Description
Technical field
It the utility model is related to batteries of electric automobile cooling field, and in particular to a kind of battery bag shunting cooling device.
Background technology
The energy storage component of electric automobile is generally lithium battery, and the main heating of lithium battery in the course of the work concentrates on lug
Part, traditional cooling device do not carry out temperature difference control to lug and other parts, and cooling effect is undesirable.
Utility model content
The utility model purpose is to provide for the battery bag shunting cooling device of a kind of point of gradient cooling, lug part
Coolant temperature it is minimum, and the coolant temperature at other positions of battery bag is slightly higher, and cooling gradient is reasonable, coolant cooling effectiveness
It is high.
To achieve these goals, the utility model uses following technical scheme：A kind of battery bag shunting cooling device,
Including upper coldplate and lower coldplate, upper coldplate and lower coldplate are internally provided with the runner for coolant flow, upper cooling
Plate is fixed on the upper end of lower coldplate, and the lower end of upper coldplate is laid with multiple delivery ports, and lower coldplate offers more side by side
Individual flow channel, the delivery port of the upper coldplate of upper end connection of flow channel, the lower end of multiple flow channels connects and led to cold
But export, upper coldplate connects cooling liquid inlet.
Further, in addition to import connecting plate and outlet connecting plate, import connecting plate and outlet connecting plate in open up
There is the runner for coolant flow, import connecting plate connects the upper coldplate of multiple arranged in parallel, and outlet connecting plate connection is multiple
The lower end of the lower coldplate of arranged in parallel.
Further, the solid slab of arc is connected between the two neighboring passage of lower coldplate.
Further, the lower surface of upper coldplate is provided with mounting groove, and the delivery port is uniformly laid in the groove of mounting groove
Bottom, lower coldplate insertion are fixed in mounting groove.
The utility model coolant is introduced into coldplate, and lower coldplate, upper cooling are flowed into after the shunting of upper coldplate
Plate is fixed on the lug position of battery, and lower coldplate is located at battery battery core position, and upper coldplate provides the chilling temperature to lug,
Lower coldplate provides the chilling temperature to battery core, and the coolant in upper coldplate flows into lower cool down after the heat exchange with lug
In plate, the coolant temperature in upper coldplate and lower coldplate changes in gradient, and it is cold to realize the big lug part of caloric value
But liquid temperature degree is low, and cooling capacity is strong, and the small battery core position coolant temperature of caloric value is slightly higher, and cooling effect is also good, even heat
Distribution, cools down, realizes efficient utilization of the coolant in cyclic process on demand.

The bottom land that delivery port is uniformly laid in mounting groove is stated, the lower insertion of coldplate 2 is fixed in mounting groove, and lower coldplate 2 opens up side by side
There are multiple flow channels, the solid slab 3 of arc, the side of solid slab 3 one are connected between the two neighboring flow channel of lower coldplate 2
Face increases heat exchange area, on the other hand, the battery core of lithium battery is set for card, plays fixation, the upper end of flow channel
The delivery port of coldplate 1 in connection, the lower end of multiple flow channels connect and lead to outlet connecting plate 5, upper coldplate connect into
The water channel for coolant flow is offered in mouth connecting plate 4, import connecting plate 4 and outlet connecting plate 5, import connecting plate 4 connects
Lead to the upper coldplate 1 of multiple arranged in parallel, outlet connecting plate 5 connects the lower end of the lower coldplate 2 of multiple arranged in parallel.
NM technology is prior art in the utility model.
The present embodiment is optimum embodiment, the foregoing is only the preferable specific implementation of technical solutions of the utility model
Example, rather than the restriction to technical solutions of the utility model, any those of ordinary skill in the art for being familiar with the technology are in this reality
With the variations and alternatives that in new suggested technical scope, can be made without creative thinking, should all cover at this
Within the protection domain of utility model right requirement.
