Description

Technical Field

[0001] This application relates to the field of transmission equipment technology, and more specifically, to a heat dissipation auxiliary system for an outdoor shortwave transmitter. Background Technology

[0002] Shortwave amplitude modulation (AM) transmitters generate a significant amount of heat during operation, especially in summer or under sustained high temperatures. Their own heat dissipation capacity is often insufficient, easily leading to overheating and affecting the stability of the transmitted signal and the lifespan of the equipment. To improve heat dissipation, using coolant (such as water) to absorb heat through evaporation is a relatively stable and effective method.

[0003] However, to ensure communication quality and reduce ground interference, such transmitters typically need to be installed on poles or towers of a certain height. This installation requirement presents a dilemma in the placement of the auxiliary cooling system: placing the coolant tank directly near the transmitter at a high location would significantly increase the load and torque on the top of the pole, potentially leading to structural fatigue or even damage over time, posing a safety hazard; while placing the coolant source on the ground would avoid additional structural load, but due to the distance from the transmitter's heat dissipation surface at a high altitude, the evaporating water vapor would be difficult to effectively guide and act on the heat-generating components, resulting in low heat dissipation efficiency.

[0004] Therefore, there is a lack of existing technologies that can effectively utilize coolant evaporation for heat dissipation while also ensuring the safety of the installation structure and heat dissipation efficiency. Summary of the Invention

[0005] The purpose of this application is to provide a heat dissipation auxiliary system for an outdoor shortwave transmitter, which has structural safety and can improve heat dissipation efficiency, thereby improving the above-mentioned problems.

[0006] This application is achieved through the following technical solution:

[0007] This application provides a field-type shortwave transmitter heat dissipation auxiliary system. The transmitter has a heat dissipation surface with a heat dissipation vent. The field-type shortwave transmitter heat dissipation auxiliary system includes a mounting rod, a vacuum generator, and a liquid extraction device. The mounting rod is divided into a liquid storage chamber and a heat dissipation chamber along its length. The liquid storage chamber is located on the ground and stores coolant at its inner bottom. The top of the heat dissipation chamber has an air outlet. The vacuum generator is located at the air outlet and is used to create a negative pressure in the heat dissipation chamber. The transmitter is mounted on the side wall of the mounting rod, and its heat dissipation surface is located in the heat dissipation chamber. The liquid extraction device includes a lifting mechanism and a liquid extraction component. The lifting mechanism drives the liquid extraction component to reciprocate between the liquid storage chamber and the heat dissipation chamber. The liquid extraction component is configured to: immerse itself in the coolant in the liquid storage chamber to extract coolant when descending, and carry the extracted coolant into the heat dissipation chamber for evaporation and heat dissipation when rising.

[0008] In this technical solution, the heavy coolant is stored in a ground-level reservoir, avoiding the additional load and bending moment caused by placing a water tank at the top of the mounting pole or at a high location. This reduces the long-term fatigue risk of the pole structure and ensures the stability and safety of the installation structure. Simultaneously, a liquid extraction device actively delivers the coolant to the heat dissipation cavity where the heat-generating components (heat dissipation surface) are located. A negative pressure environment created by a vacuum generator enhances evaporation and airflow guidance, ensuring that the evaporative cooling effect directly and efficiently acts on the core heat-generating area, overcoming the drawbacks of long-distance ground-based liquid sources and poor heat dissipation. The system constructs an active cycle of extraction, lifting, evaporation, and discharge. Compared to passive reliance on natural evaporation or infiltration, this cycle is controllable and reliable, its heat dissipation capacity is independent of ambient wind speed, and the negative pressure enhances evaporation efficiency, resulting in significant and stable heat dissipation performance. Coolant replenishment, observation, and maintenance are all completed on the ground, eliminating the need to climb to higher locations and simplifying daily operation and maintenance.

[0009] Preferably, the lifting stroke of the liquid-collecting component has a first limit position and a second limit position. When the liquid-collecting component is at the first limit position, it is located in the heat dissipation cavity. When the liquid-collecting component is at the second limit position, it is immersed in the coolant in the liquid storage cavity. The side wall of the heat dissipation cavity is provided with multiple air inlets. In the height direction of the mounting rod, the heat dissipation surface is located between the air inlets and the air outlet. At least some of the air inlets are arranged around the liquid-collecting component at the first limit position.

[0010] In this application's technical solution, a directional airflow path is constructed by the height relationship between the air inlet, heat dissipation surface, and air outlet. Cold air enters from below, naturally flowing through the heating element (heat dissipation surface) in the middle for initial heat exchange, and then continues to rise, carrying away moisture. This conforms to the physical principle of hot air rising, resulting in smooth airflow, low resistance, and high heat dissipation efficiency. By surrounding the liquid-collecting component at the evaporation location with some air inlets, external air is directly guided to the coolant surface, providing ample fresh air supply for the evaporation process and enhancing the evaporation rate and heat absorption effect. This solves the problem of low evaporation efficiency when relying solely on static air within the cavity, achieving active air supply for the evaporative cooling process. After entering the heat dissipation cavity, part of the air directly cools the heat dissipation surface, while the other part enhances the evaporative cooling of the liquid-collecting component. The two airflows mix within the cavity before being discharged, allowing a single airflow to complete two forms of heat dissipation tasks sequentially or simultaneously. This results in high system integration, synergistic heat dissipation capabilities, and superior performance compared to a single heat dissipation method.

[0011] Preferably, the liquid-collecting component includes a base connected to the output end of the lifting mechanism, and a liquid-absorbing sponge disposed on the base.

