Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of air conditioner accessories, specifically relates to an air conditioner distributor. BACKGROUND

[0002] The air conditioner distributor is also called a liquid distributor, is generally located at the refrigerant inlet of the evaporator of the air conditioner indoor unit and is connected with the evaporator, and the function is to uniformly distribute the refrigerant after throttling and pressure reduction to each branch pipe of the evaporator to ensure that each part of the evaporator can effectively exchange heat.

[0003] The structure of the conventional air conditioner distributor is disclosed in the patent CN202311115672.2, which comprises an integrated structure of an inlet pipe and an outlet pipe, both of which are circular pipe structures, the outlet pipe is formed by a plurality of outlet holes distributed in the cylinder to form the outlet pipe, the refrigerant enters the inlet pipe and then uniformly flows out from the plurality of outlet holes, the outlet pipe is a copper pipe, the outlet pipe and the branch pipe of the evaporator need to be connected by welding, and each outlet hole needs to be connected with a branch pipe, but the outlet holes are distributed in the cylinder, and the part to be heated when welding each outlet hole is the part of the end surface of the entire cylindrical outlet pipe, since the thickness of the cylinder edge with the outlet hole is large, the welding difficulty is greatly improved, and the metal heating and melting is slow, which greatly reduces the welding efficiency and is not conducive to the connection of the air conditioner distributor and the evaporator. SUMMARY

[0004] To solve the above problems, the utility model provides an air conditioner distributor, which comprises an inlet section and an outlet section, the inlet section is provided with an inlet hole, the outlet section is provided with at least two outlet holes, the outlet holes and the inlet hole are communicated, the outlet holes are provided with hole walls, and the hole walls corresponding to each outlet hole are respectively provided with a hole wall contact part and a hole wall independent part.

[0005] The hole wall contact part is arranged in the mutual approaching direction between the outlet holes, and the hole wall independent part is arranged in the mutual moving away direction between the outlet holes, so that a groove is formed between the adjacent hole walls.

[0006] Further, a transition section is arranged at the connection between the outlet section and the inlet section, and the projection area of the transition section along the liquid flow direction is greater than the projection area of the outlet section along the liquid flow direction.

[0007] The air conditioner distributor is produced by cold heading forming, so the inlet section, the outlet section and the transition section are integrally formed.

[0008] Further, the transition section has a reinforcing part at the position corresponding to the groove, and the reinforcing part is integrally connected with the outlet section.

[0009] The transition section increases the thickness of the connection between the hole wall and the liquid inlet section, thereby improving the overall compression strength. At the same time, the transition section also reduces the difficulty of processing, as the groove does not need to be completely punched through the liquid outlet section.

[0010] Further, the length of the transition section accounts for 1 / 7 to 1 / 4 of the length of the liquid outlet section in the direction of the medium flow from the liquid inlet section to the liquid outlet section.

[0011] The thickness of the transition section should not be too large, as a large thickness will increase the consumption of materials and the production cost. On the other hand, the thickness of the transition section should not be too small, as a small thickness will not increase the compression strength.

[0012] Further, the contact part of the adjacent two hole walls is integrated, the thickness of the hole wall independent part is the same as the minimum thickness of the corresponding hole wall contact part. That is, the two adjacent liquid outlet holes share a hole wall contact part, and the thickness of the hole wall independent part of the two liquid outlet holes is the same as or approximately the same as the thickness of the hole wall contact part.

[0013] This arrangement can make the distance between the liquid outlet holes more compact, which is beneficial to reducing the volume of the liquid outlet section and thereby saving the occupied space. In addition, this arrangement can make the thickness of the entire hole wall more uniform, improve the stress balance, and also save the consumption of materials to some extent and reduce the weight of the distributor. At the same time, the same thickness can make the heat conduction at each place approximately the same during welding, which is beneficial to strengthening the welding effect. However, the reduced space may bring some difficulties to the welding operation.

