Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an air conditioner. Background Technology

[0002] Inverter air conditioners use a radiator to dissipate heat from the electrical box, reducing the temperature rise of the controller components. In existing integrated inverter air conditioners, the radiator for the electrical box is often placed in the outdoor air duct, using air cooling. Specifically, the inverter electrical box is fixed to a partition, and the radiator is placed in the air intake duct of the outdoor heat exchange section, utilizing outdoor air for heat dissipation. However, to meet rain test requirements and prevent the electrical box from being exposed to rainwater and causing safety hazards, the electrical box and radiator are usually located away from the outdoor air intake grille. This results in poor heat dissipation. When the outdoor temperature is high, the increased load on the entire unit leads to higher air temperatures around the radiator, hindering effective heat dissipation and causing excessive temperature rise in components, ultimately rendering the entire unit inoperable.

[0003] To improve the heat dissipation effect of radiators and inverter electrical boxes in existing technologies, patent CN114087671A provides an air conditioner and its control method. This method involves setting up a heat dissipation duct to guide the cold air generated in the indoor heat exchange section into the outer heat exchange cavity of the outdoor heat exchange section, thereby dissipating heat from the inverter electrical box and reducing the surface temperature of the components. However, this arrangement causes the cold air generated in the indoor heat exchange section to be diverted, affecting the cooling effect of the indoor heat exchange section on the room. Summary of the Invention

[0004] This invention provides an air conditioner to solve the problem that the airflow of the heat dissipation channel in the prior art affects the cooling effect of the indoor heat exchange section.

[0005] To address the aforementioned problems, the present invention provides an air conditioner comprising: an outdoor heat exchange section having an external heat exchange cavity, the outdoor heat exchange section including an external heat exchanger, an inverter electrical box, and a radiator disposed within the external heat exchange cavity; the external heat exchange cavity being used for outdoor airflow to enter and exit for heat exchange with the external heat exchanger; the radiator being disposed on the inverter electrical box for heat dissipation of the inverter electrical box; an indoor heat exchange section for heat exchange with indoor airflow; and a heat dissipation duct, one end of which passes through the external heat exchange cavity and faces the radiator, the other end of which communicates with the indoor environment to guide indoor air to the radiator.

[0006] Furthermore, the indoor heat exchange section has a placement cavity for accommodating the heat dissipation duct, which passes through the placement cavity and is limited and matched with the inner wall of the placement cavity.

[0007] Furthermore, the heat dissipation duct includes a duct body, multiple first mounting parts and multiple second mounting parts. The multiple first mounting parts are distributed on the duct body along the extension direction or circumferential direction. The multiple second mounting parts are distributed on the outer surface of the indoor heat exchange part and / or the inverter electrical box. The multiple first mounting parts and multiple second mounting parts are connected one-to-one.

[0008] Furthermore, the first mounting part is a mounting ear with a mounting hole, and multiple mounting ears are spaced apart along the extension direction of the air duct body. The second mounting part is a threaded hole, and multiple threaded holes are correspondingly provided on the outer surface of the indoor heat exchange part and the outer surface of the frequency converter box. A mounting hole is threadedly connected to the corresponding threaded hole by a fastener.

[0009] Furthermore, the heat dissipation duct includes a duct body, which includes a first duct, a transition duct, and a second duct connected in sequence. The axis of the first duct and the axis of the second duct have an angle between them. The transition duct is an arc-shaped duct. The end of the first duct away from the transition duct passes through the placement cavity and is connected to the room. The end of the second duct away from the transition duct faces the radiator.

[0010] Furthermore, the air conditioner also includes a partition that separates the outdoor heat exchange section from the indoor heat exchange section. The partition has a through-hole that avoids the heat dissipation air duct. The through-hole and the placement cavity are matched and connected.

[0011] Furthermore, the air conditioner also includes a sealing element, and the inner wall of the opening is sealed to the outer wall of the heat dissipation duct through the sealing element.

