The embodiments of the present application provide an air conditioner, which will be described in detail below.

First, referring to fig. 1, 1 and 2, fig. 1 shows an assembly diagram of an air conditioner in an embodiment of the present application, and fig. 2 shows an explosion diagram of the air conditioner in the embodiment of the present application, wherein the air conditioner includes:

an electronic control module 10;

a volute 20, the volute 20 having a first air inlet 21 and a first centrifugal chamber 22 communicating with the first air inlet 21;

the volute 20 further has a heat dissipation opening 23 communicated with the first centrifugal chamber 22, the electronic control module 10 has a heat dissipation portion 11, and the heat dissipation portion 11 extends into the first centrifugal chamber 22 through the heat dissipation opening 23.

Specifically, the electronic control module 10 is used for controlling the operation of the air conditioner electrical devices, such as the operation of the motor, the compressor, and the like. In some embodiments of the present application, the electronic control module 10 can implement a frequency conversion function, so that the operating power of electric devices such as a motor and a compressor can be adjusted along with the change of the indoor temperature, thereby achieving the purpose of energy saving.

The volute 20 is used to form a centrifugal chamber for mounting a wind wheel 24, and air is introduced by rotation of the wind wheel 24 and accelerated to blow into the chamber in the centrifugal chamber. The volute 20 has a first air inlet 21, and the volute 20 can introduce air through the first air inlet 21, generally, the first air inlet 21 is located at a side of the volute 20, so as to install the evaporator 30 at the side of the volute 20, and then the evaporator 30 with a larger volume can be adopted to increase the cooling and heating efficiency of the air conditioner. For example, the first air inlet 21 may be an opening with a square shape, a circular shape, or a combination thereof.

The evaporator 30 is used for evaporating the refrigerant flowing in to absorb heat and exchange heat with air, thereby reducing the temperature of the air to achieve the purpose of refrigeration. The evaporator 30 is installed at the first air inlet 21, and when the wind wheel 24 rotates, air enters the first centrifugal chamber 22 from the first air inlet 21 after heat exchange by the evaporator 30, and is finally discharged through the first air outlet 27. Illustratively, the evaporator 30 may be a flat plate type evaporator 30, a U-type evaporator 30, a-type or inverted a-type evaporator 30, or the like.

The volute 20 further has a first centrifugal chamber 22 and a heat dissipation port 23 communicated with the first centrifugal chamber 22, the electronic control module 10 has a heat dissipation portion 11, and the heat dissipation portion 11 extends into the first centrifugal chamber 22 through the heat dissipation port 23, for example, the heat dissipation portion 11 may be a heat dissipation structure in which a heat dissipation area can be increased and the heat dissipation structure extends into the first centrifugal chamber 22, such as a heat dissipation fin 111 and a heat dissipation corrugated structure. When the air conditioner works, the air which is subjected to heat exchange through the evaporator 30 flows into the first centrifugal chamber 22, so that the heat dissipation part 11 of the electronic control module 10 is dissipated, and the purpose of reducing the temperature of the electronic control module 10 is finally achieved.

This application is through setting up heat dissipation portion 11 to electrical control module 10, and stretch into first centrifugal chamber 22 with heat dissipation portion 11 through thermovent 23 in, when the air conditioner operation, evaporimeter 30 reduces the temperature of flowing into first centrifugal chamber 22 air from first air intake 21, make the lower air of temperature dispel the heat to heat dissipation portion 11 stretching into in first centrifugal chamber 22, thereby realized utilizing evaporimeter 30 to reduce the purpose of electrical control module 10 temperature, the overheated phenomenon of electrical control module 10 has effectually been avoided.

In some embodiments of the present application, referring to fig. 3, fig. 3 shows an exploded view of the electronic control module 10 in the embodiment of the present application, wherein the electronic control module 10 includes an electronic control box 12 and a circuit board 13 located inside the electronic control box 12, and the heat dissipation portion 11 includes a plurality of heat dissipation fins 111 protruding on an outer wall surface of the electronic control box 12. Because the circuit board 13 is installed in the electronic control box 12, the circuit board 13 can be better isolated from the outside and protected, so that the circuit board 13 is prevented from generating a condensation phenomenon, and meanwhile, the heat dissipation area of the electronic control module 10 can be increased by the plurality of heat dissipation fins 111, so that the heat dissipation efficiency of the electronic control module 10 is further improved.