[0014] Further, the sum of the lengths of the liquid outlet section and the transition section in the direction of the liquid flow accounts for 1 / 3 to 1 / 2 of the length of the liquid inlet section in the direction of the liquid flow.

[0015] Since the material consumption of the liquid outlet section and the transition section accounts for a larger proportion than the liquid inlet section, the liquid outlet section should not be too long, as a long liquid outlet section will increase the production cost.

[0016] Further, in the direction of the hole wall circumference, the length of the hole wall independent part is not less than 1 / 4 of the hole wall circumference.

[0017] When the proportion of the hole wall independent part to the entire hole wall is greater than 1 / 4, the groove will appear, and the proportion of the hole wall independent part will continue to increase. Compared with the original structure, the material consumption will continue to decrease, and the groove will continue to increase, making the pipe wall thinner than the original structure. When the hole wall independent part accounts for half of the hole wall, the weight reduction reaches 15% to 17%.

[0018] Further, the liquid inlet section and the hole wall are designed as circular tubes, and the liquid inlet section and the liquid outlet section are integrally formed.

[0019] Further, a positioning hole is arranged at the center of the end face of the liquid outlet section, and the liquid outlet holes are arranged in a circular array relative to the positioning hole.

[0020] The positioning hole is arranged to ensure that the position of each liquid outlet hole is not deviated during the molding, and to ensure that the specifications of each air conditioner distributor are the same during production.

[0021] Further, the transition section is in a circular tube structure, the outermost ends of all the hole wall independent parts are connected into a circle, the radius of the circle is equal to the radius of the transition section, that is, the projection of the outermost ends of the hole wall along the liquid flow direction coincides with the projection of the transition section along the liquid flow direction, and the radius of the transition section does not need to be too large, and too large radius increases the material consumption and makes the processing more difficult.

[0022] The air conditioner distributor has the advantages that:

[0023] (1) The air conditioner distributor reduces the pipe wall thickness, makes the heating speed faster and more balanced during welding, solves the problems in the background art, and improves the welding speed.

[0024] (2) The air conditioner distributor reduces the material consumption, and compared with the original structure, the material consumption is reduced by 15% to 17% under the same specification, and the production cost is saved.

[0025] (3) The air conditioner distributor reduces the weight of the air conditioner distributor, and compared with the original structure, the air conditioner distributor is lighter in quality and occupies less space, and the installation and transportation pressure is reduced.

In the description of the present application, the description of the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0036] As Figs. 1-3 As shown in the figure, an air conditioner distributor includes a liquid inlet section 1 and a liquid outlet section 2, the liquid inlet section 1 is provided with a liquid inlet hole 11, the liquid outlet section 2 is provided with four liquid outlet holes 21, the liquid outlet hole 21 and the liquid inlet hole 11 are communicated, the liquid outlet hole 21 is provided with a hole wall 22, and the hole wall 22 corresponding to each liquid outlet hole 21 is respectively provided with a hole wall contact part 222 and a hole wall independent part 221.

[0037] The hole wall contact part 222 is arranged corresponding to the mutual approaching direction between the liquid outlet holes 21; the hole wall independent part 221 is arranged corresponding to the mutual moving away direction between the liquid outlet holes 21, so that the grooves 23 are formed between the adjacent hole walls 22.

[0038] In one specific embodiment, a transition section 3 is arranged at the connection between the liquid outlet section 2 and the liquid inlet section 1, and the projection area of the transition section 3 along the liquid flow direction is greater than the projection area of the liquid outlet section 2 along the liquid flow direction.

[0039] The air conditioner distributor is produced by cold heading forming, so the liquid inlet section 1, the liquid outlet section 2 and the transition section 3 are integrally formed.

[0040] In one specific embodiment, the transition section 3 has a reinforcing part 31 corresponding to the position of the groove 23, and the reinforcing part 31 is integrally connected with the liquid outlet section 2.

