Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

Under the influence of greenhouse effect, outdoor air temperature is higher and higher, and if the heat exchanger of the air conditioner external unit is insufficient in heat dissipation, the air conditioner external unit can be stopped due to high-temperature protection. When the traditional air conditioner external unit dissipates heat of the heat exchanger, a fan is generally utilized to form negative pressure in the air conditioner external unit, and external air is sucked to exchange heat of the heat exchanger under the action of the negative pressure. However, the mode of taking the pressure difference of the sucked air as heat exchange power is easy to cause the airflow velocity acting on the heat exchanger to be small, the heat exchange performance is poor, and the normal operation of the air conditioner is seriously affected.

Based on this, in order to solve the problem that the heat exchange performance of the conventional air conditioner outdoor unit 100 is poor and the normal operation of the whole machine is affected, the applicant has designed an air conditioner outdoor unit 100 through intensive research. Referring to fig. 1 and 2, an air conditioner outdoor unit 100 includes: the heat exchanger 30 and the fan 20, the casing 10 is provided with an air inlet 11 and an air outlet 12, and the heat exchanger 30 is arranged in the casing 10 and comprises a first part 31. The fan 20 is disposed in the casing 10, and an air outlet end of the fan 20 is disposed toward the first component 31 along a preset direction X.

In the air conditioner outdoor unit 100, during the heat exchange process, the fan 20 is used to suck the external air from the air inlet 11 and discharge the external air from the air outlet 12, so as to realize heat exchange and temperature reduction of the heat exchanger 30. Since the air outlet end of the fan 20 is disposed towards the first component 31 along the preset direction X, the air output by the fan 20 can be directly blown towards the first component 31 along the preset direction X, so as to directly dissipate heat. So, compare in the traditional mode that relies on the pressure differential that induced drafts, the air flow rate on the first part 31 can be accelerated to the heat dissipation mode of blowing of this application, promotes the heat dispersion of heat exchanger 30, reduces the outer machine 100 of air conditioner and because of the probability that high temperature protection shut down, guarantees the steady operation of complete machine.

It should be noted that, the air outlet end of the fan 20 is understood to be an end of the fan 20 capable of outputting an air flow, for example: taking the axial flow fan 20 as an example, the air outlet end of the fan 20 is the end with the fan blades 21 on the axial flow fan 20. Of course, the fan 20 of the present application may also be other types of fans 20, such as centrifugal fans 20, and the like.

The air outlet end of the fan 20 is disposed towards the first component 31, which indicates that the air flow output by the fan 20 can be blown onto the first component 31 along the preset direction X. In order to make the wind outlet energy on the fan 20 act on the first component 31 better, a certain distance should be kept between the wind outlet end of the fan 20 and the first component 31. If the spacing is too close, the first member 31 receives an excessive impact force, which leads to an easy destabilization of the structure; if the distance is too large, the flow velocity of the air flow acting on the first member 31 decreases to affect the heat radiation effect.

The preset direction X refers to the direction of the air flow from the air outlet end of the fan 20 to the first member 31, and may also be understood as the direction of the interval between the air outlet end of the fan 20 and the first member 31.

In addition, the air flow blown onto the first component 31 by the fan 20 is wound around the first component 31 on the side facing away from the fan 20 along the circumferential direction of the first component 31 after heat exchange, and finally discharged from the air outlet 12.

It should be noted that, the positions of the air outlet 12 and the air inlet 11 on the casing 10 are designed in various ways, so long as the requirement that the outside air stably enters and exits the casing 10 is satisfied, for example: the air outlet 12 and the air inlet 11 are respectively arranged on different sides of the shell 10; alternatively, the air outlet 12 and the air inlet 11 are both positioned on the same side of the casing 10, but a certain distance is arranged between the air outlet 12 and the air inlet 11, so that the mutual influence of two airflows is avoided.

