[0034] The present invention 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 injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the air conditioner indoor unit and the air conditioner outdoor unit separately, without assembling the refrigerant pipe and filling the refrigerant, thereby reducing the difficulty of installation and realizing personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner 100 of the present invention can also be an ordinary split-type air conditioner 100, or an integrated air conditioner 100.

[0035] In the embodiment of the present invention, Figures 1 to 3 As shown, the air conditioner 100 includes a fan assembly 110, a heat exchanger 120, a mounting member 130 and an electric 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 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, in which a radiator 150 is arranged, an air inlet 142 of the heat dissipation cavity 141 is arranged on the side of the heat exchanger 120 away from the fan assembly 110, and an air outlet 143 of the heat dissipation cavity 141 is arranged on the side of the heat exchanger 120 facing the fan assembly 110 to connect to the air inlet side 111.

[0036] Specifically, the air conditioner 100 includes a housing and a main air inlet and a main air outlet formed on the surface of the housing. The fan assembly 110, the heat exchanger 120 and the electric control box 140 are all arranged in the housing. The heat exchanger 120 is arranged at an interval on the air inlet side 111 of the fan assembly 110, that is, the heat exchanger 120 is arranged at the main air inlet. A mounting member 130 is provided on one side of the heat exchanger 120, and the mounting member 130 is used to fix the electric control box 140, so that the electric control box 140 is fixedly installed on the side where the heat exchanger 120 is located, and the electric control box 140 can be arranged on the side, bottom or top surface of the heat exchanger 120. The designer can adjust the position of the electric control box 140 according to the arrangement of the fan assembly 110, the heat exchanger 120, the compressor (expansion valve), etc. in the air conditioner 100. The outer wall of the electric control box 140 and the mounting member 130 form a heat dissipation cavity 141, and a radiator 150 is arranged 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 dissipate heat. The heat dissipation cavity 141 extends along the thickness direction of the heat exchanger 120, and the air inlet 142 of the heat dissipation cavity 141 is arranged on the side of the heat exchanger 120 away from the fan assembly 110 to directly connect to the main air inlet, and the air outlet 143 of the heat dissipation cavity 141 is arranged on the side of the heat exchanger 120 facing the fan assembly 110 to connect to the air inlet side 111, so that the air inlet 142 and the air outlet 143 of the heat dissipation cavity 141 are arranged across the heat exchanger 120, so that the 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 cavity 141 is the gas after heat exchange, such as in the cooling mode, the temperature of the airflow after heat exchange in the heat exchanger 120 is low, and condensation may be generated when entering the heat dissipation cavity 141. The condensation accumulates in the heat dissipation cavity 141 and is difficult to be discharged. It may also enter the inside of the electric control box 140, so that water droplets are easy to fall on the electrical components of the electric control box 140, which may easily cause malfunctions. In the heating mode, the temperature of the gas after heat exchange in the heat exchanger 120 is high, and it is difficult to achieve the heat dissipation effect when entering the heat dissipation cavity 141. Therefore, the air inlet 142 of the heat dissipation cavity 141 is directly connected to the main air inlet, which can reduce the possibility of the gas after heat exchange in the heat exchanger 120 entering the heat dissipation cavity 141 as much as possible, thereby reducing the possibility of condensation forming in the heat dissipation cavity 141.

[0037] The air outlet 143 of the heat dissipation cavity 141 is arranged on the side of the heat exchanger 120 facing the fan assembly 110 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 is directly connected to the air inlet side 111, which can also effectively speed up the flow rate of the airflow flowing through the heat dissipation cavity 141, thereby further speeding up the air flow on the surface of the electric control box 140, quickly taking away the heat generated by the electric control box 140, and helping the electric control box 140 to dissipate heat. Therefore, the air outlet 143 is arranged toward the air inlet 142 of the fan assembly 110, thereby further speeding up the flow rate of the airflow flowing through the heat dissipation cavity 141.

