Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation devices, and particularly to a high-temperature heat dissipation device for large-size outdoor advertising screens. Background Art

[0002] There are a large number of scenarios in production and life for storing, transporting, and applying electric energy, such as in places like electric vehicle charging piles; the electric vehicle owners served by the charging pile sites belong to high-net-worth and high-staying populations; in order to enhance the value of the place, advertisements are projected through advertising screens in such places; however, in order to ensure the normal use of the advertising screen and the safety of the place, a structure needs to be set up to keep the billboard fully cooled.

[0003] For example, Chinese Patent No. CN117621883A discloses a floor-standing charging pile with an advertising screen. An advertising screen is provided on the charging pile, and a heat dissipation device is provided between the advertising screen and the charging pile to dissipate heat from the advertising screen by means of cold air flow through the heat dissipation device.

[0004] However, large-size advertising screens are usually composed of multiple modular LED advertising screens; during use, if a certain advertising screen module operates abnormally and causes local high temperature, and if not discovered in time, it is likely to cause damage to the advertising screen and even affect the safety of the place.

[0005] Based on this, the present invention designs a high-temperature heat dissipation device for large-size outdoor advertising screens to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned drawbacks of the prior art, the present invention provides a high-temperature heat dissipation device for large-size outdoor advertising screens.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A high-temperature heat dissipation device for large-size outdoor advertising screens, comprising a support frame, a positioning and monitoring mechanism, a cooling and diversion box, a heat dissipation mechanism, and an adjustment mechanism; On the rear side of the support frame, multiple groups of advertising screens are evenly and fixedly installed in a rectangular array; a cooling and diversion box is fixedly installed on the front side of the support frame; a positioning and monitoring mechanism for detecting the local temperature of the advertising screen is installed between the advertising screen and the cooling and diversion box; a heat dissipation mechanism is installed inside the cooling and diversion box, and an adjustment mechanism is installed on the front side of the cooling and diversion box; The positioning and monitoring mechanism includes multiple groups of temperature sensing modules and a monitoring module. Multiple groups of temperature sensing modules that deform with temperature change are installed at equal intervals on the front side of the advertising screen, and a monitoring module for monitoring the temperature sensing modules is installed on the side of the support frame; The adjusting mechanism includes a rotating filter cylinder, an adjusting module, and a ventilation module. The rotating filter cylinder is rotatably installed on the front side of the cooling diversion box. A plurality of air filtering holes are evenly arranged at equal intervals on one side of the rotating filter cylinder. Both ends of the rotating filter cylinder communicate with the cooling diversion box. An adjusting module for adjusting the rotating filter cylinder is installed on the cooling diversion box. A ventilation module is installed on the cooling diversion box.

[0008] Furthermore, the temperature sensing module includes a heat conducting plate, a copper plate, and a thin-walled metal bellows. The heat conducting plate is fixedly installed on the front side of the advertising screen. The copper plate is fixedly installed in the middle of the heat conducting plate. A plurality of groups of closed thin-walled metal bellows are symmetrically and fixedly installed on the copper plate.

[0009] Furthermore, the monitoring module includes a laser sensor. A plurality of laser sensors for monitoring the thin-walled metal bellows are fixedly installed on the side of the support frame. Each laser sensor monitors multiple groups of thin-walled metal bellows in the same row.

[0010] Furthermore, a reflux chamber, a cooling chamber, a vortex chamber, and a confluence chamber are sequentially arranged in the cooling diversion box from front to back. A heat dissipation chamber is formed between the advertising screen and the cooling diversion box. A diversion channel is arranged in the cooling diversion box to connect the vortex chamber, the heat dissipation chamber, the confluence chamber, the reflux chamber, the rotating filter cylinder, and the cooling chamber in sequence.

