Effect
In the resin heat sink lid assembled as described, by the instruments such as spanner being embedded into the center of the upper end holding component 4 and rotating, thus the screwing part 25 of holding component 4 is made to screw togather with the upper end open of connecting-tube nozzle 2 and both be connected.Now, positive valve 13 and negative pressure valve 14 become the state of closedown by the plus-pressure of spring, thus make the inside of radiator tank 1 become closed state.When the cooling water temperature of radiator tank 1 rise and pressure in radiator tank 1 become setting above time, positive valve 13 presses the first spring 11 and rises.Thus, the excessive steam in water tank and cooling water import not shown equalizing tank from gateway pipe 27 via intercommunicating pore 17.When press in radiator tank 1 again decline time, positive valve 13 is closed.
On the other hand, when making the cooling water temperature of the inside of radiator tank 1 decline when the stopping due to such as motor, the inside of radiator tank 1 becomes negative pressure.So negative pressure valve 14 presses the second spring 12 and moves downwards.Thus, water is supplied in radiator tank 1 from gateway pipe 27 via negative pressure valve 14.
In the resin heat sink lid of Fig. 1, even if suppose, in lid main body 3 with the melt-coating part 10 of valve body 5, poor sealing occurs, the tightness (sealing) between the cylinder portion inner peripheral surface of the first seal ring 15 and connecting-tube nozzle 2 is also made to be kept.And the tightness between the second seal ring 16 and neck 28 is kept.Consequently, when the temperature of radiator tank 1 rises, positive valve 13 normally plays function and rises, and when inside becomes negative pressure, negative pressure valve 14 declines.So, due to the normally action of each valve, therefore in resin heat sink lid of the present invention, even if just in case melt-coating part 10 there occurs seal failure, the function of resin heat sink lid also normally can be maintained.
Fig. 4 is the figure that the part of the valve body 5 represented in the lid made of resin of Fig. 1 is provided with the example of frangible portion 30.In the diagram, identical reference character is marked for the part identical with Fig. 1, and the repetitive description thereof will be omitted.
As shown in Figure 4, the shape being arranged at the section of the axis of the downside annular slot 22 of valve body 5 is formed as square.Make the upper corner part 22a this square peripheral wall surfaces to be formed at valve body 5 valve seat 29 the part 29a nearest with described upper corner part 22a wall thickness t be less than other parts.That is, wall thickness t is formed as, less than the wall thickness forming described square other turning perisporiums (surrounding square perisporium).Described frangible portion 30 is formed thus in this part.
As mentioned above, the part of this wall thickness t compared with other parts, from the first spring 11 grade of push valve main body 5 stress concentrate large percentage.Therefore, the damage because property deterioration year in year out causes easily is subject to.In addition, owing to reducing the wall thickness t of this part as described above, thus the degradation speed of this part is faster than other parts.Consequently, the sign of property deterioration year in year out can be confirmed rapidly and exactly.Even if when supposing to reach damage in frangible portion 30 deterioration, because frangible portion 30 is formed in the region not destroying sealing function of seal space, i.e. the inside region of seal space, therefore also can not damage the sealing function of seal space.
Fig. 5 is the figure of the example representing the receiving portion 50 be provided with for catching valve body 5 from below.When the valve body 5 forming lid made of resin departs from from lid main body 3 because damage waits, this receiving portion 50 catches valve body 5, prevents valve body 5 from falling in radiator tank 1.
It should be noted that, the combination of the lid main body 3 shown in the top of Fig. 5 and valve body 5 and hold component 4 structure, with the combination of the lid main body 3 shown in Fig. 1 and valve body 5 and to hold the structure of component 4 identical.
The below of Fig. 5 illustrates radiator tank 1 and the longitudinal section from radiator tank 1 vertical outstanding connecting-tube nozzle 2 upward.The central shaft of the radiator tank 1 position of the central shaft of the connecting-tube nozzle 2 outstanding from radiator tank 1 in Fig. 5 and Fig. 1 is inconsistent, and is partial to the left side of Fig. 5.And the inner circumferential side on the left of the deflection of connecting-tube nozzle 2 is provided with stepped part 51.
Stepped part 51 be by deflection side perisporium bending roughly 90 laterally degree after, further upward bending roughly 90 spend shape.As shown in Figure 6, by this shape, the plane of stepped part 51 is made to become a part (arc-shaped ring) for circular ring.Suppose a part for the melt-coating part 10 or ester moulding part associated with valve body 5 to damage and make valve body 5 fall into below after lid main body 3 departs from.Now, the stepped part 51 that valve body 5 is configured receiving portion 50 is caught, and therefore valve body 5 can not fall in the main body of radiator tank 1.It should be noted that, also as shown in Figure 1, under the state making the position of the central shaft of connecting-tube nozzle 2 consistent with the central shaft of radiator tank 1, stepped part 51 can be set in the inner circumferential side of connecting-tube nozzle 2.
Fig. 5 also illustrates that claw 52 is as receiving portion 50.Claw 52 is to arrange from the inner peripheral portion of connecting-tube nozzle 2 to central shaft to the mode flatly extended.In the example of fig. 5, by along the circumferential direction equally spaced arranging four circular arc plates in the position than stepped part 51 slightly by the inner peripheral portion of below, claw 52 groups is formed.As shown in Figure 5, both stepped part 51 and claw 52 also can being set as receiving portion 50, but when there is not the such skew of Fig. 5, also claw 52 grade only can being set and any one party of claw 52 or stepped part 51 is only set.
