Description

Technical Field

[0001] This invention relates to the field of air conditioning system accessories technology, and more specifically, to a distributor and a heat exchanger having the same. Background Technology

[0002] Distributors are typically installed at the inlet of air conditioning heat exchangers to distribute the two-phase flow medium evenly to each flow path of the heat exchanger.

[0003] The biggest technical challenge of the distributor is how to distribute the gas-liquid two-phase fluid at the inlet evenly after thorough mixing. The two-phase flow at the inlet of the distributor often exhibits stratified flow. If distribution is carried out directly, it is easy to cause uneven distribution due to gravity.

[0004] In related technologies, there are generally three types of distributors commonly used in household / commercial air conditioners: socket type, venturi type, and conical socket type. Among them, the socket type has a simple structure and is easy to manufacture, but its distribution effect is poor; the venturi type and conical type have relatively better distribution effects, but they are more difficult to manufacture and have higher costs. Summary of the Invention

[0005] The main objective of this invention is to provide a distributor and a heat exchanger having the same, so as to solve the problem that the distributor in the prior art cannot simultaneously achieve good distribution effect and low processing difficulty.

[0006] To achieve the above objectives, according to one aspect of the present invention, a dispenser is provided, comprising: an injection tube including a first end and a second end, the second end having a first nozzle; a reflector having a first receiving cavity, the reflector being sleeved on the second end, the first nozzle being located within the first receiving cavity, the reflector having a second nozzle, the first nozzle and the second nozzle being offset from each other.

[0007] Furthermore, the dispenser also includes a dispensing body having a second receiving cavity, a reflector located within the second receiving cavity, and a second nozzle disposed opposite to the inner wall surface of the dispensing body.

[0008] Furthermore, the distribution body is also provided with a distribution hole, which is offset from the second nozzle.

[0009] Furthermore, the dispensing body includes a bottom wall and a circumferential side wall connected to the bottom wall, a dispensing hole is disposed on the bottom wall, and the second nozzle is offset from the dispensing hole.

[0010] Furthermore, there are multiple first nozzles, which are spaced apart in the axial and / or circumferential directions of the injection pipe; and there are multiple second nozzles, which are spaced apart on the sidewall of the reflector.

[0011] Furthermore, there are multiple distribution holes, which are spaced apart on the bottom wall of the distribution body.

[0012] Furthermore, the reflector is welded to the injection tube.

[0013] Furthermore, the dispensing body and the injection tube are welded together.

[0014] Furthermore, the circumferential sidewall includes: a small-diameter section connected to the injection pipe; and a large-diameter section fitted around the outer periphery of the reflector.

[0015] The connecting section connects the small-diameter section and the large-diameter section; the second nozzle is positioned opposite the large-diameter section.

[0016] According to another aspect of the present invention, a heat exchanger is provided, including a piping structure and a distributor disposed on the piping structure, wherein the distributor is the distributor described above.

[0017] By applying the technical solution of the present invention, since a reflector is provided and the second nozzle on the reflector is misaligned with the first nozzle on the injection pipe, the medium ejected from the first nozzle collides with the reflector and is then ejected onto the outer wall of the injection pipe before being ejected through the second nozzle. This allows the liquid phase in the medium to be fully atomized and uniformly mixed with the gas phase in the medium, resulting in uniform medium distribution and improved distribution effect of the distributor. Furthermore, the distributor has a simple structure, is easy to manufacture, and has a low cost. Attached Figure Description

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a dispenser, including an injection tube 10 and a reflector 20. The injection tube 10 includes a first end and a second end, and the second end is provided with a first nozzle 11; the reflector 20 has a first receiving cavity, the reflector 20 is sleeved on the second end, the first nozzle 11 is located in the first receiving cavity, and the reflector 20 is provided with a second nozzle 21, the first nozzle 11 and the second nozzle 21 being offset.

[0030] In this embodiment, because a reflector 20 is provided, the second nozzle 21 on the reflector 20 is misaligned with the first nozzle 11 on the injection pipe 10. This causes the medium ejected from the first nozzle 11 to collide with the reflector 20 and be ejected onto the outer wall of the injection pipe 10 before being ejected through the second nozzle 21. This allows the liquid phase in the medium to be fully atomized and mixed evenly with the gas phase in the medium, resulting in uniform medium distribution and improved distribution effect of the distributor. Furthermore, the distributor has a simple structure, is easy to manufacture, and has a low cost.

[0031] Specifically, such as Figure 4 As shown, the reflector 20 is a tubular structure with an inner diameter larger than the outer diameter of the injection pipe 10, creating a gap between the inner wall of the reflector 20 and the outer wall of the injection pipe 10. This gap forms a reflection space for the medium jet. The medium ejected from the first nozzle 11 is sprayed onto the inner wall of the reflector 20. After colliding with the inner wall of the reflector 20, the medium is reflected to the outer wall of the injection pipe 10, then collides again with the outer wall of the injection pipe 10 and is reflected again before being ejected through the second nozzle 21. The liquid phase in the collided medium vaporizes, resulting in a more uniform medium distribution and a better distribution effect.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the dispenser further includes a dispensing body 30, which has a second receiving cavity, a reflector 20 located in the second receiving cavity, and a second nozzle 21 disposed opposite to the inner wall surface of the dispensing body 30.

