Example Embodiment

[0031] Example 1

[0032] The top plan layout of a large-rate battery liquid cooling system is as figure 1 As shown, the system includes a battery 4, a module frame 6, a liquid cooling wall 9 and other components. The battery 4 is placed in the module frame 6. The module frame 6 is placed in a space surrounded by the liquid cooling wall 9, the enclosure 1, and the liquid collecting plate 5. The module racks 6 are arranged in four rows, each row has three module racks 6, and a total of 12 module racks 6 are placed in the entire liquid cooling system. Each row of module frames 6 is separated by a liquid-cooled wall 9. From figure 1 It can be seen that both sides of each module frame 6 are liquid-cooled walls 9.

[0033] Such as figure 1 , Image 6 Shown: the inside of the liquid cooling wall 9 is provided with a rectangular liquid cooling tube 15, part of the wall surface of the rectangular liquid cooling tube 15 protrudes from the wall surface of the liquid cooling wall 9, formi...

Example Embodiment

[0044] Example 2

[0045] The difference between this embodiment and the first embodiment is: a small liquid cooling plate 16 is installed on the module frame 6, see Figure 5 , Alternative to the T-shaped heat conducting plate in Example 1. One side of the liquid cooling plate 16 is in contact with the battery 4 in the module frame 6. The liquid-cooling plate 16 is provided with liquid-cooling pipes, and the liquid-cooling pipes in the liquid-cooling plate can be connected with the liquid-cooling pipes in the liquid-cooling wall through the hose 17 and the joint 18, as long as the corresponding positions on the liquid-cooling wall 9 are opened A good connection is enough. In this way, the liquid refrigerant in the liquid cooling wall 9 can flow through the liquid cooling plate 16 and part of the heat on the battery 4 can be taken away.

[0046] In this example, the liquid cooling wall 9 does not need to be slotted, which can make the arrangement of the liquid cooling pipes in the...

Abstract

The invention provides a high-ratio power battery liquid-cooling system. The high-ratio power battery liquid-cooling system comprises batteries, module carriers and liquid cooling walls, and is characterized in that the module carriers are arranged side by side, the rows of module carriers are separated from one another through the liquid cooling walls, rectangular liquid cooling pipes are arranged inside each liquid cooling wall, the wall face of each rectangular liquid cooling pipe partially protrudes out of the wall face of the corresponding liquid cooling wall and can be in contact with the corresponding battery through an opening on one side of the corresponding module carrier, and a convex heat conduction plate is installed on the other side of one module carrier and can be inserted into a groove of one liquid cooling wall to be in contact with the liquid cooling wall. By the high-ratio power battery liquid-cooling system, a multi-surface liquid-cooling scheme can be provided for a high-ratio charge-discharge battery system, the service life of the battery can be prolonged, and the traveling distance of an electric vehicle increases.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a liquid cooling system for a battery box of an electric vehicle. Background technique [0002] With the improvement of human's requirements for environmental protection, the research and application of electric vehicles have attracted more and more attention. Since the current single battery cannot meet the power requirements of electric vehicles, the power of electric vehicles is provided by a battery box with multiple batteries. In order to ensure that electric vehicles can work safely and normally in various environments, the battery box usually needs to have a cooling system. Liquid cooling is a common technical solution in high temperature environments. Its purpose is to provide efficient cooling for the cells and enable each cell to operate in a near-uniform environment. A common solution is to place the battery on a horizontal liquid cooling plate, which is in contact ...
