The vertical bracket 21 can be used for installing a fan, and the fixing plate 20 is connected with the vertical bracket 21 through the first installation part 201 on the side edge, so that the fixing plate 20 can be conveniently detached from the vertical bracket 21. The fixing plate 20 may be connected to the top of the housing 1 to make the vertical stand 21 stand more stably. Alternatively, the housing 1 has a rectangular parallelepiped shape, and the fixing plate 20 is disposed horizontally. In this way, the contact area of the fixing plate 20 with the top of the housing 1 can be larger, so that the fixing effect of the fan bracket 2 is enhanced.
In some embodiments, the first mounting portion 201 is bent downward relative to the fixing plate 20. The first mounting portion 201 is bent downward relative to the fixing plate 20, so that it can be closer to the vertical bracket 21, and is conveniently connected to the vertical bracket 21. Alternatively, the first mounting part 201 is plate-shaped. First installation department 201 can laminate the surface of vertical support 21, area of contact between increase and the vertical support 21, and then the effort between reinforcing and the vertical support 21, when both are connected state, can make between fan support 2 and the fixed plate 20 firm more stable.
In some embodiments, the vertical support 21 comprises: a base vertically disposed in the accommodating space 10; and the second mounting part 211 is arranged at the top of the base body and detachably connected with the first mounting part 201. The base is vertically disposed in the accommodating space 10 and configured to mount a fan of an outdoor unit of an air conditioner. The second mounting portion 211 is provided at the top of the base body to avoid spatial interference with components for mounting the blower on the base body. The second mounting portion 211 is detachably connected to the first mounting portion 201, and when the fixing plate 20 needs to be mounted or dismounted, only the second mounting portion 211 needs to be connected to or dismounted from the first mounting portion 201.
Alternatively, the first mounting part 201 is provided with a card slot, and the second mounting part 211 is snapped into the card slot. The first mounting portion 201 and the second mounting portion 211 are detachably connected in a clamping manner. When the fixing plate 20 and the vertical bracket 21 need to be installed, the second installation part 211 corresponds to the clamping groove position, pressure is applied to the first installation part 201, the second installation part 211 deforms and is extruded into the clamping groove, and connection with the first installation part 201 is completed. When the fixing plate 20 and the fixing bracket need to be detached, the first mounting portion 201 is pulled outwards to separate the second mounting portion 211 from the clamping groove, and the first mounting portion 201 is separated from the second mounting portion 211.
In some embodiments, the second mounting portion 211 and the first mounting portion 201 are both plate-shaped and attached to each other. The second mounting part 211 and the first mounting part 201 are both plate-shaped and are attached to each other, so that the contact area between the second mounting part 211 and the first mounting part 201 is increased, the acting force between the second mounting part 211 and the first mounting part 201 is enhanced, and the fixing effect between the vertical bracket 21 and the fixing plate 20 is firmer and more stable.
In some embodiments, the second mounting portion 211 is larger in area than the first mounting portion 201. On the basis of realizing the firm connection between the vertical bracket 21 and the fixing plate 20, the area of the first mounting part 201 is reduced, and the material usage of the fixing plate 20 is saved. In some embodiments, the second mounting portion 211 and the first mounting portion 201 are each provided with a mounting hole, and the mounting hole of the second mounting portion 211 is opposite to the center of the mounting hole of the first mounting portion 201 and is connected by a bolt. Like this, when installation fixed plate 20 and vertical support 21, can laminate first installation department 201 and second installation department 211 mutually earlier, make first installation department 201 and second installation department 211 keep relatively stable, and the mounting hole center that will be located above that is relative, then adopt the bolt to run through the mounting hole can, convenient operation.
In some embodiments, as shown in fig. 6, the other side of the fixing plate 20 is provided with a connection mechanism 22, and the connection mechanism 22 is connected with the heat dissipation member 3. Thus, the heat dissipation member 3 can be connected to the fixing plate 20, enhancing the fixing effect of the heat dissipation member 3. The other side of the fixing plate 20 is provided with the connecting mechanism 22, so that the connecting mechanism 22 and the first mounting portion 201 are located at different sides, and the connecting mechanism 22 is prevented from interfering with the first mounting portion 201 when the heat dissipation member 3 is connected, and the connection between the first mounting portion 201 and the second mounting portion 211 is prevented from being affected.
