Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and in particular to an integrated double-row condenser structure. Background Technology

[0002] Existing dual-row condensers are formed by merging two single-row condensers. In this case, the fins of the two single-row condensers cannot be in the same plane during the merging process due to differences in the production process, resulting in a situation where they are intertwined.

[0003] During the operation of an air conditioner's outdoor unit, in order to deliver cooling or heating energy to the indoor unit, the outdoor unit requires the motor to rotate and the axial fan blades to exchange heat with the outside air through the fins. The air driven by the rotating fan blades, carrying dust, enters the outdoor unit's dual-row condenser for heat exchange. Due to the irregular arrangement of the fins in the dual-row condenser, dust can become trapped between the fins during heat exchange. This problem severely affects the outdoor unit's heat exchange, leading to a significant decrease in the air conditioner's cooling / heating capacity, increased power consumption, and increased noise. Poor heat dissipation causes the fan speed to increase, resulting in louder noise and potentially leading to compressor overheating or high-pressure protection malfunctions, affecting the compressor's lifespan and negatively impacting user comfort and overall quality. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an integrated double-row condenser structure that can solve the problems of poor heat exchange effect caused by dust and debris blockage in the middle of the condenser, resulting in poor comfort experience, high noise, high power consumption, short compressor life, and abnormal quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an integrated double-row condenser structure, including multiple fixed plates arranged in a transverse direction and a heat exchange structure arranged in a longitudinal direction. The heat exchange structure is provided with heat exchange tubes arranged along the length direction of the fixed plates. The heat exchange tubes of the heat exchange structure pass through the multiple fixed plates and are arranged in a double row. The heat exchange tubes of the heat exchange structure are parallel along the length direction of the fixed plates.

[0006] As a further improvement of this utility model: the plurality of fixing plates are arranged horizontally and uniformly in the horizontal direction, with a gap between two adjacent fixing plates.

[0008] As a further improvement of this utility model: the first heat exchange tube and the second heat exchange tube are arranged parallel to each other along the length direction of the fixed plate.

[0009] As a further improvement of this utility model: the first heat exchange tube and the second heat exchange tube are made of copper tubes.

[0010] As a further improvement of this utility model: the plurality of fixing plates are made of aluminum foil.

[0011] As a further improvement of this utility model: the first heat exchange tube and the second heat exchange tube form a plurality of heat exchange tube structures, the heat exchange tube structure including two adjacent copper tubes in the first heat exchange tube and a copper tube disposed opposite to the second heat exchange tube between the two adjacent copper tubes in the first heat exchange tube.

[0012] As a further improvement of this utility model: the copper tube of the second heat exchange tube partially covers the copper tube of the first heat exchange tube along the width direction of the fixed plate.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In existing technology, the original state of a double-row condenser, such as Figure 1-3 As shown, the original double-row condenser structure was formed by merging two single-row condensers. On the one hand, during the assembly process, the fin spacing is constant. Due to the need for consistent production process control and slight differences in fin spacing, the double-row fins are prone to interlacing, with one single-row fin blocking the spacing of the other. On the other hand, the interlaced fins are prone to accumulating dust and debris in the middle of the two single-row condensers.

[0029] Both of the above situations will seriously affect the heat exchange of the outdoor unit of the air conditioner, resulting in poor cooling / heating effect, increased power consumption, and increased noise. Poor heat dissipation of the outdoor unit will lead to increased fan speed and noise, and may also cause compressor overheating or high-pressure protection failures, affecting the service life of the air conditioner compressor. In addition, the original structure of merging two single-row condensers requires fixing blocks to fix the double-row condensers, which increases the cost of manpower and materials, and also increases the risk of production inconsistency.

[0030] Specifically: The original dual-row condenser was formed by merging two single-row condensers. In this case, due to differences in the manufacturing process, the fins of the two single-row condensers could not be aligned on the same plane during the merging process, resulting in a misaligned and interlocking structure. This leads to dust and debris getting trapped between the fins, causing blockages and hindering ventilation of the outdoor unit, resulting in poor heat dissipation. This problem has the following drawbacks:

[0031] Poor cooling performance and inadequate heat dissipation reduce the efficiency of the compressor when the air conditioner is running, preventing the indoor temperature from decreasing.

[0032] Increased power consumption means the air conditioner will run continuously to achieve the required cooling effect, thus increasing energy consumption.

[0033] Increased noise is caused by poor heat dissipation, which leads to increased fan speed and increased noise.

[0034] Air conditioner malfunctions, such as poor heat dissipation of the outdoor unit, may cause the compressor to overheat or malfunction due to high-pressure protection, thus affecting the lifespan of the air conditioner compressor.

