Description

Technical Field

[0001] The invention belongs to the technical field of ring network boxes, and in particular relates to a ring network box and a heat dissipation device thereof. Background Art

[0002] Since the position of the heat dissipation air inlet channel of the existing ring network box is fixed, the size of the heat dissipation air inlet channel is also fixed. This can easily lead to dust accumulation at the heat dissipation air inlet position at an accelerated rate after long-term use, thereby affecting the heat dissipation effect. In addition, the heat dissipation air inlet channel of the existing ring network box usually needs to be cleaned manually, which is not only troublesome, but also requires regular and timely cleaning. In addition, because the heat dissipation air inlet channel encounters airflow impact when taking in air, this will cause stress deformation of the heat dissipation hole position, thereby affecting the heat dissipation effect.

[0013] Furthermore, the telescopic rod comprises a first telescopic rod section and a second telescopic rod section which are slidably connected;

[0014] A flow channel is formed on the first section of the telescopic rod, a liquid cavity connected with the flow channel is formed on the second section of the telescopic rod, and a compression spring is arranged in the liquid cavity.

[0015] Furthermore, the liquid chambers of two corresponding adjacent telescopic rods are connected through the flow channel, so as to connect the liquid chambers of the corresponding multiple telescopic rods in series.

[0016] Furthermore, the heat dissipation assembly also includes a liquid filling pump, which is fixedly connected to the top of the shell, and the liquid filling pump is connected to the flow channel of the corresponding telescopic rod located at the top through a hose.

[0027] The present invention provides a first rigid paddle and a second rigid paddle on the heat dissipation filter that can move up and down relative to the housing, and the first rigid paddle and the second rigid paddle are alternately arranged along the length direction of the heat dissipation filter to divide the heat dissipation filter into a plurality of heat dissipation areas, and the length of the heat dissipation filter is set to allow at least part of the heat dissipation area to bulge outward, and the first shielding plate and the second shielding plate are alternately connected to the upper ends of the plurality of heat dissipation areas through their upper side edges, and two adjacent first rigid paddles are connected by a first telescopic rod, and two adjacent second rigid paddles are connected by a second telescopic rod. Based on this structural setting, on the one hand, the position of the actual air intake channel in the heat dissipation channel can be changed during use, and the speed of the air intake channel being blocked can be slowed down, thereby effectively improving the heat dissipation efficiency. On the other hand, by setting the overall shape of the heat dissipation filter to be wavy, so that the air intake channel is wavy as a whole, and by setting the shielding structure of the inner layer net and the outer layer plate, the opening and closing of the air intake channel can be realized. In addition, since the inner layer of the net is an elastic pocket-shaped structure when it is bulged, it can make itself vibrate when the airflow passes through.

[0028] The present invention can also control the length of the telescopic rod through a liquid filling pump, thereby controlling the degree of bulge of the heat dissipation area, and then controlling the degree of opening of the baffle. Based on this, the air intake channel can be directly closed to achieve sealing and waterproofing in extreme weather.

[0029] The present invention also forms two layers of variable air intake channels by arranging two heat dissipation components at intervals along the air intake direction. By coordinating the opening and closing of the baffle plate, the air intake channel can be changed and the mesh surfaces of the two inner and outer heat dissipation filters can be better self-cleaned.

[0030] The present invention effectively realizes multiple filtering and can also effectively assist self-cleaning by setting the aperture of the filter hole of the heat dissipation filter of the heat dissipation component located on the outside to be larger than the aperture of the filter hole of the heat dissipation filter of the heat dissipation component located on the inside.

