Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, specifically to a vehicle-mounted mobile high-efficiency refrigeration device for agricultural products. Background Technology

[0002] Rapid cooling of agricultural products in or near the field after harvesting aims to quickly remove the "field heat" carried from the field and the continuous respiration heat, lowering the core temperature to a suitable low temperature in the shortest possible time. This technology is crucial because harvested agricultural products are still living organisms, continuously respiring and releasing heat. Without timely pre-cooling, high temperatures will accelerate moisture loss, nutrient depletion, softening, and aging, while also creating conditions for microbial growth, leading to accelerated spoilage. Rapid pre-cooling effectively inhibits the respiration intensity and enzyme activity of agricultural products, slowing down metabolism and preserving their original freshness, color, flavor, nutrition, and firmness to the greatest extent, significantly extending their post-harvest shelf life. Simultaneously, pre-cooling reduces the refrigeration load in subsequent cold chain processes, laying the foundation for efficient and energy-saving long-distance transportation and storage. It is a key step in ensuring the stable quality and minimizing losses of agricultural products from farm to table.

[0003] Chinese patent document CN216080510U discloses a differential pressure precooling box, including a box body with adjacent precooling chambers and a mechanical chamber inside. An insulation plate is provided between the precooling chambers and the mechanical chamber, and the insulation plate has an air intake and an air outlet, with the air outlet located above the air intake. The overall structural design of the box body is similar to that of a shipping container or cold chain transport box, facilitating loading and transportation. The precooling chambers are used to store agricultural products to be precooled. The differential pressure precooling box also includes a cold storage chamber, a centrifugal fan, a heat exchanger, and a liquid pump located within the mechanical chamber. The cold storage chamber is used to hold a predetermined amount of cold storage agent. Two cold storage chambers are arranged alternately on the left and right sides. The centrifugal fan is located between the two cold storage chambers, and is positioned along the front-to-back direction corresponding to the air intake. The heat exchanger is located between the centrifugal fan and the air outlet, and is situated above the cold storage chamber and the centrifugal fan. The liquid pump is used to transport the cold storage agent to the heat exchanger. The differential pressure precooling chamber also includes fans corresponding to the air outlets, which are typically axial flow fans of a predetermined specification. Of course, the mechanical chamber is also equipped with a corresponding power module (not shown), which drives the centrifugal fan, liquid pump, and fans. An air intake duct is formed between the two cold storage chambers. During actual operation, the centrifugal fan draws air from the precooling chamber into the air intake duct, and with the combined action of the fans, this air flows through the heat exchanger before being discharged from the air outlet, thus achieving cooling of the precooling chamber.

[0004] In the aforementioned technology, during the operation of the air-cooled condenser in the refrigeration system, if it is during the rainy season, rainy days, or in coastal areas, the dew point temperature of the air is high (i.e., the air already contains a large amount of water vapor). When the dew point temperature of the air flowing through the heat dissipation fins in the refrigeration system is higher than the surface temperature of the heat dissipation fins, the water vapor in the air undergoes a phase change and condenses into liquid water on the fin surface. This process is more pronounced when the ambient humidity is high and the refrigeration system operates efficiently, keeping the fin temperature at a low level. The long-term retention of condensate will cause multiple adverse consequences: First, the continuous contact between liquid water and the surface of the metal fins will accelerate the electrochemical corrosion and oxidation of the fins, directly damaging the core heat exchange element. Firstly, the structural integrity and service life of the components are affected. Secondly, the water film on the fin surface significantly alters the boundary layer state of airflow and increases airflow resistance, leading to a decrease in heat exchange efficiency. This forces the compressor to operate at a higher load to compensate for the efficiency loss, resulting in a decrease in the overall system energy efficiency ratio and an increase in energy consumption. Furthermore, static water provides an ideal environment for the growth of microorganisms (such as algae and mold), and their metabolic products and biofilms further exacerbate dirt adhesion and corrosion. At the same time, in the actual operating environment, the heat dissipation fins inevitably come into contact with suspended particles such as dust, willow catkins, and leaves. These impurities, along with condensate, adhere to the fin surface, all of which lead to a decrease in heat dissipation efficiency. Summary of the Invention

[0005] This invention provides a vehicle-mounted mobile high-efficiency refrigeration device for agricultural products, aiming to solve the problem in related technologies where condensation or debris on the surface of heat dissipation fins leads to a decrease in the heat dissipation efficiency of the fins.

