turbulence hole 14 will attract some air from the mainstream airflow to the rear of the turbulence hole 14. At the same time, the edge structure of the turbulence hole 14 will cause the airflow to separate. The pressure difference between the high-pressure area and the low-pressure area, as well as the separation of the airflow at the edge of the turbulence hole 14, work together to cause the flow around the turbulence hole, making the heat exchange between the circulating air and the evaporator more complete, and achieving more energy-efficient and faster cooling.

[0028] Turbulence is extremely perpendicular to the flow direction, which allows fluid micro-particles with different temperatures to mix and exchange heat more fully. After the heat is conducted from the inside of the fin body 1 to the surface of the fin body 1, it can be carried away by the turbulent air more efficiently.

[0029] Connecting holes 12 are provided at the four corners of the fin body 1. Connecting rods 4 are inserted into the connecting holes 12, and several fin bodies 1 are installed through the connecting rods 4.

[0030] The plug rod 4 is inserted into the mounting plate 3. The outer peripheral wall of the mounting plate 3 is fixedly connected to the plug rod 4 with a fixing seat 41. The fixing seat 41 is slidably connected to the plug rod 4 and the fixing seat 41 is fixed to the plug rod 4 by bolts.

[0031] By installing the fixing base 41 and the plug rod 4, the mounting plate 3 is fixed to the outer peripheral wall of the plug rod 4. By adjusting the sliding of the mounting plate 3 on the plug rod 4, the distance between the two mounting plates 3 is adjusted, and at the same time the position of the fin body 1 on the plug rod 4 is adjusted, and the distance between the fin body 1 and the evaporator tube 2 is adjusted, so as to facilitate the adjustment of its heat dissipation effect.

[0032] Mounting plates 3 are fixedly connected to mounting bases 31 on both sides. Mounting bases 31 are provided with fixing holes. Mounting plates 3 are fixed to mounting frames through fixing holes on mounting bases 31, and fin bodies 1 and evaporator tubes 2 are installed.

[0033] Example 2: According to the appendix Figure 1-4 As shown, it includes several fin bodies 1. Mounting plates 3 are installed on both sides of the fin bodies 1. Evaporator tubes 2 are inserted between the two mounting plates 3 and the several fin bodies 1. The fin bodies 1 are provided with insertion holes and turbulence holes 14. The evaporator tubes 2 are inserted into the insertion holes. The turbulence holes 14 are distributed in a staggered layout on the outer peripheral wall of the insertion holes. The hole spacing of the inlet section of the turbulence holes 14 is smaller than the hole spacing of the outlet section.

[0034] A spring-loaded telescopic rod 5 is provided between adjacent fin bodies 1. When the spacing between the mounting plates 3 on both sides is adjusted, the position of the fin body 1 is adjusted. Under the action of the spring-loaded telescopic rod 5, the spacing between several adjacent fin bodies 1 is limited to be the same, and the evaporator tube 2 is effectively cooled through the fin body 1.

[0035] Mounting holes 13 are provided on both sides of the fin body 1, and spring-type telescopic rods 5 are installed in the mounting holes 13.

[0036] A sealing gasket 11 is installed in the insertion hole on the fin body 1. The sealing gasket 11 is in contact with the evaporator tube 2. The sealing gasket 11 protects the evaporator tube 2 and ensures the stable installation of the evaporator tube 2.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
