Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment control technology, and relates to an ice machine compressor starter cabinet, which is particularly suitable for starter control equipment that achieves efficient air exchange by optimizing the heat dissipation structure. Background Technology

[0002] The compressor starter cabinet for ice machines is a crucial electrical device in refrigeration systems used to control the start-up and operation of the compressor. Its main function is to reduce the current surge during compressor startup through soft-start technology, minimizing damage to the power grid and mechanical components, while protecting electrical elements to ensure long-term stable operation. With the widespread application of refrigeration equipment in industrial, commercial, and residential sectors, the demand for compressor starter cabinets for ice machines is increasing, especially in industries such as cold chain logistics, food processing, and pharmaceutical storage, where the requirements for performance and reliability are constantly rising. However, existing compressor starter cabinets for ice machines still have some shortcomings in design and application, limiting their performance in specific environments.

[0003] In traditional refrigerator compressor starter cabinets, heat dissipation is a key factor affecting equipment performance. Because the compressor generates a significant amount of heat during startup and operation, the electrical components inside the cabinet (such as thyristors, contactors, and control circuit boards) need to operate within a suitable temperature range to avoid performance degradation or component damage due to overheating. Conventional heat dissipation methods typically rely on simple ventilation holes or built-in fans to remove heat through natural convection or forced airflow in one direction. However, this design has significant limitations in refrigeration environments. First, refrigerators typically operate in low-temperature, high-humidity conditions. External cold air may carry moisture or fine particles into the cabinet through the ventilation holes, causing electrical components to become damp or accumulate dust, potentially leading to short circuits or corrosion. Second, traditional ventilation designs have a single airflow path, resulting in uneven heat distribution. Areas inside the cabinet near the core electrical components often struggle to cool quickly, affecting heat dissipation efficiency. Furthermore, exposed ventilation holes are susceptible to intrusion by external objects (such as insects and dust), increasing maintenance difficulty.

[0004] To address heat dissipation issues, some existing technologies attempt to introduce more complex cooling systems into the start-up cabinet. For example, some designs enhance airflow by adding multiple fans or external cooling pipes, but this often results in a complex cabinet structure, occupying additional space and hindering the compact installation requirements of refrigeration equipment. Other designs supplement cooling by adding heat sinks or water-cooling devices to the outside of the cabinet, but water-cooling systems may cause condensation or freezing in low-temperature environments and are costly, making widespread adoption difficult. Still other technologies incorporate simple exhaust pipes within the cabinet, but these pipes are typically designed with a fixed cross-section, lacking optimized airflow velocity and pressure distribution, failing to effectively create a stable ventilation cycle, and thus offering limited heat dissipation.

[0005] Furthermore, the layout of the heat dissipation units and electrical components in existing starter cabinets lacks coordination. For example, heat sinks are often directly mounted on electrical components (such as thyristors), but their position is weakly correlated with the ventilation path, making it difficult to fully utilize the cooling capacity of external cold air. The design of the air inlet and outlet positions also often ignores the characteristics of the cooling environment, such as failing to consider moisture isolation or air filtration, making it difficult to maintain a clean and dry environment inside the cabinet. These problems not only reduce heat dissipation efficiency but may also affect the lifespan of electrical components and the overall stability of the system.

[0006] To address the aforementioned issues, the market urgently needs a refrigerator compressor starter cabinet that is simple in structure, highly efficient in heat dissipation, and adaptable to refrigeration environments. An ideal design should maintain a compact structure while optimizing airflow paths to improve ventilation efficiency, and reducing the impact of moisture and dust through a reasonable intake and exhaust layout and protective measures. Furthermore, the heat dissipation unit should work closely with electrical components (such as radiators) to ensure that heat in the core area is quickly dissipated, while reducing maintenance costs and installation difficulty.