[0012] In this application's technical solution, a liquid-absorbing sponge is used as the liquid storage medium. It requires no additional pumps, valves, or precision metering devices; relying solely on the material's inherent properties, it automatically and quickly absorbs and stores coolant upon immersion, and securely locks the liquid in place during lifting, preventing leakage during transport. This simplifies the auxiliary system structure while improving reliability. The porous structure of the liquid-absorbing sponge not only stores the liquid but also creates a large effective surface area for evaporation within the heat dissipation chamber. Compared to smooth flat plates or containers, this structure allows the coolant to have greater contact with circulating air, resulting in a higher cooling power release per unit time during the evaporation and heat absorption process. The modular design of the base and liquid-absorbing sponge makes the liquid-collecting component simple in structure and low in cost. As a consumable part, the sponge can be easily removed from the base for replacement, cleaning, or dehydration (if the liquid carrying capacity needs adjustment), making maintenance convenient. This design also allows for easy adjustment of the sponge's volume, shape, or porosity according to heat dissipation requirements.

[0013] Preferably, the mounting rod includes a first rod body and a second rod body. The first rod body is close to the ground, the air outlet is located at the top of the second rod body, and the transmitter is mounted on the second rod body. The first rod body and the second rod body are interconnected, and the top of the first rod body extends into the inner side of the second rod body. The inner wall of the portion of the first rod body located inside the second rod body is provided with a partition. With the partition as the boundary, the internal space of the portion of the first rod body facing the ground constitutes a liquid storage chamber, and the internal space of the portion of the first rod body facing away from the ground and the internal space of the second rod body together constitute a heat dissipation chamber. An opening is provided in the center of the partition for the liquid-absorbing sponge to pass through. When the liquid-taking device is at the first extreme position, the liquid-absorbing sponge passes through the partition and extends into the heat dissipation chamber, and in the height direction of the mounting rod, the liquid-absorbing sponge extends beyond the first rod body.

[0014] The technical solution of this application integrates three major functions—liquid storage, heat dissipation, and support—into a single rod system. Through a nested rod-within-a-rod design, a stable liquid storage foundation is established near the ground, while a heat dissipation duct is constructed using the space of the upper rod, achieving seamless vertical integration and space reuse. The entire system appears as a single rod, with an extremely compact structure, small footprint, and high industrial integration. The partition acts like a valve floor, isolating the liquid storage chamber (wet zone) and the heat dissipation chamber (dry zone), preventing excessive backflow of coolant vapor or accidental liquid entry into the heat dissipation chamber and interference with the equipment. Simultaneously, its central opening provides a unique, controlled vertical channel for the absorbent sponge, ensuring precise movement of the liquid extraction component between the two chambers with the shortest path and highest efficiency. Since the heat dissipation chamber is formed by the annular space between the inner wall of the second rod and the outer wall of the upper section of the first rod, when airflow enters from the air inlet on the side wall of the second rod, it naturally forms a flow around the upper section of the first rod (where the absorbent sponge is evaporating). This circumferential flow increases the contact area and contact time between air and the moist absorbent sponge and the transmitter heat dissipation surface mounted on the outer wall of the second rod (heat is conducted through the rod wall or directly radiated), thereby improving the overall heat exchange efficiency.

[0015] Preferably, when the liquid-collecting component is in the first extreme position, the base and the surface of the partition facing the ground are pressed together to close the opening on the partition, so that the base, the partition and the inner wall of the first rod together form a tank structure for receiving the coolant flowing out from the liquid-absorbing sponge.

[0016] The technical solution of this application solves the problem of potential leakage or ineffective backflow of liquid in evaporative cooling systems. It ensures that every drop of coolant lifted into the cooling chamber is locked within the effective working area (either evaporating in the absorbent sponge or temporarily stored in the receiving tank). This prevents liquid from falling directly back to the bottom of the storage chamber without sufficient evaporation, avoiding coolant waste and maximizing the utilization of coolant lifted each time. When the liquid-receiving component is in the working position (i.e., the liquid-receiving component is in the first extreme position), the sealing of the opening by the base essentially isolates the cooling chamber (negative pressure, high temperature, high humidity) from the storage chamber (normal pressure, normal temperature). This helps maintain the stable negative pressure and airflow organization established by the vacuum generator within the cooling chamber, preventing it from being disturbed by air from the storage chamber; it also reduces the diffusion of hot and humid air from the cooling chamber to the storage chamber, delaying natural evaporation loss and potential contamination of the coolant. The free surface of the liquid stored within the formed tank structure itself is also an evaporation surface. Although this surface is smaller than the surface area of ​​the absorbent sponge and is located in a secondary position in the airflow path, it can still contribute some of the evaporative heat dissipation, forming a beneficial supplementary heat dissipation mechanism. As the upper part of the absorbent sponge gradually dries, the liquid in the tank may be reabsorbed by the bottom of the sponge through capillary action, realizing the reuse of the liquid.

[0017] Preferably, the lifting mechanism includes a winch and a traction rope. One end of the traction rope is connected to the output end of the winch, and the other end is connected to the base. The traction rope is elastic, and the winch pulls the base up and down by winding or releasing the traction rope. When the liquid picker is at the first limit position, the traction rope pulls the base and the partition together under its own elasticity.

[0018] In the technical solution of this application, the introduction of the elastic traction rope is equivalent to adding an automatic tensioner to the tightness between the base and the partition. Even if the contact surface of the partition or base deforms or shifts due to temperature changes, minor wear, or vibration during use, the continuous rebound force of the elastic rope can immediately compensate for this gap and adaptively maintain sufficient sealing pressure. This is much more reliable than rigid connections or simple limiting methods, improving the sealing stability of the auxiliary system during long-term operation. The auxiliary system provided by this application adopts a hoist and traction rope lifting method, which is simple in structure, technically mature, and low in cost. At the same time, the elastic rope itself can buffer the impact and vibration during operation, protecting both the motor and the structure. Even in the event of a power outage, the self-locking braking function of the hoist and the tension of the elastic rope can safely hold the liquid-receiving component in its current position, preventing it from suddenly falling.

