Abstract
The utility model provides a radiator for a battery pack, which can effectively improve the heat-radiating efficiency, is convenient to operate, reliable in performance and convenient to install and maintain. The radiator for the battery pack comprises a plurality of radiating fins and a temperature sensing system, wherein each radiating fin is L-shaped, and comprises an insert surface capable of being inserted between two battery cells of the battery pack, and a heat-radiating surface arranged at one side end of the insert surface and being perpendicular to the insert surface, and the width of the insert surface is smaller than that of the battery cell; and the temperature sensing system is installed on the insert surface of one radiating fin and electrically connected with a control system for a battery box.
Description
Technical field
The utility model relates to a kind of radiating device of battery pack for electric automobile battery box.
Background technology
Along with the aggravation of environmental pollution and the minimizing of petroleum resources, new-energy automobile more and more is subject to the favor of countries in the world, and the batteries of the new-energy automobile of China mainly adopts lithium battery.Batteries in use or when charging, each cell can the evolution of heat, if the heat radiation of battery pack shortcoming, the thermal accumlation of battery-heating bring impact can for the use of battery pack, might cause the unstable of battery pack, and shorten the life-span of battery pack.In order to improve heat radiation, generally can be provided with louvre on battery-pack exterior casing, circulate in battery pack by air and realize heat radiation.But such radiating mode, radiating rate is slow, and outside dust impurity can enter in battery case by louvre simultaneously, makes easily dirty even corrosion of battery pack, and impact is used.
Summary of the invention
In order to solve related defects and the weak point of above-mentioned existing batteries of electric automobile group heat radiation, the utility model provides a kind of can effectively improve radiating efficiency, and easy to operate, dependable performance, and be convenient to the radiating device of battery pack of installation and maintenance.
The utility model comprises several fin and temperature sense system; Described fin is the L-type plate, and it comprises the inserting surface that can insert between two battery cells of battery pack, and with one side end that is arranged at described inserting surface and the radiating surface vertical with described inserting surface, the width of described inserting surface is less than the width of battery cell; Described temperature sense system is arranged on the inserting surface of a fin, and is electrically connected to the control system of battery case.
In order to control more accurately and effectively battery pack temperature, described temperature sense system is arranged on the center of inserting surface of the fin that is positioned at the battery pack centre position.
Described temperature sense system comprises temperature sensor and holding wire, and temperature sensor is arranged on the inserting surface of the fin that is positioned at the battery pack centre position, and holding wire is electrically connected to the control system of temperature sensor and battery case respectively.
For strengthening radiating effect, the radiating surface of described fin arranges partition.
For preventing in the battery case use procedure, the battery cell heating is expanded and is formed extruding, and the cell expansion slotted eye is set on the inserting surface of the utility model fin, gives the cell expansion headspace.Described cell expansion slotted eye can be preferably the rectangular slotted eye of two Parallel Symmetrics.
The utility model is simple in structure, dependable performance, and is convenient to install, safeguard.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model practical application schematic diagram.
In figure: 1, fin, 2, the temperature sense system, 3, radiating surface, 4, the cell expansion groove, 5, fixing hole, 6, battery pack, 7, inserting surface, 8, cut off.
Embodiment
As shown in Figure 1, the utility model comprises fin 1, and fin 1 has an inserting surface 7 that can insert gap between each battery cell of battery pack, with vertical with inserting surface and be arranged at the radiating surface 3 of a limit end of inserting surface, radiating surface 3 is provided with and cuts off 8, to improve radiating effect; Two cell expansion grooves 4 and fixing hole 5 are set on inserting surface 7, and the width of inserting surface 7 is less than the width of battery cell simultaneously.
As shown in Figure 2, several fin 1 insert in battery pack 6, and are fixing by fixing hole 5.Insert the fin 1 in battery pack 6, the heat of battery pack 6 inside can be conducted to radiating surface 3 and dispel the heat.When each battery cell of battery pack 6 was stacked, the radiating surface that the radiating surface 3 of fin 1 forms a whole facilitated radiating treatment.
As shown in Figure 1, 2, temperature sense system 2 is installed in the center of the inserting surface 7 of the fin 1 in the centre position that is arranged at battery pack 6, because in whole battery pack 6, this position should be the highest position of temperature, temperature sense system 2 is arranged on this position, is convenient to the accurate control of battery pack temperature.When battery operated or charging, battery pack 6 heatings, the temperature in the centre of battery is the highest temperature at this moment, when this place's temperature surpasses the exothermic temperature requirement, temperature sense system 2 transmission of signals are to the battery pack control system, control system is sent signal to fan, and fan begins to radiating surface 3 heat radiations.
Fin 1 can select aluminium sheet or the good material of other heat-conductive characteristic to make.In addition, along with the frequent use of battery, battery can expand, and the part of expansion is offset by the cell expansion groove 4 of reserving, and has so just avoided the extruding between battery.
