Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The radiator structure of of the present utility model a kind of Vehicular battery bag as Figure 1-4, comprise power brick 1, simple for mounting structure and mounting process, and power brick 1 is arranged on platform floor 2.Due to the casing of power brick for sealing, battery operated middle can the heat radiation, heat comes out by the metal tank wall of power brick, and therefore the arrangement space for power brick has certain heat radiation requirement.
The radiator structure of Vehicular battery bag of the present utility model is designed to semi-enclosed radiator structure on arrangement space, the cyclic space of circulation of air before and after forming, be beneficial to the heat radiation of power brick, specifically in the power brick left and right sides, design left shrouding 3 and right shrouding 4, power brick space and space outerpace are separated, power brick is positioned at by platform floor 2, left shrouding 3, right shrouding 4, in semi-enclosed cyclic space that load floor 5 and front shrouding 6 surround, the front end of this cyclic space and the left and right sides are enclosed construction, wherein, left shrouding and right shrouding belong to symmetrical member, become the height shape, distance between left and right shrouding meets the installation requirements of power brick, also should leave certain gap between the left and right tank wall sidewall of left and right shrouding and power brick simultaneously, forms left side gas channel 7 and right side gas channel 8.
But certain ventilation gap is arranged between power brick and load floor, form top stream passage 9.Platform floor is designed to prominent muscle form, with the platy structure of prominent muscle 10; Platform floor is not only strengthened the Rigidity and strength of base plate, forms the bottom gas channel 11 of circulation of air between the rough base plate face that prominent muscle 10 forms simultaneously and the bottom surface of power brick, is beneficial to the circulation of air of power brick installing space.
