Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an outdoor air conditioning unit and a heat pump air conditioner. Background Technology

[0002] Currently, most outdoor units of common air source heat pump air conditioners, within their limited internal space, employ a method where the water module is placed separately on the top, bottom, or right side of the outdoor unit and isolated by sheet metal parts. However, this layout results in low integration of the equipment, low space utilization, and an increased size of the outdoor unit. To integrate the water module into the outdoor unit, improve overall equipment integration, and reduce size, the power supply box is typically placed horizontally inside the outdoor unit, and the water pump is placed externally on the outside of the outdoor unit to free up internal space. However, the horizontally placed power supply box obstructs part of the airflow, leading to performance degradation. Furthermore, maintenance is difficult when there is no extra space above the outdoor unit after installation, and external water pump placement has specific requirements for installation space and external environment, making installation and overall maintenance inconvenient.

[0036] In related technologies, the outdoor units of common air source heat pump air conditioners often utilize limited internal space by placing the water module separately on the top, bottom, or right side of the outdoor unit and isolating it with sheet metal parts. However, this layout results in low integration of the equipment, low space utilization, and increased size of the outdoor unit. To integrate the water module into the outdoor unit, improve overall integration, and reduce size, the power supply box is typically placed horizontally inside the outdoor unit, and the water pump is placed externally to free up internal space. However, the horizontally placed power supply box obstructs part of the airflow, leading to performance degradation. Furthermore, maintenance is difficult when there is no extra space above the outdoor unit after installation, and external water pump placement has specific requirements for installation space and external environment, making installation and overall maintenance inconvenient.

[0037] Therefore, this utility model embodiment provides an outdoor air conditioner unit and a heat pump air conditioner. According to this utility model embodiment, the outdoor air conditioner unit and heat pump air conditioner have high internal space utilization, are easy to assemble, feature modular component design for easy disassembly and maintenance, and have a vertically arranged power module to avoid obstructing the air duct.

[0038] Please see Figures 1 to 15The first aspect of this utility model provides an outdoor air conditioning unit, including a chassis 10, a front side panel 11, a rear side panel 12, a heat exchange assembly 20, a top cover 13, a sound insulation panel 16, a fan module 30, a water module 40, a compressor module, an expansion tank 60, and a power module 70; the chassis 10, the front side panel 11, the rear side panel 12, the heat exchange assembly 20, and the top cover 13 together form a closed shell, and the sound insulation panel 16 is disposed in the shell and divides the interior of the shell into a first chamber and a second chamber. The first chamber is used to house the fan module 30, and the second chamber is used to house the water module 40, the compression module, the expansion tank 60, and the power module 70. The water module 40 is installed on the front side of the chassis 10, the expansion tank 60 is installed on the rear side of the chassis 10, the compression module is installed between the water module 40 and the expansion tank 60, and the power module 70 is installed on the sound insulation plate 16 and is located above the water module 40.

[0039] In this embodiment of the invention, the front side plate 11, the rear side plate 12, and the heat exchange assembly 20 are each L-shaped. The front side plate 11, the rear side plate 12, and the heat exchange assembly 20 are arranged around the top surface of the chassis 10. The top cover 13 covers the top of the front side plate 11, the rear side plate 12, and the heat exchange assembly 20. A pipe side plate 14 is detachably installed on the side of the rear side plate 12. The pipe side plate 14 is located on the side wall of the second chamber and is adjacent to the water module 40.

[0040] Specifically, the water module 40 of this embodiment includes a plate heat exchanger bracket 41, a plate heat exchanger 42, a water pump 43, and a buffer rubber 44. The lower end of the plate heat exchanger bracket 41 is provided with an abutment portion 45, and the abutment portion 45 is provided with a first insertion port 46. A first pin 101 is provided on the chassis 10. The abutment portion 45 abuts against the chassis 10, and the first pin 101 is inserted into the first insertion port 46. The plate heat exchanger 42 is mounted on the plate heat exchanger bracket 41. The water pump 43 is located below the plate heat exchanger 42 and is connected to it. The pipe side plate 14 is arranged adjacent to the water pump 43. The buffer rubber 44 is detachably mounted on the plate heat exchanger bracket 41 and is located below the water pump 43. Furthermore, in this embodiment of the utility model, the plate heat exchanger bracket 41 is provided with a plate heat exchanger fixing plate 47, the plate heat exchanger fixing plate 47 is provided with a second socket 48, the rear side plate 12 is provided with a plate heat exchanger mounting part 103, the plate heat exchanger mounting part 103 is provided with a second pin 102, the second pin 102 is inserted into the second socket 48, and the plate heat exchanger fixing plate 47 is detachably mounted on the plate heat exchanger mounting part 103.

