[0030] Compared with the prior art, the beneficial effects of the present invention are:
[0031] In the technical solution of the present invention, after the indoor air enters the housing through the indoor air inlet of the housing, it enters the first air duct through the port of the air duct housing communicating with the indoor air inlet. The air in the first air duct is led out of the first air duct through the port of the air duct housing communicating with the indoor air outlet, and then is led out of the housing through the indoor air outlet and flows into the room. The indoor air exchanges heat with the first heat exchanger during the process of entering and being led out of the first air duct. In particular, in this solution, the first air guiding opening of the air duct housing communicates with the second air duct of the electronic control box, so that the electronic control box can utilize the air flow in the air duct housing for heat dissipation. Compared with the solution of setting an additional air supply component to dissipate heat from the electronic control box in the related art, in this solution, there is no need to set a special air supply component for the electronic control box, reducing the number of parts and lowering the cost while enabling the electronic control box to achieve good heat dissipation.
[0032] Furthermore, although this solution uses the airflow in the first air duct for heat dissipation, in this solution, the electronic control box is not directly arranged inside the air duct housing. Instead, the airflow is led out from the first air duct through the first air guide opening to dissipate heat from the electronic control box located outside the air duct housing. Compared with the solution of directly arranging the electronic control box in the first air duct of the air duct housing, the electronic control box in this solution has less obstruction to the airflow in the first air duct, the airflow in the first air duct circulates more smoothly, and the air outlet efficiency of the air conditioner is higher. Moreover, since the electronic control box does not disrupt the flow state of the airflow in the first air duct, the consistency of the airflow led out from the indoor air outlet is better, which is more conducive to the fine control of the airflow led out from the indoor air outlet.
[0033] In addition, in this solution, the box body of the electronic control box defines a second air duct, and the airflow in the first air duct can enter the second air duct (i.e., enter the interior of the electronic control box) from the first air guide opening. Compared with the structure in which the airflow from the first air guide opening is led out and then guided to the outer wall of the electronic control box, the heat dissipation effect is better.

[0053] The realization, functional features and advantages of the object of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments
[0054] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0055] The electronic control box of the air conditioner is used to control the internal electrical components of the air conditioner. Since the electronic control box has a relatively high temperature during operation, it is necessary to cool it down. In the related art, an independent fan is provided to cool the electronic control box, resulting in a relatively high cost. The applicant considered that the heat exchange air flow inside the air conditioner can be used to dissipate heat from the electronic control box, so that there is no need to provide a dedicated air supply component for dissipating heat from the electronic control box, thereby reducing the cost. In view of this, initially in this application, the electronic control box is directly disposed in the indoor heat exchange air duct inside the air conditioner (the indoor air enters the indoor heat exchange air duct inside the air conditioner for heat exchange and then is led out to the room), and this solution can utilize the air flow in the indoor heat exchange air duct to dissipate heat from the electronic control box. Then, it was subsequently found that in the above solution, on the one hand, after the electronic control box is disposed in the indoor heat exchange air duct, since the electronic control box needs to be electrically connected to the electronic components outside the air duct housing, the wires electrically connected to the electronic control box in the air duct need to extend out of the air duct, and it is difficult to arrange the wires; on the other hand, the electronic control box will hinder the flow of the air flow in the indoor heat exchange air duct, resulting in a reduction in the air outlet efficiency of the air conditioner, and the air flow in the indoor heat exchange air duct becomes turbulent and has poor consistency after flowing through the electronic control box, which is not conducive to the precise control of the air outlet.
[0056] In view of this, refer to Figures 1-10 , this embodiment provides an air conditioner 10, which includes a housing assembly 100, a first heat exchanger 200, and an electronic control box 400. Specifically refer to Figures 1-4 , the air conditioner 10 may further include components such as a second heat exchanger 300, a compressor, and an air supply assembly 500. The second heat exchanger 300 is connected to the first heat exchanger 200, and the heat exchange medium circulates between the first heat exchanger 200 and the second heat exchanger 300; the compressor is used to compress the heat exchange medium flowing in the first heat exchanger 200 and the second heat exchanger 300; the air supply assembly 500 may include a first air supply part 510 and a second air supply part 520. The first air supply part 510 is used to drive the air flow to exchange heat with the first heat exchanger 200, and the second air supply part 520 is used to drive the air flow to exchange heat with the second heat exchanger 300.
