Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning outdoor unit and an air conditioning device. Background Art

[0002] The electrical control board of the outdoor unit of the air conditioner is generally installed in the compressor cavity of the outdoor unit, and the power devices on the electrical control board will generate more heat when working.

[0003] In view of this, a common solution is to set a heat sink for the power device. For example, the outdoor unit of the air conditioner includes a housing, and a compressor, a condensing fan, a condenser and a waterproof electrical box arranged in the housing. The electrical control board can be installed in the waterproof electrical box, and the power device on the electrical control board is attached to the heat sink, and the heat sink can be exposed outside the electrical box through a through hole provided on the electrical box. Under the action of the condensing fan, the air in the housing passes through the condenser, flows through the heat sink and takes away the heat.

[0004] However, as the design layout of the electrical control board becomes more and more compact, the power loss of the power device becomes higher and higher, and the electrical control board using the above scheme will become less and less effective in cooling the power device. This is because this scheme only considers simply conducting the heat of the power device out through the radiator, without considering the influence of the outdoor unit air duct on the heat dissipation performance. Since the radiator is in the forced flow of air formed by the condensing fan in the outdoor unit, the structure of the air duct will affect the speed and direction of the air flowing through the radiator. There are many factors that affect the air duct, such as the direction of the condensing fan, the shape of the partition, the relative position of the radiator and the partition, the relative position of the radiator and the condenser, and the relative position of the radiator and the condensing fan and the air guide cover. In other words, when designing the heat dissipation of the electrical control board, the prior art only considers the size of the radiator, and does not take into account the factors affecting the air duct, so there is a problem of low heat dissipation efficiency. Summary of the invention

[0005] In view of the above problems, the embodiments of the present application provide an air-conditioning outdoor unit and an air-conditioning device, which take factors affecting the air duct into consideration during design, can improve the performance of the radiator, have a better heat dissipation effect on power devices, and have a higher heat dissipation efficiency.

[0016] In an optional implementation, a portion of the structure of the fan on a side facing the condenser protrudes from the air guide cover.

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] The existing air conditioner outdoor unit has the problem of poor heat dissipation effect and low heat dissipation efficiency for the power devices on the electrical control board. This is because, in the prior art, the air conditioner manufacturer only needs to reserve the installation position of the electrical box assembly during the design of the whole machine; and the air conditioner component manufacturer mainly considers the relationship between the size of the radiator and the thermal power consumption during the development of electrical control, and does not consider the heat dissipation effect of the cooling air duct defined by various components in the housing of the air conditioner outdoor unit on the radiator. This limits the heat dissipation effect of the radiator on the power devices. In the present application, the cooling air duct is optimized from the layout and relative position relationship of various components in the housing of the air conditioner outdoor unit. When designing the heat dissipation of the electrical control board, not only the size of the radiator is considered, but also the factors affecting the air duct are taken into account. Therefore, a better heat dissipation solution for the electrical control board can be designed to solve the problem of low heat dissipation efficiency.

[0055] The air conditioner outdoor unit of an embodiment of the present application is described below with reference to the accompanying drawings.

[0056] Embodiment 1

[0058] Reference Figure 1 , Figure 2In a first aspect, the present application provides an air conditioner outdoor unit 100, comprising a housing 110 and a compressor 111, a partition 120, a fan 130, a condenser 140 and an electrical box assembly 150 located in the housing 110, wherein the fan 130 and the compressor 111 are arranged along a first direction F, the condenser 140 is located to the side of the fan 130 and the compressor 111 and extends along the first direction F, the partition 120 extends along a height direction H of the housing 110, the partition 120 comprises a first partition portion 121, a second partition portion 122 and a guide portion 123 connected between the first partition portion 121 and the second partition portion 122, the first partition portion 121 The partition is between the fan 130 and the compressor 111, the second partition 122 is between the condenser 140 and the compressor 111, the electrical box assembly 150 includes a radiator 154, the electrical box assembly 150 is arranged on the top of the partition 120, and the guide portion 123 corresponds to the radiator 154, and the position of the radiator 154 meets the position of the partition 120;

[0059] When d3≤0.5d4, 0≤β≤α;

[0060] When d3≥0.5d4, α-15°≤β≤α+15°;

[0061] Among them, β is the angle between the side of the radiator 154 facing the condenser 140 and the fan 130 and the second direction, α is the angle between the surface of the guide portion 123 facing the condenser 140 and the second direction S, d3 is the length of the line connecting the two horizontal contour edges of the guide portion 123; d4 is the length dimension of the second blocking portion 122 along the first direction F; wherein the first direction F and the second direction S and the height direction H of the shell 110 are perpendicular to each other.

