Description

Technical Field

[0001] This utility model relates to grain air conditioners, and more particularly to an arc-shaped radiator structure for grain air conditioners. Background Technology

[0002] In this technical field, Chinese Patent Publication No. CN221992218U discloses a grain cooling unit, which mainly comprises a shell, an evaporator, a blower, and a water-blocking device. In this unit, the shell has an air inlet and an air outlet, the evaporator is arranged between the two, and the blower is located between the evaporator and the air outlet to deliver cool air. To prevent water mist from being blown out with the cool air, a water-blocking device is installed on the side of the evaporator near the blower. This device consists of multiple water-blocking plates with certain gaps, capable of covering the projected area on the side of the evaporator.

[0003] In the refrigeration system of the aforementioned grain cooling unit, the evaporator, expansion valve, condenser, and compressor work together. One end of the compressor is connected to the condenser, and the other end is connected to the evaporator. The condenser is connected to the evaporator via the expansion valve. The high-temperature refrigerant generated during compressor operation needs to be dissipated through the condenser. However, in this prior art solution, the condenser is mounted at the top of the casing and only located on the upper side of the casing. This results in a small heat dissipation area for the condenser, which limits the overall cooling performance of the unit. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a curved radiator structure for grain air conditioners to improve heat dissipation performance.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a grain air conditioner arc-shaped radiator structure, including a casing and a condenser. The casing has an air inlet, an air outlet, and a ventilation opening. An evaporator and a fan are connected inside the casing. The evaporator corresponds to the air inlet, the fan corresponds to the air outlet, and the condenser corresponds to the ventilation opening. A compressor is connected inside the casing. The compressor is connected to the condenser and the evaporator. The condenser is connected to the evaporator through an expansion valve. An auxiliary port is provided on the casing. The auxiliary port and the ventilation opening are located on two adjacent side walls of the casing. The ventilation opening, the air inlet, and the air outlet are all located on the same side of the casing. The condenser includes L-shaped heat sinks, a bracket, and copper pipes. The copper pipes are connected to the bracket. Multiple L-shaped heat sinks are connected to the copper pipes and arranged along the height direction of the bracket. One side of each L-shaped heat sink corresponds to the ventilation opening, and the other side corresponds to the auxiliary port.

[0006] To achieve the above technical solution, the compressor in the refrigeration system delivers high-temperature, high-pressure gaseous refrigerant to the condenser. The condenser employs an L-shaped heat sink structure, arranged using vents and auxiliary ports located on two adjacent side walls of the casing. When the refrigerant flows through the copper pipes connected to the L-shaped heat sink, its heat is conducted outward through the heat sink. Outside air can simultaneously flow across the surface of the L-shaped heat sink from both the vents and auxiliary ports, exchanging heat with the heat sink and thus condensing the refrigerant into a liquid state. Compared to traditional single-sided heat sinks, this significantly increases the effective heat dissipation area of ​​the condenser, improving space utilization. It also significantly enhances the heat exchange capacity of the condenser, improving the efficiency of the entire refrigeration cycle, thereby effectively improving the overall cooling performance of the grain-growing air conditioner.

[0007] As a preferred embodiment of this utility model, a partition is fixedly connected inside the housing, the partition dividing the housing into a left receiving cavity and a right receiving cavity, the air inlet and air outlet are connected to the left receiving cavity, and the ventilation port and auxiliary port are connected to the right receiving cavity.

[0008] To achieve the above technical solution, a partition is installed inside the casing to divide the internal space into two functionally independent accommodating chambers: a left accommodating chamber and a right accommodating chamber. The left accommodating chamber connects to the air inlet and outlet for processing grain air, forming a cooling air circulation loop. The right accommodating chamber connects to the ventilation opening and auxiliary opening for heat dissipation, forming a heat dissipation air exchange loop, and houses heat-generating components such as the condenser and compressor. This partition achieves physical isolation between the cooling system and the heat dissipation system. It effectively prevents the hot air generated in the right accommodating chamber from mixing with the cold air in the left accommodating chamber, avoiding the negative impact of thermal interference on the cooling effect.

[0009] As a preferred embodiment of this utility model, the housing is provided with an exhaust port, the exhaust port is connected to the right receiving cavity, an exhaust fan is connected to the exhaust port, and the exhaust port and the ventilation port are arranged opposite to each other.

[0010] To achieve the above technical solution, the exhaust fan located in the right-side condenser is activated, actively expelling air from the cavity through the exhaust vent. This creates a negative pressure within the right-side condenser, forcibly guiding outside cold air into the cavity through the correspondingly positioned vents and auxiliary openings. The incoming cold air flows at high speed over the surface of the L-shaped condenser, undergoing forced convection heat exchange, and is then exhausted by the exhaust fan carrying its heat. Compared to natural convection, this increases the air velocity and flow rate through the condenser, significantly enhancing heat exchange efficiency and further improving the unit's cooling capacity under high load or high temperature conditions.

[0011] In a preferred embodiment of this utility model, both the vent and the auxiliary vent are connected to a support frame, and a filter screen is connected inside the support frame.

[0012] To achieve the above technical solution, when outside air is drawn into the right-side cavity by the exhaust fan, it must first pass through filters installed on the vents and auxiliary openings. These filters, acting as physical barriers, intercept dust, impurities, insects, and other pollutants carried in the air, allowing only clean air to enter the cavity. This effectively prevents pollutants from adhering to or clogging the condenser's heat exchange fins, ensuring smooth airflow between the fins and maintaining long-lasting, high-efficiency heat exchange performance.

[0013] As a preferred embodiment of this utility model, an auxiliary fan is provided inside the housing, the auxiliary fan corresponds to the auxiliary port, and the air generated by the auxiliary fan blows through the compressor and is discharged by the exhaust fan.

