【Specific implementation mode】

It is clear in order to make the purpose of this utility model, technical solution and advantageous effects be more clear, below in conjunction with attached Figure and specific implementation mode, the present invention will be further described in detail.It should be understood that described in this specification Specific implementation mode is not intended to limit the utility model just for the sake of explaining the utility model.

Referring to Fig. 1, the utility model provides a kind of battery case radiator 100, including battery case 10, it is set to battery Battery modules 20, radiator 30 in case 10 and heat radiator 40.

In a rectangular parallelepiped shape, the battery case 10 includes 11, two parallel opposite end walls of a bottom wall to the battery case 10 12, the two side walls 13 and roof (not shown) of two end walls 12 are connected.In this described mode, offered on an end wall 12 One installation gap 121.The installation gap 121 is rectangular.

The battery modules 20 are set in the battery case 10, the battery modules 20 in a rectangular parallelepiped shape, the battery One end of module 20 is equipped with radiator 30.The radiator 30 and an end wall 12 for offering the installation gap 121 Interval is opposite.In the present embodiment, the radiator 30 is radiator fan.The radiator 30 is by the battery modules Thermal current blowout in 20.

It please refers to Fig.1 and Fig. 2, the heat radiator 40 is installed in the installation gap 121 and is filled with the heat dissipation It is opposite to set 30 intervals.Specifically, the heat radiator 40 includes a main part 41, multiple first radiating fins 42 and multiple Second radiating fin 43.41 rectangular plate of the main part, the main part 41 are resisted against on the end wall 12 and seal institute State installation gap 121.The length of the main part 41 is more than the length of the installation gap 121, the width of the main part 41 More than the width of the installation gap 121.Further, the main part 41 and the end wall for offering the installation gap 121 It is equipped with waterproof gasket cement 411 at 12 abutting, can prevent external moisture from entering in battery case 10.

Multiple first radiating fins 42 and multiple second radiating fins 43 are connected to two opposite faces of the main part 41 On.Multiple first radiating fins 42 are spaced evenly distributed and are vertically connected on the main part 41, multiple first radiating fins 42 are located in the battery case 10 and are spaced relatively with the radiator 30 in the battery modules 20.Multiple second radiating fins 43 intervals are evenly distributed and are vertically connected in the one side opposite with multiple first radiating fins 42 of the main part 41, Duo Ge Two radiating fins 43 are set to across the installation gap 121 outside the battery case 10.

The heat radiator 40 is made of graphite, has high-termal conductivity, 700~1300w/ of thermal coefficient (m-k), is aluminium Three to five times, the heat conductivility of the heat radiator 40 is considerably beyond aluminium profiles radiator.Meanwhile weight is also lighter than aluminium, subtracts The light dead weight of radiator.

Referring to Fig. 2, the both ends of the main part 41 of the heat radiator 40 respectively corresponding with the battery case 10 one A side wall 13 is fixedly connected.In the present embodiment, the both ends of the main part 41 respectively by a damping be flexible coupling 50 with A corresponding side wall 13 is fixed.The damping is flexible coupling 50 for elastomer connector.

When installation, the battery modules 20 are set in the battery case 10, at this point, the radiator 30 is set to It one end of the battery modules 20 and is spaced relatively with the installation gap 121.It is flexible coupling 50 by the stone by two dampings Black radiator 40 is fixedly connected with two side walls 13, at this point, multiple first be that radiating fin 42 is set in the battery case 10 And it is spaced relatively with the radiator 30.Multiple second radiating fins 43 are set to the electricity across the installation gap 121 Outside pond case 10.

When the battery modules 20 run work, the heat of the battery modules 20 electric discharge generation, which is dispersed into air, to be made Air themperature gets higher to form thermal current, and blows to the heat radiator 40, multiple first heat dissipations by the radiator 30 Temperature increases to make multiple first radiating fins 42 and multiple second on 41 both sides of the main part after fin 42 absorbs heat Radiating fin 43 forms temperature difference, on multiple second radiating fins 43 outside heat transfer to battery case 10, so that it is external Air is taken away, to realize the effect of rapid cooling.

Battery case radiator provided by the utility model combines heat dissipation with radiator fan using heat radiator, can have Effect provides radiating efficiency, meanwhile, heat radiator has the advantages that high-termal conductivity, light-weight, can promote the energy of battery case Density.