In some embodiments, the connection mechanism 22 includes: a pressing plate which is arranged close to the surface of the heat dissipation member 3 and is provided with a through hole; wherein the heat dissipating member 3 is provided with a protrusion penetrating the through hole, and the diameter of the free end of the protrusion is larger than that of the through hole.
The pressing plate is close to the surface of the heat dissipation component 3, the contact area of the pressing plate and the heat dissipation component 3 is large, and the phenomenon that the heat dissipation component 3 overturns relative to the pressing plate to cause unstable structure can be avoided. The protruding part of the heat dissipation member 3 penetrates through the through hole of the pressing plate, so that the transverse relative position between the heat dissipation member 3 and the pressing plate can be limited, and the heat dissipation member 3 and the pressing plate are prevented from being greatly transversely deviated. The diameter of the free end of the protruding part is larger than that of the through hole, so that the protruding part can be prevented from being separated from the through hole, and the heat dissipation component 3 can be limited. Moreover, because the pressure plate is not rigidly connected with the heat dissipation member 3 but can generate longitudinal relative displacement, when the fan bracket 2 vibrates, the fixing plate 20 is driven to vibrate, and when the heat dissipation member 3 receives the acting force of the fixing plate 20, the acting force can be buffered by longitudinally moving relative to the fixing plate 20, so that the heat dissipation member 3 is prevented from being broken and damaged due to the action of the force.
In some embodiments, a resilient gasket is provided between the pressure plate and the heat dissipating member 3. The elastic gasket can further buffer the acting force between the pressing plate and the heat dissipation component 3, and avoid collision and friction when the pressing plate and the heat dissipation component 3 move longitudinally relative to each other, so that the service lives of the heat dissipation component 3 and the pressing plate are prolonged. Optionally, the elastic pad is made of rubber. The rubber material is relatively wear-resistant and elastic, and can buffer the acting force between the pressing plate and the heat dissipation member 3.
In some embodiments, as shown in fig. 1 and 2, the heat dissipating member 3 is flexibly connected to the fixing plate 20 through a connector 7, the connector 7 includes a first connector 71 and a second connector 72, the first connector 71 is flexibly connected to the fixing plate 20, and the second connector 72 is flexibly connected to the heat dissipating member 3.
The heat dissipation component 3 is connected with the heating component for heat dissipation, the heat dissipation component 3 is also connected with the fan support 2 through the connecting piece 7, wherein the connecting piece 7 is flexibly connected with the fixing plate 20 and the heat dissipation component 3, when the fan support 2 vibrates, the connecting piece 7 can buffer acting force between the heat dissipation component 3 and the fan support 2, and the heat dissipation component 3 is prevented from deforming or breaking due to acting force of the fan support 2 and the heating component.
Alternatively, the first connection portion 71 and the fixed plate 20 are connected by a spring, and the second connection portion 72 and the heat dissipation member 3 are connected by a spring. When fan support 2 takes place to vibrate, produce the effort to the spring, the spring takes place to deform and cushions this effort, and through the transmission of first connecting portion 71, second connecting portion 72 and spring, the effort that radiating member 3 received weakens greatly to avoid producing and warp, cause the damage.
