[0035] The present application proposes an air conditioner 100. The air conditioner 100 can be a split-type air conditioner 100 that is easy for users to install personally. It uses a flexible refrigerant pipe to connect the indoor heat exchanger of the air conditioner indoor unit and the outdoor heat exchanger of the air conditioner outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by themselves, they only need to fix the air conditioner indoor unit and the air conditioner outdoor unit separately, without the need to assemble the refrigerant pipe and add refrigerant, thereby reducing the difficulty of installation and enabling personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner 100 of the present application can also be an ordinary split-type air conditioner 100, or an integrated air conditioner 100.

[0036] In an embodiment of the present application, as shown in Figures 1 to 3, the air conditioner 100 includes a fan assembly 110, a heat exchanger 120, a mounting member 130 and an electrical control box 140. The heat exchanger 120 is spaced apart on the air inlet side 111 of the fan assembly 110, and the mounting member 130 is located on one side of the heat exchanger 120; the electrical control box 140 is installed on the mounting member 130, and the outer wall of the electrical control box 140 and the mounting member 130 form a heat dissipation cavity 141, in which a radiator 150 is provided. The air inlet 142 of the heat dissipation cavity 141 is provided on the side of the heat exchanger 120 away from the fan assembly 110, and the air outlet 143 of the heat dissipation cavity 141 is provided on the side of the heat exchanger 120 facing the fan assembly 110 to connect to the air inlet side 111.

[0037] Specifically, the air conditioner 100 includes a housing and a main air inlet and main air outlet formed on the housing surface. A fan assembly 110, a heat exchanger 120, and an electrical control box 140 are all disposed within the housing. The heat exchanger 120 is spaced apart from the air inlet side 111 of the fan assembly 110, that is, located at the main air inlet. A mounting member 130 is provided on one side of the heat exchanger 120. This mounting member 130 is used to secure the electrical control box 140, allowing it to be fixedly mounted on the side where the heat exchanger 120 is located. The electrical control box 140 can be located on the side, bottom, or top surface of the heat exchanger 120. Designers can adjust the position of the electrical control box 140 based on the layout of the fan assembly 110, heat exchanger 120, compressor (expansion valve), and other components within the air conditioner 100. The outer wall of the electrical control box 140 and the mounting member 130 form a heat dissipation cavity 141. A radiator 150 is located within the heat dissipation cavity 141, thereby accelerating air flow and increasing the heat dissipation area on the surface of the electrical control box 140, quickly removing heat generated by the electrical control box 140 and helping to dissipate heat from the electrical control box 140. The heat dissipation cavity 141 extends along the thickness of the heat exchanger 120. The air inlet 142 of the heat dissipation cavity 141 is located on the side of the heat exchanger 120 facing away from the fan assembly 110, directly connecting to the main air inlet. The air outlet 143 of the heat dissipation cavity 141 is located on the side of the heat exchanger 120 facing the fan assembly 110, connecting to the air inlet side 111. As a result, the air inlet 142 and air outlet 143 of the heat dissipation cavity 141 are arranged astride the heat exchanger 120, so that air flowing through the heat dissipation cavity 141 does not undergo heat exchange in the heat exchanger 120 and is natural wind. If the gas entering the heat dissipation chamber 141 is heat-exchanged gas, such as in cooling mode, the air temperature after heat exchange in the heat exchanger 120 is relatively low, and condensation may form upon entering the heat dissipation chamber 141. This condensation accumulates in the heat dissipation chamber 141 and is difficult to drain. It may also enter the interior of the electrical control box 140, where water droplets are likely to fall onto the electrical components of the electrical control box 140, potentially causing malfunctions. In heating mode, the air temperature after heat exchange in the heat exchanger 120 is relatively high, making it difficult to dissipate heat upon entering the heat dissipation chamber 141. Therefore, directly connecting the air inlet 142 of the heat dissipation chamber 141 to the main air inlet minimizes the possibility of heat exchanged by the heat exchanger 120 entering the heat dissipation chamber 141, thereby reducing the possibility of condensation forming within the heat dissipation chamber 141.

