Abstract
The utility model discloses a novel indoor air-conditioner auxiliary piping line. The novel indoor air-conditioner auxiliary piping line comprises a copper connector, a connection pipe, a distributor and a branch pipe, wherein a juncture of the copper connector and the connection pipe is provided with a filter screen component. The filter screen component installed at the juncture of the copper connector and the connection pipe can cut up bubbles, plays a role in buffering flow rate of coolants, not only reduces noise of flowing of coolants, but also avoids leakage quality hidden dangers caused by excessive welding spots. Besides, the middle section of the connection pipe is a corrugated pipe provided with screw-type rib strips, is not prone to deformation in installation, and facilitates installation of an air-conditioner. The corrugated pipe can buffer the flow rate of coolants, avoids vibration transmission, and reduces vibration and noise when an outdoor unit operates. In addition, the connection pipe used for connecting the copper connector and the distributor is a copper-aluminum clad pipe, consumption of copper is greatly reduced, and therefore the weight of the air-conditioner is reduced, and production cost is lowered.
Description
Technical field:
The utility model relates to a kind of air-conditioner technical field, especially relates to a kind of auxiliary piping of domestic air conditioning indoor heat converter.
Background technology:
The domestic air conditioning auxiliary piping does not possess the noise elimination filter function in the market, and the air-conditioning unit is very high to the noise requirement of indoor set, if abnormal sound will influence people's normal life; In order to abate the noise; Basically increase parts such as silencer, filter separately, not only loaded down with trivial details, the difficult assembling of manufacture craft, solder joint is many simultaneously; The hidden danger of quality that has coolant leakage, and cost is high.Air-conditioning system adopts the capillary module throttling more now; Because the throttle capillary tube of unit is on off-premises station; So refrigerant is the gas-liquid two-phase district,, there is flow noise hidden danger so before getting into capillary, produced a large amount of bubbles in the refrigerant before getting into the separatory capillary.In addition, when auxiliary piping and off-premises station are connected and installed, need shaping or bending, the pipeline easy deformation, partial design personnel increase spring to prevent the pipeline distortion.
The indoor set auxiliary piping generally uses copper pipe to connect; In recent years, the copper valency is too high, uses copper pipe very high as the cost of refrigeration system; Cause household electrical appliances manufacturing enterprise profit to descend; Therefore, from alleviating the air-conditioner overall weight, reducing the good and raising market competitiveness equal angles consideration of copper pipe use, it is very necessary to design a kind of novel auxiliary piping.
The utility model content:
The purpose of the utility model is the weak point that exists to prior art and a kind of new indoor machine auxiliary piping is provided; It has simple in structure, easy for installation, copper product consumption less, characteristics that production cost is low, can reduce the excessive problem of indoor set noise simultaneously.
For realizing above-mentioned purpose, the new indoor machine auxiliary piping of the utility model includes copper sleeve, tube connector, distributor and arm, and wherein, the junction of copper sleeve and tube connector is provided with screen modules.
Preferred as technique scheme, described screen modules is arranged in the through hole at copper sleeve middle part, is welded to form by screen pack and rack, and wherein, rack is closely attached on the interior step surface of through hole locatees.
Preferred as technique scheme, described tube connector is a copper aluminum composite pipes, and its outside is an oxygen-free copper, and inside is rustproof aluminum alloy, and the interlude of copper aluminum composite pipes is the bellows with screw type rib.
Preferred as technique scheme, described distributor is thin shelled tubular structure or brass throttle structure.
The beneficial effect of the utility model is: the screen modules that is arranged at the junction of copper sleeve and tube connector can be cut bubble broken; Play the effect of buffering refrigerant flow rate; Not only can reduce refrigerant flow noise, the leakage hidden danger of quality that can also avoid solder joint too much to cause.Secondly, the tube connector interlude is the bellows with screw type rib, during installation bending not yielding, not only make things convenient for air-conditioning to install, and bellows can also cushion the flow velocity of refrigerant, prevent that vibration from transmitting the noise and vibration when reducing the off-premises station operation.In addition, the tube connector that connects copper sleeve and distributor is a copper aluminum composite pipes, can significantly reduce the consumption of copper material, thereby alleviate air-conditioning weight, reduces production costs.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of existing auxiliary piping;
Fig. 2 is the structural representation of the utility model embodiment one;
Fig. 3 is the partial enlarged drawing at A place among Fig. 2;
Fig. 4 is the structural representation of the utility model embodiment two.
The specific embodiment:
See Fig. 2 and embodiment one shown in Figure 3: the new indoor machine auxiliary piping of the utility model includes copper sleeve 10, tube connector 20, distributor 30 and arm 40; Wherein, The junction of copper sleeve 10 and tube connector 20 is nested with screen modules, and screen modules is arranged in the through hole at copper sleeve 10 middle parts, is welded to form by the screen pack 50 of stainless steel and the rack 60 of brass material; Wherein, rack 60 is closely attached on location on the step surface 11 in the through hole.Tube connector 20 is a copper aluminum composite pipes, and its outside is an oxygen-free copper, and inside is rustproof aluminum alloy, and the interlude of copper aluminum composite pipes is the bellows with screw type rib.Distributor 30 is thin shelled tubular structure or brass throttle structure, and arm 40 is common copper tube or Red-copper Capillary Tube.
Material is that the tube connector 20 of copper aluminum composite pipes and the copper sleeve 10 of brass material weld together; Because the fusing point of copper aluminum composite pipes is low, select tin solder, because of the flowability of tin solder very strong; And not necessarily flow toward the high-temperature region; So adopt weld-ring to add scolder, avoid directly adding hot solder, heating region to weld-ring distance is 10 ~ 25mm.
In embodiment shown in Figure 4 two, the screen pack 50 among the direction of its screen pack 50 and the embodiment one is opposite, and all the other are identical with embodiment one, repeat no more here.
The above is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.
