Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and specifically provides an outdoor unit of an air conditioner and an air conditioner. Background Art

[0002] When the outdoor unit of an air conditioner operates for a long time in a high-temperature environment, it may cause the electrical components of the electronic control system to malfunction or even be damaged due to excessive temperature, thereby affecting the stable operation of the entire air-conditioning system.

[0003] To improve the above phenomenon, a radiator is usually connected to the electronic control system and placed in the chamber where the condenser is located. In this way, the heat generated by the electrical components in the electronic control system will be transferred to the radiator. Then, during the operation of the outdoor unit fan, the external air flow passes through the condenser and the above radiator in sequence. During the process of the air flow passing through the radiator, part of the heat on the surface of the radiator is carried away, realizing the cooling of the electronic control system. However, since the air flow passing through the condenser already has a relatively high temperature, and the high-temperature air flow quickly sweeps across the surface of the radiator during the flowing process, the effect of convective heat transfer is not ideal. Therefore, the above solution still has the problem of poor heat dissipation effect.

[0004] In view of this, a new technical solution is needed in this field to solve the above problems. Summary of the Utility Model

[0005] The utility model aims to solve the above technical problems, that is, to solve the problem of poor heat dissipation effect of the existing outdoor unit of an air conditioner.

Detailed implementation manners

[0037] The following describes the preferred implementation manners of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not used to limit the protection scope of the present utility model. Those skilled in the art can adjust it as needed to adapt to specific application scenarios.

[0038] It should be noted that in the description of the present utility model, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings.

Therefore, it should not be construed as a limitation to the present utility model. In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0039] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] When the outdoor unit of an air conditioner operates for a long time in a high-temperature environment, it may cause the power devices in the electronic control component above the compressor to malfunction or be damaged due to high temperature. Therefore, in order to dissipate the heat of the power devices, a radiator is usually connected to the electronic control component to transfer the heat generated by the power devices themselves to the radiator. During the operation of the outdoor unit of the air conditioner, under the pressure difference formed by the fan, the outside air is sucked into the chamber of the outdoor unit, and the air flow passes through the condenser and the radiator of the electronic control component in sequence, taking away part of the heat on the surface of the radiator. Therefore, the above method increases the contact area between the power devices and the air through the radiator, thereby accelerating the transfer of heat to the surrounding air.

[0041] However, during the operation of the outdoor unit of the air conditioner, when the outside air flow passes through the condenser and enters the radiator, on the one hand, the air flow is in a laminar state, which will affect the convective heat transfer process between the air flow and the radiator, making the air flow unable to fully contact the surface of the radiator, thus reducing the heat transfer efficiency.

[0042] On the other hand, after the air flow passes through the condenser, its temperature has risen to a relatively high value. In this case, during the process of the air flow passing through the radiator, along the flow path of the air flow, its temperature will continue to rise. Therefore, even if the air flow passes through the radiator, no significant heat dissipation effect will be achieved.

[0043] Refer to Figure 1 and 2 , which is a schematic diagram of an outdoor unit of an air conditioner according to an embodiment of the present application, and it includes a casing 1, a condenser 2, an electronic control component 3, a partition member 5, and a fan 121.

[0044] Specifically, the casing 1 has opposite first side wall 11 and second side wall 12. When the outdoor unit of the air conditioner is in normal use, the first side wall 11 can be understood as the rear wall of the casing 1, and the second side wall 12 can be understood as the front wall of the casing 1. A partition 10 is fixedly arranged inside the casing 1, and the partition 10 divides the internal space of the casing 1 into a first chamber 101 and a second chamber 102.

[0045] Further, the condenser 2 is installed in the first chamber 101, and the condenser 2 is arranged close to the first side wall 11 of the casing 1. The part of the first side wall 11 corresponding to the condenser 2 has an air inlet, so that the outside air flow can enter the first chamber 101 through the air inlet and pass through the condenser 2. An air outlet 120 is arranged on the second side wall 12, and a fan 121 is installed at the air outlet 120. When the fan 121 operates, under the action of air pressure, the outside air flow enters the first chamber 101, passes through the condenser 2 and is discharged out of the first chamber 101 through the fan 121, so as to exchange heat with the condenser 2.

