Description

Structure of Water Jacket Spacer {STRUCTURE OF WATER JACKET SPACER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water jacket spacer installed in a cylinder block, and more particularly, to a water jacket spacer which is formed along the entire circumference of each cylinder bore to divide the flow of cooling water into upper and lower parts, The present invention relates to a structure of a water jacket spacer capable of improving cooling performance through a water jacket spacer separating the upper channel and the lower channel with respect to a direction.

Generally, part of the heat generated in the combustion chamber of the engine is absorbed into the cylinder head, the cylinder block, the intake and exhaust valves, and the piston. If the temperature of these components excessively increases, thermal deformation may occur or the oil film on the inner wall of the cylinder may be broken to cause a lubricating failure phenomenon, thereby causing a thermal obstacle. The thermal failure of the engine causes abnormal combustion such as combustion failure, knocking, or preignition, thereby causing significant damage such as the loss of the piston, and the thermal efficiency is lowered and the output is also lowered. On the other hand, excessive cooling of the engine has problems such as deterioration of the output, fuel consumption and low temperature of the cylinder, so that it is necessary to appropriately control the cooling water temperature. In this respect, as shown in Fig. A water jacket spacer 15 is applied to the water jacket 13 of the cylinder block 10 as a mechanism for improving the fuel economy of the engine by inserting foreign matter into the water jacket 13. The conventional water jacket spacer 15 is made of a resin material and is inserted into a water jacket 13 formed along the circumference of each cylinder bore 10a of the cylinder block 10 to closely contact the lower end thereof. A flow path guide for controlling the flow of cooling water is provided outside the spacer 15 to regulate the flow rate and flow rate of the cooling water flowing to the outside and adjust the heat transfer coefficient of the engine train transmitted from the cylinder liner ) Is kept constant.

2 shows a mounted water jacket spacer 15 in which a water jacket spacer 15 is formed by inserting a water jacket 13 inside a cylinder block 10 into an upper channel C1 and a lower channel C2 The upper channel C1 induces a rapid cooling flow to induce sufficient cooling of the inter-cylinder bore and the cylinder bore top ring reverse (TRR), and the lower channel substantially stagnates the cooling water flow, The method of increasing the temperature is applied.

However, the water jacket spacer has a disadvantage in that the airtightness is poor to maintain the flow of the inter-layer coolant water hermetically when the hydraulic pressure of the coolant water is generated during engine operation.

3, the sealing member 20 of the rubber material is provided on the inner surface of the upper frame 15a of the water jacket spacer 15 to securely separate the upper channel C1 and the lower channel C2 So that the cooling water flow in the upper channel can be increased to reduce the thermal load.

However, there is a disadvantage in that the assemblability is deteriorated due to the interference due to the amount of compression of the sealing member 20 when the water jacket spacer 15 is assembled in the cylinder block.

4 is a perspective view of a water jacket spacer according to an embodiment of the present invention, and FIG. 5 is a sectional view taken along line A-A of FIG.

The water jacket spacer 100 of the present invention is intended to regulate the flow of cooling water by partitioning into a separate layer inside the water jacket 13 (see the conventional drawing), that is, an upper channel C1 and a lower channel C2.

4, the water jacket spacer 100 according to the present invention is largely formed in the same shape as the water jacket 13 formed in the cylinder block 10 (see FIG. 1). The semi- A lower frame 120 positioned on the lower side in the same shape and a lower frame 120 integrally connecting the upper frame 110 and the lower frame 120 and having a vertical support And a sealing member 200 composed of a frame 130 and provided on an inner surface of the upper frame 110 with a predetermined area.

5, the water jacket spacer 100 is inserted into the water jacket 13 so that the layer through which the cooling water flows is upwardly directed through the upper frame 110 including the sealing member 200 and the sealing member 200 And the space lower channel C2 formed in the downward direction are distinguished from each other.

First, since the water jacket spacer 100 is required to maintain its shape, it is preferable to use a material having constant rigidity and elasticity, and it is preferable that the water jacket spacer 100 is made of metal or plastic. When the water jacket spacer 100 is inserted into the inner periphery of the water jacket 13, particularly when the side cross-sectional structure of the water jacket 13 is formed in a conical shape narrowing downward, (130) presses the inner circumference of the water jacket (13) and is firmly fixed.

As shown in FIG. 4, the upper and lower frames 110 and 120 have a snowman shape, and the sealing member 200 is protruded from the inner surface of the upper frame 110 .

The sealing member 200 may be attached to the water jacket 13 through a coupling means such as a double-sided tape or an adhesive or a bolt. The sealing member 200 may have a sealing function for preventing the cooling water from flowing to the inner peripheral edge of the water jacket 13, So that it can be made of a rubber material.

The vertical support frame 130 connecting the upper and lower frames 110 and 120 is preferably made of the same material as that of the upper and lower frames 110 and 120 and a plurality of water jackets 13 ), And can be firmly supported.

A stopper 140 having a predetermined length may be installed on the outer surface of the support frame 130 so as to be protruded forward and backward.

The stopper 140 has an insertion groove 132 formed at a predetermined depth in the support frame 130. The body 141 is inserted into the insertion groove 132. The body 141 is inserted into the insertion groove 132, A spring 150 may be installed to provide a supporting force and a restoring force.

The spring 150 is generally an impact absorbing and shock absorbing product.

Further, the body 141 may be further formed with an inclined surface 142 so as to form an upper light-tight narrowing shape. That is, one side of the body 141, that is, the lower side from the upper side of the outer side, may be formed to have a smaller width.

This is to facilitate smooth insertion of the water jacket spacer 100 when it is inserted and assembled.

A protrusion 143 of a predetermined size integrally protrudes from the upper end or the lower end or the upper or lower end of the body 141 to be caught by the engaging protrusion 132a formed inside the insertion recess 132, So as to prevent escape.

The operation of the water jacket spacer 100 according to the present invention having the above-described structure is a structure in which the water jacket spacer 100 is inserted and fixed to the water jacket 13 again as shown in FIGS. Furthermore, the upper channel (C1) and the lower channel (C2) are formed in the water jacket (13) through the sealing member (200) of the water jacket spacer (100).

The flow rate of the cooling water flowing in the upper channel (C1) portion of the water jacket (13) is divided by the flow rate of the cooling water flowing in the lower channel (C2) The thermal load on the upper end of the cylinder block 10 can be reduced.

On the other hand, when the water jacket spacer 100 including the sealing member 200 is assembled in the block, the assembling property may be reduced due to the interference of the sealing member 200 protruding compared to the width in the block. The inclined surface 142 formed on the body 141 of the stopper 140 can be prevented from being brought into contact with the stopper 140 of the stopper 140 by the stopper 140. [ Slip contact with the surface to help assemble easily.

In addition, when the water jacket spacer 100 is installed, the stopper 140 is restored and positioned as close as possible to the block surface, so that a sealing effect similar to that of the sealing member 200 can be exhibited.

As described above, according to the water jacket spacer according to the embodiment of the present invention, the assembling property can be improved by the stopper 140 installed to adjust the degree of protrusion on the support frame side of the water jacket spacer, It is possible to prevent the sealing member 200 from being damaged during assembly and to seal the cylinder head in contact with the upper surface of the water jacket spacer 100 so as to be sealed so as not to alternate the cooling water between the layers of the water jacket 13 .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