[0006] A vehicle-mounted mobile high-efficiency refrigeration device for agricultural products includes two manifolds and multiple horizontal flat tubes arranged vertically between the two manifolds. A gap exists between two adjacent horizontal flat tubes, and a corrugated heat sink is installed within the gap. A fan is located on the left side of the heat sink. The device also includes: The dewatering mechanism includes an air collecting groove that is slidably installed on the front end face of the horizontal flat tube in the left-right direction and multiple air outlet pipes that are rotatably installed on the bottom of the air collecting groove. The air outlet pipes correspond one-to-one with the gaps. The air outlet pipes are used to guide the air in the air collecting groove to the heat sink. The air collecting groove is provided with a first driving component for driving the air outlet pipes to rotate. The rear end of the air outlet pipe is located in the gap. The collecting tube is provided with a second driving component for driving the air collecting groove to move. When the air collection slot drives the air outlet pipe to pass over the vertical surface of the heat sink, the air outlet pipe comes into contact with the heat sink and deflects. After the air outlet pipe passes over the vertical surface of the heat sink, the air outlet pipe quickly deflects in the opposite direction and strikes the heat sink in the direction of its deflection.

[0007] The dehydration mechanism, consisting of a drive unit and a collection trough, reciprocates linearly along the surface of the heat exchanger, achieving automatic full-coverage cleaning of the entire heat exchanger surface. During the movement, because the air outlet area of ​​the air outlet pipe inside the air collection trough is smaller than the air inlet area on the front of the air collection trough, the airflow enters the air collection trough and then enters the air outlet pipe, forming a high-pressure airflow. This high-pressure airflow is precisely guided to the surface of the heat sink through the air outlet pipe, and the airflow direction forms an acute angle with the surface of the heat sink, thus allowing the airflow to directly blow onto the surface of the heat sink and blow off the condensate. The cleaning action of the duct is a combination of deflection, rebound, and tapping. When the duct encounters the heat sink during its movement, it will be passively deflected. After passing the heat sink, it will quickly rebound under the action of the drive component and tap the heat sink behind it using the inertial force of the rebound. The cleaning method that combines blowing and tapping utilizes both the impact force of the airflow and the peeling force of mechanical vibration, which can effectively remove the attached condensate. Its cleaning effect is better than that of airflow blowing alone. Moreover, the whole process is automated and does not require shutdown, ensuring that the heat exchanger is always in operation.

[0008] Preferably, a collection trough is provided on the rear end face of the horizontal flow flat tube. The collection trough is used to collect condensate or dust blown down from the air outlet duct. A drain hole is provided at the lower end of the collection trough. The air collection trough is fixedly connected to the collection trough.

[0009] By setting up a collection tank, the condensate blown down from the heat sink by the air outlet pipe is prevented from accumulating around the entire device, thus preventing the fan from sucking in the condensate that has already been blown down and blowing it back onto the heat sink.

[0010] Preferably, the driving component one includes an elastic component one disposed between the air collecting duct and the air outlet duct, the elastic component one being used to make the air outlet duct perpendicular to the vertical plane.

[0011] By utilizing the energy storage and release characteristics of the elastic element, a power source is provided for the "deflection-rebound-striking" action of the air outlet duct. When the air outlet duct is deflected by the heat sink, the elastic element deforms and stores elastic energy. When the air outlet duct passes the obstruction of the heat sink, the stored elastic energy is released rapidly, driving the air outlet duct to produce a high-speed reverse deflection and striking action. This passive triggering structure does not require an additional control system and power source.

[0012] Preferably, the elastic element is a torsion spring, and the two ends of the torsion spring are respectively connected to the air collection groove and the air outlet pipe.

[0013] Because of the large number of heat sinks, torsion springs are used. The structure is simple and highly reliable, and it can provide stable torque so that the air duct can quickly return to its original position after deflection, ensuring the accuracy and repeatability of the tapping action.

[0014] Preferably, the second driving component includes a motor mounted on the collector pipe and a lead screw mounted on the output end of the motor. The lead screw passes through the air collecting groove, and the air collecting groove and the lead screw are threadedly engaged.

