Detailed description of the invention

With detailed description of the invention, this utility model is made the most below in conjunction with the accompanying drawings Bright:

Fig. 1 to Fig. 3 is schematic diagram of the present utility model.A kind of cooling machine cabinet air conditioning system pipe Road design structure, including rack 1, cabinet air conditioner 2, collector 3 and multiple arm 4, collection Pipe 3 includes liquid pipe collector and trachea collector, and arm 4 includes arm liquid pipe and arm trachea, Collector 3 in Fig. 1 has two, and one is trachea collector, and another is liquid pipe collector, root Need to be determined according to actual installation；Arm 4 also has two, respectively liquid pipe and trachea, Need to be determined also according to actual installation.Arm liquid pipe connects with collector liquid pipe, arm Trachea connects with collector trachea, and described collector 3 is for be disposed in the interior cabinet air conditioner group top Long siphunculus.

Collector liquid pipe liquid is uniform to multiple arm liquid pipe separatory: collector liquid length of tube is longer Time, it is ensured that end branch tube liquid pipe separatory is sufficient.Its principle analysis is:

For the pipeline of steady flow, to any two cross section:

$\mathrm{\Δ}P=\frac{G^2}{\mathrm{\Δ}\mathrm{\ρ}}+\frac{{\mathrm{\λ}}_M{G}^{2}L}{2{\mathrm{D\ρ}}_M}=(\frac{1}{\mathrm{\Δ}\mathrm{\ρ}}+\frac{{\mathrm{\λ}}_{M}L}{2{\mathrm{D\ρ}}_M})\·G^2=K\·G^2$

Wherein △ P is two cross section pressure reduction, and G is mass flow, and K is and line size, stream The numerical value that body density, coefficient of pipe friction are relevant.When line size, fluid, pipe material Etc. time identical, K is definite value.

(1) when stretching out bottom arm, because of action of gravity, its △ P value is more than protruding horizontally up Situation, when therefore stretching out bottom arm, in arm, mass flow protrudes horizontally up more than arm Pattern.

(2) along with collection pipe fluid flowing, △ P reduce, i.e. in arm mass flow with collector Interior flow direction is fewer and feweri.

(3) comprehensive above analysis, when supplying flow quantity equal in collector, flow direction front end Bottom stretch out arm mass flow and compare that to protrude horizontally up arm flow big, then can cause at collection The mass flow that the arm stretched out bottom pipe end is assigned to is compared and is protruded horizontally up arm flow Little.When header tube is longer, can cause stretching out arm almost without separatory bottom manifold end； When arm protrudes horizontally up, collector front portion is little to end separatory mass flow difference, separatory effect Preferably.

As in figure 2 it is shown, the side on long siphunculus has hole connects each arm, each arm 4 points It is not connected to collector 5 same side, and protrudes horizontally up.

Arm connects from collector side, and connecting portion arm protrudes horizontally up, multiple arm tracheas It is without hindrance that gas flows into collector trachea.Its principle analysis is: be filled with refrigeration in cabinet air conditioner Agent, the vapor phase refrigerant degree of superheat that its outfan is discharged is less, by arm trachea to collector During trachea, the reduction of pressure, cause a little cold-producing medium to condense, bottom trachea, form liquid layer； When arm trachea connects bottom collector trachea, liquid layer hinders gas to flow into collector from arm, Cause system circulation the most smooth；Protrude horizontally up and can be prevented effectively from the gas stream formed because of layer of condensate Dynamic obstruction.

As it is shown on figure 3, indoor machine cabinet air-conditioning is provided with input/output terminal 5, input and arm Liquid pipe connects, and the outfan of cabinet air conditioner 2 connects with arm trachea.Arm trachea, arm Liquid pipe exports to indoor machine cabinet air-conditioning 2, be provided with belt switch and maintenance function between input Connection member, can apply but be not limited only to stop valve, in collector and arm, be provided with freon.

Arm trachea, arm liquid pipe export to cabinet air conditioner, is provided with band between input opens Close and the connection member of maintenance function, can apply but be not limited only to stop valve, it is achieved rack is empty The cold adjusted individually controls and independent maintenance.

Collector is arranged in cooling machine cabinet air conditioning system top, and employing is walked pipe mode, saves sky Between, rack is high without frame, improves air conditioner in machine room utilization ratio.
