Description

Technical Field

[0001] This utility model belongs to the field of diesel engine technology, and specifically relates to an engine body structure. Background Technology

[0002] The existing engine block structure has relatively small reinforcing ribs, which poses a risk of breakage during high-intensity operation. This solution optimizes the design of the reinforcing ribs.

[0003] Most existing engine blocks use built-in oil cooling structures, which are complex and have poor cooling effects. This solution optimizes the design of the oil cooling module, making the water flow more reasonable, improving the cooling effect, and simplifying the structure.

[0004] Therefore, in view of the shortcomings of the above-mentioned solution in actual production and implementation, it has been modified and improved. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after a lot of ingenuity and experimentation, this utility model was created, and an engine body structure is provided. Utility Model Content

[0005] This utility model proposes an engine body structure that solves the problems in the prior art.

[0006] The technical solution of this utility model is implemented as follows: an engine body structure, including an engine body, a transition piece, and an oil cooler, wherein the two ends of the transition piece are respectively connected to the engine body and the oil cooler, the engine body is provided with reinforcing ribs that cooperate with the transition piece, and the transition piece is provided with columns that cooperate with the oil cooler.

[0007] The above scheme adopts a compact series arrangement of the transition components and the mechanical cooler, which reduces pipe bends and pressure drops and shortens the heat transfer distance; while the optimized design of the reinforcing ribs and columns makes the overall strength greater.

[0008] As a preferred embodiment of the engine block structure, the transition component is provided with a cold water inlet, a hot water outlet, a hot oil inlet, a cold oil inlet hole, a main oil passage pipe, a hot oil inlet pipe, and a guide plate.

[0009] As a preferred embodiment of the engine body structure, the engine body includes an engine water inlet chamber and a water return chamber, with the cold water inlet corresponding to the engine water inlet chamber and the hot water outlet corresponding to the water return chamber.

[0010] In a preferred embodiment of the engine block structure, the hot oil inlet corresponds to the input end of the oil cooler, and the cold oil inlet corresponds to the output end of the oil cooler.

[0011] In a preferred embodiment of the engine block structure, the main oil passage pipe and the hot oil input pipe are not connected.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: The engine structure adopts a bypass form between the oil cooler water circuit and the engine block water circuit. The water in the engine block enters the engine cooler water circuit. At this time, the engine cooler water circuit and the engine block water circuit are connected in parallel, which not only meets the cooling requirements, but also reduces the water flow resistance, which is beneficial to the selection of water pump. At this time, due to the reduced resistance, the water flow speed of the engine cooler is increased, which improves the heat dissipation efficiency of the engine cooler and is more conducive to energy saving and emission reduction.

[0019] 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.

[0020] like Figure 1-4As shown, an engine block structure includes: an engine block 1, a transition piece 2, and an oil cooler 3. The two ends of the transition piece 2 are respectively connected to the engine block 1 and the oil cooler 3. The engine block 1 is provided with reinforcing ribs that cooperate with the transition piece 2, and the transition piece 2 is provided with columns that cooperate with the oil cooler 3.

[0021] The transition component 2 is equipped with a cold water inlet 21, a hot water outlet 22, a hot oil inlet 23, a cold oil inlet 24, a main oil passage pipe 25, a hot oil inlet pipe 26, and a guide plate 27.

[0022] The engine body 1 includes an engine water inlet chamber 11 and a water return chamber, a cold water inlet 21 corresponding to the engine water inlet chamber 11, and a hot water outlet 22 corresponding to the water return chamber.

[0023] Among them, the hot oil inlet 23 corresponds to the input end of the oil cooler 3, and the cold oil inlet 24 corresponds to the output end of the oil cooler 3.

[0024] The main oil passage pipe 25 and the hot oil input pipe 26 are not connected.

[0025] Furthermore, the engine block 1, as the core power unit, has a main oil passage inside, which is connected to the inlet of the oil cooler 3, for lubricating the various moving parts of the engine.

[0026] The transition piece 2 and the oil cooler 3 are arranged in a compact series to reduce pipe bends and pressure drop, and shorten the heat transfer distance; while the optimized design of the reinforcing ribs and columns makes the overall strength greater.

[0027] Furthermore, the transition piece 2 is used to connect the engine block 1 and the oil cooler 3. It is made of high-strength metal material and has both sealing and fluid guiding functions. The transition piece 2 has independent oil and water passages, which are precisely machined to ensure that they do not interfere with each other.

[0028] The oil cooler 3 adopts a plate or tube heat exchange structure, and integrates hot oil channels, cooling water channels and guide plates internally. Through counter-current heat exchange between hot oil and cooling water, the oil temperature is rapidly reduced.

[0029] During the cooling water circulation process:

[0030] The high-temperature cooling water output from the engine block 1 enters the cold water inlet 21 through the pipeline. After being distributed by the internal flow channel, part of the water flows into the oil cooler 3 for deep cooling, while the rest of the cooling water does not pass through the oil cooler 3 and is directly returned to the engine through the bypass guide plate 27 of the transition piece 2. The cooling water entering the oil cooler 3 exchanges heat with the hot oil inside, and after the temperature drops, it flows out through the outlet and finally flows back into the engine.

[0031] During the oil circulation process:

[0032] High-temperature engine oil flows from the main oil passage of the engine block 1 into the hot oil inlet pipe, and then enters the oil cooler 3 through the hot oil inlet 23. The cooled engine oil then flows out through the cold oil inlet 24 into the main oil passage pipe 25. The pipes between the cold oil inlet and the hot oil inlet are not connected inside the transition piece 2. This design ensures that the hot oil and cold oil do not mix, avoids cross-conduction of heat, and improves the cooling effect.