[0012] Furthermore, the air conditioner also includes a housing and a panel. Both the outdoor heat exchange section and the indoor heat exchange section are located inside the housing. The panel is located on the side of the indoor heat exchange section away from the outdoor heat exchange section and is fixedly connected to the housing. The panel has a ventilation grille to connect the indoor unit and the heat dissipation duct.

[0013] Furthermore, the indoor heat exchange section includes an air inlet shell and an air outlet shell connected to each other. The air conditioner also includes a base. The air inlet shell is set on the base, and the air outlet shell is set on one side of the air inlet shell and spaced apart from the base in the height direction. The cavity inside the air inlet shell and the cavity inside the air outlet shell are connected. The area surrounded by the air outlet shell, the base and the air inlet shell forms a placement cavity. The heat dissipation air duct is limited and matched with the air outlet shell and the base.

[0014] Furthermore, the indoor heat exchange section also includes an internal heat exchanger and a wiring box. The internal heat exchanger is installed inside the cavity of the air inlet shell, and the wiring box is installed inside the placement cavity and is limited and matched with the base, air inlet shell, and air outlet shell. The heat dissipation duct and the wiring box are limited and matched on the side away from the air inlet shell.

[0015] According to the technical solution of the present invention, an air conditioner is provided, comprising: an outdoor heat exchange section having an external heat exchange cavity, the outdoor heat exchange section including an external heat exchanger, a frequency converter box, and a radiator disposed within the external heat exchange cavity, the external heat exchange cavity being used for outdoor airflow to enter and exit for heat exchange with the external heat exchanger, and the radiator being disposed on the frequency converter box for heat dissipation of the frequency converter box; an indoor heat exchange section for heat exchange with indoor airflow; and a heat dissipation duct, one end of which passes through the external heat exchange cavity and faces the radiator, and the other end of which communicates with the indoor environment to guide indoor air to the radiator. This design connects the two ends of the heat dissipation duct to the external heat exchange chamber and the indoor chamber, respectively. This avoids the situation in the prior art where the two ends of the heat dissipation duct are connected to the external heat exchange chamber and the indoor heat exchange section, respectively. The cooling of the environment where the frequency converter box and radiator are located is achieved by diverting the cold air generated by the indoor heat exchange section. The airflow in the room flows through the heat dissipation duct to the radiator located in the external heat exchange chamber, thereby dissipating heat from the frequency converter box, the radiator and the surrounding environment. This improves the heat dissipation effect on the frequency converter box while ensuring the heat exchange effect of the indoor heat exchange section on the indoor airflow.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention provides an air conditioner, including: an outdoor heat exchange section 10, the outdoor heat exchange section 10 having an external heat exchange cavity 11, the outdoor heat exchange section 10 including an external heat exchanger 12, an inverter electrical box 13 and a radiator 14 disposed in the external heat exchange cavity 11, the external heat exchange cavity 11 for allowing outdoor airflow to enter and exit to exchange heat with the external heat exchanger 12, the radiator 14 being disposed on the inverter electrical box 13 to dissipate heat from the inverter electrical box 13; an indoor heat exchange section 20 for exchanging heat with indoor airflow; and a heat dissipation duct 30, one end of the heat dissipation duct 30 passing through the external heat exchange cavity 11 and facing the radiator 14, the other end of the heat dissipation duct 30 communicating with the indoor environment to guide indoor air to the radiator 14.

[0032] In this embodiment, the two ends of the heat dissipation duct 30 are connected to the external heat exchange cavity 11 and the indoor space, respectively. This avoids the situation in the prior art where the two ends of the heat dissipation duct 30 are connected to the external heat exchange cavity 11 and the indoor heat exchange section 20, respectively. The environment where the frequency converter box 13 and the radiator 14 are located is cooled by the diversion of cold air generated by the indoor heat exchange section 20. The airflow in the room flows through the heat dissipation duct 30 to the radiator 14 located in the external heat exchange cavity 11, thereby achieving heat dissipation for the frequency converter box 13, the radiator 14 and the surrounding environment of the radiator 14. This improves the heat dissipation effect of the frequency converter box 13 while ensuring the heat exchange effect of the indoor heat exchange section on the indoor airflow.

