Background

In the refrigeration system, the refrigerant flows through the heat exchanger through a plurality of branches to exchange heat, for example, under the refrigeration working condition in summer, the refrigerant flowing through the indoor heat exchanger needs to be uniformly distributed to all the branches of the indoor heat exchanger, so that the heat exchanger can be ensured to be efficiently utilized. When the refrigerant is distributed unevenly, different superheat degrees can be generated at the outlets of the branch circuits of the heat exchangers, the branch circuits with less liquid supply enter the superheat region too early, the heat exchange capacity of the heat exchanger in the superheat region is greatly reduced, the heat exchange area of the branch circuits cannot be fully utilized, and therefore the heat exchange efficiency is reduced, and because the heat exchange of the indoor heat exchanger is uneven, the indoor air outlet temperature is uneven, the comfort is reduced, and the like.

When an actual refrigerating system operates, the liquid supply amount of each branch refrigerant is different, and the gas-liquid two-phase refrigerant flows into each branch unevenly.

In the prior art, two types of heat exchangers are generally used:

1. the venturi-type liquid separator (as shown in fig. 2a and 2 b) throttles by a contraction and expansion nozzle inside the liquid separator, and after the refrigerant passes through the contraction and expansion nozzle, the flow rate is increased, and the gas phase and the liquid phase are uniformly mixed. The flow line is uniform in the whole process, the pressure drop of the liquid separator is small, a pressure mutation area is formed after the speed cannot be increased, and no turbulence is generated;

2. the pressure drop type liquid separator (as shown in fig. 3a and 3 b) has a sudden shrinkage orifice at the inlet, and when the refrigerant with gas-liquid two-phase passes through the orifice, the section suddenly shrinks, the flow velocity of the refrigerant increases, and the refrigerant enters the mist region. Meanwhile, the high-speed refrigerant generates vortex under the action of the pressure difference between the front and the rear of the pore plate, so that the two-phase refrigerant is further uniformly mixed.

As shown in fig. 4 to 5b, for solving the problem that the current knockout inner structure is complicated, the processing cost is high, mix not enough evenly, the utility model discloses a knockout 1 is including dividing liquid cavity 11, divides the both sides of liquid cavity 11 to be provided with inlet 111 and a plurality of liquid outlet 112 respectively, knockout 1 is still including dividing liquid component 12, divides liquid component 12 fixed connection in the inboard that divides liquid cavity 11, divides liquid component 12 to be network structure, network structure's different regional net mesh number is not completely unanimous for the velocity of flow is different after the network structure is flowed through to the fluid, and then produces the turbulent flow, makes the fluid homogeneous mixing. It should be noted that the mesh numbers mentioned above are not all the same, and it should be understood that in the different regions (at least two regions) into which the liquid separation member 12 is divided, the mesh number of at least one of the regions is different from the mesh number of the other regions.

For example, in the first embodiment, as shown in fig. 5a and 5b, the liquid separation member 12 is in a shape of a disk, an annular protrusion 121 is disposed on the edge of the disk, an annular groove (not shown) is disposed in the liquid separation cavity 11, and the annular protrusion 121 is inserted into the annular groove, so that the liquid separation member 12 and the liquid separation cavity 11 are fixedly connected. The disc is distributed with a plurality of circular rings, the mesh number of two adjacent circular rings is different, and the mesh number of the adjacent circular rings is alternatively distributed from the center to the edge.