[0057] The air conditioner 10 can be integrally arranged or split-type arranged. When the air conditioner 10 is integrally arranged, components such as the electronic control box 400, the first heat exchanger 200, the second heat exchanger 300, the compressor, and the air supply assembly 500 are all disposed in a housing 110. When the air conditioner 10 is split-type arranged, the air conditioner 10 may include two housings. The first heat exchanger 200 and the second heat exchanger 300 may be respectively disposed in two different housings, and an intermediate pipeline passing through the two housings is connected between the first heat exchanger 200 and the second heat exchanger 300. For the convenience of description, hereinafter, the air conditioner 10 being an integrally arranged air conditioner 10 is taken as an example for illustration.
[0058] The housing assembly 100 includes a housing 110 and an air duct housing 120 located inside the housing 110. The specific shape and component composition of the housing 110 depend on actual requirements. Refer to Figure 1 and Figure 5 , exemplarily, the outer shape of the housing 110 is generally a hexahedron. The housing 110 includes a front panel, a rear panel, an upper panel, a lower panel, a left panel, and a right panel. There is an arc transition between the front panel and the top panel of the housing 110. The housing 110 is formed by assembling three main parts. Specifically, the housing 110 includes an upper frame 111, a lower frame 112, and a back panel 113. The upper frame 111 of the housing 110 includes the upper panel, the upper half of the left panel, the upper half of the right panel, and the upper half of the front panel. The lower frame 112 of the housing 110 includes the lower panel, the lower half of the left panel, the lower half of the right panel, and the lower half of the front panel. The back panel 113 is respectively connected to the rear sides of the upper frame 111 and the lower frame 112. After the upper frame 111, the lower frame 112, and the back panel 113 of the housing 110 are connected (specifically, it can be a threaded connection), they enclose an internal space for accommodating other components of the air conditioner 10.
[0059] Refer to Figures 1-4 , the housing 110 is provided with an indoor air inlet 1121 and an indoor air outlet 1122. The indoor air enters the housing 110 through the indoor air inlet 1121 and exchanges heat with the first heat exchanger 200, and then is discharged to the indoor through the indoor air outlet 1122, thereby realizing the heat exchange treatment of the indoor air. The specific layout positions of the indoor air inlet 1121 and the indoor air outlet 1122 depend on actual requirements. In this embodiment, both the indoor air inlet 1121 and the indoor air outlet 1122 are arranged on the same panel of the housing 110. Specifically, both the indoor air inlet 1121 and the indoor air outlet 1122 are arranged on the lower panel of the lower frame 112. Thus, the air conditioner 10 takes in air from the bottom and discharges air from the bottom. In other embodiments, the indoor air outlet 1122 and the indoor air inlet 1121 can also be arranged at other suitable positions of the housing 110, which will not be elaborated here.
[0060] It should be noted that "indoor" is defined as the target area that needs to use the air conditioner 10 for temperature adjustment. Exemplarily, "indoor" can be a bedroom, a living room, or a kitchen in a residence, can be various workshops in a factory, can be various office areas in an office building, etc., and can also be the interior space of a car or a motorhome. Correspondingly, "outdoor" is defined as other areas relatively isolated from the target area. For example, when "indoor" is a room in a residence, "outdoor" can be the environmental area outside the entire residence; when "indoor" is the interior space of a car, "outdoor" can be the space outside the car.
