[0038] In this embodiment, if Figure 1-Figure 6 As shown, the heat dissipation air duct assembly 1 is applied to an electric control box 2 of an integrated air conditioner, and includes a first air duct component 11 and a second air duct component 12 that are connected to each other.
[0039] The first air duct component 11 is used to cover the radiator 22 of the electric control box 2 , and the first air duct component 11 has a first air inlet portion 111 and a first air outlet portion 112 .
[0040] It can be understood that the first air inlet 111 is used to inhale heat dissipation airflow to dissipate heat from the radiator 22. The heat dissipation airflow can be airflow in the surrounding environment, for example, cooling airflow after being cooled by a condensing unit, or other airflow in the surrounding environment.
[0041] The second air duct member 12 has a second air inlet 121 and a second air outlet 122. The second air inlet 121 is connected to the first air outlet 112, and the flow cross-sectional area of the second air outlet 122 is smaller than that of the first air outlet 112.
[0042] It can be understood that the hot air flow after passing through the radiator 22 is connected to the air flow channel of the condensing unit of the integrated unit through the second air outlet 122.
[0043] In a specific embodiment, Figure 3 and Figure 6 As shown, the first air inlet 111 is disposed at the lower part of the first air duct component 11, and the first air outlet 112 is disposed at the upper part of the first air duct component 11. The second air inlet 121 is disposed at the lower part of the second air duct component 12, and the second air outlet 122 is disposed at the upper part of the second air duct component 12.
[0044] In one embodiment, if Figure 3 As shown, the first air outlet 112 has at least one first air outlet, and the second air outlet 122 has at least one second air outlet, and the total flow cross-sectional area of the second air outlet is smaller than the total flow cross-sectional area of the first air outlet.
[0045] In the present embodiment, by making the flow cross-sectional area of the air outlet of the second air duct component in the heat dissipation air duct assembly smaller than the flow cross-sectional area of the air outlet of the first air duct component, that is, setting the heat dissipation air duct to a structure with a gradually decreasing air outlet, according to the canyon effect, when the airflow of the wind field of the integrated air conditioner itself enters the second air duct component from the first air duct component, its flow velocity will increase, thereby being able to more effectively take away the heat of the inverter radiator on the electrical control box, thereby achieving a better heat dissipation and cooling effect.
[0046] In one embodiment, the flow cross-sectional area of the first air inlet 111 is greater than the flow cross-sectional area of the first air outlet 112. That is, the first air duct component is also configured to have a structure in which the flow cross-sectional area gradually decreases along the flow direction of the heat dissipation airflow, thereby further increasing the flow velocity of the hot airflow and enhancing the heat dissipation and cooling effect of the radiator.
[0047] Furthermore, the flow cross-sectional area of the second air inlet 121 is greater than the flow cross-sectional area of the second air outlet 122. That is, the second air duct component is also configured to have a structure in which the flow cross-sectional area gradually decreases along the flow direction of the heat dissipation airflow, thereby further increasing the flow velocity of the hot airflow and enhancing the heat dissipation and cooling effect of the radiator.
[0048] In one embodiment, the first air duct component 11 includes a main board 113 and a first side board 114 and a second side board 115 which are bent to the main board 113 .
[0049] Among them, Figure 3 As shown, the first side plate 114 and the second side plate 115 are located on the same side of the main board 113 and are both used to connect to the electric control box 2. An accommodating space for accommodating the radiator of the electric control box 2 is defined between the main board 113, the first side plate 114, the second side plate 115 and the electric control box 2.
[0050] It can be understood that the first side plate 114 includes two plates arranged opposite to each other along the flow direction of the heat dissipation airflow in the first air duct component 11, and the second side plate includes a plate arranged perpendicular to the flow direction of the heat dissipation airflow in the first air duct component 11. The first air inlet 111 is arranged on a side opposite to the second side plate 115, and the first air outlet 112 is arranged on the second side plate 115.
[0051] In one embodiment, if Figure 3 As shown, the first side panel 114 and the second side panel 115 are both provided with mounting folded edges 117 on the side away from the main board 113 , and the mounting folded edges 117 are both provided with connecting structures 116 , and the first side panel 114 and the second side panel 115 are respectively connected to the electric control box 2 via the connecting structures 116 .
[0052] In this embodiment, the connection structure 116 includes a connection hole 1161 and a connection member 1162 . The connection member 1162 is inserted into the connection hole 1161 to fix the first air duct component 11 to the electric control box 2 .
[0053] In one embodiment, if Figure 3 As shown, the heat dissipation duct assembly 1 also includes a waterproof strip 14, which is arranged between the installation folded edge 117 and the electrical control box 2. The waterproof strip 14 is provided with a through hole corresponding to the position of the connecting structure 116, and the connecting member 1162 passes through the connecting hole 1161 and the through hole on the waterproof strip 14 to fix the first duct component 11 and the electrical control box 2.
[0054] It can be understood that the waterproof strip 14 includes a waterproof rubber strip, and the electric control box 2 is provided with threaded holes corresponding to the connection holes 1161 and the through holes. By arranging the waterproof strip 14 to be attached to the back of the electric control box 2, the waterproof strip 14 is pressed tightly by the installation fold 117 of the heat dissipation air duct assembly 1 through the connection structure 116, which can prevent water from flowing in from the edge of the radiator, thereby ensuring the safety of the electrical components in the electric control box 2.