[0038] Furthermore, the air outlet 143 of the heat dissipation cavity 141 is located on the side of the heat exchanger 120 facing the fan assembly 110, so as to connect to the air inlet side 111. The air inlet side 111 of the fan assembly 110 forms a negative pressure area. The air outlet 143 directly connects to the air inlet side 111, effectively increasing the velocity of the airflow through the heat dissipation cavity 141. This further accelerates the air flow on the surface of the electrical control box 140, quickly removing the heat generated by the electrical control box 140 and helping the electrical control box 140 dissipate heat. Therefore, the air outlet 143 is located toward the air inlet 142 of the fan assembly 110, thereby further increasing the velocity of the airflow through the heat dissipation cavity 141.

[0039] Furthermore, multiple air inlets 142 are provided, and the multiple air inlets 142 are disposed on the bottom wall and side walls of the heat dissipation cavity 141. Specifically, the multiple air inlets 142 are disposed at one end of the heat dissipation cavity 141 away from the heat exchanger 120 and the fan assembly 110, thereby effectively increasing the amount of air flowing through the heat dissipation cavity 141, thereby further accelerating the flow rate of the air flowing through the heat dissipation cavity 141, and further accelerating the air flow on the surface of the electrical control box 140, quickly removing the heat generated by the electrical control box 140, and helping the electrical control box 140 to dissipate heat. Multiple air inlets 142 are arranged on the bottom wall and side walls of the heat dissipation cavity 141. In order to ensure the heat exchange efficiency of the air conditioner 100, the heat exchanger 120 usually covers the main air inlet. Therefore, the heat dissipation cavity 141 needs to be arranged on the outer peripheral side of the air outlet 143. If the air inlets 142 are only arranged on the side walls of the heat dissipation cavity 141, it may be difficult to ensure the air intake of the heat dissipation cavity 141. Therefore, the side walls of the heat dissipation cavity 141 are also provided with air inlets 142, which not only increases the number of air inlets 142, but also increases the air intake path, thereby ensuring the air flow through the heat dissipation cavity 141.

[0040] In one embodiment, the air inlet 142 and / or the air outlet 143 are provided with a grille structure 144. Specifically, the grille structure 144 can effectively prevent impurities in the air from entering the heat dissipation cavity 141, thereby reducing the possibility of clogging the second heat dissipation channel 162 in the radiator 150 and reducing the possibility of dust in the air entering the interior of the electrical control box 140 through the heat exchange cavity.

[0041] The technical solution of the present application is to arrange the heat exchanger 120 on the air inlet side 111 of the fan assembly 110, and the mounting member 130 is located on one side of the heat exchanger 120; the electric control box 140 is installed on the mounting member 130, and the outer wall of the electric control box 140 and the mounting member 130 form a heat dissipation cavity 141, so that the gas flowing through the heat dissipation cavity 141 can take away the heat on the surface of the electric control box 140, and a radiator 150 is provided in the heat dissipation cavity 141, so as to accelerate the air flow and heat dissipation area on the surface of the electric control box 140, quickly take away the heat generated by the electric control box 140, and help the electric control box 140 to dissipate heat. The air inlet 142 of the heat dissipation chamber 141 is located on the side of the heat exchanger 120 facing away from the fan assembly 110, directly connecting to the main air inlet. The air outlet 143 of the heat dissipation chamber 141 is located on the side of the heat exchanger 120 facing the fan assembly 110, connecting to the air inlet side 111. This arrangement allows the air inlet 142 and air outlet 143 of the heat dissipation chamber 141 to straddle the heat exchanger 120, ensuring that the air flowing through the heat dissipation chamber 141 is naturally winded without undergoing heat exchange in the heat exchanger 120. The direct connection between the air inlet 142 of the heat dissipation chamber 141 and the main air inlet minimizes the possibility of gas heated by the heat exchanger 120 entering the heat dissipation chamber 141, thereby reducing the possibility of condensation forming within the heat dissipation chamber 141. Furthermore, the air outlet 143 of the heat dissipation cavity 141 is directly connected to the air inlet side 111. A negative pressure zone is formed on the air inlet side 111 of the fan assembly 110. The direct connection of the air outlet 143 to the air inlet side 111 effectively accelerates the velocity of the airflow through the heat dissipation cavity 141, thereby further increasing the air flow on the surface of the electrical control box 140, quickly removing the heat generated by the electrical control box 140 and helping the electrical control box 140 dissipate heat. Therefore, the air outlet 143 is disposed toward the air inlet 142 of the fan assembly 110, thereby further accelerating the velocity of the airflow through the heat dissipation cavity 141.

