Embodiment
Fig. 1 has shown heat exchanger 22, and banjo lubrication oil strainer 24 or similar fluid means are installed on this heat exchanger 22.Heat exchanger 22 comprises the clack valve assembly 20 and the heat exchange elements 28 of the preferred embodiment of the present invention.Preferably, heat exchanger 22 is annular lube oil cooler, but it also can be the heat exchanger of any other type or the fluid means of other type arbitrarily.In this manual, the definite form of heat exchange elements 28 and banjo lubrication oil strainer 24 is not a part of the present invention.
Heat exchanger or annular cooler 22 are used for coolant circuit and lubricated or other fluid circuit, and as shown in Figure 2, for example are installed on the threaded pipe 26, and this threaded pipe 26 is installed on the engine block 27 (only local expression among Fig. 2).Extend in gap or hole 29 that threaded pipe 26 passes in the heat exchanger 22, so that can subsequently lubricating oil filter 24 screw threads be installed on the pipe 26, as shown in fig. 1, also makes heat exchanger 22 be held in place on engine block 27.
Preferably as shown in Figure 3, heat exchanger 22 comprises heat exchange elements 28, and this heat exchange elements 28 has end plate 31, top panel 30 and the middle clack valve assembly 20 between them.Heat exchange elements 28 is a stacked-plate type, and coolant inlet 32 and coolant outlet 34 are arranged.Heat exchange elements 28 by soldering together aluminium sheet and form.Isolated arcuate openings is arranged in each plate, and these register are so that form each flow channel or chamber or manifold 36,40.One in these manifolds can be inlet manifold, and for example manifold 36.Another manifold can be an outlet manifold 40, but also can be opposite.
When manifold 36 was inlet manifold, lubricant oil received in the manifold 36 by hole 37 (see figure 2)s that are formed in the engine block 27.This lubricant oil to outlet manifold 40, upwards enters lubricating oil filter 24 by heat exchange elements 28 then, finally is downward through pipe 26, so that return engine body 27.But, when this flow inversion, it can enter manifold 40 then by pipe 26 upwards to filter 24, to manifold 36, passes through hole 37 then, so that return engine by heat exchange elements 28.
Should be known in that heat exchange elements 28 is ordinary construction, therefore, have only and understand the shown in the drawings and introduction here of these components lists required for the present invention.
When the flow of lubricant of heating is pressed into inlet manifold 36, and freezing mixture spreads when giving coolant inlet 32, and 40 places produce the flow of lubricant of cooling at the outlet manifold, and produce the freezing mixture stream of heating at coolant outlet 34 places.Should flow also can be opposite.
Introduce clack valve assembly 20 below, can see, it comprises main body or flapper support structure 54 and resilient flapper valve 52, and this resilient flapper valve 52 is made of spring steel.Flapper support structure 54 is arranged between each heat exchange elements 28 and the panel 30 and is fixed on above them, and fluid flow port part 58 is arranged, and this fluid flow port part 58 defines passage or the valve opening 60 that is used for connection between inlet manifold 36 and panel opening 46.For clear, fluid flow port part 58 should be understood to main supporting structure 54, directly surround the part of valve opening 60.
As among Fig. 4 best shown in, flapper support structure 54 comprises a pair of plate 76,78.Plate 76 has common aluminum alloy to form, and plate 78 is formed by braze clad aluminium.Rivet or sell 62 the first head part 80 and pin or bar 82 are arranged, this pin or bar 82 pass the hole 84 that is formed in the plate 76 and extend.Plate 78 has recess 88, and this recess is communicated with hole 84, and is sized to receive the first head part 80 of rivet 62, and like this, rivet 62 is blocked or catches plate 76,78 by this.But, recess 88 can form the countersink in plate 76 bottom sides, and below hole 84, and plate 78 is flat plate, so that block and keep rivet 62 in place.Recess 88 can also be formed in two plates 76,78 part.
Fig. 5 has shown that opening 46 for example can be extended by having string section 47.This will open so that provide greater room to discharge flow of lubricant when allowing bypass flow at clack valve 52, and reduce pressure and fall.
As in Fig. 6 and 7 best shown in, the second head part 64 is knocked or be deformed into to pin 62 upper distal end.In Fig. 3, in order to represent the arrangement of each parts better, the second head part 64 is turned up the soil at interval with pin 62 and is represented by dotted lines, but selling the 62 and second head part 64 in fact forms one, as shown in Fig. 6 and 7.Like this, clack valve 52 is kept by rivet 62 or catches, rather than fastening piece for example screw or bolt.The free end portion 70 of clack valve 52 since flexible and can first or closed position (in the mode that overlaps with valve opening 60 or cover valve opening 60 against fluid flow port part 58, as shown in Figure 6) and second or open position (spaced apart on valve opening 60, as shown in Figure 7) between the motion.Free end portion 70 is of a size of like this, when being arranged in its first or closed position, will limit (more particularly prevention substantially) and flow through passage 60.But, when hope has some nonvolatil bypass flows, the size of free end portion 70 only will be arranged to partly close valve orifice.
Even also having represented the thickness of plate 30, Fig. 6 to 7A when clack valve is opened, also can make clack valve 52 can be recessed into or be hidden in the inside of opening 46.This provides smooth (clean) or smooth surface 42 on panel 30, be used for for example filter 24 of assembly, perhaps is used for heat exchanger 22 is installed in other object (for example motor).This is protection clack valve in when transportation and when being assemblied in heat exchanger 22 on other parts also.