[0041] Furthermore, in this embodiment of the invention, the lower ends of the plate heat exchanger bracket 41 are respectively provided with supporting arms, and the bottom of each of the two supporting arms is provided with abutment portions 45. Each of the two supporting arms is provided with locking holes, and the sides of the buffer rubber 44 are respectively provided with buckles 49 that engage with the two locking holes. The plate heat exchanger 42 is provided with a first connector, and the water pump 43 is provided with a second connector. The first connector passes through the two supporting arms and extends outward through the pipe side plate 14, and the second connector extends outward through the pipe side plate 14. In addition, a third connector is provided below the plate heat exchanger 42, and the water pump 43 is provided with a water pipe connector connected to the third connector. A plate heat exchanger connector is provided above the plate heat exchanger 42, facing upward, to facilitate connection of the plate heat exchanger 42 with other modules.

[0042] Therefore, when assembling the water module 40 according to this embodiment of the invention, the two support arms of the plate heat exchanger bracket 41 first abut against the chassis 10, and the first insertion ports 46 on the two abutment portions 45 are quickly inserted into the chassis 10 by aligning them with the first pins 101 on the chassis 10. Then, the plate heat exchanger fixing plate 47 of the plate heat exchanger bracket 41 is fixed to the plate heat exchanger mounting portion 103. Specifically, the second insertion port 48 on the plate heat exchanger fixing plate 47 is quickly inserted into the plate heat exchanger mounting portion 103 by aligning it with the second pin 102 on the plate heat exchanger mounting portion 103, thereby achieving rapid assembly of the water module 40. In addition, when maintenance of the water pump 43 is required, the water pump 43 can be replaced simply by disassembling the front side plate 11 and the pipe side plate 14, without disassembling the plate heat exchanger bracket 41 or the plate heat exchanger 42, effectively improving the convenience of water pump 43 maintenance.

[0043] Furthermore, in this embodiment of the present invention, the power module 70 includes a first integrated circuit board, a second integrated circuit board, and heat dissipation fins 71. The first integrated circuit board and the second integrated circuit board are arranged in a T-shape. The first integrated circuit board is vertically arranged on the sound insulation plate 16, and the second integrated circuit board is vertically arranged above the water module 40. The heat dissipation fins 71 are arranged on the side of the first integrated circuit board away from the second integrated circuit board. The upper end of the sound insulation plate 16 has a through-hole for the heat dissipation fins 71 to pass through. The heat dissipation fins 71 pass through the through-hole and extend into the first chamber.

[0044] Therefore, when assembling the power module 70 of this embodiment, the first and second integrated circuit boards are arranged in a T-shape and vertically positioned above the water module 40. This not only does not affect the installation of the power module 70, but also prevents the power module 70 from blocking part of the airflow and causing performance degradation. Furthermore, the heat sink fins 71 can be used to cool it. In addition, the space behind the power module 70 can be used to arrange copper pipe systems for easy connection and assembly between the various modules. When maintenance is required on the power module 70, only the front panel 11 needs to be removed for inspection; the top cover 13 does not need to be removed, making it simple and convenient.

[0045] Furthermore, in this embodiment of the present invention, the compression module includes a compressor 50, sound insulation cotton 52, and a liquid reservoir. The compressor 50 is detachably mounted on the chassis 10, the sound insulation cotton 52 is sleeved on the compressor 50, and the liquid reservoir is detachably mounted on the chassis 10 and connected to the compressor 50. The chassis 10 is provided with a first insert rib 104, and the liquid reservoir is provided with a first slot 53, which is adapted to be inserted into the first insert rib 104. The chassis 10 is provided with a second insert rib 105, and the expansion tank 60 is provided with a second slot 61, which is adapted to be inserted into the second insert rib 105.

[0046] Therefore, when assembling the compression module of this utility model embodiment, firstly, the base of the compressor 50 is placed opposite the chassis 10 and the two are fixed together with bolts. Then, the sound insulation cotton 52 is fitted onto the compressor 50. Next, the liquid reservoir is quickly inserted and fixed onto the chassis 10. Then, the expansion tank 60 is quickly inserted onto the chassis 10. This allows both the compression module and the expansion tank 60 to be quickly assembled in the second chamber. The space above the compression module and the expansion tank 60 is used to accommodate the copper pipe system. The copper pipe system includes a three-way valve system 18, a four-way valve system 19, etc.

