Abstract
Description
Technical Field
[0001] The utility model relates to a cylinder block, in particular to an engine cylinder block capable of dissipating heat from a lubrication system. Background Art
[0002] The cylinder block is an important component of the engine. It constitutes the framework of the engine, is the installation foundation of various mechanisms and systems of the engine, and bears various loads. During the operation of the engine, lubrication is required to reduce the friction between components.
[0003] Currently, engines on the market only cool the engine itself and do not have a separate cooling system for the internal lubrication system. However, the temperatures at positions such as the pistons through which the lubricating oil passes are relatively high. Since the lubricating oil is recycled, the temperature of the lubricating oil will rise rapidly after being used for a period of time. When the temperature of the lubricating oil is too high, the direct harm of over-temperature use is to accelerate oxidation and deterioration, and generate acidic substances, some insoluble substances and precipitates, such as sludge and varnish. The oxidation of the oil product will produce some insoluble substances and precipitates, such as sludge and varnish. In addition, the viscosity of the lubricating oil will decrease, resulting in a thinner lubricating oil film. If the oil film thickness is too thin, it is not sufficient to provide lubrication protection. Summary of the Utility Model
[0004] Based on the deficiency that the prior art does not provide a cooling structure for the lubrication system, resulting in an increase in the temperature of the lubricating oil and bringing a series of adverse effects, the utility model provides an engine cylinder block capable of dissipating heat from the lubrication system.

[0008] Preferably, the shape of the convex portion fits the shape of the bottom of the convex portion.
[0009] Preferably, the water cooling cavity extends to the convex portion so that the bottom part of the water cooling cavity extends into the lubrication cavity.

[0024] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.
[0025] It should be noted that similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.
[0026] Embodiment
[0027] This embodiment mainly elaborates on the title of the engine cylinder block that can dissipate heat from the lubrication system, specifically as follows:
[0028] Main solution :
[0029] The engine cylinder block that can dissipate heat from the lubrication system, as Figures 1 - 5 shown, includes a cylinder block body 10. A lubrication box body 20 is provided on the cylinder block body 10. The lubrication box body 20 has a lubrication cavity 200. An opening is provided on the side of the lubrication cavity 200. A cover 30 is detachably connected to the opening. The cover 30 is a double-layer structure with a water-cooling cavity inside. In this solution, the lubrication box body 20 is set as a split structure, and the cover 30 is set as a double-layer structure to set a water-cooling cavity in the cover 30, and the oil temperature is suppressed by injecting water, so as to avoid too high lubricating oil temperature.
[0030] Cover structure :
[0031] As Figure 5 shown, a convex portion 303 is provided on the inner side of the cover 30. The convex portion 303 extends into the bottom of the lubrication cavity 200. Preferably, the shape of the convex portion 303 matches the shape of the bottom of the convex portion 303. Preferably, the water-cooling cavity extends to the convex portion 303 so that the bottom part of the water-cooling cavity extends into the lubrication cavity 200. This solution increases the contact area and improves the effective area of heat exchange.
[0032] As Figure 4 shown, the cover 30 is provided with a water inlet 301 and a water outlet 302 that communicate with the water-cooling cavity. The water inlet 301 and the water outlet 302 are provided for adding coolant, and the adding time is before use or when the lubricating oil temperature is too high during use.
[0033] As Figure 4As shown in the figure, there are two water inlets 301 and one water outlet 302. The two water inlets 301 are located on the left side, and the water outlet 302 is located on the right side. Preferably, the heights of the two water inlets 301 are higher than the height of the water outlet 302. During use, the water inlets 301 and the water outlet 302 need to be blocked. This solution is arranged on both sides so that when temporarily replacing the coolant, the coolant can enter from one side and exit from the other side. At the same time, the height difference setting allows the coolant to enter from a higher place and exit from a lower place to replace the high-temperature coolant at the bottom.
[0034] Support structure :
[0035] As Figure 3 shown, at the bottom of the lubricating box body 20, there is an installation base 201, and in the middle of the installation base 201, there are several strip-shaped fins 202 for support and heat dissipation. The strip-shaped fins 202 are not only used to increase the support strength at this place, but also can dissipate heat from the lubricating box body 20.
[0036] Installation structure :
[0037] As Figure 2 shown, on the opening side of the lubricating box body 20 and the inner side of the cover 30, there are several groups of threaded posts that cooperate with each other, and in each group of threaded posts, there are screws for locking. During installation, a sealing ring can be arranged between the cover 30 and the lubricating box body 20 for sealing.
[0038] As Figure 2 and 5 shown, the lubricating box body 20 and the cover 30 have a gear shaft passing through, and the position where the gear shaft passes through is rotationally sealed through a sealing ring.
[0039] The above has introduced the title provided by the present utility model in detail. In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
