Description

Distributor and air conditioning equipment

Technical Field

The utility model relates to a refrigeration technology field especially relates to a distributor and air conditioning equipment.

Background

In the field of refrigeration technology, a distributor is usually installed at the inlet of a heat exchanger for uniformly distributing a fluid medium in a gas-liquid two-phase to each pipe of the heat exchanger. The gas-liquid two-phase fluid medium entering the distributor is influenced by gravity, and the laminar flow condition often occurs, and if the fluid medium is directly distributed, the non-uniform distribution condition of the fluid medium in the distributor is easily caused.

Existing dispensers typically include jack dispensers, venturi dispensers and conical jack dispensers. The jack type distributor is simple in structure, small in processing difficulty and poor in distribution effect. The Venturi type distributor and the conical type distributor have relatively good distribution effects, but are difficult to process and high in production cost.

SUMMERY OF THE UTILITY MODEL

In view of the above, a distributor and an air conditioning apparatus are needed to solve the problem that the existing distributor is difficult to satisfy the requirements of better distribution effect and lower processing difficulty.

The utility model provides a distributor, this distributor are used for distributing the fluid medium of the double-phase mixture of gas-liquid, and the distributor is equipped with the cavity, and the cavity is equipped with the vortex structure, and the vortex structure is along the radial protrusion in the inner wall of cavity to change the mobile state of fluid medium in the cavity.

In an embodiment of the present invention, the distributor includes a flow inlet pipe and a distribution main body, and the flow inlet pipe is installed in the distribution main body. The cavity comprises an inflow channel arranged on the inflow pipe and a distribution cavity arranged on the distribution main body, the inflow channel is communicated with the distribution cavity, and the turbulent flow structure is arranged along the radial direction of the inflow channel and/or the distribution cavity in a protruding mode. Therefore, when the turbulent flow structure is arranged in the distributor, the turbulent flow structure can be arranged in the inflow channel of the inflow pipe or in the distribution cavity of the distribution main body, and then the inflow pipe and the distribution main body are assembled together. Thereby greatly reduced the setting degree of difficulty of vortex structure, also reduced the processing degree of difficulty of distributor.

In this way, the fluid medium, when leaving the inlet channel and entering the distribution chamber, passes the baffle hole. The cross-sectional area of the turbulent flow hole is smaller than that of the inflow channel, namely, part of the structure of the turbulent flow gasket can play a certain role in blocking the fluid medium. Under the blocking of the turbulence spacer, the fluid medium impacting the turbulence spacer can generate turbulence vortex in the inflow channel, so that the fluid medium is further mixed. And, the spoiler gasket is simple in structure and easy to assemble with the distributor.

In an embodiment of the present invention, a plurality of sawtooth portions are disposed on the hole wall of the turbulent flow hole and circumferentially distributed along the turbulent flow hole, and each sawtooth portion radially protrudes from the hole wall of the turbulent flow hole along the turbulent flow hole. After the fluid medium impacts the end surface of each serration close to the inflow channel, a corresponding turbulent vortex is generated in the inflow channel. That is, the plurality of serrations will cause the fluid medium to generate a plurality of turbulent eddies within the inlet channel. The multiple turbulent eddies provide more uniform mixing of the fluid medium.

In an embodiment of the present invention, the turbulence spacer has a fixing section extending along the axis of the inlet pipe, and the fixing section is fixedly connected to the distribution body or the inlet pipe.

The fluid medium is caused to continuously impact the inner wall of the throat section, and the throat section gives the fluid medium an opposite acting force, and the direction of the opposite acting force is in an axisymmetric relationship with the direction of the acting force given to the throat section by the fluid medium. Under the push of the reverse acting force, the fluid medium can move towards the direction which is axially symmetrical to the original moving direction after impacting the necking section. At this time, the fluid medium forms a turbulent vortex in the inflow passage. The turbulent vortex can further enhance the mixing effect of the gas-liquid two-phase fluid medium, so that the fluid medium is mixed more uniformly.

In an embodiment of the present invention, the necking edge of the necking section is a saw-toothed shape. The necking segment having the serrated edge causes a plurality of less turbulent eddies to be generated in the fluid medium impacting the necking segment, enhancing the mixing effect of the fluid medium.
