Description

Technical Field

[0001] This invention relates to the field of air pollution control technology, and more specifically, to an air pollution control device. Background Technology

[0002] Haze is a common form of air pollution. The economic and social activities of densely populated areas inevitably emit large amounts of fine particulate matter (PM2.5). Once emissions exceed the atmosphere's circulation capacity and carrying capacity, the concentration of PM2.5 will continue to accumulate. If this is combined with stable weather conditions, large-scale haze is highly likely to occur. Haze not only affects people's travel and reduces driving safety, but prolonged exposure to hazy weather can also harm human health.

[0003] With the continuous advancement of science and technology, currently, spraying drones (such as agricultural drones) equipped with chemical catalysts (such as anti-fog catalysts) can be used to spray over target areas. These catalysts cause pollutant particles in smog (such as PM2.5, aerosols, etc.) to condense or adsorb each other, forming larger particle clusters. As the weight of the particles increases, their suspension capacity in the air decreases, and they eventually fall to the ground, thereby reducing the concentration of pollutants in the air and achieving the purpose of air pollution control.

[0004] Currently, when using spraying drones to perform air pollution control tasks, it is necessary to process multi-source data in real time (such as air quality monitoring, pollutant distribution, flight path planning, etc.) and precisely control the spraying system (such as catalyst flow rate, flight altitude). These tasks rely on the high-performance computing capabilities of the spraying drone's computing chip. This causes the chips in these existing devices to generate more heat during operation, making the thermal paste used to conduct heat to soften and relax under stress, preventing it from adhering tightly between the heat sink and the chip, thus forming air gaps that hinder heat transfer. This, in turn, significantly reduces the heat dissipation effect of the computing chip installed in the spraying drone. Prolonged high-temperature environments may also cause the components inside the chip to fail, leading to task interruption or data loss, affecting the reliability and safety of the spraying drone during air pollution control tasks.

[0005] In view of this, we propose an air pollution control device. Summary of the Invention

[0006] Technical problem to be solved: The purpose of this invention is to provide an air pollution control device that solves the technical problems mentioned in the background section.

Two T-shaped trimming parts are symmetrically slidably arranged in the lower cavity. The lower cavity is also filled with thermal paste that is attached to the control chip at the bottom between the two T-shaped trimming parts. The lower cavity is also equipped with a liquid bladder unit located above the T-shaped trimming part and with its bottom in contact with the thermal conductive paste and having elasticity. The T-shaped trimming section includes a T-shaped sliding section and a retractable multi-media guide structure that is connected to the liquid bladder unit. The multi-media guiding structure includes a thermosensitive expansion section and a cold liquid section. When the thermosensitive expansion section expands due to heat, it injects the cold liquid section into the liquid bladder unit, causing the liquid bladder unit to undergo elastic protrusion deformation in the direction of the heat-guiding paste.

The lower cavity includes an embedded cavity disposed inside the heat-conducting plate and a heat transfer cavity disposed at the bottom of the heat-conducting plate. The heat transfer cavity is disposed at the bottom of the heat-conducting plate, and the embedded cavity is located between the inverted trapezoidal chamber and the heat transfer cavity.

[0012] As an optional solution to the technical solution of this invention, the liquid bladder unit includes a sheet-shaped elastic liquid bladder that is fixedly connected to the embedded cavity and is filled with a cold liquid portion. The bottom of the sheet-like elastic liquid bladder is uniformly connected with multiple front-end heating terminals, and the bottom surface of the front-end heating terminals is flush with the bottom surface of the sheet-like elastic liquid bladder. Each front-end heating terminal is connected to a central heating wire; The top surface of the sheet-like elastic liquid bladder is connected to the rear heat transfer plate, and the end of the middle heat-inducing wire away from the front heat-inducing terminal extends into the inner cavity of the sheet-like elastic liquid bladder and then passes through the top wall of the sheet-like elastic liquid bladder and connects to the rear heat transfer plate. The top of the rear heat transfer plate is connected to a moisture-absorbing pad that absorbs low-boiling-point liquids. Both ends of the sheet-like elastic fluid bladder are fixedly connected to fluid distribution hoses filled with cold liquid.