[0015] The rotary motion of the air collection trough is converted into linear movement by a screw driven by a motor, and the screw engagement converts the rotary motion into linear movement of the air collection trough, thus achieving precise positioning and reciprocating motion of the water removal mechanism. The screw drive has a self-locking characteristic, which ensures that the air collection trough can be stably stopped at any position and avoids accidental movement.

[0016] Preferably, the air collecting trough is completely covered by the projection of the collecting trough in the front-to-back direction.

[0017] This ensures that the air collection trough remains within the protection zone of the collection tank during movement, preventing condensate or dust from overflowing from the gap between the air collection trough and the horizontal flow flat pipe, thus improving collection efficiency.

[0018] Preferably, the right end of the air collection trough is provided with multiple cleaning rods for removing large dust particles, and the cleaning rods correspond one-to-one with the gaps.

[0019] The cleaning rod can remove large dust particles, such as willow catkins, leaves, and insect corpses, in advance during the movement of the air collection duct, preventing these impurities from clogging the air outlet duct or affecting the airflow distribution, thus improving the adaptability and reliability of the water removal mechanism.

[0020] Preferably, the collecting pipe is provided with a dust collection trough. When the right end of the air collecting trough moves into the dust collection trough, the cleaning rod pushes large pieces of dust into the dust collection trough. The lower end of the dust collection trough is provided with a dust discharge hole.

[0021] The dust collection trough is designed to collect large impurities. The large impurities are collected and processed by the pushing action of the cleaning rod, which prevents them from accumulating in the gaps between the heat sinks. At the same time, they can be easily discharged through the dust discharge hole.

[0022] Preferably, the right end face of the air collecting trough is provided with multiple through holes, and the cleaning rod is slidably installed in the through holes in the left and right direction. The left end of the cleaning rod is located in the air collecting trough, and the left end of the cleaning rod is provided with a ring platform for blocking the through holes. The air collecting trough is provided with a driving component three for moving the cleaning rod. When the air collecting trough moves to the rightmost end, its right end is located in the dust collecting trough, the cleaning rod moves to the left, and the ring platform disengages from the through holes. At this time, the air collecting trough and the dust collecting trough are connected through the through holes.

[0023] This structure enables the automatic extension and retraction of the cleaning rod and connects the air collection trough and the ash collection trough. When the air collection trough moves to the rightmost end, the drive unit pushes the cleaning rod to the left, causing the ring platform to disengage from the through hole. The airflow in the air collection trough can then enter the ash collection trough through the through hole, blowing large pieces of impurities accumulated on the cleaning rod into the ash collection trough, thus achieving centralized cleaning and discharge of large pieces of impurities.

[0024] Preferably, the driving component three includes an elastic component two disposed between the cleaning rod and the air collecting trough and a baffle one disposed on the cleaning rod. The baffle two is disposed in the ash collecting trough. The elastic component two is used to keep the ring platform in a state of blocking the through hole. When the air collecting trough just enters the ash collecting trough, the baffle one abuts against the baffle two.

[0025] The automatic control mechanism of the cleaning rod is realized through the cooperation of the elastic element 2 and the baffle. As the air collection trough gradually enters the dust collection trough, the baffle 1 and the baffle 2 are tightly abutted. This action effectively overcomes the resistance generated by the elastic element 2. During this process, the force of the baffle is transmitted to the cleaning rod, pushing it to move and eventually causing the through hole to be opened smoothly, so that the airflow can pass through the through hole to clean the right end of the cleaning rod.