[0011] Furthermore, the diversion channel includes cooling diversion pipes and heat dissipation diversion pipes. A plurality of groups of cooling diversion pipes for connecting the vortex chamber and the heat dissipation chamber are evenly and fixedly arranged at equal intervals between the vortex chamber and the heat dissipation chamber. A plurality of groups of heat dissipation holes for connecting the heat dissipation chamber and the confluence chamber are evenly opened at equal intervals on the rear side of the cooling diversion box. A plurality of heat dissipation diversion pipes for connecting the confluence chamber and the reflux chamber are evenly arranged at equal intervals between the confluence chamber and the reflux chamber.

[0012] Furthermore, the diversion channel further includes a reflux pipeline. Two reflux pipelines are symmetrically and fixedly installed on the front side of the cooling diversion box. One end of the reflux pipeline communicates with the end of the rotating filter cylinder, and the other end of the reflux pipeline communicates with the cooling chamber.

[0013] Furthermore, the heat dissipation mechanism includes a refrigeration module and a fan module. The refrigeration module is installed on the cooling diversion box, and the fan module is installed in the cooling diversion box.

[0014] Furthermore, the refrigeration module includes a cold pipe and a temperature adjustment module. The cold pipe is fixedly installed in the cooling chamber, and the temperature adjustment module is installed outside the cooling diversion box. The cold pipe communicates with the temperature adjustment module.

[0015] Furthermore, the fan module includes a turbine and a driving module. The turbine is rotatably installed in the vortex chamber. The air inlet of the turbine is aligned with the cooling chamber, and the air outlet of the turbine is located in the vortex chamber. A driving module for driving the turbine to rotate is installed in the cooling diversion box.

[0016] Furthermore, the adjustment module includes a mounting box, an adjustment motor, a gear, and a gear ring. The mounting box is fixedly installed on the cooling diversion box. The adjustment motor is fixedly installed inside the mounting box, and the output end of the adjustment motor is fixedly installed with a gear. The gear ring is fixedly installed in the middle of the rotating filter cylinder. The gear is meshed with the gear ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The heat dissipation mechanism drives cold air to flow evenly in the cooling diversion box, thereby taking away the heat at the advertising screen, so that the advertising screen is at a suitable operating temperature. During this process, the temperature of each advertising screen during operation is detected by the temperature sensing module. When a certain advertising screen fails to dissipate heat normally, the temperature sensing module in contact with it deforms, and the monitoring module detects the state of the temperature sensing module. Through the cooperation of the temperature sensing module and the monitoring module, it is convenient to judge whether there is an abnormal operation of the advertising screen. Thus, it is convenient to timely discover the advertising screen with abnormal operation and facilitate timely maintenance of the advertising screen with abnormal operation. 2. According to the temperature outside the cooling diversion box, the adjustment module can be controlled to adjust the rotating filter cylinder and simultaneously adjust the state of the ventilation module, changing the air circulation mode in the cooling diversion box. For example, when the temperature outside the cooling diversion box is relatively high, the ventilation module is closed, and the air filter holes on the rotating filter cylinder face the inside of the cooling diversion box, enabling the air inside the cooling diversion box to circulate internally. During this process, the air is filtered through the air filter holes on the rotating filter cylinder, and the dust in the air inside the cooling diversion box is blocked by the rotating filter cylinder. Thus, the dust in the air inside the cooling diversion box is reduced, preventing a large amount of dust from adhering to the advertising screen during circulation and affecting the heat dissipation of the advertising screen. When the temperature outside the cooling diversion box is relatively low, the ventilation module is opened, the air filter holes on the rotating filter cylinder face the outside of the cooling diversion box, and the air enters the cooling diversion box through the air filter holes and is discharged from the ventilation module to achieve external circulation. Thus, the energy consumption can be effectively reduced. When the air filter holes on the rotating filter cylinder face the outside of the cooling diversion box, the air flow direction can be adjusted by the heat dissipation mechanism, enabling the air to enter through the ventilation module and blow out through the rotating filter cylinder from the air filter holes, thereby blowing the dust on the air filter holes to the outside of the cooling diversion box, achieving the cleaning of the rotating filter cylinder.