[0055] In one embodiment, if Figure 6 and Figure 9-10As shown, a limiting fold 124 is provided on one side of the second air duct component 12 close to the first air duct component 11, and the limiting fold 124 is engaged with the first air outlet 112. In one embodiment, the limiting fold 124 can be partially inserted into the first air outlet 112 to achieve engagement.
[0056] In a specific embodiment, a second air duct component mounting fold 125 may be further provided at the lower end of the second air duct component 12, and the second air duct component mounting fold 125 is fixed to the second side plate 115 by screws.
[0057] In one embodiment, if Figure 6 As shown, an air guide plate 123 is also provided in the second air duct component 12. The arrows indicate the flow direction of the airflow.
[0058] It can be understood that the direction in which the air guide plate 123 is arranged is along the direction from the second air inlet 121 of the second air duct component 12 to the second air outlet 122. By arranging the air guide plate 123, the airflow entering the second air duct component 12 can be made to reach the second air outlet 122 more smoothly along the air guide plate 123, thereby increasing the airflow speed and enhancing the heat dissipation effect. The air guide plate 123 may include an arc-shaped plate body with a certain curvature or a bent plate body with multiple bending angles.
[0059] In one embodiment, the heat dissipation air duct assembly 1 further includes a third air duct component 13 , the third air duct component 13 has a third air inlet portion 131 and a third air outlet portion 132 , and the third air inlet portion 131 is in communication with the second air outlet portion 122 .
[0060] In a specific embodiment, Figure 8 As shown, the third air inlet 131 is disposed at the lower portion of the third air duct component 13 , and the third air outlet 132 is disposed at the upper portion of the third air duct component 13 .
[0061] In one embodiment, a flow cross-sectional area of the third air outlet portion 132 is smaller than a flow cross-sectional area of the second air outlet portion 122 .
[0062] It can be understood that the third air outlet 132 is in communication with the internal air duct of the condensing unit of the integrated air conditioner.
[0063] In this embodiment, by making the flow cross-sectional area of the air outlet portion of the third air duct component in the heat dissipation air duct assembly smaller than the flow cross-sectional area of the air outlet portion of the second air duct component, the airflow entering the third air duct component from the second air duct component is further accelerated, thereby improving the overall flow speed of the airflow in the heat dissipation air duct assembly, and further improving the heat dissipation and cooling effect of the heat dissipation air duct assembly.
[0064] Furthermore, in one embodiment, the flow cross-sectional area of the third air inlet 131 is greater than or equal to the flow cross-sectional area of the third air outlet 132. That is, the third air duct component is also configured to have a structure in which the flow cross-sectional area gradually decreases along the flow direction of the heat dissipation airflow, thereby further increasing the flow velocity of the hot airflow and enhancing the heat dissipation and cooling effect of the radiator.
[0065] In the second aspect, an embodiment of the present application provides an air-conditioning electronic control box assembly, including a heat dissipation duct assembly 1 as described in any of the above items, and also including an electronic control box 2, the electronic control box 2 includes an electronic control box body 21 and a radiator 22, the electronic control box body 21 is configured to control the integrated air-conditioning unit, and the radiator 22 is configured to dissipate heat and cool the electronic control box body 21.
[0066] It can be understood that the frequency converter is arranged inside the electric control box 21, and the electric control box 21 controls the integrated air-conditioning unit including frequency conversion control and electrical signal control.
[0067] In one embodiment, if Figure 3 As shown, the bottom of the electric control box 21 is inclined toward a side away from the radiator 22 to form an inclined portion 211 .
[0068] It can be understood that the electric control box 21 is tilted toward the side away from the radiator 22, so that the space below the electric control box 21 is increased, thereby increasing the flow area of the airflow entering the heat dissipation duct assembly 1, and the oblique design also has a guiding effect, which can enable the airflow to enter the heat dissipation duct assembly 1 more smoothly.
[0069] In a third aspect, an embodiment of the present application provides an air conditioner, comprising a heat dissipation duct assembly 1 as described in any one of the above items or an air conditioner electronic control box assembly 2 as described in any one of the above items, and also comprising a condensing unit 4, the condensing unit comprising a water receiving tray 41, the condensing unit 4 is configured to condense and cool the hot air flow generated by the integrated air conditioner, and the water receiving tray is used to collect water generated by the condensing unit.
[0070] It is understandable that Figure 1 , Figure 7-Figure 11 As shown, the condensing unit 4 includes a condensing fan 42, a fan plate 44 and a water receiving tray 41, and an air flow channel 43 is formed between the condensing fan 42, the fan plate 44 and the water receiving tray 41. The direction indicated by the arrow represents the flow direction of the air flow.
[0071] In one embodiment, a vent 411 is provided on the water receiving tray 41 , and the second air outlet 122 is communicated with the vent 411 . It can be understood that the second air outlet 122 is indirectly communicated with the vent 411 through the third air duct component 13 .
[0072] In one embodiment, the edge of the vent 411 is also provided with a water retaining plate 412 and a water retaining folded edge 413 bent and connected to the water retaining plate 412, and the edge of the third air outlet portion 132 is provided with a third air duct component mounting folded edge 133, and the upper end of the third air duct component 13 is passed through the vent 411 and the third air duct component mounting folded edge 133 is fixed to the water retaining folded edge 413.
[0073] It can be understood that the water retaining plate 412 can prevent the water in the water receiving tray 41 from seeping downward and can play a role in the installation limit of the third air duct component 13, and the water retaining fold 413 thereon can be used to fasten the third air duct component 13. In one embodiment, the third air duct component installation fold 133 and the water retaining fold 413 can be fixed by screws.
