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： 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： A device for utilizing waste heat from a heat engine comprises a Rankine cycle including a pump, a heating device, an expansion device, and a condenser device, and a controller for controlling an operation of the Rankine cycle. The controller calculates an optimum heat collection amount (Qho) as a heat value to be collected from waste heat of the engine, wherein the heat collection amount (Qho) is calculated as an optimum amount in relation to a potential maximum heat radiation amount (Qco) to be radiated at the condenser device. The controller calculates an optimum flow amount (G) of refrigerant corresponding to the optimum heat collection amount (Qho), so that a maximum driving power (L) is generated at the expansion device.
