Fig. 1 is the compressor air suction pipe connecting structure schematic diagram that the specific embodiment of the invention proposes.
In figure:
1, vaporizer; 2, liquid barrier; 3, sucking pipe; 4, dividing plate; 5, compressor.
Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, being the concrete structure of the compressor air suction tube structure that the present invention proposes, comprising the sucking pipe 3 for connecting compressor 5 and vaporizer 1, sucking pipe 3 can be straight tube can be also bend pipe, and sucking pipe 3 is bend pipe in the present embodiment.Sucking pipe 3 is generally steel pipe or copper pipe.
Eddy current is produced in the head-on collision of sucking pipe 3 inside in order to prevent the air-flow entering into sucking pipe 3 from the both sides of liquid barrier 2, the present invention is provided with a dividing plate 4 in one end that the inside of sucking pipe 3 is connected with vaporizer 1, and the tow channel gas flow point entering into the relative flowing of sucking pipe 3 from liquid barrier 2 both sides in vaporizer 1 is divided into the two-way air-flow of PARALLEL FLOW by dividing plate 4; The air-flow of one co-flow is merged into after the two-way air-flow of PARALLEL FLOW flows through the region at dividing plate 4 place.
As more concrete mode of execution, dividing plate 4 is arranged on the public tangent plane of the two-way air-flow of flowing relatively, and dividing plate 4 runs through sucking pipe 3 along the radial direction of sucking pipe 3.Pipeline near vaporizer 1 air outlet end is divided into two runners by such dividing plate 4, a runner is for supplying the air current flow entering into sucking pipe 3 on the left of liquid barrier 2, another runner is used for the air current flow for entering into sucking pipe 3 on the right side of liquid barrier 2, tow channel gas stream is separated, thus ensures not clash between two-way air-flow.
The length of dividing plate 4 is a predefined value, and predefined value can make the flow direction of the two-way air-flow of dividing plate 4 both sides become PARALLEL FLOW from relatively flowing.The length of dividing plate 4 based on experience value or the analogue value determine, as long as make after tow channel gas flows through the region at dividing plate 4 place, the flow direction of the air-flow of two-way becomes unanimously, head-on collision no longer occurs between the two and produces eddy current.In order to ensure stability and the uniformity of air current flow, the shape of dividing plate 4 is located at the region in sucking pipe 3 shape with it is suitable.Such as when sucking pipe 3 is bend pipe, the length of dividing plate 4 has extended to the bending part of sucking pipe 3, and so dividing plate 4 also should bend in position, to ensure that dividing plate 4 can not affect the flowing of air-flow.
As one preferred embodiment, the set-up mode of the dividing plate in the present embodiment also can be, the length of dividing plate extends along the axial direction of sucking pipe, axial direction herein refers to the length direction of sucking pipe, dividing plate extends to the other end of sucking pipe from one end of sucking pipe, namely how long the length of sucking pipe has, and how long dividing plate just has, and is all provided with dividing plate in whole sucking pipe.
Dividing plate 4 can adopt various ways to be fixed on sucking pipe, and the dividing plate 4 in the present embodiment adopts the mode of welding to be fixed on the inwall of sucking pipe 3.Dividing plate 4 can be copper coin or steel plate, and as preferred embodiment, the material of dividing plate 4 is identical with the material of sucking pipe 3.
In order to make the water conservancy diversion better effects if of dividing plate 4, dividing plate 4 is provided with flow guide structure, and flow guide structure is preferably guiding gutter, guiding gutter can the air-flow of better accessory septa both sides according to the flow passage formed between dividing plate 4 and sucking pipe 3 inwall.
As one preferred embodiment, dividing plate 4 is provided with corrosion-resistant coating, effectively can ensure that dividing plate 4 can not corrode by refrigerant gas.
The present invention arranges a dividing plate at sucking pipe near one end of vaporizer, and the tow channel gas flow point entering into the relative flowing of sucking pipe from the liquid barrier both sides in vaporizer is divided into the two-way air-flow of PARALLEL FLOW by dividing plate; Merge into the air-flow of one co-flow after the two-way air-flow of PARALLEL FLOW flows through the region at dividing plate place, can prevent the gas entering into sucking pipe from forming eddy current, reduce the pressure of inspiration(Pi) loss of compressor, promote unit cycle efficiency.
Air suction tube structure in the present invention simultaneously can also reduce absorbing gas belt liquid, reduces and is present in the infringement of the liquid in air-flow to compressor impeller.
Below describe know-why of the present invention in conjunction with specific embodiments, these describe just in order to explain principle of the present invention, can not be interpreted as limiting the scope of the invention by any way.Based on explaining herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present invention, and these modes all will fall within protection scope of the present invention.
