Abstract

PURPOSE:To provide a laminated heat exchanger in which a lack, etc., of a flux of a collar part can be prevented. CONSTITUTION:A laminated heat exchanger is formed of two plates 11' having a channel recess 11b and an exit/entrance hole 11c in combination, and a plurality of tube elements having heat exchanging medium channels are laminated. A collar 11f for brazing plates to a peripheral edge of the plate 11' is formed and a rib 11g for forming a flux reservoir S1 is formed on a connecting outside of the collar 11a, and hence, when a temporary assembly after coating with flux is conveyed for a brazing furnace, even if its outer surface is erroneously brought into contact with an operator, a peripheral equipment, etc., the collar 11f is received with the reservoir S1, and protected to effectively prevent lack, etc., of the flux.

In the embodiment illustrated in FIGS. 1 to 3,
Although the flux reservoir S1 is defined by the oblique ribs 11g, as shown in FIG. 4, the rib 11h of the plate is provided with a rib 11h that is bent in an L shape from the tip thereof along the flange 11f. According to the rib 11h, when the plates are combined to form the tube element, the flux reservoir S2 having a U-shaped cross section can be defined outside the joint surface of the collar 11h. Further, as shown in FIG. 5, a rib 11i extending in an inverted L shape from the tip of the flange 11f of one plate may be provided along the flange 11f. According to the rib 11i, plates are combined. When the tube element is constructed, a flux reservoir S3 having a U-shaped cross section can be defined outside the joint surface of the collar 11h. It goes without saying that the same action and effect can be obtained in any case.

As described in detail above, according to the present invention,
The ribs provided on the flange around the plate can define a flux reservoir that receives and protects the flux in the flange, so the outer surface of the temporary assembly after the flux is applied to the brazing furnace is erroneously exposed when the temporary assembly is transported to the brazing furnace. Even if it touches or the surrounding equipment, the flux in the same portion is not scraped or missing, and it is possible to reliably prevent defective brazing due to insufficient flux.
