Problems solved by technology

[0002] The existing battery packs generally do not have heat dissipation and heating functions. When the weather is hot, the temperature of the battery pack is high. If the heat is not dissipated in time, the battery pack will be damaged. When the weather is cold, the temperature of the battery pack is low, which may cause the battery group failure

Abstract

The invention discloses a square power battery heat management structure. The square power battery heat management structure comprises first side plates, second side plates, a top plate, a PTC heater and heat dissipation units, the two first side plates are arranged at the front side and the rear side of a battery pack in a mutual parallel manner, the two second side plates are respectively fixedly connected to the left sides and the right sides of the two first side plates through screws, the top plate is fixed to the upper ends of the two first side plates through screws, the PTC heater is fixed to the lower ends of the two first side plates through screws, and the heat dissipation units are fixed to the sidewalls of the first side plates; The sidewall heat dissipation units are used for dissipating heat, the bottom PTC heater is used for heating, the heat dissipation units are started when the temperature is too high, and the bottom PTC heater is started to heat when the structure is in a high-cold region in order to keep the normal use temperature of batteries.

Description

Technical field: [0001] The invention relates to a thermal management structure of a square power battery. Background technique: [0002] The existing battery packs generally do not have heat dissipation and heating functions. When the weather is hot, the temperature of the battery pack is high. If the heat is not dissipated in time, the battery pack will be damaged. When the weather is cold, the temperature of the battery pack is low, which may cause the battery Group failure. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0004] The present invention provides a heat management structure for a square power battery in order to solve the above-mentioned problems in the prior art. [0005] The technical solutions adopted in the present invention include: a thermal management structure of a square power battery, including a first side plate, a second side plate, a top plate, a PTC heater and a he...
