Embodiment Construction

[0057] The specific embodiments and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0058] like figure 1 As shown, a manufacturing process of a new energy battery box based on extruded profiles includes the following steps:

[0059] Step 1: Extrude the required profile and inspect it. The inspection requires that the profile has no cracks, bubbles, deformation, twisting, no obvious scratches on the surface, no oxidation and other defects, and also requires materials, mechanical properties, dimensions, and harmful substances. And the salt spray test is up to the standard;

[0060] Step 2: Use a sawing machine to saw the profile, and clean it after sawing;

[0061] Use 5% degreaser for cleaning; meet pH 2.0 to 2.5; add degreaser and water to the cleaning pool once a day, and test; every two months, completely replace the pool water;

[0062] the cleaning method:

[0063] 1. First wash the inco...

Abstract

The invention discloses a manufacturing process of a new energy battery box based on an extruded profile. The manufacturing process comprises the steps of extrusion forming, profile sawing, bottom plate welding, overall bottom plate machining and runner milling, runner cleaning, plug block welding, frame assembly and accessory machining, frame, accessory and bottom plate welding, air tightness testing and cleaning, pressure drop testing, final inspection and the like. The liquid cooling system has the remarkable effects that the overall strength and rigidity of the bottom plate of the box body can be ensured under the condition that the liquid cooling performance is met, and the obtained liquid cooling system of the battery box body is good in reliability, bearing capacity, surface flatness and heat exchange effect.

Description

technical field [0001] The invention relates to the technical field of new energy automobile parts processing, in particular to a manufacturing process of a new energy battery box body based on an extruded profile. Background technique [0002] With the rapid development of new energy vehicles, the cruising range has become the focus of users' attention. For new energy vehicles, the most effective way to increase the cruising range is to increase the energy density of the battery pack, that is, to arrange more batteries in a limited space. At the same time, the battery discharges more power during use. In order to maximize the performance of the battery, a liquid cooling system is usually installed inside the battery pack to maintain the battery at a suitable operating temperature. [0003] At present, the main types of battery liquid cooling systems in the new energy vehicle market are as follows: [0004] 1. Harmonica tube type liquid cooling plate [0005] The harmonic...
