欠点がある。 Conventional protection plates for heat exchangers are flat metal protection plates, in which metal fins are placed upright on a metal substrate, and the flat metal protection plate is further provided on top of the metal fins to assemble the heat exchanger. Form a solid and divide this assembly into 1
Since productivity is not good if they are brazed one by one, multiple assemblies are laminated and brazed. However, in this conventional assembly using a heat exchanger protection plate, the top surface of the assembly is flat. Because it is a metal protection plate, if multiple assemblies are laminated and brazed together, the solder metal will be laminated due to capillary action and the vertically adjacent assemblies will be bonded together by the solder. There is a drawback that the attached heat exchanger and the heat exchanger become stuck together due to the wax.

着しないことを目的としたものである。 This invention solves the above-mentioned drawbacks when building heat exchangers by laminating and brazing heat exchanger assemblies using conventional heat exchanger protection plates, and allows multiple heat exchanger assemblies to be assembled. The purpose of this is to prevent heat exchangers made by laminating and brazing the heat exchangers from being stuck together by the solder.

けすることができる。 When actually assembling and brazing a heat exchanger using the heat exchanger protection plate 3 of this embodiment, it is necessary to First, an aluminum alloy corrugated fin 2 clad with brazing filler metal on both sides is provided, and an aluminum alloy base material 1 is provided below the fin 2 to assemble one unit of a heat exchanger. then 1
A plurality of unit heat exchanger assemblies are stacked and fixed with a jig, and then brazed in a furnace. During this brazing, the protective plate 3 that constitutes the heat exchanger assembly is
There is a continuous protrusion 4 with a height of 0.4 mm approximately 1 mm inward from both edges of the upper surface, so that the protective plate 3 of one vertically adjacent assembly and the substrate 1 of the other assembly are vertically adjacent to each other.
The melted wax does not cause capillary action, that is, the vertically adjacent assemblies are not fixed together by the wax, and each heat exchanger set is stacked as shown in Figure 2. Solids can be brazed.

状などの形状でもよい。 In this embodiment, a protection plate for a heat exchanger is described in which a protrusion is provided in the longitudinal direction of the metal protection plate, but a metal protection plate in which the protrusion is provided in a direction perpendicular to the longitudinal direction of the protection plate is also described. Alternatively, rounded protrusions may be provided on the upper surface of both longitudinal edges of the protection plate (the tips of the protrusions are located slightly inside the edges of both sides of the protection plate). . Further, the metal substrate and the metal fins are formed into one body in advance, and the shape of the metal fins may be a lattice shape or the like in addition to a corrugate shape.
