DETAILED DESCRIPTION

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0038] In the present disclosure, unless otherwise stated, directional words such as "upper", "lower", "top", and "bottom" are generally defined when the air conditioner outdoor unit provided by the present disclosure is normally installed. Figure 4 In the drawing directions shown in , "inside" and "outside" refer to the inside and outside of the corresponding component outline. In addition, the terms "first", "second", etc. used in this disclosure are to distinguish one element from another element and do not have order and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0039] In the relevant embodiment of the present disclosure, a radiator 4 is installed on the electric control box 3 to dissipate heat from the components, and the fan 6 is used to suck air so that the cooling air generated by the condenser 2 flows through the radiator 4. At the same time, in order to make the cooling air flowing through the radiator 4 more concentrated, an air guide structure is provided below the radiator 4 to improve the heat exchange efficiency of the radiator 4. In this embodiment, the arrangement direction of the multiple fins 41 of the radiator 4 is arranged perpendicular to the flow direction of the cooling air, that is, the cooling air directly flows into the gaps between adjacent fins 41, and the direction of the fins 41 is consistent with the flow direction of the cooling air. Under this arrangement, the air guide structure can directly wrap the radiator 4, and can only achieve the heat dissipation of the components directly connected to the radiator 4, and cannot take into account the heat dissipation inside the electric control box 3.

[0040] To solve the above problems, Figures 1 to 9As shown, the present disclosure provides an air conditioner outdoor unit, which includes a casing 1 and a condenser 2 and a compressor (not shown in the figure) installed in the casing 1. A baffle 7 is vertically arranged between the condenser 2 and the compressor, and an electric control box 3 is installed on the upper part of the baffle 7. Among them, the electric control box 3 has a heat dissipation duct 31 connected to the cavity where the compressor is located. The heat dissipation duct 31 can increase the air flow in the cavity where the compressor is located. Under the action of the fan 6, the air flow flows from the outlet of the heat dissipation duct 31 through the radiator 4 to dissipate heat inside. A plurality of high-power components are installed on the electric control box 3. In order to dissipate heat for the components, a radiator 4 is installed on the electric control box 3, and a collector cap 5 is arranged below the radiator 4. The collector cap 5 is used to guide the air flow of the condenser 2 to the radiator 4, so as to improve the heat dissipation effect of the radiator 4 and achieve the purpose of reducing the temperature of the components. The radiator 4 includes a plurality of fins 41 arranged at intervals. In this embodiment, the arrangement direction of the plurality of fins 41 is perpendicular to the flow direction of the airflow discharged from the heat dissipation duct 31, and the arrangement direction of the plurality of fins 41 is the same as the flow direction of the airflow of the condenser 2. It should be noted here that the airflow flowing out of the heat dissipation duct 31 is a hot airflow, which directly flows into the radiator 4 for heat dissipation, and the airflow of the condenser 2 is a cold airflow, which can cool the radiator 4 and improve the heat dissipation effect of the radiator 4. In addition, the baffle 7 can be constructed as an arc-shaped plate, which is used to wrap the compressor inside and separate it from the condenser 2. The electric control box 3 is installed on the top of the baffle 7, and the heat dissipation duct 31 extends to the baffle 7 and is connected to the cavity where the compressor is located.

[0041] Through the above technical scheme, in the air-conditioning outdoor unit provided by the present invention, the heat dissipation duct 31 can increase the air flow in the cavity where the compressor is located, and the exhausted air flow directly flows into the gap between adjacent fins 41 for heat dissipation, thereby ensuring the heat dissipation inside the electric control box 3; at the same time, under the action of the collecting cap 5, the air flow of the condenser 2 will also be guided to the radiator 4, which can improve the heat dissipation effect of the radiator 4, while taking into account the internal heat dissipation of the electric control box 3 and the heat dissipation of the heating elements on the electric control box 3, thereby improving the overall heat dissipation effect, avoiding damage to the electric control box 3 and components due to excessive temperature, and ensuring the normal operation of the whole machine.

[0042] In this disclosure, Figure 7As shown, the radiator 4 includes a top plate 40 for connecting to the electric control box 3, the upper edges of a plurality of fins 41 are fixed on the top plate 40, the lower edges of the fins 41 are arranged at intervals with the collecting cap 5 to form a collecting chamber 400, wherein the airflow discharged from the heat dissipation duct 31 directly enters the gap between adjacent fins 41 for heat dissipation; under the action of the fan 6, the airflow enters the fan cavity through the condenser 2, and is then discharged to the outside of the air conditioner outdoor unit by the fan blades of the fan 6, and a part of the airflow passing through the condenser 2 first enters the collecting chamber 400 under the action of the collecting cap 5, and flows upward into the gap between adjacent fins 41, and the overall path is L-shaped, which cools the radiator 4, accelerates the flow of airflow inside the radiator 4, increases the contact area between the airflow and the radiator 4, improves the heat exchange effect of the radiator 4, and reduces the temperature of components. The air conditioner outdoor unit can not only ensure the heat dissipation inside the electric control box 3, but also gather more cold airflow to dissipate the heat of the radiator 4, thereby ensuring the heat dissipation of the heating elements directly connected to the radiator 4, ensuring the safe use of components, and thus ensuring the comfort of the whole machine and the usability of the user.