[0007] While some improvements have been attempted in existing technologies, the aforementioned problems have not been completely resolved. For example, some patents propose optimizing ventilation through perforated plates or grilles, but these fail to effectively control airflow direction, resulting in limited improvements in heat dissipation efficiency. Other designs add sensors to monitor temperature, but do not structurally optimize the heat dissipation channels, making fundamental improvements difficult. Therefore, developing a starter cabinet for ice machine compressors that balances efficient heat dissipation, environmental adaptability, and structural simplicity has become a pressing technical challenge in this field. This invention aims to provide a starter cabinet that achieves efficient air exchange, adapts to refrigeration environments, and is easy to install through an innovative heat dissipation unit design, thereby addressing the heat dissipation bottlenecks and insufficient protection issues in existing technologies. Utility Model Content

[0008] In view of this, the purpose of this utility model is to solve the above problems and provide a starter cabinet for an ice machine compressor.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A starter cabinet for an ice machine compressor includes a cabinet body and a starter unit disposed within the cabinet body. A heat dissipation unit is provided on one side of the cabinet body. The heat dissipation unit includes a fan, an exhaust pipe, and an intake pipe. The intake pipe is fixed to the cabinet body and is fixedly fitted onto one end of the exhaust pipe. The fan is disposed at the other end of the exhaust pipe and located inside the exhaust pipe. An exhaust channel is formed inside the exhaust pipe, and an intake channel is formed between the exhaust pipe and the intake pipe.

[0011] The exhaust channel has a gradually changing cross-section structure. The cross-section of the exhaust channel gradually decreases from the fan side to the inside of the cabinet, and then gradually increases from the inside of the cabinet to the outside of the cabinet. The fan drives the air inside the cabinet to be quickly discharged along the exhaust channel, forming a low-pressure zone inside the cabinet. The cold air outside the cabinet enters the cabinet through the air intake channel because the pressure is greater than that inside the cabinet, thus achieving ventilation and heat dissipation.

[0012] Furthermore, a support frame is provided between the intake pipe and the exhaust pipe, and the intake pipe and the exhaust pipe are fixedly connected by the support frame.

[0013] Furthermore, the air intake pipe is located near the top of the cabinet, the exhaust pipe extends in a curved shape to the side opposite to the air intake pipe, and the inlet of the air intake pipe is located in the middle of the cabinet.

[0014] Furthermore, the starting unit is equipped with a radiator, and the inlet of the air intake pipe is located close to the radiator.

[0015] Furthermore, the top of the cabinet is provided with a cover that extends outward from the top of the cabinet, and the air intake pipe is located inside the cover.

[0016] Furthermore, a filter screen is provided at the end of the air intake pipe.

[0017] Furthermore, a temperature sensor is also installed inside the cabinet, and the temperature sensor is linked to the fan.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model combines a gradual exhaust channel, a packaged pipe system, and a protective structure to form a compact and efficient heat dissipation system. Compared with existing technologies, the cabinet structure is simpler, the air exchange path is better, and the protection performance is stronger, making it particularly suitable for ice machine compressor start-up cabinets operating in low-temperature and high-humidity refrigeration environments.

[0020] 2. The heat dissipation unit adopts a packaged intake and exhaust pipe structure. The exhaust pipe features a gradually decreasing cross-section exhaust channel, with the cross-section gradually decreasing from the fan side to the inside of the cabinet, and then gradually increasing from the inside to the outside. This channel design optimizes the airflow path, allowing hot air inside the cabinet to be smoothly exhausted, while cool air from outside enters the cabinet through the intake channel, forming a stable air circulation. Compared to traditional fixed-section ventilation ducts, the gradually decreasing channel structure achieves a more efficient ventilation effect within the limited space of the cabinet.

[0021] 3. The air intake pipe is fixed to the top of the cabinet, with the inlet located in the middle near the radiator, and the exhaust pipe extends in a curved shape to the opposite side. This layout prioritizes the flow of incoming cold air to the radiator of the starting unit, enhancing the cooling effect of the core electrical components. The support frames for the air intake and exhaust pipes are fixedly connected, ensuring the stability of the pipe structure and reducing the risk of vibration or loosening during long-term operation.

[0022] 4. The top cover of the cabinet and the filter at the end of the air intake pipe provide additional protection for the heat dissipation unit. The cover extends outward from the top, covering the air intake pipe inlet to prevent rainwater or external debris from directly entering the channel. The filter is secured to the inside of the air intake pipe with clips, blocking dust and fine particles, keeping the air inside the cabinet clean, and reducing the risk of electrical component failure due to dust accumulation. These two designs are particularly suitable for the low-temperature, high-humidity environment in which ice machines operate, helping to extend the equipment's lifespan.

[0023] 5. The connection design between the temperature sensor and the fan enables the heat dissipation unit to work in coordination with temperature changes within the cabinet. The sensor is fixed inside the cabinet and connected to the fan via wires, providing structural support for the operation of the heat dissipation unit and optimizing the working synergy between the heat dissipation unit and electrical components.