[0061] To facilitate guiding the air flow inside the housing 110, refer to Figures 2-4 andFigure 7 In some embodiments, an air duct housing 120 is disposed within the outer housing 110. A first air duct 121 is defined inside the air duct housing 120. The first air duct 121 is configured to guide the air flow that enters the outer housing 110 through the indoor air inlet 1121 and is discharged from the outer housing 110 through the indoor air outlet 1122. The air duct housing 120 is provided with a first port 1221 and a second port 1233 that communicate with the first air duct 121. The first port 1221 communicates with the indoor air inlet 1121 of the outer housing 110, and the second port 1233 communicates with the indoor air outlet 1122 of the outer housing 110. After the indoor air enters the outer housing 110 through the indoor air inlet 1121, it enters the first air duct 121 through the first port 1221. The air in the first air duct 121 is discharged from the first air duct 121 through the second port 1233 and then is discharged to the indoor through the indoor air outlet 1122.
[0062] The first heat exchanger 200 is disposed within the outer housing 110, and the first heat exchanger 200 is configured to perform heat exchange on the air flow that is introduced into the first air duct 121 through the indoor air inlet 1121. Depending on the operating mode of the air conditioner 10, the first heat exchanger 200 can heat or cool the air flow in the first air duct 121. The relative positional relationship between the first heat exchanger 200 and the air duct housing 120 is determined according to actual needs, as long as the air flow discharged from the first air duct 121 is the air flow after heat exchange with the first heat exchanger 200. In some embodiments, the first heat exchanger 200 can be located outside the air duct housing 120, and the first heat exchanger 200 is located between the first port 1221 and the indoor air inlet 1121. At this time, the air flow that enters the outer housing 110 through the indoor air inlet 1121 flows through the first heat exchanger 200 and then enters the first air duct 121 through the first port 1221. In some other embodiments, the first heat exchanger 200 can be located outside the air duct housing 120, and the air duct housing 120 is divided into two independent air guide housings. The first heat exchanger 200 is located between the two air guide housings. One of the air guide housings is provided with the first port 1221, and the other air guide housing is provided with the second port 1233. The air flow that enters the outer housing 110 through the indoor air inlet 1121 enters one of the air guide housings through the first port 1221, is discharged and then exchanges heat with the first heat exchanger 200. The air flow after heat exchange with the first heat exchanger 200 enters the other air guide housing and is discharged to the indoor air outlet 1122 through the second port 1233. Refer to Figures 2-4 , and Figure 7, in some embodiments, the air duct housing 120 includes a first housing section 122 and a second housing section 123. The first housing section 122 defines a first channel 1222 which communicates with the indoor air inlet 1121, and the second housing section 123 defines a second channel 1234 which communicates with the indoor air outlet 1122. Specifically, the first heat exchanger 200 is completely located within the air duct housing 120 and is positioned between the first channel 1222 and the second channel 1234. This solution can improve the heat exchange efficiency of the first heat exchanger 200, such that the air flow exchanging heat with the first heat exchanger 200 is not easily escaped into the space between the air duct housing 120 and the outer housing 110.
[0063] The electronic control box 400 is used for power distribution, operation control, safety protection, etc. of other various electrically charged components within the air conditioner 10. The electronic control box 400 is disposed within the outer housing 110 and outside the air duct housing 120. The electronic control box 400 includes a box body 410 and electronic devices 420 disposed within the box body 410. The electronic devices 420 include a circuit main board and other electronic components electrically connected to the circuit main board. Refer to Figures 2-4 , and Figure 7 , the box body 410 defines a second air duct 411. The box body 410 is provided with a first heat dissipation air outlet 412 communicating with the second air duct 411. The air outside the box body 410 can enter the second air duct 411 within the box body 410 through the first heat dissipation air outlet 412. The gas entering the second air duct 411 can exchange heat with the electronic devices 420 within the housing, thereby dissipating heat from the electronic devices 420.