Further, referring to fig. 2, the air outlets 12 are distributed on a side of the first member 31 facing away from the fan 20. Therefore, the air outlet 12 is disposed on the side of the first component 31 facing away from the fan 20, so that the air flow exchanging heat with the first component 31 can bypass the first component 31 and be directly discharged from the air outlet 12, thereby accelerating the flow of the air flow, increasing the negative pressure in the casing 10, accelerating the intake rate of the external air, and improving the heat dissipation effect.

The number of the air outlets 12 may be one or more. When the number of the air outlets 12 is plural, the distribution of the air outlets 12 on the casing 10 is plural, for example: the distribution mode can be, but is not limited to, matrix arrangement, circular ring interval arrangement and the like.

Meanwhile, the shape of the air outlet 12 may have various designs, such as: the shape of the air outlet 12 may be, but is not limited to, circular, oval, square, pentagonal, etc., although it may be of irregular design.

Further, referring to fig. 2, the air outlet 12 includes more than two air outlets, and at least a portion of the air outlet 12 overlaps with the projection of the first member 31 along the predetermined direction X. When all the air outlets 12 are arranged on the side of the first part 31 facing away from the fan 20, the air outlets 12 may be roughly divided into two types, one type of air outlets 12 being distributed around the periphery of the first part 31; the other type of air outlets 12 are distributed opposite to the first part 31 in the preset direction X, and it is also understood that the projection of the first part 31 along the preset direction X can cover the air outlets 12 of the part. For the air outlets 12 distributed around the periphery of the first part 31, the air flow can flow to both edges of the first part 31 and then can be discharged from the air outlets 12; for the other type of air outlets 12 (i.e., the air outlets 12 distributed in the preset direction X and located opposite to the first member 31), the air flow should be wound around a side of the first member 31 opposite to the first member 31 to be discharged, so that the air flow is in a flow-collecting state on the side of the first member 31 opposite to the fan 20 before being discharged.

For this reason, the projection of at least a part of the air outlet 12 in the preset direction X and the projection of the first member 31 in the preset direction X are overlapped, so that the air flow can sufficiently contact with the first member 31, and the heat dissipation performance is improved. In particular, in some embodiments, the projection of all air outlets 12 in the preset direction X overlaps the projection of first part 31 in preset direction X.

In some embodiments, referring to fig. 2, the heat exchanger 30 further includes a second component 32 coupled to the first component 31. The second part 32 is located at one side of the blower 20 and extends in a predetermined direction X. It can be seen that the first component 31 directly exchanges heat with the air flow output by the fan 20; and the heat dissipation of the second component 32 is mainly performed by sucking external air to dissipate the heat according to the pressure difference between the inside and outside of the casing 10. So, this application utilizes the mode that induced drafts and bloies and combine together, improves the heat exchange efficiency on the heat exchanger 30 greatly, promotes the radiating effect on the outer machine 100 of air conditioner.

The number of the second members 32 may be one or more. When the second component 32 is one, the heat exchanger 30 generally assumes a "7" shaped configuration overall; when the second member 32 is plural, all of the second members 32 may be disposed around the circumference of the blower 20 on the first member 31, or the like.

The manner in which the second member 32 is attached to the first member 31 may be a fabricated manner; or can be integrally formed. When the second component 32 and the first component 31 are connected in a fitting manner, the connection manner may be, but is not limited to, bolting, clamping, welding, etc.; when the second member 32 and the first member 31 are integrally formed, the connection manner may be, but is not limited to, bending, stamping, die casting, etc.

Further, referring to fig. 2, the air inlet 11 includes more than two air inlets, and at least a portion of the air inlets 11 are distributed on a side of the second member 32 facing away from the fan 20. Thus, the air sucked from the partial air inlet 11 can directly act on the second component 32, which is beneficial to improving the air suction type heat exchange efficiency on the second component 32 and improving the heat dissipation effect of the air conditioner outdoor unit 100.

