Definitions

  • the present invention relates to an apparatus for controlling heat transfer by placement in a groove-like flow passage provided between an inner wall and an outer wall of the cylinder block of an internal combustion engine in which a plurality of cylinders are disposed and controls heat transfer between the cooling heat medium flowing through the flow passage and the inner wall.
  • Japanese Laid-Open Patent Publication 2000-345838 describes a cooling structure for an internal combustion engine that partitions a groove-like flow passage in the cylinder block of an internal combustion engine in the axial direction of cylinders to reduce the difference in temperature in the vertical direction or the axial direction of cylinder bores in a cylinder block.
  • the cooling structure decreases the difference in temperature in the up-and-down direction of each cylinder bore by providing a difference in flow volume between an upper portion and a lower portion of the groove-like flow passage.
  • the difference in temperature in the up-and-down direction of one cylinder bore may be reduced.
  • the difference in temperature in the direction of arrangement of a plurality of cylinders cannot be reduced because the temperature of cooling water is increased while it is flowing through the cylinders.
  • Japanese Laid-Open Patent Publication 2005-315118 proposes a cooling structure that raises cooling water at a lower temperature located on lower side of the bore to the upper side of the bore per cylinder.
  • cooling water Since cooling water is partitioned among the individual cylinders, it is necessary to control flow volume of the cooling water that rises in each cylinder so that a cooling condition of the upper side of the bores in the respective cylinders is the same. Although the flow volume of the cooling water is controlled with a partition panel, high-accuracy control with the panel is quite difficult. Therefore, the difference in temperature in the direction of arrangement of the cylinders cannot be sufficiently reduced.
  • an apparatus (2) for controlling heat transfer between a cooling heat medium for cooling an internal combustion engine in which the medium flows through a groove-like flow passage and an inner wall(18, 118, 218, 318) of a cylinder block(14) of the internal combustion engine is provided.
  • the apparatus (2) is disposed in the groove-like flow passage.
  • the groove-like flow passage is provided between the inner wall (18, 118, 218, and 318) and an outer wall (20) of the cylinder block (14) housing a plurality of cylinders (#1-#4).
  • the apparatus (2) comprises includes a lower side cover (4, 104, 204, 304, 404) and a guiding member (6, 8, 106, 108, 206, 208, 306, 308, 406-409).
  • the lower side cover (4, 104, 204, 304, 404) covers a lower side of the inner wall (18, 118, 218, 318) and exposes the upper side of the inner wall (18, 118, 218, 318) to the cooling heat medium that flows from outside of the outer wall (20) through the groove-like flow passage in the direction of arrangement of the cylinders (#1-#4).
  • the guiding member (6, 8, 106, 108, 206, 208, 306, 308, 406-409) is disposed in the groove-like flow passage for upwardly guiding the cooling heat medium that flows on the outer surface of the lower side cover (4, 104, 204, 304, 404) onto the upper side of the inner wall(18, 118, 218, 318).
  • a heat transfer controlling apparatus 2 includes a lower side cover 4, guiding members 6 and 8 and partitions 10 and 12.
  • the lower side cover 4 is a part that supports the entire structure of the apparatus 2 and is made of material more rigid than those of the guiding members 6 and 8 and the partitions 10 and 12.
  • the lower side cover 4 is made of olefin resin.
  • the lower side cover 4 is shaped such that, when inserted into a water jacket 16 provided in an open deck-type cylinder block 14 of an internal combustion engine, the cover 4 is disposed in close contact with a lower portion of an inner wall 18 of cylinder block 14 while an upper portion of the inner wall 18 is left uncovered.
  • the water jacket 16 corresponds to a groove-like flow passage through which the cooling heat medium flows.
  • the length of the lower side cover 4 is shorter than the depth of the water jacket 16 and the width of the lower side cover 4 is smaller than that of the water jacket 16.
  • the lower side cover 4 is in a shape corresponding to where circles interface so as to conform to the water jacket 16.
