Description
Technical field
The present invention relates to the technical field of battery tray, especially a kind of battery case of built-in liquid cooling system.
Background technique
Cooling device liquid cooling pipe in existing dynamic battery box is laid on tray substrate, and liquid cooling pipe can occupy inside pallet
Space.Liquid cooling pipe fitting is arranged inside pallet, and no heat preservation and fire prevention measure, coolant liquid have the risk revealed in pallet.
Liquid cooling system is larger by external environment influence, is easily reduced liquid cooling efficiency, and battery case is easy to cause in the case where thermal runaway
It is on fire.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of battery cases of built-in liquid cooling system.
The present invention is implemented as follows:
A kind of battery case of built-in liquid cooling system, including tray main body frame, frame-type protective plate, liquid cooling pipe, the support
Disc main body frame is spliced by front bezel, rear frame, left frame, left frame and bottom plate；The frame-type protective plate is set to
Below tray main body frame, frame-type protective plate surrounding is connected with bottom edge；The lower surface of base plate is arranged at intervals with multiple
Bottom plate boss, the bottom plate boss lower surface offer card slot compatible with liquid cooling pipe caliber, and the liquid cooling pipe is embedded in
The connection of itself and bottom plate is realized in card slot.
Optionally, the liquid cooling pipe is fixed in the card slot of bottom plate boss interior by soldering.
Optionally, the liquid cooling pipe is embedded in by way of interference fit in the card slot of bottom plate boss and is fixed.
Further, the liquid cooling pipe is in helicoid bending tube.
Further, the protective plate surrounding and bottom edge by welded seal in conjunction with.
In order to reduce influence of the external environment to liquid cooling system, guaranteeing liquid cooling efficiency and reduce caused by battery case thermal runaway
Risk on fire, the cavity formed between the bottom plate and frame-type protective plate is interior to be filled with flame-retardant foam material, constitutes flame-retardant expanded
Layer.
Further, the starting point of liquid cooling pipe and tail end are respectively inlet and liquid outlet, the inlet and liquid outlet
It is arranged on the same frame of tray main body frame.
Foaming layer can reduce influence of the external environment to liquid cooling system, guarantee liquid cooling efficiency, while using fire proofing material,
Risk on fire caused by battery case thermal runaway can be reduced.
The utility model has the advantages that
Liquid cooling pipe is embedded in realize its quick connection with bottom plate lower part in the card slot of bottom plate boss by the present invention, convenient
Fast, detachably；In addition, being caught in bottom plate lower part since liquid cooling pipe is equivalent to, avoid the leakage of liquid cooling liquid so as to cause battery pack quilt
The problem of corrosion and damage, greatly improves the security reliability of product.
Detailed description of the invention
Fig. 1 is pallet overall pattern of the invention；
Fig. 2 is bottom plate sectional view of the invention；
Drawing reference numeral explanation: 4. left frame of frame, 5. bottom plate, 51. bottom plate boss after 1. front bezel, 2. left frame 3.
6. 7. liquid cooling pipe of frame-type protective plate, 8. foaming layer
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, is not intended to limit the scope of the present invention..
A kind of battery case of built-in liquid cooling system, Fig. 2, the battery case of the built-in liquid cooling system include pallet master refering to fig. 1
Body frame, frame-type protective plate 6, liquid cooling pipe 7, the tray main body frame is by front bezel 1, rear frame 3, left frame 4, left frame
2 and bottom plate 5 be spliced；The frame-type protective plate 6 is set to below tray main body frame, 6 surrounding of frame-type protective plate and bottom
5 edge of plate is connected；5 lower surface of bottom plate is arranged at intervals with multiple bottom plate boss 51,51 lower surface of bottom plate boss
Card slot compatible with liquid cooling pipe caliber is offered, the liquid cooling pipe 7, which is embedded in the card slot of bottom plate boss 51, realizes itself and bottom
The connection of plate；Filling-foam material constitutes foaming layer 8 in the cavity formed between bottom plate 5 and frame-type protective plate 6.
Liquid cooling pipe 7 is coated on inside by bottom plate 5 and frame-type protective plate 6 in the present embodiment, can play object to liquid cooling pipe 7
Protective action is managed, after 6 solder bond of bottom plate 5 and frame-type protective plate, hair is injected in the cavity of bottom plate 5 and frame-type protective plate 6
Foam material.Foamed material fills up cavity, can reduce influence of the external environment to liquid cooling system, guarantees liquid cooling efficiency.It sends out simultaneously
Alveolar layer 8 uses fire proofing material, can reduce risk on fire caused by battery case thermal runaway.
