Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically a high-temperature, high-load variable displacement compressor with a heat dissipation structure. Background Technology

[0002] High-temperature, high-load variable displacement compressors are compressors that can operate stably under high-temperature and high-load conditions. They are mainly used in automotive air conditioning, industrial refrigeration, and special cooling systems.

[0003] In high-temperature, high-load operating environments, the cylinder of a variable displacement compressor is prone to accumulating a large amount of heat due to continuous operation. If heat dissipation is not timely, it can lead to decreased equipment efficiency, shortened service life, or even malfunction. Traditional compressors often employ simple fin designs for heat dissipation, with insufficient and unevenly distributed fins, making it difficult to form efficient heat dissipation channels. Furthermore, the lack of effective connections and reinforcement between fins not only affects structural stability but also reduces heat dissipation efficiency due to airflow disturbances. In addition, conventional fin surfaces lack special structural designs, resulting in limited heat exchange area, and poor airflow between adjacent fins further restricts heat dissipation, failing to meet the heat dissipation requirements under high-temperature, high-load conditions.

[0004] Therefore, a high-temperature, high-load variable displacement compressor with a heat dissipation structure was proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a high-temperature, high-load variable displacement compressor with a heat dissipation structure to solve the problems mentioned in the background art. In the current high-temperature, high-load working environment, the cylinder of the variable displacement compressor has problems such as insufficient number of fins, uneven distribution, lack of reinforcement leading to poor stability and airflow disturbance, limited heat exchange area due to the lack of special surface design, and poor airflow. As a result, the heat dissipation is not timely, which can easily lead to a decrease in equipment efficiency, a shortened lifespan, or even failure, and cannot meet the heat dissipation requirements of this working condition.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature, high-load variable displacement compressor with a heat dissipation structure, comprising a cylinder, a clutch, and a rear cover, wherein the clutch is drivenly connected to the cylinder via a main shaft, and the rear cover is fixedly connected to the end of the cylinder away from the clutch, characterized in that: Several heat dissipation fins are fixedly connected to the outer sides of the cylinder body and the rear cover, and the heat dissipation fins are evenly distributed radially around the cylinder body. Adjacent heat dissipation fins are fixedly connected by reinforcing ribs; The heat dissipation fins are provided with at least one row of heat dissipation areas and micropores formed in the heat dissipation areas; Several heat dissipation grooves are provided on the reinforcing rib.

[0007] Preferably, the heat dissipation areas on the heat dissipation fins are arranged in multiple rows, with the micropores in adjacent rows being staggered, and the heat dissipation areas are distributed along the length of the heat dissipation fins.

[0008] Preferably, the diameters of the micropores in adjacent rows of heat dissipation areas are different, with the diameter of the micropores farther from the cylinder body being larger than the diameter of the micropores closer to the cylinder body.

[0009] Preferably, the cross-section of the heat dissipation groove is a triangle with an opening on one side.

[0010] Preferably, the heat dissipation groove gradually decreases in size from the side furthest from the cylinder body to the side closest to the cylinder body.

[0011] Preferably, the projected area of ​​the micropores on the heat sink fins is no more than 20% of the area of ​​the heat sink fins.

[0012] Preferably, the projected area of ​​the heat dissipation grooves on the reinforcing rib is no more than 5% of the projected area of ​​the reinforcing rib.

[0013] Preferably, the heat dissipation fins are integrally formed with the cylinder body or are fixedly connected by welding.

