During the manufacturing process of die-cast radiators, you may encounter some common problems, here are some of them: 1. Stomata and bubbles: Problem description: Porosity and bubbles are common defects in the die-casting process and may appear on the surface or inside the radiator. Solution: Optimize the die-casting process to ensure smooth metal flow and avoid gas being trapped in the casting. The generation of pores and bubbles can be reduced by improving mold design, controlling pouring temperature and speed, and adopting a suitable pouring system. 2. Thermal cracks: Problem description: During the cooling process of the radiator, thermal cracks may occur due to uneven metal temperature or rapid cooling. Solution: Optimize the casting process, control the cooling rate and temperature uniformity of the metal, and avoid excessive cooling or the occurrence of stress concentration areas. In addition, appropriate alloy composition and process parameters are selected to reduce the occurrence of hot cracks. 3. Deformation and dimensional deviation: Problem description: The radiator may shrink and deform unevenly during the cooling process, resulting in size deviation or irregular shape. Solution: Optimize the mold design, take into account the shrinkage of the radiator, and use a suitable cooling system to ensure that the casting is cooled evenly and avoid deformation. In addition, post-processing processes, such as heat treatment or machining, can be used to correct dimensional deviations in castings. 4. Surface quality issues: Problem Description: The surface of the radiator may be oxidized, blemished or rough. Solution: Strengthen mold surface treatment, such as polishing, sandblasting, etc., to improve surface quality. In addition, the coating materials should be selected and used rationally to control the oxidation reaction during the casting process to reduce the occurrence of surface defects. By optimizing the process, improving equipment and strengthening quality management, these problems can be effectively solved and the quality and production efficiency of die-cast radiators can be improved.

There are some differences in the principle of refrigeration and working methods of air-cooled screw-type cold water machines and air-cooled cold water machines. It is mainly reflected in the type of compressor and refrigeration method: 1. Compressor type: Wind-cold screw-type cold water machine: Use screw compressor as the core component of the refrigeration system. The screw -type compressor compress the refrigerant through the rotation of the screw, which has efficient and stable refrigeration performance and is suitable for a large refrigeration system. Cold-cold cold water machine: Usually a reciprocating compressor or screw compressor. Compared with the screw -type cold water machine, the type of compressor of the air-cooled cold water machine may be more diverse, but in some cases, the reciprocating compressor may be lower than the screw compressor, but the efficiency is usually lower. 2. Refrigeration method: Wind-cold screw-type cold water machine: Use a fan to flow the air over the condenser, so as to cool the refrigerant and distribute the heat into the environment. This method can save water resources and suitable for the scene of water -free cooling system. Cold-cold cold water machine: It also uses a fan to flow the air over the condenser, but its compressor type may not be limited to screw type, which can be duplex. This method can also distribute heat into the environment, but in some cases, more water resources may be needed to maintain the cooling effect. In summary, the air -cooled screw -type cold water machine has some differences in the type and cooling method of the compressor and the cooling method. Screw -type cold water machines usually have higher energy efficiency and stability, suitable for the requirements of large refrigeration systems, while air-cooled cold water machines may have some advantages in the cooling method and cost, suitable for the needs of small and medium-sized refrigeration systems.

Spot coolers and mold temperature controllers are two common devices used to control mold temperature. They have some differences in working principles and application scenarios: 1. Cooling machine: Working principle: The spot cooler controls the temperature of the mold by directly injecting refrigerant into the cooling channel in the mold. The refrigeration process is usually accomplished using components such as compressors, condensers, evaporators, and control systems. Application scenario: The spot cooler is suitable for scenarios where precise control of mold temperature is required, especially for large and complex molds and production processes that require high product quality. Spot coolers generally provide greater temperature control accuracy and stability. 2. Mold temperature controller: Working principle: The mold temperature controller circulates the heat transfer medium (usually water or oil) through the cooling channels of the mold to absorb or release heat to control the temperature of the mold. The mold temperature controller includes heating elements, circulation pumps, control systems and other components. Application scenario: Mold temperature controller is suitable for situations where the mold temperature requirements are not too strict, such as in plastic injection molding, die-casting and other production processes. Mold temperature controllers generally provide relatively low cost and simpler operation, but the temperature control accuracy may not be as high as that of spot coolers. In general, spot coolers are suitable for production scenarios with higher mold temperature control requirements, while mold temperature controllers are more suitable for general mold temperature control needs. The choice of which equipment to use should be determined based on specific production needs, mold design and product quality requirements.