[0013] As an optional solution to the technical solution of this invention, the multi-medium guiding structure includes a horizontally positioned chamber disposed inside the heat-generating plate; The transverse chamber has a driven plug body that slides in a sealed manner. A power arm is connected to the driven plug body. The transverse chamber is also equipped with a return spring, with one end of the return spring connected to the end of the transverse chamber and the other end connected to the driven plug body. In the multi-media guiding structure, both the thermosensitive expansion section and the cold liquid section are filled in the transverse chamber, and the driven plug section is located between the thermosensitive expansion section and the cold liquid section.

[0014] As an optional solution to the technical solution of this invention, the end of the power boom away from the driven plug body is sealed through the end of the transverse chamber and extends into the heat transfer cavity and is connected to its corresponding plastic extrusion block.

[0015] As an optional solution to the technical solution in this invention document, the heat transfer cavity is located between two horizontally placed chambers.

[0016] As an optional solution to the technical solution of this invention, the opposite ends of the two fluid distribution hoses are inserted into the interior of the heat-generating plate and connected to one end of each of the two horizontally placed chambers near the cold liquid section.

[0017] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. In the process of controlling air pollution using the device of the present invention, the control unit used to process the data during the control process can sense the state of the thermal paste coated between the heat sink and the control chip. When the thermal paste softens due to heat and cannot adhere tightly between the control chip and the heat sink, the control unit can reshape the softened thermal paste, thereby making it adhere tightly between the control chip and the heat sink again. This achieves active compensation for the heat dissipation capacity of the chip, enhances the heat dissipation effect on the control chip, and improves the reliability of the device in performing air pollution control tasks.

[0018] 2. The heat generated by the control chip during operation in the control unit is conducted to the heat sink through two conduction paths. One path is through the silicone thermal pad, and the other is through the thermal paste. When the thermal paste softens due to heat, the heat conduction path is blocked, causing heat to accumulate inside the control chip housing. When the temperature of the control chip housing reaches the preset temperature range (i.e., the phase change temperature of the thermal expansion section), the thermal expansion section expands due to heat, driving the shaping extrusion block through the power arm. This reshapes the softened thermal paste and tightly adheres it between the control chip and the heat sink, thus actively compensating for the chip's heat dissipation capacity.

[0019] 3. When the temperature of the control chip reaches the preset temperature range, and the two molding extrusion blocks move towards each other to squeeze and gather the softened thermal paste, the extrusion action of the convex part in the molding process reshapes the extruded thermal paste into an "hourglass shape" that is thick at both ends and thin in the middle. This allows the thermal paste to adhere tightly to the control chip and the heat sink, while also increasing the contact area between the thermal paste and the control chip and the heat sink. This allows the softened thermal paste to accurately fill the gaps in the heat transfer cavity that need to be filled, increasing the surface area for heat conduction, ensuring the continuity and effectiveness of heat transfer, and better guiding heat from the control chip (i.e., the heat source) to the heat sink (i.e., the heat dissipation area), thus ensuring the heat dissipation effect on the control chip.

[0020] 4. After the softened thermal paste is shaped by the extrusion block and the protrusion in the molding process, the heat from the control chip is continuously transferred to the heat sink plate and the liquid bladder unit through the thermal paste. While the heat is dissipated to the external environment through the heat sink plate, it can also be absorbed by the cold liquid in the liquid bladder unit under the heat conduction effect of the front heat sink terminal and the middle heat sink wire, thus achieving the cooling and heat dissipation treatment of the heat generated by the control chip during operation.

[0021] 5. The high heat generated by the convex part during full-load operation in the molding process is continuously conducted to the heat sink plate through thermal paste and silicone thermal pad. Due to the limited heat dissipation performance of the heat sink plate, it is difficult to dissipate in time and is continuously absorbed by the cold liquid part in the liquid bladder unit. As the temperature of the cold liquid part continues to rise, its heat energy is continuously conducted to the rear heat transfer plate through the middle heat sink wire. The low boiling point liquid absorbed by the hygroscopic pad continuously absorbs the heat energy transferred from the rear heat transfer plate and gradually absorbs heat and evaporates. When the vapor formed by evaporation comes into contact with the hollow heat sink or the inner wall of the heat sink plate, it cools down and liquefies into water droplets, which fall onto the bottom wall of the inverted trapezoidal chamber. Then, it is absorbed again by the hygroscopic pad along the inclined bottom wall of the inverted trapezoidal chamber, realizing auxiliary circulation heat dissipation for the control chip in operation, which is conducive to further enhancing the cooling effect of the control chip in operation.

