Description

Technical Field

[0001] The present invention relates to the technical field of cabinet ventilation and heat dissipation, and more specifically, to a ventilation and heat dissipation device for an outdoor cabinet. Background Art

[0002] The main purpose of the ventilation and heat dissipation device for an outdoor cabinet is for heat dissipation requirements. A large amount of heat is generated during the operation of electronic devices installed in the outdoor cabinet. If this heat cannot be dissipated in time, it will cause the equipment to overheat, thereby affecting its performance and stability, and even causing hardware damage. The ventilation and heat dissipation device can effectively reduce the temperature inside the cabinet and ensure that the equipment operates within an appropriate temperature range.

[0003] In the existing published literature, the patent with the patent announcement number CN208285712U discloses an outdoor communication cabinet. This technology enables the cooling fans to be electrically connected to the temperature sensor and the battery respectively, the driving device to be electrically connected to the temperature sensor and the battery respectively, and the solar photovoltaic panel to be electrically connected to the battery. When there is no sunlight shining on the communication cabinet, the solar photovoltaic panel covers the heat dissipation holes, so that rainwater, dust, etc. will not enter the cabinet interior from the heat dissipation holes; when sunlight shines on the communication cabinet and causes the temperature to be too high, the temperature sensor outputs a start signal to the driving device and the cooling fans. The driving device drives the solar photovoltaic panel to move above the cabinet to shade the cabinet from sunlight. At this time, the cooling fans start to dissipate heat inside the cabinet, so that the temperature inside the cabinet is easily reduced. However, this technology has the following defects.

[0004] During the use of ventilation and heat dissipation inside the outdoor cabinet, due to a large amount of high temperature generated by the electronic devices inside the outdoor cabinet, and at the same time, there will be a problem of too high humidity inside the outdoor cabinet. These all require temperature sensors and humidity sensors to provide sensing data, so as to adjust the size of the ventilation and heat dissipation air inlet according to the high and low temperature and humidity. However, the equipment sensor components not only have a high cost but also consume a lot of energy for continuous sensing. At the same time, the maintenance cost of outdoor sensors is relatively high. Therefore, it is difficult to achieve adjustment without power energy and it is difficult to adjust the size of the ventilation and heat dissipation air inlet according to the two parameters of humidity and temperature. The ventilation and heat dissipation device of the outdoor cabinet has poor energy-saving and cost-reducing performance. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: A ventilation and heat dissipation device for an outdoor cabinet, including a heat dissipation cabinet and a heat dissipation plate. The heat dissipation plate is fixed on one side of the heat dissipation cabinet. A plurality of heat dissipation inclined holes are opened inside the heat dissipation plate, and a hydrophobic ventilation and heat dissipation self-adaptive adjustment mechanism is installed inside the heat dissipation inclined holes; the hydrophobic ventilation and heat dissipation self-adaptive adjustment mechanism includes a support bar installed inside the heat dissipation inclined holes. The top end of the support bar is fixedly connected to a hydrophobic bottom sheet. A hydrophobic middle sheet is fixedly connected to the top end of the hydrophobic bottom sheet, and a hydrophobic top sheet is fixedly installed at the top end of the hydrophobic middle sheet.

[0006] An air intake inclined plate is fixedly connected to the upper surface of the hydrophobic upper sheet. Both the hydrophobic bottom sheet and the hydrophobic middle sheet are slidably connected to the heat dissipation plate, and both the air intake inclined plate and the hydrophobic upper sheet are slidably connected to the heat dissipation plate. A flow guiding plate is fixedly connected to the bottom end of the air intake inclined plate, and a hydrophilic ventilation and heat dissipation adaptive adjustment mechanism is installed at the top end of the air intake inclined plate. The support strip is fixedly connected to the heat dissipation plate where the heat dissipation inclined hole is located. Both the hydrophobic bottom sheet and the hydrophobic middle sheet are made of graphene material, and both the hydrophobic upper sheet and the air intake inclined plate are made of graphene. The vertical cross-sectional shape of the flow guiding plate is arc-shaped, and a plurality of the flow guiding plates are arranged at equal intervals from top to bottom, and the outer wall of the flow guiding plate is a smooth surface.

