摘要： PROBLEM TO BE SOLVED: To thinly form a heat receiving plate without lowering cooling efficiency by a method wherein the mounting part of an electric machine is provided between the heat receiving plate and a refrigerant flow path. SOLUTION: The heat generated on a self-extinguishing type element 12 and a snuffer resistor 13 during operation is transmitted to heat receiving plates 6A and 6B, the heat moves by transmitting to the refrigerant, e.g. water, which is forcedly circulated in the first refrigerant path and the second refrigerant flowing path. The water, which is heated up by absorbing heat, flows as shown by the arrows in the diagram, and it is cooled by radiation from a heat radiating part 11 where heat is exchanged by the outside air. The cooled water is sent out to the refrigerant flow path in the heat-receiving plates 6A and 6B by a circulation pump 10, and the self-extinguishing type element 12 and the snubber resistor 13 are continuously cooled. As the heat-receiving plates 6A and 6B are provided in such a manner that the mounting part of the first and the second refrigerant flow paths and the mounting part of the electric machine are provided separately, the heat-receiving plates 6A and 6B can be formed small in size.

摘要： PROBLEM TO BE SOLVED: To improve cooling efficiency without increasing size, by installing a first cooling means for cooling a heat receiving board, and a second cooling means for cooling the inside of a sealing chamber. SOLUTION: A cooling path is formed in a heat receiving board 6, and a pipe path 10 is so connected with the inlet and the outlet that a closed loop is formed. A circulation pump 11 and a radiator 12 are connected with the middle part of the pipe path 10. The pipe path 10, the circulation pump 11 and the radiator 12 constitute a first cooling means in which water is enclosed. A heat absorbing part 14 equipped with many fins is arranged on the sealing chamber 3 side of a heat pipe 13. On the open chamber 4 side, a radiating part 15 equipped with many fins is arranged. Thus a second cooling means is constituted. The heat generated from a self-extinction type semiconductor element 7 or the like in the sealing chamber 3 is directly or indirectly cooled, so that cooling efficiency is improved. Thereby it can be evaded that the size of an electric apparatus equipment for vehicle is increased.

摘要： PROBLEM TO BE SOLVED: To extend the freedom in equipment arrangement by a method wherein an air blower is arranged so that a heat exchanger may be arranged to absorb cooling air from the side of a heat exchanger arranged on the side wherein the heat exchanger is not arranged to be exhausted from the side wherein the heat exchanger is arranged. SOLUTION: A case body 2 containing an electric converter is hung down below the floor board of a car body 1 by a hanging means so as to leave the space of an air duct 21. Next, an electric part enclosing chamber 5, a main circuit enclosing chamber 3 containing the main circuit of the power converter and a cooling part are contained in the case body 2 from the left side in the track width direction. Next, a radiator 12 as the heat exchanger of the cooling part is arranged on the right side surface of the car body 1 so that an air blower 29 may be arranged to absorb a cooling air 30 from the surface whereon the radiator 2 is not arranged through the intermediary of an air filter to be exhausted from the right side surface whereon the radiator 12 is arranged. Through these procedures, the freedom in the equipment arrangement can be extended even if the package density is increased.

摘要： PROBLEM TO BE SOLVED: To make a power converter a cooling mechanism where the freedom in arrangement of equipment can be raised, even if the density of mounting increase, by fitting out a heat receiving plate, where a switching element is attached and coolant is let pass inside, a heat exchanger for the coolant, a pump for circulating the coolant, a means for blowing cooling air to the heat exchanger, and others, under the floor of an electric motorcar. SOLUTION: Elements being the objects of cooling are attached to both sides of a heat receiving plate 10, and cooling water from a liquid circulation pump 11 is let flow into the heat receiving plate 10, and the cooling water which is heated, receiving the heat, is sent to a radiator, and the temperature of the cooling water is lowered by the cooling air from outside the car. On the other hand, the cooling air 30 being taken in from an air intake 24 opened at the top of a casing 2 to a ventilation port 25 through an air filter 20 installed at a skirt 4 and an air duct 21 is discharged from an air exhaust port 27 to a truck face through a radiator 12, a blower 29, and a cavity 26. This way, the cooling efficiency of the device can be improved, by taking in cooling air 30 from the topside and exhausting air to the bottom side thereby preventing the exhaust air heated by the heat generation of the device from being taken into the casing again.

摘要： PROBLEM TO BE SOLVED: To provide a railway car structure capable of concurrently achieving weight reduction, high rigidity and high strength in a railway car including an engine and a generator.SOLUTION: Louver window sections 24, 24 formed in hollow extruded shape constituting a side structure 20 are comprised of two triangular openings formed by partitioning a rectangular opening along a diagonal line. The diagonal line is extended from an upper corner at the end of the side structure 20 in the longitudinal direction to a lower corner in the central direction, and the corner of the opening is rounded. A louver window reinforcing member 50 is fitted to the end of the opening with a clearance formed therebetween and is joined to a cabin side face board of the side structure 20. In such a structure, a shearing load working on the side structure due to a heavy object such as an engine or a generator is burdened by the reinforcing joined to the hollow extruded shape positioned on the diagonal line and an opening periphery. Thus, even the railway car structure made of aluminum alloy with low rigidity and strength can restrain deformation of an opening formed in the side structure that tends to have concentrated deformation.
摘要翻译：要解决的问题：提供一种能够在包括发动机和发电机的铁路车辆中同时实现减重，高刚性和高强度的铁路车辆结构。形成为构成侧面结构20的中空挤压形状的百叶窗部分24,24由沿对角线分隔矩形开口形成的两个三角形开口构成。斜线从侧面结构体20的端部的长边方向的上方角延伸到中心方向的下角，开口的角部变圆。百叶窗加强件50装在开口的端部，其间形成有间隙，并与侧结构件20的机舱侧面板接合。在这种结构中，由于侧面结构诸如发动机或发电机之类的重物被加在接合到位于对角线上的中空挤压形状的加强件和开口周边上。因此，即使由具有低刚度和强度的铝合金制成的铁路车辆结构也可以抑制侧面结构中形成的倾向于具有集中变形的变形。版权所有（C）2012，JPO＆INPIT