[0022] 6. During the process of the thermal grease softening under heat and being reshaped by the molding extrusion block and the protrusion in the molding process, driven by the thermally expanding thermosensitive expansion and contraction part, the driven plug continuously squeezes and injects the cold liquid into the sheet-like elastic liquid bladder. The hydraulic pressure inside the sheet-like elastic liquid bladder increases and drives its bottom wall to bulge outward elastically. Furthermore, as the bottom of the sheet-like elastic liquid bladder bulges outward continuously, it squeezes the thermal grease, making the thermal grease more fully fill the hourglass-shaped cavity formed by the heat transfer chamber, the molding extrusion block, and the protrusion in the molding process. This makes the thermal grease more fully and tightly adhered between the control chip and the heat sink plate. At the same time, the bulge at the bottom of the sheet-like elastic liquid bladder further increases the contact area between the liquid bladder unit and the thermal grease, thereby further improving the heat transfer efficiency of the heat generated by the control chip during operation. This ensures the heat dissipation effect of the control chip in the control unit during the air pollution control process, and thus enables the device to operate stably and reliably during the air pollution control task.

[0028] Reference Figures 1 to 11 This invention provides an air pollution control device, including a spraying drone 100 and an information processing module mounted on the spraying drone 100. The spraying drone 100 is an existing agricultural or industrial device that achieves automated and precise operations through drone technology. It is mainly used for the efficient and safe spraying of liquid substances such as pesticides, fertilizers, herbicides, seeds, and disinfectants. It combines the high mobility, precise positioning system, and intelligent control technology of drones, significantly improving the efficiency and safety of traditional spraying operations. The spraying drone 100 in this invention is preferably an agricultural drone. Before the device performs air pollution control tasks, an anti-fog catalyst to eliminate smog needs to be added to the water tank of the spraying drone. The information processing module includes a housing and a control unit disposed inside the housing; The control unit includes a control chip 203 and a cold-processing structure that is attached to the surface of the control chip 203; The cold treatment structure includes an inverted trapezoidal chamber 207 arranged above and below, and a lower cavity. Two T-shaped trimming parts are symmetrically slidably arranged in the lower cavity. The lower cavity is also filled with thermal paste 206 whose bottom is attached to the control chip 203 between the two T-shaped trimming parts. The lower cavity is also equipped with a liquid bladder unit located above the T-shaped trimming part and with its bottom attached to the thermal conductive paste 206 and having elasticity. The T-shaped trimming section includes a T-shaped sliding section and a retractable multi-media guide structure that is connected to the liquid bladder unit. The multi-media guiding structure includes a thermosensitive expansion section 210 and a cold liquid section 216. When the thermosensitive expansion section 210 is heated and expands, the cold liquid section 216 is injected into the liquid bladder unit, and the liquid bladder unit undergoes elastic protrusion deformation in the direction of the heat-guiding paste 206. The thermosensitive expansion section 210 is made of paraffin material, and the phase transition temperature of the paraffin is 45°C to 60°C.

[0029] In the process of controlling air pollution using the device of the present invention, the control unit used to process the data during the control process can sense the state of the thermal paste 206 coated between the heat-conducting plate 204 and the control chip 203. When the thermal paste 206 softens due to heat and cannot adhere tightly between the control chip 203 and the heat-conducting plate 204, the control unit can reshape the softened thermal paste 206, so that the softened thermal paste 206 adheres tightly between the control chip 203 and the heat-conducting plate 204 again. This achieves active compensation for the heat dissipation capacity of the chip, enhances the heat dissipation effect of the control chip 203, and improves the reliability of the device in performing air pollution control tasks.

[0030] Reference Figure 1 and Figure 3 The present invention provides an air pollution control device, the cover of which includes an insulating protective shell 208 connected to a spraying drone 100; The top opening of the insulating housing 208 is sealed with an upper sealing top cover 217; A heat dissipation vent is provided on the side wall of the insulating shell 208, and a dustproof net is connected to the side wall of the insulating shell 208 at the position corresponding to the heat dissipation vent to cover the opening of the heat dissipation vent. A cooling fan 300 is also connected inside the insulating housing 208 at the location corresponding to the heat dissipation vent. When the device is running, the cooling fan 300 continuously dissipates the heat energy accumulated inside the insulating housing 208 to the external environment, and the dustproof net prevents dust from the external environment from entering the inner cavity of the insulating housing 208.

