[0001] The present application relates to the field of cooling equipment, and in particular to a guide cooler. Background Art

[0002] Coolers are widely used in the industrial field to cool various fluids. In the prior art, the oil to be cooled is usually placed in an oil tank, coolant is passed through a cooling pipe, and then the cooling pipe is placed in the oil tank to cool the hot oil. However, with the continuous development of industrial technology, the requirements for cooling efficiency and cooling capacity are also constantly increasing.

[0003] Although the traditional oil cooling method can meet certain cooling needs, it has problems such as low cooling efficiency and limited cooling capacity. This is because the traditional cooling method is mainly achieved through heat exchange between the cooling pipe and the oil, and the contact area and heat exchange efficiency between the cooling pipe and the oil become the main factors limiting the cooling capacity.

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] An embodiment of the present application discloses a guide cooler.

[0034] Reference Figure 1 and Figure 2 A guide cooler includes an upper shell 1, a lower shell 2 and a plurality of cooling pipes 3. The upper shell 1 and the lower shell 2 are detachably connected and can be connected by fasteners such as bolts, which is convenient for installation and maintenance. The upper shell 1 is connected with an oil inlet pipe 11 and an oil outlet pipe 12. The oil inlet pipe 11 and the oil outlet pipe 12 are both connected to a tank cover 16 by a flange. The flange connection has good sealing and detachability, which is convenient for the connection and maintenance of the pipeline.

[0035] Reference Figure 2 and Figure 3, coolant is added to the lower shell 2, and the cooling pipe 3 is immersed in the coolant. A partition plate 4 is provided in the upper shell 1, which divides the interior of the upper shell 1 into several chambers. The chamber connected to the oil inlet pipe 11 is different from the chamber connected to the oil outlet pipe 12, ensuring that the hot oil can fully flow and be cooled in the cooling pipe 3. The cooling pipe 3 is arranged between the oil inlet pipe 11 and the oil outlet pipe 12 in the horizontal direction, and the adjacent chambers are connected through the cooling pipe 3, thereby forming a continuous oil passage. The hot oil enters a chamber of the upper shell 1 from the oil inlet pipe 11, then flows through the cooling pipe 3, is cooled by the coolant in the cooling pipe 3, and then enters the adjacent chamber and continues to flow until it flows out from the oil outlet pipe 12. In this way, the hot oil can fully flow in the cooling pipe 3 and exchange heat with the coolant, thereby achieving effective cooling.

[0036] Reference Figure 1 and Figure 3 The upper shell 1 is also connected to a refueling pipe 13 and an oil drain pipe 14. The chambers connected by the refueling pipe 13, the oil drain pipe 14, the oil inlet pipe 11 and the oil outlet pipe 12 are all different. This design allows for flexible refueling or oil draining operations as needed during the cooling process without affecting normal cooling work. After long-term use of the cooling oil, part of the cooling oil is taken away by the equipment or parts that need to be cooled, resulting in a drop in the cooling oil level. The cooling oil needs to be replenished. At this time, the control valve 5 of the refueling pipe 13 can be opened to add new oil to the corresponding chamber, and then flow to the entire cooling system through the cooling pipe 3. Similarly, after long-term use of the cooling oil, the cooling oil is contaminated by the equipment or parts that need to be cooled, resulting in more impurities in the cooling oil, and the cooling oil needs to be replaced. At this time, the control valve 5 of the oil drain pipe 14 can be opened, the control valve 5 of the oil outlet pipe 12 and the refueling pipe 13 can be closed, the old oil can be discharged from the corresponding chamber, and then the control valve 5 of the oil outlet pipe 12 and the refueling pipe 13 can be opened, and the control valve 5 of the oil drain pipe 14 can be closed to add new cooling oil. This design not only improves the convenience of use, but also ensures the continuous and stable operation of the cooling system. In addition, during operation, the control valves 5 of the oil filling pipe 13, the oil drain pipe 14, the oil inlet pipe 11 and the oil outlet pipe 12 are all opened, and cold oil is added from the oil filling pipe 13 to speed up the cooling of the hot oil.

[0037] Reference Figure 1 and Figure 4The upper shell 1 includes a tube bearing plate 15 and a box cover 16, and the cooling pipe 3 is inserted on the tube bearing plate 15 and communicated with the box cover 16. The tube bearing plate 15 and the box cover 16 are detachably connected, which is convenient for installing, repairing and replacing the cooling pipe 3. The box cover 16 can be easily opened to expose the cooling pipe 3. In this way, when the cooling pipe 3 needs to be inspected or replaced, there is no need to disassemble the entire upper shell 1, and the operation can be carried out by opening the box cover 16, which greatly simplifies the maintenance process. A sealing gasket 153 is provided between the tube bearing plate 15 and the box cover 16, and then the tube bearing plate 15 and the box cover 16 are fastened by fasteners such as bolts, and the sealing gasket 153 is squeezed therein, thereby improving the sealing performance of the cooler.

[0038] Reference Figure 1 and Figure 5 In order to improve the stability of the cooling pipe 3, a plurality of threaded rods 151 are provided on the tube bearing plate 15, and a stabilizing plate 31 is sleeved on the outer wall of the cooling pipe 3. One end of the threaded rod 151 away from the tube bearing plate 15 passes through the stabilizing plate 31 and is threadedly connected with a nut 152 for limiting. By tightening the nut 152, the stabilizing plate 31 can be firmly fixed on the threaded rod 151, thereby stabilizing the cooling pipe 3.

[0039] Reference Figure 2 and Figure 4 , the cooling tube 3 adopts a U-shaped tube design. The top two ends of the U-shaped tube are connected to the tube plate 15. This design can increase the contact area between the cooling tube 3 and the hot oil, thereby improving the cooling effect. At the same time, the design of the U-shaped tube can also cause the cooling medium to form turbulence in the tube, further enhancing the heat exchange effect. After the hot oil enters a chamber of the upper shell 1 from the oil inlet pipe 11, it flows through the U-shaped cooling tube 3. In the curved part of the U-shaped tube, the flow velocity of the hot oil will increase, and the contact with the cooling medium will be more sufficient. In this way, the heat in the hot oil can be transferred to the cooling medium more quickly, thereby achieving more efficient cooling. The cooled oil flows out from the oil outlet pipe 12, completing the entire cooling cycle.

[0040] The implementation principle of a guide cooler in an embodiment of the present application is as follows: a partition plate 4 is used to divide the interior of the upper shell 1 into multiple chambers, and the adjacent chambers are connected through the cooling pipe 3, so that the hot oil flows into the upper shell 1 from the oil inlet pipe 11, flows through each chamber in turn along the cooling pipe 3, and finally flows out from the oil outlet pipe 12, thereby increasing the cooling time of the hot oil. At the same time, the coolant cools the cooling pipe 3 in the lower shell 2. This structure significantly improves the cooling efficiency.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