[0046] Further, the second chamber 102 is used for installing necessary component parts such as a compressor and a gas-liquid separator. The electronic control component 3 is installed at the top of the second chamber 102 and is electrically connected to the compressor. Specifically, the electronic control component 3 may include an electronic control box 31, a driving circuit board installed in the electronic control box 31, and various power devices electrically connected to the driving circuit board. One end of the electronic control component 3 extends into the first chamber 101 and is connected with a radiator 4, and the heat generated by the driving circuit board and the power devices in the electronic control box 31 can be transferred to the radiator 4.

[0047] Referring to Figure 3 , in an implementation manner of the present application, the radiator 4 includes a plurality of spaced-apart heat dissipation fins 41, and a channel for the air flow to pass through is formed between adjacent heat dissipation fins 41. When the radiator 4 is installed in the casing 1, the extending direction of the above channel is perpendicular to the surface of the condenser 2, so that the air flow passing through the condenser 2 can enter the above channel.

[0048] Referring to Figure 1 , a baffle 5 is arranged between the first side wall 11 and the radiator 4. The function of the baffle 5 is to disperse the air flow entering the casing 1 from the air inlet, so that the air flow changes from a laminar flow state to a turbulent flow state, or in other words, the air flow changes from flowing along parallel layers to moving in an irregular and chaotic manner.

[0049] The air flow in the turbulent flow state has greater irregularity. When such an air flow passes through the radiator 4, it can fully contact the surface of the radiator 4, extend the time for the air flow to pass through the surface of the radiator 4, thereby increasing the convective heat transfer coefficient between the air flow and the radiator 4, enhancing the heat transfer efficiency, and being beneficial to the stable operation of the electronic control component 3.

[0050] Further, in an implementation manner of the present application, when the partition member 5 is a plate-like member, it is preferably disposed in the space between the first side wall 11 and the condenser 2; when the partition member 5 is a member with a special shape, it is preferably disposed in the space between the condenser 2 and the radiator 4. In this way, according to the different shapes and designs of the partition member 5, it can be placed in different positions respectively, maximizing the utilization of the space inside the casing 1.

[0051] Of course, since the space between the condenser 2 and the radiator 4 is relatively large, when the partition member 5 is a plate member, it can also be disposed between them. The following describes the air flow path in this case.

[0052] Specifically, a gap for air flow is left between the partition member 5 and the partition plate 10. Refer to Figure 2 (The dotted line indicates the air flow path). When the external air flow enters the casing 1 from the air inlet of the first side wall 11 under the action of the fan 121, the air flow passes through the condenser 2 and is blocked by the partition member 5, and then turns and flows along the periphery of the partition member 5 towards the radiator 4.

[0053] When the air flow passes through the narrow gap between the partition plate 10 and the radiator 4, the air flow velocity increases. According to Bernoulli's principle, the increase in air flow velocity will cause the static pressure to decrease, so a low-pressure area is formed in this area.

[0054] In addition, in the limited space between the partition member 5 and the radiator 4, vortices are formed due to the increase in pressure and the change of direction of the air flow. In the vortex area, due to the relatively fast air flow velocity at the center and the decrease in pressure, a local low-pressure effect often occurs.

[0055] Under the action of the pressure difference, the air flow on the side of the radiator 4 away from the condenser 2 is also sucked into the radiator 4, thus forming a two-way air flow movement inside the radiator 4. This air flow movement mode can further improve the heat dissipation effect. Among them, the air flow on the side of the radiator 4 away from the condenser 2 may enter from the ventilation hole on the side wall of the casing 1, or may directly enter the casing 1 from the air inlet of the first side wall 11 without being blocked by the partition member 5.

[0056] It should be noted that there is also a gap between the partition member 5 and the bottom wall of the casing 1, so part of the air flow can also enter the radiator 4 from below the partition member 5 (not shown in the figure).

[0057] Further, the partition member 5 is connected to the electronic control box 31. The connection manner between the partition member 5 and the electronic control box 31 can have various forms. For example, screw or bolt connection, snap connection, welding connection or adhesive connection, or connection using a fixture or bracket, etc. The present application does not limit this.