[0026] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. The water removal mechanism adopts a coordinated design of air collection trough, air outlet duct, and collection trough. Combined with the deflection-rebound-tapping compound action of the air outlet duct, it realizes a dual cleaning mechanism of airflow purging and mechanical vibration. During the movement of the water removal mechanism, the air outlet duct deflects when it encounters the edge of the heat sink, changing the airflow direction, so that the high-pressure airflow directly impacts the surface of the heat sink at a sharp angle, effectively blowing off the attached condensate or dust. After the air outlet duct passes the heat sink, it quickly rebounds and taps the heat sink under the action of an elastic element (such as a torsion spring), generating vibration, further shaking off the condensate or dust. This compound cleaning method overcomes the problem of poor cleaning effect caused by the airflow direction being parallel to the surface of the heat sink in traditional airflow cleaning, and greatly improves the removal rate of condensate or dust. 2. The water removal mechanism achieves reciprocating linear motion along the surface of the heat exchanger through the second driving component (such as a motor and a lead screw). It can complete the full-coverage automatic cleaning without stopping the machine, ensuring the continuous and stable operation of the heat exchanger and improving the efficiency and reliability of the equipment. At the same time, the fixed connection design between the air collection trough and the collection trough ensures the integrity of dust collection. The collection trough can effectively collect the blown-off condensate or dust and discharge it through the drain hole, avoiding the accumulation of the removed condensate or dust around the device. 3. The dewatering mechanism is also equipped with a cleaning rod and a dust collection trough for pre-treatment and collection of large impurities (such as willow catkins, leaves, etc.). During its movement, the cleaning rod scoops up large dust particles in advance. With the cooperation of baffle one and baffle two, when the air collection trough moves into the dust collection trough, the cleaning rod moves to the left on the surface of the air collection trough, thereby causing the ring platform to disengage from the through hole and open the through hole. At this time, the interior of the air collection trough and the dust collection trough are connected through the through hole. Then, the airflow blows the impurities into the dust collection trough for centralized discharge, preventing impurities from clogging the gaps of the heat sink and further optimizing the dust removal effect.

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figures 1-11As shown in the figure, a vehicle-mounted mobile high-efficiency refrigeration device for agricultural products according to an embodiment of the present invention includes a housing 1, an evaporator 2, a condenser 3, a dehydration mechanism 4, a compressor 5, a fan 6, and a throttling device. The housing 1 can be placed on a vehicle for convenient use in the field, thereby cooling agricultural products in a timely manner. The housing 1 is divided into a pre-cooling compartment and an equipment compartment by a partition. The pre-cooling compartment is used to place agricultural products, and the equipment compartment is used to place the evaporator 2, condenser 3, dehydration mechanism 4, compressor 5, and throttling device. The dehydration mechanism 4 is installed on the condenser 3 to remove the water condensed on the surface of the condenser 3. The compressor 6... Low-temperature, low-pressure gaseous refrigerant is compressed into high-temperature, high-pressure gas and sent to condenser 3 to release heat to the outside and condense into high-pressure liquid. This liquid is throttled and depressurized by a throttling device (such as an expansion valve), transforming into a low-temperature, low-pressure vapor-liquid mixture. It then enters evaporator 2, where it absorbs heat from the surrounding air (or water) under low pressure and evaporates violently, transforming back into low-temperature, low-pressure gas, thereby significantly lowering the air temperature and cooling agricultural products. The refrigerant gas that has absorbed heat is drawn back into compressor 5, starting a new cycle. Fan 6 is located on the left side of condenser 3 to blow air and dissipate heat from condenser 3.

[0041] like Figures 1-11 As shown, the condenser 3 includes two vertically arranged manifolds 31, multiple horizontal flat tubes 32 arranged parallel between the two manifolds 31, multiple sets of heat exchange fins 33, and a water removal mechanism 4. The left and right ends of the horizontal flat tubes 32 are fixedly installed on the two manifolds 31, and the multiple horizontal flat tubes 32 are evenly distributed vertically between the two manifolds 31, with gaps between adjacent horizontal flat tubes 32. The heat exchange fins 33 are generally wavy, and multiple sets of heat exchange fins 33 are respectively arranged in multiple gaps. The upper and lower ends of the heat exchange fins 33 abut against the horizontal flat tubes 32 at their upper and lower ends, respectively, to conduct heat on the horizontal flat tubes 32, thereby improving the heat exchange area and efficiency.

[0042] The heat medium circulates inside the manifold 31 and the horizontal flat tube 32. At the same time, air flows laterally through the core structure formed by the horizontal flat tube 32 and the heat sink 33 under the strong drive of the fan 6. Efficient heat exchange occurs during this process. To ensure the removal of condensate from the heat exchanger surface, a water removal mechanism 4 is set between the two manifolds 31. The water removal mechanism 4 can reciprocate linearly along the surface of the heat exchanger, ensuring that the water removal mechanism 4 can achieve full coverage of the entire heat exchanger surface, thereby automatically completing the water removal work on the heat exchanger surface and ensuring the continuous and stable heat exchange efficiency.