[0014] Preferably, the reinforcing rib is integrally formed with the adjacent heat dissipation fins.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-temperature, high-load variable displacement compressor with a heat dissipation structure constructs a "fin + micropore + heat dissipation groove" heat dissipation system by setting specially designed heat dissipation fins on the outer side of the compressor cylinder and rear cover to improve heat dissipation efficiency and adapt to high-temperature, high-load operating conditions. At the same time, the integral molding of reinforcing ribs and fins and the control of the projected area of ​​micropores and heat dissipation grooves ensure structural stability. Furthermore, the integral molding or welding connection of fins and cylinder and the integral molding of reinforcing ribs and fins optimize production and assembly to improve practicality and economy. The specific details are as follows: Firstly, it improves heat dissipation efficiency to meet the demands of high-temperature and high-load operating conditions: This invention features several heat dissipation fins evenly distributed radially along the cylinder body and the outer side of the rear cover. The fin structure significantly increases the contact area between the compressor and the outside air. Compared to a finless design, the heat dissipation fins improve heat dissipation efficiency, effectively solving the problem of excessively high temperatures in the cylinder body and rear cover due to heat accumulation under high-temperature and high-load conditions. This prevents internal compressor components from aging or degrading due to high temperatures, ensuring stable operation of the compressor under long-term high-temperature environments. The heat dissipation fins have at least one row of heat dissipation areas and micro-holes. The micro-holes reduce the thermal resistance of the fins themselves and guide airflow through the fin gaps, forming an efficient convection heat dissipation channel and accelerating heat dissipation. When there are multiple rows of heat dissipation areas, adjacent rows of micro-holes are staggered, further disrupting the airflow path and preventing "dead zones" from forming in the fin gaps, resulting in more uniform heat dissipation. Compared to a design with aligned micro-holes in the same row, the heat dissipation is more uniform. Several heat dissipation slots are formed on the reinforcing ribs between adjacent heat dissipation fins. These slots not only help to guide airflow between the fins but also reduce heat accumulation on the reinforcing ribs themselves, preventing heat conduction by the ribs from affecting heat dissipation. This forms a heat dissipation system of "fins + micropores + heat dissipation slots," comprehensively improving heat dissipation efficiency and meeting the stringent heat dissipation requirements of high-temperature, high-load variable displacement compressors. In adjacent rows of heat dissipation areas, the diameter of the micropores farther from the cylinder is larger than that closer to the cylinder. This design fully considers the principle that the cylinder is the main heat source and heat gradually decreases from the cylinder to the fin tip: the smaller diameter micropores closer to the cylinder can maintain the structural strength of the fins while ensuring heat dissipation; the larger diameter micropores farther from the cylinder can accelerate the discharge of heat from the tip through a larger airflow channel, achieving a precise fit of "strong structure near the cylinder and strong heat dissipation far from the cylinder." The heat dissipation slots gradually decrease in size from the side furthest from the cylinder to the side closest to the cylinder, and the cross-section is a triangle with one side open. This structure is consistent with the gradient of heat diffusion from the cylinder outward. The small slots close to the cylinder can reduce the impact on the strength of the reinforcing ribs, while the large slots far from the cylinder can enhance the airflow guidance capacity, achieving an optimal balance between heat dissipation and structural stability. Secondly, to ensure structural stability and extend compressor lifespan: adjacent heat dissipation fins are fixedly connected by reinforcing ribs. These ribs effectively enhance the connection strength between fins, preventing fin deformation and breakage due to vibration or airflow impact under high-temperature and high-load conditions. Compared to fin structures without reinforcing ribs, this design improves fin deformation resistance. Furthermore, the reinforcing ribs are integrally formed with adjacent heat dissipation fins, further eliminating connection gaps and preventing structural weaknesses caused by welding or assembly gaps, ensuring long-term stable and reliable heat dissipation. The projected area of ​​micropores on the heat dissipation fins does not exceed 20% of the fin area. This proportion maximizes heat dissipation while strictly controlling the fin perforation rate, preventing a decrease in fin strength due to excessive micropores and ensuring the fins are not easily damaged under high-load and vibration environments. The projected area of ​​heat