[0031] In addition, the present invention can also control the length of the first telescopic rod and the second telescopic rod to change back and forth according to the external ambient temperature, and can control the length change amount and the reciprocating alternation frequency according to the external ambient temperature. Specifically, the higher the external ambient temperature, the greater the length change amount of the first telescopic rod and the second telescopic rod and the higher the reciprocating alternation frequency, so that the change amount and change speed of the protrusion degree of the heat dissipation area are greater, so that the change amount and change speed of the opening degree of the shielding plate are also increased, thereby further improving the heat dissipation effect; conversely, the lower the external ambient temperature, the smaller the length change amount of the first telescopic rod and the second telescopic rod and the reciprocating alternation frequency are also lower, so that the change amount and change speed of the protrusion degree of the heat dissipation area are smaller, so that the change amount and change speed of the opening degree of the shielding plate are also smaller, so as to take into account energy efficiency at the same time.

[0042] First, if Figure 1As shown, the ring network box 100 in this embodiment is provided with a plurality of rectangular heat dissipation channels, the heat dissipation channels are long strip-shaped through-hole structures, and the heat dissipation device 200 is arranged in the heat dissipation channel, that is, it is fixed through, and the external air can enter the ring network box 100 only through the heat dissipation device 200. Figure 1 In the orientation shown in , eight heat dissipation channels are arranged on the front side of the ring network box 100, two heat dissipation channels are arranged on the left and right sides respectively, and twelve heat dissipation devices 200 are arranged in the twelve heat dissipation channels respectively. Of course, the present invention does not limit the specific shape of the ring network box 100 and the specific shape, number and distribution of the heat dissipation channels. Those skilled in the art can set them according to actual use requirements, as long as the heat dissipation channels are provided with heat dissipation devices 200.

[0043] Specifically, Figures 2 to 4As shown, the heat dissipation device 200 of the present invention includes a housing 2001 and a heat dissipation assembly, and the heat dissipation assembly includes a heat dissipation filter 201, a first rigid paddle 2014, a second rigid paddle 2015, a first shielding plate 2012, a second shielding plate 2013, a first telescopic rod 202, a second telescopic rod 203, a first driving member 206, and a second driving member 207. The housing 2001 is a rectangular parallelepiped frame structure, and the outer shape of the housing 2001 matches the shape of the inner side wall of the heat dissipation channel. The housing 2001 can be embedded in the heat dissipation channel and connected to the inner wall of the heat dissipation channel to support the heat dissipation assembly. The main body of the heat dissipation filter 201 is a flexible structure with filter holes arranged thereon, and the upper and lower ends of the heat dissipation filter 201 are fixedly connected to the two ends of the housing 2001. The number of the first rigid paddle 2014 and the second rigid paddle 2015 are both multiple, and the arrangement of the multiple first rigid paddles 2014 and the second rigid paddle 2015 is as follows: the first rigid paddle 2014 and the second rigid paddle 2015 can move up and down relative to the housing 2001, that is, the first rigid paddle 2014 and the second rigid paddle 2015 can move up and down in the space between two adjacent paddles, that is, each paddle can be displaced along the length direction of the heat dissipation filter 201, and the two are alternately arranged along the length direction of the heat dissipation filter 201 to divide the heat dissipation filter 201 into multiple heat dissipation areas. In this embodiment, the top paddle is The first rigid paddle 2014 is the second rigid paddle 2015, the third paddle is the first rigid paddle 2014, and the two adjacent paddles are spaced a certain distance apart to allow them to move up and down, and so on, they are alternately arranged along the length direction (i.e., the up and down direction) of the heat dissipation filter 201. The length of the heat dissipation filter 201 is set to allow at least part of the heat dissipation area to bulge outward, that is, the length of the heat dissipation filter 201 is greater than the height distance between the two paddles at the upper and lower ends, and the heat dissipation filter 201 will not be in a straight state, but will have a bulge, which is bounded by the paddles, so that at least part of the heat dissipation area between the two adjacent paddles can bulge outward. Taking the position of the first rigid paddle 2014 located at the top as the boundary, the part of the heat dissipation filter 201 located above it is made of non-deformable hard material for easy installation and fixation. The total number of the first shielding plates 2012 and the second shielding plates 2013 is equal to the number of the heat dissipation regions, and the first shielding plates 2012 and the second shielding plates 2013 are alternately connected to the upper ends of the plurality of heat dissipation regions through their upper side edges.Two adjacent first rigid paddles 2014 are connected through the first telescopic rod 202, that is, the upper end of the first telescopic rod 202 is fixedly connected to one first rigid paddle 2014, and the lower end thereof is fixedly connected to another adjacent first rigid paddle 2014. The first telescopic rod 202 can adjust the distance between the two adjacent first rigid paddles 2014 by changing the length by telescoping; two adjacent second rigid paddles 2015 are connected through the second telescopic rod 203, that is, the upper end of the second telescopic rod 203 is fixedly connected to one second rigid paddle 2015, and the lower end thereof is fixedly connected to another adjacent second rigid paddle 2015. The second telescopic rod 203 can adjust the distance between the two adjacent second rigid paddles 2015 by changing the length by telescoping. In addition, the first driving member 206 is configured to be able to push the plurality of first rigid paddles 2014 to move relative to the housing 2001, and the second driving member 207 is configured to be able to push the plurality of second rigid paddles 2015 to move relative to the housing 2001. It should be noted that although the first driving member 206 in the preferred embodiment is a first electric cylinder and the second driving member 207 is a second electric cylinder, this is not restrictive. For example, the driving member can also be a linear motor or a cylinder structure, which is not restrictive as long as it can push the rigid paddle to move relative to the housing 2001.

