Problems solved by technology

As a method of temporarily fixing, there is known a method of welding the outer peripheral part of the laminated body and using a dedicated fixing jig. However, in the case of welding the outer peripheral part, the manufacturing process is very complicated, and there are residues in the finished product. Problems such as welding traces, and in the case of using dedicated fixing jigs, there is a problem of increased costs corresponding to it

Embodiment Construction

[0034] figure 1 In the first embodiment of the plate-stacked heat exchanger, each member is shown as an exploded perspective view when temporarily fixed. The heat exchanger 1 has a fully laminated structure, and includes a top plate 2, a bottom plate 3, and a plurality of inner plates 4 serving as heat exchanging parts.

[0035] The material of each plate is metal such as aluminum (including alloy) and stainless steel, and may be a non-scaling material or a coating material in which the surface of the base material is covered with solder. In addition, in the case of a non-scaling material, solder was applied and used to a joint part.

[0036] Each plate is formed in a square shape (specifically, a rectangle) in plan view. The top plate 2 has fluid inlet pipes 5 and fluid outlet pipes 6 for cooling water or the like, and bolt holes 7 for fixing the heat exchanger 1 to, for example, an object to be fixed are provided at four corners of the top plate 2 . Bolt holes 8 and 9 are...

Abstract

Provided is a stacked plate heat exchanger having a structure that can be provisionally fixed by a simple structure during brazing, without using separate expensive parts. A stacked plate heat exchanger comprising a top plate (2), a bottom plate (3), and a plurality of inner plates (4), said heat exchanger characterized in that an upwardly bent tab part (10) is formed on at least one of said plates, a cutout part (11) is formed in plates other than the plate on which the tab part (10) is formed, and the plates are stacked and fixed to one another with the tab part (10) and the cutout part (11)in a fitted state.

Description

technical field [0001] The present invention relates to a plate-stacked heat exchanger that can be used in coolers or the like for cooling electronic devices such as inverters. Background technique [0002] Conventionally, as a plate-stacked heat exchanger (solid cooler) that can be used in coolers of electronic equipment such as inverters, it is known that inner plates having flow passages are stacked to form a plate-shaped heat exchanger. The top plate and cup-shaped bottom plate surround the inner plate in a cup-plate structure, and the flat-shaped top plate and bottom plate sandwich the inner plate in a fully laminated structure. [0003] These plate-stacked heat exchangers are generally produced by integrally brazing the entire heat exchanger, but during brazing, it is necessary to laminate and temporarily fix inner plates, cup plates, etc. in a positioned state. As a method of temporarily fixing, there is known a method of welding the outer peripheral part of the lami...
