Description

A kind of multi-point injection separating tube

Technical field

The utility model relates to the technical field of separating tube more particularly to a kind of multi-point injection separating tubes.

Background technique

Large-size air conditioning and industrial refrigeration equipment mostly use distributed heat removal device to design；A wherein very crucial components It is exactly coolant liquid dispenser.Traditional dispenser is processed by the way of CNC, bend pipe and welding.It is limited in liquid separation structure design Too much, leading to some drawbacks commons is exactly liquid separation unevenness, and it is big that cooling liquid speed slows down the pressure loss.

Utility model content

The purpose of this utility model is to provide a kind of multi-point injection separating tube for above-mentioned status.

The technical solution adopted in the utility model: a kind of multi-point injection separating tube, including input duct and liquid outlet pipe and Separating tube, in which:

The input duct is cylindrical shape, and internal have a first passage extended along first axle direction, described first Axis is consistent with the length direction of the main pipeline, and the first passage is the narrow infundibulate in the wide centre in both ends；

The liquid outlet pipe has multiple circumferentially distributed second channels, and the second channel is set along institute's second axis It sets, forms acute angle between the second axis and the first axle, the internal diameter of the second channel is from liquid feeding end to outlet end Uniformly reduce, so that the second channel be made to form pyramidal structure, the outlet end of each second channel connects a liquid separation Pipe.

The beneficial effects of the utility model are: first passage is the narrow infundibulate in the wide centre in both ends, increase spray can be played The flow velocity of injection pressure and coolant liquid, and be easy to generate vortex phenomenon, while second channel is circumferentially distributed and opposite main pipeline It is obliquely installed, so that liquid is more uniformly entered second channel, and second channel 20 is pyramidal structure, further increases injection Pressure and cooling liquid speed.

Detailed description of the invention

Attached drawing involved in the utility model embodiment description is simply introduced, in order to the utility model reality It applies the technical solution in example to be become apparent from, completely illustrated, some implementations of following attached drawing only for the utility model Example, is not intended to limit the utility model, under the premise of without other creative works, it is clear that can be according to these attached drawings Obtain other accompanying drawings.

Fig. 1 is the schematic diagram of multi-point injection separating tube.

Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model Limitation.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection.It can be mechanical connection, be also possible to be electrically connected.Can be directly connected, can also indirectly connected through an intermediary, It can be the connection inside two elements or the interaction relationship of two elements.For those of ordinary skill in the art and Speech, can understand the concrete meaning of above-mentioned term in the present invention as the case may be.

In the present invention unless specifically defined or limited otherwise, fisrt feature the "upper" of second feature or it "lower" may include that the first and second features directly contact, and also may include that the first and second features are not direct contacts but lead to Cross the other characterisation contact between them.Moreover, fisrt feature includes above the second feature " above ", " above " and " above " One feature is right above second feature and oblique upper, or is merely representative of first feature horizontal height higher than second feature.First is special Sign includes fisrt feature right above second feature and oblique upper under the second feature " below ", " below " and " below ", or only Indicate that first feature horizontal height is less than second feature.

Such as Fig. 1, the utility model provides a kind of multi-point injection separating tube, including input duct 1 and liquid outlet pipe 2 and liquid separation Pipe 3,

Input duct 1 is cylindrical shape, internal to have the first passage 10 extended along the direction first axle L1, first axle L1 is consistent with the length direction of input duct 1, and first passage 10 is the narrow infundibulate in the wide centre in both ends；

Liquid outlet pipe 2 has multiple circumferentially distributed second channels 20, and second channel 20 is arranged along second axis L2, the Sharp angle α is formed between two axis L2 and first axle L1, the internal diameter of second channel 20 uniformly reduces from liquid feeding end to outlet end, from And second channel 20 is made to form pyramidal structure, to further increase injection pressure and cooling liquid speed, each second channel 20 Outlet end connects a separating tube 3.

The multi-point injection separating tube according to the present embodiment, first passage are the narrow infundibulate in the wide centre in both ends, can be with The flow velocity for increasing injection pressure and coolant liquid is played, and is easy to generate vortex phenomenon, while second channel is circumferentially distributed simultaneously Opposite main pipeline is obliquely installed, and so that liquid is more uniformly entered second channel, and second channel 20 is pyramidal structure, into one Step increases injection pressure and cooling liquid speed.

Further, the liquid feeding end of second channel 20 has the curved edge connecting with the edge-smoothing of first passage 10, liquid Body, which enters second channel 20 along the inner wall of first passage 10, to be hindered, and liquid inlet stream resistance is further decreased.

Further, the range of sharp angle α is formed between second axis L2 and first axle L1 are as follows: 30~40 °.On the one hand it prevents Obstruction of the coolant liquid when entering liquid outlet pipe 2 is excessive to be caused to flow back, and another convenience is preferable to obtain water conservancy diversion.

Preferably, liquid outlet pipe 2 is circumferentially arranged with eight second channels 20.

Further, the outlet end of second channel 20 is equipped with internal screw thread, and is threadedly coupled with separating tube 3.

Further, input duct 1 and liquid outlet pipe 2 are all made of LSM metallic print technology and are processed.

The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, all in the utility model Spirit and principle within, any modification, equivalent replacement, improvement and so on should be included in the protection model of the utility model Within enclosing.