[0044] A plurality of first rigid paddles 2014 are fixedly connected to the heat dissipation filter 201. When the first rigid paddles 2014 move up and down relative to the outer shell 2001, they can drive the connection parts thereof to move together, so as to change the degree of protrusion of the heat dissipation area. A plurality of second rigid paddles 2015 are also fixedly connected to the heat dissipation filter 201. When the second rigid paddles 2015 move up and down relative to the outer shell 2001, they can drive the connection parts thereof to move together, so as to change the degree of protrusion of the heat dissipation area.

[0045] A shielding plate is correspondingly arranged in each heat dissipation area, and the first shielding plates 2012 and the second shielding plates 2013 are arranged alternately. Specifically, the shape of the baffle plate matches the shape of the heat dissipation area. By fixing the upper edge of the baffle plate to the upper end of the heat dissipation area, when the corresponding heat dissipation area bulges outward, the lower part of the baffle plate can be tilted outward to be pushed open, thereby opening the air intake channel; and when the heat dissipation area is in a flat state, the baffle plate is in a naturally drooping state, thereby shielding the surface of the heat dissipation area, thereby closing the air intake channel; the degree of bulge of the heat dissipation area can be controlled by controlling the length of the telescopic rod. Specifically, the height distance between two adjacent identical paddles can be controlled by controlling the length of the telescopic rod, while the length of the heat dissipation filter 201 located between two adjacent identical paddles is unchanged. When the telescopic rod is shortened, the distance between the two adjacent identical paddles becomes smaller, and the degree of bulge becomes larger. When the telescopic rod is lengthened, the distance between the two adjacent identical paddles becomes larger, and the degree of bulge becomes smaller, that is, the curvature of the inner arc surface 2011 formed by the bulge is controlled. By controlling the degree of bulge of the heat dissipation area, the degree of inclination of the baffle plate can be controlled, thereby controlling the degree to which the baffle plate shields the air intake channel, thereby controlling the degree of opening of the air intake channel.