[0064] In this embodiment, the air duct housing 120 is provided with a first air guiding opening 1231 communicating with the first air duct 121, and the first heat dissipation air outlet 412 communicates with the first air guiding opening 1231. On the one hand, the air in the first air duct 121 can communicate with the second air duct 411 through the first air guiding opening 1231 and the first heat dissipation air outlet 412, so that the electronic control box 400 can dissipate heat by using the air flow in the air duct housing 120. Compared with the related art solution of setting an additional air supply component 500 to dissipate heat from the electronic control box 400, in this solution, there is no need to set a dedicated air supply component 500 for the electronic control box 400, reducing the number of parts and lowering the cost while the electronic control box 400 can achieve good heat dissipation. On the other hand, in this solution, the electronic control box 400 is not directly disposed in the air duct housing 120, but the air flow is led out from the first air duct 121 through the first air guiding opening 1231 to dissipate heat from the electronic control box 400 located outside the air duct housing 120. Compared with the solution of directly disposing the electronic control box 400 in the first air duct 121 of the air duct housing 120, in this solution, the electronic control box 400 has less obstruction to the air flow in the first air duct 121, the air flow in the first air duct 121 is more smooth, and the air outlet efficiency of the air conditioner 10 is higher. And since the electronic control box 400 does not disrupt the flow state of the air flow in the first air duct 121, the consistency of the air flow led out from the indoor air outlet 1122 is better, which is more conducive to the fine control of the air flow led out from the indoor air outlet 1122. On the third hand, the box body 410 of the electronic control box 400 defines the second air duct 411, and the air flow in the first air duct 121 can enter the second air duct 411 (i.e., enter the interior of the electronic control box 400) through the first air guiding opening 1231, and the heat dissipation effect is better than that of the structure in which the air flow from the first air guiding opening 1231 is led out from the first air guiding opening 1231 and guided to the outer wall of the electronic control box 400. On the fourth hand, since the electronic control box 400 is disposed outside the air duct housing 120, compared with the solution of disposing the electronic control box 400 in the air duct housing 120, since the wire does not need to pass through the air duct housing 120, it is more conducive to the wiring of the electronic control box 400.
[0065] In some embodiments, the electronic control box 400 may have only one air outlet communicating with the outside of the box body 410, which is the first heat dissipation air outlet 412. At this time, the air in the second air duct 411 and the air in the first air duct 121 achieve heat conduction to dissipate heat from the electronic control box 400. See Figures 2-7In some embodiments, the box body 410 is further provided with a second heat dissipation vent 413 connected to the second air duct 411. At this time, the first heat dissipation vent 412 and the second heat dissipation vent 413 jointly realize the air circulation in the second air duct 411, so that the heat dissipation effect of the electric control box 400 is better. In some embodiments, the second heat dissipation vent 413 can be connected to a low-pressure area (lower air pressure than the position of the first air guide 1231), so that the first heat dissipation vent 412 is used for the air intake of the second air duct 411, and the second heat dissipation vent 413 is used for the air outlet of the second air duct 411. In other embodiments, the second heat dissipation vent 413 can be connected to a high-pressure area (higher air pressure than the position of the first air guide 1231), so that the first heat dissipation vent 412 can be used for the air outlet of the second air duct 411, and the second heat dissipation vent 413 can be used for the air intake of the second air duct 411. Since the second heat dissipation vent 413 is provided, the heat in the second air duct 411 can be quickly discharged, thereby improving the heat exchange efficiency of the electric control box 400. For ease of description, the following example is used to illustrate that the first heat dissipation vent 412 is used for air intake and the second heat dissipation vent 413 is used for air discharge.
[0066] See also Figure 7 In some embodiments, the space in the housing 110 other than the first air duct 121 is the internal chamber 116, and the second heat dissipation vent 413 is connected to the internal chamber 116. At this time, the air in the first air duct 121 can be guided to the internal chamber 116 through the second air duct 411 and finally guided out of the housing 110 through the opening of the housing 110. In this solution, on the one hand, the air in the second channel 1234 can circulate, and the heat dissipation effect of the electric control box 400 is better; on the other hand, the second heat dissipation vent 413 can be connected to any area of the internal chamber 116 in the housing 110 other than the first air duct 121. When installing the electric control box 400, there is no need to pay attention to the position and direction of the second heat dissipation vent 413, and the position arrangement of the electric control box 400 is more flexible.
