Description

Technical Field

[0001] This utility model relates to the field of outdoor unit technology for heat pump systems, and in particular to a condenser structure for an outdoor unit of a heat pump system. Background Technology

[0002] With global warming, air conditioner outdoor units are being used more frequently in high-temperature environments. To improve the condensation capacity of the outdoor unit, some air conditioners spray water mist, utilizing the heat of vaporization from the water mist's evaporation to enhance performance. However, spray devices that can evenly distribute water mist across the entire heat exchanger result in larger overall equipment sizes, requiring more installation space.

[0003] Patent application CN202211404000.9 discloses a condenser comprising heat pipes and fins. Multiple heat pipes are connected end-to-end in sequence. Fins are fitted onto the heat pipes to accelerate their cooling. The fins are connected sequentially and extend spirally downwards along the height of the heat pipes, forming a spiral flow channel. This spiral flow channel receives and guides the cooling water downwards, further enhancing the heat dissipation capacity of the fins. This eliminates the need for additional cooling devices such as spray systems; only a water supply pipe is required to supply cooling water to the spiral flow channel. This reduces the size of the outdoor unit and the installation space required.

[0004] Most existing fin modules are plate-shaped structures. When it is necessary to increase the heat dissipation area, the area of ​​the fin module is often increased horizontally to increase the overall area. However, the space of the heat pump outdoor unit is limited. Therefore, the area of ​​the fin module cannot be matched with the space of the heat pump outdoor unit and cannot be installed. Utility Model Content

[0005] The purpose of this invention is to provide a condenser structure for the outdoor unit of a heat pump system, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A condenser structure for an outdoor unit of a heat pump system includes a fin module, which includes a first heat exchange zone and a second heat exchange zone. The first heat exchange zone and the second heat exchange zone are perpendicular to each other and are integrally formed in an arc connection. The fin module is provided with multiple heat exchange tubes, and two adjacent heat exchange tubes are connected. A connector is installed at the end of one of the heat exchange tubes. The connector includes a connecting sleeve, and the connecting sleeve is detachably fitted with joint sleeves of different inner diameters.

[0008] Furthermore: a bent connecting pipe is provided between the heat exchange tubes, and a connector is installed at the end of the bent connecting pipe.

[0009] Furthermore, the first heat exchange zone and the second heat exchange zone each include multiple parallel and spaced heat dissipation fins, and two adjacent heat dissipation fins are formed with coaxially aligned heat dissipation holes, through which heat exchange tubes can pass.

[0010] Furthermore: the walls of the heat dissipation holes are formed with contact cylinders, through which heat exchange tubes can pass.

[0011] Furthermore: the inner ring wall of the connecting sleeve is formed with multiple first guide grooves along the axial direction, and the outer ring wall of the connector sleeve is formed with a first guide block that slides in cooperation with the first guide grooves along the axial direction.

[0012] Furthermore: the connector is connected to an inlet tube, and the inlet tube is fitted with an inlet head that is inserted into the connector sleeve.

[0013] Furthermore: the inner ring wall of the connector sleeve is formed with multiple second guide grooves along the axial direction, and the outer ring wall of the inlet head is formed with a second guide block that slides in conjunction with the second guide grooves.

[0014] Furthermore: the outer ring wall of the connecting sleeve is formed with an external thread structure, the end of the bent connecting pipe is slidably fitted with an external thread sleeve, and the inner ring wall of the external thread sleeve is formed with an internal thread structure that is threadedly engaged with the external thread structure of the connecting sleeve.

[0015] Furthermore, the fin module also includes a side fixing plate for fixing the heat dissipation fins. The side fixing plate has side positioning plates formed on both sides, which are parallel to the heat dissipation fins. The side fixing plate and the side positioning plates work together to position and fix the multiple heat dissipation fins.

[0016] Furthermore, the side fixing plate is formed with through holes that are coaxially aligned with the heat dissipation holes.

[0017] The beneficial effects of this utility model are as follows: During heat exchange, the heat from the heat exchange tube is transferred through the fin module to achieve heat dissipation; in addition, since the first heat exchange zone and the second heat exchange zone are perpendicular to each other and are integrally formed in an arc connection to form an L-shaped fin module, the fin module can be adapted to the shape of the internal space of the outdoor unit of the heat pump system, improving the space utilization rate; the connector of the heat exchange tube can be connected to various sizes of inlet connectors, enabling its application in different scenarios and improving its practicality.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1-5 As shown, a condenser structure for an outdoor unit of a heat pump system includes a fin module 1. The fin module 1 includes a first heat exchange zone 11 and a second heat exchange zone 12. The first heat exchange zone 11 and the second heat exchange zone 12 are perpendicular to each other and are integrally formed in an arc connection. The fin module 1 is provided with multiple heat exchange tubes 25, and two adjacent heat exchange tubes 25 are connected. A connector 2 is installed at the end of one of the heat exchange tubes 25. The connector 2 includes a connecting sleeve 21, and a joint sleeve 22 of different inner diameters is detachably fitted inside the connecting sleeve 21.