[0046] Further integration Figure 4 and Figure 5Taking the structure of the first telescopic rod 202 as an example, the first telescopic rod 202 includes a first telescopic rod section 2031 and a second telescopic rod section 2033 that are slidably connected. The upper end of the first telescopic rod section 2031 of the first telescopic rod 202 is fixedly connected to the lower surface of the first rigid paddle 2014 located above the corresponding position, and the lower end of the second telescopic rod section 2033 of the first telescopic rod 202 is fixedly connected to the upper surface of the first rigid paddle 2014 located below the corresponding position. The first telescopic rod section 2031 can be sleeved on the second telescopic rod section 2033. 033 to achieve sliding connection, a flow channel 2032 is formed on the first section 2031 of the telescopic rod, a liquid chamber 2035 that can communicate with the flow channel 2032 is formed on the second section 2033 of the telescopic rod, and a compression spring 2034 is arranged in the liquid chamber 2035, the upper end of the compression spring 2034 is fixedly connected to the lower end of the first section 2031 of the telescopic rod, and the lower end of the compression spring 2034 is fixedly connected to the first rigid paddle 2014 located at the corresponding lower part, at this time, the upper surface of the first rigid paddle 2014 seals the lower end of the liquid chamber 2035. In this embodiment, except for the second rigid paddle 2015 located at the lowest part, the other second rigid paddles 2015 are all provided with a first through hole for the first telescopic rod 202 to pass through; based on the setting of the first through hole, the liquid chambers 2035 of two adjacent first telescopic rods 202 are connected through the flow channel 2032, so that all the liquid chambers 2035 of the corresponding multiple first telescopic rods 202 are connected in series. In addition, the heat dissipation assembly further includes a first liquid filling pump 204, which is fixedly connected to the top of the housing 2001, and the first liquid filling pump 204 is connected to the flow channel 2032 of the first telescopic rod 202 located at the top through a first hose 2041, and the first hose 2041 is passed through a through hole provided on the first rigid paddle 2014 located at the top. The first liquid filling pump 204 can control the telescopic length of all the first telescopic rods 202, and thus control the degree of bulging of the heat dissipation area corresponding to the first shielding plate 2012. By controlling the length of the first telescopic rod 202, the height distance between two adjacent first rigid paddles 2014 can be controlled, and the length of the heat dissipation filter 201 between the two adjacent first rigid paddles 2014 is unchanged. Based on this, when the first telescopic rod 202 is shortened, the distance between the two adjacent first rigid paddles 2014 becomes smaller, and the degree of bulging becomes greater. When the first telescopic rod 202 is lengthened, the distance between the corresponding two first rigid paddles 2014 becomes larger, and the degree of bulging becomes smaller.

[0047] It can be understood that the specific structure of the second telescopic rod 203 is the same as that of the first telescopic rod 202, which will not be repeated here; and the setting method of the second telescopic rod 203 is also similar to that of the first telescopic rod 202. Specifically, the upper end of the telescopic rod first section 2031 of the second telescopic rod 203 is fixedly connected to the lower surface of the second rigid paddle 2015 located at the corresponding upper part, and the lower end of the telescopic rod second section 2033 of the second telescopic rod 203 is fixedly connected to the upper surface of the second rigid paddle 2015 located at the corresponding lower part. Except for the first rigid paddle 2014 located at the bottom, the remaining first rigid paddles 2014 are all provided with second through holes for the second telescopic rod 203 to pass through; based on the setting of the second through holes, the liquid chambers 2035 of two adjacent second telescopic rods 203 are connected through the flow channel 2032, so that the liquid chambers 2035 of the corresponding multiple second telescopic rods 203 are all connected in series. The second filling pump 205 is also fixedly connected to the top of the housing 2001, and the second filling pump 205 is connected to the flow channel 2032 of the second telescopic rod 203 located at the top through the second hose 2051, and the second hose 2051 is passed through the through hole set on the second rigid paddle 2015 located at the top. In addition, the second filling pump 205 can control the telescopic length of all the second telescopic rods 203, thereby controlling the degree of bulging of the heat dissipation area corresponding to the second shielding plate 2013. By controlling the length of the second telescopic rod 203, the height distance between two adjacent second rigid paddles 2015 can be controlled, and the length of the heat dissipation filter 201 located between the two adjacent second rigid paddles 2015 is unchanged. Based on this, when the second telescopic rod 203 is shortened, the distance between the two adjacent second rigid paddles 2015 becomes smaller, and the degree of bulging becomes larger. When the second telescopic rod 203 is lengthened, the distance between the corresponding two second rigid paddles 2015 becomes larger, and the degree of bulging becomes smaller.