[0043] like Figures 1-11As shown, the dewatering mechanism 4 includes an air collecting trough 41, multiple air outlet pipes 42, a collection trough 43, a driving component one, and a driving component two. The air collecting trough 41 is a long, narrow trough structure, and it is slidably mounted on the front end face of the horizontal flow flat pipe 32 in the left-right direction. An air inlet is opened on the front of the air collecting trough 41, and the air inlet is connected to an external air source for collecting and guiding airflow. Multiple air outlet pipes 42 are rotatably mounted at the rear end of the bottom of the air collecting trough 41. The number of air outlet pipes 42 is consistent with the number of gaps between the horizontal flow flat pipes 32, and the air outlet pipes 42 correspond one-to-one with the gaps. The rear end of the air outlet pipes 42 extends into the corresponding gaps to guide the air in the air collecting trough 41 to the heat sink 33. The collection trough 43 is a long, narrow trough structure. It is slidably installed on the rear end face of the horizontal flow flat tube 32 in the left-right direction to collect condensate or dust blown off the heat sink 33. The tops of the collection trough 43 and the air collection trough 41 both extend upwards, beyond the uppermost horizontal flow flat tube 32. The top of the collection trough 43 and the top of the air collection trough 41 are fixedly connected by a connecting plate. A sliding rod is also installed between the two collection tubes 31. The sliding rod passes through the connecting plate to support the air collection trough 41 and the collection trough 43. A driving component 1 is installed on the collection trough 43 to drive the air outlet tube 42 to rotate; a driving component 2 is installed on the collection tube 31 to drive the air collection trough 41 to move.

[0044] In actual operation, the second drive unit starts, causing the air collecting trough 41 to move in the left and right direction. The air collecting trough 41 is connected to an external air source (not shown in the figure). After the airflow enters the air collecting trough 41, it blows towards the heat sink 33 through the air outlet duct 42. When the air collecting trough 41 drives the air outlet duct 42 to pass over the vertical surface of the heat sink 33, the first drive unit controls the air outlet duct 42 to deflect first, so that it blows air towards the surface of the heat sink 33 in the deflection direction, blowing off the attached condensate. After the air outlet duct 42 passes over the vertical surface of the heat sink 33, the first drive unit controls the air outlet duct 42 to deflect quickly in the opposite direction and strike the heat sink 33 in the deflection direction, generating vibration, which further causes the condensate to fall off. The blown-off condensate is collected by the collection tank 43 and discharged through the drain hole at its lower end. The air collecting trough 41 is completely covered by the projection of the collection tank 43 in the front and back direction, ensuring the integrity of the condensate collection.

[0045] like Figure 5 As shown, the internal channel of the air collecting slot 41 gradually narrows from front to back, forming a constricted structure. Since the air outlet area of ​​the air outlet pipe 42 inside the air collecting slot 41 is smaller than the air inlet area on the front of the air collecting slot 41, the airflow enters the air collecting slot 41 and then enters the air outlet pipe 42, forming a high-pressure airflow. The high-pressure airflow is precisely guided to the surface of the heat sink 33 through the air outlet pipe 42, and the direction of the airflow is at an acute angle to the surface of the heat sink 33, making it easier to blow off the condensate on the surface of the heat sink 33.

[0046] like Figures 5-9As shown, the driving component includes an elastic element 44, which is a torsion spring. The two ends of the torsion spring are connected to the air collection slot 41 and the air outlet pipe 42, respectively. In its natural state, the torsion spring makes the air outlet pipe 42 perpendicular to the vertical plane.

[0047] As the air outlet duct 42 gradually approaches and eventually reaches the edge of the heat sink 33 during its movement, it first contacts and tightly abuts against the edge of the heat sink 33. Subsequently, as the air outlet duct 42 continues to move along the predetermined path, it will experience resistance from the heat sink 33, causing it to deflect. At the same time, the torsion spring connected to the air outlet duct 42 will deform under the influence of external force and gradually accumulate energy during the deformation process. When the air outlet duct 42 successfully passes the front end of the heat sink 33 it is abutting, the torsion spring that has accumulated energy will quickly release its stored energy, causing the air outlet duct 42 to deflect in the opposite direction at a relatively fast speed and finally strike the heat sink 33 in the direction of deflection. This striking action will cause the heat sink 33 to vibrate, which can effectively promote the shedding of condensate adhering to the heat sink 33, thereby improving the cleaning effect on the heat sink 33.

