Open type battery module

The utility model discloses an open type battery module which comprises a plurality of battery units which are arranged in parallel, each battery unit is provided with a support and a tray, and the support and the tray are matched to form at least one mounting area; the battery monomers are mounted in the corresponding mounting areas; the first main body part and the second main body part of the battery monomer are attached to form heat conduction connection; a channel communicated with the outside is formed in the peripheral side of the first main body part of the battery monomer, and the channel is positioned in the mounting area. The open type battery module disclosed by the utility model is communicated with the outside through the formed transverse channel and the longitudinal channel, and is in heat conduction connection with the second main body part of the tray, so that heat dissipation can be realized through the tray and the surface of the battery monomer in the battery unit, the heat dissipation ar