[0007] Preferably, two rubber strips are fixedly connected to the bottom end of the flow guiding plate, a reinforcing strip is provided at the bottom end of the rubber strip, and both the two rubber strips are fixedly connected to the reinforcing strip; the reinforcing strip is fixedly connected to the heat dissipation plate. A support block is provided above the heat dissipation plate, and the support block is fixedly connected to the heat dissipation cabinet, and a heat dissipation cap is fixedly connected to the upper surface of the support block;

[0008] Two cabinet wire grooves are fixedly connected inside the heat dissipation cabinet, and two hole plates are fixedly arranged between the two cabinet wire grooves. A driving motor is fixedly installed at the top end of the inner wall of the heat dissipation cabinet, and a heat dissipation blade is fixedly connected to the output end of the driving motor; a cover door is hinged on the other side of the heat dissipation cabinet.

[0009] In this technical solution, when the temperature inside the heat dissipation cabinet exceeds 45 degrees Celsius and continues to rise, since the hydrophobic bottom sheet, the hydrophobic middle sheet, and the hydrophobic upper sheet inside the heat dissipation inclined hole are all made of graphene material, and the graphene material has a negative thermal expansion property, the hydrophobic upper sheet shrinks and deforms downward, and the air intake inclined plate and the hydrophobic bottom sheet shrink to drive the hydrophobic middle sheet to shrink downward, so that the hydrophobic upper sheet drives the air intake inclined plate to move downward. The gap between the air intake inclined plate and the top end of the inner wall of the heat dissipation inclined hole becomes larger, so that the heat dissipation air intake area increases, the ventilation air intake volume becomes larger, and a large amount of external cooling air quickly enters the inside of the heat dissipation cabinet, thereby realizing rapid heat exchange of the heat inside the heat dissipation cabinet. The hydrophobic bottom sheet, the hydrophobic middle sheet, and the hydrophobic upper sheet can be adaptively adjusted according to the temperature inside the heat dissipation cabinet.

[0010] Preferably, the hydrophilic ventilation and heat dissipation adaptive adjustment mechanism includes a connecting strip fixedly installed at the top end of the intake inclined plate; a positioning strip is fixedly connected to the upper surface of the connecting strip, a plurality of hydrophilic concave blocks are fixedly connected to the inner wall of the positioning strip, a hydrophilic side plate is fixedly connected to the lower inclined surface of the positioning strip, and a hydrophilic top plate is fixedly connected to the upper inclined surface of the positioning strip; one end of the positioning strip is fixedly connected to a socket block, a guide rod is slidably connected inside the socket block, a linkage block is fixedly installed at the top end of the guide rod, an elastic strip is fixedly connected to the side of the linkage block, and a reinforcing block is fixedly connected to the upper surface of the elastic strip, and the reinforcing block is fixedly connected to the heat dissipation plate. The plurality of hydrophilic concave blocks are arranged at equal intervals from left to right, and both the hydrophilic concave blocks and the hydrophilic side plate are made of sulfonated polyether ether ketone material.

[0011] In this technical solution, when the humidity inside the heat dissipation cabinet is relatively high and rapid dehumidification is required, the hydrophilic side plate, the hydrophilic concave blocks, and the hydrophilic top plate all absorb the water in the air inside the heat dissipation cabinet. After the hydrophilic side plate, the hydrophilic concave blocks, and the hydrophilic top plate absorb water, they expand, so that the volume increases and the weight increases. In this way, the positioning strip drives the connecting strip to move downward under the action of gravity, the socket block slides downward along the outer wall of the guide rod, the reinforcing block supports the elastic strip, and the elastic strip is softly connected with the linkage block. Ensure that the connecting strip can drive the intake inclined plate to move downward, and the intake inclined plate is affected by gravity, so that the gap between the intake inclined plate and the top end of the inner wall of the heat dissipation inclined hole becomes larger.

