摘要： PROBLEM TO BE SOLVED: To make a cooler excellent in assembly property and maintainability in narrow place. SOLUTION: This device is equipped with a heat receiving plate 4, which supports an electric part (5), a cooling medium pipe 8, which circulates a refrigerant in this heat receiving pipe 4, a circulation pump 9 for circulation of the refrigerant provided in the middle of this refrigerant 8, a heat radiation part 10, and a support (2) which supports the heat radiation plate 4 and the said heat radiation part 10. In this case, a displacement absorber (12), which absorbs the displacement of the interval between the heat receiving plate 4 and the heat radiation part 10, is provided in the middle of the cooling pipe 8.

摘要： PROBLEM TO BE SOLVED: To provide a mounting structure for inserting a conductive band bar that has an improved working efficiency and is long without dividing it. SOLUTION: A plurality of conductive band bars are inserted into an enclosure 2 outside the enclosure for tentative assembly, and are clamped and fixed by a conductive band bar clamping tool 8 such as a binding band. The tentatively assembled conductive band bar 1 is inserted into the enclosure 2 through an opening 9 of an enclosure longer direction edge part plate 3 and an opening 10 of the screening plates 4a and 4b of the inside of the enclosure 2. After the insertion, the conductive band bar 1 is holded by a conductive band bar support tool and then is connected to, for example, a control equipment and a terminal block in the enclosure 2.

摘要： PROBLEM TO BE SOLVED: To eliminate a bottom inspection cover system to raise assembly workability of an integral box frame constitution of a control device for a vehicle and improve maintenance inspection efficiency of the integral box frame constitution, by a method wherein the same two long box frames in a box frames constitution are juxtaposed to each other and moreover, the long box frames are arranged on both sides of a car body in combination with each other, and these long box frames are made to mount on a suspension frame duct provided on the upper surfaces of the box frames to form the box frames into an integral box frame constitution. SOLUTION: Two long box frames 9 of the same form are juxtaposed to each other and moreover, the frames 9 are arranged in such a way as to position on both sides of a car body, and a space for enabling the opening and shutting of an inspection cover 6 on the side surfaces of the frames 9 is ensured between the frames 9. Moreover, the frames 9 are made to arrange in consideration of a size requisite to a space for the incorporation work of a high-pressure equipment unit and a built-in equipment unit, such as an equipment for control, as well, the upper surfaces of these two long box frames 9 and a duct 10, which is used in common as a suspension frame, are clamped by a bolt 11 to fix the frames 9 on the duct 10 and the box frames are formed into an integral box frame constitution. As a result, in mounting a housing equipment unit or the like, it becomes possible to incorporate the unit or the like into the box frames from both side surfaces of the box frames, and the assembly workability of the integral box frame constitution of a control device for vehicle use can be reaised.
