Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] A battery pack with a water-cooled plate, including a battery frame, a water-cooled cover plate 2, and a middle beam 4, all of which are made of aluminum alloy to reduce weight. The battery frame includes a bottom tray 1, the lower surface of the bottom tray 1 has rib partitions 3, the water-cooling cover plate 2 is U-shaped, and the two sides are used to arrange water channels, and the middle beam 4 is fixed in the middle to fix the battery pack. The two ends of the rib partition 3 are against the water-cooling cover plate 2 and the rib partition 3 respectively, forming a water channel in the middle, the water channel is in a circuitous shape, and there are multiple parallel water channel ribs in the water channel.

[0035] There are two ways to connect the bottom tray 1, the water-cooling cover plate and the water channel rib partition...

Abstract

The invention relates to a battery frame tray with a water cooling plate. A water cooling cover plate is welded on the surface of the tray through friction stir welding, a convex rib partition plate is arranged between the water cooling cover plate and the tray, the two ends of the convex rib partition plate respectively prop against the water cooling cover and the tray, a roundabout water channel is isolated between the water cooling cover plate and the tray, the two ends of the water channel are connected with a water inlet nozzle and a water outlet nozzle, a plurality of water channel convex ribs are arranged in the water channel and distributed in parallel, and an intermediate cross beam is fixedly arranged at the middle of the water cooling cover plate and used for positioning a battery pack. The battery frame tray has the advantages that an integrated structure of the water cooling plate and the battery pack has relatively high structural strength and relatively high rigidity, a few parts of the structure are required, and the process step is simplified.

Description

technical field [0001] The invention relates to a battery pack integrated with a water cooling plate. Background technique [0002] New energy vehicles have higher and higher requirements for the lightweight of the whole vehicle, and the lightweight of the body is becoming more and more important for new energy vehicles. Among them, the lightweight of the new energy battery pack occupies a large proportion in the lightweight of the entire vehicle body. The lightweight design of the battery pack mainly includes the lightweight design of the battery and the lightweight design of the battery frame and water-cooled plate. Because new energy vehicles need more breakthroughs and research and development in battery capacity research and development, it is more difficult to lightweight the battery . The lightweight design of the battery frame and water-cooled plate is relatively easy, so the main direction of the lightweight design of the entire battery pack is to reduce the weigh...