Further, referring to fig. 2, the second component 32 includes more than two second components 32, wherein the two second components 32 are respectively connected to opposite ends of the first component 31, and the air inlets 11 are respectively disposed at the sides of the second components facing away from the fan 20. It can be seen that at least two second members 32 are respectively connected to opposite ends of the first member 31 among all the second members 32 to form the inverted U-shaped heat exchanger 30. Of course, if the second members 32 are more than three, the remaining second members 32 may be connected to at least one end of the first member 31, such that one end of the first member 31 is connected with a plurality of second members 32; alternatively, the remaining second member 32 may be attached to other portions of the first member 31 and disposed about the fan 20, etc.

In this embodiment, at least two second components 32 are respectively connected to opposite ends of the first component 31, and it is ensured that an air inlet 11 is correspondingly formed on one side of each second component 32 facing away from the fan 20, so that at least two sides of the heat exchanger 30 can be directly subjected to induced draft heat exchange, the heat exchange efficiency is greatly improved, and stable operation of the air conditioner at high temperature is satisfied.

Specifically, referring to fig. 3, two second parts 32 are provided, and the two second parts 32 are respectively connected to opposite ends of the first part 31 to form an inverted U-shaped heat exchanger 30. At this time, the heat exchanger 30 is reversely buckled above the fan 20, and the air inlets 11 are correspondingly arranged on one side of each second part 32 facing away from the fan 20.

In some embodiments, referring to fig. 3, the air conditioner outdoor unit 100 further includes a pod 40. The air guide sleeve 40 is disposed around the outer periphery of the air outlet end of the fan 20, and is used for guiding the air output by the fan 20 to the first component 31. In this way, by using the wind scooper, the flow path of the air flow is planned, so that more air flow is ensured to be directly blown to the first component 31, the flow speed of the air flow is increased, and the heat exchange efficiency is improved.

It should be noted that, the air guide sleeve 40 has a ring structure, and is disposed around the outer periphery of the air outlet end of the fan 20, and various embodiments thereof include: the fan blade 21 part of the fan 20 is entirely covered in the air guide sleeve 40; alternatively, one end of the shroud 40 covers the outer periphery of one end of the fan 21, and so on. Meanwhile, a certain space should be reserved between the air guide sleeve 40 and the first component 31, so that the air flow after heat exchange can bypass the first component 31 and be discharged from the air outlet 12.

It should be further noted that the shape of the pod 40 may have various designs, such as: it may be designed into cylindrical, triangular prism, quadrangular prism or other columnar structure.

In some embodiments, referring to fig. 4, a drainage portion 16 is provided on an edge of the air outlet 12, and the drainage portion 16 extends in a direction toward the inside of the casing 10 and away from a middle portion of the air outlet 12. As can be seen from this, the flow guide portion 16 has an inclined structure with respect to the air outlet 12, and the inclined structure may be a flat inclined surface or a curved surface inclined. Since the air outlet direction of the fan 20 is at an angle to the horizontal direction when the fan is outputting air to the first component 31, for example: the airflow output by the axial flow fan is spiral and forms an included angle with the horizontal direction, so that the airflow flows along the direction of the drainage part 16 by utilizing the inclined drainage part 16, the resistance of wind is reduced, the airflow in the casing 10 is smoothly led out of the air outlet 12, the negative pressure value in the casing 10 is increased, the airflow velocity in the casing 10 is accelerated, and the heat exchange efficiency on the heat exchanger 30 is improved.

The number of the drainage portions 16 may be one or more. When the number of the flow guiding portions 16 is plural, all the flow guiding portions 16 may be disposed at intervals along the circumferential direction of the air outlet 12, for example: taking the square air outlet 12 as an example, two flow guiding portions 16 may be respectively disposed on two opposite edges of the air outlet 12, and each flow guiding portion 16 extends along a middle portion away from the air outlet 12 so as to guide the peripheral air flow into the air outlet 12.

When the drainage portion 16 has a plate-like structure, an included angle θ is formed between the drainage portion 16 and a side surface of the casing 10 facing the first component 31, where the included angle θ may be 0 ° to 90 ° (excluding 0 ° and 90 °), for example: the included angle θ may be, but is not limited to, 60 and the like. When the included angle θ is 60 °, the air conditioner external unit 100 may be subjected to an air-out simulation experiment, and in the simulation experiment, it is known that the air-out amount can be increased by 20% by providing the drainage portion 16 with the included angle of 60 °.