Detailed implementation manners

[0021] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The "left", "right", "front", "rear", "upper", and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0023] Embodiment 1: In some embodiments, refer to the Figure 1 , Figure 2 and Figure 6 of the accompanying drawings of the specification. The large-size outdoor advertising screen high-temperature heat dissipation device includes a support frame 1, a positioning and monitoring mechanism 2, a cooling diversion box 3, a heat dissipation mechanism 4, and an adjustment mechanism 5; A plurality of groups of advertising screens 11 are uniformly and fixedly installed in a rectangular array on the rear side of the support frame 1; a cooling diversion box 3 is fixedly installed on the front side of the support frame 1; a positioning and monitoring mechanism 2 for detecting the local temperature of the advertising screen 11 is installed between the advertising screen 11 and the cooling diversion box 3; a heat dissipation mechanism 4 is installed in the cooling diversion box 3, and an adjustment mechanism 5 is installed on the front side of the cooling diversion box 3; The positioning and monitoring mechanism 2 includes a plurality of temperature sensing modules and a monitoring module. A plurality of temperature sensing modules that deform with temperature are installed at equal intervals on the front side of the advertising screen 11, and a monitoring module for monitoring the temperature sensing modules is installed on the side of the support frame 1; As Figure 2 shown, the adjustment mechanism 5 includes a rotating filter cylinder 51, an adjustment module 52, and a ventilation module 53. The rotating filter cylinder 51 is rotatably installed on the front side of the cooling diversion box 3, and a plurality of filter air holes 511 are evenly opened at equal intervals on one side of the rotating filter cylinder 51; both ends of the rotating filter cylinder 51 are communicated with the cooling diversion box 3; an adjustment module 52 for adjusting the rotating filter cylinder 51 is installed on the cooling diversion box 3; a ventilation module 53 is installed on the cooling diversion box 3.

[0024] A temperature sensor for monitoring the temperature on the front side of the advertising screen 11 is also fixedly installed in the cooling diversion box 3, and a controller for controlling the positioning and monitoring mechanism 2, the heat dissipation mechanism 4, the adjustment module 52, and the ventilation module 53 is fixedly installed in the cooling diversion box 3.

[0025] A filter screen is provided inside the cooling diversion box 3 on the inner side of the ventilation module 53.

[0026] In this embodiment, when the large-size outdoor advertising screen high-temperature heat dissipation device is working normally, the heat dissipation mechanism 4 drives the cold air to flow evenly in the cooling diversion box 3, thereby taking away the heat at the advertising screen 11 and making the advertising screen 11 operate at a suitable temperature; during this process, the temperature of each advertising screen 11 during operation is detected by the temperature sensing module. When a certain advertising screen 11 is abnormally dissipating heat, the temperature sensing module in contact with it deforms, and the state of the temperature sensing module is detected by the monitoring module; through the cooperation of the temperature sensing module and the monitoring module, it is convenient to judge whether there is an abnormal operation of the advertising screen 11; thus, it is convenient to timely discover the advertising screen 11 with abnormal operation and facilitate timely maintenance of the advertising screen 11 with abnormal operation; Meanwhile, according to the temperature outside the cooling diversion box 3, the control and adjustment module 52 can adjust the rotating filter cylinder 51 and simultaneously adjust the state of the ventilation module 53 to change the air circulation mode in the cooling diversion box 3. For example, when the temperature outside the cooling diversion box 3 is relatively high, the ventilation module 53 is closed, and the air filter holes 511 on the rotating filter cylinder 51 face the inside of the cooling diversion box 3, enabling the internal circulation of the air in the cooling diversion box 3. During this process, the air is filtered through the air filter holes 511 on the rotating filter cylinder 51, and the dust in the air in the cooling diversion box 3 is blocked by the rotating filter cylinder 51, thereby reducing the dust in the air in the cooling diversion box 3 and preventing a large amount of dust from adhering to the advertising screen 11 during circulation, which affects the heat dissipation of the advertising screen 11. When the temperature outside the cooling diversion box 3 is relatively low, the ventilation module 53 is opened, the air filter holes 511 on the rotating filter cylinder 51 face the outside of the cooling diversion box 3, and the air enters the cooling diversion box 3 through the air filter holes 511 and is discharged from the ventilation module 53 to achieve external circulation, thereby effectively reducing energy consumption. When the air filter holes 511 on the rotating filter cylinder 51 face the outside of the cooling diversion box 3, the air flow direction can be adjusted through the heat dissipation mechanism 4, enabling the air to enter through the ventilation module 53 and blow out from the air filter holes 511 through the rotating filter cylinder 51, thereby blowing the dust on the air filter holes 511 to the outside of the cooling diversion box 3 to achieve the cleaning of the rotating filter cylinder 51.