[0033] Specifically, the external heat exchange cavity 11 has an inlet air duct and an outlet air duct. The frequency converter box 13 and the heat sink 14 are located on the inlet air duct side. During the heat exchange process of the outdoor heat exchange section 10, the outdoor airflow enters the external heat exchange cavity 11 through the inlet air duct. During the airflow, the frequency converter box 13, the heat sink 14, and the environment in which the two devices are located dissipate heat, realizing the outdoor environment's air-cooled heat dissipation of the frequency converter box 13 and ensuring the reliability of the frequency converter box 13's operation. At the same time, the heat dissipation duct 30 realizes the indoor environment's heat dissipation of the frequency converter box 13 and the heat sink 14, further improving the heat dissipation effect of the frequency converter box 13, the heat sink 14, and the environment in which the two devices are located, avoiding the situation where the frequency converter box 13 malfunctions due to excessive temperature rise, or the situation where the ambient temperature of the heat sink 14 is high, resulting in poor heat dissipation effect of the heat sink 14 on the frequency converter box 13.

[0034] like Figure 1 and Figure 2 As shown, the indoor heat exchange section 20 has a placement cavity 21 for accommodating the heat dissipation duct 30, which passes through the placement cavity 21 and is limited and matched with the inner wall of the placement cavity 21.

[0035] In this embodiment, the heat dissipation duct 30 is installed on the indoor heat exchange section 20, facilitating communication between both ends of the heat dissipation duct 30 and the indoor and outdoor heat exchange chambers 11, respectively. The heat dissipation duct 30 and the placement chamber 21 are matched to ensure the reliability of the installation of the heat dissipation duct 30. Optionally, the heat dissipation duct 30 can also be installed on both the indoor heat exchange section 20 and the outdoor heat exchange section 10.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, the heat dissipation duct 30 includes a duct body 31, multiple first mounting portions 32, and multiple second mounting portions 33. The multiple first mounting portions 32 are distributed along the extension direction or circumferential direction of the duct body 31 on the duct body 31, and the multiple second mounting portions 33 are distributed on the outer surface of the indoor heat exchange section 20 and / or the inverter electrical box 13. The multiple first mounting portions 32 and the multiple second mounting portions 33 are connected one-to-one. This arrangement facilitates the fixing of the heat dissipation duct 30, prevents the heat dissipation duct 30 from shifting after installation, and ensures the stability of the installation.

[0037] Specifically, the first mounting part 32 is a mounting ear with mounting holes. Multiple mounting ears are spaced apart along the extension direction of the air duct body 31. The second mounting part 33 is a threaded hole. Multiple threaded holes are correspondingly provided on the outer surface of the indoor heat exchange part 20. Each mounting hole is threadedly connected to its corresponding threaded hole by a fastener. This arrangement facilitates the machining of the first mounting part 32 and the second mounting part 33. Specifically, in this embodiment, there are two mounting ears and two threaded holes. The fastener is a screw. Each screw passes through the mounting hole on one mounting ear and is threadedly connected to its corresponding threaded hole. The screwing directions of the two screws are the same in the horizontal direction.

[0038] Furthermore, the heat dissipation duct 30 includes a duct body 31, which includes a first duct 311, a transition duct 312, and a second duct 313 connected in sequence. The axis of the first duct 311 and the axis of the second duct 313 form an angle. The transition duct 312 is an arc-shaped duct. One end of the first duct 311, away from the transition duct 312, passes through the placement cavity 21 and communicates with the room. The other end of the second duct 313, away from the transition duct 312, faces the radiator 14. This arrangement facilitates the heat dissipation duct 30 in guiding the airflow in the room to the radiator 14, achieving accurate heat dissipation for the environment surrounding the radiator 14 and the inverter electrical box 13. Specifically, in this embodiment, both mounting ears are located on the same side of the first air duct 311. One mounting ear is located on the outer wall of the first air duct 311, and the axis of the mounting hole on the mounting ear is parallel to the width direction of the first air duct 311. The other mounting ear is located at the end of the first air duct 311 away from the transition air duct 312, and the axis of the mounting hole on the mounting ear is parallel to the length direction of the first air duct 311.

