Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a power lithium battery heat dissipation mechanism. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. [0003] Power lithium-ion battery refers to a lithium-ion battery with a capacity of more than 3AH. At present, it generally refers to a lithium-ion batt...

Problems solved by technology

[0004] The purpose of the present invention is to provide a power lithium battery heat dissipation mechanism, through the cooperation of the heat sink and the ventilation fan, the inner cavity of the shell can be ventilated, so as to avoid excessive heat in the inner cavity and reduce the service life of the lithium battery body; by setting the water tank, Input cold water into the water tank, connect the first water pump through the first water pipe to input cold water to the cooling water plate for cooling treatment, when the cold water absorbs heat and heats up, the second water pump can be connected to the second water pipe to communicate with the water tank for cold water circulation, and through The electric push rod pushes the lithium battery holder to move up and down. When the lithium battery body is hot, put the lithium battery closer to the heat dissipation water plate, which can quickly cool down and the heat dissipation effect is better; to solve the heat dissipation effect of the ordinary power lithium battery proposed in the above background technology It is not good and it is easy to cause the lithium battery to shake in the inner cavity of the shell when moving