[0033] With the above configuration, the medium ejected from the second nozzle 21 collides with the inner wall of the distributor 30 for the third time, thereby fully atomizing the remaining liquid phase in the medium and mixing it evenly with the gas phase. This further ensures that the medium becomes a gas phase and flows to each flow path of the heat exchanger, resulting in good distribution effect and simple structure of the distributor.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the dispensing body 30 is also provided with a dispensing hole 31, which is offset from the second nozzle 21.

[0035] After undergoing a third collision within the distribution body 30, the water flows through the distribution holes 31 to various flow paths of the heat exchanger, resulting in uniform distribution and ease of processing.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the dispensing body 30 includes a bottom wall and a circumferential side wall connected to the bottom wall, the dispensing hole 31 is disposed on the bottom wall, and the second nozzle 21 is offset from the dispensing hole 31.

[0037] Because the second nozzle 21 and the distribution hole 31 are misaligned, the medium sprayed from the second nozzle 21 will not flow directly to the distribution hole 31, but will first collide with the inner wall of the distribution body 30 to atomize before flowing out through the distribution hole 31, resulting in a high degree of atomization of the medium, uniform distribution of the medium, and good distribution effect of the distributor.

[0038] Preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, there are multiple first nozzles 11, which are spaced apart in the axial and circumferential directions of the injection pipe 10. There are also multiple second nozzles 21, which are spaced apart on the sidewall of the reflector 20.

[0039] The above configuration improves the distribution efficiency of the distributor, and the media ejected from multiple first nozzles 11 all collide with the reflector 20, and the media ejected from multiple second nozzles 21 can also collide with the distributor 30, thereby improving the atomization efficiency and ensuring the distribution effect of the media.

[0040] Preferably, there are multiple distribution holes 31, which are spaced apart on the bottom wall of the distribution body 30.

[0041] The above settings further improve the distributor's distribution efficiency, ensuring that the medium can flow evenly to different flow paths.

[0042] Preferably, the reflector 20 is welded to the injection tube 10.

[0043] The above configuration ensures a high connection strength between the reflector 20 and the injection tube 10, guarantees the sealing between the reflector 20 and the injection tube 10, and has a simple connection method with low cost.

[0044] Preferably, the dispensing body 30 is welded to the injection tube 10.

[0045] The above configuration ensures a high connection strength between the dispensing body 30 and the injection tube 10, guarantees the sealing between the dispensing body 30 and the injection tube 10, and has a simple connection method with low cost.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, the circumferential sidewall includes a small-diameter section 32, a large-diameter section 33, and a connecting section 34. The small-diameter section 32 is connected to the injection pipe 10; the large-diameter section 33 is sleeved on the outer periphery of the reflector 20; the connecting section 34 connects the small-diameter section 32 and the large-diameter section 33; wherein, the second nozzle 21 is disposed opposite to the large-diameter section 33.

[0047] Through the above settings, a gap is created between the large-diameter section 33 and the reflector 20, and the collision reflection of the medium is realized, so that the liquid phase in the medium is fully atomized into the gas phase, ensuring a good distribution effect.

[0048] Meanwhile, the small-diameter section 32 is connected to the injection pipe 10, which reduces the connection range and further reduces the welding difficulty and cost.

[0049] This embodiment also provides a heat exchanger, including a piping structure and a distributor disposed on the piping structure, wherein the distributor is the distributor described above.

[0050] In this embodiment, because a reflector 20 is provided, the second nozzle 21 on the reflector 20 is misaligned with the first nozzle 11 on the injection pipe 10. This causes the medium ejected from the first nozzle 11 to collide with the reflector 20 and be ejected onto the outer wall of the injection pipe 10 before being ejected through the second nozzle 21. This allows the liquid phase in the medium to be fully atomized and mixed evenly with the gas phase in the medium, resulting in uniform medium distribution and improved distribution effect of the distributor. Furthermore, the distributor has a simple structure, is easy to manufacture, and has a low cost.

[0051] Therefore, heat exchangers with upper distributors also have the aforementioned advantages.

[0052] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0053] Because of the reflector, the second nozzle on the reflector is misaligned with the first nozzle on the injection pipe. This causes the medium ejected from the first nozzle to collide with the reflector and be ejected onto the outer wall of the injection pipe before being ejected through the second nozzle. This allows the liquid phase in the medium to be fully atomized and mixed evenly with the gas phase, resulting in uniform medium distribution and improved distribution efficiency. Furthermore, the distributor has a simple structure, is easy to manufacture, and has a low cost.

[0054] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0055] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
