Description

Technical Field

[0001] This utility model relates to the field of oil cooler technology, specifically a multi-stage filtered oil cooling system. Background Technology

[0002] An oil cooler is a device used to cool engine oil. Engine oil is exposed to high temperatures while operating inside the engine, and it also absorbs and transfers heat from the engine. If the oil temperature is too high, it may deteriorate, reduce its lubricating performance, and even damage the engine. Therefore, the function of an oil cooler is to cool the oil and help maintain it within its suitable operating temperature range.

[0003] Oil coolers require the flow of coolant, and over time, scale will form in the coolant. Since existing coolers lack a filtration system, this scale remains inside, causing corrosion and affecting the cooler's performance. Therefore, those skilled in the art have developed a multi-filtration oil cooling system. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage filtration oil cooling system that prevents dirt from sticking to the filter screen after filtration, thereby improving filtration efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The oil cooler includes an oil cooler body, with an inlet and an outlet on one side. An inlet pipe is installed outside the inlet, and a filter pipe is threadedly connected to the end of the inlet pipe away from the inlet. A first filter screen is provided inside the filter pipe, and a threaded connecting pipe is fixed to the end of the filter pipe away from the inlet pipe. A second filter screen is provided inside the inlet pipe.

[0007] Furthermore, a mounting bracket is fixed to the inner wall of the liquid inlet pipe, the mounting bracket protrudes toward the filter pipe side, and the second filter screen is snapped into the side of the mounting bracket.

[0008] By adopting the above technical solution, the second filter screen is convex in shape, which prevents dirt that has not passed through the second filter screen from remaining on the second filter screen, thereby avoiding a reduction in the filtration efficiency of the second filter screen.

[0009] Furthermore, an annular fixing plate is fixed inside the filter tube, and a first filter screen is snapped onto the annular fixing plate. The first filter screen is conical and protrudes towards the side of the second filter screen.

[0010] Furthermore, by adopting the above technical solution, a flow guide block is fixed inside the filter tube. The flow guide block is wedge-shaped and tilted towards the outside of the filter tube. There is a gap between the top of the flow guide tube and the filter tube.

[0011] Furthermore, the filter tube has an opening on its side, and a retractable rubber sleeve is glued to the outside of the opening. The opening is located between the guide block and the first filter screen.

[0012] By adopting the above technical solution, water flows in along the surface of the guide block. Since the guide block is wedge-shaped and its upper surface is inclined, and the height between the top of the guide block (the highest point of the guide block) and the inner wall of the filter tube is less than that at the inlet of the filter tube, the water flows towards the first filter screen at the higher position after it flows in. The first filter screen is conical, so the water can wash the upper part of the first filter screen, washing away the dirt remaining on the first filter screen. The dirt automatically falls to the opening below and enters the retractable rubber sleeve for collection, so that the first filter screen has the ability to prevent dirt residue.

[0013] In summary, the beneficial technical effects of this utility model are as follows:

[0014] 1. An installation bracket is used, and the second filter screen is convex in shape to prevent dirt that has not passed through the second filter screen from remaining on the second filter screen, so as to avoid reducing the filtration efficiency of the second filter screen;

[0015] 2. A guide block is used. Water flows in along the surface of the guide block. Since the guide block is wedge-shaped and its upper surface is inclined, and the height between the top of the guide block (the highest point of the guide block) and the inner wall of the filter tube is less than that at the inlet of the filter tube, the water flows towards the first filter screen at the higher position after it flows in. The first filter screen is conical, so the water can wash the upper part of the first filter screen and wash away the dirt remaining on the first filter screen. The dirt automatically falls to the opening below and enters the retractable rubber sleeve for collection, so that the first filter screen has the ability to prevent dirt residue.

[0016] 3. A first filter and a second filter are adopted. The filtration efficiency is improved by the double-layer filter. The first filter is conical and the second filter is convex. Combined with the flow guide block on the side of the first filter, both filters have the ability to prevent dirt residue. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution comprising an oil cooler body 1, with an inlet 2 and an outlet 3 on one side. The inlet 2 is characterized by an inlet pipe 4 externally mounted thereon, a filter pipe 5 threadedly connected to the end of the inlet pipe 4 away from the inlet 2, a first filter screen 6 inside the filter pipe 5, a threaded connecting pipe 7 fixed to the end of the filter pipe 5 away from the inlet pipe 4, and a second filter screen 8 inside the inlet pipe 4. In this embodiment, the pore size of the first filter screen 6 is larger than that of the second filter screen 8, forming multiple filtrations. Water enters the inlet pipe 4 along the filter pipe 5, passes through the first filter screen 6, and larger pieces of dirt remain on the outside of the first filter screen 6. After passing through the second filter screen 8 again, smaller pieces of dirt remain on the outside of the second filter screen 8.

[0025] A mounting bracket 9 is fixed to the inner wall of the liquid inlet pipe 4. The mounting bracket 9 protrudes towards the filter pipe 5 and the second filter screen 8 is snapped into the side of the mounting bracket 9.

[0026] The second filter screen 8 is convex to prevent dirt that has not passed through it from remaining on it, thus avoiding a reduction in its filtration efficiency. An annular fixing plate 10 is fixed inside the filter tube 5, and a first filter screen 6 is snapped onto the annular fixing plate. The first filter screen 6 is conical and protrudes towards the second filter screen 8.

[0027] A flow guide block 11 is fixed inside the filter tube 5. The flow guide block 11 is wedge-shaped and tilted towards the outside of the filter tube 5. There is a gap between the top of the flow guide block and the filter tube 5. An opening 12 is provided on the side of the filter tube 5. A retractable rubber sleeve 13 is glued to the outside of the opening 12. The opening 12 is located between the flow guide block 11 and the first filter screen 6.

[0028] When water enters, it flows along the surface of the guide block 11. Since the guide block 11 is wedge-shaped and its upper surface is inclined, and the height between the top of the guide block 11 (the highest point of the guide block 11) and the inner wall of the filter tube 5 is less than that at the inlet of the filter tube 5, the water flows towards the first filter screen 6 at the higher position. The first filter screen 6 is conical, so the water can wash the upper part of the first filter screen 6, washing away the dirt remaining on the first filter screen 6. The dirt automatically falls to the opening 12 below and enters the retractable rubber sleeve 13 for collection. The working principle of this utility model is as follows: A filter tube 5 is threadedly installed at the liquid inlet pipe 4 of the cooler to increase the filtration effect at the liquid inlet pipe 4. At the same time, a second filter screen 8 is installed on the side of the liquid inlet pipe 4 near the filter tube 5. The filtration efficiency is improved by the double-layer filter screen. The first filter screen 6 is conical and the second filter screen 8 is convex. Combined with the guide block 11 on the side of the first filter screen 6, both filters have the ability to avoid dirt residue, thus maintaining the filtration efficiency for a long time. In actual use, the filter tube 5 is installed on the liquid inlet pipe 4, and the other side of the filter tube 5 is connected to a water pipe through a threaded connection pipe 7.

[0029] When cleaning the filter tube 5, after disassembly, rinse it with water in the reverse direction, and at the same time fold the retractable rubber sleeve 13 toward the inside of the filter tube 5 to flush out the dirt inside the filter tube 5.
