Abstract

The present application discloses an evaporator and a liquid blocking device thereof. The liquid blocking device includes: a body, which has a plate-shaped first separator extending in a longitudinal direction, the first separator having a plurality of holes, and the plurality of holes communicating an exterior of the body with an interior of the body; and a second separator attached to the body, the second separator being configured to have a plurality of openings which abut each other, so that a pressure drop generated when a fluid passes through the second separator via the openings is less than a pressure drop generated when the fluid passes through the first separator. The present application can improve the effect of gas-liquid separation.

First claim

What is claimed is:

1. A liquid blocking device for an evaporator, comprising:
a body ( 10 ), which has a plate-shaped first separator ( 11 ) extending in a longitudinal direction, the first separator ( 11 ) having a plurality of holes ( 28 ), and the plurality of holes ( 28 ) communicating an exterior of the body ( 10 ) with an interior of the body ( 10 ); and
a second separator ( 12 ) attached to the body ( 10 ), the second separator ( 12 ) being configured to have a plurality of openings ( 29 ) which abut each other, so that a pressure drop generated when a fluid passes through the second separator ( 12 ) via the openings ( 29 ) is less than a pressure drop generated when the fluid passes through the first separator ( 12 );
wherein the body ( 10 ) has a bottom portion ( 15 ) and two opposite side portions ( 16 ), and the bottom portion ( 15 ) is configured to have a solid plate shape to prevent fluid from entering the interior from the exterior of the body ( 10 ); the combined first separator ( 11 ) and second separator ( 12 ) are disposed on the side portions ( 16 ).

2. The liquid blocking device according to claim 1 , wherein the plurality of openings ( 29 ) are distributed throughout the second separator ( 12 ).

3. The liquid blocking device according to claim 1 , wherein the second separator ( 12 ) is formed into a mesh shape.

4. The liquid blocking device according to claim 3 , wherein the second separator ( 12 ) is a wire mesh made of metal.

5. The liquid blocking device according to claim 1 , wherein the second separator ( 12 ) is disposed on the exterior of the body ( 10 ), so that the fluid passes through the second separator ( 12 ) and then passes through the first separator ( 11 ); or the second separator ( 12 ) is disposed in the interior of the body ( 10 ), so that the fluid passing through the first separator ( 11 ) passes through the second separator ( 12 ).

6. The liquid blocking device according to claim 1 , wherein the first separator ( 11 ) and the second separator ( 12 ) are integrated together, or the first separator ( 11 ) and the second separator ( 12 ) are provided separately.

7. The liquid blocking device according to claim 1 , wherein the second separator ( 12 ) is composed of at least one section, and the at least one section is configured to surround the body ( 10 ) in a circumferential direction.

8. An evaporator, comprising:
an inlet ( 122 ), via which a refrigerant enters the inside of the evaporator; and
an outlet ( 123 ), wherein the refrigerant exits from the inside of the evaporator via the outlet ( 123 );
wherein the evaporator further comprises:
the liquid blocking device according to claim 1 , which is provided at the outlet ( 123 ).

9. A liquid blocking device for an evaporator, comprising:
a body ( 10 ), which has a plate-shaped first separator ( 11 ) extending in a longitudinal direction, the first separator ( 11 ) having a plurality of holes ( 28 ), and the plurality of holes ( 28 ) communicating an exterior of the body ( 10 ) with an interior of the body ( 10 ); and
a second separator ( 12 ) attached to the body ( 10 ), the second separator ( 12 ) being configured to have a plurality of openings ( 29 ) which abut each other, so that a pressure drop generated when a fluid passes through the second separator ( 12 ) via the openings ( 29 ) is less than a pressure drop generated when the fluid passes through the first separator ( 12 );
wherein the plurality of holes ( 28 ) of the first separator ( 11 ) are divided into at least a first hole area ( 61 ), a second hole area ( 62 ), and a third hole area ( 63 ); and wherein each of the first hole area ( 61 ), the second hole area ( 62 ) and the third hole area ( 63 ) has a hole array ( 71 , 72 , 73 ), and the plurality of openings ( 29 ) of the second separator ( 12 ) overlap with at least one of the hole arrays ( 71 , 72 , 73 ).
