Detailed description of the invention
Below, with reference to accompanying drawing, embodiments of the present invention are described.
Fig. 1 ~ Fig. 3 represents one embodiment of the present invention.In Fig. 1 and Fig. 2, reservoir 1 comprises: housing 3, and it has fluid reservoir 2; Cold-producing medium supply is with pipe arrangement 4, and it is for fluid reservoir 2 the supply system cryogen; Cold-producing medium is discharged with pipe arrangement 5, and it is for discharging the cold-producing medium in fluid reservoir 2; Rectification element 10, it is for making the flowing of this regulation of cold-producing medium generation swirling flow come from the supply of cold-producing medium supply pipe arrangement 4; Closure member 20, it is for the lower surface of closure casing 3; Interfere prominent wall 21, itself and closure member 20 are arranged integratedly, form and stir promotion division, for stirring at above-below direction the cold-producing medium of the swirling flow form produced by rectification element 10; Drier 30, it for absorbing moisture from cold-producing medium.
Housing 3 is drums that upper surface is closed.The inner peripheral surface of fluid reservoir 2 is periphery 2a.
Cold-producing medium supply with pipe arrangement 4 from the upper surface of housing 3 to fluid reservoir 2 opening.The top end opening of cold-producing medium supply pipe arrangement 4 is refrigerant inlet 4a.Refrigerant inlet 4a is at the central opening of the upper surface of fluid reservoir 2.Cold-producing medium supply is connected with the refrigerant outlet of evaporimeter (not shown) with the other end of pipe arrangement 4.
Cold-producing medium discharge pipe arrangement 5 runs through the central authorities of closure member 20, inserts fluid reservoir 2 from the lower surface of fluid reservoir 2.The cold-producing medium discharge pipe arrangement 5 inserted is configured to the state vertical with the middle position of fluid reservoir 2.The top end opening of cold-producing medium discharge pipe arrangement 5 is refrigerant outlet 5a.Refrigerant outlet 5a is at the upper position of fluid reservoir 2, and the position opening in the inner space entering rectification element 10 a little.Cold-producing medium discharge pipe arrangement 5 is provided with spill port 6.Spill port 6 at the lower position of fluid reservoir 2, and with interfere the position opening be highly close residing for the upper surface of prominent wall 21.Cold-producing medium is discharged and is connected with the refrigerant inlet of compressor (not shown) with the other end of pipe arrangement 5.
As shown in FIG. 1 to 3, rectification element 10 is screwed on the upper surface wall of housing 3.Rectification element 10 comprises upper surface wall portion 11 and cylinder side wall portion 12.Refrigerant accepts groove 11a is provided with in the center of upper surface wall portion 11.Refrigerant accepts groove 11a is relative with refrigerant inlet 4a.Upper surface wall portion 11 is equally spaced provided with 3 convolution groove 11b, and this convolution groove 11b is communicated with refrigerant accepts groove 11a, spirally extends approximately towards radial direction.The external diameter in cylinder side wall portion 12 is set as slightly less than the inner peripheral surface of housing 3, that is, be set as the size slightly less than the periphery 2a of fluid reservoir 2.Thus, being formed at complete cycle between cylinder side wall portion 12 and the inner surface of housing 3 can for the gap d under flow of refrigerant.
Closure member 20 is substantially in discoideus component.Closure member 20 is pressed into the lower face side of housing 3.
Interfere the prominent projecting upper surface at closure member 20 of wall 21.That is, prominent wall 21 is interfered to be arranged in fluid reservoir 2.Interfere prominent wall 21 to be the cross sections extended along the radial direction of fluid reservoir 2 to be the prominent wall of trapezoidal shape.
Drier 30 is housed in the inner space 11c of rectification element 10.Refrigerant outlet 5a is position opening immediately below drier 30.