[0019] Preferably, a sealing element is provided at the edge of the surface of the base facing the partition; when the liquid taking element is in the first extreme position, the sealing element is located between the partition and the base to form a sealed connection.

[0020] In the technical solution of this application, the sealing element ensures that there is almost no exchange of gas and moisture between the heat dissipation chamber and the liquid storage chamber during the heat dissipation operation phase. This maintains a stable negative pressure environment within the heat dissipation chamber, ensuring the working efficiency of the vacuum generator and the controllability of airflow organization, while effectively preventing hot and humid air from entering the liquid storage chamber and causing unnecessary temperature rise or contamination of the coolant. A reliable sealing connection ensures the integrity of the temporary tank structure formed by the base, partition, and inner wall of the first rod. It prevents liquid collected in the tank from leaking back into the liquid storage chamber through gaps in the contact surface or improperly spreading along the gaps, further reducing ineffective liquid loss. The elastic sealing element has excellent following and compensation capabilities. Even if the system experiences thermal expansion and contraction of metal components due to temperature changes, or slight wear due to long-term use, the sealing element can continuously compensate for these changes through its own elastic deformation, maintaining effective sealing force. This improves the reliability and maintenance-free cycle of the auxiliary system under different climatic conditions during long-term operation.

[0021] Preferably, the portion of the transmitter located outside the heat dissipation cavity is also equipped with an exhaust fan, which is used to draw outside air into the transmitter and then send it into the heat dissipation cavity through the heat dissipation vent; the power of the vacuum generator is greater than the power of the exhaust fan.

[0022] The technical solution of this application adds a new, active heat dissipation path, achieving efficient synergy between internal air cooling and cavity evaporative cooling. The exhaust fan is responsible for solving the problem of heat accumulation inside the transmitter, directly carrying the heat to the heat dissipation cavity; while the original system (vacuum generator and liquid extraction evaporation) is responsible for handling the overall heat load accumulated in the heat dissipation cavity. The combination of the two forms a comprehensive heat dissipation system from the inside out and from point to surface, with a heat dissipation effect superior to that of a single method.

[0023] Preferably, the field-type shortwave transmitter heat dissipation auxiliary system further includes a first sensor, a memory, and a control module. The first sensor is set on the base and is used to detect the actual weight of the absorbent sponge. The memory is used to store a preset weight threshold of the absorbent sponge. The control module is configured to control the start and stop of the lifting mechanism based on the comparison result between the actual weight detected by the first sensor and the preset weight threshold.

[0024] In this application's technical solution, by monitoring the actual weight of the absorbent sponge, the auxiliary system can directly sense the real-time state (liquid content) of the heat dissipation medium, thereby precisely triggering the action at the moment when coolant replenishment is most needed. This avoids the problems of insufficient coolant intake (leading to heat dissipation interruption) or premature coolant intake (the sponge is still very wet, wasting energy and potentially reducing airflow within the cavity) that may occur at fixed time intervals, ensuring that the heat dissipation process remains within the high-efficiency range and saving energy consumption for the lifting mechanism. The auxiliary system can automatically adapt to the influence of different environmental conditions (such as temperature, humidity, and wind speed) on the evaporation rate. When evaporation is rapid in dry and hot weather, the coolant intake frequency will automatically increase; when evaporation is slow in humid and cool weather, the coolant intake frequency will automatically decrease. This adaptive capability ensures the stability of the heat dissipation effect, reduces reliance on manual intervention, and improves operational reliability under all weather conditions.

[0025] Preferably, the field-type shortwave transmitter heat dissipation auxiliary system further includes a second sensor, a memory, and a control module. The second sensor is set inside the heat dissipation cavity to detect the actual temperature of the heat dissipation cavity; the memory is used to store a preset temperature threshold of the heat dissipation cavity; and the control module is configured to control the start and stop of the lifting mechanism based on the comparison result between the actual temperature detected by the second sensor and the preset temperature threshold.

[0026] In the technical solution of this application, when the transmitter power increases or the ambient temperature rises, causing a sudden increase in the cavity temperature, the auxiliary system can respond immediately by increasing the coolant supply to enhance heat dissipation, thereby directly and quickly preventing the transmitter from experiencing performance degradation or damage due to overheating. Unlike fixed-time or simple weight control, in low-load transmitter or cool environments, the heat dissipation requirement is low, and the system can remain stationary for extended periods, reducing unnecessary operation and mechanical wear of the lifting mechanism, achieving energy savings and extending component lifespan. Only when the heat load actually exists and reaches a certain level can the evaporative cooling resources be activated, ensuring a precise match between the auxiliary system's operation and heat dissipation requirements.

[0043] According to some embodiments of this application, optionally, such as Figures 1-7 As shown, this application provides a field-type shortwave transmitter heat dissipation auxiliary system. The transmitter 1 has a heat dissipation surface 10 with a heat dissipation vent. The field-type shortwave transmitter heat dissipation auxiliary system includes a mounting rod 2, a vacuum generator, and a liquid extraction device 3. The mounting rod 2 is divided into a liquid storage chamber 20 and a heat dissipation chamber 21 along its length. The liquid storage chamber 20 is located on the ground and stores coolant at its inner bottom. The top of the heat dissipation chamber 21 is provided with an air outlet 210. The vacuum generator is located at the air outlet 210 and is used to create a negative pressure in the heat dissipation chamber 21. The transmitter 1 is mounted on the side wall of the mounting rod 2, and its heat dissipation surface 10 is located in the heat dissipation chamber 21. The liquid extraction device 3 includes a lifting mechanism 30 and a liquid extraction component 31. The lifting mechanism 30 drives the liquid extraction component 31 to reciprocate between the liquid storage chamber 20 and the heat dissipation chamber 21. The liquid extraction component 31 is configured to: immerse itself in the coolant in the liquid storage chamber 20 to extract coolant when descending, and carry the extracted coolant into the heat dissipation chamber 21 to evaporate and dissipate heat when rising.

