AI Technical Summary

Technical Problem

In existing heat exchange systems, the distribution plate cannot be fully welded when the cylinder is too small, resulting in poor sealing, uneven liquid distribution, and easy overflow when the inlet flow rate is too high, causing uneven distribution.

Method used

The system adopts a sealed welded structure consisting of a top plate, end plate, and bottom plate. The top plate is provided with an outlet hole and a hole-free area is provided at the inlet. The size and distribution of the outlet hole and inlet are designed to ensure uniform distribution.

Benefits of technology

It achieves uniform liquid distribution under high flow rate conditions, avoids liquid flowing out from both ends and the orifice, and improves the sealing performance and distribution uniformity of the distributor.

Abstract

Disclosed is a distributor. The distributor comprises a top plate (1), two vertical end plates (2) and a horizontal bottom plate (3), wherein the top plate (1) is located above the bottom plate (3), the two end plates (2) are respectively located at two ends of the bottom plate (3), and the top plate (1), the two end plates (2) and the bottom plate (3) are all sealingly welded; and a plurality of liquid outlet holes (4) are provided in the top plate (1), a liquid inlet (5) is provided at the bottom of the bottom plate (3), and there is a hole-less region (6) without the liquid outlet holes (4) on the top plate (1) close to the liquid inlet (5). The distributor in the present disclosure solves, by means of the sealed welding between the top plate, the end plates and the bottom plate, the problem of liquid easily flowing out via the two ends and welding seams, and solves, by means of providing no holes within a certain range over the inlet, the problem of uneven distribution caused by liquid at the inlet having an extremely high flow velocity and directly rushing out of a distribution plate.

Description

A distributor

[0001] This application claims priority to the following Chinese patent application: Chinese patent application No. 202421250766.0, filed on June 3, 2024, and entitled “A distributor”. The entire content of this patent application is incorporated herein by reference. TECHNICAL FIELD

[0002] The present disclosure relates to the field of heat exchange systems, and in particular to a distributor. BACKGROUND

[0003] The existing distributor used in heat exchange systems generally adopts a folded plate or a flat plate, a plurality of small round holes are evenly opened on the plate as outlets, and the plate is directly welded on the cylinder.

[0004] Among them, if the cylinder is too small, the above-mentioned distributor plate cannot be fully welded with the cylinder, and because there are usually more point segment welds, the front and rear ends are not sealed, so that part of the liquid cannot flow out uniformly through the holes on the distributor plate, but flows out more from the two ends and less from the middle, resulting in uneven distribution effect of the distributor plate.

[0005] In addition, because the small round holes on the distributor plate are generally evenly distributed, when the inlet flow rate is too fast, the liquid near the inlet will flow out more and the liquid far from the inlet will flow out relatively less, which also causes uneven distribution effect of the distributor plate. SUMMARY

[0006] To solve the above-mentioned problems, the present disclosure provides a distributor which solves the problem that liquid easily flows out from the two ends and the weld by sealing welding between the top plate, the end plate and the bottom plate, and solves the problem of uneven distribution caused by the liquid directly flowing out of the distributor plate when the inlet flow rate is too fast by not distributing holes within a certain range directly above the inlet.

[0007] According to one aspect of the present disclosure, a distributor is provided, comprising a top plate, two vertical end plates and a horizontal bottom plate, 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 sealingly welded; wherein the top plate is provided with a plurality of liquid outlet holes, the bottom of the bottom plate is provided with a liquid inlet, and the top plate has a hole-free area without the liquid outlet holes near the liquid inlet.

[0008] In some embodiments, the top plate is made of a metal sheet and has a bent shape. It is beneficial to describe the material and shape of the top plate.

[0009] In some embodiments, the liquid outlet hole is circular, square or triangular. It is beneficial in that the size range of the liquid outlet hole is described.

[0010] In some embodiments, the diameter of the liquid outlet hole is 3-8 mm when it is circular, and the equivalent diameter of the liquid outlet hole is 3-8 mm when it is square or triangular. It is beneficial in that the optional shape of the liquid outlet hole is described.

[0011] In some embodiments, the diameter of the liquid inlet is 35-80 mm. It is beneficial in that the size range of the liquid inlet is described, preferably 54 mm.

[0012] In some embodiments, the sum of the cross-sectional areas of the liquid outlet holes is greater than 1.2 times the cross-sectional area of the liquid inlet. It is beneficial in that it can ensure that the dispenser can be distributed in time, without liquid accumulation.

[0013] In some embodiments, the length of the non-hole area is twice the diameter of the liquid inlet. It is beneficial in that the length design of the non-hole area is described.

[0014] In some embodiments, the bottom of the liquid inlet has a liquid inlet connecting pipe. It is beneficial in that the liquid inlet connecting pipe is used to connect the liquid inlet pipe, which can pass the liquid from the liquid inlet into the dispenser. BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 1 is an exploded schematic view of a dispenser according to an embodiment of the present disclosure;

[0016] Figure 2 is a structural schematic view of the top plate shown in Figure 1;

[0017] Figure 3 is a structural schematic view of the bottom plate shown in Figure 1.

[0018] In the drawings: top plate 1, end plate 2, bottom plate 3, liquid outlet hole 4, liquid inlet 5, non-hole area 6, liquid inlet connecting pipe 7. DETAILED DESCRIPTION

[0019] The present disclosure will be further described in detail below with reference to the accompanying drawings.

[0020] As shown in Figures 1-3, the dispenser mainly comprises a top plate 1, two vertical end plates 2 and a horizontal bottom plate 3, etc. Among them, the top plate 1 is located above the bottom plate 3, and 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 all sealed and welded, together forming the main body of the dispenser.

[0021] Preferably, the top plate 1 is made of a metal sheet and is in a bent shape, with a bending angle of 120°.

[0022] A plurality of liquid outlet holes 4 are arranged on the top plate 1, and a liquid inlet 5 is arranged on the bottom of the bottom plate 3, and the bottom of the liquid inlet 5 is connected with a liquid inlet connecting pipe 7 for connecting a liquid inlet pipe. Thus, liquid can be introduced into the dispenser through the liquid inlet pipe and the liquid inlet 5, and then discharged through the liquid outlet holes 4 on the top plate 1, so as to realize the dispensing effect of the dispenser.

[0023] In addition, a non-hole area 6 is arranged on the top plate 1 near the liquid inlet 5, and no liquid outlet hole 4 is arranged in the non-hole area 6. Thus, the liquid introduced into the dispenser through the liquid inlet 5 can be prevented from directly flowing out of the dispenser without being dispensed.

[0024] Preferably, the liquid outlet holes 4 on the top plate 1 are circular, square or triangular, wherein the diameter of the circular liquid outlet hole 4 is 3-8 mm, and the equivalent diameter of the square or triangular liquid outlet hole 4 is 3-8 mm.

[0025] Preferably, the diameter of the liquid inlet 5 is 35-80 mm, and more preferably 54 mm. The length of the non-hole area 6 is preferably twice the diameter of the liquid inlet 5, i.e. 108 mm.

[0026] 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, so as to ensure that the dispenser can be dispensed in time, and liquid accumulation is avoided.

[0027] The above only describes some embodiments of the present disclosure. Those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
