Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a distributor with uniform and stable liquid separation. Background Art

[0002] The distributor is one of the commonly used components in the field of refrigeration technology. It is usually installed at the inlet of the heat exchanger and can evenly distribute the gas-liquid two-phase liquid medium to each pipeline of the heat exchanger. The gas-liquid two-phase liquid medium entering the distributor often flows in layers. If the medium entering the distributor is directly distributed to each pipeline, it is easy to cause uneven liquid distribution. Most traditional air conditioner distributors directly distribute the medium entering the distributor to each pipeline, and the liquid distribution uniformity and stability are poor. Although there are also ways to change the angles of the distributor inlet and outlet in the prior art, the actual effect improvement is not obvious enough. Although there are also solutions to install capillaries or branch pipes on the distributor outlet, the structural stability between the installed pipes and the distributor is not well guaranteed. Therefore, it is necessary to make structural improvements to overcome the above defects. Summary of the invention

[0003] In view of this, the invention aims to overcome the defects in the prior art and proposes a dispenser with uniform and stable liquid separation.

[0022] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] A dispenser with uniform and stable liquid separation, such as Figures 1 to 4 As shown, the distributor body 1 includes an inlet pipe 2 at the rear shell end of the distributor body, a plurality of outlet pipes 3 at the front shell end, and a limiting frame 6 is installed inside the rear shell 4 or inside the front shell 5. Usually, there are 2 to 8 outlet pipes. A distribution chamber 7 is formed inside the distributor body at the limiting frame on the side of the rear shell, and a mixing chamber 8 is formed at the side of the limiting frame on the front shell. The limiting frame is used to effectively limit the inlet pipe and the outlet pipe in the radial direction of the distributor, thereby improving the stability of the inlet and outlet pipes.

[0025] The limiting frame is provided with an inlet pipe limiting ring 9 that matches the inlet pipe, and an outlet pipe limiting ring 10 that matches each outlet pipe one by one. At the same time, a filter screen 11 is installed on the limiting frame, and the filter screen covers other parts except the limiting rings. The inlet pipe passes through the inlet pipe limiting ring and extends to the mixing chamber. The outlet pipe extends into one end of the inner cavity of the distributor body, passes through the outlet pipe limiting ring and extends to the distribution chamber; a sheath tube 12 is provided on the panel of the front shell corresponding to each outlet pipe, and the outlet pipe is inserted into the sheath tube and fixed. Usually, the sheath tube includes an inner extension section 16 extending into the distributor body, and an outer extension section 17 extending out of the distributor body. The sheath tube effectively increases the joint area between the outlet pipe and the distributor, avoids stress concentration of the outlet pipe at the end plate, and the outlet pipe is not prone to deformation such as bending due to force, and has good structural stability.

[0026] In an optional embodiment, if Figure 4 As shown, a diverter component 21 is provided on the inner side of the front shell panel at the position corresponding to the inlet pipe. The diverter component is conical in shape, with its conical end pointing to the center of the inlet pipe. A liquid gap is left between the end of the inlet pipe and the surface of the diverter component. When the distributor is working, the medium enters the distributor body through the inlet pipe, and is diverted to various directions through the diverter component at the end of the corresponding inlet pipe, and is dispersed into the mixing chamber. After entering the mixing chamber, the medium changes its movement direction, and then enters the distribution chamber through the limit frame (filter screen). When the medium enters the outlet pipe from the distribution chamber, the movement direction changes here, and the end of the outlet pipe protrudes from the limit frame (filter screen), which further improves the uniformity of the refrigerant medium. In addition, each outlet pipe is evenly distributed with the axis of the distributor body as the center, which can effectively ensure uniform and stable liquid separation.

[0027] It should be noted that after the refrigerant medium enters the mixing chamber, it needs to turn before entering the distribution chamber, that is, the medium moves toward the limit frame side and is filtered by the filter screen at the limit frame to reduce impurities in the medium. At the same time, the filter screen will also form a mixing effect on the refrigerant medium to avoid stratified flow and improve the uniformity of liquid separation. In a further improved solution, a layer of filter screen can be installed on the surface of the diverter component, so that the diverter component can not only play a diversion role, but also allow impurities to adhere to the surface, which can play a filtering role to a certain extent, and the filter screen plays a role in dispersing the flow (direction) of the medium, thereby improving the uniformity of medium dispersion.

[0028] In order to facilitate assembly, disassembly, cleaning and maintenance, in an optional embodiment, the rear shell and the front shell of the dispenser body are detachably connected. The specific structure can be that the rear shell is provided with a rear flange 13 at one end facing the front shell, and the front shell is provided with a front flange 14 at one end facing the rear shell, and the front flange and the rear flange are connected by screws 15.

[0029] The above-mentioned limiting frame includes an outer fixing ring 18, and the outer fixing ring is connected to the inlet pipe limiting ring through a fixing rod 19. The outlet pipe limiting ring is installed on the fixing rod. The outlet pipe is inserted into the sheath pipe and the inner end of the outlet pipe is limited by the outlet pipe limiting ring. In addition, the outlet pipe and the sheath pipe are effectively fixed, which can effectively ensure the structural stability of each outlet pipe. The inlet pipe is inserted into the opening of the rear shell and the inner end of the inlet pipe is limited by the inlet pipe limiting ring. In addition, the inlet pipe and the rear shell are effectively fixed, which can effectively ensure the structural stability of the inlet pipe. In order to further improve the stability of the inlet pipe, in an optional embodiment, the opening end of the above-mentioned rear shell is provided with a limiting platform 20, and the outer wall of the inlet pipe is provided with a boss structure matched with the limiting platform.

[0030] The invention forms a limit on the inlet pipe and the outlet pipe through the limit frame, which effectively improves the structural stability of the inlet and outlet pipes, and the filter on the limit frame can effectively filter the medium to avoid clogging of the outlet pipe. After the refrigerant medium enters the distributor body, it undergoes multiple reversals and diversions, and the liquid separation is uniform and stable, with good use effect.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