[0044] The coolant mentioned in this application may be, but is not limited to, water, ethanol, or a mixture of water and ethanol.

[0045] In practical applications, the mounting rod 2 is first securely installed on the ground. Its bottom liquid storage chamber 20 serves as a storage container for coolant (e.g., water), and daily replenishment and maintenance are completed on the ground, which is convenient and safe. The transmitter 1 is directly fixedly installed at a predetermined position on the side wall of the mounting rod 2, ensuring its heat dissipation surface 10 is completely within the heat dissipation chamber 21 on the upper part of the mounting rod 2. After the system is started, the vacuum generator (e.g., an exhaust fan) located at the air outlet 210 at the top of the heat dissipation chamber 21 begins to operate, creating a stable negative pressure environment within the sealed or semi-sealed heat dissipation chamber 21. Simultaneously, the liquid extraction device 3 begins to operate: the lifting mechanism 30 (e.g., a screw or winch 300 driven by a motor) drives the liquid extraction component 31 (e.g., a porous suction block or a grooved lifting plate) downwards, immersing it in the coolant in the liquid storage chamber 20 and fully extracting it. Subsequently, the lifting mechanism 30 drives the liquid extraction component 31 upwards, lifting the coolant it carries into the heat dissipation chamber 21. When the coolant enters the negative pressure and high-temperature environment of the heat dissipation chamber 21, its evaporation rate increases significantly. The evaporation process absorbs a large amount of heat, primarily from the radiation and convection of the transmitter 1's heat dissipation surface 10 into the air within the chamber. Under negative pressure, the water vapor generated by the coolant evaporation, along with the heated air, is orderly discharged from the top air outlet 210, thus continuously and efficiently removing heat from the heat dissipation chamber 21 and the transmitter 1 body. The coolant extraction device 3 continuously rises and falls, achieving a cycle of continuously and in small batches transporting ground-level coolant to the vicinity of the high-level heat dissipation surface 10 for evaporation and heat dissipation.

[0046] The vacuum generator is not only used to create negative pressure to accelerate liquid evaporation, but its more crucial role is to form a directional airflow from the bottom to the top of the heat dissipation chamber 21. This airflow ensures that the water vapor and hot air generated by evaporation can be removed in time, preventing saturation or stagnation in the chamber, thereby maintaining a continuous driving force for evaporation and a heat dissipation effect.

[0047] The auxiliary system provided in this application stores the heavy coolant in a ground-level reservoir 20, avoiding the additional load and bending moment caused by placing a water tank on top of the mounting rod 2 or at a high location. This reduces the long-term fatigue risk of the rod structure and ensures the stability and safety of the installation structure. Simultaneously, the coolant is actively transported to the heat dissipation cavity 21 containing the heat-generating component (heat dissipation surface 10) via a liquid extraction device 3. The negative pressure environment created by the vacuum generator enhances evaporation and airflow guidance, ensuring that the evaporative cooling effect can directly and efficiently act on the core heat-generating area, overcoming the drawbacks of long distances and poor heat dissipation effects from ground-based liquid sources. The system constructs an active cycle of extraction, lifting, evaporation, and discharge. Compared to passive reliance on natural evaporation or infiltration, this cycle is controllable and reliable, its heat dissipation capacity is independent of ambient wind speed, and the enhanced evaporation efficiency through negative pressure results in significant and stable heat dissipation performance. Coolant replenishment, observation, and maintenance are all completed on the ground, eliminating the need to climb to higher locations and simplifying daily operation and maintenance.

[0048] In practice, the bottom of the liquid storage chamber 20 can be connected to an external water tank, so as to ensure that there is enough coolant in the liquid storage chamber 20 while avoiding excessive coolant in the liquid storage chamber 20, which would cause excessive load on the entire mounting rod 2.

[0049] According to some embodiments of this application, optionally, such as Figures 4-7 As shown, the lifting stroke of the liquid-collecting component 31 has a first limit position and a second limit position. When the liquid-collecting component 31 is in the first limit position, it is located in the heat dissipation cavity 21. When the liquid-collecting component 31 is in the second limit position, it is immersed in the coolant in the liquid storage cavity 20. The side wall of the heat dissipation cavity 21 is provided with a plurality of air inlets 211. In the height direction of the mounting rod 2, the heat dissipation surface 10 is located between the air inlets 211 and the air outlet 210. At least some of the air inlets 211 are arranged around the liquid-collecting component 31 in the first limit position.

[0050] In practical applications, the liquid-collecting component 31 is driven by the lifting mechanism 30, and its lifting stroke is precisely controlled, with a clear lower limit (second limit position) and upper limit (first limit position). When the liquid-collecting component 31 descends to the second limit position, its effective part is completely immersed in the coolant at the bottom of the liquid storage chamber 20, completing the full liquid collection. Subsequently, the lifting mechanism 30 drives the liquid-collecting component 31 to rise until it reaches the first limit position. At this time, the liquid-collecting component 31 is completely inserted into the internal space of the heat dissipation chamber 21, ready for evaporation and heat dissipation.

[0051] When the auxiliary system provided in this application is running, the vacuum generator operates, creating a suction force at the air outlet 210. Cooler, drier external air is drawn into the heat dissipation chamber 21 primarily through the lower-positioned air inlets 211. This airflow path is divided into two streams: one stream flows upwards, first passing over the heat dissipation surface 10 for direct air cooling; the other stream, particularly the air entering through the air inlets 211 surrounding the liquid-collecting component 31, directly blows onto or envelops the liquid-collecting component 31, which is just lifted from the ground and filled with coolant. The two streams eventually mix, carrying the heat absorbed from the heat dissipation surface 10 and the water vapor rapidly evaporating from the surface of the liquid-collecting component 31, and are drawn together by the negative pressure above, efficiently discharged from the air outlet 210.

