Embodiment 1

[0053] Such as Figure 1-7 As shown, the present embodiment provides a stack box, the stack box is an aluminum alloy stack box, which includes a bottom plate 1, and two pairs of side plates facing each other, a front plate 2 and a rear plate 5, The left side plate 3 and the right side plate 4, the above-mentioned side plates and bottom plates are all aluminum alloy plate bodies, the advantages of aluminum alloy are light weight, high strength, and easy to process; wherein, the bottom plate is a rectangular plate arranged horizontally, and each side plate is respectively Vertically arranged rectangular boards; preferably, each pair of side boards has a first step structure on both side edges, that is, respectively includes a first step structure 2b of the front board, a first step structure 3a of the left side board, and a first step structure 3a of the right side board. The first stepped structure 4a of the side plate and the first stepped structure 5a of the rear plate; the t...

Embodiment 2

[0075] This embodiment provides an aluminum alloy stack box, which differs from the stack box provided in Example 1 in that only the two side edges of the pair of side plates have a first stepped structure, and the two sides of the two pairs of side plates have a first stepped structure. The side edges are clamped to each other, specifically, the pair of side plates that do not have the first step structure on the edge are clamped into the first step structure embedded in the two side edges of the other pair of side plates, and there is a weld at the joint; The bottom edges of the two pairs of side plates all have a second step structure, and the second step structure is respectively clamped on the edge of the bottom plate, and there is a weld at the joint; it can be understood that the edge does not have the first step structure. The bottom edge of the pair of side plates is the same as the length of the first step structure snapped into the two side edges of the other pair of...

Abstract

The invention relates to the field of galvanic pile box bodies, in particular to a galvanic pile box body and a manufacturing method thereof. According to the galvanic pile box body, first step structures are arranged in the edges of the two sides of at least one pair of side plates in two pairs of opposite side plates, the edges of the two sides of the two pairs of side plates are clamped with each other, and welding seams are formed in the clamping positions; second step structures are arranged on the edges of the bottoms of the side plates, the second step structures are clamped to the edges of the bottom plate respectively, and weld joints are arranged at the clamping positions; according to thegalvanic pile box body, the edges of the side plates and the bottoms of the side plates areconnected with the edge of the bottom plate through the welding seams, so that the defects of screw looseness, thread corrosion, sealant aging and large screw mounting space requirement are overcome;and moreover, in the forming process of the electric pile box body, the bottom plate, the front plate, the left side plate, the right side plate and the rear plate are clamped with one another to replace an inner support frame, so that the defects of troublesome disassembly and assembly, low efficiency and high cost of the inner support frame are overcome.

Description

technical field [0001] The invention relates to the field of stack boxes, in particular to a stack box and a manufacturing method thereof. Background technique [0002] The fuel cell stack is composed of multiple single cells stacked in series, with seals embedded between several cells, pressed by the front and rear end plates, and then fastened with screws to form a fuel cell stack. At present, most of the existing stack boxes use bolts to connect the front, rear, left, and right side plates and bottom plates, and process threaded holes on the sides of the front, rear, left, and right plates, and process countersunk holes on the outer surfaces of the front, rear, left, and right bottom plates. , The assembly screw realizes the assembly connection of the box body, and the assembly gap is filled with sealant to ensure the airtightness of the box body. [0003] However, the stack box connected by screw assembly has the following defects: [0004] 1. It is connected by screws...