[0042] Referring again to Figures 1 to 3, in one embodiment, the mounting member 130 is disposed on the top of the heat exchanger 120, and the electrical control box 140 is fixed to the side of the mounting member 130 facing away from the heat exchanger 120. Specifically, the electrical control box 140 is disposed on the top of the heat exchanger 120. In this embodiment, the fan assembly 110 includes a volute air duct 112, and the air outlet 143 is disposed on the top surface of the air conditioner 100. Therefore, there is a certain gap between the heat exchanger 120 and the top surface of the housing. The electrical control box 140 is disposed in this gap, which can effectively utilize the space within the housing, thereby effectively reducing the overall volume of the air conditioner 100, thereby reducing the space occupied by the air conditioner 100 and achieving miniaturization of the air conditioner 100. The mounting member 130 is provided on the top of the heat exchanger 120, and the electric control box 140 is fixed to the side of the mounting member 130 facing away from the heat exchanger 120, so that the mounting member 130 has a certain supporting effect on the electric control box 140, thereby realizing the installation of the electric control box 140 and ensuring the installation stability of the electric control box 140.

[0043] Furthermore, the fan assembly 110 includes a volute air duct 112, and the mounting member 130 is integrally formed with the volute air duct 112. Specifically, because the electrical control box 140 is disposed above the heat exchanger 120, the mounting member 130 can be configured as a plate-like structure extending toward the heat exchanger 120. The electrical control box 140 is fixed to the side of the mounting member 130 facing away from the heat exchanger 120. Compared to when the electrical control box 140 is fixed to the side of the mounting member 130 facing the heat exchanger 120, the plate-like structure can also isolate the electrical control box 140 from the heat exchanger 120, thereby ensuring the installation stability of the electrical control box 140. Furthermore, the mounting member 130 is integrally formed with the volute air duct 112, thereby reducing the number of splicing operations between the mounting member 130 and the volute air duct 112 and the number of installation steps, while also ensuring the installation stability of the mounting member 130, and thus the electrical control box 140. Of course, in other embodiments, the mounting member 130 can also be snapped or bonded to the volute air duct 112 .

[0044] Furthermore, a support structure 160 is formed on the side of the fan assembly 110 facing the heat exchanger 120. This support structure 160 abuts against the bottom of the mounting member 130. Specifically, because the mounting member 130 not only has a certain weight itself but also needs to bear the weight of the electrical control box 140, to further enhance the installation stability of the electrical control box 140, a support structure 160 is formed on the side of the fan assembly 110 facing the heat exchanger 120. One end of the support structure 160 abuts against the bottom of the mounting member 130, and the other end abuts against the inner bottom wall of the housing, thereby effectively ensuring the installation stability of the mounting member 130. Furthermore, the support structure 160 can be configured as a plate-like or columnar structure arranged at intervals along the width of the mounting member 130, thereby effectively increasing the support strength of the mounting member 130 and ensuring its installation stability.