[0052] By strategically positioning the air inlet 211, the heat dissipation surface 10, and the air outlet 210, a directional airflow path is created, with air entering from below and exiting from above. Cold air enters from below, naturally flowing first through the central heating element (heat dissipation surface 10) for initial heat exchange, before continuing to rise and carrying away moisture. This aligns with the physical principle of hot air rising, resulting in smooth airflow, low resistance, and high heat dissipation efficiency. By partially surrounding the liquid-collecting component 31 at the evaporation location with the air inlet 211, external air is directly guided to the coolant surface, providing ample fresh air for the evaporation process and enhancing the evaporation rate and heat absorption effect. This solves the problem of low evaporation efficiency when relying solely on static air within the cavity, achieving active air supply for the evaporative cooling process. After entering the heat dissipation cavity 21, part of the air directly cools the heat dissipation surface 10, while the other part enhances the evaporative cooling of the liquid-collecting component 31. The two airflows mix within the cavity before exiting, allowing a single airflow to complete two forms of heat dissipation tasks sequentially or simultaneously. This results in high system integration, synergistic heat dissipation capabilities, and superior performance compared to a single heat dissipation method.

[0053] In practice, some air inlets 211 (especially those surrounding the liquid dispensing component 31) can be adjustable in opening or closing. For example, when the humidity inside the heat dissipation cavity 21 is detected to be too high (insufficient evaporation), the opening area of ​​these air inlets 211 is automatically increased to enhance the airflow directly blowing onto the liquid dispensing component 31; when the ambient air is very humid, the air intake can be appropriately reduced, and the liquid dispensing frequency can be adjusted to achieve more intelligent humidity and heat dissipation management.

[0054] A filter, dust cover, or even a passive air-cooled fin assembly can be installed on the outside of the air inlet 211. The filter can prevent dust and insects from entering the heat dissipation chamber 21 and contaminating the equipment; the fin assembly can pre-cool the air before it enters, especially under intense sunlight, which can reduce the intake air temperature and further improve the overall heat dissipation effect.

[0055] According to some embodiments of this application, optionally, such as Figure 5 and Figure 7 As shown, the liquid-collecting component 31 includes a base 310 connected to the output end of the lifting mechanism 30, and a liquid-absorbing sponge 311 disposed on the base 310.

[0056] The absorbent sponge 311 mentioned in this application has the characteristics of high porosity and large pores, which allows the absorbed liquid to evaporate at a relatively fast rate.

[0057] In practical applications, when the lifting mechanism 30 drives the liquid-collecting component 31 to descend, the base 310, along with the liquid-absorbing sponge 311 on it, is immersed in the coolant in the liquid storage chamber 20. Through capillary action, the liquid-absorbing sponge 311 quickly and fully absorbs and stores a large amount of coolant, reaching saturation. Subsequently, the lifting mechanism 30 drives the liquid-collecting component 31 to rise to the first extreme position within the heat dissipation chamber 21. At this point, the liquid-absorbing sponge 311, loaded with coolant, is exposed to the airflow introduced by the air inlet 211 and guided by negative pressure. Due to the large internal surface area and open porous structure of the liquid-absorbing sponge 311, the coolant locked inside can continuously and evenly seep out and evaporate from its large surface. The airflow from the air inlet 211 (especially those surrounding the sponge 211) directly blows across the surface of the moistened liquid-absorbing sponge 311, accelerating the evaporation process and rapidly absorbing heat from the surrounding air.

[0058] The auxiliary system provided in this application uses absorbent sponge 311 as the liquid storage medium. It requires no additional pumps, valves, or precision metering devices; relying solely on the material's inherent properties, it automatically and quickly absorbs and stores coolant upon immersion, and securely locks the liquid during lifting, preventing leakage during transportation. This simplifies the auxiliary system structure while improving reliability. The porous structure of the absorbent sponge 311 not only stores the liquid but also creates a large effective surface area for evaporation within the heat dissipation chamber 21. Compared to smooth flat plates or containers, this structure allows the coolant to have greater contact with circulating air, enabling the evaporation and heat absorption process to release greater cooling power per unit time. The modular design of the base 310 and absorbent sponge 311 makes the liquid-collecting component 31 itself simple in structure and low in cost. As a consumable part, the sponge can be easily removed from the base 310 for replacement, cleaning, or dehydration (if the liquid carrying capacity needs adjustment), making maintenance convenient. This design also allows for easy adjustment of the sponge's volume, shape, or porosity according to heat dissipation requirements.

[0059] In practice, the absorbent sponge 311 can be designed with a specific windward shape (such as corrugated surface or fin shape) according to the airflow path of the air inlet 211 surrounding it, so that its structure can achieve optimal matching with the airflow field and maximize the heat exchange efficiency between the airflow and the wet surface.

[0060] According to some embodiments of this application, optionally, such as Figures 1-6As shown, the mounting rod 2 includes a first rod body 22 and a second rod body 23. The first rod body 22 is close to the ground, the air outlet 210 is located at the top of the second rod body 23, and the transmitter 1 is mounted on the second rod body 23. The first rod body 22 and the second rod body 23 are interconnected, and the top of the first rod body 22 extends into the inside of the second rod body 23. The inner wall of the part of the first rod body 22 located inside the second rod body 23 is provided with a partition 220. With the partition 220 as the boundary, the internal space of the part of the first rod body 22 facing the ground forms a liquid storage chamber 20, and the internal space of the part of the first rod body 22 facing away from the ground and the internal space of the second rod body 23 together form a heat dissipation chamber 21. An opening for the liquid-absorbing sponge 311 to pass through is opened in the center of the partition 220. When the liquid-taking component 31 is in the first extreme position, the liquid-absorbing sponge 311 passes through the partition 220 and extends into the heat dissipation chamber 21. In the height direction of the mounting rod 2, the liquid-absorbing sponge 311 extends beyond the first rod body 22.

