Abstract

The utility model relates to a flow divider, which comprises a flow divider body (1), a main passage (3) and a plurality of flow dividing passages (2), wherein the main passage (3) and the flow dividing passages (2) are arranged in the flow divider body (1), the flow dividing passages (2) are respectively communicated with the main passage (3), and a conical bulge (4) is arranged in the center position of an inner wall (1.1) of the flow divider body (1) arranged at the tail end of the main passage (3). Compared with the prior art, the flow divider has the advantages that the conical bulge is arranged in the middle position of the inner wall of the flow divider body arranged at the tail end of the main passage, i.e. the top part of the conical bulge is positioned on the same straight line as the axial line of the main passage, fluid flowing in the main passage can realize the uniform flow dividing along the conical surface under the effect of the conical bulge, the fluid after the flow division can be uniformly divided into each flow dividing passage, simultaneously, the fluid is uniformly divided along the conical surface without being buffered, and the internal turbulence phenomenon of the fluid cannot easily occur, so the fluid can be uniformly divided into the flow dividing passages by the flow divider, and in addition, the internal turbulence phenomenon of the fluid can be reduced.

Description

Current divider

Technical field

The utility model relates to a kind of current divider that is used for aircondition.

Background technology

At present; The current divider of prior art is as shown in Figure 1; Comprise a main channel 3 ' and a plurality of split channels 2 ' are set on current divider body and the current divider body 1 ', a plurality of split channels 2 ' all are communicated with main channel 3 ', because the inwall of the current divider body 1 ' of 3 ' end, main channel is the plane; After then fluid gets into the inwall of the current divider body 1 ' of running into 3 ' end, main channel from main channel 3 '; Be diverted to again in each split channel 2 ',, have the problem of fluid shunting inequality and fluid internal turbulence phenomenon so fluid is uneven through the fluid in each split channel 2 ' of shunting back, plane.

The utility model content

The utility model provides a kind of current divider that can fluid evenly be shunted and can reduce fluid internal turbulence phenomenon to above problem.

The utility model overcomes the above problems used technical scheme: a kind of current divider with following structure is provided; It comprises the current divider body and is located at the intrinsic main channel of current divider and a plurality of split channel; Described split channel all is communicated with the main channel, and terminal current divider inner body wall centre position, described main channel is provided with conical protrusions.

After adopting above structure, compared with prior art, the utility model is because terminal current divider inner body wall centre position, main channel is provided with conical protrusions; The axis of tip and main channel that also can be regarded as conical protrusions is on same straight line; The fluid of then coming in the main channel is shunted along coned face under the conical protrusions effect uniformly, and the fluid after the shunting can be diverted in each runner uniformly; Fluid is just directly shunted along coned face without buffering uniformly simultaneously; Fluid just is not prone to the internal turbulence phenomenon yet, so the utility model can be diverted to fluid in the split channel uniformly, and can reduce fluid internal turbulence phenomenon.

As improvement; Be provided with the guide ring of conflux in the described main channel; The axis of described guide ring through hole and the axis of conical protrusions are on same vertical line, and the axis of tip and guide ring through hole that also can be regarded as conical protrusions is on same straight line, and then the fluid in the main channel will be earlier by after the guide ring conflux; Shunted by conical protrusions again; So just make that the fluid in the main channel is better by the efficient of conical protrusions shunting, then therefore also just more even by the conical protrusions shunting can make that the utility model is diverted to fluid in the split channel more uniformly.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing.

A kind of current divider as shown in Figures 2 and 3; It comprises current divider body 1 and is located at the main channel 3 and a plurality of split channels 2 (this example is four) in the current divider body 1; Described split channel 2 all is communicated with main channel 3; 3 terminal current divider body 1 inwall 1.1 centre positions, described main channel are provided with conical protrusions 4; The axis of tip and main channel 3 on top that also can be regarded as conical protrusions 4 is on same straight line; The center that so just can guarantee the fluid of 3 entering from the main channel is when flowing to the apical location of conical protrusions 4, and the tip of conical protrusions 4 is just in time run in the center of cross section, thereby makes fluid evenly shunted by conical protrusions 4.

Be provided with the guide ring 5 of conflux in the described main channel 3; The axis of described guide ring 5 through holes and the axis of conical protrusions 4 are on same vertical line; Just colliding with the tip, top of conical protrusions 4 in the center of the fluid that this can guarantee to come out from guide ring 5 through holes, guarantees that the fluid bundle can evenly be shunted by conical protrusions 4.

During installation, only need earlier guide ring 5 to be put into main channel 3, pipeline welding afterwards is identical with the conventional method of prior art, this just no longer tired stating.

Above embodiment is merely the preferred embodiment of the utility model, and the utility model is not limited only to above embodiment and also allows other structural change, allly in the utility model rights to independence claimed range, changes, and all belongs to the utility model protection domain.

Claims

1. current divider; It comprises current divider body (1) and is located at main channel (3) and a plurality of split channel (2) in the current divider body (1); Described split channel (2) all is communicated with main channel (3), it is characterized in that: described main channel (3) terminal current divider body (1) inwall (1.1) centre position is provided with conical protrusions (4).

2. current divider according to claim 1 is characterized in that: be provided with the guide ring (5) of conflux in described main channel (3), the axis of described guide ring (5) through hole and the axis of conical protrusions (4) are on same vertical line.
