Description

Technical Field

[0001] This utility model relates to a V-shaped condenser structure. Background Technology

[0002] Currently, air-cooled chiller units that use V-fin heat exchangers as condensers all suffer from uneven air velocity and volume at the condenser's air inlet. This results in different heat exchange effects in the upper, middle, and lower zones of the fin heat exchanger, leading to unstable refrigerant conditions at the condenser outlet and hindering stable control of the entire unit.

[0003] Existing solutions mostly involve changing the height of the finned condenser inlet to alter the refrigerant flow rate in different areas, combined with the wind speed in that area to optimize heat exchange, or optimizing the angle of the V-shaped finned condenser to optimize the inlet airflow field to achieve the goal of optimizing heat exchange. However, optimizing the angle of the V-shaped finned condenser still presents the problem of uneven inlet airflow caused by the inverted V-shaped spatial angle. Since a finned condenser generally has only one inlet, and the length of this pipe is directly proportional to the number of tubes in each row of finned heat exchange tubes, when the refrigerant is distributed from the inlet to each heat exchange tube along the length of the pipe, simply changing the height of the finned condenser inlet is insufficient to match the complex inlet air velocity field on the windward side of the finned heat exchanger.

[0004] Therefore, a V-type condenser structure is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the existing defects by providing a V-type condenser structure that ensures stable outlet refrigerant condition, fully utilizes the heat exchange area, and facilitates overall unit control.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a V-shaped condenser structure, comprising a first V-shaped fin group and a second V-shaped fin group, wherein an inverted V-shaped region is formed between the first V-shaped fin group and the second V-shaped fin group, and an upper heat exchange zone, a middle heat dissipation zone and a lower heat dissipation zone are respectively provided within the inverted V-shaped region;

[0007] A first fan is installed above the first V-shaped fin assembly, and a second fan is installed above the second V-shaped fin assembly.

[0008] Preferably, the upper heat exchange zone is 10% to 25% of the entire inverted V-shaped region; the fin spacing of the first V-shaped fin group and the second V-shaped fin group on both sides of the upper heat exchange zone is 1.3 to 1.5 mm.

[0009] Preferably, the central heat dissipation area is 20% to 35% of the entire inverted V-shaped area; the fin spacing of the first V-shaped fin group and the second V-shaped fin group on both sides of the central heat dissipation area is 1.5 to 1.7 mm.

[0010] Preferably, the lower heat dissipation area is 30% to 45% of the entire inverted V-shaped area; the fin spacing of the first V-shaped fin group and the second V-shaped fin group on both sides of the lower heat dissipation area is 1.7 to 2.0 mm.

[0011] Preferably, the fin height of the first V-shaped fin group and the second V-shaped fin group on both sides of the upper heat exchange zone is 1.0 to 1.2 mm.

[0012] Preferably, the fin height of the first V-shaped fin group and the second V-shaped fin group on both sides of the central heat dissipation area is 1.5 to 1.7 mm.

[0013] Preferably, the fin height of the first V-shaped fin group and the second V-shaped fin group on both sides of the lower heat dissipation area is 0.8 to 1.0 mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This V-type condenser structure optimizes the uneven air intake in the installation space caused by the fixed installation method of the V-type finned condenser. By analyzing the different air intake conditions in different areas of the finned heat exchanger, the fin shape and fin spacing are designed in a targeted manner to balance the heat exchange in the upper, middle and lower areas, thereby solving the problem of uneven heat exchange caused by the same finned heat exchanger when installed in a V-shape. This makes the outlet refrigerant state stable, makes full use of the heat exchange area, and facilitates the overall control of the unit. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 A V-shaped condenser structure includes a first V-shaped fin group 1 and a second V-shaped fin group 2, with an inverted V-shaped region 3 formed between the first V-shaped fin group 1 and the second V-shaped fin group 2. An upper heat exchange zone 4, a middle heat dissipation zone 5 and a lower heat dissipation zone 6 are respectively arranged in the inverted V-shaped region 3. A first fan 7 is arranged above the first V-shaped fin group 1 and a second fan 8 is arranged above the second V-shaped fin group 2.

[0021] Specifically, the upper heat exchange zone 4 is 10% to 25% of the entire inverted V-shaped zone 3; the fin spacing of the first V-shaped fin group 1 and the second V-shaped fin group 2 on both sides of the upper heat exchange zone 4 is 1.3 to 1.5 mm.

[0022] Specifically, the upper heat exchange zone 4 is closer to the fan and can be air-intaken from both sides of the V-shaped condenser. The air blows from the bottom to the top, so the air velocity in the upper heat exchange zone 4 is the highest. There may be some air volume that is wasted without participating in heat exchange. To address this, the fin spacing in this area is reduced to increase the heat exchange area and balance the air volume. Generally, the height of the upper heat exchange zone 4 is about 10% to 25% of the entire finned heat exchanger. Generally, the fin spacing in the upper heat exchange zone 4 is about 1.3 to 1.5 mm.

