Cooling Division Introduction

Wuxi cooling Jinxin Group Division located in the scenic Taihu Lake, Lake Economic Development Zone in Wuxi City. Ministry of Railways, Petrochemical Department, Ministry of Metallurgy, the Ministry of Shipping Corporation and other related manufacturing enterprises; and exempt enterprises in business, the title of brand-name enterprises in Wuxi City. Wuxi City was named for five consecutive years of civilization enterprises.
Large number of enterprises in recent years, the introduction of a variety of professionals, establish and improve the research and development center, to science and technology development and production of various types of motorcycle-specific radiator and cooling devices, widely used in railway industry.
In 2008 the company and the United States WABTEC-YOUNG TOUCHSTONE companies to develop mechanical connection Radiator Expansion for HXN5 China Mainline locomotive, 2009, 300 suppliers have been successful.
In 2009 the company with the German Hauck (HAUGG) joint venture, cooperation, development, manufacture cooling systems for locomotives harmony.
Division based on the comprehensive advantages of the Group and abroad, the Ministry of Railways leaps and bounds for high-speed motor car, motorcycle international introduction, the production of radiators and cooling systems. Radiator based company specializing in the production advantages, the Ministry of Railways have been classified as high-speed moving vehicles, electric locomotives, diesel locomotives and other radiator and cooling system sentinel providers. Division has developed a HXN5 motorcycle radiator, HXD3 locomotive compound cooler, DJ4 oil cooler, HXD2B electric locomotives (six-axle vehicles) oil cooler, CRH3-380A cooling system, CRH3-380 cooling system and a series of products .
The main production equipment: VAB-200 vacuum brazing furnace, VAB -460 vacuum brazing furnace, ultrasonic cleaning machine, JC23-25 open type tilting press, fin forming machine, drying equipment, 315T, 100T, 80T hydraulic press and 1 units, laser cutting machine, CNC shearing, CNC bending machines, machining centers, welding machine and the corresponding test equipment.
Design and Development Division, strong technical force, advanced facilities, with strict quality assurance system, a sound quality management program, has passed the ISO9001: 2000 quality system certification, the International Railway Industry Standard IRIS certification, ISO14001: 2004 Environmental Management System, GB / T28001: 2001 Occupational Health and Safety Management System Audit, EN 15085 welding management system audit, the company's production process in strict accordance with the implementation of standards and internal documents.
Main Products
A, FL220 composite cooler
FL220 composite cooler is mainly used for electric locomotives and converter transformer cooling system, transformer oil must cool down, while the converter cooling water (add a 55% ethylene glycol antifreeze) also need to be cooled, FL220-type complex configuration of the oil cooler, water radiator of a group, water, oil radiator cores are made of aluminum alloy plate-fin structure, water radiator, oil cooler radiator assembly composed of one. Composite cooler heat load Q ≥ 220KW, including water radiator heat emission Q ≥ 100KW, oil radiator heat emission Q ≥ 120KW, fully meet the requirements of the electric locomotives.
Second, CRH3 transformer cooling system
The cooling device for cooling the domestic high-speed EMU transformers, heat dissipation Q ≥ 300Kw. Because of the role of transformer oil pumps, transformers, heat the oil tank is sucked cooler, flow through the oil cooler, the heat to the oil cooling channel, and then by oil cooling channel on the air giving off heat, the use of the cooling fan through the air filter along the vertical vehicles to the direction of cooling air inhaled from the outside, so that air flow through cooling channel, absorbing heat, cooling air through the radiator to form the hot air blowing down towards the track bed, so as to achieve the purpose of the transformer oil cooling, keep the transformer allowed temperatures.
The cooling device using plate-fin heat exchanger, which is characterized by: (1) heat transfer efficiency, the fin boundary layer of fluid to continue to break the disturbance, which has a large heat transfer coefficient, while the partition wings the thickness of thin films with high thermal conductivity, so make plate-fin heat exchanger can achieve high efficiency; (2) compact, due to plate-fin heat exchanger with expansion of the secondary surface, making it the specific surface area up to 1000 ─ 2500M2/M3; (3) Lightweight, compact and more by the aluminum alloy; (4) adaptability, plate-fin heat exchanger suitable for: gas --- gas, liquid gas --- liquid --- liquid, heat transfer between the various fluids and the set of state change occurs the phase change heat transfer.
Third, the mechanical connection of copper radiator
Mechanical connection of massive copper heat sink is the company in order to meet China Mainline Locomotive (HXN5) requires the development of new products. The product cores with large integrated structure for the inner loop three-flow radiator, diesel engines can meet the cooling water jacket, oil cooler cooling and cooling in the cooling water requirements. Has the following characteristics:
1. More traditional style of small single radiator, space utilization is high;
2. The use of advanced flat tube expanding circle ("FLAT-ROUND") Expanding Technology, the overall strength, high stiffness, high vibration pressure;
3. Low wind resistance, high thermal efficiency;
4. Unique compensation structure, enhanced ability to compensate thermal expansion and contraction;
5. Has a strong disassembly and maintenance, maintainability and durability.
