Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a liquid separating device 100 according to an embodiment of the present invention. The liquid separation device 100 is used for dividing the fluid. In the present embodiment, the liquid separation device 100 is used in an air conditioner and separates the refrigerant. It is understood that in other embodiments, the fluid diversion apparatus 100 can also be used in other types of heat exchange fluid diversion applications such as heaters, condensers, reboilers, and the like.

The utility model discloses a divide liquid device 100 includes inlet tube 10 and divides liquid head 20. The liquid separation head 20 is provided with a liquid inlet 21 and at least two liquid separation ports 22 communicated with the liquid inlet 21.

The inlet pipe 10 may be a metal pipe such as a stainless steel pipe or an aluminum pipe, or a pipe made of a resin material or a rubber material; the inlet pipe 10 may be a flexible pipe or a hard pipe as long as it can pass the fluid and does not chemically react with the fluid.

In the present embodiment, the liquid separation head 20 is a three-way liquid separator. It is understood that in other embodiments, the liquid-separating head 20 may be a multi-way liquid-separating device, or may be a three-way pipe, as long as it has a cavity communicating one liquid inlet 21 with at least two liquid-separating ports 22, and can uniformly separate the fluid entering from the liquid inlet 21 and lead out at least two fluids, and is not limited to the three-way liquid-separating device in this embodiment.

The working principle of the liquid separation device 100 is as follows: an external fluid source (not shown) is connected to one end of the inlet tube 10, and the other end of the inlet tube 10 is communicated with the liquid inlet 21 of the liquid separation head 20. The fluid enters the liquid separating device 100 from the inlet pipe 10, and after the liquid is separated by the liquid separating head 20, at least two branch fluids are formed, and then the branch fluids are discharged from the liquid separating port 22 and enter the collecting pipe 211.

However, in the conventional air conditioning apparatus, the liquid distribution pipe is directly connected to a plurality of external fluid sources. When the pressures or flow rates of the fluids in the external fluid sources are inconsistent, the fluids entering the liquid distribution pipe have different flow rates, so that the liquid distribution pipe cannot uniformly distribute the liquids, and the heat exchange efficiency of the fluids in the heat exchange device is influenced.

In the embodiment of the present invention, the liquid distribution device 100 further includes a first distribution pipe 30 and a second distribution pipe 40, one end of the first distribution pipe 30 and one end of the second distribution pipe 40 are equally communicated with two liquid distribution ports 22 on the liquid distribution head 20, and the other end of the first distribution pipe 30 and the other end of the second distribution pipe 40 are communicated with two ends of the collecting pipe 211 respectively.

This arrangement allows the inlet tube 10 to be connected to an external fluid source, which enters the dispensing device 100 through the inlet tube 10. The fluid is separated by the liquid separation head 20 to form at least two uniform branch fluids, and the branch fluids uniformly enter the interior of the collecting main from two ends of the collecting main 211 through the first distributing pipe 30 and the second distributing pipe 40.

In one embodiment, to further ensure that the two branch fluids passing through the liquid separation head 20 can uniformly enter the collecting main 211, the first distribution pipe 30 and the second distribution pipe 40 are configured to have the same structure and the same size.

The arrangement is such that the two branches have equal conduit lengths and equal conduit cross-sectional areas, so that the two branch flows have approximately equal flow rates. After the liquid separation by the liquid separation head 20, the two paths of fluid can enter the collecting pipe 211 more uniformly. In addition, the arrangement enables the first distribution pipe 30 and the second distribution pipe 40 to be replaceable, on one hand, a set of common production equipment and tools can be designed for the first distribution pipe 30 and the second distribution pipe 40, and therefore the manufacturing cost of the liquid separation device 100 can be reduced; on the other hand, the user can purchase the spare parts of the first distribution pipe 30 and the second distribution pipe 40 in a unified manner, so as to facilitate replacement or replenishment of damaged pipes.

In one embodiment, the first distribution pipe 30 includes a first pipe segment 31, a second pipe segment 32, a third pipe segment 33, and a fourth pipe segment 34, wherein both ends of the first pipe segment 31 are respectively communicated with the liquid distribution port 22 and the second pipe segment 32, and both ends of the third pipe segment 33 are respectively communicated with the second pipe segment 32 and the fourth pipe segment 34; the second distribution pipe 40 includes a first pipe portion 41, a second pipe portion 42, a third pipe portion 43, and a fourth pipe portion 44, the first pipe portion 41 having both ends communicating with the liquid distribution port 22 and the second pipe portion 42, respectively, and the third pipe portion 43 having both ends communicating with the second pipe portion 42 and the fourth pipe portion 44, respectively.

With this arrangement, the first distribution pipe 30 and the second distribution pipe 40 have the relatively smallest number of pipe sections/portions and the relatively smallest turning angle between adjacent pipe sections/portions, i.e. the pipe sections/portions have the smallest turning width on the basis of the smaller number of pipe sections/portions, which is beneficial to reducing the resistance of the fluid flowing through the distribution pipes, especially the resistance of the fluid passing through the respective turning positions of the first distribution pipe 30 and the second distribution pipe 40.

It is understood that neither the first distribution pipe 30 nor the second distribution pipe 40 is limited to four pipe sections/pipe portions. The first distribution pipe 30 and the second distribution pipe 40 further include four or more pipe segments/pipe portions or four or less pipe portions.

With this arrangement, the turning angle between the adjacent first distribution pipe 30 and second distribution pipe 40 having four or more pipe sections/pipe portions is made smaller, and the flow resistance of the fluid passing through the respective turns is further reduced. The first distribution pipe 30 and the second distribution pipe 40 with the four or less pipe sections/pipe parts can reduce the bending times in the pipeline manufacturing process, and simultaneously reduce the accumulation of angle errors caused by multiple bending of the pipeline in the manufacturing process, thereby avoiding the large difference of the structures and the sizes of the first distribution pipe 30 and the second distribution pipe 40 and the large difference of the fluid flow in the branch.

Preferably, a bend is provided between each adjacent pipe section on the first distribution pipe 30 and each adjacent pipe section on the second distribution pipe 40. This configuration is beneficial to reduce the resistance of the fluid passing through the turning point between the adjacent pipe sections/portions of the first distribution pipe 30 and the second distribution pipe 40, so as to ensure the fluid to pass through smoothly and rapidly.

Preferably, the first distribution pipe 30 and the second distribution pipe 40 are provided as arc-shaped pipes, i.e. each part of the first distribution pipe 30 and the second distribution pipe 40 is smoothly transited. This arrangement further reduces the resistance to the flow of the fluid in the first distribution pipe 30 and the second distribution pipe 40, and reduces the attenuation of the flow velocity of the fluid when the fluid flows through the bent portion of the pipe.

So configured, while satisfying the requirement that the first distribution pipe 30 and the second distribution pipe 40 have a relatively comprehensive minimum number of pipe sections/portions and a relatively comprehensive minimum turning corner, the positioning and installation of the liquid separation device 100 in the microchannel evaporator 200 is facilitated.

In one embodiment, the first distribution pipe 30 and the second distribution pipe 40 are symmetrically arranged about the axis of the inlet pipe 10 when the liquid distribution device 100 is properly assembled.

So configured, it is possible to make two fluid branches with equal conduit length, equal conduit cross-sectional area, and equal flow resistance, so that the two fluid branches have equal flow rates. After the liquid is separated by the liquid separation head 20, the uniformity of the two branch fluids can be improved more remarkably, and the two branch fluids enter the collecting pipe 211 simultaneously.
