Description
Technical field
The utility model relates to a kind of hybrid vehicle batteries that has air-cooled forced heat radiation structure.
Background technology
Along with the development of hybrid vehicle technology, the progress of battery technology, battery power is increasing, and it is more and more littler to take volume, but corresponding caloric value also increases.And temperature has very big influence to the performance of battery, and therefore, high efficiency and heat radiation how makes battery operatedly in optimum working temperature, keeps the uniformity of battery pack temperature to become urgent day by day.The radiating condition of inside battery module is often abominable than external module in traditional design, therefore causes inside and outside battery performance to produce difference, reduces the overall performance of battery pack.
The battery pack of prior art is when ventilating, because pressure drop is bigger between battery pack air inlet and the air outlet, and battery module inside is bigger to the resistance of wind, the passage windage that forms between module outer rim and the casing is less, air-flow flows away from the module outer rim easily, this a part of air-flow only dispels the heat to the module at edge, and this causes the radiating condition reason more abominable than the edge of inside modules just.And the present invention can introduce more air-flow inside modules, strengthens the cooling of inner battery module, makes the integral heat sink condition more even.
Summary of the invention
The purpose of this utility model provides a kind of hybrid vehicle batteries of air-cooled forced heat radiation structure, and it is a kind of compact conformation, the batteries that radiating condition is good.
The utility model provides a kind of hybrid vehicle batteries that has the cooling channel heat abstractor, and it mainly comprises blower fan 1, casing 2, end plate 3, supporting and mounting bracket 4 and battery module 5.
Battery pack casing of the present utility model is square and the waveform combination.The first half is a square box, and the waveform casing is adopted in the bottom.Battery pack adopts air cooling way to carry out forced heat radiation.Air inlet is in a side of the Lower Half of casing.Air outlet at the top of casing away from a side of air inlet.
And the utility model adopts wavy shaped configuration in casing import department, and its smooth streamline can reduce flow resistance, just, strengthens the heat exchange of downstream battery.Corrugated structure has certain guide functions simultaneously, can guide more air-flow to enter the inside modules heat radiation.Traditional square box on the corner airflow direction sharply changes, easily cause backflow, draw and cause bigger energy loss, but when changing direction, part air-flow enters the module gap, participate in and strengthened the heat radiation cooling of internal module, therefore in structural design of the present utility model in the not good position of upper edge module heat dissipating, adopted squared design.
The import of casing is located at the below of cross section one side, and as the lower left corner, air-flow mainly is divided into two strands.The main air amount is less, and up the battery module to the upper left corner dispels the heat.The secondary air flow amount is bigger, the battery module that enters the right along following wedge shape intake channel successively dispels the heat, the aisle spare streamwise reduces gradually, the angle theta of casing and horizontal plane, also promptly and the θ angle of the angle of bottom half first row battery module between 0 °～30 °, optimized angle is between 0 °～10 °.
Present embodiment had both increased the blast in downstream, can guarantee the number of modules uniform distribution of air-flow again according to required cooling, the air-flow that just enters inside modules from the near place of import is many, according to the path of being passed by, the number of battery cells of the required cooling of this a part of air-flow is also many, from the import side of entering, ground inside modules far away, throughput is few, but the cell number of corresponding required cooling is also few.
In casing, battery module is fixed by a plurality of supporting and mounting bracket and left and right two end plates, and realizes electrical communication by the jockey that is placed in end plate inside.Open fixing hole and wind hole on supporting and mounting bracket, fixing hole is used for fixing the radial position of battery module, while and battery thermal contact conductance.End plate and supporting and mounting bracket can be that nonmetallic materials are made, and also can be made by lightweight metal material surface coated insulation material.
Battery module can in linely also can be staggered in casing, preferentially selects for use to be staggered.When being staggered, on the horizontal direction between two battery modules apart from S
1Should be between 1～20mm, the minimum spacing S of layer and the battery module of interlayer
2Should be between 1～20mm, the preferred 3～10mm of the utility model.
Battery module is arranged and is adopted staggered mode.When air-flow was plunderred the cylinder heat radiation outward, being staggered had better flow-disturbing effect than sequence arrangement, and increased the contact heat-exchanging area, and therefore staggered radiating effect is better, more even.
The advantage of the utility model battery pack box body structure is: adopt wavy shaped configuration at air inlet, reduce the energy consumption that flows, have drainage, make more air-flow participate in the heat radiation of internal module; Adopt square structure at upside, strengthened the heat exchange of edge battery.Inlet air flow is divided into two strands, is responsible for respectively the battery of angle on the air intake oral-lateral and air-out oral-lateral inferior horn is cooled off.The inducer flow area streamwise reduces gradually, has increased the blast in downstream, can guarantee the number of modules uniform distribution of air-flow according to required cooling again.
Blower fan can adopt centrifugal blower or cross flow fan in the utility model, preferentially adopts centrifugal blower.
The hybrid vehicle batteries that adopts present embodiment to make has good cooling results, internal temperature uniformity height, ventilation characteristic of low energy consumption, is applicable to the nickel-hydrogen accumulator group or the lithium-ions battery group that adopt cylindrical battery.
