It is to be understood that the words or words used in the present specification and claims are not to be construed in a conventional or dictionary sense and that the inventor can properly define the concept of a term in order to describe its invention in the best way And should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a flow separation type insert structure according to the present invention, and FIG. 2 is a mounting state view of a flow separation type insert structure according to the present invention. 1 and 2, a flow separating insert according to the present invention is inserted into a water jacket W of a cylinder block and includes a guide portion 100, a sealing portion 200, and a support portion 300 do.

The guide portion 100 is formed to be parallel to the horizontal end surface of the water jacket W and is disposed inside the water jacket W. The guide part 100 serves to guide a direction in which the sealing part 200 of a foamable material is foamed.

The guide part 100 is formed with a plurality of through holes 110 passing through the guide part 100 in the vertical direction. When the floating separable insert structure is mounted inside the water jacket (W) of the cylinder block, the water jacket (W) of the cylinder block is separated into the upper part and the lower part. At this time, when air flows into the lower portion of the water jacket W, the cooling water is not supplied as much as the volume occupied by the air, so that the cooling efficiency is lowered. Accordingly, a plurality of through holes 110 are formed so that the air introduced into the lower portion of the water jacket W can be discharged to the upper portion of the water jacket W. The air introduced into the upper portion of the water jacket W may be discharged to the outside of the water jacket W through another through hole (not shown).

The sealing part 200 is mounted on both sides of the guide part 100 and is expanded toward a side of the water jacket W to divide the water jacket W into an upper part and a lower part. The material of the sealing part 200 may be EPDM (ethylene propylene diene monomer) having anti-freeze and foaming properties.

That is, the sealing part 200 seals the side surfaces of the guide part 100 and the water jacket W so as to divide the water jacket W into an upper part and a lower part. At this time, in order to improve the mountability of the fluid-removable insert structure, the sealing part 200 is foam-molded and then pressed.

Further, the sealing part 200 expands when the temperature is higher than a predetermined temperature. Accordingly, it is possible to prevent a space between the insert structure and the cylinder block, which has occurred conventionally, and to improve the fuel economy of the vehicle by separating the cooling water flow between the upper portion and the lower portion of the water jacket W of the cylinder block.

In addition, anti-freezing liquid may be added to the cooling water of the vehicle, so that the sealing part 200 is preferably made of a material having anti-antifreeze property so as to prevent the sealing part 200 from being damaged.

The support part 300 supports the guide part 100 up and down to fix the position of the guide part 100 in the water jacket W. [ At this time, the support part 300 is disposed inside the water jacket W located outside the connection points of the plurality of cylinder bores.

FIG. 3 is a plan view of a flow separating insert according to a first embodiment of the present invention, FIG. 4 is an A side view of a flow separating insert according to a first embodiment of the present invention, and FIG.

The cooling water supplied from the water pump (not shown) is separated into the upper and lower portions of the water jacket W of the cylinder block to form a flow between the cut surfaces 400 and 400 '.

At this time, the guide part 100 and the sealing part 200 are bent downward from the support part 300 closest to the cut surfaces 400 and 400 'toward the cut surfaces 400 and 400'. This is to minimize the flow resistance since the guide portion 100 and the sealing portion 200 can act as a flow resistance of the cooling water flowing into the upper portion of the water jacket W of the cylinder block. As a result, the cooling water flow at the upper portion of the water jacket W of the cylinder block is strengthened, thereby improving the performance of the engine. At the same time, the flow of the cooling water flowing into the lower portion of the water jacket W of the cylinder block is induced, thereby contributing to reduction of friction loss and improvement of fuel consumption.

The guide part 100 and the sealing part 200 are formed on one side of the inside of the water jacket surrounding the cooling water inlet side cylinder bore # 1 and on the side of the cooling water inlet side cylinder bore # Set Angle (

Figure 112016021823760-pat00003
). That is, both the guide part 100 and the both cut surfaces 400 and 400 'of the sealing part 200 are bent to face the cooling water inlet I so that the water jacket W between the upper part and the lower part of the water jacket W of the cylinder block So as to enhance the separation of the cooling water flow.

Further, the guide part 100 and the sealing part 200 extend upward from the second cut surfaces 420 and 420 '.

Accordingly, the lower portion of the water jacket W of the cylinder block communicates upward between the second cut surfaces 420 and 420 '. Therefore, it is possible to further strengthen the separation cooling at the upper and lower portions of the water jacket W of the cylinder block.

At this time, the guide part 100 and the sealing part 200 are bent downward from the support part 300 closest to the first cut surface 410, 410 'toward the first cut surface 410, 410' do. As described above, since the guide portion 100 and the sealing portion 200 can act as the flow resistance of the cooling water flowing into the upper portion of the water jacket W of the cylinder block, to be. As a result, the cooling water flow at the upper portion of the water jacket W of the cylinder block is strengthened, thereby improving the performance of the engine. At the same time, the flow of the cooling water flowing into the lower portion of the water jacket W of the cylinder block is induced, thereby contributing to reduction of friction loss and improvement of fuel consumption.

The guide part 100 and the sealing part 200 are formed on one side of the inside of the water jacket surrounding the cooling water inlet side cylinder bore # 1 and on the side of the cooling water inlet side cylinder bore # Set Angle (

Figure 112016021823760-pat00004
). This is because the first cut surfaces 410 and 410 'of the guide part 100 and the sealing part 200 are bent toward the cooling water inlet I so that the water jacket W of the cylinder block, So as to enhance the separation of the cooling water flow between the upper part and the lower part.
