It is an ideal cooling device.

Working principle of tubular cooler

Manual working process: After the water filter is connected to the pipeline system, water enters the filter through the lower inlet. 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, it causes a certain pressure difference between the inlet and outlet. (The precision and diameter of the filter screen vary, and the pressure difference is generally 0.15Mpa.) Manually open the drain valve to start draining. Rotate the handle clockwise or counterclockwise every 10-30 seconds. Rotate one step and fix the handle to each concave part. The water flow will reverse wash the impurities and dirt attached to the inner wall of the mesh core. Rotate once, close the drain valve, and manually drain the water.

1. Differential pressure discharge: When impurities accumulate to a certain amount, the differential pressure signal between the cooling water inlet and outlet pipes is used to backwash the discharge. That is, the electric contact pressure gauge is connected to the control signal, and the control mechanism opens the electric discharge valve. The electric reducer will operate at a speed of 3-6 revolutions per minute, and the water flow will reverse wash the impurities and pollutants attached to the inner wall of the mesh core. They will be discharged into the cooling water outlet pipe through the discharge pipeline and discharge valve, and the cleaning time is about 5-10 minutes. When large debris appears and the filter cannot operate properly, the electric device should run in the opposite direction to flush the debris.

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.

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.