Alternatively, the drainage portion 16 may be disposed on the edge of the air outlet 12 by, but not limited to, bolting, clamping, bonding, welding, etc. assembly; of course, the method may be an integral molding method such as bending and die casting.

In some embodiments, referring to fig. 2, the casing 10 includes a base 15, a casing 13 surrounding the base 15, and a top cover 14 covering an end of the casing 13 opposite to the base 15. The air outlet 12 is arranged on the top cover 14, the first part 31 is arranged between the top cover 14 and the air outlet end of the fan 20, and the air inlet 11 is arranged on the shell 13. It can be seen that during the heat dissipation process, the outside air is sucked from the housing 13; then blowing toward the first member 31 by the blower 20; the air flow after heat exchange bypasses the first part 31 and is discharged from the air outlet 12 of the top cover 14, so that the heat dissipation effect of the air conditioner outdoor unit 100 is higher.

Optionally, the housing 13 may be connected to the top cover 14 and the base 15 in various manners, such as: bolted connection, clamping connection, riveting, welding, bonding, integral molding and the like.

It should be noted that the housing 13 has various structural designs, such as: the housing 13 may be designed in a cylindrical structure, a triangular prism structure, a quadrangular prism structure, etc.

In some embodiments, referring to fig. 2, the housing 13 includes a front side plate 132, a rear side plate 133, and two side guard plates 131 that are connected between the front side plate 132 and the rear side plate 133 at intervals. The heat exchanger 30 includes two second members 32, and the two second members 32 are respectively connected to the first members 31 and are respectively disposed corresponding to the two side shields 131. Each side guard 131 is provided with an air inlet 11. Meanwhile, the side guard plate 131 may have a plurality of air inlets 11, and all the air inlets 11 may be arranged in a matrix, a circular ring at intervals, or in a random close-packed manner.

In addition, during actual installation, the side guard 131 is prevented from being set toward the wall as much as possible, for example: the rear side plate 133 may be disposed against the wall to ensure that one side of the side shield 131 has a sufficient space. In this way, during heat dissipation, the external air can more smoothly enter from the air inlet 11 of the side guard plate 131, so as to improve the air intake in the casing 10 and the heat dissipation effect of the heat exchanger 30.

In some embodiments, referring to fig. 3, in order to stably mount the blower 20 and raise the blower 20 so that the blower 20 can blow air to the first part 31 better, a bracket 50 may be disposed in the casing 10, and the blower 20 may be fixed on the bracket 50, so that the blower 20 can stably blow air to the first part 31, and heat exchange efficiency is improved. In particular, in some embodiments, the bracket 50 is fixed to the base 15 and the blower 20 is mounted to the bracket 50.

In some embodiments, the air conditioner external 100 further includes a compressor 60, the compressor 60 being in communication with the heat exchanger 30. Meanwhile, the air conditioner external unit 100 further includes an electronic control box 70, and the electronic control box 70 is disposed in the cabinet 10.

In some embodiments, referring to fig. 2, the fan 20 is an axial flow fan 20, and the axial direction of the fan 20 is consistent with the preset direction X.

In some embodiments, an air conditioner includes the air conditioner outdoor unit 100 of any of the above.

In the air conditioner, the air conditioner external unit 100 is adopted, and in the heat exchange process, the fan 20 is used for sucking external air from the air inlet 11 and discharging the external air from the air outlet 12, so that the heat exchange and the temperature reduction of the heat exchanger 30 are realized. Because the air outlet end of the fan 20 is arranged towards the first component 31 along the preset direction X, the air output by the fan 20 can be directly blown towards the first component 31 along the preset direction X, so that the direct heat radiation is realized, the air flow rate on the first component 31 is quickened, the heat radiation performance of the heat exchanger 30 is improved, the probability that the air conditioner outdoor unit 100 is stopped due to high-temperature protection is reduced, and the stable operation of the whole machine is ensured.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