Further, in order to avoid the influence of the heat dissipation portion 11 on the air flow in the first centrifugal chamber 22, and even increase the air flow resistance in the first centrifugal chamber 22, refer to fig. 2 and 3, wherein the wind wheel 24 is installed in the first centrifugal chamber 22, the adjacent heat dissipation fins 111 form the heat dissipation flow channel 112, the heat dissipation flow channel 112 is along the tangential direction of the rotation of the wind wheel 24, because the heat dissipation flow channel 112 is along the tangential direction of the rotation of the wind wheel 24, when the wind wheel 24 rotates, the air can smoothly flow through the heat dissipation flow channel 112, the resistance of the heat dissipation portion 11 on the air flow in the first centrifugal chamber 22 is avoided, and meanwhile, the amount of air flowing through the heat dissipation portion 11 can be increased, so as to achieve the purpose of improving the heat dissipation efficiency.

As an example, in order to further reduce the resistance effect of the heat sink 11 on the air flow in the first centrifugal chamber 22, in some embodiments of the present application, for example, for an embodiment in which the heat dissipation portion 11 includes heat dissipation fins 111 and heat dissipation flow channels 112, referring to fig. 4, fig. 4 shows a schematic cross-sectional view of the heat dissipation flow channels 112 in an embodiment of the present application, wherein, the heat dissipation runner 112 has an arc bottom surface 113 coaxial with the rotation axis of the wind wheel 24, because the arc bottom surface 113 is coaxial with the rotating shaft of the wind wheel 24, when the air flows through the arc bottom surface 113, the arc bottom surface 113 guides the air flow, thereby avoiding the phenomenon that the air directly washes the bottom of the heat dissipation flow channel 112 to reduce the air flow speed, and simultaneously the arc bottom surface 113 can increase the contact area with the air, and the heat exchange efficiency of the heat dissipation portion 11 can be improved while avoiding an increase in air flow resistance.

As another example, in order to further improve the heat dissipation efficiency of the heat dissipation portion 11, in some embodiments of the present application, for example, for an embodiment in which the heat dissipation portion 11 includes heat dissipation fins 111 and heat dissipation flow channels 112, referring to fig. 5, fig. 5 shows another schematic cross-sectional view of the heat dissipation flow channels 112 in the embodiment of the present application, wherein the bottom of the heat dissipation flow channels 112 has a plurality of protrusions 114 arranged at intervals, and the heat dissipation portion 11 can increase the contact area of air in the heat dissipation flow channels 112, thereby achieving the purpose of improving the heat dissipation efficiency of the heat dissipation portion 11.

It is understood that other structures for increasing the heat dissipation area may be disposed in the heat dissipation flow channel 112, such as heat dissipation protrusions 114 disposed on the side of the heat dissipation side sheet, to further improve the heat dissipation efficiency of the heat dissipation portion 11.

In order to facilitate heat conduction to the circuit board 13 to directly reduce the temperature of the circuit board 13, in some embodiments of the present application, for example, for an embodiment in which the electronic control module 10 includes the electronic control box 12 and the circuit board 13, refer to fig. 3, where the electronic control box 12 includes a box body 121 having a mounting opening 122 and a heat dissipation plate 123 covering the mounting opening 122, the heat dissipation portion 11 is located on a side of the heat dissipation plate 123 away from the box body 121, the circuit board 13 is attached to the heat dissipation plate 123, that is, one side of the heat dissipation plate 123 is attached to the circuit board 13, and the other side is provided with the heat dissipation portion 11, when the electronic control module 10 is subjected to heat dissipation, heat of the circuit board 13 is conducted to the heat dissipation portion 11 through the heat dissipation plate 123, and the heat dissipation portion 11 exchanges heat with air to directly take away heat of the circuit board 13, thereby achieving a purpose of conducting heat to the circuit board 13 to directly reduce the temperature of the circuit board 13.