[0062] In the above scheme, the condenser 140 is arranged on the side of the fan 130 and the compressor 111, the first baffle 121 of the partition 120 is blocked between the fan 130 and the compressor 111, the second baffle 122 is blocked between the condenser 140 and the compressor 111, the guide part 123 is connected between the first baffle 121 and the second baffle 122, and the electrical box assembly 150 is arranged on the top of the guide part 123, and the guide part 123 corresponds to the radiator 154. In this way, after the air enters the condenser 140 from the outside, part of the air flows through the guide part 123 toward the radiator 154 on the electrical box assembly 150, and fully exchanges heat with the radiator 154. The air flowing through the radiator 154 flows to the fan 130 again, and is discharged from the shell 110 through the fan 130. The cooling air duct formed in this way has a gradually reduced diameter, which can better dissipate heat for the radiator 154; in addition, the positions of the radiator 154 and the partition 120 meet the following requirements:

[0063] When d3≤0.5d4, 0≤β≤α; when d3≥0.5d4, α-15°≤β≤α+15°;

[0064] That is, when the arrangement area of ​​the air guide 123 along the first direction F is small, the inclination of the heat sink 154 is smaller than the inclination of the air guide 123, so that the air guide 123 guides more air to the heat sink 154. When the arrangement area of ​​the air guide 123 along the first direction F is large, the air guide 123 can guide enough air to the heat sink 154, and the inclination of the heat sink 154 can be slightly increased, so that a larger range of the heat sink 154 is directly opposite to the condenser 140, thereby enabling the heat sink 154 to have a better heat dissipation effect on the power device 152, and improve the heat dissipation efficiency.

[0065] It should be noted that in the present application, the first direction F is a direction parallel to the front panel and the top panel of the shell 110, the second direction S is a direction parallel to the axial direction of the fan 130, and the height direction H of the shell 110 is perpendicular to both the first direction F and the second direction S mentioned above.

Among them, the condenser 140 can be located at the edge side of the hollow cavity, for example, Figure 2 On the upper side and the left side of the drawing shown, the condenser 140 may extend along the first direction F and the second direction S, and the side where the condenser 140 is located is the air inlet side of the air conditioner outdoor unit 100. Optionally, the size of the condenser 140 along the first direction F is larger than the diameter of the fan 130, so that the size of the cooling air duct on the air inlet side is larger than the size on the air outlet side.

[0067] The partition 120 is disposed in the housing 110, and can roughly divide the hollow cavity into a compressor cavity 112 and a fan cavity 113. The compressor cavity 112 is used to accommodate the compressor 111, and the fan cavity 113 is used to accommodate the fan 130. Specifically, as mentioned above, the partition 120 is disposed along the height direction of the housing 110, so that the partition 120 is a thin plate-like structure as a whole. For example, the partition 120 can be a bent sheet metal part as a whole. Figure 2 As an optional embodiment, the first barrier portion 121 extends along the second direction S, the second barrier portion 122 extends along the first direction F, and the guide portion 123 is a bending portion between the first barrier portion 121 and the second barrier portion 122, and can be located at the corner between the first barrier portion 121 and the second barrier portion 122. The guide portion 123 can be a straight bend or a curved bend.

[0068] Specifically, when the guide portion 123 is curved, refer to the following Figure 4aThe chord length of the arc portion of the bending portion is d3, and the angle between the chord and the second direction is α. When the guide portion 123 is a straight bend, refer to the following Figure 5a , the length of the hypotenuse of the bending portion is d3, and the angle between the hypotenuse and the second direction is α;

The control circuit board 151 and the power device 152 may be located in the electrical box 153, and the power device 152 is attached to the above-mentioned radiator 154 to dissipate heat for the power device 152. The radiator 154 may be exposed to the outside of the electrical box 153 through an avoidance hole provided on the electrical box 153.

The point belongs to the guide portion 123.

[0078] The relative position of the electrical box 153 in the second direction is determined by the distance from the radiator 154 to the fan 130, the distance from the radiator 154 to the fan shroud 131 and the rotation direction of the fan 130. Specifically, when observing from the side of the air conditioner outdoor unit 100 provided with the fan 130,
