Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Refer to Figures 1 to 5 , a battery box with an adaptive regulation function, including a box body 1, a battery 2, a phase change partition assembly 3 and a drainage assembly. A plurality of batteries 2 are assembled side by side in the box body 1, and a plurality of phase change partition assemblies 3 are respectively assembled between adjacent batteries 2. A fan assembly is fixedly installed on the rear wall of the front plate of the box body 1, and a plurality of drainage assemblies are fixedly installed on the inner side surface of the box body 1, and the drainage assemblies correspond to the phase change partition assemblies 3 one by one. The phase change partition assembly 3 is composed of phase change plates 31, and a plurality of phase change plates 31 are arranged in two columns in a staggered manner, and an air duct 32 is left between the phase change plates 31 in the same column.
[0022] The box body 1 is spliced by a bottom plate, a top plate, a front plate, a rear plate and two side plates, and a wire harness isolation plate and a copper row are arranged inside.
[0023] The phase change plate 31 is internally provided with a cavity for filling a phase change material. The phase change partition assembly 3 and the battery 2 are distributed in a staggered manner, and the principle of heat absorption and heat release during the phase change of the phase change material can be used for auxiliary temperature control, with good temperature control effect and energy saving.
[0024] As Figure 3 shown, the distribution of the phase change plates 31 and the position of the air duct 32 can be known. The drainage assembly is used to direct the air flow to the air duct 32, for exchanging the heat absorbed in the phase change plate 31 and dissipating it, and at the same time can perform auxiliary heat dissipation work on the battery 2 to improve the heat dissipation efficiency.
[0025] As Figure 2As shown, the drainage component includes a fixed cylinder 4 and a drainage mechanism 5. The fixed cylinder 4 is fixedly installed on the inner side surface of the box body 1.
[0026] As Figure 4 shown, the drainage mechanism 5 includes a rotating shaft 52 and a spiral bimetal sheet 53. A rotating block 51 is fixedly installed at the lower end of the rotating shaft 52. One end of the spiral bimetal sheet 53 is fixedly installed on the rotating block 51, and the other end of the spiral bimetal sheet 53 is fixedly installed on the inner wall of the fixed cylinder 4. The spiral bimetal sheet 53 is wound around the outside of the rotating shaft 52. A connecting block 54 is fixedly installed at the upper end of the rotating shaft 52. A fixing rod 55 is vertically fixedly installed at the outer end of the connecting block 54. A drainage plate 56 is integrally formed on the outer wall of the fixing rod 55.
[0027] The bimetal sheet is a composite structure composed of two metals with different coefficients of thermal expansion. When the temperature changes, the deformation of the active layer is greater than that of the passive layer, causing the bimetal sheet to bend towards the passive layer side. The spiral bimetal sheet 53 is composed of two metal sheets with different coefficients of thermal expansion and forms a spiral shape. The thermal expansion coefficient of the outer metal sheet is larger. When the temperature in the battery box rises, the deformation of the spiral bimetal sheet 53 will drive the drainage plate 56 to deflect and face the air duct 32. Being designed as a spiral shape can magnify the amount of deformation and improve its sensitivity to temperature.
[0028] The upper end of the spiral bimetal sheet 53 is fixed in the fixed cylinder 4, which is the fixed end, and the connection part between its lower end and the rotating block 51 is the movable end. When the temperature rises, the spiral bimetal sheet 53 deforms and twists, driving the rotating block 51 and the rotating shaft 52 to rotate. Through the transmission of the connecting block 54 and the fixing rod 55, the drainage plate 56 is driven to rotate. Therefore, the drainage mechanism 5 is a temperature control structure and can adjust the drainage plate 56 according to the temperature in the battery box by itself. When the drainage plate 56 deflects and faces the air duct 32, it can guide the airflow, enabling the airflow to smoothly enter the air duct 32 and directly act on the high-temperature part, improving the heat dissipation efficiency.
[0029] Figure 2 This is the battery box not in use. The drainage plate 56 is parallel to the side plate of the box body 1.
[0030] Specifically, as Figure 1 and Figure 2 shown, the fan assembly includes a support box body 11 and a fan. The support box body 11 is fixedly installed on the rear wall of the front plate of the box body 1, and a fan is arranged inside the support box body 11. A first filter screen 12 is assembled on the surface of the support box body 11 on the same side as the drainage component. An end cover 13 is fixedly installed on the front wall of the front plate of the box body 1, and filter holes are provided on the surface of the end cover 13. A rectangular hole is provided on the front wall of the front plate of the box body 1, and a second filter screen 14 is fixedly installed in the rectangular hole.