[0061] The top of the first rod 22 and the second rod 23 can be positioned and connected by threads, flanges, locating pins or locking mechanisms to ensure that the two remain concentric during long-term use and under wind load.

[0062] There is an appropriate gap fit between the central opening of the partition 220 and the absorbent sponge 311.

[0063] In practical applications, the top of the first rod 22 extends upward and directly inserts into the internal space of the second rod 23, with the two communicating with each other in this area. A ring-shaped partition 220 (e.g., a horizontal partition or a conical ring) is fixedly installed on the inner wall of the portion of the first rod 22 that extends into the second rod 23. This partition 220 divides the internal space of the first rod 22 into two functional areas: the portion below the partition 220, facing the ground, forms the liquid storage chamber 20 for storing coolant; the portion above the partition 220, facing away from the ground (i.e., the upper section of the first rod 22), together with the internal space of the second rod 23 surrounding it, forms a heat chamber surrounding the upper section of the first rod 22. An opening is provided in the center of the partition 220. When the liquid-collecting component 31 (whose absorbent sponge 311 is attached to the base 310) is driven upward by the lifting mechanism 30, the absorbent sponge 311 will precisely pass through this opening. When the liquid-collecting component 31 reaches the first limit position, the liquid-absorbing sponge 311 completely passes through the partition 220, and its main body extends upward into the heat dissipation cavity 21 formed by the upper section of the first rod 22 and the second rod 23. In terms of vertical height, the upper end of the liquid-absorbing sponge 311 has exceeded the top of the first rod 22 itself and is placed in a wider space of the heat dissipation cavity 21 to facilitate evaporation.

[0064] The auxiliary system provided in this application integrates three major functions—liquid storage, heat dissipation, and support—into a single pole system. Through a nested pole-within-a-pole design, a stable liquid storage foundation is established near the ground, while the upper pole space is used to construct a heat dissipation duct, achieving seamless vertical integration and space reuse. The entire system appears as a single, compact pole, with a small footprint and high industrial integration. The partition 220 acts similarly to a valve floor. It isolates the liquid storage chamber 20 (wet zone) and the heat dissipation chamber 21 (dry zone), preventing excessive backflow of coolant vapor or accidental liquid entry into the heat dissipation chamber 21, which could interfere with the equipment. Simultaneously, its central opening provides a unique, controlled vertical channel for the liquid-absorbing sponge 311, ensuring that the liquid-receiving component 31 can move precisely between the two chambers with the shortest path and highest efficiency. Since the heat dissipation cavity 21 is formed by the annular space between the inner wall of the second rod 23 and the outer wall of the upper section of the first rod 22, when the airflow enters from the air inlet 211 on the side wall of the second rod 23, it will naturally form a flow around the upper section of the first rod 22 (where the absorbent sponge 311 is evaporating). This surrounding flow increases the contact area and contact time between the air and the moist absorbent sponge 311 and the heat dissipation surface 10 of the transmitter 1 installed on the outer wall of the second rod 23 (where heat is conducted through the rod wall or directly radiated), thus improving the overall heat exchange efficiency.

[0065] According to some embodiments of this application, optionally, such as Figure 5 As shown, when the liquid-collecting component 31 is in the first extreme position, the base 310 and the surface of the partition 220 facing the ground are pressed together to close the opening on the partition 220, so that the base 310, the partition 220 and the inner wall of the first rod 22 together form a tank structure for receiving the coolant flowing out from the liquid-absorbing sponge 311.

[0066] In practical application, when the lifting mechanism 30 drives the liquid-collecting component 31 to rise to the top of its stroke, i.e., the first extreme position, the top surface or edge of the base 310 of the liquid-collecting component 31, under the action of mechanical limiting, closely abuts against the surface of the partition 220 facing the ground (i.e., below). This action achieves a dual effect: First, the base 310 seals the opening in the center of the partition 220, cutting off the direct channel between the heat dissipation cavity 21 and the liquid storage cavity 20. Second, because the upper surface of the base 310 is in contact with the lower surface of the partition 220, and the gap between the side of the base 310 and the inner wall of the first rod 22 is very small, these three elements together temporarily form a bowl-shaped or ring-shaped trough structure at the top of the liquid storage cavity 20. During the heat dissipation stage, the liquid-absorbing sponge 311 located in the heat dissipation cavity 21 continuously evaporates the coolant. Some of the liquid coolant that does not evaporate in time or seeps out of the sponge due to gravity and saturation will flow downwards along the sponge. Because the opening below is sealed, the liquid does not drip directly back into the depths of the storage chamber 20, but is collected in the aforementioned tank structure. This tank serves as a temporary reservoir to receive and temporarily store this liquid.

