Abstract

The utility model discloses a shunt for an air-conditioning heat exchanger. The shunt comprises a casting body, wherein a liquid inlet hole is arranged at one end of the casting body, a restrictor ring is arranged in the liquid inlet hole, the inner diameter of the restrictor ring is smaller than that of the liquid inlet hole, a tapered throttle angle is arranged at the position of the inside of the casting body, the position aligns to the restrictor ring, at least two shunt pipes are radially distributed on the periphery of the throttle angle along the circumference, openings of the shunt pipes are expanded to shunt ports, the angle of the throttle angle is less than or equal to 90 degrees, and the ratio of the inner diameter r1 of the restrictor ring and the inner diameter r2 of the liquid inlet hole is 1/15-1/5. By the aid of the shunt, the quick and even shunting actions of a refrigerant are achieved.

Description

Current divider

Technical field

The utility model relates to a kind of current divider, especially the current divider used of air-condition heat exchanger.

Background technology

Air-condition heat exchanger normally is comprised of fin and copper pipe, and copper pipe and fin are combined closely, copper pipe internal flow cooling agent wherein, by and fin between the heat conduction finish heat exchange.And several copper pipes have often been interted in heat exchanger, if heat exchanger area is larger, then copper pipe quantity can be much dozens or even hundreds of, often need to arrange copper pipe in parallel this time, what flow in every copper pipe all is just out cooling agent in the compressor, to obtain better heat exchanger effectiveness.

The used distinguished and admirable method of cooling agent normally is divided into some tubules with a supervisor at present, uses the tubule connecting copper pipe again, and such method operation is fairly simple, but tends to cause the shunting of cooling agent inhomogeneous, further causes the reduction of heat exchange efficiency.

The utility model content

The utility model is for the problems referred to above, and purpose is to provide a kind of current divider, makes from supervisor's cooling agent out and can be split into uniformly some branch roads, reaches preferably heat transfer effect.

The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of current divider, comprise the foundry goods main body, and foundry goods main body one end is provided with inlet opening, is provided with a restrictor ring in the inlet opening, and the internal diameter of described restrictor ring is less than the internal diameter of inlet opening; The foundry goods body interior is provided with the throttling angle of a cone over against restrictor ring, is radially distributed with at least 2 isocons along circumference around the throttling angle, and the opening part of isocon enlarges into diffluence pass.

As the further setting of such scheme, the angle at described throttling angle is less than or equal to 90 °.

As the further setting of such scheme, the ratio of the internal diameter r1 of described restrictor ring and the internal diameter r2 of inlet opening is 1/15～1/5.

As the further setting of such scheme, the ratio of the internal diameter r1 of described restrictor ring and the internal diameter r2 of inlet opening is 1/10.

The beneficial effects of the utility model are: be provided with restrictor ring in the inlet opening of the present utility model, and the internal diameter of restrictor ring is less than the inlet opening internal diameter, so when cooling agent flows into restrictor ring, it is large that flow velocity and pressure all can become, the exit of restrictor ring is over against the throttling angle of cone, can with cooling agent rapidly to around Uniform Dispersion, isocon evenly is arranged on the foundry goods body interior, can realize cooling agent fast, uniform shunting action, thereby the utlity model has and make cooling agent shunt uniform effect.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in the figure, a kind of current divider comprises foundry goods main body 1, and foundry goods main body 1 one ends are provided with inlet opening 4, is provided with a restrictor ring 3 in the inlet opening 4, and the internal diameter of described restrictor ring 3 is less than the internal diameter of inlet opening 4; Foundry goods main body 1 inside is provided with the throttling angle 5 of a cone over against restrictor ring 3, is radially distributed with at least 2 isocons 6 along circumference around the throttling angle 5, and the opening part of isocon 6 enlarges into diffluence pass 2.

As the further setting of such scheme, the angle at described throttling angle 5 is less than or equal to 90 °.

As the further setting of such scheme, the ratio of the internal diameter r1 of described restrictor ring 3 and the internal diameter r2 of inlet opening 4 is 1/15～1/5.

As the further setting of such scheme, the ratio of the internal diameter r1 of described restrictor ring 3 and the internal diameter r2 of inlet opening 4 is 1/10.

Operation principle of the present utility model is: 4 are provided with restrictor ring 3 in the inlet opening of the present utility model, and the internal diameter of restrictor ring 3 is less than inlet opening 4 internal diameters, so when cooling agent flows into restrictor ring 3, it is large that flow velocity and pressure all can become, the exit of restrictor ring 3 is over against the throttling angle 5 of cone, can with cooling agent rapidly to around Uniform Dispersion, isocon evenly is arranged on foundry goods main body 1 inside, can realize cooling agent fast, uniform shunting action.