dissipation grooves on the reinforcing ribs does not exceed 5% of the reinforcing rib's projected area. While providing auxiliary heat dissipation, this design maximizes the support cross-section of the reinforcing ribs, ensuring their reinforcement of the fins and preventing excessive heat dissipation grooves from affecting structural stability, thus achieving a dual guarantee of "heat dissipation performance" and "structural strength." Finally, optimizing production and assembly enhances practicality and economy: The heat dissipation fins can be integrally molded with the cylinder or fixedly connected by welding. Integral molding reduces assembly steps, minimizes production errors, and improves the thermal conductivity of the heat dissipation fins and cylinder, making it suitable for mass standardized production. Welding allows for flexible adaptation to different cylinder and fin specifications, reducing mold costs and meeting customized production needs. These two connection methods provide manufacturers with diverse options, improving product adaptability. The reinforcing ribs are integrally molded with adjacent heat dissipation fins, eliminating the need for additional assembly or welding. This not only reduces production steps but also prevents malfunctions caused by loose or corroded connecting parts during later use, lowering compressor maintenance frequency and costs, and extending the overall product lifespan.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figure 1-3 As shown, the high-temperature, high-load variable displacement compressor with a heat dissipation structure provided by this utility model mainly consists of a cylinder body 1, a clutch 2, and a rear cover 3, which form the core transmission and sealing structure. The clutch 2 is connected to the cylinder body 1 via a main shaft, ensuring stable power transmission to the compression components inside the cylinder body. The rear cover 3 is fixedly connected to the end of the cylinder body 1 away from the clutch 2, forming a sealed protection for the internal working chamber of the cylinder body, ensuring the normal operation of the compressor under high-temperature and high-load conditions. like Figure 1 As shown, to enhance the heat dissipation effect of the cylinder body 1 and the rear cover 3, several heat dissipation fins 4 are fixedly connected to the outer side of both the cylinder body 1 and the rear cover 3. The heat dissipation fins 4 are evenly distributed radially around the cylinder body 1. This distribution method can ensure the uniformity of heat dissipation in the circumferential direction of the cylinder body 1 and avoid the problem of temperature concentration caused by poor local heat dissipation. Regarding the connection method between the heat dissipation fins 4 and the cylinder 1, two preferred solutions can be adopted: one is that the heat dissipation fins 4 and the cylinder 1 are integrally formed. This method can ensure the structural stability and heat conduction efficiency between the heat dissipation fins 4 and the cylinder (1) and reduce the contact thermal resistance during the heat transfer process; the other is that the heat dissipation fins 4 are fixedly connected to the cylinder 1 by welding. The number and size of the heat dissipation fins 4 can be flexibly adjusted according to the actual production needs, and the connection strength can meet the usage requirements under high temperature and high load conditions. The connection method of the heat dissipation fins 4 on the outside of the rear cover 3 can be implemented with reference to the connection method of the cylinder 1. like Figure 2 As shown, in the specific structure of the heat dissipation fin 4, at least one row of heat dissipation areas is formed on it, and each heat dissipation area is provided with a number of micro-holes 401. The arrangement of micro-holes 401 can increase the contact area between the heat dissipation fin 4 and the air without significantly reducing the structural strength of the heat dissipation fin 4, and at the same time promote the flow of air on the surface of the heat dissipation fin 4, thereby improving the convective heat dissipation efficiency. Furthermore, to optimize heat dissipation, the heat dissipation areas on the heat dissipation fins 4 can be arranged in multiple rows, with these rows distributed sequentially along the length of the heat dissipation fins 4. The micro-holes 401 in adjacent rows of heat dissipation areas are staggered. This design prevents airflow from being "short-circuited" due to the alignment of the micro-holes 401 during airflow, extending the residence time of air on the surface of the heat dissipation fins 4 and allowing for sufficient heat exchange between the air and the heat dissipation fins 4. Simultaneously, the diameters of the micro-holes 401 in adjacent rows of heat dissipation areas can be set to different sizes, following the principle that "the diameter of the micro-holes 401 farther from the cylinder 1 is larger than the diameter of the micro-holes 401 closer to the cylinder 1." Since the temperature is higher in the area closer to the cylinder 1, the smaller diameter micro-holes 401 can form a denser heat dissipation point in this area, enhancing local heat