Installation size

Before starting, check all accessories and instruments and ensure that all connections are tight Unscrew the screw plug located outside the oil outlet of the cooler, and slowly open the inlet valve Unscrew the exhaust valve in the cooler pipeline, and then slowly open the inlet valve. After the water is filled, close the inlet valve and exhaust valve, and the water and oil are in a static state. After heat exchange, the temperature difference gradually decreases. After the water temperature rises by 5-10 ℃, open the discharge valves of the cooling water and oil, and gradually open the inlet valves of the cooling water and oil to keep them in a flowing state. When the cooler malfunctions or stops working normally, the operating steps are to first close the inlet valves of the oil and cooling water, then close the discharge valves of the oil and cooling water, and then unscrew the drain plug on the drain oil interface to drain the accumulated cooling water and oil in the cooler.

Model Description: The GL tube type oil cooler heat exchange tube material adopts low ribbed finned copper tube, and adopts manufacturing processes such as transverse baffle plate, longitudinal turbulence plate structure, and mechanical expansion tube. Therefore, it has the advantages of novel structure, small volume, light weight, and heat exchange. 2LQFW type tubular cooler can be customized non-standard. Using low ribbed finned copper tubes, and employing manufacturing processes such as transverse baffle plates, longitudinal turbulent plate structures, and mechanical expansion tubes, it has the advantages of novel structure, small volume, light weight, and heat transfer. The tube type cooler adopts a dual structure, consisting of two oil coolers of the same area and a three-way valve device, one working and the other standby. Each tube type cooler can bear the cooling load of the entire system. One end of the tube plate is fixed, and the other end is a floating, detachable tube bundle and water chamber cover, which is easy to clean, inspect and maintain during operation. The material of the tubular cooler can be selected from various options based on the usage location and water system conditions.

The technical problem to be solved by this utility model is to provide a tube type oil cooler with better cooling effect. The technical solution of the present utility model is to provide a tubular oil cooler with the following structure: a left end cover, a right end cover, a housing provided with an oil inlet and an oil outlet, multiple baffle plates staggered and installed in the housing to allow hydraulic oil to flow in a tortuous manner, and a heat exchange component installed in the inner cavity of the housing through two fixed plates. The heat exchange component includes an inlet component and an outlet component, both of which are composed of several heat exchange tubes arranged along the axial direction of the housing. The two fixed plates are respectively connected to the left and right ends of the housing, and the left and right end covers are located on the left and right sides of the housing and connected to the fixed plate. The right end cover is provided with an inlet. The outlet is connected to the inlet component, and the inlet is connected to the inlet component. The outlet is connected to the outlet component, and a sleeve is tightly fitted on the outer wall of the heat exchange tube, A spiral heat exchanger is installed on the outer wall of the sleeve. The tubular oil cooler described in this utility model, wherein several axial heat dissipation fins can be uniformly distributed on the outer peripheral wall of the shell. The tubular oil cooler described in this utility model, wherein the shell can be made of aluminum alloy material. After adopting the above structure, compared with the existing technology, the tubular oil cooler of this utility model has the following advantages: the outer surface of the heat exchange tube is relatively smooth compared to the existing technology, resulting in a smaller heat exchange area between the heat exchange tube and the hydraulic oil. The spiral heat exchange fins set on the sleeve of the tubular oil cooler of this utility model greatly increase the heat exchange area between the heat exchange tube and the hydraulic oil, thereby improving the cooling effect of the tubular oil cooler of this utility model on the hydraulic oil in the hydraulic pipeline. The appearance and structure of the tubular cooling system are shown in Figure 2, consisting of multiple cooling water pipes, water side end cover plates and cylinders, as well as sealing gaskets and other components. The inside and outside of the cooling water pipe are sealed and separated. The cooling water flows from inside the pipe, while the hot oil flows from outside the pipe and undergoes heat exchange through the pipe wall to cool down the hot oil before flowing out from the outlet.

3. The standard for oil-water interface flanges shall comply with JB/T81-94, and non-standard flanges shall meet the piping requirements according to user requirements.
4. According to the AP Ⅰ 614 standard, the cooler adopts a dual structure, consisting of two equally sized coolers and a three-way valve device, one working and one standby. Each cooler can withstand the cooling load of the entire system. One end of the tube plate is fixed and the other end is floating. The detachable tube bundle and water chamber cover are convenient for cleaning, inspection, and maintenance during operation. The material of the cooler can be selected according to the usage location and water system conditions. The water chamber, shell, and three-way valve can be made of carbon steel or all stainless steel, and the tube plate can be made of carbon steel, stainless steel, or brass plate; The pipe materials can be selected from ordinary brass tube H68, arsenic brass tube HSn70-1A, aluminum brass tube HA177-2A, stainless steel tube 1Cr18Ni9Ti, B10, B30, etc.