Further, in order to avoid the air leakage at the heat dissipation opening 23 of the scroll casing 20, in some embodiments of the present application, for example, for an embodiment in which the electronic control box 12 includes a box body 121 having a mounting opening 122 and a heat dissipation plate 123 covering the mounting opening 122, refer to fig. 2 and fig. 3, wherein the heat dissipation plate 123 at least partially protrudes from the surface of the box body 121, and the size of the heat dissipation plate 123 corresponds to the size of the heat dissipation opening 23. When the electronic control module 10 is installed on the volute 20, the portion of the heat dissipation plate 123 protruding out of the surface of the box body 121 is embedded into the heat dissipation opening 23 of the volute 20, so that the sealing performance of the heat dissipation opening 23 is ensured, and the phenomenon that the electronic control module 10 is condensed due to the fact that air in the first centrifugal chamber 22 flows out of the volute 20 is avoided.

In some embodiments of the present application, for example, for the embodiment where the evaporator 30 is installed at the side of the volute 20, referring to fig. 2, in order to reduce the volume of the air conditioner, the electronic control module 10 may be installed at the back side of the volute 20, or the electronic control module 10 may also be installed at the top of the volute 20, and the electronic control module 10 at the back side or the top of the volute 20 may be compactly assembled with the evaporator 30, the volute 20, and the like, so as to achieve the purpose of reducing the volume of the air conditioner. Generally, the electronic control module 10 is preferably disposed on the back side of the volute 20, so that the longer edge of the electronic control module 10 can be vertical, and then the larger side surface of the electronic control module 10 can drop vertically, thereby avoiding the phenomenon that the surface of the volute 20 accumulates condensed water and permeates into the electronic control module 10 to cause short circuit of the circuit board 13.

With continued reference to fig. 1 and 2, the volute 20 further has a second centrifugal chamber 26 and a second air inlet 25, and in some embodiments, the second centrifugal chamber 26 and the second air inlet 25 may also serve as another set of fan modules, so as to achieve the purpose of increasing the air output of the air conditioner with the dual fan module. In other embodiments, for example, for the embodiment where the air conditioner is a mobile air conditioner, the second air inlet 25 and the second centrifugal chamber 26 may further be provided with a wind wheel 24 corresponding to the condenser 40, so as to realize the integration of the evaporator 30 and the condenser 40.

Wherein, the first air inlet 21 and the second air inlet 25 are located on the same side of the scroll casing 20; or the first and second air inlets 21 and 25 are located at opposite sides of the scroll case 20. When the first air inlet 21 and the second air inlet 25 are located on the same side of the volute 20, the air on the same side of the volute 20 is driven by the two groups of wind wheels 24 to flow fast, which is beneficial to introducing air into the first centrifugal chamber 22 and the second centrifugal chamber 26; when the first air inlet 21 and the second air inlet 25 are located at the opposite side of the volute 20, the two groups of wind wheels 24 respectively supply air from both sides, which is beneficial to the flow circulation of indoor air, and further accelerates indoor lowering. It is understood that the first air inlet 21 and the second air inlet 25 may be located at two adjacent sides.

Further, in some embodiments of the present application, for example, for the embodiment where the scroll casing 20 further has the second centrifugal chamber 26 and the second air inlet 25, the scroll casing 20 has the first air outlet 27 communicating with the first centrifugal chamber 22 and the second air outlet 28 communicating with the second centrifugal chamber 26, the first air outlet 27 and the second air outlet 28 are located at two opposite sides of the scroll casing 20, when the air conditioner operates, the first air outlet 27 flows out the cold air exchanging heat with the evaporator 30, and the second air outlet 28 flows out the hot air exchanging heat with the condenser 40, because the first air outlet 27 and the second air outlet 28 are located at two opposite sides of the scroll casing 20, the phenomenon that the cold air at the first air outlet 27 exchanges heat with the hot air controlled by the second air outlet to decrease the cooling efficiency of the air conditioner can be avoided.

In some embodiments of the present application, for example, for the embodiment in which the air conditioner is a mobile air conditioner, the air conditioner further includes a condenser 40, the condenser 40 is installed at the second air inlet 25 of the scroll casing 20, the condenser 40 is connected to the evaporator 30 through a circulation line, when the refrigerant passes through the condenser 40, the refrigerant releases heat and exchanges heat with air, and the air with the increased temperature flows into the second centrifugal chamber 26 through the second air inlet 25 and is discharged through the second air outlet 28, thereby finally forming the mobile air conditioner in which the condenser 40 and the evaporator 30 are integrated.