In described structure, have passed the cold-producing medium of evaporimeter (not shown), supply to fluid reservoir 2 from refrigerant inlet 4a via cold-producing medium supply pipe arrangement 4.Supply the cold-producing medium come to move from refrigerant inlet 4a at the outer surface effluent of rectification element 10.Specifically, supply from refrigerant inlet 4a the cold-producing medium come and drop to refrigerant accepts groove 11a, and cold-producing medium utilizes the mobilization force of self and its deadweight along 3 convolution groove 11b flowing.The cold-producing medium flowed in each convolution groove 11b flows along convolution direction and falls to fluid reservoir 2.Therefore, what the cold-producing medium flowed down from each convolution groove 11b was formed due to the mobilization force in direction of circling round and its deadweight makes a concerted effort, and forms the swirling flow along the periphery 2a of fluid reservoir 2 and flows down in fluid reservoir 2, producing the swirling flow of cold-producing medium in the bottom of fluid reservoir 2.
The swirling flow of cold-producing medium collides with the inclined plane 21a of the side of interfering prominent wall 21.So flow of refrigerant rises along inclined plane 21a and passes the upper surface of interfering prominent wall 21, after the upper surface through the prominent wall 21 of interference, flow of refrigerant just declines along the inclined plane 21a of the opposite side of interfering prominent wall 21.By the variation stream of this cold-producing medium at above-below direction, cold-producing medium is forced to stir in the vertical direction.By this stirring, lubricating oil is separated and is stored in the bottom of fluid reservoir 2, and cold-producing medium floats over top, thus the liquid refrigerant being mixed into lubricating oil returns from spill port, and does not have large change from the back amount that spill port returns.Gaseous refrigerant returns compressor (not shown) from refrigerant outlet 5a.
In addition, the cold-producing medium supplied to fluid reservoir 2 absorbs unnecessary moisture for dried dose 30.
As explained above, in the inner space 11c of rectification element 10, drier 30 is contained.The inner space 11c of rectification element 10 is the idle spaces of the gas-liquid separation being helpless to cold-producing medium, because at this space collecting drier 30, the gas-liquid separation not reducing cold-producing medium just achieves the miniaturization of reservoir 1.
Usually, drier more than 30 uses the particulate matter of Porous.As past case (with reference to Fig. 4), in the region that cold-producing medium in fluid reservoir 51 flows through, the drier that this particulate matter of configuration is formed in the receiving space (between 2 baffle plates 61,62) of drier, or the drier that this particulate matter is formed to be contained in sack that non-woven fabrics etc. makes and to be configured in fluid reservoir, then drier can hinder the swirling flow in fluid reservoir 2.But can not hinder the swirling flow in fluid reservoir 2 due to the drier 30 of accommodating in the inner space of rectification element 10, thus in fluid reservoir 2, cold-producing medium can circle round efficiently, and lubricating oil is stirred.So under the convolution state maintaining this cold-producing medium, make flow of refrigerant arrive the bottom of fluid reservoir 2, the interference wall 21 of dashing forward of recycling fluid reservoir 2 stirs further efficiently, makes lubricating oil be stirred fully.
Rectification element 10 has convolution groove 11b, and this convolution groove 11b flows along convolution direction owing to making to supply from refrigerant inlet 4a the cold-producing medium come.Therefore, it is possible to utilize simple formation of structure swirling flow.Utilize swirling flow that cold-producing medium can be made fully to mix with lubricating oil, and return the lubricating oil of appropriate amount to compressor.
The lateral circle surface of fluid reservoir 2 is periphery 2a.Therefore, it is possible to by successfully forming swirling flow with the synergy of rectification element 10.
(other)
In said embodiment, although stirring promotion division is formed by the interference of the projecting upper surface at closure member 20 wall 21 of dashing forward, this is not limited to, as long as can in the vertical direction to the parts that cold-producing medium stirs.Such as stir promotion division also can be arranged on the periphery 2a of fluid reservoir 2.Stir promotion division also to arrange integratedly with closure member 20, housing 3 etc., still can be provided separately.