The setting mode has the advantages that: through setting up liquid distribution member 12, replaced the conventional pipeline that has the shape requirement of making in dividing liquid cavity 11, made the utility model discloses a structure is simplified greatly, and processing cost also reduces correspondingly to, owing to divide the special design of the different regional different net mesh numbers of liquid distribution member 12, make the misce bene degree become can control. Specifically, as shown in fig. 5b, due to the different mesh numbers of the adjacent rings on the liquid separating member 12, the resistance received by the refrigerant flowing through the liquid separating member 12 is also different, in a conventional case, after the refrigerant with high flow rate flows through the rings with different mesh numbers, a speed difference is generated between two adjacent streams of refrigerants, and a pressure difference is generated between different streams of refrigerants due to the different flow rates, so that the refrigerants with different pressure differences are converged to generate turbulence, the refrigerants are fully mixed, and then enter different liquid outlets 112, and uniform mixing of the refrigerants is further realized. Because the mesh number is adjustable, technicians in the field can reasonably set different annular mesh numbers according to different refrigerant flow rates and flow velocities, in a preferred embodiment, the value range of the mesh number is 18-100 meshes, when the mesh number is smaller than 18 meshes, the influence of the mesh on the flow velocity is very small, the effect of turbulence is difficult to play, when the mesh number is larger than 100 meshes, the influence of the mesh on the flow velocity is too large, the blocking influence on normal flow is generated, the reverse effect is played, and the mesh number is not suitable at this moment.

The setting mode has the advantages that: by adopting the mesh distribution, the refrigerant presents the conditions of high edge flow velocity and low intermediate flow velocity, the flow velocity difference between the integral edge refrigerant and the central refrigerant is larger at the moment, and the pressure difference is correspondingly larger, so that the turbulent flow is more favorably formed, and the refrigerant is more uniformly mixed.

Embodiments three, four, and five of the present invention will be described with reference to fig. 7a to 9.

As shown in fig. 7a to 7c, the liquid separating member 12 is in a frustum shape, a cone shape, a hemisphere shape, or a semi-ellipsoid shape, and the common feature is that the liquid separating member 12 is not in a structure on a horizontal plane, but the whole body has a three-dimensional structure, as shown in fig. 7a, the installed liquid separator 1 is shown in fig. 8, the refrigerant flow direction is as shown in fig. 9, on the basis of controlling the mesh number and mesh wire thickness, due to the change of the structure, part of the refrigerant flow direction is changed, and the refrigerant impacts the inner wall of the liquid separating cavity 11, so as to achieve better turbulence effect, and the skilled in the art can adjust the turbulence effect through the mesh number, mesh wire thickness, and the whole structure of the liquid separating member 12, thereby greatly improving the plasticity of the structure, so that the skilled in the art can find a better design, so that the turbulent flow can be achieved, and the processing is easier, the production cost is lower, and the market competitiveness is stronger. In addition, the three-dimensional design also enables the surface area of the net-shaped structure to be larger, the cutting of the refrigerant fluid to be more obvious, and the control capability of the thickness of the net wire to be enhanced.

Particularly, the material of the liquid separating member 12 is metal or nylon, and the production of the material as a net structure is common, so that the production cost is saved.

To sum up, the utility model discloses an adjust mesh number, net silk thickness and overall structure who divides liquid component 12, realized the stability control of turbulent degree, because control parameter is many, bigger to the design space of knockout 1, manufacturing cost also descends very big, can also play certain refrigerant filtering action, kills many birds with one stone.

It should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can adjust the above-mentioned structure without deviating from the principle of the present invention, so that the present invention can be applied to more specific application scenarios.

For example, in an alternative embodiment, the fixing connection mode of the liquid separation member 12 and the liquid separation cavity 11 is obviously not limited to the matching of the annular protrusion 121 and the annular groove, and other modes such as clamping groove snap-fit, screw-fit, welding, etc. are all possible as long as the liquid separation member 12 and the liquid separation cavity 11 can be fixedly connected, and these do not deviate from the principle of the present invention, and therefore all will fall within the protection scope of the present invention.

For example, in another alternative embodiment, the liquid separating member 12 is not limited to the above-described disc-shaped, frustum-shaped, etc., as long as it can reasonably fit the inner dimension of the liquid separating cavity 11, which does not deviate from the principle of the present invention, and thus all will fall within the protection scope of the present invention.

Furthermore, the utility model also provides an air conditioner, this air conditioner has the knockout 1 in any embodiment of the aforesaid.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