  • the number of circles is the same as that of the cylinders (in the first embodiment, four, i.e., #1 to #4 cylinders) and the inner peripheral surface 4a of the cover 4 is substantially the same as the outer peripheral surface 18e of the inner wall 18.
  • the guiding members 6 and 8 and the partitions 10 and 12 are formed of olefinic elastomer.
  • the partitions 10 and 12 is provided at the upper end of the lower side cover 4 and have a width slight greater than that of the water jacket 16.
  • the apparatus 2 gets into close contact with the inner wall 18 and the outer wall 20 as illustrated Figs. 5 and 7 to vertically divide the water jacket 16 at the level of the partitions 10 and 12.
  • the guiding members 6 and 8 extend diagonally from one end of the partitions 10 and 12, respectively, between the outer peripheral surface 4b of the lower side cover 4 and the outer wall 20. Cooling water flows from an inlet 22 formed in the outer wall 20 into the water jacket 16.
  • the shorter guiding member 6 is positioned at upstream end of the partition 10 located on the upstream side of the cooling water.
  • the longer guiding member 8 is positioned at upstream end of the partition 12 located on the downstream side of the cooling water.
  • the cooling water flows from the inlet 22 as illustrated by the dashed line in Fig.5 and about the upper half of the cooling water, which flows on the lower side of the inner wall 18 that is covered with the lower side cover 4, is guided onto the upper side of the inner wall 18 that is uncovered with the lower side cover 4 by an inclined face 6a of the shorter guiding member 6.
  • the guided cooling water at a lower temperature reaches the cooling water at high temperature flowing on the upper side of the inner wall 18 directly from the inlet 22 to merge so that a high volume flow of merged water, the temperature rise of which is suppressed, advances downstream rapidly.
  • the longer guiding member 8 extends diagonally from the end of the partition 12 toward the opening 24 to the bottom of the water jacket 16.
  • the cooling water flow that was not guided onto the upper side of inner wall 18 by the shorter guiding member 6 at the upstream side of the partition 10 is now guided onto the upper side of the inner wall 18 by an inclined face 8a of the longer guiding member 8 to merge with the cooling water flow that flows on the upper side of the inner wall 18 from #1 to #4 cylinders.
  • This merger suppresses the temperature rise or decreases the temperature of the cooling water that has flowed over the upper side of the inner wall 18.
  • the merged cooling water flow in high volume rapidly flows on the upper side of the inner wall 18 at the back of the figure from the cylinders #4 to #1 as illustrated in Fig. 5. Then the water flow rises at the cylinder #1 toward the water flow passage on the side of the cylinder head.
  • the first embodiment as described has the following advantages.
  • the heat transfer controlling apparatus 2 does not perform a division among the cylinders about either the upper side or lower side of the inner wall 18 in which there are bores 18a-18d in the cylinder block 14.
  • the cooling water flows in the direction of arrangement of the cylinders without being divided per cylinder.
  • the lower side cover 4 covers the lower side of the inner wall 18 such that the lower side of the inner wall 18 is not exposed directly to the cooling water that flows from the outside of the outer wall 20 into the water jacket 16. Meanwhile, the upper side of the inner wall 18, in which combustion is conducted, is exposed directly to the cooling water and cooled easier than the lower side of the inner wall 18. Thus, difference in temperature in the vertical direction of each of the bores 18a-18d can be reduced.
  • the guiding members 6 and 8 are provided on the outer surface of the lower side cover 4.
  • the guiding members 6 and 8 include the inclined faces 6a and 8a, respectively, that extend longer from bottom to top as the guiding members 6 and 8 are located further downstream of the cooling water.
  • cooling water at a lower temperature is guided from the lower side to the upper side of the inner wall 18 at a plurality of points (here, two points).
  • the cooling water flowing from outside of the outer wall 20 is first guided onto the upper side of the inner wall 18 at one point by the upstream shorter guiding member 6. This suppresses the temperature rise or decreases the temperature of the cooling water on the upper portion of the inner wall 18.
