Description

Technical Field

[0001] This utility model relates to the field of air conditioning heat exchanger technology, specifically to a heat dissipation fin for a heat exchanger with a built-in turbulence structure. Background Technology

[0002] An air conditioner is a commonly used air conditioning unit. The radiator of an air conditioner is an important component of the air conditioning system and is usually installed on the outdoor unit. This design is to better utilize the external environment for heat dissipation. The air conditioner radiator consists of heat dissipation pipes and aluminum heat dissipation fins. The heat dissipation pipes are responsible for transferring the heat generated by the condenser to the heat dissipation fins, and then the heat is dissipated into the air through the large area of ​​heat dissipation fins and the assistance of the fan. Existing heat dissipation fins are mainly divided into straight fins, corrugated fins, and spiral fins. Among them, straight fins are the most common type. Their fins are arranged in a straight line perpendicular to the axis of the pipe body. They have the advantages of simple and practical design, low processing cost, and easy cleaning and maintenance, but the heat exchange efficiency is relatively low. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heat exchanger fin with a built-in turbulence structure. Through the design of the turbulence structure, the contact area between the heat exchange fin and the air is increased, thereby improving the heat dissipation effect.

[0004] The technical solution adopted in this utility model is a heat exchanger fin with a built-in turbulence structure, including a heat dissipation tube. The front side of the heat dissipation tube is connected to a first heat dissipation fin. A partition is connected to the middle of the vertical part of the first heat dissipation fin. The bottom two sides of the partition are provided with a first inner flow guide plate. The top of the partition is connected to a flow divider plate. The side plates on both sides of the flow divider plate are provided with an air inlet, an air outlet, and a baffle. The two ends of the first heat dissipation fin are connected to a ventilation tube. The ventilation tube is provided with a second inner flow guide plate. The front side of the ventilation tube is provided with an air passage hole. The front end of the ventilation tube is connected to a wind baffle plate. The upper and lower ends of the heat dissipation tube are connected to an outer flow guide plate. The rear side of the heat dissipation tube is connected to a second heat dissipation fin. The second heat dissipation fin is provided with an internal heat dissipation fin. The upper and lower walls of the second heat dissipation fin are provided with wind baffles. The upper and lower walls of the second heat dissipation fin are provided with air inlets. The side wall of the rear end of the second heat dissipation fin is provided with an air outlet.

[0005] The first heat dissipation fin has a concave shape in the middle of its horizontal direction, and its concave surface is semi-circular. The outer surfaces of the upper and lower ends of the first heat dissipation fin are arc-shaped, and the first heat dissipation fin is a solid structure.

[0006] The side plates on both sides of the diversion plate are connected to the first heat dissipation fin. The diversion plate and the concave part on the left side of the first heat dissipation fin form a left air intake groove, and the diversion plate and the concave part on the right side of the first heat dissipation fin form a right air intake groove.

[0007] The side plates and partitions on both sides of the diverter plate form a left heat dissipation cavity and a right heat dissipation cavity.

[0008] The second heat dissipation fin is a hollow structure.

[0009] The top surfaces of the adjacent wind deflectors are in contact with each other.

[0010] The vertical cross-sections of the left and right air intake slots are semi-circular, and their sizes are half the size of the air passage holes, coinciding with the side positions of the air passage holes.

[0011] The wind baffle is located outside the air passage, with the edge of its concave surface in the middle of the horizontal direction fitting with the semi-circular side of the air passage, and the edges of its upper and lower convex surfaces fitting with the edges of the convex surfaces on both sides of the first heat dissipation fin.

[0012] The built-in heat dissipation fins have a conical cross-section and are solid.

[0013] The beneficial effects of this utility model are as follows: In this utility model, a diversion plate is provided at the vertical center of the first heat dissipation fin. When the fan blows, the diversion plate can divert part of the air to the left and right air intake slots on both sides. The concave left and right air intake slots increase the contact area and contact time between the air and the first heat dissipation fin, thereby improving the heat dissipation efficiency of the first heat dissipation fin. At the same time, when the air in the left and right air intake slots passes through the ventilation pipes on both sides, the air velocity in the ventilation pipes increases, resulting in a decrease in pressure, which speeds up the airflow through the ventilation pipes and facilitates the rapid discharge of hot air.

[0014] In this invention, the protrusions at the upper and lower ends of the first heat dissipation fin allow the remaining air to blow over the upper and lower ends of the first heat dissipation fin, carrying away the heat from the upper and lower ends of the first heat dissipation fin. At the same time, after passing through the outer air guide plate, the air can enter the interior of the second heat dissipation fin under the combined action of the baffle plate and the air inlet, and be discharged from the air outlet under the action of the conical structure of the built-in heat dissipation fin, thereby improving the overall heat dissipation efficiency of the second heat dissipation fin and the heat dissipation pipe.

[0015] In this invention, when the air blown by the fan is diverted by the splitter plate, the air inlet allows some of the air to enter the left and right heat dissipation chambers respectively, and then it is discharged from the air outlet, taking away the heat and being discharged together with the air in the left and right air intake slots, thereby improving the heat dissipation effect of the first heat dissipation fins; the baffle can prevent the air from entering the left and right heat dissipation chambers from the air outlet.