In some embodiments, the first connection portion 71 includes: a first plate member attached to the fixing plate 20; the second plate is bent relative to the first plate and is provided with an opening; wherein, the fixing plate 20 is provided with a first hook portion 202, and the first hook portion 202 penetrates through the opening to be hooked with the first connecting portion 71. First plate and fixed plate 20 are laminated mutually, and the area of contact with fixed plate 20 is great, can avoid first plate relative fixed plate 20 to take place the upset of great angle, causes connecting piece 7 unstability. The fixing plate 20 is hooked with the first connecting portion 71 by the first hook 202 penetrating through the opening of the second plate. The hooking allows a certain degree of relative movement between the first plate and the fixing plate 20, thereby buffering the acting force of the fixing plate 20 on the first plate. Optionally, the first hook 202 is disposed on the top of the fixing plate 20, and the first plate is attached to the top of the fixing plate 20. The first hook 202 is disposed on the top of the fixing plate 20 to facilitate the connection between the first plate and the fixing plate 20. The second plate is bent relative to the first plate, when the first plate receives the acting force from the fixing plate 20, the first plate transmits the acting force to the second plate, and when the connecting piece 7 gives the acting force to the second plate in the opposite direction, the second plate can be further bent relative to the first plate to buffer the acting force between the first plate and the connecting piece 7.
In some embodiments, the first hook 202 has a plate shape, and a buffer space is formed between the first hook 202 and the first plate. The buffer space allows relative movement between the fixing plate 20 and the connecting member 7, thereby buffering the interaction force between the fixing plate 20 and the first connecting member 7. Optionally, the opening extends to the first plate. When the fixing plate 20 and the first connecting member 7 move relatively, the first hook 202 and the first plate move relatively, and when the first plate is far away from the fixing plate 20 to a certain extent, the first hook 202 abuts against the first plate to prevent the first plate from further far away; when the first plate member approaches the fixing plate 20 to a certain extent, the first plate member abuts against the surface of the fixing plate 20 to prevent the first plate member from further approaching. The plate-shaped first hook 202 is beneficial to limiting the first plate, and the first plate is kept stable, so that the first plate is prevented from being overturned by a larger margin relative to the fixing plate 20.
In some embodiments, the buffer space is provided with a resilient gasket. The elastic pad can further buffer the acting force between the first plate and the first hook 202, and prevent the first plate and the first hook 202 from colliding and rubbing when moving relatively, so as to protect the fixing plate 20 and the first plate. Optionally, the elastic pad is made of rubber. The rubber material is relatively wear-resistant, has elasticity, and can cushion the acting force between the first plate and the first hook 202. Optionally, the resilient pad is disposed on the first plate. When manufacturing the connector 7, the elastic gasket can be manufactured together, which is easier than manufacturing the fixing plate 20 of the fan bracket 2 having the elastic gasket.
In some embodiments, the second connection portion 72 and the first connection portion 71 are in an axisymmetrical structure, and the heat dissipation member 3 is provided with a second hook 320 that is engaged with the second connection portion 72. The heat dissipation member 3 is hooked with the second connection portion 72 through the second hook 320, so that the second connection portion 72 can move relative to the heat dissipation member 3, and further, the acting force between the second connection portion 72 and the heat dissipation member 3 is buffered. The first coupling portion 71 is axisymmetrical to the second coupling portion 72, and the first hook portion 202 is opposite to the second hook portion 320, so that the coupling member 7 is not easily detached from the fixing plate 20 and the heat dissipation member 3.
Optionally, the second connection portion 72 includes: a third plate attached to the heat radiation member 3; the fourth plate is bent relative to the third plate and is provided with an opening; wherein, the heat dissipating member 3 is provided with a second hook 320, and the second hook 320 penetrates through the opening of the third plate to be hooked with the second connecting portion 72. In this way, the hooking between the second hook 320 and the second connection portion 72 can be achieved. Optionally, the heat dissipating member 3 is plate-shaped, and the third plate is attached to the surface of the heat dissipating member 3. Thus, the contact area between the heat dissipation member 3 and the third plate is increased, the acting force between the heat dissipation member 3 and the third plate is enhanced, the third connecting part is prevented from being overturned to a greater extent relative to the surface of the heat dissipation member 3, and the connecting part 7 is more stable.
