Accompanying drawing explanation
Fig. 1 is according to the structural representation of the idle call current divider of prior art.
Fig. 2 is according to the structural representation of idle call current divider of the present utility model.
The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 2, according to idle call current divider of the present utility model, definition has refrigerant to flow to, comprise feed liquor portion 1 and be arranged on its downstream and coupled separatory portion 2, separatory portion 2 is cast member or extrusion, comprise the spreader 21 that is arranged on its center and axially upstream extends along it and spreader 21 a plurality of tap holes 22 are around set, tap hole 22 is for installing isocon.Preferably, tap hole 22 is evenly distributed in spreader 21 around centered by knockout central shaft, makes like this in each tap hole 22 of distribution of fluid well-distributing, and the number of tap hole 22 designs as required.
Feed liquor portion 1 is flare roughly, the contraction flow region 12 and the enlarged portion 13 that according to the flow direction of fluid, are disposed with mixing portion 11 and are positioned at its downstream, described mixing portion 11, contraction flow region 12, enlarged portion 13 is formed by a hollow cylindrical tube reducing, fluid mixes in mixing portion 11, contraction flow region 12 has the structure of shrinking fluid, rate of flow of fluid is increased, enlarged portion 13 has the cavity of the taper type opening extending out, according to the flow direction of fluid, comprise successively tapering 131 and platform portion 132, the setting in tapering 131, make the fluid entering flow more stable, pressure keeps better, thereby improved the performance of current divider, and platform portion 132 is mainly used in and being fixedly connected with of separatory portion 2, separatory portion 2 can be built in platform portion 132 in whole or in part, then be welded and fixed, contraction flow region 12 with describedly mix portion 11, enlarged portion 13 is cambered surface transition, body is hollow cylindrical, its internal diameter is less than the internal diameter of mixing portion 11 and enlarged portion 13, the setting of cambered surface, can reduce resistance, the fluid that enters be flowed more stable, pressure distribution is more even, noise is little, thereby has also improved the performance of current divider, mixing portion 11 is cylindrical, in it, screen pack can be set, and filters the impurity of fluid.
Feed liquor portion 1 general copper pipe or steel lining copper line machine-shaping by hollow cylindrical, the tapering 131 of feed liquor portion 1 enlarged portion 13, contraction flow region 12, mixing portion 11 adopts automatic rotary press or instrument lathe to form by spinning reducing, it is original size that the platform portion 132 of enlarged portion 13 in feed liquor portion 1 is copper pipe or steel lining copper line, then the tapering 131 of enlarged portion 13, contraction flow region 12, mixing portion 11 is by reducing machine-shaping, whole feed liquor portion 1 can one-shot forming, secondary operations again, greatly reduce production cost, solved in background technology feed liquor portion adopt cast member repeatedly machining formed the high problem of production cost.
According to the flow direction of refrigerant shown in arrow, in refrigerant flows into current divider, in the portion of mixing now 11, fully carrying out gas-liquid two-phase mixes, after the smooth transition of arc between mixing portion 11 and contraction flow region 12, by contraction flow region 12 fluid passages, shrink, now refrigerant reduces because of the inflow area of fluid under uniform pressure condition, refrigerant flow rate is increased, further increased the heat transfer effect of current divider, also make gas-liquid mixed more full and uniform, and after contraction flow region 12 and the enlarged portion smooth transition in 13 arc-shaped transition places, in the tapering 131 of enlarged portion 13, interior mixed at high speed fluid sprays, by water conservancy diversion and the shunting action of spreader 21, at fluid, enter after enlarged portion 13, be assigned to uniformly in tap hole 22, then by tap hole 22, will mix, fluidal texture is stable, the dispensing of fluid well-distributing equivalent with good heat exchange property, complete knockout function.