[0014] To achieve the above technical solution, the heat dissipation system within the right-side housing cavity is driven collaboratively by an exhaust fan and an auxiliary fan. The exhaust fan primarily directs airflow across the side of the L-shaped heat sink corresponding to the vent; simultaneously, the auxiliary fan actively drives airflow across the other side of the L-shaped heat sink corresponding to the auxiliary vent. This ensures that both heat dissipation surfaces of the L-shaped heat sink receive active and robust airflow. After cooling the L-shaped heat sink, the airflow driven by the auxiliary fan continues to flow across the compressor surface for secondary cooling, finally merging with another airflow and being exhausted outside the housing by the exhaust fan. This ensures that both sides of the L-shaped heat sink receive forced air cooling, fully utilizing the large-area heat dissipation advantage of the L-shaped structure and maximizing the cooling efficiency of the condenser. Furthermore, the airflow after cooling the L-shaped heat sink is redirected again to cool the compressor, completing two key heat dissipation tasks with a single airflow volume.

[0015] In a preferred embodiment of this utility model, the outer casing of the auxiliary fan is rotatably connected to the bottom wall of the housing via an adjusting shaft, and a positioning bolt is threaded onto the outer casing of the auxiliary fan, the positioning bolt being used to abut against the bottom wall of the housing.

[0016] To achieve the above technical solution, the auxiliary fan simultaneously cools one side of the L-shaped heatsink and the compressor, making its installation angle crucial. Using the adjusting shaft and positioning bolts on its housing, the operator can easily rotate the auxiliary fan body and fix it at a specific angle. This adjustment process aims to find an optimal airflow configuration. This allows users to precisely adjust the auxiliary fan's airflow direction according to actual operating conditions to achieve the best balance between cooling the side of the L-shaped heatsink and the compressor.

[0017] As a preferred embodiment of this utility model, a protective frame is connected to the exhaust port of the housing, and the exhaust fan is located inside the protective frame.

[0018] Implementing the above technical solution can effectively prevent foreign objects from entering or personnel from accidentally touching the high-speed rotating fan blades, thus avoiding damage to the equipment itself and injury to the operators. Attached Figure Description

[0024] An auxiliary opening 6 is provided on the right side wall of the casing 1. The auxiliary opening 6 and the ventilation opening 4 are located on two adjacent side walls of the casing 1, while the ventilation opening 4, the air inlet 2 and the air outlet 3 are all located on the front side wall of the casing 1.

[0025] The condenser 7 includes L-shaped heat sinks 8, a bracket 9, and copper pipes 10. The copper pipes 10 are connected to the bracket 9, and the bracket 9 is fixed to the housing 1.

One side of the L-shaped heat sink 8 corresponds to the vent 4, and the other side of the L-shaped heat sink 8 corresponds to the auxiliary vent 6.

[0026] A partition 11 is fixedly connected inside the housing 1, dividing the housing 1 into a left receiving cavity 12 and a right receiving cavity 13. The air inlet 2 and the air outlet 3 are connected to the left receiving cavity 12, and the ventilation port 4 and the auxiliary port 6 are connected to the right receiving cavity 13. The compressor 24 and the condenser 7 are located in the right receiving cavity 13.

[0027] An exhaust vent 14 is provided on the housing 1, which communicates with the right receiving cavity 13. An exhaust fan 15 is connected to the exhaust vent 14. The exhaust vent 14 and the ventilation opening 4 are arranged opposite to each other, that is, the exhaust vent 14 is located on the rear side wall of the housing 1. A protective frame 16 is fixedly connected to the exhaust vent 14 of the housing 1, and the exhaust fan 15 is located inside the protective frame 16.

The filter screen 18 is made of nylon mesh with a mesh size of 40.

[0029] An auxiliary fan 19 is installed inside the casing 1, corresponding to the auxiliary port 6, and is located between the condenser 7 and the compressor 24. The air generated by the auxiliary fan 19 blows through the compressor 24 and is then discharged through the exhaust fan 15.

[0030] A support plate 20 is fixedly connected to the bottom wall of the housing 1. A connection hole 25 is provided on the support plate 20.

[0031] During operation, the interior is divided into two functionally independent cooling and heat dissipation zones by a partition 11. In the left receiving cavity 12, a fan drives air from the grain silo to enter through the air inlet 2, cools it through the evaporator 5, and then sends it back through the air outlet 3, forming a continuous grain cooling cycle. At the same time, in the right receiving cavity 13, the exhaust fan 15 located on the rear wall of the casing 1 starts, generating a strong suction force to forcefully guide outside cold air through the filters 18 on the front side wall vent 4 and the right side wall auxiliary port 6. The airflow entering the vent 4 flows laterally across the front heat dissipation surface of the L-shaped condenser 7; while the auxiliary fan 19 actively enhances the airflow entering from the auxiliary port 6, causing it to first flow across the right side heat dissipation surface of the L-shaped condenser 7, then blow over the surface of the compressor 24, and finally the two streams of hot air that have absorbed sufficient heat merge in the cavity and are forcefully discharged from the exhaust port 14 by the exhaust fan 15.

[0032] By coordinating the condenser 7 with the exhaust fan 15 and auxiliary fan 19, not only is the heat dissipation area maximized by utilizing the adjacent double side walls of the casing 1, but more importantly, it ensures that both heat dissipation surfaces of the L-shaped heat sink 8 receive active and powerful forced convection, completely solving the problems of uneven heat dissipation and low efficiency in traditional structures. Simultaneously, the auxiliary airflow provides secondary cooling to the compressor 24, achieving comprehensive and efficient heat management for the two core heat sources within the unit.