[0031] Reference Figures 3 to 5 The present invention provides an air pollution control device, the control unit of which also includes a circuit board 201 connected to the control chip 203 and fixedly installed in the cavity of the insulating shell 208.

[0032] Reference Figures 3 to 7 The present invention provides an air pollution control device, the cold treatment structure of which also includes a heat-generating plate 204; A silicone thermal pad 205 is connected to the bottom of the heat sink 204, and a fixed support foot is connected to the side wall of the heat sink 204. The heat sink 204 is fixedly installed on the circuit board 201 through the fixed support foot. The inverted trapezoidal cavity 207 is disposed inside the heat-drawing plate 204, and a number of hollow heat sinks 202 with internal cavities connected to the inverted trapezoidal cavity 207 are connected to the top of the heat-drawing plate 204 at the position corresponding to the position of the inverted trapezoidal cavity 207. The lower cavity includes an embedded cavity disposed inside the heat-conducting plate 204 and a heat transfer cavity disposed at the bottom of the heat-conducting plate 204. The heat transfer cavity is disposed at the bottom of the heat-conducting plate 204, and the embedded cavity is located between the inverted trapezoidal chamber 207 and the heat transfer cavity. The top wall of the embedded cavity is also provided with a number of openings that are connected to the inverted trapezoidal cavity 207 at the corresponding positions.

[0033] Reference Figures 5 to 7 The present invention provides an air pollution control device, wherein the T-shaped sliding part includes a plastic extrusion block 209 that slides within a heat transfer cavity; The shaping extrusion block 209 has a shaping convex part 213 in the middle, and the shape of the inner cavity of the structure formed by the heat transfer cavity and the two T-shaped sliding parts is "hourglass".

[0034] Reference Figure 5 and Figure 6 The present invention provides an air pollution control device, wherein the multi-media guiding structure includes a horizontally placed chamber disposed inside the heat-generating plate 204; A driven plug body 211 is sealed and slidably inside the transverse chamber. A power arm 212 is connected to the driven plug body 211. A return spring is also provided in the transverse chamber, with one end of the return spring connected to the end of the transverse chamber and the other end connected to the driven plug body 211. In the multi-medium guiding structure, the thermosensitive expansion section 210 and the cold liquid section 216 are both filled in the transverse cavity, and the driven plug section 211 is located between the thermosensitive expansion section 210 and the cold liquid section 216. The end of the power boom 212 away from the driven plug body 211 is sealed through the end of the transverse chamber and extends into the heat transfer cavity and is connected to its corresponding plastic extrusion block 209. The heat transfer cavity is located between two horizontally positioned chambers.

[0035] The heat generated by the control chip 203 during operation is conducted to the heat sink 204 through two conduction paths: one through the silicone thermal pad 205 and the other through the thermal paste 206. When the thermal paste 206 softens due to heat, the heat conduction path is blocked, causing heat to accumulate inside the housing of the control chip 203. When the temperature of the housing of the control chip 203 reaches the preset temperature range (i.e., the phase change temperature of the thermal expansion part 210), the thermal expansion part 210 expands due to heat, driving the shaping extrusion block 209 through the power arm 212. This reshapes the softened thermal paste 206 and tightly adheres it between the control chip 203 and the heat sink 204, thus achieving active compensation for the chip's heat dissipation capacity.

[0036] When the temperature of the control chip 203 reaches the preset temperature range, and the two molding extrusion blocks 209 move towards each other to squeeze and gather the softened thermal paste 206, the extruded thermal paste 206 is reshaped into an hourglass shape with thicker ends and a thinner middle under the squeezing action of the protrusion 213 in the molding process. This allows the thermal paste 206 to adhere tightly between the control chip 203 and the heat sink 204, while also increasing the contact area between the thermal paste 206 and the control chip and the heat sink. This allows the softened thermal paste 206 to accurately fill the gaps in the heat transfer cavity, increasing the surface area for heat conduction, ensuring the continuity and effectiveness of heat transfer, and better guiding heat from the control chip 203 (i.e., the heat source) to the heat sink 204 (i.e., the heat dissipation area), thus ensuring the heat dissipation effect on the control chip 203.

