Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and more specifically to an irregularly shaped dispenser. Background Technology

[0002] In refrigeration equipment such as air conditioners and refrigerators, the shaped pipe distributor is a refrigerant collection component that can recover and reuse excess refrigerant. However, in existing technologies: ① a flattened figure-eight structure (i.e., using a flattening process, the tee end face is in the shape of an "∞") is used to isolate the small holes for branch pipes (forming a multi-channel structure). Flattening the middle channel of the tee can cause uneven gaps (because the middle connection points of the multi-channels are interconnected and the gaps are uneven), leading to welding leaks and poor load-bearing capacity; ② During the flattening process, local deformation of the material can easily lead to tearing of the base material, causing leakage; ③ The side holes of the tee use flanges, with an overlap length of only 1-1.5mm, resulting in poor connection strength. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a structurally sound and high-strength irregularly shaped distributor.

[0004] A non-standard distributor includes a connecting pipe, to which a first flat pipe and a second flat pipe are connected via a transition pipe. The second flat pipe has multiple branch pipe holes spaced at intervals, and each branch pipe hole communicates with a cavity in the first flat pipe. The cavity of the first flat pipe is also connected to the transition pipe and the connecting pipe. Refrigerant collected from the branch pipe holes flows through the first flat pipe and the transition pipe, and then exits from the connecting pipe. The connecting pipe, transition pipe, first flat pipe, and second flat pipe are integrally formed. A first limiting mechanism is provided on the branch pipe holes, and a second limiting mechanism is provided on the connecting pipe. The structure is reasonable, with high strength and load-bearing capacity. The holes are independent and do not interfere with each other, avoiding welding leaks caused by uneven gaps in the middle channel of the tee.

[0005] As a further improvement and supplement to the above solution, this utility model also includes the following additional technical features: The aforementioned connecting pipe, transition pipe, and first flat pipe are on the same axis. The structure is reasonable, with high strength and load-bearing capacity.

[0006] The first and second flat tubes are of waist-shaped or elliptical structure.

[0007] The first limiting mechanism consists of multiple arc-shaped protrusions, facilitating positioning.

[0008] The second limiting mechanism is a stepped hole, which facilitates positioning.

[0009] The first flat tube also has at least one boss on its side, and the boss has a tapered hole. This adds a collection hole from another direction, satisfying the usage requirements.

[0010] The boss is formed by flanging. The side holes are flanged both internally and externally to increase the overlap length and bonding strength of the branch pipe and the irregular-shaped distributor.

[0011] The aforementioned connecting pipe, transition pipe, first flat pipe, and second flat pipe are formed by cold forging and extrusion using T2 wire.

[0012] The following beneficial effects can be achieved by using this utility model: 1. Small-hole cold heading forming, with each hole independent and non-interfering, avoids welding leakage caused by uneven gaps in the middle channel of the T-junction.

[0013] 2. The side holes are fitted with inner and outer flanges to increase the overlap length and bonding strength of the branch pipes and irregularly shaped distributors.

[0014] 3. It adopts T2 wire cold heading process for extrusion molding, which eliminates the risk of cracking and leakage caused by localized concentrated deformation during the forming of flattened pipe tees.

[0015] 4. The structure is reasonable, with high strength and load-bearing capacity. Attached Figure Description

[0029] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1-13 As shown, this utility model is an irregularly shaped dispenser.

[0031] The irregular-shaped distributor described in this embodiment includes a connecting pipe 1 with a circular cross-section. A first flat pipe 3 and a second flat pipe 4 are connected to the connecting pipe 1 via a transition pipe 2. The transition pipe 2 has a tapered structure that gradually transitions from a circular shape to a flat pipe shape. The second flat pipe 4 has smaller dimensions than the first flat pipe 3. The second flat pipe 4 has multiple branch pipe holes 41 spaced apart, and each branch pipe hole 41 communicates with the cavity of the first flat pipe 3. The cavity of the first flat pipe 3 is also connected to the transition pipe 2 and the connecting pipe 1. Refrigerant collected from the branch pipe holes 41 flows through the first flat pipe 3 and the transition pipe 2 before exiting from the connecting pipe 1. The connecting pipe 1, transition pipe 2, first flat pipe 3, and second flat pipe 4 are integrally formed. A first limiting mechanism is provided on the branch pipe holes 41, and a second limiting mechanism is provided on the connecting pipe 1.

[0032] Furthermore, the connecting pipe 1, the transition pipe 2, and the first flat pipe 3 are on the same axis.

[0033] Furthermore, the first flat tube 3 and the second flat tube 4 are waist-shaped or elliptical structures, or other structures in the prior art.

[0034] Furthermore, the first limiting mechanism consists of multiple arc-shaped protrusions 42. In the first, second, and third embodiments, the number of arc-shaped protrusions 42 is 3. One side of the arc-shaped protrusion 42 is connected to the branch pipe hole 41, and the other side extends into the branch pipe hole 41.

[0035] Furthermore, the second limiting mechanism is a stepped hole 11.

[0036] Furthermore, the first flat tube 3 is provided with at least one boss 5 on its side, and the boss 5 is provided with a tapered hole 51, which eliminates the need for a positioning structure. In the second embodiment, the number of bosses 5 is one, and in the third embodiment, the number of bosses 5 is two, with the two bosses 5 spaced apart. The tapered hole 51 communicates with the cavity of the first flat tube 3.

[0037] Furthermore, the boss 5 is formed by flanging, which increases the overlap length and bonding strength of the branch pipe and the irregular-shaped distributor.

[0038] Furthermore, the aforementioned connector 1, transition pipe 2, first flat pipe 3, and second flat pipe 4 are formed by cold forging with T2 wire, eliminating the risk of cracking and leakage caused by localized concentrated deformation of wood during the forming of flattened tees.

[0039] When this irregularly shaped distributor is in use, corresponding branch pipes are welded to the branch pipe holes 41 and tapered holes 51, and round pipes are welded to the connecting pipe 1. The branch pipes connected to the branch pipe holes 41 and tapered holes 51 collect coolant, which flows out from the connecting pipe 1 after passing through the first flat pipe 3 and the transition pipe 2, and then flows back through the round pipe of the connecting pipe 1.

[0040] The above are preferred embodiments of the present utility model and do not limit the scope of protection of the present utility model. Any modifications and improvements made by those skilled in the art based on the design concept of the present utility model should be considered within the scope of protection of the present utility model.
