Abstract

A heat exchanger has a structure in which a heat exchanger main body through which coolant flows is obliquely installed in a box-shaped enclosure, the heat exchanger main body is constituted by a header pipe and a plurality of heat transfer pipes connected to the header pipe and disposed at predetermined intervals along a surface of a part of the header pipe, the header pipe has an area adjacent to an inner surface of the enclosure, and a seal section is provided between the inner surface of the enclosure and the area of the header pipe adjacent to the enclosure.

First claim

What is claimed is:

1 . A heat exchanger in which a heat exchanger main body through which coolant flows is obliquely installed in a box-shaped enclosure,
wherein the heat exchanger main body is constituted by a header pipe configured to perform supply and discharge of coolant, and a plurality of heat transfer pipes connected to the header pipe and disposed at predetermined intervals along a surface of part of the header pipe, the header pipe has an area adjacent to an inner surface of the enclosure, and a seal section is provided between the inner surface of the enclosure and the area of the header pipe adjacent to the enclosure.

2 . The heat exchanger according to claim 1 , wherein the seal section is formed of an elastically deformable material.

3 . The heat exchanger according to claim 1 , wherein the seal section is formed by a micro gap formed between the header pipe and the inner surface of the enclosure.

4 . The heat exchanger according to claim 1 , wherein the header pipe has places to which the heat transfer pipes are connected, the places each being formed in a flat surface shape.

5 . The heat exchanger according to claim 4 , wherein the header pipe has a portion formed in a curved surface shape other than the connecting places while a cross-sectional shape is formed in a quadrangular shape, and
the seal section is provided on a curved surface section of the header pipe.

6 . The heat exchanger according to claim 4 , wherein a ratio of a diameter of the heat transfer pipe with respect to a diameter of the header pipe at the connecting place is 0.5 or more and less than 1.

7 . The heat exchanger according to claim 1 , wherein, in the enclosure, air containing heat is suctioned from a lower opening disposed below the heat exchanger main body that is obliquely installed, and the air after cooling is discharged from an upper opening disposed above the heat exchanger main body.

8 . The heat exchanger according to claim 7 , wherein an air blower configured to supply the air into the enclosure is provided in the opening of the enclosure.

9 . The heat exchanger according to claim 1 , wherein a pressure of the coolant flowing through the heat exchanger main body is 0.5 atm or more and 3 atm or less.