[0047] Furthermore, in this embodiment of the utility model, the fan module 30 includes a fan bracket 31, a fan motor 32, and a fan impeller 33. The fan bracket 31 is fixedly disposed in the first chamber, the fan motor 32 is fixedly disposed on the fan bracket 31, and the fan impeller 33 is rotatably disposed on the fan motor 32. An air outlet grille 15 is provided on the front side plate 11.

[0048] When assembling the outdoor unit of this air conditioner, firstly, the chassis 10 is taken out as the installation base. Three studs corresponding to the base of the compressor 50 are provided on the chassis 10. The base has through holes for the three studs to pass through. Then, the base is fitted onto the three studs and secured with nuts, thus fixing the compressor 50 to the chassis 10. Next, sound insulation cotton 52 is fitted onto the outside of the compressor 50. Finally, the heat exchange bracket 41 is inserted into the first pin 101 on the chassis 10. The heat exchanger bracket 41 is fixed to the chassis 10 by screws, thereby fixing the water module 40 to the chassis 10. The storage tank 51 is then inserted into the first insert rib 104 of the chassis 10 via its first slot 53 and secured with screws. The heat exchanger assembly 20 is then fixed to the chassis 10 by screws. Finally, the three-way valve system 18 and the four-way valve system 19 are assembled above the compression module, ensuring that the three-way valve system 18 and the four-way valve system 19 are properly aligned. Piping system 19 is connected to plate heat exchanger 42, compressor 50, and heat exchanger assembly 20 respectively. Expansion tank 60 is then inserted into the second insertion rod 105 of chassis 10 via its second slot 61 and fixed to chassis 10 with screws. Next, piping connecting storage tank 51 and capillary tube of expansion tank 60 are installed. Sound insulation panel 16 is then fixed to chassis 10 with screws. Power module 70 is then assembled onto sound insulation panel 16, and fan bracket 31 is fixed to heat exchanger assembly 20. Then, the fan motor 32 and fan impeller 33 are assembled in sequence; then the rear side plate 12 is assembled on the chassis 10, and the pipe side plate 14 is placed on one side of the water module 40. The plate heat exchange mounting part 103 of the rear side plate 12 is further inserted and fixed to the plate heat exchange fixing part of the plate heat exchange bracket 41.

Finally, the top cover 13 is installed to complete the assembly of the whole machine.

[0049] Therefore, according to the embodiment of the present utility model, the outdoor unit of the air conditioner is modularly designed by the fan module 30, water module 40, compressor module, expansion tank 60, and power module 70, and the interior of the outdoor unit is divided into a first chamber and a second chamber by the sound insulation plate 16, so as to facilitate the assembly of the modular components; specifically, the plate heat exchanger 42 is fixed on the plate heat exchanger bracket 41, and the first socket 46 and the second socket 48 on the plate heat exchanger bracket 41 are quickly inserted into the first pin 101 on the chassis 10 and the second pin 102 on the rear side plate 12, so that the plate heat exchanger bracket 41 can be easily and quickly assembled on the front side of the chassis 10. The water pump 43 is placed below the plate heat exchanger 42, and a buffer rubber 44 is connected to the water pump 43 by a buckle 49 below the water pump 43. The rear side plate 12 is provided with a pipe side plate 14 adjacent to the water pump 43, so as to facilitate the connection between the plate heat exchanger 42 and the water pump 43. The connector passes through the pipe side plate 14 and extends to the outside. In this way, when the water pump 43 needs to be maintained, only the front side plate 11 and the pipe side plate 14 need to be removed to maintain the water pump 43 without disassembling the entire water module 40. The compressor 50 and the liquid reservoir of the compression module are placed at the left rear and right rear of the water module 40, respectively. The expansion tank 60 can be quickly inserted into the second insertion rod 105 of the chassis 10 through its second slot 61 and is located behind the liquid reservoir. The power module 70 is installed vertically in a "T" shape above the water module 40. A copper pipe system is arranged on its rear side to connect the compression module, heat exchange assembly 20, water module 40 and expansion tank 60. This greatly improves the space utilization of the second chamber. Moreover, the power module 70 does not block the air duct. When the power module 70 needs to be maintained, only the front side plate 11 needs to be removed for repair or replacement.

The heat pump air conditioner according to this utility model has high internal space utilization, is easy to assemble, features a modular design for easy disassembly and maintenance, and has a power module 70 vertically arranged to avoid obstructing the airflow.

[0051] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the outdoor unit of the air conditioner and the heat pump air conditioner. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