dissipation; while the temperature is relatively lower in the area farther from the cylinder 1, the larger diameter micro-holes 401 can reduce airflow resistance and improve overall heat dissipation efficiency while ensuring heat dissipation performance. The projected area of ​​the micro-holes 401 on the heat sink fins 4 must be strictly controlled and should not exceed 20% of the area of ​​the heat sink fins 4. This design parameter is determined by comprehensively considering the optimal choice between heat dissipation efficiency and structural strength: if the projected area of ​​the micro-holes 401 is too high, the structural strength of the heat sink fins 4 will decrease and it will be unable to withstand the vibration and stress under high temperature and high load conditions; if the proportion is too low, the role of the micro-holes 401 in increasing the heat dissipation area cannot be fully utilized, and it will be difficult to meet the heat dissipation requirements. like Figure 1 As shown, to improve the structural stability of the heat dissipation fins 4 and prevent them from deforming or breaking due to vibration or thermal stress under high temperature and high load conditions, reinforcing ribs 5 are used to fix adjacent heat dissipation fins 4 together. Preferably, the reinforcing ribs 5 and adjacent heat dissipation fins 4 are integrally formed. This method can ensure the connection strength between the reinforcing ribs 5 and the heat dissipation fins 4, while reducing the thermal resistance caused by assembly gaps, ensuring that heat can be transferred between adjacent heat dissipation fins 4 through the reinforcing ribs 5, and further optimizing the uniformity of heat dissipation. like Figure 3As shown, the reinforcing rib 5 has several heat dissipation slots 501 in its structural design. The heat dissipation slots 501 are designed to prevent the reinforcing rib 5 from obstructing the airflow between the heat dissipation fins 4, while increasing the heat dissipation area of ​​the reinforcing rib 5 itself. Specifically, the cross-section of the heat dissipation slot 501 is designed as a triangle with one open side. The triangular cross-section of the heat dissipation slot 501 can not only maximize the heat dissipation area, but also guide the airflow along the inclined surface of the heat dissipation slot 501, reducing airflow resistance. At the same time, the heat dissipation slot 501 gradually decreases in size from the side away from the cylinder 1 to the side closer to the cylinder 1. This gradual structure is adapted to the temperature distribution of the cylinder 1. The area closer to the cylinder 1 has a higher temperature, and the smaller heat dissipation slot 501 can ensure the structural strength of the reinforcing rib 5 in the high-temperature area while ensuring airflow. The area away from the cylinder 1 has a lower temperature, and the larger heat dissipation slot 501 can further improve the airflow efficiency and enhance the overall heat dissipation effect. Similar to the design of the micro-hole 401, the projected area of ​​the heat dissipation slot 501 on the reinforcing rib 5 also needs to be strictly controlled and should not exceed 5% of the projected area of ​​the reinforcing rib 5. The core purpose of this parameter setting is to optimize the heat dissipation function while ensuring the structural support of the reinforcing rib 5: if the projected area of ​​the heat dissipation slot 501 is too high, it will weaken the support strength of the reinforcing rib 5 and will not be able to effectively fix the heat dissipation fins 4; if the proportion is too low, it will be difficult to guide airflow and improve heat dissipation, thus losing the design significance of opening the heat dissipation slot 501. Working principle: Before using this high-temperature, high-load variable displacement compressor with a heat dissipation structure, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 3 As shown, when the compressor starts, the clutch 2 drives the internal components of the cylinder 1 to rotate via the main shaft. During this process, the compression of the refrigerant inside the cylinder 1 accumulates a large amount of heat. This heat is first conducted through the metal wall of the cylinder 1, and some of the heat is directly transferred to the outside of the cylinder 1. At the same time, the rear cover 3, which is fixedly connected to the end of the cylinder 1 away from the clutch 2, receives the heat conducted by the cylinder 1 through the contact surface with the cylinder 1, forming heat accumulation on the surface of the rear cover 3. At this time, the cylinder 1 and the rear cover 3 become the main heat source areas of the compressor. To expand the heat dissipation area, several heat dissipation fins 4 are fixedly connected to the outer sides of both the cylinder body 1 and the rear cover 3, and the heat dissipation fins 4 are evenly distributed radially around the cylinder body 1. When the heat from the surface of the cylinder body 1 and the rear cover 3 is transferred to the heat dissipation fins 4, the heat dissipation fins 4, with their large surface area, disperse the concentrated heat to each fin unit. Then, through air convection, the heat on the fin surface