  • the flow volume of the cooling water on the upper portion of the inner wall 18 is also increased.
  • the cooling at the upper side of the inner wall 18 is effectively conducted so that the difference in temperature in the up-and-down direction of each of the cylinder bores 18a-18d as well as the differences in temperature among the cylinders are reduced.
  • the cooling water at a lower temperature is guided from the lower side to the upper side of the inner wall 18.
  • the cooling water having an increased temperature that has flowed on the upper side of the inner wall 18 is merged with the guided cooling water having a relatively low temperature to suppress the temperature rise or decrease the temperature of the cooling water that has flowed on the upper side of thinner wall 18.
  • the upper portion of the bores 18a-18d can be sufficiently cooled even at the downstream of the water jacket 16 and difference in temperature among the bores 18-18d of the cylinders #1-4 can be reduced.
  • the partitions 10 and 12 that divide the water jacket 16 in the vertical direction are provided at the upper end of the lower side cover 4. Further, the opening 24 is formed between the partitions 10 and 12. The opening 24 introduces the cooling water, which is guided onto the upper side of the inner wall 18 by the guiding member 8, to the portion of water jacket 16 above the partitions 10 and 12.
  • the cooling water guided upward by the guiding member 8 can be easily moved to the space above the partitions 10 and 12, and, again, the cooling water at a lower temperature is introduced to the upper side of the inner wall 18 in the water jacket 16 to suppress the temperature rise or decrease the temperature of the cooling water that has flowed on the upper side of the inner wall 18.
  • the partitions 10 and 12 can reliably divide the cooling water flow into the lower side of the inner wall 18 that is covered with the lower side cover 4 and the upper side of the inner wall 18 that is uncovered with the lower side cover 4. This ensures the control of difference in temperature in the vertical direction of the bores 18a-18d.
  • a heat transfer controlling apparatus 102 according to a second embodiment is described as follows.
  • the apparatus 102 of the second embodiment is different from that of the first embodiment in that the upper end of the lower side cover 104 is made lower at the downstream side or back side of the water jacket 116.
  • the upper end of the lower side cover 104 becomes shorter in the direction of arrangement of the cylinders as the cooling heat medium flows further downstream at every point where the guiding members 106 and 108 are located.
  • the downstream partition 112 is disposed lower than the upstream partition 110 in the axial direction of the bores 118a-118d.
  • the length of the downstream guiding member 108 is shorter than that of the guiding member 8 of the first embodiment.
  • Other structure is the same as that of the first embodiment.
  • the cooling water flows from the inlet 122 as illustrated by the dashed line in Fig. 10 and about half of the cooling water, which flows on the lower side of the inner wall 118 that is covered with the lower side cover 104, is guided onto the upper side of the inner wall 118 that is uncovered with the lower side cover 104 by the shorter guiding member 106.
  • the guided cooling water reaches the cooling water flowing on the upper side of the inner wall 118 directly from the inlet 122 to merge so that the merged water advances downstream rapidly.
  • the guiding member 108 extends diagonally from the end of the partition 112 toward the opening 124 to the bottom of the water jacket 116.
  • the guiding member 108 guides the cooling water that has flowed over the lower side of the inner wall 118 to the upper side of the inner wall 118 and allows the cooling water to merge with the cooling water having a high temperature that has flowed on the upper side of the inner wall 18 from the cylinder #1 to the cylinder #4.
  • This merger suppresses the temperature rise or decreases the temperature of the cooling water.
  • the merged cooling water in high volume rapidly flows on the upper side of the inner wall 118 at the back of the figure, which is wider than the upper side of the inner wall 118 at the front of the figure, above the partition 112 from the cylinder #4 to #1, as illustrated in Fig. 10. Then the water flow rises at the cylinder #1 toward the water flow passage on the side of the cylinder head.
  • the second embodiment as described has the following advantage.
  • flow passage of the cooling water is wider on the upper side of the inner wall 118 or above the partition 112. In other words, cross section of the low passage is increased.