[0048] like Figures 2-4 As shown, the second driving component includes a motor 45 and a lead screw 46. The motor 45 is mounted on the manifold 31, and the lead screw 46 is connected to the output end of the motor 45 and passes through the air collection groove 41. The air collection groove 41 and the lead screw 46 are threadedly engaged. When the motor 45 rotates, it drives the lead screw 46 to rotate, thereby driving the air collection groove 41 to move in the left and right directions.

[0049] like Figures 3-7 As shown, multiple cleaning rods 47 are provided at the right end of the air collecting slot 41. Each cleaning rod 47 corresponds to a gap, and the cleaning rod 47 forms an acute angle with the vertical plane. The front end of the horizontal flow tube 32 extends beyond the front end of the heat sink 33. The right end of the cleaning rod 47 extends into the gap, and the right end of the cleaning rod 47 is located between the front end of the horizontal flow tube 32 and the front end of the heat sink 33. A dust collection trough 48 is provided on the right end of the air collecting slot 31. When the air collecting slot 41 moves to the rightmost end, the cleaning rods 47 push large pieces of dust into the dust collection trough. Inside 48, the lower end of the dust collection trough 48 is provided with a dust discharge hole 481 for discharging large pieces of dust. The cleaning rod 47 can scoop up large pieces of dust from the front end of the heat sink 33 in advance during the movement of the air collection trough 41, such as willow catkins, leaves, insect corpses, etc. Since the cleaning rod 47 forms an acute angle with the vertical plane, the large pieces of dust that are scooped up will be guided by the cleaning rod 47 to move forward, thereby preventing these impurities from being pressed into the gaps between the heat sinks 33 and avoiding clogging the gaps between the heat sinks 33.

[0050] like Figures 3-7As shown, multiple through holes are provided on the right end face of the air collection trough 41. The cleaning rod 47 is slidably installed in the through holes in the left and right directions. The left end of the cleaning rod 47 is located in the air collection trough 41, and a ring platform 471 is provided on the left end for blocking the through holes. A driving component 3 is provided on the air collection trough 41 to move the cleaning rod 47 in the left and right directions.

[0051] As the right end of the air collecting trough 41 gradually extends into the ash collecting trough 48, the edge of the air collecting trough 41 forms a tight seal on the left end of the ash collecting trough 48. In this way, the internal space of the ash collecting trough 48 can only communicate with the external environment through the ash discharge hole 481 at its lower end. Just as the right end of the air collecting trough 41 completes the sealing action on the left end of the ash collecting trough 48, the drive unit 3 will immediately start, driving the cleaning rod 47 to move to the left. This movement process allows the ring platform 471 on the cleaning rod 47 to smoothly disengage from the original through hole. At this time, the internal spaces of the air collecting trough 41 and the ash collecting trough 48 are interconnected through this through hole. Subsequently, the airflow inside the air collecting trough 41 can smoothly enter the interior of the ash collecting trough 48 through this newly formed channel. During this process, the airflow carries enough force to effectively blow away large impurities accumulated on the surface of the cleaning rod 47, causing them to fall into the bottom of the ash collection trough 48 and be smoothly discharged to the outside through the ash discharge hole 481 at the lower end of the ash collection trough 48, thus achieving the centralized cleaning and discharge of large impurities.

[0052] The driving component three includes an elastic element 472, multiple baffles 473, and a baffle 482. The baffle 482 is installed inside the dust collection trough 48. The elastic element 472 is a spring, and its two ends are connected to the ring platform 471 and the air collection trough 41, respectively, to keep the ring platform 471 in a blocked state. The multiple baffles 473 are respectively installed at the right ends of the multiple cleaning rods 47.

