Embodiment
Below, with reference to accompanying drawing, embodiment of the present utility model is described.
But the utility model is not limited by the record in this mode of execution.Size relationship in each figure (length and width etc.) does not reflect size relationship in kind yet.
First, with reference to Fig. 1～Fig. 3, the automobile expansion tank 100 of a mode of execution of the present utility model is described.
As shown in Figure 1, automobile expansion tank 100 possesses, and for example, for laying in water tank main body 1 and the mounting or dismounting of cooling liquid (, long-acting liquid coolant), is mounted freely on the lid 2 in water tank main body 1.This automobile expansion tank 100 is loaded in the engine compartment of automobile etc., and when the coolant temperature of the cooling unit (omitting diagram) of internal-combustion engine changes, the Volume Changes of 100 pairs of caused cooling liquids of temperature variation of this automobile expansion tank absorbs.Particularly, in the situation that the coolant temperature of cooling unit rises and make the internal pressure of cooling unit increase, the cooling liquid of cooling unit is discharged in automobile expansion tank 100; In the situation that the coolant temperature of cooling unit reduces and the internal pressure of cooling unit is reduced, the cooling liquid being discharged in automobile expansion tank 100 turns back in cooling unit again.
Water tank main body 1 comprises, the case shape 1a of portion of deposit cooling liquid and the cylindrical portion 1b forming in the upper end portion of the case shape 1a of portion.
As shown in Figure 2 and Figure 3, at the cylindrical portion 1b of water tank main body 1, be formed with the water filling hole 11 extending along short transverse (Z direction).For convenience of description, in Fig. 2, omitted lid 2(with reference to Fig. 3) diagram.Water filling hole 11 is formed, and upper end portion can be by lid 2(with reference to Fig. 3) sealing; Underpart with the case shape 1a(of portion with reference to Fig. 1) be communicated with.This water filling hole 11 is for to the interior supplementary cooling liquid of water tank main body 1.
In addition, on the top of the cylindrical portion 1b of water tank main body 1, be formed with exhaust port 12.Exhaust port 12 is formed, and along short transverse, extends, and the inside of water tank main body 1 is communicated with outside.This exhaust port 12 is for discharging cooling liquid when water tank main body 1 is overflowed in cooling liquid.In addition, the upper end portion 121 of exhaust port 12 is configured on the position lower than the upper end portion of cylindrical portion 1b.
Near exhaust port 12, dispose partition wall 13.Partition wall 13 is formed curve form.This partition wall 13 is separated water filling hole 11 sides and exhaust port 12 sides.Particularly, partition wall 13 is formed and overlooks as forniciform tabular.Therefore, while overlooking, the top of cylindrical portion 1b is circular, and is separated the region ovalize of exhaust port 12 sides that wall 13 is separated out.That is, protrude to side on the top of cylindrical portion 1b, and the part of this protrusion is separated wall 13 to be separated, and is configuring exhaust port 12 in the space being separated out.
In addition, partition wall 13 is formed, and the upper end portion along short transverse from cylindrical portion 1b extends near the underpart of exhaust port 12.Thus, the space that is separated exhaust port 12 sides that wall 13 is separated out comprises in short transverse, from the space till upper end portion to the upper end portion 121 of exhaust port 12 of cylindrical portion 1b; And the space 14(corresponding with exhaust port 12 is with reference to Fig. 3).Wherein, space 14 is to form the outer circumferential face of cylindrical part of exhaust port 12 and the space between partition wall 13.
On partition wall 13, be formed with an interconnecting part 131 that water filling hole 11 sides are communicated with exhaust port 12 sides.Interconnecting part 131 has the case shape 1a(of portion of water tank main body 1 with reference to Fig. 1) inner region and the function that is separated the regional connectivity of exhaust port 12 sides that wall 13 is separated out.This interconnecting part 131 is formed the otch extending along short transverse, and the length in the short transverse of the length of this otch and partition wall 13 is identical.In other embodiments, also can on partition wall 13, offer a plurality of such interconnecting parts 131, in addition, also can make the length in the short transverse that is shorter in length than partition wall 13 of interconnecting part 131.
So, by offer partition wall 13 near exhaust port 12, when automobile vibration causes the liquid fluctuating of cooling liquid and cooling liquid is splashed, the cooling liquid of splashing can be separated wall 13 and block, thereby, can prevent that cooling liquid is splashed to exhaust port 12 and situation about spilling from exhaust port 12.In addition, in the situation that cooling liquid is overflowed from water tank main body 1, cooling liquid can be discharged to below from exhaust port 12 via the interconnecting part 131 on partition wall 13.That is, in the situation that surpass the capacity of automobile expansion tank 100, only can in right amount cooling liquid be discharged, and can (not exceed and need ground) too much, cooling liquid not discharged.Further, because partition wall 13 is formed curve form, thus can make the liquid fluctuating of cooling liquid reduce, thus prevent that cooling liquid from spilling from exhaust port 12.
In the utility model, show the example of the interconnecting part 131 that forms incision-like on partition wall 13, but be not limited to this, the 1st variation that also can be is as shown in Figures 4 and 5 such, forms the interconnecting part 131a of circular hole on partition wall 13a.In the 1st variation, on the position of the upper end portion 121 lower than exhaust port 12, formed an interconnecting part 131a.But also can on the position of the upper end portion 121 higher than exhaust port 12, form interconnecting part 131a, interconnecting part 131a can be also a plurality of.The shape of the interconnecting part in other words, forming on partition wall and number can be diversified.
In addition, in the utility model, show partition wall 13 and be formed near the example underpart that upper end portion along short transverse from cylindrical portion 1b extends to exhaust port 12, but be not limited to this, also the 2nd variation that can be is as shown in FIG. 6 and 7 such, makes the upper end portion of partition wall 13b along short transverse from cylindrical portion 1b extend to the upper end portion 121 of exhaust port 12.In the case, be also formed with the plate-like portion that the underpart of partition wall 13b is connected with the upper end portion that forms the cylindrical part of exhaust port 12.That is, can not form space 14(with reference to Fig. 3).In addition, in Fig. 6 and Fig. 7, show the example of the interconnecting part 131b that forms circular hole on partition wall 13b, but be not limited to this, also can on partition wall 13b, form the interconnecting part (omitting diagram) of incision-like.
In addition, in the utility model, show the example that exhaust port 12 and partition wall 13 are set at the cylindrical portion 1b of water tank main body 1, but be not limited to this, also can exhaust port and partition wall be set in the case shape portion of water tank main body.
