Abstract

The invention discloses a heat dissipation device of a lithium ion battery, which includes a box, the two sides of the top of the box body are provided with deep grooves, the inner cavity of the deepgroove is provided with a condensing tube, the two sides of the inner cavity of the box are provided with mounting grooves, the inner cavity of the mounting groove is fixedly connected with a heat dissipating copper plate through bolts, the bottom of the right side of the cabinet is fixedly connected with a support plate, the top of the support plate is fixedly connected with a condensate tank, the top of the condensate tank is communicated with a hose, and one end of the hose away from the top of the condensate tank is communicated with the top end of the condensate tube. In accordance with the present invention, the box, the groovedeep grooves, the condensing pipes, mounting grooves, the cooling copper plates, the support plates, the condensate tank, hoses, pumps, partitions, through holes, support blocks, motors, fan blades and ventilation holes can be used together to dissipate heat generated by lithium ion batteries efficiently and quickly, so that temperature rise is prevented, deformation is prevented, the probability of fire blast is reduced and the safety of use of a lithium ion battery is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a heat dissipation device for lithium ion batteries. Background technique [0002] Lithium-ion battery is a kind of secondary battery. It mainly relies on lithium ions to move between the positive electrode and the negative electrode. During charging and discharging, lithium ions intercalate and deintercalate between the two electrodes: It is deintercalated from the positive electrode and inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true when discharging. Lithium-ion batteries are widely used due to their high energy density. When lithium-ion batteries are used, a large amount of heat will be generated. However, the existing The heat dissipation device has poor ventilation and heat dissipation conditions, and the battery is easy to heat up, bulge and deform, which directly consti...
