Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a heat exchanger with a windbreak structure and an integrated air conditioner. Background Technology

[0002] In existing technology, air conditioners have heat exchangers, which can be used as evaporators and condensers. A heat exchanger generally includes heat exchange tubes, fins, and end plates for connection. The heat exchange tubes pass between two end plates, and the fins are spaced apart between the two end plates. The heat exchange tubes pass through the fins, and the end plates are connected to the air conditioner casing via a connecting structure. The thin fin design can improve the surface area-to-volume ratio and promote heat exchange, but it has low structural strength and is prone to deformation. Therefore, the fins are generally protected within the end plates, meaning the sides of the heat exchange fins are located inside the sides of the end plates. After the sides of the end plates are installed against the air conditioner casing, there is a gap between the fins and the casing. When the fan starts blowing air for heat exchange, in addition to flowing between the heat exchange fins, the air also flows out through the aforementioned gaps. This portion of the airflow does not fully pass through the heat exchange fins, resulting in a loss of this heat exchange airflow and affecting heat exchange efficiency. Utility Model Content

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] It should be noted that, ideally, during heat exchange in a heat exchanger, air should completely penetrate the narrow channels designed between the fins, allowing for sufficient convective heat exchange between the airflow and the surfaces of the fins and heat exchange tubes. However, due to the presence of gaps protecting the fins, some airflow does not flow through the fin gaps, which require overcoming higher resistance but offer the optimal heat exchange efficiency. Instead, it flows directly through the relatively low-resistance space between the fin side and the end plate side, creating a short circuit. This results in a significant portion of the airflow that should be involved in effective heat exchange being lost, failing to effectively contact the high-temperature or low-temperature surfaces of the fins and heat exchange tubes. This air leakage not only directly reduces the overall heat exchanger efficiency, requiring longer operating times or larger airflow volumes to achieve the same temperature control effect, thus increasing additional energy consumption, but also may lead to uneven local airflow, causing some fin areas to be insufficiently cooled or heated, and even causing unnecessary condensate retention, localized frost formation on the fin surface, or uneven thermal stress, thereby affecting the long-term stability and reliability of the system.

[0035] Reference Figures 1 to 4 According to a first aspect of the present invention, a heat exchanger with a windbreak structure includes a mounting plate 100, heat exchange tubes 200, heat exchange fins 300, and a windbreak plate 400. Two mounting plates 100 are arranged in parallel. Each mounting plate 100 is rectangular and has a contact positioning portion 110 on its long side. The heat exchange tubes 200 pass through the two mounting plates 100. Multiple heat exchange fins 300 are provided and spaced apart between the two mounting plates 100. Each heat exchange fin 300 is parallel to the mounting plate 100, and the heat exchange tube 200 passes through the heat exchange fin 300. There is a clearance distance 500 between the side of the heat exchange fin 300 near the abutment positioning part 110 and the abutment positioning part 110. A baffle plate 400 is installed between the two mounting plates 100 and located on the upper and / or lower side of the heat exchange fin 300, with one side extending to the abutment positioning part 110 and the other side extending to the heat exchange fin 300. The baffle plate 400 can block the clearance distance 500 between the mounting plate 100 and the heat exchange fin 300, preventing the heat exchange airflow from entering laterally through the clearance distance 500 and instead allowing it to flow only through the heat exchange fin 300, ultimately improving heat exchange efficiency.

[0036] Specifically, the mounting plates 100 can be vertically spaced, with their long sides extending vertically. Heat exchange tubes 200 are arranged in a serpentine pattern through two mounting plates 100, resulting in multiple tube segments between the two plates. Heat exchange fins 300 can be rectangular, with heat exchange tubes 200 also passing through them. The heat exchange fins 300 are arranged relatively closely between the two mounting plates 100, with the gaps between them forming efficient heat exchange channels. The abutment positioning part 110 is used to abut or connect with the air conditioner's casing, and the casing's air vents are opposite the heat exchange fins 300, allowing air to flow through these efficient heat exchange channels and exit from the air vents. However, the side of the heat exchange fins 300 closest to the abutment positioning part 110 needs to be recessed into the mounting plate 100 to avoid interference with the casing. In this case, a clearance space is formed between the sides of all heat exchange fins 300 and the abutment positioning part 110. During heat exchange, air can flow directly from the upper and lower sides of the mounting plate 100 through the clearance space and outwards without passing through the heat exchange fins 300. However, with the baffle plate 400 installed, this flow path is blocked, allowing air to flow only through the aforementioned high-efficiency heat exchange channel, thereby improving heat exchange efficiency and reducing energy consumption.

[0037] Reference Figures 2 to 4 In some embodiments of this utility model, a mounting structure is provided between the wind deflector 400 and the mounting plate 100. The mounting structure includes a snap-fit ​​component 610 and fasteners. The wind deflector 400 can be snapped onto the mounting plate 100 and positioned by the snap-fit ​​component 610, so that the fasteners can securely connect the wind deflector 400 and the mounting plate 100. Specifically, the fasteners can be bolts. The wind deflector 400 is detachably mounted on the mounting plate 100. During installation, the wind deflector 400 can first be snapped onto the mounting plate 100 by the snap-fit ​​component 610 for pre-positioning, and then secured to the mounting plate 100 by bolts, resulting in a firm assembly and convenient operation.