[0045] In one embodiment, the mounting member 130 includes a support plate 131 and a mounting plate 132 arranged at an angle, the outer wall of the electrical control box 140, the mounting plate 132 and part of the support plate 131 enclose a heat dissipation cavity 141, the air outlet 143 is provided on the support plate 131, and the air inlet 142 is provided on the support plate 131 and / or the mounting plate 132; and / or the electrical control box 140, the mounting plate 132 and the support plate 131 enclose an air inlet 142. Specifically, the support plate 131 and the mounting plate 132 are arranged at an angle, the support plate 131 and the heat exchanger 120 are arranged relatively parallel, the support structure 160 is supported and abutted against the support plate 131, the mounting plate 132 is provided at one end of the support plate 131, and the mounting plate 132 is spaced relative to the electrical control box 140, so that the outer wall of the electrical control box 140, the mounting plate 132, and a portion of the support plate 131 enclose a heat dissipation cavity 141. The radiator 150 is disposed within the heat dissipation cavity 141, thereby dissipating heat from the side wall of the electrical control box 140 toward the mounting plate 132. The air outlet 143 is provided on the support plate 131, so that the air outlet 131 is disposed toward the air inlet side 111 of the fan assembly 110, thereby reducing the flow path from the heat dissipation cavity 141 to the air inlet side 111 of the fan assembly 110. Multiple air inlets 142 are provided, and are disposed on the support plate 131 and the mounting plate 132. Together with the electrical control box 140, the mounting plate 132, and the support plate 131, the air inlets 142 are formed. Thus, the air inlets 142 are provided on both the sidewalls and the bottom wall of the heat dissipation cavity 141, which not only increases the number of air inlets 142 but also increases the air inlet path, thereby ensuring the air flow through the heat dissipation cavity 141.

[0046] Furthermore, the support plate 131 is provided with support ribs 133, which abut against the electric control box 140, so that the electric control box 140 is spaced apart from the support plate 131. Specifically, to further enhance the heat dissipation effect of the electric control box 140, the support plate 131 is provided with support ribs 133, and multiple support ribs 133 extend along the width direction of the mounting plate 132. The multiple support ribs 133 and the support plate 131 together form a first heat dissipation channel 134. The first heat dissipation channel 134 connects the main air inlet and the air outlet 143, thereby increasing the airflow velocity from the side wall surface of the electric control box 140 toward the support plate 131, thereby further increasing the heat dissipation area of ​​the electric control box 140 and improving the heat dissipation efficiency of the electric control box 140.

[0047] In one embodiment, the mounting member 130 and the electrical control box 140 are engaged via a snap-fit ​​structure; the mounting member 130 is fastened to the heat sink 150 via the electrical control box 140. Specifically, the electrical control box 140 is mounted on the mounting member 130 via both the snap-fit ​​structure and the fasteners, thereby ensuring both stable and convenient installation of the electrical control box 140. The fasteners can be configured as fastening screws or bolts.

[0048] 1 to 5 , in one embodiment, the heat sink 150 includes a plurality of heat dissipating fins 161 spaced apart within a heat dissipating cavity 141. Specifically, the heat dissipating fins 161 have excellent thermal conductivity, thereby quickly dissipating heat from the surface of the electrical control box 140. Furthermore, the plurality of heat dissipating fins 161 are spaced apart within the heat dissipating cavity 141, and second heat dissipating channels 162 are formed between adjacent heat dissipating fins 161, thereby further dissipating heat from the surfaces of the heat dissipating fins 161 and improving the heat dissipation effect of the electrical control box 140.

[0049] Furthermore, a plurality of heat dissipation fins 161 extend from the air inlet 142 toward the air outlet 143. Specifically, the plurality of heat dissipation fins 161 extend from the air inlet 142 toward the air outlet 143, that is, the second heat dissipation channel 162 extends from the air inlet 142 toward the air outlet 143, so that the second heat dissipation channel 162 directly connects the air inlet 142 and the air outlet 143, thereby reducing the possibility of airflow being blocked within the heat dissipation cavity 141, thereby effectively accelerating the air flow within the heat dissipation cavity 141, and further improving the heat dissipation efficiency of the heat dissipation fins 161, thereby improving the heat dissipation effect of the electronic control box 140.

[0050] Furthermore, the surface of the heat dissipation fins 161 is configured as a wavy surface, thereby increasing the effective heat dissipation area of ​​the heat dissipation fins 161 , thereby improving the heat dissipation efficiency of the radiator 150 , and further improving the heat dissipation effect of the electric control box 140 .