In some embodiments, the first connection portion 71 and the second connection portion 72 are connected by a transition portion 73 and form a zigzag shape. The transition portion 73 connects the first connection portion 71 and the second connection portion 72, and transmits a force between the first connection portion 71 and the second connection portion 72. Alternatively, the transition portion 73 is connected to the second plate at one end and to the third plate at the other end. The force generated by the fixed plate 20 is transmitted from the first plate to the second plate and then to the third plate and the fourth plate in turn via the transition portion 73. The force generated by the heat dissipation member 3 is transmitted from the third plate to the fourth plate, and then sequentially transmitted to the second plate and the first plate through the transition portion 73. Optionally, the transition portion 73 is plate-shaped. It is convenient to connect the first connection portion 71 and the second connection portion 72 and stabilize the structure of the connection member 7.
In some embodiments, as shown in fig. 3, the heat dissipation member 3 includes: a first portion 31 provided directly below the fixed plate 20; a second portion 32 connected to the first portion 31 and provided obliquely below the fixed plate 20; wherein the second portion 32 is flexibly connected to the second connection 72. The first portion 31 is directly below the fixing plate 20 and is connected to a heat generating component. The second portion 32 is obliquely below the fixing plate 20, and the second portion 32 facilitates flexible connection with the second connecting portion 72 and contributes to the stability of the heat discharging member 3.
In some embodiments, as shown in fig. 4, the first portion 31 is provided with a first abutment 310 formed extending toward the fixation plate 20. When the first portion 31 is inclined toward the fixing plate 20, the first abutting portion 310 can abut against the surface of the fixing plate 20, and the first portion 31 is restricted from being continuously inclined toward the fixing plate 20, thereby preventing the heat dissipation member 3 from being inclined as a whole. Optionally, the first abutting portion 310 is a vertical plate disposed vertically. The riser abuts the fixed plate 20 limiting the tilting of the first portion 31 towards the fixed plate 20. Optionally, the first abutting portion 310 is plural. The first abutting portions 310 cooperate to keep the heat dissipation member 3 stable and prevent the heat dissipation member from tilting. Optionally, there is a gap between the first abutment 310 and the fixing plate 20. The first abutting part 310 is prevented from abutting too tightly against the fixing plate 20 to form a compression, which results in damage to the fixing plate 20.
In some embodiments, the edge of the fixing plate 20 is provided with a second abutting portion 203 formed by bending toward the first portion 31. The edge of the fixing plate 20 forms the second abutting portion 203, which cooperates with the first abutting portion 310 to have a larger limit range for the heat dissipation member 3, so as to prevent the first portion 31 of the heat dissipation member 3 from being seriously upwarped to cause the heat dissipation member 3 to incline, and avoid concentrating the abutting acting force on the first abutting portion 310 to cause the first abutting portion 310 to be easily aged and damaged.
In some embodiments, the housing 1 is provided with a beam 4 inside, and the surface of the beam 4 is provided with a convex part 40; the heat dissipation member 3 is placed on the surface of the cross beam 4, and is provided with a through hole into which the protruding portion 40 extends.
The heat radiation member 3 is configured to radiate heat from a heat generating component. The heat dissipation member 3 is placed on the cross member 4, and the cross member 4 can provide support for the heat dissipation member 3. The projection 40 on the surface of the beam 4 extends into the through hole of the heat dissipation member 3, so that the relative displacement between the beam 4 and the heat dissipation member 3 in the transverse direction can be limited, and the beam 4 and the heat dissipation member 3 can move relatively in the longitudinal direction. Thus, the heat dissipation member 3 is disposed in the casing 1 in a flexible connection manner, and when the outdoor unit vibrates and drives the beam 4 to vibrate, the beam 4 can move to a certain extent relative to the heat dissipation member 3, thereby preventing the heat dissipation member 3 from generating a hard acting force and preventing the heat dissipation member 3 from being deformed and damaged after being stressed.

Alternatively, the cross member 4 is disposed obliquely above the fan of the outdoor unit of the air conditioner. In this way, the cross beam 4 can avoid the position of the fan bracket 2 of the outdoor unit of the air conditioner. The heat dissipation member 3 is placed at a position away from the heat generating component, which is advantageous for heat dissipation of the heat generating component. Optionally, the outdoor unit of the air conditioner further includes an electric control box 5, the opposite beam 4 is disposed on the other side of the fan, and the heat dissipation member 3 is connected to the electric control box 5.