Under normal operation (wherein, relatively heat, that fundamental freedom flows oil is transmitted to inlet manifold 36), the bias voltage that is provided by spring steel clack valve 52 or its mounting end part 68 makes the free end portion 70 of clack valve 52 be held against fluid flow port part 58, so that valve opening 60 is flow through in restriction or prevention.Like this, the most of fluid that arrives inlet manifold 36 with heat exchange relationship through heat exchange elements 28 to outlet manifold 40, thereby the freezing mixture in the heat exchange element 28 conducts heat in this is handled.Then, lubricant oil through the outlet in the panel 30 or opening 44 to lubricating oil filter 24 so that filter, and return oil circuit subsequently in normal way.
On the contrary, (for example motor starts under the arctic weather situation relatively in some cases, wherein, lubricant oil is relatively than the cold-peace toughness), the pressure drag between inlet manifold 36 and outlet manifold 40 is relatively large, therefore, the lubricant oil of viscosity forces the free end portion 70 of clack valve 52 to leave fluid flow port part 58, shown in Fig. 6,7 orders, like this, lubricant oil flows through valve opening 60 and opening 46 directly to filter 24 from inlet manifold 36.In oil circuit, periodically or instantaneous pressure peak or jet flow also walk around heat exchange elements 28 like this.
The mechanical features of clack valve 52 is chosen as the running parameter that is fit to heat exchange elements and lubricating loop (clack valve 52 is used for them), as known to persons of ordinary skill in the art.
Aforementioned structure has special advantage, and when needs cooled off, it obtained higher relatively cooling performance under normal operation, because all lubricant oil all pass through heat exchange elements substantially, so that conduct heat to freezing mixture in this case.Simultaneously, structure has been avoided the shortage fluid of mechanical part under normal instantaneous high pressure situation, for example when cold weather startup, it has also avoided metal fatigue (this metal fatigue possibility is because the pressure peak in the thin-walled part that forms heat exchange elements), because produce bypass flow in this case.
In the assembling of heat exchanger 22, flapper support structure 54 permanent being installed on heat exchange elements or other fluid means 28, and valve opening 60 is communicated with (wishing the fluid stream that this flow chamber of control flows out) with flow chamber.Rivet or sell 62 and cross out from supporting structure 54.Flapper support structure 54 permanently is installed on the fluid means 28, preferably by soldering, preferably carry out in the parts soldering together of fluid means 28, but baffle arrangement 54 can otherwise be installed.Then, the mounting end part 68 of clack valve 52 places its working position.Just, bottom wherein porose 72, clack valve 52 is arranged on the rivet 62 that offsets with main body 54.Then, head 64 distortion of rivet 62 are so that be held in place clack valve 52.
Below with reference to Fig. 6 A and 7A, represented another preferred embodiment among the figure, wherein, main body or flapper support structure 54 and pin or rivet 62 form as one (not having head 80), are preferably formed by aluminium.Supporting structure 54 is arranged to stacked relation between panel 30 and heat exchange elements 28.Then, assembly carries out brazing operation, roughly as mentioned above, so that supporting structure 54 is fixed on the fluid means 28.Then, clack valve 52 operation is positioned on the rivet 62, and the head 64 of pin or rivet 62 is out of shape, so that clack valve 52 is held in place.
Although by the agency of the preferred embodiments of the present invention, should be known under the situation that does not break away from the spirit or scope of the present invention and can carry out various variations said structure.
At first, be used for heat exchanger, should be known in that the present invention is not limited thereto although clack valve component table described here is shown, and can be used to have flow chamber any fluid means of (hope has the intermittent flow that flows out from this flow chamber).
When fluid means was heat exchanger, dissimilar heat exchangers also can fall within the scope of the present invention.For example, can use not heat exchanger as annular type.Also have, heat exchanger must not formed by pile plate, must not make the mutual soldering of each parts yet.Also have, panel 30 is not necessary, and main body self can be arranged to and lubricating oil filter or other fluid means coupling arbitrarily.
As another version,, also can replace by the elasticity bimetal strip at an easy rate although the clack valve of preferred embodiment is made of simple spring steel bar.At this moment, clack valve will be opened under cold mobility status usually, and close under normal operation.Certainly, the bimetal clack valve can also have flexibility, even and also provide the pressure peak protection under than the heat flow situation.Clack valve can also be made by other material, plastics for example, and it can apply when needed, so that improve its sealing characteristics.
Also have, although shown in preferred embodiment in, clack valve be used for its free end be arranged in first or stop substantially during closed position mobile, must be like this.For example, the size of free end portion can only partly cover passage, thereby can both measure bypass flow if having time in institute.
In the embodiment shown in Fig. 2 to 7, rivet can be made by elastic material, and this material has preformed head 64 and 80, and stretches out after supporting structure 54 solderings are on heat exchange elements 28 or block in place.
At last, flapper support structure or main body 54 can be carried out different location and orientation on the fluid means that it is installed.For example, when oil flow direction was reverse, it was at first by filter 24, and by heat exchange elements 28, as mentioned above, clack valve assembly 20 will turn upside down then, and like this, clack valve 52 will inwardly open in the flow channel or manifold of device.Clack valve 52 also can be arranged in outlet passage or manifold, rather than in inlet manifold.
As mentioned above, it will be appreciated by those skilled in the art that scope of the present invention is only limited by the accessory claim that specially proposes.