[0038] Reference Figures 2 to 4 In some embodiments of this utility model, the wind deflector 400 has a first folded edge 410 on the side near the mounting plate 100. The first folded edge 410 has a first mounting hole 411, and the mounting plate 100 has a second mounting hole 120 corresponding to the first mounting hole 411. Fasteners can fasten the wind deflector 400 to the mounting plate 100 through the first mounting hole 411 and the second mounting hole 120. Specifically, the wind deflector 400 can be bent on both sides near the mounting plate 100 to form the first folded edge 410. The first folded edge 410 is parallel to the mounting plate 100. During installation, the first folded edge 410 abuts against the mounting plate 100. The first mounting hole 411 can be opened on the first folded edge 410, and the mounting plate 100 has a corresponding second mounting hole 120, so that bolts can pass through the first mounting hole 411 and the second mounting hole 120 for connection.

[0039] Reference Figures 2 to 3 In some embodiments of this utility model, the snap-fit ​​assembly 610 includes a slot 611 and a buckle 612. The slot 611 is located on the side of the mounting plate 100 away from the abutment positioning part 110, and the buckle 612 is located on the wind deflector 400. When the buckle 612 is engaged in the slot 611, the first mounting hole 411 and the second mounting hole 120 can be aligned. Specifically, the slot 611 is located on the side of the mounting plate 100, with its opening facing away from the abutment positioning part 110. During installation, the wind deflector 400 can be inserted from the extension direction of the short side of the mounting plate 100, and the buckle 612 can be inserted into the slot 611 for positioning. After positioning, the first mounting hole 411 and the second mounting hole 120 can be automatically aligned, and then the bolts can be connected. With the above structure, there is no need to manually adjust the alignment of the mounting holes, making operation convenient.

[0040] Reference Figures 2 to 4 In some embodiments of this utility model, the baffle plate 400 has a second folded edge 420 on the side near the heat exchange fins 300. The second folded edge 420 is perpendicular to the heat exchange fins 300 and abuts against the side of the heat exchange fins 300. A buckle 612 is provided on the side of the second folded edge 420 near the mounting plate 100. Specifically, the second folded edge 420 can abut against and be positioned with the upper or lower side of the heat exchange fins 300, and the second folded edge 420 can increase the contact area with the heat exchange fins 300, reducing pressure to avoid damaging the heat exchange fins 300. At the same time, the second folded edge 420 can also increase the windproof area. The buckle 612 can be provided on both sides of the second folded edge 420. During installation, the second folded edge 420 can be abutted against and positioned with the side of the heat dissipation fins. At this time, the buckle 612 and the slot 611 can be aligned, which is convenient for snapping and operation.

[0041] Reference Figures 1 to 3 In some embodiments of this utility model, the abutting and positioning part 110 includes a third folded edge part 111, which is perpendicular to the mounting plate 100. Specifically, the mounting plate 100 can be bent to form the third folded edge part 111, which is convenient for processing. The third folded edge part 111 can abut and position with the air conditioner housing.

[0042] Reference Figures 2 to 4 In some embodiments of this utility model, the wind deflector 400 has a fourth folded edge 430 on its side near the abutting positioning part 110. The fourth folded edge 430 is parallel to the third folded edge 111, and the fourth folded edge 430 has a connecting hole 431. Specifically, the wind deflector 400 can also abut against the air conditioner housing through the fourth folded edge 430, and be connected to the housing through the connecting hole 431 by screws. The connection of the wind deflector 400 is more secure, and the gap between the wind deflector 400 and the housing can be reduced.

[0043] Reference Figures 2 to 4 In some embodiments of this invention, the baffle plate 400 is inclined toward the heat exchange fins 300 from one side of the mounting plate 100 abutting and positioning portion 110 to the other side. The inclined baffle plate 400 can reduce airflow resistance.

By employing the heat exchanger described above, the heat exchange airflow can fully flow through the heat exchange fins 300 for heat exchange, thereby improving heat exchange efficiency and reducing energy consumption.

[0045] Reference Figure 5 In some embodiments of this utility model, the heat exchanger with a windproof structure is configured as a condenser, and also includes a housing 710, a compressor 720, a throttling device 730, and an evaporator 740. The compressor 720, condenser, throttling device 730, and evaporator 740 are connected in sequence. A partition plate 750 is provided inside the housing 710, which can divide the housing 710 into a first cavity 760 and a second cavity 770. The housing 710 is also provided with a first air inlet 761 and a first air outlet 762 communicating with the first cavity 760, and a second air inlet 771 and a second air outlet 772 communicating with the second cavity 770. The second cavity 770 is provided with a condenser, a compressor 720, and a throttling device 730. The abutting positioning part 110 abuts against the second air outlet 772. The evaporator 740 is disposed in the first cavity 760 and is located between the first air inlet 761 and the first air outlet 762. It is understandable that a fan can be installed at the first air inlet 761 or the first air outlet 762. Similarly, a fan can be installed at the second air inlet 771 and the second air outlet 772, and the first air inlet 761, the first air outlet 762 and the second air inlet 771 and the second air outlet 772 can be located on opposite sides.

[0046] In the above structure, there is no need to set up separate indoor and outdoor units, which can achieve an integrated structure. Furthermore, the second air inlet 771 and the second air outlet 772 can simultaneously dissipate heat from the compressor 720 and the condenser, making the space more compact.