[0039] like Figure 1 and Figure 5As shown, the air conditioner also includes a partition 40, which separates the outdoor heat exchange section 10 and the indoor heat exchange section 20. The partition 40 has a through-hole 41 that avoids the heat dissipation duct 30. The through-hole 41 and the placement cavity 21 are mutually restrictive and connected. This arrangement ensures the reliability of the separation between the indoor heat exchange section 20 and the outdoor heat exchange section 10, and the through-hole 41 ensures the reliability of the installation of the heat dissipation duct 30. Specifically, the two sides of the partition 40 are the indoor heat exchange section 20 and the outdoor heat exchange section 10, respectively. The inverter electrical box 13 is mounted on the partition 40 and located inside the outer heat exchange cavity 11. The through-hole 41 on the partition 40 is connected to the cavity of the indoor heat exchange section 20 and the outer heat exchange cavity 11, respectively, to prevent the heat dissipation duct 30 from being blocked by the partition 40, thus preventing the connection between the indoor and outdoor heat exchange cavities 11. Specifically, the inverter electrical box 13 is fixed to the partition 40 by a screw structure or a snap-fit ​​structure, such as... Figure 2 and Figure 3 As shown, two second mounting parts 33 are respectively installed on the indoor heat exchange part 20 and the partition plate 40.

[0040] Specifically, the air conditioner also includes a sealing element, and the inner wall of the through-hole 41 is sealed to the outer wall of the heat dissipation duct 30 through the sealing element. This arrangement ensures the reliability of the separation between the external heat exchange cavity 11 and the indoor heat exchange section 20 of the air conditioner. Specifically, the sealing element can be a sponge, velvet, or sealing putty, etc.

[0041] like Figure 6 As shown, the air conditioner also includes a housing and a panel 50. Both the outdoor heat exchange section 10 and the indoor heat exchange section 20 are housed within the housing. The panel 50 is located on the side of the indoor heat exchange section 20 facing away from the outdoor heat exchange section 10 and is fixedly connected to the housing. The panel 50 has a ventilation grille 51 to connect the indoor unit and the heat dissipation duct 30. This arrangement ensures the reliability of the connection between the heat dissipation duct 30 and the indoor unit, preventing the end of the heat dissipation duct 30 from being blocked after the housing and panel 50 are installed, thus ensuring the reliability of the heat dissipation duct 30 for the inverter electrical box 13. Specifically, the ventilation grilles 51 are distributed on the bottom and side walls of the panel, and each grille has multiple spaced ventilation openings, allowing airflow from the indoor environment to be drawn into the heat dissipation duct 30 through these openings.

[0042] like Figure 2As shown, the indoor heat exchange unit 20 includes an air inlet shell 22 and an air outlet shell 23 connected to each other. The air conditioner also includes a base 60. The air inlet shell 22 is disposed on the base 60, and the air outlet shell 23 is disposed on one side of the air inlet shell 22 and spaced apart from the base 60 in the height direction. The cavity inside the air inlet shell 22 is connected to the cavity inside the air outlet shell 23. The area surrounded by the air outlet shell 23, the base 60 and the air inlet shell 22 forms a placement cavity 21. The heat dissipation duct 30 is limited and matched with the air outlet shell 23 and the base 60.