[0031] The design of the first filter screen 12 on the support box body 11 allows the air flow generated by the fan to flow out from the first filter screen 12. After flowing out, it first passes through the diversion mechanism 5, bypasses all the batteries, and then flows to the other side inside the battery box, and finally flows out from the second filter screen 14. When the diversion plate 56 deflects towards the air duct 32, part of the air flow will flow towards the air duct 32 under the guiding action of the diversion plate 56, and perform more effective heat dissipation work on the phase change plate 31 and the battery 2.
[0032] The settings of the first filter screen 12 and the second filter screen 14 can prevent dust in the outside air from falling into the battery box. The filter holes on the end cover 13 will not affect the inflow of air, and can block impurities in the air.
[0033] Specifically, as Figure 2 shown, limiting plates 15 are fixedly installed on the inner walls of the side plates and the rear plate of the box body 1.
[0034] The limiting plates 15 arranged inside the two side plates limit the position of the battery 2 from the left and right sides. The limiting plates 15 arranged inside the rear plate cooperate with the support box body 11 to limit the position of the battery 2 from the front and rear sides. Limiting plates 15 are arranged on the upper and lower sides inside the side plates and the rear plate of the box body 1, which will not affect the passage of air flow and ensure the stability of the installation of the battery 2.
[0035] The fixed cylinder 4 is installed on the limiting plate 15 below the inner wall of the side plate.
[0036] Specifically, as Figures 2 to 4 shown, the number of diversion plates 56 is the same as the number of air ducts 32, and the positions of the diversion plates 56 correspond to the positions of the air ducts 32.
[0037] The diversion plates 56 that perform diversion work after deflection will only guide part of the air flow and will not affect the passage of other air flows. Thus, all subsequent diversion plates 56 can guide part of the air flow into the corresponding air ducts 32.
[0038] Specifically, as Figure 2 and Figure 5 shown, a connector 61 is assembled on the front wall of the front plate of the box body 1, and a water inlet and a water outlet are respectively arranged on the connector 61. A cooling pipe 6 is arranged at the rear end of the connector 61, and the cooling pipe 6 winds around the outside of the battery 2 and the phase change partition assembly 3.
[0039] The water inlet and the water outlet are respectively connected to a water inlet pipe and a water outlet pipe. In the position where the cooling pipe 6 winds around the battery 2 for one week, the position on the side of the battery 2 is designed in a serpentine shape to assist in heat exchange and cooling of the battery 2.
[0040] Cooling water or low-temperature air can flow through the cooling pipe 6.
[0041] Specifically, a temperature sensor 7 and a processor are assembled inside the box body 1, and the processor is electrically connected to the fan assembly and the temperature sensor 7 respectively.
[0042] The temperature sensor 7 is used to measure the temperature inside the box body 1. After the temperature information is processed by the processor, it is used to control the operation of the fan.
[0043] During the normal operation of this battery box, mainly through the heat absorption characteristic of the phase change material in the phase change partition assembly 3, heat is absorbed and the temperature is maintained stable when the temperature rises. When the temperature continues to rise, the helical bimetallic strip 53 will be deformed by heat, driving the diversion plate 56 to deflect and gradually face the air duct 32. At the same time, when the temperature measured by the temperature sensor 7 exceeds the set threshold, the processor controls the operation of the fan to form a cooling air flow inside the battery box. Part of the air flow will flow through the air duct 32 under the action of the diversion plate 56, taking away the heat in the phase change plate 31 and dissipating heat from the battery 2, improving the cooling and heat dissipation effect of the internal space of the battery box and keeping the battery 2 within a suitable working temperature range;
[0044] In addition, cooling water or low-temperature air can be introduced into the cooling pipe 6 to further improve the efficiency of heat exchange and cooling.
[0045] When the temperature inside this battery box changes, the diversion mechanism 5 can adaptively adjust the angle of the diversion plate 56, and the processor can control the operation of the fan according to the temperature information. The cooperation of the two realizes the adaptive regulation of this battery box for cooling and heat dissipation, achieving a better heat dissipation effect while reducing energy consumption.
[0046] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, many changes can be made in the specific implementation manners and application scopes according to the idea of the present invention. As long as these changes do not depart from the concept of the present invention, they all belong to the protection scope of the present invention.