[0012] Preferably, a support and diversion assembly is provided above the diversion plate. The support and diversion assembly includes a guide plate arranged above the diversion plate; two arc-shaped plates are fixedly connected above the guide plate, an arc-shaped strip is fixedly connected between the two arc-shaped plates, and the heat dissipation plate is fixedly connected to the arc-shaped strip. A reinforcing plate is provided above the arc-shaped strip, and both the guide plate and the heat dissipation plate are fixedly connected to the reinforcing plate. The vertical cross-sectional shape of the guide plate is arc-shaped, and the two arc-shaped plates are symmetrically arranged with respect to the arc-shaped strip.

[0013] In this technical solution, the external cooling air quickly enters the gap between the top end of the inner wall of the heat dissipation inclined hole and the intake inclined plate along the guiding position between the diversion plate and the guide plate. The reinforcing plate supports the guide plate, and the arc-shaped plates support the guide plate, so that the guide plate can stably divert the external cooling air to the designated position quickly.

[0014] The technical effects and advantages of the present invention:

[0015] Through the hydrophobic ventilation and heat dissipation adaptive adjustment mechanism of the present invention, when the internal temperature of the heat dissipation cabinet exceeds 45 degrees Celsius, since the hydrophobic bottom sheet, hydrophobic middle sheet, and hydrophobic top sheet inside the heat dissipation inclined holes are all made of graphene material and have negative thermal expansion characteristics, the hydrophobic top sheet shrinks and deforms downward, the hydrophobic middle sheet shrinks and drives the hydrophobic top sheet to deform downward, the hydrophobic bottom sheet of the air intake inclined plate shrinks and drives the hydrophobic middle sheet to shrink downward, the hydrophobic top sheet drives the air intake inclined plate to move downward, the gap between the air intake inclined plate and the top end of the inner wall of the heat dissipation inclined hole becomes larger, the heat dissipation air intake area increases, and the ventilation air intake volume becomes larger. It can automatically adjust the size of the ventilation and heat dissipation air intake according to temperature parameters. Not only does it not require power energy adjustment, but also the maintenance cost is relatively low, greatly improving the energy conservation and cost reduction of the ventilation and heat dissipation device of the outdoor cabinet.

[0016] Through the hydrophilic ventilation and heat dissipation adaptive adjustment mechanism of the present invention, when the humidity inside the heat dissipation cabinet is relatively high and rapid dehumidification is required, the hydrophilic side plates, hydrophilic concave blocks, and hydrophilic top plates all absorb water bodies in the air inside the heat dissipation cabinet. After the hydrophilic side plates, hydrophilic concave blocks, and hydrophilic top plates absorb water, they expand, so the volume increases and the weight increases, ensuring that the connecting strip can drive the air intake inclined plate to move downward. Affected by gravity, the air intake inclined plate moves downward, and the gap between the air intake inclined plate and the top end of the inner wall of the heat dissipation inclined hole becomes larger. It can automatically adjust the size of the ventilation and heat dissipation air intake according to humidity parameters. Not only does it not require power energy adjustment, but also the maintenance cost is relatively low, greatly improving the energy conservation and cost reduction of the ventilation and heat dissipation device of the outdoor cabinet.

[0017] The present invention adopts a support and diversion assembly, so that the external cooling air quickly enters the gap between the top end of the inner wall of the heat dissipation inclined hole and the air intake inclined plate along the guiding position between the diversion plate and the guiding plate. The arc-shaped strip supports the two arc-shaped plates, the arc-shaped plates support the guiding plate, and the guiding plate can stably divert the external cooling air to the designated position quickly, improving the air gathering and heat dissipation ability and having a better heat dissipation effect.