[0043] The current collecting cap 5 may be of any suitable structure. In an exemplary embodiment of the present disclosure, Figure 5 and Figure 6 As shown, the collector cap 5 includes a bottom plate 51 arranged at intervals below the radiator 4, and a first side baffle 52 and a second side baffle 53 connected to the bottom plate 51, wherein the first side baffle 52 is arranged opposite to the air outlet 30 of the heat dissipation air duct 31 and is arranged on both sides of the arrangement direction of the multiple fins 41; the second side baffle 53 is arranged adjacent to the first side baffle 52, and the second side baffle 53 is arranged opposite to the condenser 2. Figure 7 As shown, the bottom plate 51 and the lower ends of the fins 41 are arranged at intervals to form a collecting chamber 400. A first side baffle 52 is provided on the side away from the air outlet 30 in the direction of the airflow discharged from the heat dissipation duct 31, and a second side baffle 53 is provided on the side away from the condenser 2 in the direction of the airflow of the condenser 2, which can prevent the airflow from flowing out from the other end of the collecting cap 5, ensure that the airflow in the collecting chamber 400 flows upward, prolong the time the airflow stays at the radiator 4, and improve the heat exchange effect. In other embodiments, a third side baffle arranged opposite to the first side baffle 52 can be added, and an opening for avoiding the air outlet 30 can be opened on the third side baffle. The third side baffle is used to be installed on the side wall of the electric control box 3. Any deformation that can achieve the above effect belongs to the protection scope of the present disclosure.

[0044] In this disclosure, Figure 6As shown, the surface of the collecting cap 5 opposite to the first side baffle 52 forms a first opening 501, one side of the first opening 501 abuts against the side wall of the electric control box 3, and the surface of the collecting cap 5 opposite to the second side baffle 53 forms a second opening 502, and the second opening 502 is configured as the inlet of the airflow of the condenser 2. Under the premise of collecting the airflow, the structure of the collecting cap 5 can be ensured to be the simplest, in line with the design principle of lightweight. In this embodiment, the bottom plate 51, the first side baffle 52 and the second side baffle 53 are all rectangular plates. In other embodiments, their shapes and sizes can be designed according to needs and installation space requirements.

[0045] There are many ways to install the current collecting cap 5 on the side wall of the electric control box 3, such as snap-on, welding, fastener connection, etc. Figure 5 As shown, the side of the first opening 501 for fitting with the electric control box 3 is provided with a plurality of spaced connection ears 55, and the connection ears 55 are provided with fastening holes. The collecting cap 5 is detachably mounted on the side wall of the electric control box 3 by fasteners passing through the fastening holes. The connection ears 55 are respectively arranged vertically with the bottom plate 51 and the second side baffle plate 53, and can fit with the side wall of the electric control box 3 to stably fix the collecting cap 5 on the side wall of the electric control box 3.

[0046] like Figures 5 to 8 As shown, the edge of the second opening 502 has an outward-expanding flange 54, and the second opening 502 is designed as an outward-expanding structure, which can ensure that more airflow from the condenser 2 enters the collecting cap 5 to dissipate heat from the radiator 4. In this embodiment, the angle between the flange 54 and the radiator body is α, wherein 0°≤α≤75°, preferably, 0°≤α≤70°, and the angle α can be designed as needed.

[0047] like Figure 7 As shown, a first interval d is maintained between the lower end of the fin 41 and the bottom plate 51, wherein 5mm≤d≤85mm, preferably, 10mm≤d≤80mm. The size of the first interval d determines the height of the collecting chamber 400. The larger the size of the first interval d, the more airflow of the condenser 2 can be collected. The size of the first interval d can be designed according to needs. Figure 8As shown, the first side baffle 52 and the second side baffle 53 need to maintain a certain distance from the side wall surface of the fin 41 of the radiator 4, and the first side baffle 52 maintains a second interval D with the side wall of the plurality of fins 41, wherein 0.5mm≤D≤11mm, preferably, 1mm≤D≤10mm. The second side baffle 53 maintains a third interval h with the fin 41 closest to the second side baffle 53, wherein 0.5mm≤h≤11mm, preferably, 1mm≤h≤10mm, to avoid interference between the collector cap 5 and the radiator 4 during installation, so that the radiator 4 can be completely wrapped in the inner cavity of the collector cap 5. The above parameters can be designed specifically according to the size of the fin 41 of the radiator 4.

[0048] In order to ensure that the airflow flowing out of the air outlet 30 of the heat dissipation air duct 31 is discharged in time after passing through the radiator 4 and will not be blocked by the second side baffle 53, in this embodiment, Fig. 9 As shown, the height of the top edge of the air outlet 30 is A, and the height of the second side baffle 53 is L, wherein A>L, so that the hot air flow of the heat dissipation duct 31 can be discharged in time.

[0049] In the present disclosure, the structure of the electric control box 3 is designed accordingly, such as Figure 3 and Figure 4 As shown, the electric control box 3 includes a side cavity 300 for forming a heat dissipation duct 31 and a top wall 33 for carrying components. The top wall 33 extends beyond the side cavity 300. The heat sink 4 and the collector cap 5 are installed below the top wall 33 and are located in the same horizontal direction as the side cavity 300. The air outlet 30 is opened on the side wall of the side cavity 300, which does not affect the installation of multiple components on the electric control box 3. At the same time, the existing space of the electric control box 3 is utilized to install the heat sink 4 and the collector cap 5 on the electric control box 3. After the collector cap 5 is installed on the radiator 4, more airflow can enter the collector cap 5 and then fully contact with the radiator 4, thereby improving the heat dissipation effect of the radiator 4 and achieving the purpose of reducing the temperature rise of the components.

[0050] According to a second aspect of the present disclosure, an air conditioner is also provided, comprising the air conditioner outdoor unit described above.
