Embodiment Construction

[0043] The present invention will be further described by way of examples below, but the present invention is not limited to the scope of the examples.

[0044] Such as figure 1 Shown is the battery module cooling system provided by the present invention for cooling the battery module 2 located in the battery box 1. The battery module cooling system includes a cooling device 3, a main air duct 4 and a plurality of branch air ducts 5, The cold air outlet of the cooling device 3 is connected to a plurality of branch air ducts 5 through the main air duct 4, and the branch air duct 5 extends to the side of the battery module 2, and the branch air duct 5 faces the battery module 2 with a plurality of 出风孔51。 The vent 51.

[0045] By setting the main air duct 4 and the branch air duct 5, the cold air can be delivered to the designated location to solve the problem of uniform transmission of the cold air, so that the multiple battery modules 2 in the battery box 1 can achieve the same cooli...

Abstract

The invention provides a battery module cooling system and a battery pack. The battery module cooling system is used for cooling battery modules in a battery box and comprises cooling devices, main air ducts and a plurality of branch air ducts; cold air outlets of the cooling devices communicate with the plurality of branch air ducts through corresponding main air ducts; the branch air ducts extend to the side edges of the battery modules; and a plurality of air outlet holes are formed in the surface, facing the battery modules, each branch air duct. According to the battery module cooling system and the battery pack, cold air can be transported to the specified part to solve the problem of uniform transportation of the cold air through arranging the main air ducts and the branch air ducts, so that the plurality of battery modules in the battery box can reach the same cooling effect, the service life of the battery modules is prolonged and the security of the system is improved.

Description

Technical field [0001] The invention relates to a battery module cooling system. [0002] The invention also relates to a battery pack containing the battery module cooling system. Background technique [0003] With the increasing application of new energy technologies, in the field of power batteries and energy storage, lithium battery packs, as a source of energy storage and conversion, are one of the core issues of design. During the operation of the system, the lithium battery module will generate a lot of heat. The internal heat accumulation will increase the battery temperature, increase the battery inconsistency, reduce the battery life, and seriously even cause safety problems. Therefore, the thermal management and heat dissipation inside the battery pack are very critical. [0004] For the heat dissipation of lithium battery packs, air ducts are generally arranged between the modules, and cold air enters between the modules through the air ducts to take away the heat gener...