[0037] Reference Figures 7 to 11 The present invention provides an air pollution control device, wherein the liquid bladder unit includes a sheet-shaped elastic liquid bladder 215 fixedly connected to the inner cavity and filled with a cold liquid portion 216. The bottom of the sheet-like elastic liquid bladder 215 is evenly connected with a plurality of front-end heat-inducing terminals 219, and the bottom surface of the front-end heat-inducing terminals 219 is flush with the bottom surface of the sheet-like elastic liquid bladder 215. Each front-end heat-generating terminal 219 is connected to a central heat-generating wire 220; The top surface of the sheet-like elastic liquid bladder 215 is connected to the rear heat transfer plate 221, and the end of the middle heat-drawing wire 220 away from the front heat-drawing terminal 219 extends into the inner cavity of the sheet-like elastic liquid bladder 215 and then passes through the top wall of the sheet-like elastic liquid bladder 215 and is connected to the rear heat transfer plate 221. The top of the rear heat transfer plate 221 is connected to a moisture-absorbing thin pad 218 that absorbs low-boiling-point liquid inside, and the low-boiling-point liquid absorbed in the moisture-absorbing thin pad 218 is preferably liquid ammonia. Both ends of the sheet-like elastic liquid bladder 215 are fixedly connected to a fluid distribution hose 214 filled with a cold liquid section 216. The opposite ends of the two fluid distribution hoses 214 are inserted into the heat-conducting plate 204 and connected to the end of each of the two horizontally placed chambers near the coolant section 216.

[0038] After the softened thermal paste 206 is shaped by the molding extrusion block 209 and the protrusion 213 in the molding process, the heat at the control chip 203 is continuously transferred to the heat sink plate 204 and the liquid bladder unit through the thermal paste 206. While the heat is dissipated to the external environment through the heat sink plate 204, it can also be absorbed by the cold liquid part 216 in the liquid bladder unit under the heat conduction effect of the front heat sink terminal 219 and the middle heat sink wire 220, so as to achieve the cooling and heat dissipation treatment of the heat generated by the control chip 203 during operation.

[0039] The high heat generated by the protruding part 213 during full-load operation is continuously conducted to the heat-conducting plate 204 via the thermal paste 206 and the silicone thermal pad 205. Due to the limited heat dissipation performance of the heat-conducting plate 204, the heat is difficult to dissipate in time and is continuously absorbed by the cold liquid part 216 in the liquid bladder unit. As the temperature of the cold liquid part 216 continues to rise, its heat energy is continuously conducted to the rear heat transfer plate 221 through the middle heat-conducting wire 220. The low-boiling-point liquid absorbed in the moisture-absorbing pad 218 is continuously absorbed. The heat energy transferred from the heat transfer plate 221 is gradually absorbed and evaporated. When the vapor formed by evaporation comes into contact with the inner wall of the hollow heat sink 202 or the heat plate 204, it cools down and liquefies into water droplets that fall onto the bottom wall of the inverted trapezoidal chamber 207. The water droplets are then absorbed again by the moisture-absorbing pad 218 along the inclined bottom wall of the inverted trapezoidal chamber 207, thus achieving auxiliary circulating heat dissipation for the control chip 203 in operation. This further enhances the cooling effect on the control chip 203 in operation.

[0040] During the process of the thermal paste 206 softening under heat and being reshaped by the molding extrusion block 209 and the molding protrusion 213, driven by the thermally expanding thermosensitive expansion and contraction part 210, the driven plug part 211 continuously squeezes and injects the cold liquid part 216 into the sheet-like elastic liquid bladder 215. The hydraulic pressure inside the sheet-like elastic liquid bladder 215 increases and drives its bottom wall to elastically bulge outward. Furthermore, as the bottom of the sheet-like elastic liquid bladder 215 continuously bulges outward, it squeezes the thermal paste 206, making the thermal paste 206 more fully fill the heat transfer chamber, molding extrusion block 209, and molding protrusion 213. Within the hourglass-shaped cavity formed by the protrusion 213, the thermal paste 206 adheres more fully and tightly to the control chip 203 and the heat sink 204. At the same time, the protrusion at the bottom of the sheet-like elastic liquid bladder 215 further increases the contact area between the liquid bladder unit and the thermal paste 206, thereby further improving the heat transfer efficiency of the heat generated by the control chip during operation. This ensures the heat dissipation effect of the control chip 203 in the control unit during the air pollution control process, and enables the device to operate stably and reliably during the air pollution control task.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