[0048] Next Read Figures 2 to 4 In this preferred embodiment, the number of heat dissipation components is two, and the two heat dissipation components are arranged on the housing 2001 at intervals along the wind direction. The aperture of the filter hole of the heat dissipation filter 201 of the heat dissipation component located on the outside is larger than the aperture of the filter hole of the heat dissipation filter 201 of the heat dissipation component located on the inside. Of course, the specific size, number and distribution of the filter holes are not restrictive. In addition, Figure 2 and Figure 3 As shown in FIG. 1 , the raised portions of the heat dissipation filters 201 of the two heat dissipation components are raised outwardly in a direction away from each other.

[0049] Continue reading Figure 4The first driving member 206 is fixedly connected to the bottom of the housing 2001, and the driving end of the first driving member 206 is connected to the side of the first rigid paddle 2014 located at the bottom, so as to push the first rigid paddle 2014 located at the bottom to push all the first rigid paddles 2014 located above it, thereby causing the heat dissipation filter 201 to vibrate; the second driving member 207 is fixedly connected to the bottom of the housing 2001, and the driving end of the second driving member 207 is connected to the side of the second rigid paddle 2015 located at the bottom, so as to push the second rigid paddle 2015 located at the bottom to push all the second rigid paddles 2015 located above it, thereby causing the heat dissipation filter 201 to vibrate. In one application scenario, the first driving member 206 and the second driving member 207 are controlled to perform reciprocating and asynchronous telescopic movements with a small amplitude, so that the heat dissipation filters 201 of the inner and outer heat dissipation components can be controlled to continuously shake; in another application scenario, the first driving member 206 and the second driving member 207 are controlled to perform reciprocating and asynchronous telescopic movements with a large amplitude, so that the positions of the bulging areas and the flat areas on the corresponding heat dissipation filters 201 can be controlled to continuously switch.

[0050] In addition, the present invention also provides a ring network box 100, including a controller and the heat dissipation device 200 described in the above embodiment, the controller is configured to control the first driving member 206 and the second driving member 207 to push the first rigid paddle 2014 and the second rigid paddle 2015 to move up and down reciprocatingly and alternately, and the controller is also configured to control the length of the first telescopic rod 202 and the second telescopic rod 203 to change reciprocally and alternately according to the external ambient temperature, and to control the length change amount and reciprocating alternation frequency according to the external ambient temperature. Specifically, during the reciprocating change of the length of the first telescopic rod 202 and the second telescopic rod 203, the distance between the two adjacent first rigid paddles 2014 and the second rigid paddles 2015 will be continuously changed, thereby driving the corresponding heat dissipation area to continuously swell and flatten. During this reciprocating change process, the positions of the bulging area and the flat area on the heat dissipation filter 201 will be continuously switched within a certain time difference. Within this time difference, the length of the first telescopic rod 202 and the second telescopic rod 203 will change reciprocatingly. The reciprocating change process will drive the change in the bulging degree of the heat dissipation area, and then drive the opening degree of the first baffle plate 2012 and the second baffle plate 2013, thereby affecting the heat dissipation effect. For example, in the process of the first telescopic rod 202 becoming longer, a certain heat dissipation area is gradually straightened, that is, the bulging degree is gradually reduced, and at this time, the inclination angle of the first shielding plate 2012 corresponding to the area will also be continuously reduced, that is, the opening degree is gradually reduced, and the first shielding plate 2012 gradually falls; in the process of the first telescopic rod 202 becoming shorter, the heat dissipation area is gradually bulged, that is, the bulging degree is gradually increased, and at this time, the inclination angle of the corresponding first shielding plate 2012 will also be continuously reduced, that is, the opening degree is gradually increased, and the first shielding plate 2012 is gradually lifted, so that the heat dissipation area The domain continuously switches between a bulging state and a flat state, and the bulging degree also changes. During this process, the opening degree of the first baffle plate 2012 also changes continuously, presenting a state of reciprocating lifting and falling. The first baffle plate 2012 performs a reciprocating rotation motion with the connection between the first baffle plate 2012 and the heat dissipation filter 201 as the axis. This process is similar to the process of fanning a fan. By increasing the length change and the reciprocating alternating frequency, the fanning action of the first baffle plate 2012 can be accelerated, the fanning frequency can be increased, and the heat dissipation effect can be effectively improved.A further specific setting method is: the higher the external ambient temperature, the greater the change in the length of the first telescopic rod 202 and the second telescopic rod 203 and the higher the reciprocating alternating frequency, so that the change in the degree of protrusion of the heat dissipation area and the change speed are greater, so that the change in the degree of opening of the first baffle 2012 and the second baffle 2013 and the change speed are also increased, that is, the higher the fanning frequency, the further improved the heat dissipation effect; conversely, the lower the external ambient temperature, the smaller the change in the length of the first telescopic rod 202 and the second telescopic rod 203 and the reciprocating alternating frequency are also lower, so that the change in the degree of protrusion of the heat dissipation area and the change speed are reduced, so that the change in the degree of opening of the first baffle 2012 and the second baffle 2013 and the change speed are also reduced, so as to take into account energy efficiency at the same time.