[0018] Due to the mutual influence of the above multiple functions, first, the hydrophobic bottom sheet, hydrophobic middle sheet, and hydrophobic top sheet realize the high-temperature negative thermal expansion and contraction function, then the hydrophilic side plates, hydrophilic concave blocks, and hydrophilic top plates realize the hydrophilic weight function, and finally the guiding plate can stably divert the external cooling air to the designated position quickly. In summary, it can automatically adjust the size of the ventilation and heat dissipation air intake according to temperature and humidity parameters. Not only does it not require power energy adjustment, but also the maintenance cost is relatively low, greatly improving the energy conservation and cost reduction of the ventilation and heat dissipation device of the outdoor cabinet.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Such as Figure 1 - Figure 9A ventilation and heat dissipation device for an outdoor cabinet as shown. A hydrophobic ventilation and heat dissipation adaptive adjustment mechanism, a hydrophilic ventilation and heat dissipation adaptive adjustment mechanism, and a support and diversion assembly are provided on the ventilation and heat dissipation device of the outdoor cabinet. The settings of each mechanism and component can automatically adjust the size of the ventilation and heat dissipation air inlet according to temperature and humidity parameters. Not only does it not require power energy adjustment, but also the maintenance cost is relatively low, greatly improving the energy-saving and cost-reducing performance of the ventilation and heat dissipation device of the outdoor cabinet. The specific structural settings of each mechanism and component are as follows.

[0031] In this technical solution, as Figure 1 - Figure 4 shown, the heat dissipation plate 2 is fixed on one side of the heat dissipation cabinet 1. A plurality of heat dissipation inclined holes 3 are opened inside the heat dissipation plate 2, and a hydrophobic ventilation and heat dissipation adaptive adjustment mechanism is installed inside the heat dissipation inclined holes 3; the hydrophobic ventilation and heat dissipation adaptive adjustment mechanism includes a support bar 4 installed inside the heat dissipation inclined holes 3. The top end of the support bar 4 is fixedly connected to a hydrophobic bottom sheet 5. A hydrophobic middle sheet 6 is fixedly connected to the top end of the hydrophobic bottom sheet 5, and a hydrophobic upper sheet 7 is fixedly installed at the top end of the hydrophobic middle sheet 6.

[0032] The upper surface of the hydrophobic upper sheet 7 is fixedly connected to an intake air inclined plate 8. Both the hydrophobic bottom sheet 5 and the hydrophobic middle sheet 6 are slidably connected to the heat dissipation plate 2, and both the intake air inclined plate 8 and the hydrophobic upper sheet 7 are slidably connected to the heat dissipation plate 2. The bottom end of the intake air inclined plate 8 is fixedly connected to a diversion plate 9, and a hydrophilic ventilation and heat dissipation adaptive adjustment mechanism is installed at the top end of the intake air inclined plate 8. The support bar 4 is fixedly connected to the heat dissipation plate 2 to which the heat dissipation inclined holes 3 belong. Both the hydrophobic bottom sheet 5 and the hydrophobic middle sheet 6 are made of graphene material, and both the hydrophobic upper sheet 7 and the intake air inclined plate 8 are made of graphene. The vertical cross-sectional shape of the diversion plate 9 is arc-shaped. A plurality of diversion plates 9 are arranged at equal intervals from top to bottom, and the outer wall of the diversion plate 9 is a smooth surface.

[0033] In this technical solution, as Figure 1 - Figure 5 shown, two rubber strips 10 are fixedly connected to the bottom end of the diversion plate 9. A reinforcing strip 11 is provided at the bottom end of the rubber strips 10, and both rubber strips 10 are fixedly connected to the reinforcing strip 11; the reinforcing strip 11 is fixedly connected to the heat dissipation plate 2, so as to facilitate the diversion plate 9 to drive the top end of the rubber strips 10 to move downward. The heat dissipation plate 2 supports the reinforcing strip 11, the reinforcing strip 11 supports the rubber strips 10, and the diversion plate 9 and the rubber strips 10 are in soft connection.

[0034] Above the heat dissipation plate 2, there is a support block 12, and the support block 12 is fixedly connected to the heat dissipation cabinet 1. The upper surface of the support block 12 is fixedly connected with a heat dissipation cap 13; Inside the heat dissipation cabinet 1, two cabinet wire grooves 14 are fixedly connected. Between the two cabinet wire grooves 14, two hole plates 15 are fixedly arranged. At the top end of the inner wall of the heat dissipation cabinet 1, a driving motor 16 is fixedly installed. The output end of the driving motor 16 is fixedly connected with a heat dissipation blade 17; On the other side of the heat dissipation cabinet 1, a cover door 18 is hinged. So that after the cover door 18 is opened, the electronic device can be installed on the hole plate 15, and the wire harness of the electronic device is installed inside the cabinet wire groove 14. When the electronic device operates inside the heat dissipation cabinet 1, high-temperature heat will be generated. The driving motor 16 drives the heat dissipation blade 17 to rotate, and the hot air is discharged into the heat dissipation cap 13 along the heat dissipation cabinet 1 and diffuses outwards from the heat dissipation cap 13. The support block 12 provides a stable support force for the heat dissipation cap 13.