[0043] In this embodiment, the cavities of the air inlet shell 22 and the air outlet shell 23 are connected. The cavity inside the air inlet shell 22 is a heat exchange cavity, and the cavity inside the air outlet shell 23 is an air outlet cavity. The side of the air inlet shell 22 facing the room has an air inlet, and the side of the air outlet shell 23 facing the room has an air outlet. The airflow in the room enters the heat exchange cavity through the air inlet and undergoes heat exchange. The airflow after heat exchange flows to the adjacent air outlet cavity and is discharged from the air outlet. Specifically, as shown... Figure 2 As shown, the air outlet cavity and the placement cavity 21 are located on the right side of the heat exchange cavity. The placement cavity 21 is located below the air outlet cavity and is spaced apart from both the air outlet cavity and the heat exchange cavity. The radiator 14 is located below the inverter box 13, avoiding the situation in the prior art where the radiator 14 is connected to the air outlet cavity, resulting in the diversion of the heat exchange airflow output from the air outlet cavity. Furthermore, as shown... Figure 2 and Figure 3 As shown, the heat dissipation duct 30 is installed into the placement cavity 21 from right to left and is matched with the base 60 and the air outlet shell 23. Two second mounting parts 33 (threaded holes) are provided on the side of the air outlet shell 23 away from the outdoor heat exchange section 10 and on the side of the partition plate 40 facing the outdoor heat exchange section 10. The two first mounting parts 32 (mounting ears) of the heat dissipation duct installed in the placement cavity 21 are fixedly connected by fasteners and the two second mounting parts 33 (threaded holes) to fix the heat dissipation duct 30.

[0044] The air conditioner is a modular air conditioner, the outdoor heat exchange section 10 is the outdoor unit of a split air conditioner, and the indoor heat exchange section 20 is the indoor unit of a split air conditioner; or, the air conditioner is a split air conditioner, the outdoor heat exchange section 10 is the outdoor unit of a split air conditioner, and the indoor heat exchange section 20 is the indoor unit of a split air conditioner.

[0045] like Figure 1 and Figure 2As shown, the indoor heat exchange section 20 also includes an internal heat exchanger and a wiring box 24. The internal heat exchanger is disposed within the cavity of the air inlet shell 22, and the wiring box 24 is disposed within the placement cavity 21 and is mutually restrictive with the base 60, the air inlet shell 22, and the air outlet shell 23. The heat dissipation duct 30 and the wiring box 24 are mutually restrictive with each other on the side opposite to the air inlet shell 22. This arrangement ensures the reliability of the installation of the heat dissipation duct 30. Specifically, the internal heat exchanger is disposed within the air inlet shell 22 and performs heat exchange treatment on the airflow flowing in from the air inlet. The wiring box 24 is disposed within the placement cavity 21 and is mutually restrictive with the air outlet shell 23, the air inlet shell 22, the base, and the partition 40. Figure 2 As shown, the heat dissipation duct 30 enters the placement cavity 21 from right to left and is limited and matched with the side of the wiring electrical box 24 away from the air inlet shell 22.

[0046] In summary, the present invention provides an air conditioner, which further includes axial flow fan blades disposed within the outdoor heat exchange section 10. When the air conditioner is running, the axial flow fan blades located within the indoor heat exchange section 20 continuously draw in air from the air inlet duct of the outdoor heat exchange chamber 11. The drawn-in air undergoes heat exchange through the outdoor heat exchanger 12. During its flow, the air drawn in from the outside will have a heat dissipation effect on the inverter electrical box 13 and radiator 14 located on the outdoor side. To prevent the air conditioner from increasing its load when the outdoor ambient temperature is high and during cooling operation, thus causing the air temperature around the radiator 14 to rise and resulting in heat exchange between the radiator 14 and the outdoor air on the inverter... When the heat dissipation effect of the electrical box 13 deteriorates, the air conditioning unit's heat dissipation duct 30 connects the indoor and outdoor heat exchange chambers 11. Due to the negative pressure generated during the process of the axial fan blades drawing in air, the air in the indoor environment is introduced into the outdoor heat exchange chamber 11 through the heat dissipation duct 30 under the action of this negative pressure. One end of the heat dissipation duct 30 is directly opposite the radiator 14 located below the inverter electrical box 13, so that the lower temperature indoor air can effectively dissipate heat from the radiator, thereby reducing the temperature rise of the controller components and further improving the heat dissipation effect of the inverter electrical box 13, allowing the air conditioner to operate normally at a higher frequency.