[0027] Embodiment 2: In some embodiments, as a preferred embodiment of the present invention, as Figure 6 shown, the temperature sensing module includes a heat conducting plate 22, a copper plate 23, and a thin-walled metal bellows 24. The heat conducting plate 22 is fixedly installed on the front side of the advertising screen 11, the copper plate 23 is fixedly installed in the middle of the heat conducting plate 22, and multiple groups of closed thin-walled metal bellows 24 are symmetrically and fixedly installed on the copper plate 23. The monitoring module includes a laser sensor 21, and multiple laser sensors 21 for monitoring the thin-walled metal bellows 24 are fixedly installed on the side of the support frame 1. Each laser sensor 21 monitors multiple groups of thin-walled metal bellows 24 in the same row. When the advertising screen 11 is operating normally, the temperatures in front of multiple advertising screens 11 are the same, and at this time, the thin-walled metal bellows 24 do not show obvious deformation; the laser emitted by the laser sensor 21 does not contact the thin-walled metal bellows 24; when a certain advertising screen 11 operates abnormally, causing the temperature in front of the advertising screen 11 to increase, the temperature on the advertising screen 11 is transmitted to the thin-walled metal bellows 24 through the heat conduction plate 22 and the copper plate 23. The gas inside the closed thin-walled metal bellows 24 expands, driving the thin-walled metal bellows 24 to expand and elongate until the laser emitted by the laser sensor 21 contacts the expanded thin-walled metal bellows 24, so as to monitor the deformation of the thin-walled metal bellows 24 through the laser sensor 21; thus, it is possible to timely determine whether there is an advertising screen 11 with abnormal temperature rise caused by abnormal operation, and determine the position of the advertising screen 11 with abnormal temperature rise caused by abnormal operation; it is convenient for timely processing and subsequent maintenance; At the same time, the heat of the advertising screen 11 is transmitted to the thin-walled metal bellows 24 through the heat conduction plate 22 and the copper plate 23. The expansion and contraction amount of the thin-walled metal bellows 24 at the position with a higher temperature is greater than that of the thin-walled metal bellows 24 at the position with a lower temperature, and its surface area increases. Therefore, when cold air flows between the thin-walled metal bellows 24, the heat exchange efficiency of the thin-walled metal bellows 24 with a larger surface area is faster, thereby improving the cooling efficiency of the position with a higher temperature to a certain extent.

[0029] In this embodiment, the air-conditioning compressor 411 is used to transfer heat between the cold pipe 412 and the heat dissipation pipe 413, so that the cold pipe 412 is cooled, thereby cooling the air in the cooling bin 31 where the turbine 421 is located; In the internal air circulation, the fan motor 423 drives the turbine 421 to rotate through the transmission mechanism 422, so that the cooling air in the cooling chamber 31 is accelerated and diffused in the eddy current chamber 32, and is transported to the heat dissipation chamber 33 through the cooling diversion pipe 361. The cold air enters the heat dissipation chamber 33, causing the temperature of the heat dissipation chamber 33 to drop.
