[0031] A battery installation cabinet for a new energy electric ship provided by the present utility model mainly involves aspects such as the installation, fixation, heat dissipation, and maintenance of the battery. Specifically as follows:

[0032] 1. Battery installation and fixation:

[0033] The battery installation cabinet adopts a design of two sets of upper and lower battery support plates 7, and each set of support plates consists of an upper and a lower plate. A plurality of raised portions 8 are equidistantly provided on the top surface of the upper plate and the bottom surface of the lower plate.

An "S"-shaped air flow channel is formed inside the refrigeration box 12. A coolant coil 121 is arranged in the "S"-shaped flow channel of the refrigeration box 12. The coolant enters the coolant coil 121 through a coolant inlet pipe 122, circulates inside the coolant coil 121, absorbs heat and then is discharged through a coolant outlet pipe 123. External air enters the refrigeration box 12 from an air inlet pipe 13, is cooled by the coolant coil 121 and then is discharged from an air outlet pipe 14, and then is sent into the battery cabinet 1 through a cold air duct 15 and a cold air branch pipe 16, thereby cooling the battery.

[0038] The cooled air is evenly distributed through a plurality of mesh plates 17 at different heights on the back surface of the battery cabinet 1 and is guided to the battery surface through a mesh plate cover plate 18, improving the heat dissipation efficiency.