[0058] In one embodiment, refer to Figure 4, the partition member 5 further includes a connecting portion 53 extending towards the direction of the electronic control box 31. The partition member 5 is connected to the electronic control box 31 through the connecting portion 53, and a third reinforcing rib 531 is provided on the connecting portion 53.

[0059] Specifically, the connecting portion 53 is responsible for fixing the partition member 5 on the electronic control box 31, so that it remains stable during operation and will not shift or loosen due to air flow impact or vibration. Since the design of the connecting portion 53 needs to withstand various mechanical forces between the partition member 5 and the electronic control box 31 to ensure that the partition member 5 will not be damaged or deformed during long-term use, in an implementation manner of the present application, a third reinforcing rib 531 is provided on the connecting portion 53 to improve its strength and rigidity.

[0060] In an implementation manner of the present application, the partition member 5, the connecting portion 53 and the electronic control box 31 are integrally formed. The integrated design can simplify the connection structure between components, help save space and improve the stability of the entire component.

[0061] In an implementation manner of the present application, the partition member 5 can also be connected to the housing 1.

[0062] In one embodiment, there is a certain interval between the partition member 5 and the electronic control box 31, and the orthographic projection of the partition member 5 on the surface of the condenser 2 covers the orthographic projections of the electronic control box 31 and the radiator 4 on the surface of the condenser 2.

[0063] In a specific implementation manner of the present application, the distance between the partition member 5 and the electronic control box 31 is 30 - 50 mm. The two sides of the partition member 5 protrude about 20 - 35 mm from the two side edges of the electronic control box 31 and the radiator 4. For example, the side of the partition member 5 close to the electronic control box 31 protrudes 20 - 30 mm from the edge of the electronic control box 31, and the side close to the radiator 4 protrudes 20 - 35 mm from the edge of the radiator 4. The distance between the bottom of the partition member 5 and the bottom of the radiator 4 is 40 - 60 mm, and the distance from the top to the top of the housing 1 is 10 - 20 mm.

[0064] By keeping an appropriate interval between the partition member 5 and the electronic control box 31 and the radiator 4, it can ensure that the partition member 5 effectively blocks the air flow and forms a larger low-pressure area. This design enables more low-temperature air flow to reversely enter the channels of the radiator 4, thereby improving the heat dissipation effect of the radiator 4.

[0065] In one embodiment, refer to Figure 4 and 5 , the surface of the partition member 5 is provided with a first reinforcing rib 511 and a second reinforcing rib 512 intersecting with the first reinforcing rib 511. The structure of providing reinforcing ribs on the surface of the partition member 5 helps to enhance the structural strength and stability of the partition member 5.

[0066] In one embodiment, refer to Figure 6and 7 The baffle 5 is a plate-shaped member, and a plurality of through holes 510 are provided on the plate-shaped member. The through holes 510 help to cause the air flow to be disturbed and mixed when passing through the baffle 5, thereby breaking the original laminar flow structure and forming a more complex and irregular turbulent flow pattern. Furthermore, it helps to increase the contact area between the air flow and the heat dissipation surface, improving the heat exchange efficiency and heat dissipation effect.

[0067] The arrangement of the through holes 510 on the baffle 5 can adopt various forms, and this application does not limit it.

[0068] For example, as shown in Figure 7 it is arranged in an array in a regular grid pattern, or the through holes 510 are arranged in a staggered manner on the baffle 5, that is, the holes in each column are located between the gaps of the holes in the previous column. This arrangement can break the straight flow of the air flow, enhance the disturbance and mixing of the air flow, and prompt the air flow to change from the laminar state to the turbulent state more quickly, thereby improving the heat exchange efficiency.

[0069] In one embodiment, referring to Figure 8 and 9 the baffle 5 is disposed between the condenser 2 and the radiator 4, and the baffle 5 includes a baffle plate 51 and turbulator bars 52 connected to the surface of the baffle plate 51. The turbulator bars 52 form a physical barrier on the baffle plate 51, changing the flow direction and speed of the air flow, making the air flow more disordered and irregular. This interference helps to prompt the air flow to change from the laminar state to the turbulent state, and further helps to increase the contact area between the air flow and the heat dissipation surface, improving the heat exchange efficiency and heat dissipation effect.