[0035] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0036] Example 1:

[0037] like Figures 4 to 8 As shown, this utility model embodiment discloses an integrated double-row condenser structure, including multiple fixed plates 1 arranged in the transverse direction and a heat exchange structure arranged in the longitudinal direction. The heat exchange structure is provided with heat exchange tubes 2 arranged along the length direction of the fixed plates 1. The heat exchange tubes 2 of the heat exchange structure pass through the multiple fixed plates 1 in a double row and are parallel to the length direction of the fixed plates 1.

[0038] According to the integrated double-row condenser structure of this application, it mainly adopts a fixed plate 1 and multiple heat exchange tubes 2 connected to the fixed plate 1 along the length of the fixed plate 1. It optimizes the previous combination of two single-row condensers into a double-row condenser into an integrated, double-row thick condenser structure, which can achieve unobstructed heat exchange and improve the heat exchange efficiency of the outdoor unit. During the heat exchange process between the outdoor air flow and the condenser heat exchanger, the dust and debris carried by the flowing air can be directly flowed away from the fin gaps, avoiding dust and debris from being trapped in the condenser fin gaps. It can solve the problems of poor heat exchange effect caused by dust and debris blockage in the middle of the condenser, resulting in low capacity and high noise. In addition, the integrated structure eliminates the need for fixing the double-row condenser, reducing the labor and material costs in the production process.

[0039] In one embodiment of this invention, a plurality of the fixing plates 1 are arranged horizontally and uniformly in the horizontal direction, with a gap between adjacent fixing plates 1. The fixing plates 1 are arranged horizontally to form a plate assembly, and the gap between adjacent fixing plates 1 is to allow the rotating axial flow fan blades to rotate and exchange heat with the outside air through the fins formed by the fixing plates 1.

[0040] In one embodiment of this invention, the heat exchange structure includes a plurality of first heat exchange tubes 3 and second heat exchange tubes 4. The plurality of first heat exchange tubes 3 are connected to the fixing plate 1 along the length direction of the fixing plate 1, and the plurality of second heat exchange tubes 4 are connected to the fixing plate 1 along the length direction of the fixing plate 1. In this embodiment, the fixing plate 1, in addition to serving as heat exchange fins, also has the function of fixing the first heat exchange tubes 3 and second heat exchange tubes 4. By inserting the first heat exchange tubes 3 and second heat exchange tubes 4 into the fixing plate 1, the first heat exchange tubes 3 and second heat exchange tubes 4 are fixed to the fixing plate 1.

[0041] In one embodiment of this invention, the first heat exchange tube 3 and the second heat exchange tube 4 are arranged parallel to each other along the length of the fixed plate 1. The first heat exchange tube 3 and the second heat exchange tube 4 are parallel to each other to form a double-row heat exchange tube structure.

[0042] In one embodiment of this invention, the first heat exchange tube 3 and the second heat exchange tube 4 are made of copper. Copper tubes, as heat exchange elements in a condenser, offer significant advantages in heat exchange performance. Copper tubes have a high heat transfer coefficient, enabling them to transfer heat more effectively and improve the heat exchange efficiency of the condenser. Copper tube condensers have a compact and simple structure, are lightweight, and are relatively easy to manufacture, which helps reduce production costs.

[0043] In one embodiment of this invention, the plurality of fixing plates 1 are made of aluminum foil. Aluminum foil fins can significantly increase the heat transfer area per unit volume, making the heat exchange process more efficient.

[0044] In one embodiment of this invention, the first heat exchange tube 3 and the second heat exchange tube 4 form a plurality of heat exchange tube structures. Each heat exchange tube structure includes two adjacent copper tubes in the first heat exchange tube 3 and a copper tube disposed opposite to the second heat exchange tube 4 between the two adjacent copper tubes in the first heat exchange tube 3. Further, the copper tube of the second heat exchange tube 4 partially obscures the copper tube of the first heat exchange tube 3 along the width direction of the fixing plate 1. In this embodiment, since dust and debris are easily trapped between the double-row fins during the heat exchange process of the outdoor unit, when the copper tube of the second heat exchange tube 4 partially covers the copper tube of the first heat exchange tube 3, there is still a large gap between the two adjacent copper tubes in the first heat exchange tube 3. During the heat exchange process between the outdoor air and the condenser heat exchanger, the dust and debris carried by the flowing air can be directly discharged through the gap between the copper tubes. Furthermore, when there is airflow, the partially covered copper tube of the first heat exchange tube 3 will divert the airflow. While ensuring that dust and debris can be directly discharged through the gap between the fins, heat exchange can be effectively carried out, thereby improving the heat exchange efficiency of the condenser.