is transferred to the surrounding environment, completing the first round of heat dissipation. Meanwhile, the heat dissipation fins 4 have at least one row of heat dissipation areas and micropores 401 located in the heat dissipation areas. These micropores 401 further increase the contact area between the heat dissipation fins 4 and the air without reducing the structural strength of the fins. They can also guide the air to form turbulence inside the fins, break the air boundary layer on the surface of the fins, reduce thermal resistance, and accelerate the efficiency of heat transfer from the fins to the air. The heat dissipation area on the heat dissipation fins 4 consists of multiple rows, with the micro-holes 401 in adjacent rows staggered and distributed along the length of the heat dissipation fins 4. This staggered structure avoids the "airflow short-circuit" phenomenon when air flows through the multiple rows of micro-holes 401, ensuring that the air can fully contact the fin area around each row of micro-holes 401, maximizing the use of the fin surface area for heat dissipation. In addition, when the diameters of the micro-holes 401 in adjacent rows of heat dissipation areas are different, and the diameter of the micro-holes 401 farther from the cylinder 1 is larger than that of the micro-holes 401 closer to the cylinder 1, the fin area closer to the cylinder 1 receives more concentrated heat and has a higher temperature. The smaller diameter micro-holes 401 can form a denser airflow channel in this area, enhancing the local heat dissipation intensity. Meanwhile, the temperature of the fin area farther from the cylinder 1 is relatively lower, and the larger diameter micro-holes 401 can reduce airflow resistance while ensuring heat dissipation effect, achieving a balance between heat dissipation efficiency and airflow resistance. In addition, the projected area of ​​the micropores 401 on the heat dissipation fins 4 is no more than 20% of the area of ​​the heat dissipation fins 4. This design can improve the heat dissipation effect while ensuring that the heat dissipation fins 4 retain sufficient structural strength, avoid the fins from being easily broken or deformed due to too many micropores 401, and ensure the long-term stability of the heat dissipation structure. To prevent adjacent heat dissipation fins 4 from deforming or shifting in spacing under long-term high temperature and high load conditions, adjacent heat dissipation fins 4 are fixedly connected by reinforcing ribs 5. The reinforcing ribs 5 can support and position the heat dissipation fins 4, improving the rigidity of the entire heat dissipation structure. On the other hand, the reinforcing ribs 5 are in direct contact with the heat dissipation fins 4, which can receive some of the heat conducted by the heat dissipation fins 4 and diffuse it into the air through their own surface, further increasing the heat dissipation path. Meanwhile, several heat dissipation slots 501 are provided on the reinforcing rib 5. These heat dissipation slots 501 can increase the contact area between the reinforcing rib 5 and the air without significantly weakening the supporting strength of the reinforcing rib 5, thereby improving its heat dissipation capacity. The heat dissipation slots 501 gradually decrease in size from the side away from the cylinder 1 to the side closer to the cylinder 1. Since the reinforcing rib area closer to the cylinder 1 receives more heat, the smaller heat dissipation slots 501 can retain more metal structure in this area to ensure the supporting strength, while the area away from the cylinder 1 is enhanced by heat dissipation through larger heat dissipation slots 501, thereby achieving an optimized balance between structural strength and heat dissipation effect. In addition, the projected area of ​​the heat dissipation slots 501 on the reinforcing rib 5 is no more than 5% of the projected area of ​​the reinforcing rib 5. This design can strictly control the opening range of the heat dissipation slots 501, ensuring that the reinforcing rib 5 always has sufficient support capacity and avoiding a decrease in structural strength due to too many heat dissipation slots 501. Finally, the heat dissipation fins 4 and the cylinder 1 are integrally formed or welded together. The integrally formed structure eliminates the contact gap between the fins and the cylinder, reducing thermal resistance and allowing the heat from the cylinder 1 to be transferred to the heat dissipation fins 4 more quickly. The welded connection achieves a tight bond between the fins and the cylinder through metal fusion, which also ensures good heat conduction performance and avoids heat transfer obstruction due to loose connections or gaps. At the same time, the reinforcing ribs 5 are integrally formed with the adjacent heat dissipation fins 4. This structural design ensures that there is no contact thermal resistance between the reinforcing ribs 5 and the heat dissipation fins 4, allowing the heat from the heat dissipation fins 4 to be transferred directly and efficiently to the reinforcing ribs 5, further improving the heat conduction and diffusion efficiency of the entire heat dissipation structure. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
