All side beam parts 47 and 59 of rear curb girder parts are by elongated rectangular flat shape material being carried out bending process at 1 position, making the shape of the section that is cut off by the plane with the length direction quadrature become " L " font.
49 of the 3rd frame partss are by elongated rectangular flat shape material being carried out bending process at 2 positions, making the shape of the section that is cut off by the plane with the length direction quadrature become " コ " font.On the 3rd frame parts 49, the pars intermedia of its length direction is bent about 90 °, forms thus fore-and-aft direction extending part 93 and horizontal expansion position 95, forms " L " font (with reference to Figure 14, Figure 15 etc.).
And be following state in the bending that the length direction pars intermedia carries out: take along the axle of the Width of base plate 51 (with the direction of the thickness direction quadrature of the length direction of the 3rd frame parts 49 of linearity before the bending and base plate 51) extension as center of turn, the bottom surface of the thickness direction of base plate 51 (with the face that has pair of side plates section 53 to hold up be the face of opposition side) intersecting angle be (reflex angle) 270 °, and the intersecting angle of top (the having pair of side plates section 53 to hold up the face of side) of the thickness direction of base plate 51 is (bad angle) 90 °.Thus, the 1 place bending by carrying out at the length direction pars intermedia can realize the plastic deformation as side plate 53 shrinks.
In addition, the end at the horizontal expansion position 95 of the 3rd frame parts 49 engages with the 2nd frame parts 29, and the end of fore-and-aft direction extending part 93 is holded up section 81 with the above-below direction of fixed parts 33 and contacted.And when being arranged at freight container 202 on framework 5 cooling mechanism, side plate 53 is positioned at the rear of base plate 51 or the center side (central side, inboard) of left and right directions (laterally).
The longitudinal framing parts 55 of central authorities are by elongated rectangular flat shape material being carried out bending process at 2 positions, making the shape of the section that is cut off by the plane with the length direction quadrature become " コ " font.About 57 of longitudinal framing parts be by elongated rectangular flat shape material is carried out bending process at 1 position, make the shape of the section that is cut off by the plane with the length direction quadrature become " L " font.
In addition, when the cooling mechanism of being located on the freight container 202 is provided with framework 5 under the state of fan support unit 21, fan support unit 21 engages with beam parts 47 and lateral frame element 25 by bolt and gives prominence to the place ahead of framework 5 to cooling mechanism.And the front end at fan support unit 21 is provided with fan 19.
Shell 2 is subjected to the supporting of outer casing supporting body 101, and this outer casing supporting body 101 is located at cooling mechanism integratedly with on the framework 5 by welding manner or bolt.
Although only show the condenser cover 61 on right side among Fig. 4, the left side also is provided with condenser cover etc.Equally, the right side also is provided with fan support unit 21 etc.
Cooling mechanism with frame parts 5 be by closed section component parts 31 make and lateral frame element 25 on the 1st frame parts 27 or the junction surface part between the 2nd frame parts 29 form the closed section structure, although therefore weight ratio structure in the past is lighter, but the rigidity of lateral frame element 25 is higher than structure in the past, thereby has improved the rigidity of cooling mechanism with framework 5.
Namely, the weight of fan 19 or condenser 17 is mainly supported by lateral frame element 25, and the both ends of this lateral frame element 25 are supported by the 1st frame parts 27 and the 2nd frame parts 29, therefore the reticulation part that framework 220 that need not be in the past is such makes cooling mechanism with the designs simplification of framework 5 and realizes lightweight.Reduce thus cooling mechanism with the assembling procedure of framework 5 and prevented assembly precision decline.
In addition, owing to having formed frame-shaped construction with lateral frame element 25, the 1st frame parts 27 and the 2nd frame parts 29, when the moment of rupture that therefore produces when the weight by fan 19 or condenser 17 is applied on the lateral frame element 25, will produce larger moment of rupture at the both ends of lateral frame element 25.But, because on lateral frame element 25 and the junction surface part of 29 of the 1st frame parts 27 or the 2nd frame partss be the closed section structure, make on the lateral frame element 25 to produce heavily stressed position and obtained enhancing, be enough to bear the larger moment of rupture that produces at the both ends of lateral frame element 25.