[0033] During heat exchange, the heat from the heat exchange tube 25 is transferred through the fin module 1 to achieve heat dissipation. In addition, since the first heat exchange zone 11 and the second heat exchange zone 12 are perpendicular to each other and are integrally formed in an arc shape to form an L-shaped fin module 1, the fin module 1 can be adapted to the shape of the indoor space of the outdoor unit of the heat pump system, thus improving the space utilization. The connector 2 of the heat exchange tube 25 can be connected to various sizes of inlet connectors, which can be used in different scenarios and improve practicality.

[0034] A bent connecting pipe 19 is provided between the heat exchange tubes 25, and a connector 36 is installed at the end of the bent connecting pipe 19. By inserting the connector 36 into the end of the bent connecting pipe 19, multiple heat exchange tubes 25 are formed into a continuous and sealed pipeline. The contact area between the liquid or gas in the heat exchange tubes 25 and the fin module 1 is increased, thereby increasing the heat exchange efficiency.

[0035] Furthermore, the first heat exchange zone 11 and the second heat exchange zone 12 each include a plurality of parallel and spaced heat dissipation fins 13. Adjacent heat dissipation fins 13 are formed with coaxially aligned heat dissipation holes 14, through which heat exchange tubes 25 can pass. The walls of the heat dissipation holes 14 are formed with contact cylinders 15, through which heat exchange tubes 25 can pass. After the heat exchange tube 25 is inserted into the heat dissipation hole 14 of the heat dissipation fin 13, the contact cylinder 15 contacts the outer annular wall surface of the heat exchange tube 25, increasing the surface contact area and further improving heat exchange efficiency during heat exchange.

[0036] Preferably, the fin module 1 further includes a side fixing plate 16 for fixing the heat dissipation fins 13. Side positioning plates 17, parallel to the heat dissipation fins 13, are formed on both sides of the side fixing plate 16. The side fixing plate 16, in conjunction with the side positioning plates 17, positions and fixes the multiple heat dissipation fins 13. This prevents the heat dissipation fins 13 from detaching, ensuring the integrity and unity of the fin module 1. The side fixing plate 16 has through holes 18 coaxially aligned with the heat dissipation holes 14, ensuring the guiding insertion of the heat exchange tubes 25. This further guides and positions adjacent heat dissipation fins 13, ensuring coaxial alignment and improving the integrity of the fin module 1.

[0037] One connector 2 is for inlet use, and the other connector 2 is for outlet use. Connector 2 is connected to an inlet pipe 3, and inlet pipe 3 is fitted with an inlet head 31 that inserts into connector sleeve 22. The inner annular wall of connector sleeve 21 is formed with multiple first guide grooves 23 along the axial direction, and the outer annular wall of connector sleeve 22 is formed with a first guide block 24 that slides with the first guide grooves 23 along the axial direction. When it is necessary to connect with inlet heads 31 of different sizes, connector sleeves 22 with different inner diameters can be inserted into connector sleeve 21. Insertion is achieved through the sliding engagement of the first guide grooves 23 and the first guide block 24, which changes the inner diameter of connector sleeve 21. At this time, the inlet head 31 of inlet pipe 3 can be connected with connector head 2 of the corresponding size.

[0038] Specifically, the inner ring wall of the connector sleeve 22 is formed with multiple second guide grooves 32 along the axial direction, and the outer ring wall of the inlet head 31 is formed with a second guide block 33 that slides with the second guide grooves 32 along the axial direction. When the connector sleeve 22 is connected and inserted into the inlet head 31, the inlet head 31 of the inlet tube 3 can achieve foolproof insertion through the second guide block 33 and the second guide grooves 32 of the inner ring wall of the connector sleeve 22.

[0039] Furthermore, the outer ring wall of the connecting sleeve 21 is formed with an external thread structure 35, and the end of the bent connecting pipe 19 is slidably fitted with an external thread sleeve 34. The inner ring wall of the external thread sleeve 34 is formed with an internal thread structure that threadedly engages with the external thread structure 35 of the connecting sleeve 21. After the inlet pipe 3 is connected to the connector 2, the external thread sleeve 34 located at the connector 2 can rotate and is screwed into the external thread structure 35 at the end of the bent connecting pipe 19 to achieve a knob connection, preventing the inlet pipe 3 from falling off after being connected to the connector 2, thereby ensuring the stability of the connection.

[0040] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