[0038] Furthermore, a plurality of air inlets 142 are provided, and the plurality of air inlets 142 are respectively provided on the bottom wall and the side wall of the heat dissipation cavity 141. Specifically, a plurality of air inlets 142 are provided 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, thereby further accelerating the air flow on the surface of the electric control box 140, quickly taking away the heat generated by the electric control box 140, and helping the electric control box 140 to dissipate heat. Multiple air inlets 142 are arranged on the bottom wall and side wall 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. It may be difficult to ensure the air intake of the heat dissipation cavity 141 if only the air inlet 142 is arranged on the side wall of the heat dissipation cavity 141. Therefore, the side wall of the heat dissipation cavity 141 is also provided with the air inlet 142, which not only increases the number of the air inlet 142, but also increases the air intake path, thereby ensuring the air flow through the heat dissipation cavity 141.

[0039] 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 electric control box 140 from the heat exchange cavity.

[0040] The technical solution of the present invention is as follows: the heat exchanger 120 is arranged 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 arranged 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, so as to help the electric control box 140 dissipate heat. The air inlet 142 of the heat dissipation cavity 141 is arranged on the side of the heat exchanger 120 away from the fan assembly 110 to be directly connected to the main air inlet, and the air outlet 143 of the heat dissipation cavity 141 is arranged on the side of the heat exchanger 120 facing the fan assembly 110 to be connected to the air inlet side 111, so that the air inlet 142 and the air outlet 143 of the heat dissipation cavity 141 are arranged across the heat exchanger 120, so that the air flowing through the heat dissipation cavity 141 does not undergo heat exchange in the heat exchanger 120 and is natural wind. The air inlet 142 of the heat dissipation cavity 141 is directly connected to the main air inlet, which can minimize the possibility of the gas after heat exchange in the heat exchanger 120 entering the heat dissipation cavity 141, thereby reducing the possibility of condensation forming in the heat dissipation cavity 141. Furthermore, the air outlet 143 of the heat dissipation cavity 141 is directly connected 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 is directly connected to the air inlet side 111, which can also effectively speed up the flow rate of the airflow flowing through the heat dissipation cavity 141, thereby further increasing the air flow on the surface of the electric control box 140, quickly taking away the heat generated by the electric control box 140, and helping the electric control box 140 to dissipate heat. Therefore, the air outlet 143 is arranged toward the air inlet 142 of the fan assembly 110, thereby further speeding up the flow rate of the airflow flowing through the heat dissipation cavity 141.

[0041] Refer again Figures 1 to 3 In one embodiment, the mounting member 130 is disposed on the top of the heat exchanger 120, and the electric control box 140 is fixed to the side of the mounting member 130 away from the heat exchanger 120. Specifically, the electric 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 shell. The corresponding electric control box 140 is disposed in the gap, which can effectively utilize the space in the shell, thereby effectively reducing the overall volume of the air conditioner 100, thereby reducing the occupied space of the air conditioner 100, and realizing the miniaturization of the air conditioner 100. The mounting member 130 is disposed on the top of the heat exchanger 120, and the electric control box 140 is fixed to the side of the mounting member 130 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.

[0042] 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, since the electric control box 140 is arranged above the heat exchanger 120, the mounting member 130 can be configured as a plate-like structure extending toward the heat exchanger 120, and the electric control box 140 is fixed on the side of the mounting member 130 away from the heat exchanger 120. Compared with the electric control box 140 being fixed on the side of the mounting member 130 facing the heat exchanger 120, the plate-like structure can also isolate the electric control box 140 from the heat exchanger 120, thereby ensuring the installation stability of the electric control box 140. Moreover, the mounting member 130 is integrally formed with the volute air duct 112, thereby reducing the splicing of the mounting member 130 and the volute air duct 112, reducing the installation process, and ensuring the installation stability of the mounting member 130, thereby ensuring the installation stability of the electric control box 140. Of course, in other embodiments, the mounting member 130 can also be snapped or bonded to the volute air duct 112 .

[0043] Furthermore, a support structure 160 is formed on the side of the fan assembly 110 facing the heat exchanger 120, and the support structure 160 is supported and abutted 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 electric control box 140, in order to further increase the installation stability of the electric control box 140, a support structure 160 is formed on the side of the fan assembly 110 facing the heat exchanger 120, and one end of the support structure 160 is supported and abutted against the bottom of the mounting member 130, and the other end is supported and abutted against the inner bottom wall of the shell, thereby effectively ensuring the installation stability of the mounting member 130. And the support structure 160 can be configured as a plate-like structure or a columnar structure arranged at intervals along the width direction of the mounting member 130, thereby effectively increasing the support strength of the mounting member 130 and ensuring the installation stability of the mounting member 130.

