Abstract

A flow disturbance apparatus includes: a refrigerant pipe having a flow space in which refrigerant flows; and at least one disturbance member disposed inside the refrigerant pipe that is vibrated by the flow of refrigerant in the refrigerant pipe to disturb the refrigerant flowing in the refrigerant pipe.

First claim

The invention claimed is:

1. A flow disturbance apparatus, comprising:
a refrigerant pipe having a flow space in which refrigerant flows; and
at least one disturbance member disposed inside of the refrigerant pipe, wherein the at least one disturbance member is vibrated by a flow of refrigerant in the refrigerant pipe to disturb the refrigerant flowing in the refrigerant pipe, wherein a first end of the at least one disturbance member is a fixed end connected to an inner surface of the refrigerant pipe, and a second end of the at least one disturbance member is a free end positioned in the flow space of the refrigerant pipe, wherein the at least one disturbance member comprises:
a blade portion having a predetermined width; and
a connecting portion having a smaller width than the blade portion, wherein a boundary between the blade portion and the connecting portion includes a step, and wherein a length of the blade portion is greater than a length of the connecting portion, and wherein the connecting portion has a higher elasticity than the blade portion.

2. The flow disturbance apparatus of claim 1 , wherein, in a direction of refrigerant flow, the fixed end of the at least one disturbance member is disposed downstream of the free end of the at least one disturbance member.

3. The flow disturbance apparatus of claim 1 , wherein the blade portion is disposed closer to a center of the refrigerant pipe than the connecting portion.

4. The flow disturbance apparatus of claim 1 , wherein the at least one disturbance member comprises a flexible material.

5. The flow disturbance apparatus of claim 1 , wherein the at least one disturbance member comprises:
a plurality of upper disturbance members disposed in the direction of refrigerant flow on a first side of the refrigerant pipe; and
a plurality of lower disturbance members disposed in the direction of refrigerant flow on a second side facing the first side of the refrigerant pipe, and wherein fixed ends of the plurality of upper disturbance members and fixed ends of the plurality of lower disturbance members do not overlap vertically.

6. The flow disturbance apparatus of claim 1 , wherein the at least one disturbance member comprises a plurality of disturbance members disposed at intervals on a virtual spiral line formed on the inner surface of the refrigerant pipe.

7. The flow disturbance apparatus of claim 6 , wherein the plurality of disturbance members is disposed in such a way as not to overlap within one cycle of the spiral line, when viewed in the direction of refrigerant flow.

8. The flow disturbance apparatus of claim 1 , wherein the at least one disturbance member has a curvature.

9. The flow disturbance apparatus of claim 1 , wherein the refrigerant pipe comprises a bent region in which the direction of refrigerant flow is switched, and the at least one disturbance member is disposed in the bent region.

10. The flow disturbance apparatus of claim 1 , further comprising at least one disturbance groove formed on an inner surface of the refrigerant pipe to disturb the refrigerant.

11. The flow disturbance apparatus of claim 10 , wherein the at least one disturbance groove is disposed in such a way as not to overlap the at least one disturbance member in a frontward-backward direction.

12. The flow disturbance apparatus of claim 10 , wherein a length of the at least one disturbance member is smaller than a radius of the refrigerant pipe.

13. An air conditioner comprising the flow disturbance apparatus of claim 1 .

14. An air conditioner, comprising:
a compressor that compresses refrigerant;
an outdoor heat exchanger that is installed outdoors and exchanges heat between outdoor air and the refrigerant;
an indoor heat exchanger that is installed indoors and exchanges heat between indoor air and the refrigerant; and
a flow disturbance apparatus that disturbs the refrigerant flowing inside of the air conditioner, wherein the flow disturbance apparatus comprises:
a refrigerant pipe having a flow space in which refrigerant flows; and
at least one disturbance member disposed inside of the refrigerant pipe, wherein the at least one disturbance member is vibrated by a flow of refrigerant in the refrigerant pipe to disturb the refrigerant flowing in the refrigerant pipe, wherein a first end of the at least one disturbance member is a fixed end connected to an inner surface of the refrigerant pipe, and a second end of the at least one disturbance member is a free end positioned in the flow space of the refrigerant pipe, and wherein the at least one disturbance member comprises:
a blade portion having a predetermined width; and
a connecting portion having a smaller width than the blade portion, wherein a boundary between the blade portion and the connecting portion includes a step, wherein a length of the blade portion is greater than a length of the connecting portion, and wherein the connecting portion has a higher elasticity than the blade portion.

15. The air conditioner of claim 14 , wherein, in a direction of refrigerant flow, the fixed end of the at least one disturbance member is disposed downstream of the free end of the at least one disturbance member.

16. The air conditioner of claim 14 , wherein the blade portion is disposed closer to a center of the refrigerant pipe than the connecting portion.

17. The air conditioner of claim 14 , wherein the at least one disturbance member comprises a flexible material.

18. The air conditioner of claim 14 , wherein the at least one disturbance member comprises:
a plurality of upper disturbance members disposed in the direction of refrigerant flow on a first side of the refrigerant pipe; and
a plurality of lower disturbance members disposed in the direction of refrigerant flow on a second side facing the first side of the refrigerant pipe, and wherein fixed ends of the plurality of upper disturbance members and fixed ends of the plurality of lower disturbance members do not overlap vertically.