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Referring to the accompanying drawings, a heat exchanger fin with a built-in turbulence structure includes a heat dissipation tube 1. A first heat dissipation fin 2 is connected to the front side of the heat dissipation tube 1. A partition 3 is connected to the vertical center of the first heat dissipation fin 2. First inner air guide plates 4 are provided on both sides of the bottom of the partition 3. A flow divider plate 5 is connected to the top of the partition 3. An air inlet 6, an air outlet 7, and a baffle 8 are provided on the side plates of both sides of the flow divider plate 5. Ventilation pipes 9 are connected to both ends of the first heat dissipation fin 2. A second inner air guide plate 10 is provided inside the ventilation pipes 9. The ventilation pipe 9 has an air passage hole 11 on one side of its front end. The front end of the ventilation pipe 9 is connected to a wind baffle plate 12. The upper and lower ends of the heat dissipation pipe 1 are connected to external air guide plates 13. The rear side of the heat dissipation pipe 1 is connected to a second heat dissipation fin 14. The second heat dissipation fin 14 has an internal heat dissipation fin 15. The upper and lower walls of the second heat dissipation fin 14 are both provided with wind baffle plates 16. The upper and lower walls of the second heat dissipation fin 14 are both provided with air inlets 17. The rear side wall of the second heat dissipation fin 14 is provided with an air outlet 18.

[0026] The first heat dissipation fin 2 has a concave shape in the middle of its horizontal direction, and its concave surface is semi-circular. The outer surfaces of the upper and lower ends of the first heat dissipation fin 2 are arc-shaped, and the first heat dissipation fin 2 is a solid structure.

[0027] The side plates of the diversion plate 5 are connected to the first heat dissipation fin 2. The diversion plate 5 and the concave part on the left side of the first heat dissipation fin 2 form a left air intake groove 19, and the diversion plate 5 and the concave part on the right side of the first heat dissipation fin 2 form a right air intake groove 20.

[0028] The side plates of the diverter plate 5 and the partition plate 3 form a left heat dissipation cavity 21 and a right heat dissipation cavity 22.

[0029] The second heat dissipation fin 14 is a hollow structure.

[0030] The top surfaces of the adjacent wind deflectors 16 are in contact with each other.

[0031] The vertical cross-sections of the left air intake slot 19 and the right air intake slot 20 are semi-circular, and their sizes are half the size of the air passage hole 11, and they coincide with the side position of the air passage hole 11.

[0032] The wind baffle 12 is located outside the air passage 11. The edge of its concave surface in the middle of the horizontal direction is in contact with the semi-circular side of the air passage 11, and the edges of its upper and lower convex surfaces are in contact with the edges of the convex surfaces on both sides of the first heat dissipation fin 2.

[0033] The built-in heat dissipation fins 15 have a conical cross-section and are solid.

[0034] When the heat exchanger with its built-in turbulence structure is in use, when the fan blows air to the first heat exchange fin 2, some of the air will be diverted by the diverter plate 5 and flow into the left air intake slot 19 and the right air intake slot 20, and then enter the ventilation pipe 9 through the air passage 11, and then be discharged from the ventilation pipe 9 to carry away the heat from the first heat exchange fin 2.

[0035] After the air is diverted from the splitter plate 5, some of the air will enter the left heat dissipation cavity 21 and the right heat dissipation cavity 22 from the air inlets 6 on both sides of the splitter plate 5, and will be blown out from the air outlet 7 to carry away the heat in the left heat dissipation cavity 21 and the right heat dissipation cavity 22. It will also enter the ventilation pipe 9 through the air hole 11 and be discharged.

[0036] When the fan blows air onto the first heat sink fin 2, some of the air will be diverted by the diverter plate 5, and the remaining air will be blown over the protrusions at the top and bottom ends of the first heat sink fin 2, and after passing through the outer guide plate 13, it will enter the second heat sink fin 14 through the air inlet holes 17 at the top and bottom ends, and then blow over the top and bottom ends of the built-in heat sink fin 15, and finally be discharged from the air outlet holes 18 on the side of the second heat sink fin 14, thus carrying away the heat inside the second heat sink fin 14 and the heat on the built-in heat sink fin 15.

[0037] In this invention, a diversion plate 5 is provided at the vertical center of the first heat dissipation fin 2. When the fan blows, the diversion plate 5 can divert part of the air to the left air intake slot 19 and the right air intake slot 20 on both sides. The concave left air intake slot 19 and the right air intake slot 20 increase the contact area and contact time between the air and the first heat dissipation fin 2, thereby improving the heat dissipation efficiency of the first heat dissipation fin 2. At the same time, when the air in the left air intake slot 19 and the right air intake slot 20 passes through the ventilation pipes 9 on both sides, the air velocity in the ventilation pipes 9 increases, resulting in a decrease in pressure, which speeds up the airflow through the ventilation pipes 9 and facilitates the rapid discharge of hot air.

[0038] In this invention, the protrusions at the upper and lower ends of the first heat dissipation fin 2 allow the remaining air to blow over the upper and lower ends of the first heat dissipation fin 2, which can carry away the heat at the upper and lower ends of the first heat dissipation fin 2. At the same time, after passing through the outer air guide plate 13, the air can enter the interior of the second heat dissipation fin 14 under the combined action of the baffle plate 16 and the air inlet 17, and be discharged from the air outlet 18 under the action of the conical structure of the built-in heat dissipation fin 15, thereby improving the overall heat dissipation efficiency of the second heat dissipation fin 14 and the heat dissipation pipe 1.

[0039] In this invention, when the air blown by the fan is diverted by the splitter plate 5, the air inlet 6 allows some of the air to enter the left heat dissipation cavity 21 and the right heat dissipation cavity 22 respectively, and then it is discharged from the air outlet 7, taking away the heat and being discharged together with the air in the left air duct 19 and the right air duct 20, thereby improving the heat dissipation effect of the first heat dissipation fin 2; the baffle 8 can prevent the air from entering the left heat dissipation cavity 21 and the right heat dissipation cavity 22 from the air outlet 7.