[0035] In this technical solution, as Figure 6 - Figure 8 shown, the hydrophilic ventilation heat dissipation adaptive adjustment mechanism includes a connecting strip 19 fixedly installed at the top end of the intake inclined plate 8; On the upper surface of the connecting strip 19, a positioning strip 20 is fixedly connected. Inside the inner wall of the positioning strip 20, a plurality of hydrophilic concave blocks 21 are fixedly connected. The lower inclined surface of the positioning strip 20 is fixedly connected with a hydrophilic side plate 22, and the upper inclined surface of the positioning strip 20 is fixedly connected with a hydrophilic top plate 23.

[0036] One end of the positioning strip 20 is fixedly connected with a socket block 24. Inside the socket block 24, a guide rod 25 is slidably connected. The top end of the guide rod 25 is fixedly installed with a linkage block 26. The side part of the linkage block 26 is fixedly connected with an elastic strip 27, and on the upper surface of the elastic strip 27, a reinforcement block 28 is fixedly connected. The reinforcement block 28 is fixedly connected to the heat dissipation plate 2. The plurality of hydrophilic concave blocks 21 are arranged at equal intervals from left to right. Both the hydrophilic concave blocks 21 and the hydrophilic side plates 22 are made of sulfonated polyether ether ketone material.

[0037] In this technical solution, as Figure 9 shown, above the guide plate 9, there is a support and guide assembly. The support and guide assembly includes a guide plate 29 arranged above the guide plate 9; Above the guide plate 29, two arc plates 31 are fixedly connected. Between the two arc plates 31, an arc bar 30 is fixedly connected, and the heat dissipation plate 2 is fixedly connected to the arc bar 30. Above the arc bar 30, there is a reinforcement plate 32. Both the guide plate 29 and the heat dissipation plate 2 are fixedly connected to the reinforcement plate 32. The vertical cross-sectional shape of the guide plate 29 is circular arc-shaped, and the two arc plates 31 are symmetrically arranged with respect to the arc bar 30.

[0038] The working principle of the ventilation and heat dissipation device for the outdoor cabinet of the present invention is as follows:

[0039] Step 1: When installing and using, after opening the cover door 18, install the electronic device on the hole plate 15, and install the wire harness of the electronic device inside the cabinet wire groove 14. Then close the cover door 18, and the cover door 18 is closed with the heat dissipation cabinet 1. When the electronic device operates inside the heat dissipation cabinet 1, high-temperature heat will be generated. By starting the drive motor 16, the drive motor 16 drives the heat dissipation blades 17 to rotate, and the heat dissipation blades 17 cause the external cooling air to enter the heat dissipation cabinet 1 along the gap between the intake inclined plate 8 and the top inner wall of the heat dissipation inclined hole 3. After heat exchange inside the heat dissipation cabinet 1, the hot air is discharged into the heat dissipation cap 13 along the heat dissipation cabinet 1 and diffused outwards by the heat dissipation cap 13. Moreover, the support block 12 of the heat dissipation cabinet 1 provides a stable support force for the heat dissipation cap 13.

