Wheel traveling, a kind of new-energy automobile having fewer environmental impacts.Vehicle power supply is battery, and the safety of battery is particularly important.
Existing electric automobile battery box generallys use the air-cooled type of cooling, causes battery specific heat load too low, is easy
Lead to hot-spot；Minority uses water-cooling pattern, but the design of cooling water channel structure owes rationally, to be also not enough to uniform and enough realities
The cooling of existing battery pack.
Utility model content
Technical problem to be solved in the utility model is that overcome the deficiencies of the prior art and provide a kind of structure simple, is dissipated
The electric automobile battery box body structure of good in thermal property.
The utility model solve its technical problem the technical solution adopted is that, electric automobile battery box body structure, including bottom
Plate, side plate and top plate, the bottom plate are put together by unit baseboard, and cooling water channel is equipped in each unit bottom plate, cooling water channel
The junction of water inlet flow channel and outlet passage is located at the end of unit baseboard, the upper table of the other end opposite with unit baseboard end
Face is equipped with water inlet pipe and outlet pipe, and wherein water inlet pipe connects water inlet flow channel, and outlet pipe connects the outlet passage, outlet pipe and into
Water pipe and water tank connection.
Further, the width of the water inlet flow channel of the cooling water channel is wider than the width of outlet passage, cooling water channel into
The ratio between water flow passage width and outlet passage width are 2:1.
Further, the cooling water channel is two-way, independent each other, the number of the unit baseboard between two-way water channel
>=2 are measured, passes through agitating friction between each bottom board unit and welds connection.
The utility model electric automobile battery box body structure has the positive effect that: cooling water is equipped in each unit bottom plate
Road, the water inlet flow channel of cooling water channel and the junction of outlet passage are located at the end of unit baseboard, opposite with unit baseboard end
The upper surface of the other end be equipped with water inlet pipe and outlet pipe, wherein water inlet pipe connects water inlet flow channel, and outlet pipe connects the water outlet
Runner, outlet pipe and water inlet pipe are connect with water tank, structurally reasonable, and cooling effect greatly improves, and heat dissipation performance is good.
Traditional water inlet flow channel width and outlet passage is of same size, and the width of the utility model water inlet flow channel is wider than water outlet
The width of runner, the ratio between water inlet flow channel width and outlet passage width of cooling water channel are 2:1, are compared with the traditional technology, can
To accelerate the flowing of cooling water, better cooling effect is played.
The utility model is two-way by setting cooling water channel, independent each other between two-way water channel, unit baseboard
Quantity is at least two pieces, is welded and is connected by agitating friction between each bottom board unit.Just in case when cooling water channel blocking occurs, also also
Other unit baseboards can cool down battery.

Spend the region of left and right two in direction.The structure of two-way cooling water channel is identical, now in conjunction with one of first unit bottom plate 11
Its structure is described in first via cooling water channel 4.
First via cooling water channel 4 is equipped with water inlet flow channel 41 and outlet passage 42, the company of water inlet flow channel 41 and outlet passage 42
The end that place is located at first unit bottom plate 11 is connect, the upper surface of the other end opposite with the end is equipped with water inlet pipe 44 and water outlet
Pipe 43, wherein water inlet pipe 44 connects water inlet flow channel 41, and outlet pipe 43 connects outlet passage 42, and outlet pipe 43 and water inlet pipe 44 are external
Water tank, water inlet pipe 44, water inlet flow channel 41, outlet passage 42, outlet pipe 43 form a complete water cooling circuit.The first via is cold
But 41 width of water inlet flow channel of water channel 4 is wider than outlet passage 42, and the ratio between the two width is 2:1；Water inlet flow channel 41 and outlet passage
42 junction is designed relatively narrow, can accelerate the flowing of cooling water, plays better cooling effect.
