[0003] But in actual use, such as Figure 1 As shown, since the inlet on the main body faces the upward atomizing end face, the liquid easily impacts the atomizing end face directly after entering, causing a rebound phenomenon. This not only causes the refrigerant entering each branch to be easily uneven due to the flow rate, resulting in different liquid supply amounts to each branch of the multiplier, thereby affecting the evaporation and heat exchange performance of the evaporator, as well as the energy efficiency ratio of the entire refrigeration system.

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 As shown, in this solution, an air conditioning distributor on an air conditioner is mainly described in detail, but the air conditioning distributor is not limited to being used in air conditioners, but can also be applied to other places where distributors are used.

[0027] like Figures 1 to 4 As shown, an air conditioning distributor comprises: a main body 1, provided with an inlet 10 and a plurality of outlets 11, the inlet 10 and the outlets 11 are respectively arranged on both sides of the main body 1; an atomizing end face 2, located in the main body 1, the atomizing end face 2 is arranged along the axis of the inlet 10, and is located between the inlet 10 and the outlet 11, wherein the plurality of outlets 11 are all opened on the atomizing end face 2; a guide cone 3, arranged at the center position of the atomizing end face 2, a plurality of concave arc surfaces 30 are formed on the guide cone 3, the concave arc surfaces 30 are arranged one by one with the outlets 11, and the bottoms of the concave arc surfaces 30 are distributed at the periphery of the outlets 11, so as to ensure the uniformity of liquid supply to each outlet 11.

[0028] In the conventional distributor structure, since most of the refrigerant is rebounded by the atomizing end surface 2 after entering from the inlet 10, in this embodiment, a guide cone 3 is provided at the middle position of the atomizing end surface 2, such as Figure 2 and Figure 3 As shown, the guide cone 3 is located opposite to the inlet 10, and a plurality of concave arc surfaces 30 formed on the guide cone 3 are used to guide the liquid entering from the inlet 10 to the outlet 11 evenly by means of the concave arc surfaces 30. In other words, the guide cone 3 cooperates with the concave arc surfaces 30 to ensure the uniformity of liquid supply to each branch, and the air conditioning distributor has a simple overall structure, is easy to process, and has a low cost.

[0029] Preferably, in the guide cone 3, except for the concave arc surface 30, other structures thereof are also generally arranged in an arc shape, such as Figure 3 As shown, the difference is that the bottom of the structure is connected to the atomizing end face 2, so that the liquid entering from the inlet 10 can also contact the surface of the guide cone 3 in advance, play a certain buffering role, and then be guided to the atomizing end face 2 to achieve the desired atomization effect.

[0030] A circular arc convex block 31 is also formed at the top of the guide cone 3 , and the tops of the plurality of concave arc-shaped surfaces 30 are all connected to the circular arc convex block 31 .

[0031] Continue to refer Figure 2 and Figure 3 The arc convex block 31 is hemispherically arranged at the top of the guide cone 3 as a whole. Since the top of the concave arc surface 30 is connected to the arc convex block 31, the liquid entering from the inlet 10 can be evenly distributed to each concave arc surface 30 by the hemispherical arc convex block 31, further improving the uniformity of the liquid flowing from each concave arc surface 30 to the outlet 11.

[0032] A drainage portion 12 is also formed in the main body 1 . The drainage portion 12 is arranged in a bell-mouth shape, and a small end opening of the drainage portion 12 is connected to the inlet 10 , and a large end opening faces the atomization end surface 2 .

[0033] like Figure 2 and Figure 3 As shown, when the refrigerant enters the main body 1 from the inlet 10, the large end opening of the drainage portion 12 faces the atomizing end face 2, thereby being able to guide the refrigerant, so that after the refrigerant enters from the inlet 10, it can diffuse to the surroundings and cooperate with the atomizing end face 2 to further improve the atomization effect of the refrigerant, while reducing the impact and ensuring the quality of the refrigerant.

[0034] Further, if Figure 2 As shown, the present solution also includes: an atomizing chamber 13, wherein the atomizing chamber 13 is formed between the drainage portion 12 and the atomizing end face 2. The opening of the atomizing chamber 13 provides a place for the refrigerant to be atomized, thereby preventing the refrigerant from rebounding under the action of the atomizing end face 2 and affecting the flow rate of the refrigerant in the inlet 10.

[0035] The outlet 11 includes a first outflow channel 110 and a second outflow channel 111. The first outflow channel 110 is connected to the atomization chamber 13; one end of the second outflow channel 111 is connected to the first outflow channel 110, and the other end is connected to the outer surface of the main body 1, and the inner diameter of the second outflow channel 111 is greater than the inner diameter of the first outflow channel 110.

[0036] In this embodiment, by setting the outlet 11 as a first outflow channel 110 and a second outflow channel 111, on the one hand, it is convenient for the refrigerant to enter the subsequent air-conditioning copper tube, and on the other hand, one end of the subsequent air-conditioning copper tube can be inserted into the inner wall of the second outflow channel 111, thereby facilitating the welding of the subsequent air-conditioning copper tube.

[0037] Preferably, if Figure 3 and Figure 4As shown, the inlet 10 in this solution is located at the periphery of the guide cone 3 along the orthographic projection in the direction perpendicular to the atomizing end face 2. That is to say, the refrigerant entering from the inlet 10 can quickly reach the position of the guide cone 3 along a straight line, and the concave arc surface 30 on the guide cone 3 evenly distributes the liquid to the corresponding outlet 11, which ensures the uniformity of the liquid supply of the structure and improves the efficiency during operation.

[0038] Preferably, the main body 1 and the guide cone 3 in the present embodiment are cold-forging structures and are both made of copper. Although copper is more expensive than brass, the processing cost of brass is higher (material cutting loss is larger), and copper has better ductility. Therefore, by cold-forging the blank, the processing is convenient and the material loss is small, thus saving material cost and processing cost.

[0039] The axis center line of the inlet 10 is arranged parallel to the axis center line of the outlet 11 .

[0040] In this embodiment, the axial lines of the outlet 11 and the inlet 10 are arranged in parallel, so that after the refrigerant is redirected by the drainage portion 12 and the guide cone 3, it has the same deflection angle as the outlet 11, so that when the refrigerant enters the subsequent air-conditioning copper tube connected to the second outflow channel 111, it can collide with the inner wall of the subsequent air-conditioning copper tube, thereby increasing the atomization effect and ensuring the subsequent refrigeration effect.

[0041] It should be noted that the concave arc surface 30 on the guide cone 3 in the present embodiment can be adaptively adjusted according to the number of outlets 11 in the distributor. The present embodiment provides a specific distribution structure of the concave arc surface 30 on the guide cone 3 in the cases of two outlets 11 and three outlets 11. Of course, the number of the concave arc surface 30 on the guide cone 3 is not limited to the two cases in the present embodiment, but should also include other structural design methods.

[0042] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] In addition, in the present invention, the descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
