Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a heat exchanger in which a mounting member is attached to a header pipe of a heat exchanger used as a condenser of various cooling devices or a radiator for a vehicle. Things.

(Prior art) Conventionally, as a heat exchanger of this type, a mounting member for mounting a heat exchanger body is fastened to a header pipe through which a heat medium flows with screws or the like, or temporarily fixed with a special jig or the like. What is thrown into the furnace and brazed is known.

(Problems to be Solved by the Invention) However, when the mounting member is fastened to the header pipe, it is necessary to form a fastening member such as a screw and a portion to be fastened, so that the number of parts increases and the member becomes complicated. There is a drawback of inviting. In the case of brazing, the above-mentioned fastening members are not required, but the mounting members must be temporarily fixed using a dedicated jig or the like. There was a problem that it became complicated.

The present invention has been made in view of the above problems, and its purpose is to simplify the structure of the mounting member,
Moreover, an object of the present invention is to provide a heat exchanger that can be easily assembled.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a heat exchanger in which a mounting member for mounting a heat exchanger body is mounted on a header pipe through which a heat medium flows. At one end of the header pipe, in the thickness direction, using an attachment member that is bent into a curved shape along the inner surface of the header pipe and used as a locking portion, and the length of the header pipe on the side surface is the length in the longitudinal direction. A vertically long connection hole having a length corresponding to the width direction of one end of the attachment member was provided so that the longitudinal direction was along the axial direction of the header pipe.

According to the present invention, when the locking portion of the mounting member is inserted into the connection hole of the header pipe laid horizontally, the weight of the portion other than the locking portion of the mounting member causes the locking portion of the header pipe to be attached. It will be pressed against the inner side surface, so that the mounting member is fixedly held at a predetermined position of the header pipe, so that the mounting member is directly It can be attached to the header pipe by brazing or the like. Also, at this time, the locking portion of the mounting member having a shape curved along the inner surface of the header pipe,
The heat pipe is assembled while being pressed against the inner surface of the header pipe. That is, since the inside diameter of a part of the header pipe is only reduced by the thickness of the mounting member, the flow of the heat medium in the header pipe may be hindered. Almost no.

(Embodiment) FIGS. 1 to 3 show an embodiment of the present invention.

In the figure, reference numeral 1 denotes two header pipes arranged in parallel at a predetermined interval, the upper and lower ends of which are respectively sealed by lids 1a, a heat medium inlet 1b on one upper side, and a lower side on the other side. A heat medium outlet 1c is provided on each side surface. In addition, vertically long connection holes 1d for inserting one end of a mounting member 4 described later are formed in upper and lower sides of each header pipe, respectively.

Numeral 2 denotes a plurality of flat tubes, both ends of which are inserted and connected to the side surfaces of the header pipes 1, respectively, so that the heat medium can flow between the header pipes 1.

Numeral 3 is a heat transfer fin formed of a corrugated thin plate, which is interposed between the tubes 2 arranged in parallel, and whose upper and lower ends are fixed to the tubes 2.

Reference numeral 4 denotes a total of four mounting members for mounting the heat exchanger body, a notch 4a for inserting a mounting bolt (not shown) or the like at one end, and a connection hole 1d for the header pipe 1 at the other end. Locking portions 4b, which can be inserted into the respective sections. The locking portion 4b has a curved shape along the inner surface of the header pipe 1,
The engagement allows the attachment member 4 to be positioned in a state of extending to the side of the header pipe 1.

When assembling each mounting member 4 to the header pipe 1,
First, by inserting the locking portion 4b of the mounting member 4 into the connection hole 1d of the header pipe 1 laid horizontally, the mounting member 4
The locking portion 2b is locked to a part of the inner surface of the header pipe 1 by the weight of the non-inserted portion, and the mounting member 4 is held in a positioned state. At this time, since the locking portion 4b of the mounting member 4 is curved along the inner surface of the header pipe 1, the one surface of the locking portion 4b and the inner surface of the header pipe 1 Is in surface contact with the inner surface of the substrate through a brazing material previously clad. Then, by throwing into the furnace in this locked state, the locking portion 4b is brazed and the mounting member 4 is assembled.

As described above, according to the heat exchanger of the present embodiment, the locking portion 4b that can be inserted into the connection hole 1d of the header pipe 1 is attached to the mounting member 4.
Is provided so that the mounting member 4 can be held in a positioned state by locking the locking portion 4b and the inner surface of the header pipe 1 laid horizontally, so that a jig or the like for temporary fixing is not required. Brazing in a furnace becomes possible. Therefore, not only can the attachment member 4 be assembled extremely easily, but also no fastening member or the like is required, and the number of parts can be reduced and the structure can be simplified. Furthermore, the locking portion of the mounting member 4
4b is formed so as to be curved along the inner surface of the header pipe 1, so that the surface in the thickness direction of the locking portion 4b faces the inner surface of the header pipe 1. The attachment member 4 can be attached to the header pipe 1 at any position in the direction of the passage of the heat medium without the flow of the heat medium being hindered by the attachment member 4.

(Effects of the Invention) As described above, according to the heat exchanger of the present invention, brazing in the furnace can be performed without the need for a temporary fixing jig or the like. Not only can it be easily performed, but also no fastening member or the like is required at all, which can contribute to a reduction in the number of parts and simplification of the structure. Further, since the flow of the heat medium in the header pipe is not hindered by the mounting member, the mounting member can be mounted at any position in the direction of the flow of the heat medium of the header pipe.