[0067] The core effect of the auxiliary system provided in this application is to solve the problem of possible liquid leakage or ineffective backflow in the evaporative cooling system. It ensures that every drop of coolant lifted into the cooling chamber 21 is locked within the effective working area (either evaporating in the absorbent sponge 311 or temporarily stored in the receiving tank). This prevents the liquid from falling directly back to the bottom of the storage chamber 20 without sufficient evaporation, avoiding coolant waste and maximizing the utilization of coolant lifted each time. When the liquid-receiving component 31 is in the working position (i.e., the liquid-receiving component 31 is in the first extreme position), the sealing of the opening by the base 310 essentially isolates the cooling chamber 21 (negative pressure, high temperature, high humidity) from the storage chamber 20 (normal pressure, normal temperature). This helps maintain the stable negative pressure and airflow organization established by the vacuum generator within the cooling chamber 21, preventing it from being disturbed by air from the storage chamber 20; it also reduces the diffusion of hot and humid air from the cooling chamber 21 to the storage chamber 20, delaying the natural evaporation loss of the coolant and potential contamination. The free surface of the liquid stored within the formed tank structure is itself an evaporation surface. Although this surface is smaller than the surface area of ​​the absorbent sponge 311 and is located in a secondary position in the airflow path, it can still contribute some of the evaporative heat dissipation, constituting a beneficial supplementary heat dissipation mechanism. As the upper part of the absorbent sponge 311 gradually dries, the liquid in the tank may also be reabsorbed by the bottom of the sponge through capillary action, realizing the reuse of the liquid.

[0068] According to some embodiments of this application, optionally, such as Figure 5As shown, the lifting mechanism 30 includes a winch 300 and a traction rope 301. One end of the traction rope 301 is connected to the output end of the winch 300, and the other end is connected to the base 310. The traction rope 301 is elastic, and the winch 300 pulls the base 310 up and down by winding or releasing the traction rope 301. When the liquid picker 31 is in the first extreme position, the traction rope 301 pulls the base 310 and the partition 220 to keep them in a tight state under its own elasticity.

[0069] In practical applications, the traction rope 301 is made of an elastic material, such as a special rubber-core steel wire rope, a polyurethane core rope, or a similar elastic synthetic fiber rope with a certain elongation. The winch 300 can raise the base 310 and the liquid-absorbing sponge 311 by winding the traction rope 301 in a forward rotation, or lower them by releasing the traction rope 301 in a reverse rotation. When the winch 300 raises the liquid-collecting component 31 to the first limit position, the winch 300 stops and remains braked. At this time, the elastic traction rope 301, which is in a stretched state, will generate a continuous upward rebound force as it tends to contract and return to its original length. This force acts on the base 310, keeping it firmly pressed against the bottom surface of the partition 220, thereby reliably maintaining the closed state of the opening and the formation of the temporary trough structure.

[0070] The introduction of the elastic traction rope 301 is equivalent to adding an automatic tensioner to the abutment state between the base 310 and the partition 220. Even if the contact surfaces of the partition 220 or the base 310 deform or shift due to temperature changes, minor wear, or vibration during use, the continuous rebound force of the elastic rope can immediately compensate for this gap, adaptively maintaining sufficient sealing pressure. This is much more reliable than rigid connections or simple limiting methods, improving the sealing stability of the auxiliary system during long-term operation. The auxiliary system provided in this application uses a hoist 300 and traction rope 301 for lifting, which is simple in structure, technologically mature, and low in cost. At the same time, the elastic rope itself can buffer the impact and vibration during operation, protecting both the motor and the structure. Even in the event of a power outage, the self-locking braking function of the hoist 300 and the tension of the elastic rope can safely hold the liquid-receiving component 31 in its current position, preventing it from suddenly falling.

[0071] According to some embodiments of this application, optionally, a sealing element is provided at the edge of the surface of the base 310 facing the partition 220; when the liquid taking element 31 is in the first extreme position, the sealing element is located between the partition 220 and the base 310 to form a sealed connection.

[0072] The seals are made of water-resistant, temperature-resistant, and aging-resistant elastic materials, such as silicone rubber, fluororubber, or EPDM rubber.

[0073] In practical applications, when the lifting mechanism 30 drives the liquid-collecting component 31 to rise to the first extreme position, the base 310, along with its sealing component, moves upward together, eventually contacting and pressing against the lower surface of the partition 220. During this process, the soft sealing component is squeezed between the two relatively hard surfaces of the base 310 and the partition 220, undergoing elastic deformation to fill any microscopic gaps that may arise between them due to machining tolerances, surface roughness, or slight deformation. Thus, a reliable and tight sealing connection is formed around the central opening of the partition 220.

[0074] The seals ensure virtually no exchange of gas and moisture between the heat dissipation chamber 21 and the liquid storage chamber 20 during the heat dissipation phase. This maintains a stable negative pressure environment within the heat dissipation chamber 21, ensuring the efficiency of the vacuum generator and the controllability of airflow organization. It also effectively prevents hot, humid air from entering the liquid storage chamber 20, which could lead to unnecessary temperature rise or contamination of the coolant. The reliable sealing connection ensures the integrity of the temporary tank structure formed by the base 310, the partition 220, and the inner wall of the first rod 22. It prevents liquid collected in the tank from leaking back into the liquid storage chamber 20 through gaps in the contact surfaces or from improperly spreading along the gaps, further reducing ineffective liquid loss. The elastic seals have excellent following and compensation capabilities. Even if the system experiences thermal expansion and contraction of metal components due to temperature changes, or slight wear due to long-term use, the seals can continuously compensate for these changes through their elastic deformation, maintaining effective sealing force. This improves the reliability and maintenance-free cycle of the auxiliary system under different climatic conditions during long-term operation.

[0075] According to some embodiments of this application, optionally, such as Figure 1 , Figures 3-4 As shown, the transmitter 1 located outside the heat dissipation cavity 21 is also equipped with an exhaust fan 11. The exhaust fan 11 is used to draw outside air into the transmitter 1 and then send it into the heat dissipation cavity 21 through the heat dissipation port. The power of the vacuum generator is greater than the power of the exhaust fan 11.

