[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0028] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] like Figures 3 to 7 As shown, the present invention provides a new energy vehicle circulation control device, a circulation pipeline is arranged on the top of the battery pack, and a cooling component and a heat storage component are connected to the circulation pipeline. When the battery pack needs to be cooled, the coolant in the cooling component is driven to circulate by a pump, and the coolant circulates through the circulation pipe, the internal flow pipe, the heat storage component connecting pipe, the energy exchange pipe, the cooling component, the cooling component outflow pipe, the return pipe and the circulation pipe in turn, taking away the heat from the battery pack, thereby realizing the cooling of the battery pack.

The internal liquid will store heat through the heat storage component. When the battery pack needs to be heated, the heat flow in the heat storage component will be directly extracted to supply heat to the battery pack, thereby realizing the recovery and utilization of waste heat. Please refer to Figure 1-Figure 3 , including: a battery pack 100, a circulation pipeline 200, a cooling component 300 and a heat storage component 400.

[0030] The battery pack 100 adopts a modular splicing power supply;

[0031] The circulation pipeline 200 is arranged at the top of the battery pack 100. The circulation pipeline 200 includes a circulation pipe 210, an internal flow pipeline 220, a pump 230, a heat storage assembly connecting pipeline 240, a heat storage assembly internal flow pipeline 250, a return pipe 260, a heat storage assembly outflow pipeline 270, and a cooling assembly outflow pipeline 280. The internal flow pipeline 220 is arranged at one end of the circulation pipe 210, and the pump 230 is arranged on the internal flow pipeline 220. The heat storage assembly connecting pipeline 240 and the heat storage assembly internal flow pipeline 250 are arranged at the tail end of the circulation pipe 210. The return pipe 260 is arranged at the other end of the circulation pipe 210, and the heat storage assembly outflow pipeline 270 and the cooling assembly outflow pipeline 280 are arranged on the return pipe 260.

[0032] A first set of valves 241 is provided on the heat storage component connecting pipeline 240, a second set of valves 251 is provided on the heat storage component inflow pipeline 250, a third set of valves 271 is provided on the heat storage component outflow pipeline 270, and a fourth set of valves 281 is provided on the cooling component outflow pipeline 280. The first set of valves 241, the second set of valves 251, the third set of valves 271 and the fourth set of valves 281 are all electrically controlled valves.

[0033] The pump 230 is a circulating pump, which is connected to the internal flow pipeline 220 through a flange. The pump 230 drives the liquid flow inside the pipeline and the box body to circulate, and the heat of the liquid flow is transferred through the pipeline to achieve heat exchange.

[0034] The cooling component 300 is connected to the cooling component outflow pipeline 280. A semiconductor refrigeration component is set inside the cooling component 300. When the temperature of the coolant inside the cooling component 300 rises, the coolant is cooled by the refrigeration component to ensure the cooling effect.

[0035] The heat storage component 400 is connected between the heat storage component internal flow pipeline 250 and the heat storage component external flow pipeline 270. The heat storage component 400 includes a heat resistance container 410 and an energy exchange pipeline 420. The two side walls of the heat resistance container 410 are respectively connected to the heat storage component internal flow pipeline 250 and the heat storage component external flow pipeline 270. The energy exchange pipeline 420 is set in the inner cavity of the heat resistance container 410, and the two ends of the energy exchange pipeline 420 are respectively connected to the heat storage component connecting pipeline 240 and the cooling component 300.

[0036] A heat insulation board is provided on the top of the circulation pipe 210, and the cooling component 300 and the heat storage component 400 are both provided on the top of the heat insulation board to prevent the heat on the circulation pipe 210 from being transferred to the cooling component 300 and the heat storage component 400.

[0037] The cooling assembly 300 and the inner wall of the heat-resisting container 410 are both provided with heat-insulating pads to improve the heat-insulating effect.

[0038] A pair of clamps 110 are attached to the battery pack 100, and both ends of the pair of clamps 110 are fixedly connected to the heat conducting plate 120. The heat conducting plate 120 is located at the top of the battery pack 100. A limiting groove 130 is provided in the heat conducting plate 120, and a circulation pipe 210 is provided inside the limiting groove 130.

[0039] The heat generated by the battery pack 100 during operation can be transferred to the circulation pipe 210 through the heat conducting plate 120 , and the coolant inside the circulation pipe 210 can quickly cool down the battery pack 100 , thereby increasing the cooling efficiency.

[0040] Slide grooves 140 are provided on both sides of the heat conducting plate 120 , and a guide rail 150 is slidably connected inside the slide groove 140 . A clamping plate 160 is fixedly connected to the guide rail 150 . A clamping block 170 is fixedly connected to the bottom end of the clamping plate 160 , and the clamping block 170 is clamped inside the limiting groove 130 .

[0041] By using the limiting groove 130 in conjunction with the clamping block 170 , the circulation pipe 210 can be tightly attached to the heat conducting plate 120 , thereby avoiding the phenomenon of a gap between the circulation pipe 210 and the heat conducting plate 120 .

[0042] The two sides of the clamping plate 160 are fixedly connected with a rotating shaft 171, and the rotating shaft 171 is rotatably connected to a limiting plate 172, and the limiting plate 172 is fixedly connected to a fixing column 173. The limiting plate 172 is provided with a card slot 174, and the card slot 174 is clamped on the shaft pin 175, and the shaft pin 175 is fixedly connected to both sides of the heat conducting plate 120.

[0043] When it is necessary to remove the clamping plate 160 to disassemble the circulation pipe 210, pull the fixing column 173 upward to disengage the axle pin 175 from the slot 174, and then push the clamping plate 160 to disengage the guide rail 150 from the slide groove 140, thereby facilitating the disassembly of the circulation pipe 210.

[0044] During specific use, when cooling is required, the second valve group 251 and the third valve group 271 are closed, and the first valve group 241 and the fourth valve group 281 are opened. The pump 230 drives the liquid flow in the cooling component 300 to circulate. The liquid flows through the circulation pipe 210, the internal flow pipe 220, the heat storage component connecting pipe 240, the energy exchange pipe 420, the cooling component 300, the cooling component external flow pipe 280, the return pipe 260 and the circulation pipe 210 in sequence to achieve circulation. The circulating coolant takes away the heat generated by the battery pack 100 at work to achieve cooling. During the process, the energy exchange pipe 420 transfers the heat of the internally circulating coolant to the coolant inside the heat storage component 400, heats the coolant stored in the heat storage component 400, and realizes the recovery and utilization of waste heat.

[0045] When heating is required, the second valve group 251 and the third valve group 271 are opened, and the first valve group 241 and the fourth valve group 281 are closed, so that the pump 230 drives the liquid flow in the heat storage assembly 400 to circulate, so that the liquid flow passes through the heat storage assembly 400, the heat storage assembly outflow pipeline 270, the return liquid pipe 260, the circulation pipe 210, the internal flow pipeline 220, the heat storage assembly internal flow pipeline 250 and the heat storage assembly 400 to circulate, thereby heating the battery pack 100 and preventing the battery activity from being affected by the low temperature in winter.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