[0045] Example 2:

[0046] This utility model discloses an integrated double-row condenser structure, including multiple fixed plates 1 arranged laterally and a heat exchange structure arranged longitudinally. The heat exchange structure is provided with heat exchange tubes 2 arranged along the length direction of the fixed plates 1. The heat exchange tubes 2 of the heat exchange structure pass through the multiple fixed plates 1 in a double row and are parallel to the length direction of the fixed plates 1.

[0047] According to the integrated double-row condenser structure of this application, it mainly adopts a fixed plate 1 and multiple heat exchange tubes 2 connected to the fixed plate 1 along the length of the fixed plate 1. It optimizes the previous combination of two single-row condensers into a double-row condenser into an integrated, double-row thick condenser structure, which can achieve unobstructed heat exchange and improve the heat exchange efficiency of the outdoor unit. During the heat exchange process between the outdoor air flow and the condenser heat exchanger, the dust and debris carried by the flowing air can be directly flowed away from the fin gaps, avoiding dust and debris from being trapped in the condenser fin gaps. It can solve the problems of poor heat exchange effect caused by dust and debris blockage in the middle of the condenser, resulting in low capacity and high noise. In addition, the integrated structure eliminates the need for fixing the double-row condenser, reducing the labor and material costs in the production process.

[0048] In one embodiment of this invention, a plurality of the fixing plates 1 are arranged horizontally and uniformly in the horizontal direction, with a gap between adjacent fixing plates 1. The fixing plates 1 are arranged horizontally to form a plate assembly, and the gap between adjacent fixing plates 1 is to allow the rotating axial flow fan blades to rotate and exchange heat with the outside air through the fins formed by the fixing plates 1.

[0049] In one embodiment of this invention, the heat exchange structure includes a plurality of first heat exchange tubes 3 and second heat exchange tubes 4. The plurality of first heat exchange tubes 3 are connected to the fixing plate 1 along the length direction of the fixing plate 1, and the plurality of second heat exchange tubes 4 are connected to the fixing plate 1 along the length direction of the fixing plate 1. In this embodiment, the fixing plate 1, in addition to serving as heat exchange fins, also has the function of fixing the first heat exchange tubes 3 and second heat exchange tubes 4. By inserting the first heat exchange tubes 3 and second heat exchange tubes 4 into the fixing plate 1, the first heat exchange tubes 3 and second heat exchange tubes 4 are fixed to the fixing plate 1.

[0050] In one embodiment of this invention, the first heat exchange tube 3 and the second heat exchange tube 4 are arranged parallel to each other along the length of the fixed plate 1. The first heat exchange tube 3 and the second heat exchange tube 4 are parallel to each other to form a double-row heat exchange tube structure.

[0051] In one embodiment of this invention, the first heat exchange tube 3 and the second heat exchange tube 4 are made of copper. Copper tubes, as heat exchange elements in a condenser, offer significant advantages in heat exchange performance. Copper tubes have a high heat transfer coefficient, enabling them to transfer heat more effectively and improve the heat exchange efficiency of the condenser. Copper tube condensers have a compact and simple structure, are lightweight, and are relatively easy to manufacture, which helps reduce production costs.

[0052] In one embodiment of this invention, the plurality of fixing plates 1 are made of aluminum foil. Aluminum foil fins can significantly increase the heat transfer area per unit volume, making the heat exchange process more efficient.

[0053] In one embodiment of this invention, the first heat exchange tube 3 and the second heat exchange tube 4 form a plurality of heat exchange tube structures. Each heat exchange tube structure includes two adjacent copper tubes in the first heat exchange tube 3 and a copper tube positioned opposite the second heat exchange tube 4 between the two adjacent copper tubes in the first heat exchange tube 3. Further, the three copper tubes of the heat exchange tube structure are arranged in an equilateral triangle. In this embodiment, since dust and debris are easily trapped between the double-row fins during heat exchange in the outdoor unit, the equilateral triangle arrangement of the heat exchange tubes provides a larger heat transfer area per unit area and makes the fluid flow more uniform between the tubes, resulting in higher condenser heat exchange efficiency. Furthermore, dust and debris carried by the flowing air can be directly removed through the gaps between the equilateral triangle-arranged copper tubes. However, the relatively dense arrangement of the equilateral triangle-arranged copper tubes makes cleaning between them difficult.

[0054] In another embodiment of this invention, the three copper tubes of the heat exchange tube structure are arranged in an isosceles right-angled triangle. In this embodiment, compared to the equilateral triangle arrangement, the heat exchange tubes in the equilateral triangle arrangement have equal spacing, so more tubes can be arranged on the same tube sheet area. The isosceles right-angled triangle arrangement has fewer tubes and larger gaps, making it easier to clean the copper tubes. However, the heat exchange efficiency of the condenser is slightly lower than that of the equilateral triangle arrangement.

[0055] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