[0067] See also Figure 8 In some embodiments, the housing 110 is provided with a through hole 115, which may be an outdoor air inlet 1111 of the housing 110, an outdoor air outlet 1131 of the housing 110, or other openings of the housing 110. The outer wall of the plate body provided with the second heat dissipation vent 413 of the box body 410 abuts against the inner wall of the plate body provided with the through hole 115 of the housing 110, and the second heat dissipation vent 413 is connected to the through hole 115. In this solution, the air in the second channel 1234 is successively discharged to the outside of the housing 110 through the second heat dissipation vent 413 of the box body 410 and the through hole 115 on the housing 110, and the air flow in the second channel 1234 is not easily directed to the internal chamber 116 between the housing 110 and the air duct housing 120, so that the heat of the electric control box 400 can be discharged to the outside of the housing 110 in time, thereby improving the overall heat dissipation effect of the air conditioner 10.
[0068] Referring to Figures 2-6 , in some embodiments, the housing 110 defines a third air duct 117, and the housing 110 is provided with an outdoor air inlet 1111 and an outdoor air outlet 1131 that are respectively communicated with the third air duct 117. Outdoor air enters the third air duct 117 inside the housing 110 through the outdoor air inlet 1111, and the air in the third air duct 117 is led out to the outside through the outdoor air outlet 1131. Specifically, the second heat exchanger 300 can be arranged in the third air duct 117, and the second heat exchanger 300 is used for heat exchange treatment of the air flow flowing from the outdoor air inlet 1111 to the outdoor air outlet 1131. In this embodiment, the second heat dissipation outlet 413 is communicated with the third air duct 117, so that the second air duct 411 is communicated with the third air duct 117, and the air flow in the second air duct 411 can be guided to the third air duct 117 and then led out to the outside through the outdoor air outlet 1131. In this solution, on the one hand, the hot air flow in the second air duct 411 can be led out to the outside. Compared with the solution in which the hot air flow in the second air duct 411 is introduced into the room, the air conditioner 10 has a higher heat exchange efficiency for the indoor air; on the other hand, since the air flow in the third air duct 117 flows towards the outdoor air outlet 1131, a relatively low-pressure area is formed in the third air duct 117, so a certain suction force is generated on the air in the second air duct 411, and thus the air flow in the second air duct 411 is more easily guided into the third air duct 117, improving the air flow circulation efficiency in the second air duct 411.
[0069] In the above embodiments, the third air duct 117 of the air conditioner 10 is for outdoor air intake and outdoor air outlet. In other embodiments, the third air duct 117 can also be for indoor air intake and outdoor air outlet. Specifically, in some embodiments, the housing 110 defines a third air duct 117, the housing 110 is provided with an indoor air inlet 1121 and an outdoor air outlet 1131 that are respectively communicated with the third air duct 117, the air conditioner 10 further includes a second heat exchanger 300 connected to the first heat exchanger 200, the second heat exchanger 300 is used for heat exchange treatment of the air flow flowing from the indoor air inlet 1121 to the outdoor air outlet 1131, and the second heat dissipation outlet 413 is communicated with the third air duct 117, so that the air flow in the second air duct 411 can be led out to the outside through the third air duct 117. In this solution, in the cooling mode of the air conditioner 10, the indoor air temperature is lower. Therefore, after the second air duct 411 is communicated with the third air duct 117, the cooling effect of the electronic control box 400 is better.
[0070] Referring to Figures 2-6, in some embodiments, the electronic control box 400 has a second air duct 411, and the second air duct 411 communicates with a first heat dissipation air outlet 412 and two second heat dissipation air outlets 413. The first heat dissipation air outlet 412 communicates with the first air guiding opening 1231. One of the second heat dissipation air outlets 413 communicates with the through hole 115 on the side plate of the housing 110, and the other second heat dissipation air outlet 413 communicates with the third air duct 117. The air flow entering the second air duct 411 from the first heat dissipation air outlet 412 is divided into two beams. One beam is led out of the housing 110 through the through hole 115 on the housing 110, and the other beam is guided to the third air duct 117 and finally led out to the outside through the outdoor air outlet 1131. In this solution, the air in the first air duct 121 has multiple leading paths, the air flow circulation efficiency is higher, and at the same time, the circulation area of the first air duct 121 is larger, and the heat dissipation effect is better. In other embodiments, the box body 410 of the electronic control box 400 may have multiple second air ducts 411, and each second air duct 411 communicates with a first heat dissipation air outlet 412 and a second heat dissipation air outlet 413 respectively. Each first heat dissipation air outlet 412 communicates with the first air duct 121 respectively. Each of the second heat dissipation air outlets 413 may communicate with any one of the internal cavity 116 between the housing 110 and the air duct housing 120, the through hole 115 on the housing 110, or the third air duct 117 in the housing 110.
