the utility model provides a high-efficient radiating energy storage module structure, includes door-shaped shell, upper cover plate, front shroud and energy storage module, including door-shaped shell, upper cover plate, front shroud seal the energy storage module, the energy storage module is equipped with heat conduction silica gel pad including the electric core group of parallelly connected equipment between electric core group and the door-shaped shell, makes electric core group and heat conduction silica gel pad closely laminate through the bolt-up between electric core group and the door-shaped shell.
Furthermore, the front end of the electric core group is provided with an aluminum alloy end plate.
Furthermore, the electric core group is fastened with the upper cover plate and the front cover plate through bolts respectively, and the front cover plate is provided with a cooling fan.
Compared with the prior art, the utility model, have following advantage:
the utility model relates to a high-efficient radiating energy storage module structure, structural design is reasonable, adopts the high-efficient heat dissipation of mode of heat-conduction and thermal convection, can provide the high radiating environment of uniformity for every electric core, reduces the difference in temperature between the electric core, ensures the security performance and the life of module product.
Drawings
Fig. 1 is an explosion diagram of the energy storage module structure with high heat dissipation efficiency of the present invention.
Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, an energy storage module structure with high heat dissipation efficiency comprises a box body formed by a door-shaped shell 1, an upper cover plate 2, a front cover plate 3 and an energy storage module, wherein the door-shaped shell 1, the upper cover plate 2 and the front cover plate 3 adopt sheet metal structural members and seal the energy storage module, so that the module reaches the IP20 protection level. The energy storage module comprises an electric core group 4 assembled in parallel, and the parallel assembly refers to that a flexible heat conduction silica gel pad is added between the electric cores and matched with proper mechanical pressure to enable the electric cores to be completely and tightly attached without air residue; the battery cells are respectively cooled in the cooling process, the consistency of the cooling environment is ensured, heat cannot be continuously accumulated from front to back like series connection, and moreover, the heat conductivity coefficient of the heat-conducting silica gel pad is far higher than that of air, so that the temperature rise of the battery cells can be effectively reduced; the suitable mechanical pressure that adopts means that design relevant mechanical frock and suitable pretightning force compress the heat conduction silica gel pad between the electricity core and between the electricity core to cooperation billet is spacing fixed, then releases mechanical pretightning force and makes the heat conduction silica gel pad between the electricity core and between the electricity core be in suitable compressed state always, stops outside air's packing. Specifically, the electric core group 4 and the door-shaped shell 1 are tightly connected through bolts so that the heat-conducting silica gel pad is tightly attached to the electric core group 4. Furthermore, the front end of the electric core group 4 is provided with an aluminum alloy end plate 5; because the coefficient of heat conductivity of aluminium is very high, according to the heat-conduction law, the heat is conducted outside the module by aluminum alloy end plate 5 on by the inside aluminum alloy end plate 5 that shifts of electric core again to reduce the inside temperature of module. The electric core group 4 is respectively fastened and connected with the door-shaped shell 1, the upper cover plate 2 and the front cover plate 3 through bolts. Be equipped with radiator fan 6 on the front shroud 3, 5 front sides of aluminum alloy end plate are located to front shroud 3, and radiator fan 6 circulates the inside air fast through the thermal convection mode of blowing and suitable wind channel design, and the box outside is in time discharged to the air that inside temperature is high, and the air that outside temperature is low in time sinks into.
Preferably, the bottom of the electric core group 4 is provided with a heat-conducting silica gel pad, the heat-conducting silica gel pad is compressed properly and is filled in the gap at the bottom of the electric core group 4 through the fastening action of the high-strength bolt, so that the heat dissipation effect of the electric core is further improved, the heat conductivity coefficient is increased, and the contact thermal resistance is reduced.
