Description

Technical Field

[0001] The present application relates to the field of liquid separation technology, and in particular to a distributor and an air conditioning system. Background Art

[0002] The main function of the distributor in the air conditioning system is to fully mix the gas-liquid two-phase refrigerant and then supply liquid to each branch of the evaporator evenly and equally, so as to achieve the best cooling effect.

[0003] In the related art, the distributor has multiple outlets. Due to the space limitation of the distributor, the multiple outlets are generally arranged at intervals along the circumference and close to the outer edge of the distributor. When the outlet is welded to the outlet pipe, due to the use of flame welding, usually only the peripheral edge of the distributor can be heated. After the distributor is heated to a predetermined temperature, solder is applied for welding. However, this will cause the temperature of the peripheral edge of the distributor to be higher than the temperature at the center point (for the same end face) during welding. In addition, due to the heat tendency of solder, the solder is more likely to flow toward the edge of the distributor with a higher temperature after melting, resulting in outflow welding, which makes the outlet and the outlet pipe poorly welded, and the distributor after welding has a greater risk of leakage.

[0027] The main function of the distributor in the air conditioning system is to fully mix the gas-liquid two-phase refrigerant and then supply liquid to each branch of the evaporator evenly and equally, so as to achieve the best cooling effect.

[0028] In the related art, the distributor has multiple outlets. Due to the space limitation of the distributor, the multiple outlets are generally arranged at intervals along the circumference and close to the outer edge of the distributor. When the outlet is welded to the outlet pipe, due to the use of flame welding, usually only the peripheral edge of the distributor can be heated. After the distributor is heated to a predetermined temperature, solder is applied for welding. However, this will cause the temperature of the peripheral edge of the distributor to be higher than the temperature at the center point (for the same end face) during welding. In addition, due to the heat tendency of solder, the solder is more likely to flow toward the edge of the distributor with a higher temperature after melting, resulting in outflow welding, which makes the outlet and the outlet pipe poorly welded, and the distributor after welding has a greater risk of leakage.

[0029] See also Figure 1-Figure 3In order to solve the problem that outflow welding is easy to occur when welding the existing distributor and the outlet pipe, the present application provides a distributor 100. The distributor 100 includes a main body 10, and the main body 10 has an inlet 101 and an outlet 102. The inlet 101 and the outlet 102 are arranged at opposite ends of the main body 10 along the axial direction of the main body 10, and the number of outlets 102 is multiple, and the multiple outlets 102 are arranged at intervals along the circumference of the main body 10 and are arranged close to the outer edge of the main body 10. Among them, the end surface of the main body 10 provided with the outlet 102 is defined as a connecting surface 121, and along the axial direction of the main body 10 and in the direction from the outlet 102 to the inlet 101, the connecting surface 121 is gradually contracted from the outer edge to the center.

[0030] The present application sets the connection surface 121 provided with the outlet 102 on the main body 10 as a gradually shrinking concave structure. When the main body 10 of the dispenser 100 is fixed by welding the outlet 102 and the outlet pipe, the connection surface 121 can be set upward. At this time, the melted solder has a tendency to move toward the axial direction of the main body 10 under the action of gravity, which is opposite to the direction in which the solder flows toward the edge of the main body 10 due to its thermal tendency, thereby avoiding the outflow of solder, making the solder spread evenly at the soldering point, achieving stable penetration of the solder, and eliminating the leakage risk of the dispenser 100.

[0031] It should be noted that, as the temperature is higher, the surface tension of the molten metal is lower, and thus the fluidity is better, resulting in the solder's thermotropism, that is, the solder will flow in the direction of higher temperature.

[0032] In one embodiment, if Figure 2 As shown, the connection surface 121 is configured in a conical shape, so that the connection surface 121 has a simple structure and is easy to process, thereby improving the processing efficiency of the connection surface 121 .

[0033] Further, in one embodiment, if Figure 2 As shown, the cross-sectional taper angle A of the connection surface 121 satisfies 165°≤A≤170°. By properly setting the cross-sectional taper angle of the connection surface 121, the reliability of soldering can be greatly improved.

[0034] Specifically, when the cross-sectional cone angle A of the connection surface 121 is greater than 170°, the angle formed by the connection surface 121 and the horizontal plane is small, and the weight of the solder is insufficient to completely overcome its thermal tendency, which easily causes the solder to flow toward the edge of the distributor 100, thereby causing welding defects such as outflow soldering. When A is less than 165°, the angle formed by the connection surface 121 and the horizontal plane is large, and the weight of the solder causes the solder to flow toward the center of the connection surface 121 more easily, which also causes uneven distribution of solder at the solder joint, thereby reducing the welding effect between the distributor 100 and the outlet pipe.

[0035] Exemplarily, the cone angle A of the connecting surface 121 may be set to 165°, 166°, 167°, 168°, 169° or 170°, etc., which are not listed here one by one.

