Abstract

A heat exchanger ( 100 ) comprises: a first header tube ( 1 ) and two second header tubes ( 3 ); a first heat exchange tube ( 51 ) in fluid communication with one of the two second header tubes ( 3 ) and a second chamber (B) of the first header tube ( 1 ); a first runner tube ( 61 ) in fluid communication with the one of two second header tubes ( 3 ) and a first chamber (A) of the first header tube ( 1 ); a second heat exchange tube ( 52 ) in fluid communication with the other of the two second header tubes ( 3 ) and the first chamber (A) of the first header tube ( 1 ); and a second runner tube ( 62 ) in fluid communication with the other of the two second header tubes ( 3 ) and the second chamber (B) of the first header tube ( 1 ). The heat exchanger ( 100 ) bends at a first bending portion ( 71 ) between the other of the two second header tubes ( 3 ) and the first header tube ( 1 ), so as to enable the other of the two second header tubes ( 3 ) to be higher or lower than the first header tube ( 1 ).

2. The heat exchanger as claimed in claim 1 , wherein

said heat exchanger is bent at a second bent portion between said one of said two second headers and said first header so that said one of said two second headers is lower or higher than said first header.

3. The heat exchanger as claimed in claim 1 , wherein

before the heat exchanger is bent, said first header is provided between said two second headers, and the first heat exchange pipes, first communicating pipes, second heat exchange pipes, and second communicating pipes extend roughly in the same direction.

4. The heat exchanger as claimed in claim 1 , wherein

a refrigerant can flow from the first heat exchange pipes through said one of said two second headers and the first communicating pipes to the first chamber of said first header, then can flow from the first chamber of said first header to the second heat exchange pipes, and can flow from the second heat exchange pipes through said the other one of said two second headers and the second communicating pipes into the second chamber of said first header.

5. The heat exchanger as claimed in claim 1 , wherein

a refrigerant is sealed in the heat exchanger and is circulated only in the heat exchanger.

6. The heat exchanger as claimed in claim 1 , wherein

the first heat exchange pipes are connected to the first communicating pipes by connecting portions to form integral parts, and/or

the second heat exchange pipes are connected to the second communicating pipes by connecting portions to form integral parts.

7. The heat exchanger as claimed in claim 1 , wherein

a section of both the second heat exchange pipes and the second communicating pipes between said first bent portion and said the other one of said two second headers extends aslant upward or downward, or extends vertically upward or downward, from said first bent portion.

8. The heat exchanger as claimed in claim 1 , wherein

the first heat exchange pipes, the first communicating pipes, and a section of both the second heat exchange pipes and the second communicating pipes between said first bent portion and the first header extend roughly in a horizontal direction.

9. The heat exchanger as claimed in claim 2 , wherein

a section of both the first heat exchange pipes and the first communicating pipes between said second bent portion and said one of said two second headers extends aslant downward or upward, or extends vertically downward or upward, from said second bent portion.

10. The heat exchanger as claimed in claim 2 , wherein

a section of both the first heat exchange pipes and the first communicating pipes between said second bent portion and the first header and a section of both the second heat exchange pipes and the second communicating pipes between said first bent portion and the first header extend roughly in a horizontal direction or extend aslant.

11. The heat exchanger as claimed in claim 1 , wherein

the first bent portion is roughly parallel to the first header or said the other one of said two second headers.

12. The heat exchanger as claimed in claim 2 , wherein

the first bent portion is roughly parallel to the first header or said the other one of said two second headers, and

the second bent portion is roughly parallel to the first header or said one of said two second headers.

13. The heat exchanger as claimed in claim 1 , wherein

fins are provided between the first heat exchange pipes and between the second heat exchange pipes.
