Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.
Fig. 1, Fig. 2 are please referred to, the embodiments of the present invention provide a kind of batteries management system of high current, including Radiator 10,20, two busbars 30 of Copper based electrical plate and multiple groups field-effect tube 40,20 one side of Copper based electrical plate attach In the radiator 10, field-effect tube 40 described in multiple groups is welded in 20 another side of Copper based electrical plate, and described in multiple groups Field-effect tube 40 is between two busbars 30 that 30 length direction of busbar is sequentially connected to parallel arrangement, due to practical application When, field-effect tube 40 can generate amount of heat, therefore multiple field-effect tube 40 are welded on Copper based electrical plate 20 by the present embodiment, The heat distributed can be transferred to Copper based electrical plate 20, and the radiator 10 by being close to Copper based electrical plate 20 scatters away.
As shown in Figure 1, Figure 3, two busbars 30 of the present embodiment are arranged in parallel, and multiple groups field-effect tube 40 is set to two remittances It flows between item 30, in order to improve the uniformity of 30 electric current of busbar distribution, each busbar 30 of the present embodiment includes converging An ontology 31 and connector 32 are flowed, offers at least one choked flow slot 311 on the busbar ontology 31, at least one described resistance The busbar ontology 31 is separated to form at least two diversion division 31a of both ends connection, and each diversion division by chute 311 It is connected with the connector 32 connection, its both ends with the field-effect tube 40 of identical quantity in the middle part of 31a, and each diversion division 31a Resistance setting all the same.The connector 32 of the present embodiment can be used for inputting or the connection of output conductor, in diversion division 31a Portion's connection may make that the electric current of input is conveyed from each middle part diversion division 31a to its both ends or portion is defeated thereto by its both ends It send, due to the identical setting of resistance of each diversion division 31a, therefore the electric current on each diversion division 31a is substantially the same, and is each led The quantity of the field-effect tube 40 of stream portion one end 31a connection is identical, therefore the electric current for flowing to every group of field-effect tube 40 is also roughly the same, The fluidisation for being conducive to improve electric current in field-effect tube 40 avoids current-unbalance in every group of field-effect tube 40 and leads to wherein one Electric current is excessive and damage in a or multiple field-effect tube 40.Wherein, the choked flow slot 311 of the present embodiment is set as two, then corresponds to Three diversion division 31a of formation, and field-effect tube 40 is 12 groups, and the one end each diversion division 31a is opposite with two groups of field-effect tube 40 It answers.It is understood that the choked flow slot 311 of other quantity can also be arranged, for example, when load current is wanted according to the size of water conservancy diversion It when asking bigger, then needs to be arranged more field-effect tube 40, then corresponding can open up more choked flow slots 311, such as 3,4 Or more, distribution electric current that can be more uniform.
Wherein, every group of field-effect tube 40 of the present embodiment is made of two field-effect tube 40 being arranged in series, can be certain The promotion operating voltage of degree, it is to be understood that every group of field-effect tube 40 can also be by 1,3 or more field-effect tube 40 It is in series.
When practical application, for the ease of the connection of multiple groups field-effect tube 40, described in the present embodiment, choked flow slot 311 is settable is in It is U-shaped comprising along the kerve 311a of 31 length direction of busbar ontology arrangement and from the both ends kerve 311a vertically to field-effect tube The separation trough 311b that 40 sides extend to form, and the length of multiple kerve 311a is by the opposite field-effect tube 40 1 of busbar ontology 31 It is free can be separated to form two generally U-shaped and adjacent diversion division 31a in being incremented by by side to its other side by diversion division 31a End is connected in opposite 40 side of field-effect tube, can set gradually convenient for multiple groups field-effect tube 40 along 30 length direction of busbar When, it can connection corresponding with multiple diversion division 31a.
Meanwhile an adjustment tank 312 is also provided on busbar ontology 31, it is parallel to kerve 311a setting, and close It is arranged in busbar ontology 31 with respect to 40 side of field-effect tube, advantageously ensures that each diversion division 31a is U-shaped, It is set as identical convenient for the subsequent resistance by multiple diversion division 31a.
As shown in Fig. 2, radiator 10 described in the present embodiment includes a heat sink 11, which can be used air-cooled dissipate Water cooled heat radiating can also be used in heat, and the present embodiment preferably uses water cooled heat radiating, and in order to improve water cooling efficiency, the present embodiment It is provided with the waterway 111 that multiple head and the tail are sequentially communicated in the heat sink 11, and water cooling pump 12 and a water cooling box 13 are set, The water inlet end of water cooling pump 12 is connect with water cooling box 13, and water outlet is connected to first waterway 111, and the last one waterway 111 are connected to water cooling box 13, and the cooling water circulation in water cooling box 13 is pumped into waterway 111 to take away field-effect tube 40 The heat distributed.It is understood that the radiator 10 of the present embodiment can also use any other existing radiating mode.
