The lost of life；And simple electric heating system only relies on conduction of heat, heating is less efficient.
The content of the invention
It is automobile-used to be used for homing guidance in ultra-low temperature surroundings (being less than -20 DEG C) the purpose of this utility model is to provide one kind
The heating unit of power lithium-ion battery system, cooperates with electrical heating to reach battery system fast in ultra-low temperature surroundings by fan
Fast uniformly heating.
The technical problem that the utility model is solved can be realized using following technical scheme：
A kind of fan cooperates with electrically heated Quick uniform heating battery heating system, it is characterised in that：Including being arranged on electricity
Electric heating system, conduction-convection problem and thermal diffusion system in the case of pond；The electric heating system mainly has more bulk resistors by inside
The electrically heated rod composition of silk, is arranged on bottom in battery case；The conduction-convection problem is mainly by being provided with different size venthole
Aluminium sheet forms, and is arranged on above electric heating system, electric heating system and battery core are separated；The thermal diffusion system is mainly by fan
And air-duct clapboard composition, the fan are arranged on the bottom of side in babinet, the air-duct clapboard is with box inside with wide, bottom
Conduction-convection problem is connected, passage is left in top, forms side and top air passage.
Preferably, heat-insulation system is further included, the heat-insulation system mainly sticks one layer of heat preservation cotton in box inside.
It make use of to Tthe utility model system the calorigenic action of electrically heated rod, the thermal diffusion facilitation of fan and aluminium sheet
Conduction of heat, the Quick uniform heating of battery system is realized, so as to ensure the normal of AGV battery systems under ultra-low temperature surroundings
Work.

Embodiment
The utility model is described in further detail with reference to embodiment, but the embodiment of the utility model is not
It is limited to this.
As Fig. 1,2 be the utility model preferred solution, including electric heating system, conduction-convection problem, thermal diffusion system and
Heat-insulation system.Arrow represents the flow direction of internal system gas in figure.
The electric heating system is mainly made of inside the electrically heated rod 2 of multiple resistance wire, is arranged in Battery case 5
In the middle part of the bottom in portion, 2 quantity of electrically heated rod is determined according to the group number and box width of battery core 1, and in the present embodiment, battery core 1, which is divided, is
Three groups, there is provided two electrically heated rods 2, are separately mounted to below the passage between three groups of battery cores 1.Electrically heated rod 2 is customizable not
Same heating power, main function is quick heat production.
The conduction-convection problem is mainly made of the aluminium sheet 3 for being provided with different size venthole 4, and aluminium sheet 3 is arranged on electrical heating
The top of rod 2, electrically heated rod 2 and battery core 1 are separated, and are provided with venthole 4 on the position of opposite battery core 1 on aluminium sheet 3, it is led
The heat for acting as producing electrically heated rod 2, which conducts rapidly, to be come, and is increased area of heat transfer, is improved heat transference efficiency.
The thermal diffusion system is mainly made of fan 9 and corresponding Duct design, its main function is by electrically heated rod
The heat of generation, which is spread apart rapidly, to be come, and ensures the uniformity in temperature field.In the present embodiment, thermal diffusion system is arranged on Battery case
Side inside 5, is made of fan 9 and air-duct clapboard 8, and air-duct clapboard 8 is vertically arranged, with the inside of Battery case 5 with width, by electricity
Pond management system 7 is separated with battery core 1, and top is left ventilating duct supply stream and passed through, and battery management system 7 is placed in air passage, fan 9
The side bottom in Battery case, the columns discharged according to battery core 1 set the quantity of fan 9, and main function is by electrically heated rod 2
The heat of generation is blown upwards, upward air-flow is formed in air passage, then flow to battery core 1 by the passage above air-duct clapboard.
The heat-insulation system mainly sticks one layer of heat preservation cotton 6 in the inner side of Battery case 5, for stopping inside battery system
Heat outwardly environment transmission.
The utility model determines the power of electrically heated rod 2 according to the specific heat capacity, quality and temperature rise of battery system internal material,
Smaller in view of AGV battery system sizes, transverse temperature difference is smaller than 3 DEG C, and the aperture by adjusting the venthole 4 on aluminium sheet is big
It is small, ensure that the air flow rate for flowing through each battery core 1 is consistent.Efficiency in view of thermal convection current is to increase from top to bottom, heat transfer
Efficiency is to increase from the bottom up.Heat conduction efficiency determines substantially, and thermal convective efficiency is adjusted by adjusting the flow of fan 9, from
And ensure that heat transference efficiency from top to bottom is basically identical, it is ensured that vertical temperature difference is again smaller than 3 DEG C.