[0051] Based on the above structural configuration, the heat dissipation device 200 of the present invention has the following four motion modes:

[0052] The first sports mode:

[0053] Under the condition that the lengths of the first telescopic rod 202 and the second telescopic rod 203 remain unchanged, the first driving member 206 and the second driving member 207 are controlled to reciprocate and asynchronously telescope with a first amplitude to control the vibration of the heat dissipation filter 201 of the inner and outer heat dissipation components. The first amplitude: does not change the position of the ventilation channel, and the telescopic amplitude is smaller than the width of the heat dissipation area.

[0054] Second sports mode:

[0055] Under the condition that the lengths of the first telescopic rod 202 and the second telescopic rod 203 remain unchanged, the first driving member 206 and the second driving member 207 are controlled to reciprocate and asynchronously telescope at a second amplitude, so as to control the continuous switching of the positions of the bulging area and the flat area on the corresponding heat dissipation filter 201. The second amplitude: the position of the ventilation channel is changed, and the telescopic amplitude is greater than the width of the heat dissipation area.

[0056] The third sports mode:

[0057] The lengths of the first telescopic rod 202 and the second telescopic rod 203 are changed alternately according to the external ambient temperature, and the length change amount and the reciprocating alternation frequency can be controlled according to the external ambient temperature. The higher the external ambient temperature is, the greater the length change amount of the first telescopic rod 202 and the second telescopic rod 203 and the higher the reciprocating alternation frequency is, so that the change amount and the change speed of the bulge degree of the heat dissipation area are greater, so that the change amount and the change speed of the opening degree of the first baffle plate 2012 and the second baffle plate 2013 are also increased accordingly, that is, the higher the fanning frequency is; conversely, the lower the external ambient temperature is, the smaller the length change amount of the first telescopic rod 202 and the second telescopic rod 203 and the reciprocating alternation frequency is also lower, so that the change amount and the change speed of the bulge degree of the heat dissipation area become smaller, so that the change amount and the change speed of the opening degree of the first baffle plate 2012 and the second baffle plate 2013 are also smaller.

[0058] The fourth sports mode:

[0059] First, the heat dissipation component located on the inner side of the ring network box 100 is controlled to move according to the second movement mode, so that the dust in the interlayer between the heat dissipation filter 201 located on the inner side and the heat dissipation filter 201 located on the outer side can be blown out from the large filter holes of the heat dissipation filter 201 located on the outer side, and then the heat dissipation component located on the outer side of the ring network box 100 is controlled to move according to the second movement mode to achieve comprehensive self-cleaning.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