[0071] When the box body 410 has a first heat dissipation air outlet 412 and a second heat dissipation air outlet 413, the first heat dissipation air outlet 412 and the second heat dissipation air outlet 413 may be respectively arranged on two different side plates of the box body 410, so as to increase the circulation area of the second air duct 411 and improve the heat dissipation effect. Further, the first heat dissipation air outlet 412 and the second heat dissipation air outlet 413 may be respectively located on two opposite side plates of the box body 410. For example, the first heat dissipation air outlet 412 is located on the side plate on one side of the box body 410 in the horizontal direction, and the second heat dissipation air outlet 413 is located on the side plate on the other side of the box body 410 in the horizontal direction. When the box body 410 has multiple first heat dissipation air outlets 412 or multiple second heat dissipation air outlets 413, each of the first heat dissipation air outlets 412 and each of the second heat dissipation air outlets 413 may be respectively located on different side plates of the box body 410. See Figures 2-6 , in some embodiments, the box body 410 has a first heat dissipation air outlet 412 and two second heat dissipation air outlets 413. The first heat dissipation air outlet 412 and the two second heat dissipation air outlets 413 are correspondingly arranged on three side plates of the box body 410. Specifically, one of the second heat dissipation air outlets 413 is located on the side plate opposite to the first heat dissipation air outlet 412, and the other second heat dissipation air outlet 413 is located on the side plate beside the first heat dissipation air outlet 412.
[0072] See Figure 10, in some embodiments, the air duct housing 120 is further provided with a second air guide opening 1232. Along the air flow direction in the first air duct 121, the second air guide opening 1232 is located downstream of the first air guide opening 1231 (that is, the air in the first air duct 121 first flows through the first air guide opening 1231 and then through the second air guide opening 1232), and the second air guide opening 1232 communicates with the second heat dissipation air outlet 413. In this solution, both the first heat dissipation air outlet 412 and the second heat dissipation air outlet 413 of the second air duct 411 communicate with the first air duct 121. The air in the first air duct 121 upstream of the first air guide opening 1231 enters the second air duct 411 through the first air guide opening 1231 and then is guided back to the first air duct 121 through the second air guide opening 1232. Since the second air duct 411 only communicates with the first air duct 121, the box body 410 of the electronic control box 400 can be fixed only to the air duct housing 120, which is convenient for the modular assembly of the electronic control box 400 and the air duct housing 120. Moreover, the air entering the first air duct 121 from the indoor air inlet 1121 can be completely discharged from the indoor air outlet 1122, making it easier to accurately control the air volume of the indoor air outlet 1122.