[0053] As the right end of the air collecting trough 41 begins to enter the interior space of the dust collecting trough 48, the first baffle 473 and the second baffle 482 abut against each other tightly. As the air collecting trough 41 continues to move to the right in the predetermined direction, the second baffle 482 begins to function, pushing the cleaning rod 47 to move to the left on the surface of the air collecting trough 41. During this process, the ring platform 471 gradually disengages from the originally nested through hole. At this time, the interior of the air collecting trough 41 and the dust collecting trough 48 are connected through the through hole. The airflow and dust inside the air collecting trough 41 can smoothly enter the dust collecting trough 48 through the through hole. During this process, the strong airflow inside the air collecting trough 41 will effectively blow away the large impurities accumulated on the cleaning rod 47, causing them to fall into the interior of the dust collecting trough 48, thereby achieving centralized cleaning and efficient discharge of large impurities, ensuring the smooth operation of the system and the cleanliness of the environment.

[0054] like Figure 4As shown, a baffle 3 49 is provided on the right end of the collecting pipe 31. When the right end of the collecting duct 41 enters the dust collecting trough 48, the baffle 3 49 abuts against the rear end of the outlet pipe 42, thereby blocking the outlet of the outlet pipe 42. This allows the airflow in the collecting duct 41 to enter the dust collecting trough 48 only through the through hole, concentrating the airflow to clean the large dust particles pushed into the dust collecting trough 48 by the cleaning rod 47.

[0055] The working process of the vehicle-mounted mobile high-efficiency refrigeration device for agricultural products of the present invention is as follows: In the initial state, the dehydration mechanism 4 is positioned on the left side of the heat exchanger. When the motor 45 is started, it begins to run and drives the lead screw 46 to rotate. This rotation causes the air collecting trough 41 to move to the right along a predetermined track. As the air collecting trough 41 moves to the right, the airflow inside it is forcefully blown onto the surface of the heat sink 33 through the air outlet duct 42. During this process, when the movement path of the air outlet duct 42 encounters the edge of the heat sink 33, the air outlet duct 42 will deflect accordingly. This deflection changes the relative angle between the airflow blown out by the air outlet duct 42 and the heat sink 33, so that the direction of the airflow forms an acute angle with the surface of the heat sink 33. This angle setting is more conducive to effectively blowing off the condensate adhering to the surface of the heat sink 33. At the same time, the torsion spring connected to the air outlet duct 42 will also deform accordingly due to the action of external force, and gradually accumulate energy during the deformation process. When the air outlet duct 42 successfully crosses the edge of the heat sink 33, the torsion spring that has accumulated energy will quickly release its stored energy, causing the air outlet duct 42 to deflect in the opposite direction at a relatively fast speed, and finally strike the heat sink 33 in the direction of deflection. This striking action will cause the heat sink 33 to vibrate, and the vibration can effectively promote the condensate adhering to the heat sink 33 to fall off, thereby improving the cleaning effect on the heat sink 33.

[0056] As the right end of the air collecting trough 41 extends further into the dust collecting trough 48, the first baffle 473 and the second baffle 482 come into tight contact. As the air collecting trough 41 continues to move to the right, the second baffle 482 applies a thrust to the cleaning rod 47, causing it to move to the left on the air collecting trough 41. This movement allows the ring platform 471 to smoothly disengage from its original through-hole. At this point, the interiors of the air collecting trough 41 and the dust collecting trough 48 are connected through the through-hole, allowing airflow and dust from the air collecting trough 41 to enter the dust collecting trough 48. During this process, large pieces of impurities accumulated on the cleaning rod 47 are also blown off by the strong airflow and enter the dust collecting trough 48, thus achieving centralized cleaning and efficient discharge of large impurities. At the same time, the baffle 3 49 is tightly abutted against the rear end of the air outlet 42. This action effectively blocks the air outlet of the air outlet 42, so that the airflow in the air collection groove 41 can only enter the dust collection groove 48 through the through hole, and the concentrated airflow thoroughly cleans the large dust particles pushed into the dust collection groove 48 by the cleaning rod 47.

[0057] After the dewatering work on the right side is completed, the motor 45 reverses its drive, causing the air collection trough 41 to move to the left. At this time, the dewatering process of the air outlet duct 42 will be repeated to ensure that the condensate on the entire surface of the heat exchanger is completely and effectively removed.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
