Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a mounting device for a laminated heat exchanger used, for example, in oil coolers for motorcycles, general automobiles, and industrial machinery.

Conventional technology Conventionally, the mounting bracket for an aluminum laminated heat exchanger used as an oil cooler is
It was brazed together with the core part of the heat exchanger, but
This had the following problems.

() Thick-walled aluminum materials were often used for mounting brackets, resulting in high material costs.

() Processing had to be performed to position the bracket at the bracket attachment point in the core of the heat exchanger, which increased the production cost of the mold for manufacturing the plates that make up the core.

() The materials used for the bracket were limited because it was brazed to the core.

() The strength of the bracket decreased due to changes in heat quality during brazing.

() During the so-called setting process before bulk brazing of the heat exchanger, the use of brackets required more man-hours for assembly, and a bracket holding jig was required.

() Since the mounting bracket is set so as to protrude outward from the core part, the bracket becomes clumsy, resulting in poor loading efficiency of the heat exchanger assembly in the furnace during bulk brazing, and heat Manufacturing of exchangers is inefficient and productivity is low.

Purpose of the invention The purpose of this invention is to solve the problems of the prior art described above, and to reduce the thickness of the bracket components by attaching the components of the heat exchanger mounting bracket to the core part of the heat exchanger after brazing. In addition, there are no restrictions on the materials used, and it is also possible to use materials different from the core part, making it possible to increase the strength of the bracket components, reduce material costs, and reduce the cost of the bracket. Since the component parts are not brazed together with the core part of the heat exchanger, the production cost of the mold for the plate that makes up the core part is reduced, and there is no need for the conventional bracket holding jig, and The number of man-hours required for assembling the brackets can be reduced, and there is no reduction in the strength of the bracket components due to brazing.Furthermore, since only the core of the heat exchanger is manufactured by brazing all at once, there is no need to use a furnace during brazing. It is possible to efficiently manufacture only the core part of a general-purpose heat exchanger, which improves the loading efficiency of the core part assembly inside the machine, and improves productivity. An object of the present invention is to provide a mounting device for a laminated heat exchanger that can significantly reduce manufacturing costs.

Structure of the Device In order to achieve the above-mentioned object, this device consists of a plurality of intermediate plates each having a recess for forming a fluid flow path and a recess for forming a header on one side, which are stacked on top of each other in a layered manner. Side plates each having a recess for forming a fluid flow path on one side are stacked on both ends in the stacking direction, thereby forming parallel flat tube portions and a pair of header portions communicating with each flat tube. A plate-shaped first clamping member having a first plate clamping part and a mounting part to be coupled to the vehicle body etc. is provided at a required location on the peripheral edge of the laminated heat exchanger, and a plate is attached to the first plate clamping part. A laminated heat exchanger to which a fixture is fixed, which includes a second clamping member having a second plate clamping portion facing each other via a second clamping member, and a connecting member that connects both clamping members with a plate sandwiched therebetween.