[0041] The arrangement of the transition section 3 increases the thickness of the connection between the hole wall 22 and the liquid inlet section 1, thereby improving the overall compressive strength. At the same time, the arrangement of the transition section 3 also makes it unnecessary to completely punch the groove 23 through the liquid outlet section 2 during processing, thereby reducing the processing difficulty.

[0042] In one specific embodiment, the thickness of the transition section 3 along the medium flow direction from the liquid inlet section 1 to the liquid outlet section 2 is 1 / 7 to 1 / 4 of the thickness of the liquid outlet section 2.

[0043] The thickness of the transition section 3 should not be too large, otherwise the material consumption will be increased and the production cost will be increased. The thickness of the transition section 3 should also not be too small, otherwise the effect of increasing the compressive strength will not be achieved.

[0044] In one specific embodiment, the two adjacent hole wall contact parts 222 are integrated, the wall thickness of the hole wall independent part 221 is the same as the minimum wall thickness of the corresponding hole wall contact part 222; that is, the two adjacent liquid outlet holes 21 share one hole wall contact part 222, and the thicknesses of the hole wall independent parts 221 of the two liquid outlet holes 21 are the same as or approximately the same as the thickness of the hole wall contact part 222.

[0045] This arrangement can make the distance between the liquid outlet holes 21 more compact, which is beneficial to reducing the volume of the liquid outlet section 2 and thereby saving the occupied space. This arrangement can also make the thickness of the entire hole wall 22 more uniform, improve the stress balance, and to some extent save material consumption and reduce the weight of the distributor. At the same time, the same wall thickness can make the heat conduction at each place approximately the same during welding, which is beneficial to strengthening the welding effect, but the space reduction will bring some difficulties to the welding operation.

[0046] In one specific embodiment, the sum of the lengths of the liquid outlet section 2 and the transition section 3 along the liquid flow direction is 1 / 3 to 1 / 2 of the length of the liquid inlet section 1 along the liquid flow direction.

[0047] Because the material proportion of the liquid outlet section 2 and the transition section 3 is much larger than that of the liquid inlet section 1, the liquid outlet section 2 should not be too long, otherwise the production cost will be increased.

[0048] In one embodiment, the length of the hole wall independent part 221 is not less than 1 / 4 of the circumference of the hole wall 22.

[0049] When the proportion of the hole wall independent part 221 in the whole hole wall 22 is greater than 1 / 4, the groove 23 will appear, and the proportion of the hole wall independent part 221 will continue to increase, and the material will continue to decrease compared with the original structure, and the groove 23 will continue to increase, so that the pipe wall is thinner than the original structure; when the hole wall independent part 221 accounts for half of the hole wall 22, the weight reduction reaches 15% to 17%.

[0050] In one embodiment, the liquid inlet section 1 and the hole wall 22 are designed as circular pipes, and the liquid inlet section 1 and the liquid outlet section 2 are integrally formed.

[0051] In one embodiment, the end surface of the liquid outlet section 2 is provided with a positioning hole 4, and the liquid outlet holes 21 are arranged in a circular array relative to the positioning hole 4.

[0052] The positioning hole 4 ensures that the positions of the liquid outlet holes 21 will not be deviated during processing and forming, and ensures that the specifications of each air conditioner distributor are the same during production, and the positioning hole 4 plays a positioning role to make the processing more convenient.

[0053] In one embodiment, the transition section 3 is a circular pipe structure, and the outermost ends of all the hole wall independent parts 221 are connected to form a circle, and the radius of the circle is equal to the radius of the transition section 3; that is, the projection of the outermost end of the hole wall 22 along the liquid flow direction coincides with the projection of the transition section 3 along the liquid flow direction; the radius of the transition section 3 does not need to be too large, and a too large radius will increase the consumption of materials and make the processing more difficult.

[0054] The parts not described in the utility model can be realized by using or referring to the existing technology.

[0055] Each embodiment in the specification is described in a progressive manner, and the same and similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the differences from other embodiments.

[0056] The above is only an embodiment of the utility model, and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the claim range of the utility model.
