A heat exchanger may include a stacked plurality of plates and a fin plate brazed to each other. Each set of adjacent said plates of the plurality of the plates may define a flow path between plates. Each plurality of the plates may include a flow-through portion penetrating through the plates and through which a fluid is flowable. At least one set of the flow-through portions may be provided at one of the flow paths such that the fluid is flowable from one side of a flow-through portion to an other side of a flow-through portion. The flow-through portion may be disposed outside the fin plate. Each plurality of the plates may further include a through hole disposed outside the fin plate. Each plurality of the plates may further include a first boss portion formed in a substantially elliptical shape surrounding the flow-through portion and the through hole.

Heat exchanger

A heat exchanger is disclosed. The heat exchanger includes a heat exchanger core including a stacked plurality of plates, a top plate, and a bottom plate. The plurality of plates includes two end portion plates, and a plurality of intermediate plates stacked between the end portion plates. Each of the plurality of intermediate plates has a flow-through portion penetrating through the intermediate plates through which a fluid flows. Each of the through holes of each of the plurality of intermediate plates demarcates a flowthrough path which penetrates through the intermediate plate in the stacking direction and is isolated from the flow path between plates. A boss portion having a substantially elliptical shape edge portion is formed at each plate.

A fitting method is for fitting a material to be repaired and a repair patch to be adhesively bonded to the material at adhesive surfaces, each adhesive surface having at least two or more of curved portions. The fitting method includes measuring a shape of the material; measuring a shape of the repair patch; dividing repair patch shape measurement data acquired at measuring the shape of repair patch into pieces of divided data each including one or less of the curved portions; performing, at the adhesive surfaces, fitting processing of the pieces of divided data acquired at dividing the repair patch shape measurement data to material-to-be-repaired shape measurement data acquired at measuring the shape of material; and calculating a gap amount between the material-to-be-repaired shape measurement data and repair patch shape fitting data acquired from the fitting processing at the adhesive surfaces.

Fitting method and repair method

What is disclosed is a heat exchanger including: a core including a plurality of core plates, first and second passages, and a vertical passage; a base plate including a passage port; and a distance plate; wherein the first vertical passage and the passage port are arranged apart from each other in a direction orthogonal to a stacking direction of the core plates, and wherein the distance plate includes a bottom wall part and a swelling part, the bottom wall part being a thin plate-shaped and being joined to an upper surface of the base plate, the swelling part swelling up in the stacking direction from the bottom wall part so as to surround a circumference of a communication passage which communicates the first vertical passage with the passage port and being joined to a lowermost surface of the core in a flange part of a tip of the swelling part.

A core unitof a heat exchanger includes a plurality of core plates that are stacked on one another to alternately constitute oil passagesand cooling water passagesin which oil that is heat-exchanged in the core unitis guided to an outlet portafter passing through a top connecting passageand an oil outlet passage Land in which part of the oil is led from a lower end of an upper/lower oil passage Lis guided to the outlet portthrough an auxiliary passageso that the amount of oil flowing in the oil outlet passage Lis reduced thereby reducing a passage resistance.

An oil cooler has a core portion () formed of stacked core plates (), a bottom plate (), a second bottom plate () and a top plate (), and these are brazed in a furnace. The core plate () has oil communication ports (), cooling water communication ports () and an oil outlet port (). The lower end core plate () has a boss portion () surrounding the cooling water communication port () and a boss portion () surrounding the oil outlet port (). Opening portions () opposite to the boss portions () are formed through the bottom plate (). Therefore, at the time of the brazing, a melted brazing material is not excessively gathered in the boss portion () because the melted brazing material is absorbed in the opening portions ().

A method of detecting light receiving position utilizing optical fibers comprising: a plurality of light receiving surfaces each of which is formed by end surfaces of a plurality of optical fibers arranged straight, and which are arranged in parallel with each other to form rows which are divided into groups to form output ports; light receiving sensors each of which is formed by one light detection device, and which are connected to the corresponding groups, whereby laser beams from the light receiving surfaces are detected by the light receiving sensors through the optical fibers.