[0076] In practical applications, the exhaust fan 11 is activated, drawing outside air into the transmitter 1. This air flows over the circuit boards, power modules, and other core heat-generating components, providing direct cooling. This air, having absorbed internal heat, is ultimately exhausted through the heat dissipation vents on the transmitter 1's casing and directly enters the heat dissipation chamber 21. Simultaneously, the vacuum generator located at the top of the heat dissipation chamber 21 operates continuously at a higher power. Because the power of the vacuum generator is greater than that of the exhaust fan 11, the suction force it creates at the top of the heat dissipation chamber 21 is always stronger than the air intake capacity of the exhaust fan 11. Therefore, a stable negative pressure environment is maintained throughout the entire heat dissipation chamber 21 (including the area near the transmitter 1's heat dissipation vents).

[0077] A new, active heat dissipation path has been added, achieving efficient synergy between internal air cooling and cavity evaporative cooling. The exhaust fan 11 is responsible for solving the heat accumulation problem inside the transmitter 1, directly transferring heat to the heat dissipation cavity 21; while the original system (vacuum generator and liquid extraction evaporation) is responsible for handling the overall heat load accumulated in the heat dissipation cavity 21. The combination of the two forms a comprehensive heat dissipation system from the inside out and from point to surface, with a heat dissipation effect superior to that of a single method.

[0078] According to some embodiments of this application, optionally, the field-type shortwave transmitter heat dissipation auxiliary system further includes a first sensor, a memory, and a control module. The first sensor is disposed on the base 310 and is used to detect the actual weight of the absorbent sponge 311. The memory is used to store a preset weight threshold of the absorbent sponge 311. The control module is configured to control the start and stop of the lifting mechanism 30 based on the comparison result between the actual weight detected by the first sensor and the preset weight threshold.

[0079] In practical applications, the control module continuously reads the weight data transmitted from the first sensor. The control logic is as follows: When the absorbent sponge 311 works in the heat dissipation cavity 21, the coolant continuously evaporates, and its total weight gradually decreases. The control module compares the actual weight with a preset weight threshold. Once the actual weight drops to equal to or below the preset weight threshold, the control module determines that the coolant in the sponge has evaporated to a level that needs to be replenished, and immediately issues a command to start the lifting mechanism 30. The lifting mechanism 30 then drives the liquid-collecting component 31 to descend, allowing the absorbent sponge 311 to immerse itself in the coolant in the liquid storage cavity 20 to re-absorb liquid. During the descent, immersion, and re-ascent of the liquid-collecting component 31, the control module can determine that liquid collection is complete based on a preset program or another weight threshold (such as an upper limit threshold representing sufficient liquid absorption), and control the lifting mechanism 30 to stop, raising the liquid-collecting component 31 back to the working position. Afterward, the auxiliary system re-enters the weight monitoring and comparison cycle.

[0080] By monitoring the actual weight of the absorbent sponge 311, the auxiliary system can directly sense the real-time status (liquid content) of the heat dissipation medium, thus precisely triggering the action at the moment when coolant replenishment is most needed. This avoids problems such as insufficient coolant intake (leading to heat dissipation interruption) or premature coolant intake (the sponge is still wet, wasting energy and potentially reducing airflow within the cavity) that may occur at fixed time intervals, ensuring that the heat dissipation process remains within the high-efficiency range and saving energy consumption of the lifting mechanism 30. The auxiliary system can automatically adapt to the influence of different environmental conditions (such as temperature, humidity, and wind speed) on the evaporation rate. When evaporation is rapid in dry and hot weather, the coolant intake frequency will automatically increase; when evaporation is slow in humid and cool weather, the coolant intake frequency will automatically decrease. This adaptive capability ensures the stability of the heat dissipation effect, reduces reliance on manual intervention, and improves operational reliability under all weather conditions.

[0081] According to some embodiments of this application, optionally, the field-type shortwave transmitter heat dissipation auxiliary system further includes a second sensor, a memory, and a control module. The second sensor is disposed in the heat dissipation cavity 21 and is used to detect the actual temperature of the heat dissipation cavity 21. The memory is used to store a preset temperature threshold of the heat dissipation cavity 21. The control module is configured to control the start and stop of the lifting mechanism 30 based on the comparison result between the actual temperature detected by the second sensor and the preset temperature threshold.

[0082] In practical applications, the control module continuously reads temperature data from the second sensor. When transmitter 1 generates heat, the temperature inside the heat dissipation cavity 21 rises. The control module compares the actual temperature with a preset temperature threshold. Once the actual temperature reaches or exceeds the preset temperature threshold, the control module determines that the current heat dissipation demand has increased and the evaporative cooling effect needs to be enhanced. It then immediately issues a command to activate the lifting mechanism 30. The lifting mechanism 30 then drives the liquid-collecting component 31 to descend and rise, replenishing the heat dissipation cavity 21 with fresh coolant. As the coolant evaporates and absorbs heat, the temperature of the heat dissipation cavity 21 begins to decrease. The control module continuously monitors the temperature. When the actual temperature drops below the preset temperature threshold by a certain range (i.e., a hysteresis interval is added to prevent frequent start-stop cycles), the control module stops the lifting mechanism 30. Afterward, the auxiliary system re-enters the temperature monitoring and comparison cycle.

[0083] When the power of transmitter 1 increases or the ambient temperature rises, causing a sudden increase in the cavity temperature, the auxiliary system can respond immediately by increasing the coolant supply to enhance heat dissipation, thereby directly and quickly preventing transmitter 1 from experiencing performance degradation or damage due to overheating. Unlike fixed-time or simple weight control, in low-load or cool environments, the heat dissipation requirement is low, and the system can remain stationary for extended periods, reducing unnecessary operation and mechanical wear of the lifting mechanism, achieving energy savings and extending component lifespan. Only when the heat load actually exists and reaches a certain level can the evaporative cooling resources be activated, ensuring a precise match between the auxiliary system's operation and heat dissipation requirements.

[0084] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
