摘要： A heat exchanger has a core portion composed of several pairs of first and second plates laminated with and brazed to one another. Each of the first and second plates is composed a core member, a brazing filler layer formed on a surface of the core member, and a sacrifice layer formed on the other surface of the core member. For instance, to form a pair of the first and second plates, the first plate is formed with a convex portion with an opening portion, and a burring portion of the second plate is inserted into the opening portion and is plastically deformed such that the sacrifice layer of the second plate closely contacts the brazing filler metal layer of the first plate. Then the first and the second plates are brazed together.

摘要： An oil cooler is fixed to an engine via an installation stay provided around an outer periphery of the oil cooler. Thus, the load applied to a core portion is reduced, and the load is dispersed on entire portion of the oil cooler. Thus, the respective stresses applied to respective portions of the oil cooler are very small, and a deformation of the core portion is prevented. Furthermore, since the respective stresses on any portion of the oil cooler is reduced, it is possible to make the oil cooler with aluminum whose strength is lower than that of iron. Furthermore, since the thickness of the installation stay can be reduced, difference in the thermal expansion quantity caused by difference in coefficients of linear expansion of the bolt and the installation stay is significantly reduced, and the loose bolt of the bolt caused by difference in coefficients of linear expansion is prevented.

摘要翻译： 油冷却器通过设置在油冷却器外周周围的安装支柱固定在发动机上。 因此，施加到芯部的负荷减小，负荷分散在油冷却器的整个部分。 因此，施加到油冷却器的各个部分的各个应力非常小，并且防止了芯部的变形。 此外，由于油冷却器的任何部分上的各应力减小，因此可以使强度低于铁的铝制成油冷却器。 此外，由于可以减小安装支柱的厚度，所以由于螺栓的线性膨胀系数的差异和安装支架的差异导致的热膨胀量的差异显着降低，螺栓的松动螺栓由系数差 线性膨胀被阻止。

摘要： An assembly (oil cooler unit), under the state where first and second plates (130, 140) prevent a heat exchange core (110) from falling from a casing (120), is provisionally assembled, and this oil cooler unit is dipped in a flux to apply the flux. A seal surface plate (150) is then assembled to the second plate (140) and is brazed by heat-brazing in an inert gas atmosphere. Since a flux residue on the seal surface plate (150) can be drastically reduced in this manner after brazing is complete, the seal surface plate (150) can secure predetermined surface texture even after brazing is complete while the number of process steps necessary for applying the flux is reduced.

摘要： Oil passages 113 through which oil passes are formed with plates 111, 112 composed of aluminum or an aluminum alloy in an oil cooler, according to the present invention, that is a heat exchanger with an extended life. Moreover, fins 123a composed of a material having a corrosion potential more negative than those of the plates 111, 112 are arranged in cooling water passages 123 through which cooling water, for exchanging heat with oil, passes. A sacrificial corrosive layer 301 having a corrosion potential more negative those of the plates 111, 112 and the fins 123a is formed on each of the surfaces on the sides of the cooling water passages 123 of the plates 111, 112. As a result, the sacrificial corrosive layer 301 is preferentially corroded, and not only the plates 111, 112 but also the fins 123a can be protected. Consequently, the pressure-proof strength of the oil cooler can be maintained, and the product life can be improved.

摘要： The stacked plate oil cooler has a first plate and a second plate. Both the first plate and the second plate are made of a three-layered aluminum alloy clad sheet. The second plate is folded at an outer rim to place the brazing material layer on both sides of the second plate. The first and second plates and are stacked alternately and brazed to define a water passage between sacrificial layers and, and to define an oil passage between brazing material layers. The first plate is folded at an outer rim to place the sacrificial layer on a lateral outside of a core assembly to decrease exposure of the brazing material layer to the lateral outside.

摘要： The present invention relates to a fan having a plurality of equiangularly spaced, radially extending blades. The spacing provided between adjacent blades is substantially constant along the entire radial length of the blade for increasing a blowing efficiency, while also allowing a mold separation operation along the axial direction during the formation of the fan using a mold. In a case where the blade is a sweep-forward blade, the number of the blades is seven or more and has a sweep-forward angle of the blades between 35 to 45 degrees. Finally, in case where an electric motor for rotating the fan is supported by stays, the number of stay member and the number of blades, which are not evenly dividable by each other, should satisfy a relationship of 2,000

摘要： An axial flow fan device capable of reducing the stagnant flow at the root area of blades. These blades 18 are arranged so that they extend radially from a boss portion 14 so that they are circumferentially spaced along the circumference of the boss portion 14. Each of the blades 18 has an arc shaped cross section having a bending ratio value .alpha., that is a ratio of the bending height h of the arc shape to the length l of the chord of the arc shape. The value of the bending ratio rapidly increases from the middle portion of the blade to the root portion. The value of the bending ratio at the root portion is about 12%.

摘要： A heat exchanger made of aluminum includes a plurality of first plates and a plurality of second plates stacked alternately in the direction along the thickness thereof. The first plates and the second plates each constitute a three-layer structure. A first sacrificing material layer is clad on the side surface of a first core member making up each of the first plates nearer to a cooling water path and a second sacrificing material layer is clad on the side surface of a second core member making up each of the second plates nearer to the cooling water path. A first brazing material layer is clad on the side surface of the first core member nearer to an oil path, and a second brazing material layer is clad on the side surface of the second core member nearer to the oil path. The outer peripheral portions of the first and second plates are bent substantially into a U shape in such a manner that the first brazing material layer is interposed between the outer peripheral edge portions of the first and second plates and the adjacent second and first plates, respectively.
