Brief description of the drawings
Fig. 1 is the structural representation that the utility model battery bag liquid cooling system is installed in battery bag.
Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
The existing cold cooling system of battery bag liquid uses a feed tube, a drain pipe and multiple cooling fins.Cooling
Piece is parallel with one another, and feed tube and drain pipe are turned on by the capillary in it.The radiating although cooling medium circulates wherein,
It is consistent to cool down liquid stream but radiating effect is bad, in cooling fin inner capillary tube single first, from the direction of vertical cooling fin
See, coolant is to flow to opposite side from the side of battery bag；Secondly, capillary in cooling fin because mouth of pipe footpath it is thin, then go for a stroll
Its radius of turn is small during arrangement, along with sandwich wound postcapillary is arranged closely, not only increases channel interior cooling medium
The resistance of flowing, cooling medium consumption management is influenceed, while be unfavorable for cooling medium quick heat radiating.Due to said structure feature,
So that water inlet is larger with outlet temperature, and then cause whole battery bag radiating uneven.In addition, capillary in single cooling fin
Pipe is unfavorable for arranging because coolant is to flow to opposite side from the side of battery bag and coiling is complicated, also has to radiating one fixing
Ring.
Drawbacks described above, such as Fig. 1 are directed to for this, the utility model provides a kind of cold cooling system of battery bag liquid, including one
1, shunting drain pipe 2 of shunting feed tube and multiple convection type refrigerating modules.Point of the shunting feed tube 1
End and the shunting end of the shunting drain pipe 2 are flowed, both are arranged in parallel in battery modules front end.The shunting feed tube 1
Realize that one is split into two by three-way connection, the shunting drain pipe 2 realizes that one is split into also through three-way connection
Two.The shunting feed tube 1 extends from shunting to 4 outer both sides of battery modules, and the shunting drain pipe 2 is from shunting
Extend to 4 outer both sides of battery modules.The convection type refrigerating module includes the cooling capillary 31 of two rows parallel arrangement, described
Between convection type refrigerating module is connected in parallel on the feed tube 1 of the both sides of battery modules 4 by wherein one cooling capillary 31, and pass through
Another cooling capillary 31 is connected in parallel between the drain pipe 2 of the both sides of battery modules 4.Wherein, two rows cool down in capillary and housed
Flow to opposite cooling medium.
In terms of the vertical refrigerating module directions of Fig. 1, cooling capillary is respectively communicated with both sides in the convection type refrigerating module
Feed tube, drain pipe, existing cooling fin heat dissipation direction is changed, further shorten heat dissipation path, while in the vertical of battery bag
To provided with multistage convection type sinking path, make the radiating at each position of battery bag uniform.Meanwhile feed tube 1 is split into two, goes out
Liquid pipe 2 is split into two, and is distributed in battery modules both sides；Along with two in refrigerating module cool down capillaries, its
Interior setting flows to opposite cooling medium so that integral battery door bag chilling temperature is more balanced.
The convection type refrigerating module includes an at least cooling unit.It is each right when there is multiple convection type refrigerating modules
Include a cooling unit in streaming refrigerating module.The cooling capillary 31 of two parallel arrangements is provided with the cooling unit 3.It is cold
But the capillary 31 in unit 3 is connected in parallel between shunting feed tube 1 or shunting drain pipe 2 after turning to multistage.In order to carry
High heat loss through convection effect, and have a radiating effect of identical uniform segment in longitudinal direction side, in the cooling unit cooling capillary with
The port of feed tube or drain pipe connection has two, and both are arranged on the same side.It is preferred that cooling capillary in the cooling unit
From itself and turning coiling feed tube or drain pipe junction so that the capillary is parallel with feed tube or drain pipe, one section away from
Turned again from after coiling so that the cooling capillary tube parallels with coiling, until the cooling capillary pipe length one with coiling
One group of setting is completed after cause, multigroup continuous coiling structure is set by above-mentioned one group of set-up mode afterwards.
It is parallel provided with two in each 3 yuan of cooling list when including multiple cooling units in each convection type refrigerating module
The cooling capillary 31 of arrangement.Capillary 31 in cooling unit 3 is connected in parallel on shunting feed tube 1 or shunting after turning to multistage
Between formula drain pipe 2.Specifically, each cooling unit 3 is connected in series by cooling down capillary 31.For example, have two it is cold
But during unit, a cooling unit connects the shunting feed tube 1 of battery modules side by a cooling capillary one end, by another
The shunting feed tube 1 of a cooling capillary connection battery modules opposite side of the one end through another cooling unit；One cooling unit
The shunting drain pipe 2 of battery modules side is connected by another cooling capillary one end, it is single through another cooling by the other end
The shunting drain pipe 2 of another cooling capillary connection battery modules opposite side of member.In order to improve heat loss through convection effect, and
Have a radiating effect of identical uniform segment in longitudinal direction side, in the cooling unit cooling capillary be connected with feed tube or drain pipe or
The port of cooling capillary has two in another cooling unit, and both are arranged on the same side.It is preferred that cooled down in the cooling unit
Capillary is from itself and turning coiling cooling capillary junction in feed tube or drain pipe or another cooling unit so that the hair
Tubule coiling of being turned again after one segment distance, makes with cooling down capillary tube parallels in feed tube or drain pipe or another cooling unit
The cooling capillary tube parallels with coiling are obtained, one group of setting is completed after the cooling capillary pipe length with coiling is consistent, it
Multigroup continuous coiling structure is set by above-mentioned one group of set-up mode afterwards.
When a cooling unit is only set in each convection type refrigerating module, in order to preferably radiate, it is necessary to coiling compared with
Long cooling capillary.But once there is damaged, cooling medium outflow, damage battery performance, and not easy care.Therefore, every
Multiple cooling units are set to be considered as preferably in individual convection type refrigerating module.In addition, consider with reference to fluid resistance, convection type cooling mould
2-3 cooling unit of series connection, its radiating effect are optimal in block.
Cooling capillary arrangement in the utility model convection type refrigerating module is simple, the company between multiple cooling units
It is logical, directly it can be connected by the cooling capillary between cooling unit；Or be connected with each other by transfer tube, overcome conventional batteries
Wrap intricately winding mode.Simplification has been done from Structural assignments formula, and has accelerated heat and scatters and disappears.It is multiple described specifically from figure
Convection type refrigerating module is parallel with one another, and is uniformly arranged between the shunting feed tube 1 and shunting drain pipe 2.
Wherein, due to just there is two cooling capillaries in each cooling unit or convection type refrigerating module, in turning coiling
When, radius of turn is the radius of turn of two cooling capillaries, bigger than coiling radius in conventional batteries bag, and radius of turn ambassador
The internal drag suffered by cooling medium that must be circulated is smaller, and such cooling medium could quickly reduce battery bag when resistance is smaller
Temperature, have a significant impact to radiating efficiency.