[0040] Step 2: During hydrophobic ventilation heat dissipation adaptive adjustment, when the temperature inside the heat dissipation cabinet 1 exceeds 45 degrees Celsius and continues to rise, since the hydrophobic bottom sheet 5, the hydrophobic middle sheet 6, and the hydrophobic top sheet 7 inside the heat dissipation inclined hole 3 are all made of graphene material, and the graphene material has a negative thermal expansion property, it shrinks as the temperature rises. At the same time, the support bar 4 supports the hydrophobic bottom sheet 5 to increase the stability of the hydrophobic bottom sheet 5. In this way, the hydrophobic top sheet 7 shrinks and deforms downward, the hydrophobic middle sheet 6 shrinks and drives the hydrophobic top sheet 7 to deform downward, and the intake inclined plate 8 and the hydrophobic bottom sheet 5 shrink and drive the hydrophobic middle sheet 6 to shrink downward. In this way, the hydrophobic top sheet 7 drives the intake inclined plate 8 to move downward, and the guide plate 9 drives the top end of the rubber strip 10 to move downward. At the same time, the heat dissipation plate 2 supports the reinforcement bar 11, and the reinforcement bar 11 supports the rubber strip 10 to provide a fixed support force for the bottom end of the rubber strip 10. In this way, the gap between the intake inclined plate 8 and the top inner wall of the heat dissipation inclined hole 3 becomes larger, so the heat dissipation intake area increases, the ventilation intake volume becomes larger, and a large amount of external cooling air quickly enters the heat dissipation cabinet 1, thereby quickly exchanging heat with the heat inside the heat dissipation cabinet 1. The hydrophobic bottom sheet 5, the hydrophobic middle sheet 6, and the hydrophobic top sheet 7 can be adaptively adjusted according to the temperature inside the heat dissipation cabinet 1, so that the gap between the intake inclined plate 8 and the top inner wall of the heat dissipation inclined hole 3 is automatically adjusted to increase at high temperatures.

[0041] Step 3: During hydrophilic ventilation heat dissipation adaptive adjustment, when the humidity inside the heat dissipation cabinet 1 is relatively high and rapid dehumidification is required, the hydrophilic top plate 23 is supported by the positioning strip 20. The positioning strip 20 supports multiple hydrophilic concave blocks 21 at the same time, and the positioning strip 20 supports the hydrophilic side plate 22. In this way, the hydrophilic side plate 22, the hydrophilic concave blocks 21, and the hydrophilic top plate 23 all absorb the water in the air inside the heat dissipation cabinet 1. Since the hydrophilic side plate 22, the hydrophilic concave blocks 21, and the hydrophilic top plate 23 are all hydrophilic materials. Therefore, after the hydrophilic side plate 22, the hydrophilic concave blocks 21, and the hydrophilic top plate 23 absorb water, they expand, so the volume increases and the weight increases.

[0042] In this way, the positioning bar 20 drives the connecting bar 19 to move downward under the action of gravity. The connecting bar 19 drives the socket block 24 to move downward. The socket block 24 slides downward along the outer wall of the guide rod 25. And the heat dissipation plate 2 supports the reinforcement block 28, the reinforcement block 28 supports the elastic strip 27, and the elastic strip 27 is softly connected to the linkage block 26. This ensures that the connecting bar 19 can drive the intake inclined plate 8 to move downward. Affected by gravity, the intake inclined plate 8 causes the gap between the intake inclined plate 8 and the top end of the inner wall of the heat dissipation inclined hole 3 to become larger. As a result, a large amount of external cooling air enters the inside of the heat dissipation cabinet 1, cooling and dissipating heat inside the heat dissipation cabinet 1, and at the same time dehumidifying the inside of the heat dissipation cabinet 1. In this way, according to the humidity inside the heat dissipation cabinet 1, the hydrophilic side plates 22, the hydrophilic top plate 23, and the hydrophilic concave blocks 21 can achieve automatic weight adjustment, so that the ventilation and heat dissipation gap between the intake inclined plate 8 and the heat dissipation inclined hole 3 can be adaptively adjusted.

[0043] Step 4: When supporting, guiding and dissipating heat, the external cooling air quickly enters the gap between the top end of the inner wall of the heat dissipation inclined hole 3 and the intake inclined plate 8 along the guiding position between the guiding plate 9 and the guide plate 29. At the same time, the heat dissipation plate 2 supports the reinforcement plate 32, the reinforcement plate 32 supports the guide plate 29, and the arc bar 30 supports the two arc plates 31. The arc plates 31 support the guide plate 29. In this way, the guide plate 29 can stably guide the external cooling air to the specified position quickly, realizing positioning ventilation and heat dissipation and improving the ventilation and heat dissipation effect.
