Description

Technical Field

[0001] The utility model relates to the field of heat exchange systems, in particular to a distributor. Background Art

[0002] The existing distribution plate used in the heat exchange system generally adopts a folded plate or a flat plate, a number of small circular holes are evenly opened on the plate as outlets, and the plate is directly welded to the cylinder.

[0003] Among them, if the cylinder is too small, the above-mentioned distribution plate often cannot be fully welded to the cylinder, and because there are usually more point welding, there is no seal at the front and back ends, resulting in part of the liquid being unable to flow out evenly through the holes on the distribution plate, but flowing out more from the two ends and less from the middle, resulting in uneven distribution effect of the distribution plate.

[0004] In addition, since the small circular holes on the distribution plate are generally evenly distributed, when the inlet flow rate is too fast, they will often directly rush out of the distribution plate, resulting in more liquid outflow near the inlet and less liquid outflow far from the inlet, which will also make the distribution effect of the distribution plate uneven. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a distributor, which solves the problem that liquid easily flows out from both ends and welds through sealed welding between the top plate, end plate and bottom plate. At the same time, no holes are distributed within a certain range directly above the inlet, which solves the problem that the inlet flow rate is too fast and directly rushes out of the distribution plate, resulting in uneven distribution.

[0006] According to one aspect of the utility model, a distributor is provided, comprising a top plate, two vertical end plates and a horizontal bottom plate, wherein the top plate is located above the bottom plate, the two end plates are respectively located at the two ends of the bottom plate, and the top plate, the two end plates and the bottom plate are all sealed and welded; wherein a plurality of liquid outlet holes are arranged on the top plate, a liquid inlet is arranged at the bottom of the bottom plate, and a non-porous area on the top plate where the liquid outlet holes are not arranged is provided near the liquid inlet.

[0007] In some embodiments, the top plate is made of a metal sheet and is bent. The invention is beneficial in that the material and shape of the top plate are described.

[0008] In some embodiments, the liquid outlet hole is circular, square or triangular. The benefit of this is that it describes the size range of the liquid outlet hole.

[0009] In some embodiments, the diameter of the liquid outlet hole when it is circular is 3-8 mm, and the equivalent diameter of the liquid outlet hole when it is square or triangular is 3-8 mm. The benefit lies in that the optional shapes of the liquid outlet hole are described.

[0010] In some embodiments, the diameter of the liquid inlet is 35-80 mm. This is beneficial in that it describes the size range of the liquid inlet, preferably 54 mm.

[0011] In some embodiments, the sum of the cross-sectional areas of the liquid outlets is greater than 1.2 times the cross-sectional area of ​​the liquid inlet. This is beneficial in that it can ensure that the dispenser can dispense in a timely manner without liquid accumulation.

[0012] In some embodiments, the length of the non-porous region is twice the diameter of the liquid inlet. It is beneficial that the length design of the non-porous region is described.

[0013] In some embodiments, the bottom of the liquid inlet has a liquid inlet connecting pipe. The benefit lies in that the liquid inlet connecting pipe is used to connect the liquid inlet pipe, and can pass the liquid from the liquid inlet into the distributor. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-3 As shown, the distributor mainly includes a top plate 1, two vertical end plates 2 and a horizontal bottom plate 3. The top plate 1 is located above the bottom plate 3, the two end plates 2 are located at both ends of the bottom plate 3, and the top plate 1, the two end plates 2 and the bottom plate 3 are sealed and welded to form the main body of the distributor.

[0020] Preferably, the top plate 1 is made of a metal sheet and is bent, and the bending angle is preferably 120°.

[0021] A plurality of liquid outlet holes 4 are arranged on the top plate 1, and a liquid inlet 5 is arranged at the bottom of the bottom plate 3. The bottom of the liquid inlet 5 is connected with a liquid inlet connecting pipe 7, and the liquid inlet connecting pipe 7 is used to connect the liquid inlet pipe. Thus, the liquid can be introduced into the distributor from the liquid inlet 5 through the liquid inlet pipe, and then discharged through the liquid outlet holes 4 on the top plate 1, thereby achieving the distribution effect of the distributor.

[0022] In addition, near the liquid inlet 5, there is a non-porous area 6 on the top plate 1, and no liquid outlet hole 4 is arranged in the non-porous area 6. Thus, it can be prevented that the liquid introduced into the distributor from the liquid inlet 5 will directly flow out of the distributor without being distributed.

[0023] Preferably, the liquid outlet hole 4 on the top plate 1 is circular, square or triangular, wherein the diameter of the liquid outlet hole 4 when circular is 3-8 mm, and the equivalent diameter of the liquid outlet hole 4 when square or triangular is 3-8 mm.

[0024] Preferably, the diameter of the liquid inlet 5 is 35-80 mm, more preferably 54 mm, and the length of the non-porous area 6 is preferably twice the diameter of the liquid inlet 5, that is, 108 mm.

[0025] In addition, the sum of the cross-sectional areas of the liquid outlet holes 4 is greater than 1.2 times the cross-sectional area of ​​the liquid inlet 5, which can ensure that the distributor can distribute in time without liquid accumulation.

[0026] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