[0023] Specifically, the fin height of the first V-shaped fin group 1 and the second V-shaped fin group 2 on both sides of the upper heat exchange zone 4 is 1.0 to 1.2 mm.

[0024] Specifically, generally speaking, air-cooled finned condensers mostly use corrugated or vented fins. The taller the fins, the greater the airflow resistance and the higher the turbulence; conversely, the smaller the fins, the lower the airflow resistance and the lower the turbulence. By changing the fin spacing and using different fin heights, the heat exchange effect of the entire condenser can be enhanced and balanced. Generally, a value between 0.8 and 1.4 mm can be used. In the upper heat exchange zone 4, while reducing the fin spacing, the fin height is increased to 1.0 to 1.2 mm to increase airflow resistance.

[0025] Specifically, the central heat dissipation zone 5 is 20% to 35% of the entire inverted V-shaped zone 3; the fin spacing of the first V-shaped fin group 1 and the second V-shaped fin group 2 on both sides of the central heat dissipation zone 5 is 1.5 to 1.7 mm.

[0026] Specifically, the distance between the central heat dissipation zone 5 and the fan is moderate, and the air blows from the bottom to the top. Therefore, the air velocity and air volume in the central heat dissipation zone 5 are moderate. Considering the relationship between air volume and fin resistance, and with the aim of enhancing heat exchange, it is designed with a general fin spacing and selects a fin type with moderate heat exchange efficiency. Generally, the height of the central heat dissipation zone 5 is about 20% to 35% of the entire finned heat exchanger. Generally, the fin spacing of the central heat dissipation zone 5 is about 1.5 to 1.7 mm.

[0027] Specifically, the fin height of the first V-shaped fin group 1 and the second V-shaped fin group 2 on both sides of the central heat dissipation area 5 is 1.5 to 1.7 mm.

[0028] Specifically, generally speaking, air-cooled finned condensers mostly use corrugated or vented fins. The taller the fins, the greater the airflow resistance and the higher the turbulence; conversely, the smaller the fins, the lower the airflow resistance and the lower the turbulence. By changing the fin spacing and using different fin heights, the heat exchange effect of the entire condenser can be enhanced and balanced. A value generally between 0.8 and 1.4 mm is suitable. In the central heat dissipation zone 5, the fin spacing is reduced while increasing the airflow resistance, resulting in a fin height of 1.5 to 1.7 mm.

[0029] Specifically, the lower heat dissipation area 6 is 30% to 45% of the entire inverted V-shaped area 3; the fin spacing of the first V-shaped fin group 1 and the second V-shaped fin group 2 on both sides of the lower heat dissipation area 6 is 1.7 to 2.0 mm.

[0030] Specifically, the lower heat dissipation zone 6 is further away from the fan, and air can enter from both sides of the V-shaped condenser. The air blows from the bottom to the top, so the air velocity in the lower heat dissipation zone 6 is the lowest. To address this, the fin spacing in this area is increased to reduce air resistance, thereby increasing airflow and enhancing heat exchange in this area. Generally, the height of the lower heat dissipation zone 6 is about 30% to 45% of the entire finned heat exchanger. Generally, the fin spacing in the lower heat dissipation zone 6 is about 1.7 to 2.0 mm.

[0031] Specifically, the fin height of the first V-shaped fin group 1 and the second V-shaped fin group 2 on both sides of the lower heat dissipation area 6 is 0.8 to 1.0 mm.

[0032] Specifically, generally speaking, air-cooled finned condensers mostly use corrugated or vented fins. The taller the fins, the greater the airflow resistance and the higher the turbulence; conversely, the smaller the fins, the lower the airflow resistance and the lower the turbulence. By changing the fin spacing and using different fin heights, the overall heat exchange effect of the condenser can be enhanced. A value generally between 0.8 and 1.4 mm is suitable. In the lower heat dissipation zone 6, the fin height is 0.8 to 1.0 mm to increase airflow resistance while reducing the fin spacing.

[0033] This V-type condenser structure optimizes the uneven airflow in the installation space caused by the fixed installation method of V-type finned condensers. By analyzing the different airflow conditions in different areas of the finned heat exchanger, the fin shape and fin spacing are designed to balance the heat exchange in the upper, middle and lower areas. This solves the problem of uneven heat exchange caused by the same finned heat exchanger when installed in a V-type configuration, ensuring stable refrigerant conditions at the outlet and making full use of the heat exchange area, which is beneficial for the overall control of the unit.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
