Atlas air compressor G series is a screw compressor, of which GR is a two-stage compression, oil injection screw compressor, and the supporting interstage cooler is a jacketed heat exchanger, which is widely used in air conditioning, refrigeration, chemical and other industrial fields. In order to save energy, slots are often opened on the surface of flat fins or corrugated plates are used to enhance heat transfer, mainly including flat fins, slotted fins, triangular corrugated fins, and sinusoidal corrugated fins. At present, the air coolers used in domestic industries such as refining, chemical, and power are developing towards * * and compactness. For many years, the air coolers used in these industries have mostly been wound or bimetallic rolled plates. Compared with traditional wound and rolled plates, the sleeve plate has a larger fluid flow resistance outside the tube, but its structure is compact, mechanical vibration is light, airflow is uniform, and heat transfer effect is greatly improved. Therefore, the sleeve plate has gradually eliminated traditional fin types and is increasingly used in gas-liquid heat exchange applications such as air coolers.

　　The inlet and outlet of the Cooper cooler water filter are designed as an upper and lower split, which not only prevents direct impact of water pressure on the filter screen, but also changes the situation of blockage caused by debris staying away from the discharge outlet during aggressive filter screen filtration. When discharging, several filter chambers need to be cleaned one by one, which often leads to blockage. The material and structure of the mesh board greatly improve the flow area of the water, effectively reducing the water resistance of the filter screen, ensuring reliable operation without jamming, blockage, or blockage, and greatly extending the filter screen. Using 2-8mm stainless steel plate for stamping and forming, the mesh core can withstand a differential pressure of 150kPa without deformation or damage. It has the characteristics of long working life, corrosion resistance, no rust, smooth appearance, and no scaling.　　Cooper coolers are very popular in future applications and daily life. Water enters the water filter through the lower inlet, and when impurities in the water pass through the mesh core, they are trapped on the mesh core due to their larger volume than the mesh core holes. When they accumulate to a certain amount, a certain pressure difference is formed at the inlet and outlet. The precision and diameter of the filter screen vary, and the pressure difference is also different. Scroll one step every 10-30 seconds, with the handle pointing towards each recess and fixed until it rotates once, closing the drain valve and completing manual drainage.

　　Stainless steel inner finned tubes are uniformly distributed with spiral electric heating alloy wires (nickel chromium, iron chromium alloys) along the axial direction of the inner base of the tube. The empty space is filled and compacted with magnesium oxide sand with good insulation and thermal conductivity. The ends of the tube mouth are sealed with silicone or ceramic. This metal armored electric heating element can heat air, Shanghai Xu Electronics waste heat recovery device metal mold, and various liquids. Stainless steel single head electric heating tube is made of metal tube as the outer shell. According to the different application states, safety and equipment requirements of the electric heating tube, the electric heating tube of the Hangzhou oxygen concentrator cooler will also include sealing structures, terminal structures, flanges, temperature control or safety wires and other structures.　　Stainless steel single head electric heating tube is made by placing an electric heating element in a metal tube, filling it tightly with crystalline magnesium oxide powder with good heat resistance, thermal conductivity, and insulation properties in the Qingjiang Petrochemical oil cooler, and processing it with other technologies. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple equipment, and long service life. Widely applicable to various equipment such as saltpeter tanks, water tanks, oil tanks, acid alkali tanks, melting furnaces for easily melted metals, air heating furnaces, drying furnaces, drying ovens, hot pressing molds, etc. Uniformly distribute spiral electric heating alloy wires along the axial direction of the base inside the pipe.