[0044] In one embodiment, the mounting member 130 includes a support plate 131 and a mounting plate 132 which are arranged at an angle, the outer wall of the electric control box 140, the mounting plate 132 and a part of the support plate 131 enclose a heat dissipation cavity 141, the air outlet 143 is arranged on the support plate 131, and the air inlet 142 is arranged on the support plate 131 and / or the mounting plate 132; and / or the electric 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 arranged at one end of the support plate 131, and the mounting plate 132 and the electric control box 140 are arranged relatively and spaced apart, so that the outer wall of the electric control box 140, the mounting plate 132 and part of the support plate 131 are enclosed to form a heat dissipation cavity 141, so that the radiator 150 is arranged in the heat dissipation cavity 141, so as to dissipate heat for the side wall of the electric control box 140 toward the mounting plate 132. The air outlet 143 is arranged on the support plate 131, so that the air outlet 131 is arranged 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. There are multiple air inlets 142, which are arranged on the support plate 131 and the mounting plate 132, and are enclosed by the electric control box 140, the mounting plate 132 and the support plate 131 to form the air inlet 142. Therefore, the air inlets 142 are arranged on the side wall and the bottom wall of the heat dissipation cavity 141, which not only increases the number of the air inlets 142, but also increases the air inlet path, thereby ensuring the air flow through the heat dissipation cavity 141.

[0045] Furthermore, the support plate 131 is provided with a support rib 133, and the support rib 133 abuts against the electric control box 140, so that the electric control box 140 is spaced apart from the support plate 131. Specifically, in order to further increase the heat dissipation effect of the electric control box 140, the support plate 131 is provided with a support rib 133, and a plurality of support ribs 133 extend along the width direction of the mounting plate 132, and the plurality of support ribs 133 and the support plate 131 together form a first heat dissipation channel 134, and the first heat dissipation channel 134 connects the main air inlet and the air outlet 143, thereby increasing the airflow velocity of the electric control box 140 toward the side wall surface of the support plate 131, thereby further increasing the heat dissipation area of ​​the electric control box 140 and increasing the heat dissipation efficiency of the electric control box 140.

[0046] In one embodiment, the mounting member 130 and the electric control box 140 are clamped together by a clamping structure; the mounting member 130 is fastened to the radiator 150 through the electric control box 140. Specifically, the electric control box 140 is mounted on the mounting member 130 by both the clamping structure and the fastener, thereby ensuring the installation stability of the electric control box 140 and facilitating the installation of the electric control box 140. The fastener can be configured as a fastening screw, a fastening bolt, etc.

[0047] Reference Figures 1 to 5 In one embodiment, the heat sink 150 includes a plurality of heat dissipation fins 161 spaced apart in the heat dissipation cavity 141. Specifically, the heat dissipation fins 161 have good thermal conductivity, so as to quickly conduct heat from the surface of the electric control box 140, and the plurality of heat dissipation fins 161 are spaced apart in the heat dissipation cavity 141, and a second heat dissipation channel 162 is formed between two adjacent heat dissipation fins 161, so as to further take away the heat from the surface of the heat dissipation fins 161, thereby improving the heat dissipation effect of the electric control box 140.

[0048] Furthermore, a plurality of heat dissipation fins 161 are extended from the air inlet 142 to the air outlet 143. Specifically, a plurality of heat dissipation fins 161 are extended from the air inlet 142 to the air outlet 143, that is, the second heat dissipation channel 162 is extended from the air inlet 142 to the air outlet 143, so that the second heat dissipation channel 162 is directly connected to the air inlet 142 and the air outlet 143, thereby reducing the possibility of airflow being blocked in the heat dissipation cavity 141, thereby effectively accelerating the air flow in the heat dissipation cavity 141, thereby improving the heat dissipation efficiency of the surface of the heat dissipation fins 161, and thereby improving the heat dissipation effect of the electric control box 140.

[0049] Furthermore, the surface of the heat dissipation fin 161 is configured as a wavy surface, thereby increasing the effective heat dissipation area of ​​the heat dissipation fin 161 , thereby improving the heat dissipation efficiency of the radiator 150 , and further improving the heat dissipation effect of the electric control box 140 .
