Abstract

PURPOSE:To obtain a heat exchanger provided with a header which has a high productivity and a superior pressure proof strength by providing the header with a plane part in the inside of the connected part of one plate material and the other plate material, and jointing the plane part with the side face of a tube. CONSTITUTION:A header 4 is constituted of one plate material 5 which is bent nearly in U-shape in the cross section and the other plate material 6 which is bent nearly in U-shape in the cross section. In more detail, a plate part 8 formed on both the ends of the other plate material 6 is superposed on the inside of a plate part 7 formed on both the ends of the one plate material 5 and this superposed part is joined by brazing. The interval of the plate part 8 of both the ends of the other plate material 6 is formed in the same size as the width of a tube 2 and at the time of assembling both the side faces of the tube 2 are touched on the inside of the plate part 8 or positioned immediately before the touch thereof in a condition to insert the tube 2 in a tube- inserted hole 9 of a header 4. As the result, the inside of the plate part 8 and both the side faces of the tube 2 are joined by brazing each other.

[Prior Art] As a conventional heat exchanger, a technique disclosed in Japanese Patent Application Laid-Open No. 161394/1983 is known. This technology involves inserting a tube whose surface is clad with brazing material into an insertion hole formed in a cylindrical header, and then brazing the tube and header in this inserted state to join and secure the tube and header.

[The press work to form an insertion hole in the 'ajllll pipe that the invention seeks to solve involves inserting a female die into the pipe, then opening the insertion hole by press work, and then extracting the female die from the pipe. It becomes more. In particular, when removing the female mold from the pipe, the particles generated when forming the insertion hole get caught in the female mold, making it difficult to extract the female mold from the pipe.In other words, conventional headers have an insertion hole formed in the pipe. It was difficult to form a header with an insertion hole.

On the other hand, by forming the interval between the flat plate parts 8 at both ends of the other flat plate material 6 to be the same size as the width of the duplex 2, the interval between the flat plate parts ff17 at both ends of the one flat plate material 5 is also narrowed, and as a result, the header 4 is provided with a small diameter. In other words, the curvature ratio of the arcuate portion of the other flat plate member 6 is increased. As a result,
As shown in FIG. 1, even if the end of the tube 2 is brought into contact with the arcuate portion of the other flat plate 6, there will be a relatively large gap between the end of the tube 2 and the other flat plate 6. Can take up a large area. This area is sufficient to allow the refrigerant to flow without any inconvenience, so the positioning of the tube 2 and header 4 can be done by bringing the tube 2 into contact with the arcuate part of the other flat plate 6 during assembly. It can be carried out. In other words,
When assembling, even if the end of the tube 2 is casually inserted into the tube insertion hole 9, the end of the tube 2 hits the inner wall of the header 4, and the positional relationship between the tube 2 and the header 4 is easily determined.

The gas refrigerant introduced into the inflow pipe 1.1 passes through the inflow chamber in one header 4, the tube 2 communicating with the inflow chamber, the other header 4, the tube 2 communicating with the outflow chamber, and the outflow pipe via the outflow chamber. It flows out from 12. When the refrigerant flows through the tube 2 led from the inflow chamber to the other header 4 and through the tube 2 led from the other header 4 to the outflow chamber, heat is exchanged with the air passing between the corrugated fins 3. , liquefy, condense. Therefore, the gas refrigerant introduced into the inflow pipe 11 flows out from the outflow pipe 12 as a liquid refrigerant.

On the other hand, since the refrigerant condenser 1 is disposed upstream of the pressure reducing device, high pressure is applied to the inside of the header 4. For this reason, the header 4 is subjected to a large force that expands around the entire circumference. However, since the flat plate portion 8 formed at the V# end of the other flat plate member 6 that connects the header 4 to the tank bottom is joined to both open faces of the tube 2 by brazing, the duplex 2
prevents both end portions of the other flat plate member 6 from expanding. The flat plate portions 8 at both ends of the other flat plate material 6 are joint locations with the flat plate portions 7 at both ends of the one flat plate material 5. For this reason, header 4
Even if a high pressure is applied inside, the joint between the flat plate material 5 on one side and the flat plate material 6 on the other side is prevented from expanding.

As a result, the joint between the flat plate material 5 on one side and the flat plate material 6 on the other side is prevented from being damaged by the high force applied inside the header 4. Note that the parts other than the connection point are approximately constant. Because it draws an arc of curvature, it will not break even if high pressure is applied.

Furthermore, as described above, by forming the interval between the flat plate portions 8 of the other flat plate member 6 to have the same dimension as the width of the tube 2,
The curvature of one flat plate material 5 and the other flat plate material 6 is increased, and the header 4 is provided with a small diameter. Thereby, the maximum dimension of the header 4 in the depth direction (the width direction of the tube 2) can be reduced, and as a result, the refrigerant condenser 1 can be formed thin.
