Description

Technical Field

[0001] This utility model relates to a cooler, specifically a high-temperature resistant intercooler. Background Technology

[0002] As a major force in clean and renewable energy, wind power is undergoing a wave of development towards large-scale, high-volume operations, particularly in deep-sea and offshore applications. In this process, the demand for high-capacity, high-reliability, and high-efficiency supporting equipment is becoming increasingly prominent. To meet the demands of wind farms for higher exhaust pressure and larger flow rates, while also considering efficiency and equipment size and weight limitations, multi-stage compression technology has become an inevitable choice. However, multi-stage compression applications for wind power face unique and severe challenges: high-temperature environments, high-temperature exhaust, space and weight constraints, and high reliability and low maintenance requirements, which place extremely high demands on the cooling of multi-stage generators. If all generators share a single cooler, its cooling efficiency is difficult to meet; if each generator is equipped with its own cooler, it is not conducive to space and cost control. Summary of the Invention

[0003] This invention provides a high-temperature resistant intercooler with a simple structure that can meet the requirements of high air volume and rapid temperature reduction.

[0004] The technical solution adopted by this utility model is as follows: a high-temperature resistant intercooler, including a heat exchange box, an air inlet box with an air inlet connected to the left side of the heat exchange box, and an air outlet box with an air outlet connected to the right side of the heat exchange box. Multiple heat exchange tubes connected to the air inlet box are installed inside the heat exchange box. The key feature is that a water-cooled box is installed in the middle and / or rear section of the heat exchange box, the heat exchange tubes are connected to the water-cooled box, and the water-cooled box is connected to the air outlet box. Heat dissipation fins are installed outside the heat exchange tubes. A ventilation inlet is installed at the lower end of the heat exchange box corresponding to the position of the heat dissipation fins. A ventilation outlet box is connected to the rear part of the heat exchange box corresponding to the position of the heat dissipation fins, and a fan is installed inside the ventilation outlet box. A water-cooled tube is installed inside the water-cooled box, which is connected to the lower right side of the front part of the heat exchange box, passes through the interior, and exits from the upper left side of the front part of the heat exchange box.

[0005] The air inlet is located at the top of the air inlet box.

[0006] The air inlet is located at the rear.

[0007] The water-cooling pipe is made of copper.

[0008] The heat dissipation fins are made of aluminum.

[0009] The air inlet and air outlet are connected to grooved pipe joints.

[0010] The air inlet box, heat exchange box, air outlet box, and ventilation outlet box are made of Q235B steel plate.

[0011] An air inlet temperature sensor and an air inlet flow sensor are installed inside the air inlet box; an air outlet temperature sensor and an air outlet flow sensor are installed inside the air outlet box.

[0012] The beneficial effects of this utility model are as follows: The intercooler is installed between two adjacent generators. The high-temperature, high-flow exhaust gas from the preceding generator enters the air inlet box through the air inlet, and is then discharged from the air box through heat exchange pipes and a water-cooled box, ultimately supplying the next generator through the air outlet. When multiple generator sets are operating, an intercooler can be selected between every two generators, or a single intercooler can be installed after multiple generators are connected in series, based on the actual airflow and temperature of the generators. This reduces the number of coolers required for each generator set and effectively cools the air inside the generator set. Based on the monitoring data of the inlet and outlet air temperatures and flow rates between two adjacent generator sets, a fan with open-circuit cooling and / or water cooling can be selected in the subsequent intercooler. Air cooling is chosen for lower heat exchange requirements, water cooling for increased heat exchange requirements, and a combination of airflow and water cooling for higher heat exchange requirements. This ensures a stable supply of cooling air to the generators under large temperature differences, guaranteeing the long-term reliable operation of the multi-stage generator equipment.