[0036] In other embodiments, the connection surface 121 may also be arc-shaped, etc. Of course, the connection surface 121 may also be set to be a plane at a position close to the axis, etc., as long as the same effect can be achieved.

[0037] In one embodiment, the number of outlets 102 is greater than or equal to 4. Due to the number of outlets 102, their arrangement often affects the distance between the outlet 102 and the edge of the main body 10 of the dispenser 100. When the number of outlets 102 is greater than or equal to 4, the distance between the outlet 102 and the edge of the main body 10 of the dispenser 100 is closer, usually only about 1.5 mm, which is more likely to cause the risk of outflow welding. However, the present application can effectively solve the outflow welding problem of the dispenser 100 with more outlets 102 by providing an inwardly concave connection surface 121, thereby meeting the welding use requirements of the dispenser 100 with multiple outlets 102.

[0038] Specifically, Figure 3 As shown, five outlets 102 are provided in this embodiment, and the five outlets 102 are evenly spaced along the circumference of the main body 10. However, it is not limited thereto, and in other embodiments, the number of the outlets 102 may be set to 4, 6, 7, 8 or more, which may be reasonably set according to actual needs.

[0039] To further improve the uniformity of solder during soldering of each outlet 102, in one embodiment, the axis of the connecting surface 121 can be coaxially arranged or nearly coaxially arranged with the axis of the main body 10. It should be noted that the coaxial arrangement here is not limited to coaxiality in an absolute sense, and can also include coaxial arrangements within a tolerance range.

[0040] In one embodiment, if Figure 2 As shown, the main body 10 is provided with a liquid inlet 103, a liquid separation cavity 105 and a liquid separation hole 106. One end of the liquid separation cavity 105 is connected to the inlet 101 through the liquid inlet 103, and the other end is connected to the outlet 102 through the liquid separation hole 106. In this way, the fluid can flow in and out of the distributor 100 and achieve uniform liquid separation.

[0041] Furthermore, a jet hole 104 is provided in the main body 10, and the two ends of the jet hole 104 are respectively connected to the liquid inlet hole 103 and the liquid separation cavity 105. The aperture of the jet hole 104 is smaller than the aperture of the liquid inlet hole 103. Thus, when the fluid flows through the jet hole 104, the fluid flow rate increases due to the decrease in the aperture, and the gas-liquid mixing is more uniform, which is conducive to improving the distribution effect of the distributor 100.

[0042] In one embodiment, the main body 10 is configured as an integrated structure, so that the structure of the main body 10 is relatively compact, and the matching between the various liquid separation holes 106 and the liquid separation chambers 105 is more accurate, thereby achieving a better liquid separation effect.

[0043] In another embodiment, if Figure 2 As shown, the main body 10 includes a liquid inlet 11 and a liquid outlet 12, the liquid outlet 12 is provided with an assembly groove 1201, one end of the liquid inlet 11 is inserted and installed in the assembly groove 1201, and the liquid inlet 11 and the liquid outlet 12 are surrounded to form a liquid separation cavity 105. Among them, the liquid inlet hole 103 is provided in the liquid inlet 11, and the liquid separation hole 106 is provided in the liquid outlet 12.

[0044] That is, by configuring the main body 10 as a separate liquid inlet portion 11 and a liquid outlet portion 12, it is convenient to process the liquid inlet hole 103, the liquid separation cavity 105 and the liquid separation hole 106 on the liquid inlet portion 11 and the liquid outlet portion 12 accordingly, which helps to reduce the processing difficulty.

[0045] Furthermore, in one embodiment, a diverter cone 13 is provided on the liquid outlet 12, the diverter cone 13 protrudes and is connected to the bottom wall of the assembly groove 1201, and the diverter cone 13 and the liquid inlet 11 are arranged to form a liquid diverting cavity 105. Among them, along the axial direction of the main body 10, and from the inlet 101 to the outlet 102, the diverter cone 13 has a tendency to gradually expand. The diverter cone 13 can divert the high-speed fluid entering the liquid diverting cavity 105, and the fluid can flow more smoothly along the surface of the diverter cone 13, which can not only reduce the flow loss of the fluid, but also enable the fluid to smoothly enter the subsequent distribution hole, thereby greatly improving the diversion effect of the distributor 100.

[0046] Specifically, the diverter cone 13 may be configured to be a cone or a triangular cone, etc. The diverter cone 13 is preferably configured to be an integrated structure with the liquid outlet 12 to improve the structural strength of the diverter cone 13 .

[0047] In one embodiment, the main body 10 is a brass member. Brass has good machinability and corrosion resistance and is easy to be welded with the outlet pipe.

[0048] The present application also provides an air conditioning system, which includes an outlet pipe and a distributor 100 of any one of the above embodiments, one end of the outlet pipe is inserted into the main body 10 through the outlet 102, and the outlet pipe is welded and fixed to the main body 10. The outlet pipe can achieve a stable welding effect with the main body 10 due to the concave setting of the connection surface 121 on the main body 10.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
