Embodiment
The invention discloses a kind of temperature of powered cell adjusting device, realize adjustment,, prolonged its useful life to ensure the performance and the safety of electrokinetic cell to electrokinetic cell.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The temperature of powered cell adjusting device that the embodiment of the invention provides comprises the adjustment pipeline 2 that is used to be installed on the electrokinetic cell 1, and this adjustment pipeline 2 is used for supplying the adjustment media flow.Under condition of different; Different temperature is regulated medium and in adjustment pipeline 2, is flowed, and carries out heat exchange with electrokinetic cell 1, makes the temperature of electric power battery 1 obtain raising or reducing; To realize adjustment to electrokinetic cell 1; Guarantee that electrokinetic cell 1 works under optimal temperature conditions, ensure the performance and the safety of electrokinetic cell 1, prolong its useful life.
The temperature of powered cell adjusting device that the embodiment of the invention provides, its core inventive point are, regulate pipeline 2 through mounting temperature on electrokinetic cell 1; When condition of different temperatures is worked; In adjustment pipeline 2, inject and be used for the adjustment medium that heats up or lower the temperature, utilize adjustment medium flowing in adjustment pipeline 2, carry out heat exchange with electrokinetic cell 1; Make the temperature of electrokinetic cell 1 obtain raising or reducing; To realize adjustment to electrokinetic cell 1, the temperature gap when having reduced electrokinetic cell 1 work, control electrokinetic cell 1 is worked in optimum temperature range; Thereby ensured the performance and the safety of electrokinetic cell 1, prolonged the useful life of electrokinetic cell.
Please with reference to Fig. 2, electrokinetic cell 1 is combined by a plurality of battery cells, adjustment pipeline 2 can be installed in they around, top, following or middle.In the present embodiment; Adjustment pipeline 2 specifically is used to be installed between a plurality of compact arranged battery cell of electrokinetic cell 1; Can carry out heat exchange with a plurality of battery cells simultaneously, balanced each the battery cell temperature of ability, thus more effectively its temperature is regulated.
The kind of pipeline has many kinds, and adjustment pipeline 2 also can have various shapes, like linear, annular or the like.Here, please with reference to Fig. 1, adjustment pipeline 2 is specially coiled pipe.Such structure has bigger heat exchange area in narrow space between the battery cell, also just possessed better heat exchange effect, has adapted to the electrokinetic cell system compact structure, can control the temperature of electrokinetic cell module well.In addition, compare, install easier with adopting many pipelines side by side.
Temperature of powered cell adjusting device as shown in Figure 2, that the embodiment of the invention provides also comprises temperature adjusting plate 3, and it is to be used for vertically being arranged between a plurality of compact arranged battery cell of electrokinetic cell 1, and adjustment pipeline 2 is arranged on the temperature adjusting plate 3.Electrokinetic cell 1 is generally vertical setting, thereby temperature adjusting plate 3 vertically is provided with along the slit between its battery cell.3 pairs of adjustment pipelines 2 of temperature adjusting plate have played fixing effect; This mode is simple relatively; Simultaneously match in the slit that can put well between a plurality of compact arranged battery cell with electrokinetic cell 1 of its platy structure, also made things convenient for the installation and removal of adjustment pipeline 2.
The manufacturing materials of temperature adjusting plate 3 has a variety of, and wooden, ceramic perhaps metal or the like can.Concrete; Temperature adjusting plate 3 is formed by two aluminium alloy plate pressings, and low cost of manufacture is also very firm; The good thermal conduction characteristic of the material of its metal makes temperature adjusting plate 3 also can participate in heat transferred; Further enlarge the heat exchange area with electrokinetic cell 1, can help adjustment pipeline 2 and electrokinetic cell 1 to carry out heat transmission, and then promoted the performance of whole device.
As shown in Figure 1; Offer the snakelike mounting groove that cooperates with adjustment pipeline 2 on the temperature adjusting plate 3; Adjustment pipeline 2 just is installed in the snakelike mounting groove on the temperature adjusting plate 3, makes that its connection is more firm, and occupation space is littler; Adjustment pipeline 2 also contacts with temperature adjusting plate 3 better, has made full use of the auxiliary heat exchange of temperature adjusting plate 3.Certainly, adjustment pipeline 2 can also be arranged on the both sides of temperature adjusting plate 3, and principle is similar, repeats no more at this.