[0073] See Figures 2-6 , in some embodiments, the electronic control box 400 further includes a heat dissipation part 430. One end of the heat dissipation part 430 is located inside the box body 410 and is attached to the electronic device 420, and the other end extends outside the box body 410. The part of the heat dissipation part 430 attached to the electronic device 420 is used to obtain the heat of the electronic device 420, and the part of the heat dissipation part 430 extending outside the box body 410 is used to exchange heat with the air outside the box body 410, so as to realize the heat dissipation of the electronic device 420. Specifically, the part of the heat dissipation part 430 extending outside the box body 410 can be provided with a plurality of heat dissipation fins, so as to increase the contact area with the air and improve the heat dissipation effect. In this embodiment, the part of the heat dissipation part 430 located outside the box body 410 is arranged opposite to the second heat dissipation air outlet 413 at an interval, so that the air flow discharged from the second heat dissipation air outlet 413 can flow through the part of the heat dissipation part 430 extending outside the box body 410, thereby improving the heat exchange efficiency between the heat dissipation part 430 and the air, and thus improving the heat dissipation effect on the electronic device 420. To further improve the heat dissipation effect on the electronic device 420, in this embodiment, the second heat dissipation air outlet 413 communicates with the third air duct 117, and the part of the heat dissipation part 430 extending outside the box body 410 is located in the third air duct 117. With this setting, the air flow discharged from the second heat dissipation air outlet 413 can be mixed with the air flow introduced into the housing 110 from the outdoor air inlet 1111 to dissipate heat from the heat dissipation part 430, further improving the heat dissipation effect of the heat dissipation part 430.
[0074] The first air guide 1231 and the first heat dissipation vent 412 can be directly connected or indirectly connected. When the first air guide 1231 and the first heat dissipation vent 412 are directly connected, the port of the first heat dissipation vent 412 of the box body 410 directly abuts against the port of the first air guide 1231, and the airflow guided by the first air guide 1231 immediately passes through the first heat dissipation vent 412. When the first air guide 1231 and the first heat dissipation vent 412 are indirectly connected, see Figures 2-4 In some embodiments, the outer wall of the air duct housing 120 is provided with an annular protrusion 124, the box body 410 is connected to one end of the annular protrusion 124 away from the first air duct 121, the port at one end of the annular protrusion 124 is connected to the first air guide port 1231, and the port at the other end is connected to the first heat dissipation air outlet 412. In other words, the first air guide port 1231 is indirectly connected to the first heat dissipation air outlet 412 through the annular protrusion 124, and the airflow guided out of the first air guide port 1231 flows through the inside of the annular protrusion 124 and then guides to the first heat dissipation air outlet 412. In this solution, by providing the annular protrusion 124, the position setting of the first air guide port 1231 can be made more flexible. When the first air guide port 1231 is provided at the curved wall plate of the air duct housing 120, the electric control box 400 can also be conveniently connected to the first air guide port 1231.
[0075] When the first air guide port 1231 is indirectly connected to the first heat dissipation air outlet 412, in other embodiments, the housing assembly 100 further includes a conducting tube 125, one end of the conducting tube 125 is connected to the air duct shell 120, and the other end is connected to the box body 410, and the two ends of the inner cavity of the conducting tube 125 are respectively connected to the first heat dissipation air outlet 412 and the first air guide port 1231. In this solution, the conducting tube 125 is respectively connected to the air duct shell 120 and the box body 410, and the length and hardness of the conducting tube 125 can be determined according to actual needs, so that the position arrangement of the electric control box 400 is more flexible. When the position of the electric control box 400 needs to be adjusted, the position of the electric control box 400 can be matched by replacing the conducting tube 125 of different lengths and shapes. Furthermore, when the electric control box 400 is far away from the air duct shell 120 , the conducting tube 125 can also be set as a hose, so as to avoid other components between the electric control box 400 and the air duct shell 120 , thereby facilitating the connection between the first air guide port 1231 and the first heat dissipation air outlet 412 .
[0076] See also Figures 2-4 ,as well as Figure 7, in some embodiments, the air duct housing 120 includes a first housing section 122 and a second housing section 123. The first housing section 122 defines a first channel 1222, and the second housing section 123 defines a second channel 1234. The first channel 1222 communicates with the indoor air inlet 1121, and the second channel 1234 communicates with the indoor air outlet 1122. The first heat exchanger 200 is at least partially located between the first channel 1222 and the second channel 1234. The first air guide opening 1231 can be provided on the first housing section 122 or on the second housing section 123. To improve the heat dissipation efficiency of the electronic control box 400, the first air guide opening 1231 is provided on the second housing section 123. This solution makes the temperature of the air flow in the second housing section 123 lower when the first heat exchanger 200 is in the cooling mode, which is more conducive to dissipating heat from the electronic control box 400.