[0070] Furthermore, the arrangement of the turbulator bars 52 on the baffle plate 51 can adopt various forms, and this application does not limit it.

[0071] For example, as shown in Figure 9 it is arranged in an array in a regular grid pattern; or the turbulator bars 52 are arranged in a staggered manner on the baffle plate 51, that is, the turbulator bars 52 in each column are located between the gaps of the turbulator bars 52 in the previous column; or they are arranged in a completely irregular manner. This arrangement can break the straight flow of the air flow, enhance the disturbance and mixing of the air flow, and prompt the air flow to change from the laminar state to the turbulent state more quickly, thereby improving the heat exchange efficiency.

[0072] In one embodiment, referring to Figure 10 and 11, a baffle 5 is arranged between the condenser 2 and the radiator 4, and a spoiler 514 is arranged on the baffle 5. The function of the spoiler 514 is similar to that of the spoiler rod 52 in the above embodiment. That is, by forming a physical barrier on the baffle 5, it changes the flow direction and speed of the air flow, promotes the air flow to change from the laminar state to the turbulent state, and thus helps to increase the contact area between the air flow and the heat dissipation surface, improving the heat exchange efficiency and heat dissipation effect.

[0073] Furthermore, the specific shape and installation position of the spoiler 514 can adopt various forms. For example, the spoiler 514 can be arranged at different positions on the baffle 5, such as one end, the center or other suitable positions of the baffle 5; the spoiler 514 can adopt a flat plate or an arc-shaped plate or other shaped components, and the present application does not limit this.

[0074] In one implementation manner of the present application, as Figure 11 shown, the baffle 5 includes a plate-like member and a spoiler 514 protruding from one end of the plate-like member. The plate-like member is connected to the electric control box 31 through a connecting portion 53, providing a stable installation foundation for the spoiler 514. The spoiler 514 protrudes from one end of the plate-like member to form a prominent interference area, so as to increase the acting range of the spoiler 514 on the air flow, and help to generate more disturbances and mixing when the air flow passes through the plate-like member.

[0075] In one embodiment, referring to FIGS. 12 and 13, the baffle 5 is arranged between the condenser 2 and the radiator 4, and a spoiler grille 513 is arranged on the baffle 5. The spoiler grille 513 is usually composed of a plurality of slender strip-like structures, and these strip-like structures may be arranged vertically, horizontally or in other directions. The present application does not limit this.

[0076] The spoiler grille 513 disturbs the air flow by changing the flow direction and speed of the air flow, thereby increasing the mixing degree and turbulence degree of the air flow. This design helps to improve the disturbance of the air flow, and thus improves the heat exchange efficiency.

[0077] In one implementation manner of the present application, as Figure 13 shown, the spoiler grille 513 is provided with a deflector slope 5131. The deflector slope 5131 refers to an inclined surface provided on the grille, which is used to guide and change the flow direction of the air flow, thereby increasing the disturbance and mixing effect of the air flow, enhancing the turbulence degree of the air flow, and improving the heat exchange efficiency.

[0078] Furthermore, the cross-section of the deflector grille is designed in the shape of an airfoil. This shape is similar to the cross-section of an airplane wing, having a curved upper surface and a relatively flat lower surface. The design of the airfoil shape can effectively divide the air flow into upper and lower parts, and generate lift and air flow disturbance during the flow process.

[0079] In summary, the flow deflector grille 513 on the baffle 5 introduces air flow disturbance through its special structural design, thereby optimizing the flow characteristics of the air flow and improving the heat exchange efficiency.

[0080] This application also discloses an air conditioner, which includes the outdoor unit of the air conditioner in any of the above embodiments. The air conditioner includes an evaporator, a throttling device, and necessary components such as the condenser 2 and the compressor in the above outdoor unit of the air conditioner, which are not elaborated herein.

[0081] So far, the technical solution of the present utility model has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present utility model.