In addition, when adopting cooling mechanism with framework 5, because the end (end that is connected with lateral frame element 25) of the 1st frame parts 27 or the 2nd frame parts 29 has the form of using with the plane cut-out of the length direction quadrature of the 1st frame parts 27 or the 2nd frame parts 29, so lateral frame element 25 easily engages with the 1st frame parts 27 or the 2nd frame parts 29 exactly.
In addition, because the end (end that is connected with lateral frame element 25) to the 1st frame parts 27 or the 2nd frame parts 29 needs only point-blank cut-out, therefore need not use special instrument, anchor clamps or device, easily carry out the end processing of the 1st frame parts 27 or the 2nd frame parts 29.
Again because the end of the 1st frame parts 27 or the 2nd frame parts 29 is not the special shape such as circular-arc, but linearity (plane), therefore add man-hour in the end to the 1st frame parts 27 or the 2nd frame parts 29, the material (fragment) that must discard can be produced hardly, the waste of material can be avoided.
In addition, when adopting cooling mechanism with framework 5, because 25 of lateral frame element arrange 1, therefore can make cooling mechanism further realize lightweight with framework 5.
And, when adopting cooling mechanism with framework 5, about arrange a pair of the 1st frame parts 27 and about a pair of the 2nd frame parts 29 be set support lateral frame element 25, although therefore alleviated weight, improved bending rigidity and the torsion rigidity of lateral frame element 25.
In addition, with on the framework 5, identical shaped by each frame parts 25,27,29 section form are made at cooling mechanism, make each frame parts 25,27,29 material can be general, can improve the economy when producing in enormous quantities.
In addition, when adopting cooling mechanism with framework 5, the rigidity of beam parts 47 is lower than the rigidity of lateral frame element 25, so the lower beam parts 47 of rigidity just correspondingly make cooling mechanism alleviate weight with framework 5.
In addition, when adopting cooling mechanism with framework 5, the 1st frame parts 27 and the 2nd frame parts 29 are located on the freight container 202 by fixed parts 33, so the 1st frame parts 27 and the shape of the 2nd frame parts 29 or the shape simplification of fixed parts 33, easily cooling mechanism is arranged on the freight container 202 with framework 5, and can further alleviate cooling mechanism with the weight of framework 5, cut down number of parts, shorten and make man-hour.
In addition, cooling mechanism by metal plate is consisted of frame parts do bending process, therefore can select to meet thickness and the shape of the metal plate that rigidity requires with framework 5, and comparing with the frame parts that consists of with shaped steel can expendable weight.
In addition, when adopting Vehicular cooler 1, in cooling mechanism framework 5 sides (freight container 202 sides) supports fans 19, therefore come the occasion of supports fans to compare with supporting mass with condenser side, can make that forwards the weight ratio of the parts of outstanding (overhanging) is in the past lighter with framework 5 from cooling mechanism, make that to be applied to cooling mechanism less than in the past with the moment of rupture value on the framework 5.And the moment of rupture value reduces just correspondingly to have alleviated the weight of cooling mechanism with framework 5.
Namely, as shown in figure 26, be positioned at cooling mechanism is to support with carriage not shown in the figures (being arranged at integratedly cooling mechanism with the carriage on the framework 220, condenser supporting mass with the place ahead of framework 220 at cooling mechanism) with the condenser 17 in framework 220 the place aheads in the past, and comes supports fans 19 with above-mentioned carriage.
But, this example is then shown in Fig. 2 waits, not by the condenser supporting mass, but come supports fans 19 by being arranged on integratedly cooling mechanism at cooling mechanism with the place ahead of framework 5 with the fan support unit 21 on the framework 5, therefore be applied to cooling mechanism less than in the past with the moment of rupture value on the framework 5.
In addition, in the process of the total weight of determining cold insulation car 200, owing to having used lightweight cooling mechanism with framework 5 Vehicular cooler 1 to be arranged on the cold insulation car 200, therefore can increase the Container Loading weight of cold insulation car 200.In addition, owing to having alleviated the weight of cold insulation car 200, therefore can make cold insulation car 200 save the energy.
And the cooling mechanism of this example is 17kg with the quality of framework 5.And if cooling mechanism in the past shown in Figure 25 will obtain with the cooling mechanism of the present embodiment just needing the quality of 30.4kg with the identical rigidity of framework 5 with framework 220.As seen the cooling mechanism of this example can be than alleviated approximately 40% weight in the past with framework 5.