[0077] To prevent the high-temperature air in the second air duct 411 from flowing into the first air duct 121, it is necessary to make the position of the first air outlet in the high-pressure area, so that the air flow at the position of the first air outlet can flow into the second air duct 411. In view of this, see Figures 2-4 , in some embodiments, the second channel 1234 includes a driving cavity 1235 and a wind guiding cavity 1236. The driving cavity 1235 is used to arrange the first air supply part 510. The first air supply part 510 may specifically include a centrifugal fan 511. The centrifugal fan 511 rotates in the driving cavity 1235 to cause air flow in the driving cavity 1235. One end of the wind guiding cavity 1236 communicates with the driving cavity 1235, and the other end communicates with the indoor air outlet 1122. The air flow generated in the driving cavity 1235 is led out to the indoor through the wind guiding cavity 1236. The centrifugal fan 511 is configured to drive the air inside itself to diverge towards its outer periphery. The first channel 1222 is communicated with the inside of the centrifugal fan 511, so that the gas in the first channel 1222 is sucked into the driving cavity 1235. The first air guide opening 1231 communicates with the driving cavity 1235 and is located on the outer peripheral side of the centrifugal fan 511. Since the outer peripheral side of the centrifugal fan 511 is in the high-pressure area, the air flow at the first air guide opening 1231 is driven to flow into the second air duct 411, thereby preventing the high-temperature air flow in the second air duct 411 from flowing into the first air duct, and improving the heat exchange efficiency of the air conditioner 10 for indoor air.
[0078] See Figures 7-8 , in some embodiments, the second air duct 411 can be the inner cavity of the box body 410, that is, the space jointly enclosed by the upper cover plate and the lower cover plate of the housing is the second air duct 411. At this time, the electronic device 420 is located in the second air duct 411, and the air flow in the second air duct 411 directly contacts all the components in the box body 410, so as to improve the heat exchange efficiency. See Figure 9, in some other embodiments, the housing 110 further defines an annular cavity 414 separated from the heat dissipation air duct. The annular cavity 414 is arranged around the second air duct 411, and the electronic device 420 is arranged in the annular cavity 414. In this solution, the second air duct 411 is not the inner cavity of the box body 410, while the annular cavity 414 is the inner cavity of the box body 410. The air flow in the second air duct 411 exchanges heat with the inner side wall of the box body 410 and then indirectly exchanges heat with the electronic device in the annular cavity 414. Since the electronic device 420 does not directly contact the air flow in the second air duct 411, it can avoid the dust and particles doped in the air flow from contacting the electronic device 420, reduce the probability of damage to the electronic device 420, and improve the service life of the electric control box 400.
[0079] An embodiment of the second aspect of the present invention further provides a vehicle. The type of the vehicle can be a sedan, an SUV, an MPV, a truck or a motor home, etc. The vehicle includes a vehicle body and the air conditioner 10 in any of the above embodiments. The air conditioner 10 is arranged in the vehicle body, and the indoor air inlet 1121 and the indoor air outlet 1122 of the air conditioner 10 are both communicated with the interior space of the vehicle body to adjust the temperature of the air in the interior space of the vehicle. The outdoor air outlet 1131 and the outdoor air inlet 1111 of the air conditioner 10 are both communicated with the external space of the vehicle to export the gas heat-exchanged with the second heat exchanger 300 to the outside of the vehicle.
[0080] The specific arrangement position of the air conditioner 10 in the vehicle body depends on the type of the vehicle. For example, when the vehicle is a sedan, the air conditioner 10 can be arranged at the front of the vehicle, and the indoor air outlet 1122 and the indoor air inlet 1121 of the air conditioner 10 are both arranged forward to intake air from the back to the front and exhaust air from the front to the back. When the vehicle is a motor home, the air conditioner 10 can be installed in the top space of the vehicle, and the indoor air outlet 1122 and the indoor air inlet 1121 of the air conditioner 10 are both arranged downward to intake air from the bottom to the top and exhaust air from the top to the bottom.