  • flow resistance of the heat medium which plays an important role in cooling the bores, on the upper side of the inner wall 118 is suppressed. Pressure loss is not increased greatly and smooth flow of the medium is maintained.
  • a heat transfer controlling apparatus 202 according to a third embodiment is described below.
  • the apparatus 202 is different from that of the first embodiment in that gaps 250 and 252 are provided between the lower side cover 204 and the inner wall 218, as illustrated in Fig. 16.
  • gaps 250 and 252 are provided between the lower side cover 204 and the inner wall 218, as illustrated in Fig. 16.
  • a step 254 extends in a radial direction of the cover 204. Accordingly, the gap 252 on the downstream side is greater than the gap 250 on the upstream side.
  • a flow-resistant panel 256 protrudes upwardly from the upper end of the lower side cover 204.
  • the upper end of the flow-resistant panel 256 is at the same level as the upper end of the inner wall 218.
  • a shorter guiding member 206 is connected to the partition 210.
  • the partition 210 is made narrower upstream of the guiding member 206.
  • a notch 210a is formed in the downstream end of the partition 210.
  • the apparatus 202 is mounted in the cylinder block 214 so that the inner side of the partition 210 contacts the outer peripheral surface of the inner wall 218. Then the notch 210a forms a communication port 258 that connects the upper side of the partition 210 with the gap 250 on the upstream side of the flow-resistant panel 256.
  • a longer guiding member 208 is connected to the partition 212.
  • the partition 212 is made narrower upstream of the guiding member 208.
  • cooling water flowing on the lower side of the inner wall 218, which has been guided by the guiding member 208, can flow into the upper space of the downstream partition 212 without being disturbed by the flow-resistant panel 256 and the partition 212.
  • cooling water which has been guided to the upper side of the inner wall 218 or above the upstream partition 210 by the shorter guiding member 206, reaches the cylinder #4 as illustrated in Fig. 17.
  • the flow-resistant panel 256 allows the cooling water to flow through the communication port 258 into the gaps 250 and 252.
  • the flow-resistant panel 256 also allows the cooling water that has flowed over the lower side of the inner wall 218 outside the lower side cover 204 to the cylinder #4 to rise and flow on the upper side of the inner wall 218 or above the down stream partition 212.
  • the third embodiment as described has the following advantage.
  • the same advantage as the two advantages described in the first embodiment can be achieved. Since the cooling water flows are exchanged, not merged, pressure loss is suppressed and smooth flow is maintained, although the flow cross-section above the upstream partition 210 and the flow cross-section above the downstream 212 are the same.
  • a heat transfer controlling apparatus 302 according to a fourth embodiment is described next.
  • the apparatus 302 of the fourth embodiment is different from that of the first embodiment in that no partitions exist.
  • Other structure is the same as that of the first embodiment.
  • the cooling water flows from the inlet 322 as illustrated in by dashed line in Fig. 20 and about half of the cooling water, which flows on the lower side of the inner wall 318 that is covered with the lower side cover 304, is guided onto the upper side of the inner wall 318 that is uncovered with the lower side cover 304 by the upstream guiding member 306.
  • the guided cooling water reaches the cooling water flowing on the upper side of the inner wall 318 directly from the inlet 322 to merge so that the merged water advances downstream while heat is transferred from the inner wall 318.
  • the guiding member 308 that extends the bottom of the water jacket 316 guides the cooling water that has flowed on the lower side of the inner wall 318 to the upper side of the inner wall 318.
  • the cooling water flowing on the upper side of the inner wall 318 from the cylinder #1 to #4 having a high temperature is merged with the cooling water having a lower temperature.
  • This merger suppresses the temperature rise or decreases the temperature of the cooling water that directly contacts the outer peripheral surface of the inner wall 318.
  • the merged cooling water then flows in the direction of arrangement of cylinders at the back of the figure from the cylinders #4 to #1 as illustrated in Fig. 20. Then the water flow rises at the cylinder #1 toward the water flow passage on the side of the cylinder head.
